However, in the case of a hanging structure in which the ceiling frame is hung on a horizontal member by using the hanging bolt of the rod shaft structure and the mounting bracket of the hook structure and the hanger structure as described above, first, the strength of the hanging bolt itself, the horizontal member and the hanging bolt There is a drawback that the connection strength with and the connection strength between the hanging bolt and the field edge holder is low, and the earthquake resistance when the ceiling frame is suspended is lacking.

For example, the exciting force at the time of an earthquake includes vertical vibration due to pitching and horizontal vibration due to rolling, and in reality, these vibrations are combined in a more complicated manner. Therefore, in addition to the vertical load, the horizontal load is also applied to the hanging bolt and the upper and lower mounting brackets, and it is required that the suspension bolt and the upper and lower mounting brackets have sufficient seismic resistance against the load in both directions.

However, the hanging bolts of the rod shaft structure alone and the mounting brackets of the hook structure and hanger structure cannot meet such demands, the hanging bolts are bent, and the hooks and hangers are disengaged. There is a risk of.

Therefore, in the conventional configuration, it is necessary to install a brace material to cope with the above-mentioned rolling, and to take measures for fixing the hook portion and the hanger portion.

The present invention has been made to solve such a problem, and the cross-sectional area is effectively expanded by forming the ceiling frame suspension material with a predetermined cross-sectional shape and a predetermined outer diameter dimension of shaped steel or steel pipe. However, the strength against compression / tensile load in the vertical direction, the strength in the direction perpendicular to the axis, and the strength in the horizontal direction are improved, and the ceiling frame is suspended from shaped steel or steel pipe having the predetermined cross-sectional shape and predetermined outer diameter. Strength of the ceiling frame suspension part by connecting the upper end side of the material to the horizontal material for mounting the ceiling frame on the building side via a predetermined mounting bracket and the lower end side to the ceiling frame via a predetermined connecting bracket. It is an object of the present invention to provide a ceiling frame suspension structure with greatly improved earthquake resistance.

The ceiling frame suspension structure of the present invention is configured to provide the following problem-solving means in order to solve the above-mentioned problems.

(1) First Problem Solving Means First, in the ceiling frame hanging structure in the first problem solving means of the present invention, for hanging the ceiling frame corresponding to the ceiling structure of the building on the ceiling base side to which the ceiling frame is attached. This is a ceiling frame hanging structure in which a horizontal member is provided, and a grid-like ceiling frame consisting of a field edge and a field edge receiver is hung from the horizontal member via the ceiling frame hanging material. The side horizontal member and the ceiling frame hanging member are each composed of a shaped steel or steel pipe having a predetermined cross-sectional shape and a predetermined outer diameter dimension, and the upper end of the ceiling frame hanging member is placed horizontally on the ceiling base side via a predetermined mounting bracket. It is characterized in that the ceiling frame is connected in a vertical state intersecting the materials, and the ceiling frame is connected and supported at the lower end of the ceiling frame hanging material in a crossed state via a predetermined connecting metal fitting.

In the configuration of the problem-solving means of the present invention, the ceiling base side horizontal member of the building and the ceiling frame hanging member that suspends the ceiling frame with respect to the ceiling base side horizontal member have a predetermined cross-sectional shape and a predetermined outer diameter, respectively. It is composed of shaped steel or steel pipe.

Therefore, not only the rigidity and strength of the horizontal material on the base side of the ceiling to which the ceiling frame suspension material is attached increases, but also the strength of the ceiling frame suspension material itself with respect to the vertical compression / tensile load and the rigidity in the direction perpendicular to the axis, horizontal The strength in the direction is greatly improved as compared with the case of the conventional bolt shaft.

Therefore, it is possible to configure the ceiling as a wind-resistant ceiling corresponding to a case where an upward wind pressure acts on the ceiling frame suspension portion and a compressive load is applied to the ceiling frame suspension material.

In this case, for example, a C-shaped steel is used as the shaped steel and a square steel pipe is used as the steel pipe for the horizontal member on the ceiling base side. Further, as the ceiling frame suspension material, for example, lip channel steel and channel steel as shaped steel, square steel pipe as steel pipe, and circular steel pipe as needed are adopted.

Moreover, in the same configuration, the ceiling base side horizontal member is connected to the ceiling base side horizontal member via a single mounting bracket integrally provided with a mounting portion to be attached to the ceiling base side horizontal member and a mounting portion for attaching the ceiling frame hanging material. On the other hand, the ceiling frame hanging members are attached so as to intersect in the vertical direction.

As a result, the single mounting bracket ensures that the high-strength horizontal lumber on the ceiling base side and the ceiling frame suspension member are positioned in the axial direction at which they intersect each other, and are firmly connected.

Therefore, by using the same mounting bracket, it is not necessary to adjust the axial position of the ceiling frame hanging member with respect to the horizontal member on the ceiling base side during the connecting operation, and the connecting strength of the connecting portion is also increased.

As a result, the seismic resistance against pitching and rolling of the ceiling frame hanging portion with respect to the horizontal lumber on the ceiling base side at the time of an earthquake is effectively improved. As a result, it is not necessary to install a brace material and take measures to fix the engaging portion as in the case of the conventional hanging bolt structure.

Further, the ceiling frame is connected to the lower end of the ceiling frame hanging member in a crossed state via a predetermined connecting metal fitting, and is reliably supported.

(2) Second Problem Solving Means Next, in the configuration of the first problem solving means of the present invention, the ceiling frame hanging structure in the second problem solving means of the present invention has the upper end of the ceiling frame hanging material. The predetermined mounting bracket to be mounted so as to intersect the ceiling base side horizontal member is a U-shaped cross section in which the mounting portion to be mounted on the ceiling base side horizontal member is slidably fitted to the outer periphery of the ceiling base side horizontal member. The mounting part formed at the joint and to which the ceiling frame hanging material is attached is located on both the upper and lower ends of the U-shaped fitting part that is slidably fitted to the outer circumference of the horizontal material on the ceiling base side. It is characterized in that it is formed in a pair of upper and lower fitting portions that slidably fit the hanging material.

In this way, the upper end of the ceiling frame suspension material made of shaped steel or steel pipe is attached to the horizontal material on the ceiling base side of the mounting bracket that is connected in a state of intersecting with the horizontal material on the ceiling base side also made of shaped steel or steel pipe. The mounting portion is formed in a fitting portion having a U-shaped cross section that is slidably fitted to the outer periphery of the horizontal member on the ceiling base side, and the mounting portion for mounting the ceiling frame hanging member is the horizontal member on the ceiling base side. It is said that it is formed in a pair of upper and lower fitting portions that are slidably fitted to the outer periphery of the above-mentioned ceiling frame on both upper and lower ends of a U-shaped fitting portion that is slidably fitted. , The following effects can be obtained.

That is, first, the fitting portion having a U-shaped cross section with respect to the horizontal member on the ceiling base side is slidably fitted to the outer circumference of the horizontal member on the ceiling base side, and is held after being positioned in the horizontal direction.

Next, in the same state, a pair of upper and lower surfaces for slidably fitting the ceiling frame suspending material on both upper and lower ends of the U-shaped fitting portion fitted to the outer circumference of the horizontal member on the ceiling base side. The ceiling frame hanging material is slidably fitted to the fitting portion of the above, and the height position in the vertical direction is adjusted.

Finally, each of these parts is fastened and fixed to the corresponding horizontal lumber and ceiling frame hanging lumber using screw members and the like.

As a result, the ceiling frame hanging member is firmly connected and integrated with the ceiling base side horizontal member via one high-strength mounting bracket.

As described above, in the same configuration, the mounting bracket is made of one metal member, and has a function of mounting and integrating the two members, the horizontal member and the ceiling frame hanging member, and positioning.

Therefore, as compared with the case of the hanging bolt structure described above, not only the hanging strength and the seismic strength are high, but also the mounting work thereof becomes remarkably easy.

Moreover, in the case of the same configuration, the mounting portion for the ceiling frame hanging material, and the fitting portion for slidably fitting and inserting the ceiling frame hanging material is the ceiling base side mounting portion, and the ceiling base side horizontal member. It is located on the upper and lower ends of the U-shaped fitting portion that is slidably fitted to the ceiling, and two sets are provided at a predetermined distance.

Therefore, the vertical positioning and position fixing are ensured, and the mounting can be more firmly fixed at two places.

(3) Third Problem Solving Means Next, in the ceiling frame hanging structure in the third problem solving means of the present invention, the ceiling frame hanging material can be slid in the configuration of the second problem solving means of the present invention. The pair of upper and lower fitting portions to be fitted to the ceiling base side are characterized in that they are integrally formed with a fitting portion having a U-shaped cross section that is slidably fitted to the outer periphery of the horizontal member on the ceiling base side.

In the case of such a configuration, by cutting the metal plate into a predetermined shape and bending it into a predetermined shape, three sets of fitting portions can be formed relatively easily.

(4) Fourth Problem Solving Means Next, the ceiling frame suspending structure in the fourth problem solving means of the present invention is slidable in the configuration of the second problem solving means of the present invention. The pair of upper and lower fitting portions to be fitted to the ceiling base side horizontal member are configured separately from the fitting portion having a U-shaped cross section that is slidably fitted to the outer circumference of the ceiling base side horizontal member. It is characterized in that it is integrated by being welded to the mounting edges provided on the upper and lower end sides of the fitting portion having a U-shaped cross section that is slidably fitted to the.

Like the ceiling frame hanging structure in the third problem-solving means, a pair of upper and lower fitting portions for slidably fitting the ceiling frame hanging material are slidably fitted to the outer periphery of the ceiling base side horizontal material. When it is integrally formed with the fitting portion having a U-shaped cross section, it can be formed by cutting and bending one metal plate, but the metal material is wasted due to the cutting, and the metal plate is bent. Processing is complicated, manufacturing efficiency is poor, and cost increases.

Therefore, a pair of upper and lower fitting portions for slidably fitting the ceiling frame hanging material is configured separately from the fitting portion having a U-shaped cross section that is slidably fitted to the outer periphery of the horizontal member on the ceiling base side. On the other hand, mounting edges are provided on the upper and lower ends of the U-shaped fitting portion that is slidably fitted to the outer circumference of the horizontal member on the ceiling base side, and welded to and integrated with the mounting edge. To do.

With such a configuration, a fitting portion having a U-shaped cross section that is slidably fitted to the outer periphery of the horizontal member on the ceiling base side is formed, for example, in a hat shape in cross section, and the edges on both ends thereof are suspended from the ceiling frame. It can be a mounting edge of a pair of upper and lower fitting portions for slidably fitting the materials.

Then, if a pair of upper and lower fitting portions for slidably fitting the ceiling frame hanging material to the mounting edges are joined by welding to be integrated, the same configuration as the one is easier. Can be configured in.

( 5 ) Fifth Problem Solving Means Next, the ceiling frame suspension structure in the fifth problem solving means of the present invention is a mounting bracket in the configuration of the second, third or fourth problem solving means of the present invention. The pair of upper and lower fitting portions for slidably fitting the ceiling frame hanging member of the above are characterized in that they are formed in a tubular body having a square cross section.

In the case of the problem-solving means of the present invention, the pair of upper and lower fitting portions for slidably fitting the ceiling frame suspending member of the mounting bracket are formed as a tubular body having a closed cross-section structure as a whole.

In the case of such a configuration, the ceiling frame suspending material is fitted and inserted into the tubular body having a square cross section in a slidable state, and is reliably held in the same state. Therefore, the sliding operation of the ceiling frame hanging material and the adjustment of the height position in the vertical direction become remarkably easy. In addition, the holding power after mounting is also increased.

Then, thus the case, a square cross section of the cylindrical body of the ceiling frame hanging member fit interpolating, if the integral structure as the third problem solving means, of course, the closed cross section The back wall portion is integrally continuous with the U-shaped cross-section fitting portion that is slidably fitted to the outer circumference of the horizontal member on the ceiling base side.

On the other hand, in the case of a separate structure such as the fourth problem-solving means, the U-shaped cross-section fitting portion in which the closed cross-section back wall portion is slidably fitted to the outer circumference of the horizontal member on the ceiling base side. configuration is employed to integrate with welded to the mounting edge.

As in the configuration of the first, second, third, fourth or fifth problem-solving means of the present invention, the upper end side is attached to the lower end of the ceiling frame hanging material attached to the ceiling base side horizontal member. When installing a ceiling frame, conventionally, the field edge receiving portion that supports the field edge of the ceiling frame consisting of the field edge and the field edge receiver is aligned with the lower end portion to which the ceiling frame hanging material should be attached in a crossed state and drilled. A direct connection method was adopted in which screws were screwed together.

However, the field edge receiving portion that supports the field edge of the ceiling frame composed of the field edge and the field edge receiving is easily bent by the load and is not always maintained in a horizontal state. Therefore, the alignment itself is not always easy. In addition, the drill screw must be screwed after the operator maintains the crossed state (overlapping state) in which the drill screw is screwed, and the position shift occurs due to the rotational force and vibration during the screwing of the drill screw. There are problems that are likely to occur. Further, it cannot be said that the load supporting strength at the connecting portion is sufficient only by directly connecting the field edge holder to the lower end portion of the ceiling frame hanging material with a drill screw.

Therefore, in the problem-solving means of the present invention, the ceiling frame (field edge receiver) is connected to the lower end of the ceiling frame hanging member via a high-strength connecting metal fitting, and the connecting metal fitting is connected to the ceiling frame. It is configured to have a position adjusting function so that the ceiling frame can be connected and supported after adjusting the height position in the vertical direction to be attached.

A second metal fitting is provided, and the second metal fitting is provided via a connecting bolt that is slidably held in the vertical direction through a slot for adjusting the height position provided in the first metal fitting. It is connected to an arbitrary height position of the first bracket, and characterized in that it is adapted to couple support ceiling frame at any height position of the first fitting.

In the configuration of the problem-solving means of the present invention, the connection position for connecting and supporting the ceiling frame according to claim 6 is provided, and the height position of the ceiling frame in the vertical direction is adjusted and then the ceiling frame is connected and supported. The first metal fitting is positioned and fixed to the lower end of the ceiling frame hanging material, and the second metal fitting is slidably fitted to the lower end of the ceiling frame hanging material via the first metal fitting. The second metal fitting can be any of the first metal fittings via a connecting bolt that is held so as to be slidable in the vertical direction through a slot for height position adjustment provided in the first metal fitting. It is connected to the height position, and at any height position of the first metal fitting that is connected, it is finally fixed to the lower end of the ceiling frame hanging material with a drill screw or the like to connect the top frame. It has come to support.

Therefore, according to such a configuration, first, the first bracket fixed on which is positioned at the lower end portion of the roof frame hanging member, ceiling against the ceiling frame hanging member through a fitting of the first When the second metal fitting for mounting the well frame is fitted, the second metal fitting for mounting the ceiling frame is mounted via a connecting bolt that is slidably supported in the vertical direction through an elongated hole having a predetermined length in the vertical direction. The metal fitting can be connected to the first metal fitting in a vertically slidable state. Therefore, in the same state, the height of the second metal fitting for mounting the top frame is adjusted to set an accurate mounting position.

Then, if the ceiling frame (the field edge receiving portion) is fitted to the ceiling frame fitting portion of the second metal fitting for attaching the ceiling frame, the ceiling frame can be finally attached at an appropriate position. can.

The height adjustment span of the ceiling frame mounting position relative to the ceiling frame hanging member in this case, determined by the vertical length of the elongated hole of the first bracket supporting the connecting bolts. Connecting bolts, at the time of height adjustment serves the temporary fixing function for the first fitting of a second bracket for ceiling frame mounting, but a second bracket for ceiling frame mounting during height adjustment completion the via first metal member functions to fix the lower material suspended ceiling frame.

( 8 ) Eighth Problem Solving Means Next , in the configuration of the seventh problem solving means of the present invention, the ceiling frame suspension structure in the eighth problem solving means of the present invention is provided on the ceiling in the first metal fitting. It is characterized in that a fitting claw that is fitted to the frame suspension material is provided.

According to this construction, when fixing the first bracket to the ceiling frame hanging member may be temporarily fixed in a state of being reliably positioned the first bracket to the ceiling frame hanging material, also work Even if the person does not support it by hand, it is securely held in the positioned state, and even if the drill screw is screwed, it can be fixed accurately without misalignment.

Therefore, the operability for fixing the first bracket to the ceiling frame hanging member is improved as well, ceiling frame via a first fitting of a second bracket for fitting and fixing the ceiling frame It facilitates the adjustment of the mounting position relative to hanging member is also improved mounting accuracy of the ceiling frame for ceiling frame suspended material.

( 9 ) Ninth Problem Solving Means Next, the ceiling frame suspension structure in the ninth problem solving means of the present invention is the ceiling frame suspension of the first metal fitting in the configuration of the eighth problem solving means of the present invention. The fitting claws fitted to the lowering material are the first fitting claws on both sides of the upper end of the first metal fitting and fitted to the left and right sides of the ceiling frame hanging material, and the first metal fitting. It is characterized by consisting of second fitting claws on the left and right sides of the end surface of the lower end portion of the ceiling frame, which are abutted and engaged with the left and right sides of the end surface of the lower end portion of the first metal fitting mounting surface of the ceiling frame hanging member.

According to this construction, when fixing the first bracket to the lower end portion of the ceiling frame hanging member, a second fitting claws of the lower end surface of the first metal fitting heavenly frame hanging member first of the lower end face of the fitting attachment surface by abutting engagement, with determining the mounting position in the vertical direction, the first fitting pawl of the upper end sides of the first metal fitting ceiling frame hanging member By fitting on both sides, the mounting position in the left-right direction can be determined, and the entire body can be securely temporarily fixed. That is, according to the same configuration, it is possible to accurately position each of the upper, lower, left, and right mounting positions, securely temporarily fix the mounting position, and then fix the mounting position with a drill screw.

As a result, even if the operator does not support it by hand, it is surely held in the positioned state, and even if the drill screw is screwed, it can be accurately fixed without any misalignment.

Therefore, the operability for fixing the first bracket to lowering material hanging heavenly frame is improved as well, hanging ceiling frame via a first fitting of a second bracket for fitting and fixing the ceiling frame It facilitates the adjustment of the mounting position relative to lower member is also improved mounting accuracy of the ceiling frame for ceiling frame suspended material.

In this case, the second fitting claws on the left and right sides of the lower end surface of the first metal fitting and which are abutted and engaged with the left and right sides of the lower end surface of the first metal fitting mounting surface of the ceiling frame hanging member are simply claws. A part of the lower end of the main body may be bent 90 degrees, or the tip of the bent piece of the same 90 degrees may be further bent 90 degrees to form a cono shape, leaving a predetermined gap, and the lower end of the ceiling frame hanging material.

In the XY directions of the ceiling base, for example, as shown in FIG. 13, a plurality of horizontal steel pipes having a predetermined outer diameter are formed. The grid-like ceiling frame composed of the field edge 7 and the field edge receiver 6 is suspended in a stable state with good earthquake resistance via the ceiling frame hanging members 10, 10, ... (This horizontal reinforcing material). Details of the ceiling frame suspension structure for 3,3 ..., 3,3 ... will be described later).

In the configuration of FIG. 13, the ceiling base portion above the vertical material (reinforcing material suspending material) 70, 70 ... Of the ceiling base of FIG. 1 is omitted, and the horizontal reinforcing material in the XY direction is shown. 3,3 ..., 3,3 ... Also omits the horizontal reinforcing material 3,3 ... in the X direction, and shows only the horizontal reinforcing material 3,3 ... in the Y direction.

Length of the vertical material (reinforcing material hanging material) 70, 70 ... of the basic ceiling base part that suspends and supports the horizontal reinforcing materials 3, 3 ..., 3, 3 ... for mounting the ceiling frame. For example, the sword is formed to have dimensions according to the depth of the ceiling of the building, and brace materials 80, 80 ... Consisting of square steel pipes having predetermined external dimensions are inserted and connected diagonally from both the left and right sides between them. , The horizontal reinforcing members 3, 3 ..., 3, 3 ... in the XY directions are configured to have sufficiently high seismic strength against rolling.

For the purpose of improving the seismic strength, various structures can be considered as the rectangular steel pipe for the vertical material 70, but in the case of this embodiment, for example, as shown in FIG. 2, a predetermined plate A thick metal plate is bent into a square or rectangular cross section, and both side edges 70a and 70b are connected by tying each other in an S shape at one side A part of the corner, and adjacent to one side edge. By providing a bent rib 70c on the inside of the portion, the tying portion is fixed and integrated into a square cylinder. The same applies to the square steel pipe for the horizontal reinforcing member 3 and the square steel pipe for the brace material 80.

Further, a square cup-shaped reinforcing metal fitting 90A is provided at either the upper or lower end (or both ends) of the vertical members 70, 70 ... If necessary (see FIGS. 9 to 10).

(About the mounting structure for the mounting edges 60a, 60a ... of the vertical members 70, 70 ... H-shaped steel 60, 60 ... at the upper end)
The vertical members 70, 70 ... Have their upper ends with respect to the mounting edges 60a, 60a ... Of the H-shaped steels 60, 60 ..., as shown in FIGS. 3 and 12, for example, the vertical member mounting brackets. It is firmly attached using 61 and the auxiliary metal fitting 64.

The vertical member mounting bracket 61 has a bottom wall surface (abutment seat surface) 610 that is abutted in a stable seating state corresponding to the cross-sectional area and cross-sectional shape of the upper end portion of the vertical member 70 made of the square steel pipe having a square cross section. A rectangular box-shaped mounting bracket main body 61a (a rectangular parallelepiped shape in which the entire front side is opened in a U shape in the horizontal direction) and a front side of the mounting bracket main body 61a (the mounting edge portion 60a side of the H-shaped steel 60). ), And the fitting ports 61b, 61b having a U-shaped cross section with a predetermined depth in the front-rear direction, and the fitting ports 61b, 61b located on the upper wall surface 611 side of the central portion in the front-rear direction, are provided from the upper side to the lower side. It is composed of a fastening bolt 61c that is inserted and screwed from the upper side to the lower side at the time of mounting and fixes the mounting bracket main body 61a to the mounting edge portion 60a of the H-shaped steel 60 from above. ..

The fastening bolt 61c is screwed into the fastening bolt screw hole via, for example, a spring washer 61j and a locking nut 61h.

The fitting ports 61b and 61b are formed by notching the left and right side walls 612 and 612 of the front side opening of the mounting bracket main body 61a to a predetermined depth on the rear side. In the case of this embodiment, the fitting ports 61b and 61b are provided in the front half portion in the substantially front-rear direction when viewed from the side surface of the mounting bracket main body 61a.

On the other hand, substantially the entire bottom wall 610 is in contact with the upper end of the vertical material 70, and in the same contact state, the vertical material is provided by bolts 63a via a pair of connecting brackets 62a and 62a provided on both the left and right sides of the bottom. The upper ends of 70, 70 ... are firmly connected and integrated.

In the case of such a configuration, the vertical members 70, 70 ... Are made of square steel pipes having a square cross section, and the vertical member mounting brackets 61 are also formed in a square box shape, and one of them is vertically provided. It is integrally connected to the square material structure of. Then, it is firmly attached to the attachment edge portion 10a of the H-shaped steel 10 via the upper end side vertical member attachment fitting 61.

That is, when suspending the vertical members 70, 70 ..., The fitting ports 61b, 61b having a U-shaped cross section of the square box-shaped vertical member mounting bracket main body 61a are H. It is fitted to the mounting edge 60a on the front side of the shaped steel 60, the fastening bolt 61c is inserted and screwed downward in the orthogonal direction, and the upper surface of the mounting edge 60a of the H-shaped steel 60 is at the tip of the fastening bolt 61c. By pressing the side and joining the upper surface of the lower side of the fitting ports 61b and 61b and the lower surface of the mounting edge 60a of the H-shaped steel 60 via the tip of the fastening bolt 61c and fastening and integrating them with each other, the width is widened. It is securely fixed in a square area.

As described above, the vertical member mounting bracket main body 61a has a box-shaped structure having a predetermined width in the front-rear and left-right directions, and has U-shaped fitting ports 61b and 61b having a predetermined depth on both sides thereof. When it is fitted and fixed (jointly fixed) to the mounting edge 60a of the H-shaped steel 60, it is compared with the case of the engagement with the conventional hook structure and the suspension structure with the rod shaft. The joint surface of the mounting portion becomes much wider, the deformation rigidity of the vertical members 70, 70 ... in the direction orthogonal to the axis becomes higher, and the bearing capacity against a vertical load also becomes much larger.

Moreover, in the case of this embodiment, in addition to the above configuration, the auxiliary metal fitting 64 having substantially the same structure is further provided on the other side mounting edge portion 60a of the corresponding H-shaped steel 60.

As shown in FIGS. 3 and 12, the auxiliary metal fitting 64 also has a square box-shaped auxiliary metal fitting main body 64a (a rectangular parallelepiped shape in which the entire front side is open) and the front side (front side) of the square box-shaped auxiliary metal fitting main body 64a. Fitting ports 64b, 64b having a U-shaped cross section having a predetermined depth in the front-rear direction opened in the mounting edge 60a side of the H-shaped steel 60) and the central portions of the fitting ports 64b, 64b having a U-shaped cross section in the front-rear direction. It is located on the upper wall surface and is provided from the upper side to the lower side, and is inserted and screwed from the upper side to the lower side at the time of installation. It is composed of fastening bolts 64c that are fixed to the mounting edge 60a, and the fitting ports 64b and 64b having a U-shaped cross section are rear sides of the left and right side walls of the front opening of the auxiliary metal fitting body 64a. It is formed by notching to a predetermined depth.

Then, the vertical material mounting bracket 61 and the auxiliary bracket 64 are connected to each other by two left and right connecting rods 66, 66 in a state where the fitting ports 61b, 61b and 64b, 64b are opposed to each other in the same horizontal plane direction. It is designed to be firmly connected in a tensile state.

That is, in the actual mounting state, the auxiliary metal fitting 64 is also fitted and fixed to the mounting edge portion 60a on the other end side of the H-shaped steel 60 in the same manner as the vertical member mounting metal fitting 61, and then two of the two are fitted to each other. It is connected and fixed (tensile fixed) with the connecting rods 66 and 66 of.

Therefore, in the connected and fixed state of FIGS. 3 and 12, the vertical members 70, 70 ... at the upper ends of the horizontal reinforcing members 3, 3 ..., 3, 3 ... (and the ceiling frame 1) are suspended. Is securely pulled and fixed in the fitting direction by the auxiliary metal fitting 64, and even if an external force acts on the vertical material mounting metal fitting 61 in the non-fitting direction, the steel does not come off, and further, the H-shaped steel Since the mounting edges 60a and 60a are fitted and fixed in the opposite directions at two locations on both ends, the fitting state itself is further strengthened.

For example, in the case of the same configuration, as shown in FIG. 12, if a force in the direction of the horizontal arrow A1 acts on the vertical members 70, 70 ..., The fitting portion of the vertical member mounting bracket 61 is used. A pressing force in the direction of arrow A2 acts on the mounting edge 60a of the H-shaped steel 60, and a tensile force in the direction of arrow A3 acts on the connecting rods 66 and 66.

However, since the mounting edge portion 60a of the H-shaped steel 60 has high support rigidity, it does not move, and a large tensile force A3 acts on the connecting rods 66 and 66 portions. Therefore, if there is no auxiliary metal fitting 64 and there are no connecting rods 66 and 66, it is conceivable that the fitting state of the fitting portion of the vertical material mounting metal fitting 61 deteriorates and the fitting state may come off depending on the case. ..

However, as described above, two sets of metal fittings, the vertical material mounting metal fitting 61 and the auxiliary metal fitting 64, are fitted and fixed at two places, and the two connecting rods 66 are placed with a predetermined width on the left and right sides. , 66, the auxiliary metal fitting 64 and the connecting rods 66, 66 can surely prevent the deformation of the fitting portion due to the large tensile force A3, so that a more reliable fitting state can be maintained. Become. As a result, the movement of the vertical members 70, 70 ... In the A1 direction is also suppressed.

On the other hand, on the contrary, assuming that a force in the horizontal arrow B1 direction acts on the vertical members 70, 70 ..., The H-shaped steel 60 passes through the fitting portion of the vertical member mounting bracket 61. A tensile force in the direction of arrow B2 acts on the mounting edge portion 60a of the above, and a pressing force in the direction of arrow B3 acts on the connecting rods 66 and 66.

However, since the mounting edge portion 60a of the H-shaped steel 60 has high support rigidity, it does not move, and a large pressing force B3 acts on the connecting rods 66 and 66 portions. Therefore, if the auxiliary metal fitting 64 and the connecting rods 66, 66 are not provided, it is conceivable that the fitting state of the fitting portion of the vertical material mounting metal fitting 61 deteriorates, and the fitting state may be disengaged depending on the case. ..

However, as described above, two sets of metal fittings, the vertical material mounting metal fitting 61 and the auxiliary metal fitting 64, are fitted and fixed at two places, and the two connecting rods 66 are placed with a predetermined width on the left and right sides. , 66, the large pressing force B3 is blocked by the connecting rods 66, 66 and the auxiliary metal fitting 64, so that the fitting portion is prevented from being deformed by the pressing force B3, and the fitting state is assured. Will be able to maintain. As a result, the movement of the vertical material 70 in the B1 direction is also suppressed.

As a result, the plurality of vertical members 70, 70 ... themselves are less likely to sway, and the ceiling base side (horizontal reinforcing members 3, 3 ... hanging side) from which the ceiling frame is suspended has seismic resistance. Greatly improved.

In such a case, any surface may be welded, which facilitates the welding operation.

<About the hanging structure of the ceiling frame according to the thirteenth embodiment of the present invention: see FIGS. 47 to 54>
Next, FIGS. 47 to 54 show a suspended structure of the ceiling frame according to the thirteenth embodiment of the present invention.

In the configuration of this embodiment, for example, as shown in FIGS. 47 to 54, the same lip channel steel as in the second embodiment is adopted as the horizontal reinforcing member 3 in the X direction in the above-mentioned ceiling frame mounting structure. With respect to the ribs 3a and 3a surfaces on the opening side, the ceiling frame hanging member 10 made of the above-mentioned square steel using the mounting bracket 11 (see FIGS. 44 to 46) having the configuration of the above embodiment 12 The upper end portion 10a is attached, and the ceiling frame side field edge receiver is used with the connecting metal fittings 14 and 15 having the function of adjusting the attachment height position of the ceiling frame with respect to the lower end portion 10b of the ceiling frame hanging member 10. It is characterized in that it is attached to 6.

Since the mounting structure of the upper end portion 10a of the ceiling frame suspending member 10 using the mounting bracket 11 for the horizontal reinforcing member 3 is the same as that of the above-described embodiment 12, the same reference numerals are given to the portions having the same configuration. Therefore, the description thereof will be omitted. Further, since the connection structure of the ceiling frame side field edge 7 with the field edge receiver 6 is the same as in the case of each of the above-described embodiments, the description thereof will be omitted by adding the same reference numerals to the parts having the same configuration. ..

The connecting metal fittings 14 and 15 having the function of adjusting the mounting height position of the ceiling frame in this embodiment are the front surface of the lower end portion 10b of the ceiling frame hanging member 10 (on the side opposite to the surface mounted on the field edge receiver 6). The first metal fitting (first connecting metal fitting unit) 14 attached to the surface) and the second metal fitting 14 attached to the lower end portion 10b of the ceiling frame hanging member 10 and the field edge receiver 6 via the first metal fitting 14. A metal fitting (second connecting metal fitting unit) 15 and a connecting bolt 16 that connects the second metal fitting 15 to the first metal fitting 14 in a height-adjustable state that can move up and down and a fixed state that cannot move up and down. , The drill screws 12 and 12 for screwing and fixing the first metal fitting 14 to the lower end 10b of the ceiling frame hanging member 10 and the second metal fitting 15 are screwed to the lower end 10b of the ceiling frame hanging material 10. It is composed of drill screws 12 and 12 for fixing and drill screws 12 and 12 for screwing and fixing the second metal fitting 15 to the ceiling frame side field edge receiver 6.

The first metal fitting 14 has a vertically long groove-shaped bolt mounting portion 14a, a long hole (slot) 14c formed in the central portion of the bolt mounting portion 14a extending in the vertical direction, and both sides of the bolt mounting portion 14a. A metal having a hat-shaped cross section as a whole, which is provided with flange-shaped fixing portions 14c and 14c integrally formed with the metal and drill screw insertion holes 14d and 14d provided at the center of the flange-shaped fixing portions 14c and 14c. It consists of a board.

Then, in the first metal fitting 14, the bolt shaft portion protrudes toward the front side from the elongated hole 14b with respect to the groove-shaped bolt mounting portion (groove portion having a U-shaped cross section) 14a, and the head portion is inside the groove portion. The connecting bolt 16 is mounted and supported in a state where it fits in. Next, with the connecting bolt 16 supported, the flange-shaped fixing portions 14c and 14c are aligned (upper and lower and left and right) with respect to the front surface (mounting surface) of the lower end portion 10b of the ceiling frame suspending member 10. Then, by screwing the drill screws 12 and 12 into the lower end portion 10b of the ceiling frame hanging member 10 through the drill screw insertion holes 14d and 14d, the ceiling frame hanging member 10 It is securely fixed and attached to the front of the lower end portion 10b of the.

In this case, the lower end surface of the first metal fitting 14 is aligned with the front surface (mounting surface) of the lower end portion 10b of the ceiling frame hanging member 10 of the flange-shaped fixing portions 14c and 14c. It is performed so as to coincide with the lower end surface of 10 and both side surfaces of the flange-shaped fixing portions 14c and 14c coincide with both side surfaces of the ceiling frame suspending member 10. That is, the left-right width dimension of the first metal fitting 14 is formed to be equal to the left-right width dimension of the ceiling frame suspending member 10.

Further, the groove portion of the bolt mounting portion 14a is formed slightly deeper than the thickness dimension of the bolt head of the connecting bolt 16 with respect to the lower end portion 10b of the ceiling frame suspending member 10 of the first metal fitting 14. Even in the fixed state, the bolt 16 itself can be slid up and down via the bolt shaft. This point also applies to the relationship between the width dimension of the elongated hole 14b and the diameter of the bolt shaft.

On the other hand, the second metal fitting 15 is made of a metal plate as a whole, and has a first fitting portion 15a with respect to the U-shaped ceiling frame hanging member 10 in a plan view and a U-shaped portion base of the first fitting portion 15a. The second slot 15b formed on the end face, the drill screw insertion holes 15c and 15c formed in the central portions of the left and right side walls of the first fitting portion 15a, and the drill screw insertion holes 15c, The drill screws 12 and 12 inserted through the 15c and the side view U-shaped top frame (the field edge receiver 6 thereof) are integrally provided outside the tips of the left and right side walls of the first fitting portion 15a. , The second fitting portions 15d, 15d, the drill screw insertion holes 15c, 15c formed in the center of the base end surface of the U-shaped portion of the second fitting portions 15d, 15d, and the drill screw insertion holes 15c, It consists of drill screws 12 and 12 that are inserted through 15c. The first U-shaped fitting portion 15a in a plan view is fitted to the lower end portion 10b of the ceiling frame suspending member 10 made of the square steel pipe, and the second fitting portion 15a in a U-shape in a side view is U-shaped. The joint portions 15d and 15d are fitted to the field edge receiver 6 of the ceiling frame made of the channel steel.

The first fitting portion 15a of the second metal fitting 15 is fitted to the lower end portion 10b of the ceiling frame suspending member 10 made of the square steel tube, and the first metal fitting 14 and the first metal fitting 14 are used. It is fitted via the connecting bolt 16 mounted on the bolt mounting portion 14a of the above, and after fitting, it is connected by the connecting bolt 16 and finally fastened and fixed via the washer 16a and the nut 16b. Until then, it slides freely in the vertical direction through the first slot 14b of the first bracket 14 and the second slot 15b of the second bracket 15 to adjust to a predetermined height position. It is possible to do.

That is, as described above, the depth of the groove portion of the bolt mounting portion 14a of the first metal fitting 14 is formed to be slightly deeper than the thickness dimension of the bolt head of the connecting bolt 16, and the first metal fitting 14 Even in the fixed state of the ceiling frame suspending member 10 with respect to the lower end portion 10b, the connecting bolt 16 itself can be slid up and down using a bolt shaft according to the length of the elongated hole 14b in the vertical direction. This point is the same as the relationship between the width dimension of the elongated hole 14b and the diameter of the bolt shaft, and the bolt shaft of the connecting bolt 16 is loosely fitted with a gap that allows it to slide to the left and right, whereby the connecting bolt 16 is loosely fitted. Can be slid up and down.

Then, the first fitting portion 15a of the second metal fitting 15 that attaches the lower end portion 10b of the ceiling frame hanging member 10 to the field edge receiver 6 fits into the lower end portion 10b of the ceiling frame hanging member 10 when the first fitting portion 15a is attached. At the time of fitting, it is first supported by the first metal fitting 14 side fixed to the lower end portion 10b side of the ceiling frame hanging member 10, and is held in a slidable state in the vertical direction as described above. The tip side bolt shaft (the bolt shaft portion protruding from the elongated hole 14b) of the connecting bolt 16 penetrates the second elongated hole 15b on the base end surface of the U-shaped portion, and on the protruding end side of the second elongated hole 15b. The nut 16c is fastened and fixed by screwing the nut 16c via a washer 16b having a diameter larger than the diameter of the second elongated hole 15b. In this case, the length of the left and right side wall portions of the first fitting portion 15a of the second mounting bracket 15 is, of course, the height dimension of the bolt mounting portion 14a of the first mounting bracket 14. The fitting portions 15d and 15d of No. 2 are formed to have a length that allows them to be accurately fitted to the field edge receiver 6. Further, as for the length relationship between the first elongated hole 14b on the first mounting bracket 14 side and the second elongated hole 15b on the second mounting bracket 15 side, the length of the first elongated hole 14b is better. It is formed to be much longer, and the length of the second elongated hole 15b is formed to be as short as about twice the diameter of the bolt shaft of the connecting bolt 16. Basically, the height of the ceiling frame hanging member 10 when the ceiling frame is attached (when the field edge receiver 6 is attached) is adjusted by the first elongated hole 14b, but only by the first elongated hole 14b. This is because the adjustment dimension is replenished when the adjustment dimension is insufficient, or the fine level adjustment by operating only the second mounting bracket 15 when finally fixing is performed by using the second elongated hole 15b.

According to such a configuration, for example, with respect to the lower end portion 10b of the vertical ceiling frame suspending material (square steel pipe) 10 firmly attached to the horizontal reinforcing member 3 which is the ceiling frame mounting member via the mounting bracket 11. When attaching the ceiling frame, the first metal fitting 15 is moved up and down with respect to the first metal fitting 14 (that is, the ceiling frame hanging member 10) via the connecting bolt 16 as follows. After adjusting the mounting height using the length of the elongated hole 14b (and the second elongated hole 15b), it is finally fixed to the lower end 10b of the ceiling frame hanging member 10 and of the ceiling frame. The second metal fitting 15 for fitting and fixing the field edge receiver 6 portion can be accurately mounted at an appropriate mounting height position. As a result, even if the field edge receiver of the ceiling frame is bent due to a load, it can be mounted horizontally with the correction.

In the attachment of the ceiling frame to the ceiling frame hanging member 10 in this embodiment, for example, as shown in FIG. 47, the end portion of the lower end portion 10b of the ceiling frame hanging member 10 is used as the attachment position (reference line). First, the first metal fitting 14 of the connecting metal fitting unit is accurately attached to the same end portion.

The attachment of the first metal fitting 14 to the end of the lower end 10b of the ceiling frame hanging member 10 coincides with, for example, the lower end line of the first metal fitting 14 coincides with the lower end surface line of the lower end 10b of the ceiling frame hanging member 10. With the lines on both sides of the left and right flange-shaped fixing portions 14c and 14c aligned with the lines on both left and right sides of the ceiling frame suspending member 10, the drill screws 12 and 14d are passed through the drill screw insertion holes 14d and 14d. It is realized by screwing 12 into the lower end portion 10b of the ceiling frame suspension member 10. When the lower end surface line and the left and right side surface lines of the first metal fitting 14 are aligned with the lower end surface line and the left and right side surface lines of the lower end portion 10b of the ceiling frame hanging member 10 in this way, basically the first The entire metal fitting 14 is coaxially attached to the lower end 10b of the ceiling frame hanging member 10, and the first elongated hole 14 also extends in the vertical direction coaxial with the lower end 10b of the ceiling frame hanging member 10. become.

Then, when the first elongated hole 14b is attached in a state of being inclined with respect to the ceiling frame hanging member 10 in this way, the second metal fitting 15 fitted to the ceiling frame hanging member 10 is smoothly moved in the vertical direction. There is a problem that the height cannot be adjusted properly without sliding.

Further, in this way, the flat flange-shaped fixing portions 14c and 14c of the first metal fitting 14 are overlapped on the flat wall surface of the ceiling frame suspension member 10 by aligning the lower end surfaces and the side surfaces, and accurately pressed by hand. It is not easy to screw the drill screws 12 and 12 into the correct position, and the position shift is likely to occur due to the rotational force and vibration when the drill screw is screwed.

This embodiment is made to solve such a problem, and as shown in FIGS. 55 and 56, for example, the first embodiment has the same configuration as the first metal fitting 14 of the thirteenth embodiment. The length of the metal fitting 14 in the vertical direction is increased by a predetermined dimension, and the fitting claws (holding ribs) 14e that are fitted to the left and right sides of the ceiling frame hanging material (square steel pipe) 10 on the left and right sides of the upper and lower ends thereof. , 14e, 14e, 14e are provided.

In this case, the fitting claws (holding ribs) 14e, 14e, 14e, 14e are formed by extending a part of the flange-shaped fixing portions 14c, 14c on both sides of the bolt mounting portion 14a to the left and right sides and bending them at a right angle. However, if possible, bend it slightly narrower than 90 degrees so as to exert a certain holding force (binding force), or a small protrusion that exerts a reliable engaging force on the tip side fitting surface or the entire fitting surface. It is preferable to provide a portion.

With such a configuration, when the first metal fitting 14 is attached to the ceiling frame suspending member 10, the fitting force of the fitting claws (holding ribs) 14e, 14e, 14e, 14e is used to use the fitting force of the fitting claws (holding ribs) 14e, 14e, 14e, 14e to the ceiling. As long as the first metal fitting 14 is fitted to the frame hanging member 10, the fitting claws 14e, 14e, 14e, 14e are fitted, and the fitting claws 14e, 14e, 14e, 14e are surely attached along the ceiling frame hanging member 10. In the same attached state, the position of the lower end surface can be easily and surely aligned by simply hitting the first metal fitting 14 portion from the upper side with some kind of receiving surface member on the lower end surface side.

Since the drill screws 12 and 12 may be screwed in the temporarily fixed state by the same fitting, the drill screws 12 and 12 can be easily screwed and the misalignment at the time of screwing is unlikely to occur.

Therefore, not only is it possible to accurately position and hold the first metal fitting 14, which is the basis for attaching the second metal fitting 15 so that the height can be adjusted, but also, as in the thirteenth embodiment, the first metal fitting 14 Compared to the case where the flange-shaped fixing portions 14c and 14c of No. 1 are overlapped with the lower end surfaces aligned and screwed with the drill screws 12 and 12 while being held by hand, the mounting work efficiency at the time of mounting the first metal fitting 14 is much better. Become.

Further, in the case of such a configuration, for example, as is clear from the configuration of FIG. 56, the pair of fitting claws 14e, 14e, 14e, 14e on the upper and lower ends on the left and right sides are the second fitting claws 14e, 14e, 14e, 14e when the second metal fitting 15 is fitted. Since the function of positioning the fitting portion with respect to the metal fitting 14 of 1 and the fitting guide function are performed, the operation of fitting the second metal fitting 15 with respect to the first metal fitting 14 is also reliable and easy.

As a result, in the case of the above configuration, in addition to accurate and easy positioning and mounting of the first metal fitting 14 at the time of mounting, positioning and mounting of the second metal fitting 15 at the time of mounting are also accurate and easy. This enables more accurate and reliable installation of the ceiling frame.

Regarding the adjustment of the height position, for example, as shown in FIG. 56, the pair of fitting claws (holding ribs) 14e, 14e, 14e, 14e on the upper and lower ends of the first metal fitting 14 are respectively. The first and second fitting portions 15a and 15d of the second metal fitting 15 so that the heights of the upper and lower intervals (spans) b and b can be adjusted in the same manner as in FIGS. 52 to 54 of the above-described embodiment. The length of the first slotted hole 14b in the first metal fitting 14 in the vertical direction is sufficiently long, for example, as shown in FIGS. 57 to 59. A second frame is attached by moving the connecting bolt 16 to the upper limit position, the intermediate position, and the lower limit position of the first slotted hole and fixing the connecting bolt 16 as in the case of the above-mentioned (1) to (3) of the first slot. The metal fitting 15 can be fixed at a desired height position.

In this case, the vertical width c of the pair of fitting claws (holding ribs) 14e, 14e, 14e, 14e on the upper and lower ends of the first metal fitting 14 is considered to maintain and strengthen the fitting force at the time of fitting. Is formed to the appropriate dimensions. Further, even if the bending angle is slightly smaller than 90 degrees, since a rounded surface having a predetermined curvature is formed at the corner of the square steel pipe constituting the ceiling frame suspension member 10, the fitting work is performed. The work is very easy.

<About the hanging structure of the ceiling frame according to the fifteenth embodiment of the present invention: see FIGS. 60 and 61>
Next, FIGS. 60 and 61 show a suspended structure of the ceiling frame according to the fifteenth embodiment of the present invention.

The ceiling frame connecting metal fittings (connecting metal fitting units) 14 and 15 in the ceiling frame hanging structure according to the fourteenth embodiment can be securely mounted in parallel to the ceiling frame hanging member 10 in a coaxial state. The positioning is accurate, the stability after mounting is high, and the position does not shift even when the drill screw is screwed. Then, if the length in the vertical direction is increased, a sufficient span length can be secured.

However, in the case of the same configuration, the adjustment position of the ceiling frame suspending member 10 to the lower limit side is regulated by the fitting claws 14e and 14e on the lower end side of the first metal fitting 14, so that the figure in the thirteenth embodiment is shown. As can be seen by comparing 54 with FIG. 59 in the 14th embodiment, free position adjustment to the lower end side as in FIG. 54 in the 13th embodiment cannot be performed, and the lower limit side of the adjustment position cannot be performed. There is a problem that the lower end of the ceiling frame suspending member 10 protrudes downward by a predetermined dimension.

Therefore, in order to solve such a problem, in this embodiment, for example, as shown in FIG. 60, the fitting claws 14e, 14e on the lower end side of the first metal fitting 14 in the connecting metal fitting unit are eliminated. It is characterized in that it is fitted to the ceiling frame hanging member 10 only by the fitting claws 14e and 14e on the left and right on the upper end side.

With such a configuration, the problem that the adjustment position of the ceiling frame hanging member 10 to the lower limit side is restricted by the fitting claws 14e and 14e on the lower end side can be surely solved. For example, FIG. 60 As shown in FIG. 13, as in the case of FIG. 54 in the thirteenth embodiment, the adjustment can be set at a position lower than the lower end of the ceiling frame suspending member 10 with a margin.

Moreover, in the case of this embodiment, the first metal fitting 14 is securely fixed to the ceiling frame suspending member 10 by at least the fitting claws 14e and 14e on both the left and right sides on the upper end side, and the left and right sides on both the upper and lower ends. Since it is possible to maintain a stable positioning and mounting state in substantially the same manner as when the fitting claws 14e, 14e, 14e, 14e are provided in, no misalignment occurs even when the drill screws 12 and 12 are screwed.

In this case, in order to increase the fitting force and positioning stability of the fitting claws 14e and 14e on the ceiling frame suspending member 10, the vertical width c of the fitting claws 14e and 14e is increased as necessary. The configuration is adopted.

<About the hanging structure of the ceiling frame according to the 16th embodiment of the present invention: see FIGS. 62 to 65>
Next, FIGS. 62 to 65 show a suspended structure of the ceiling frame according to the 16th embodiment of the present invention.

In the case of the configuration of the first metal fitting 14 of the ceiling frame connecting metal fitting (connecting metal fitting unit) in the ceiling frame suspension structure according to the fifteenth embodiment, since there are no fitting claws 14e and 14e on both the left and right sides on the lower end side, the above implementation is performed. The adjustment position of the ceiling frame hanging member 10 to the lower limit side is the first metal fitting 14 like the first metal fitting 14 of the ceiling frame connecting metal fitting (connecting metal fitting unit) in the ceiling frame hanging structure according to the first embodiment. The ceiling frame suspending material can be freely adjusted to the lower end side as shown in FIG. 54 in the above embodiment 13 without being restricted by the fitting claws 14e and 14e on both the left and right sides of the lower end side. The lower end of 10 does not protrude downward.

However, it is undeniable that the positioning and temporary fixing functions on the lower end side are deteriorated by the amount of the fitting claws 14e and 14e on both the left and right sides on the lower end side, and the position shift at the time of screwing the drill screw is likely to occur.

Therefore, in this embodiment, in order to solve such a problem and facilitate the alignment with the lower end surface of the ceiling suspension member 10, a fitting claw is also provided on the lower end side of the first metal fitting 14. However, the claws are provided on the left and right sides of the lower end surface of the first metal fitting 14 instead of on the left and right sides of the lower end portion as in the 14th embodiment.

That is, in this embodiment, the fitting claws fitted to the ceiling frame hanging member 10 provided on the metal fitting body of the first metal fitting 14 are located on both sides of the upper end portion of the first metal fitting 14. The first fitting claws 14e and 14e fitted on both the left and right sides of the ceiling frame hanging member 10 and the first metal fitting of the ceiling frame hanging member 10 on the left and right sides of the lower end end surface of the first metal fitting 14. It is composed of second fitting claws 14f and 14f that are abutted and engaged with each other on the left and right sides of the lower end surface of the mounting surface.

In this case, the first fitting claws 14e and 14e and the second fitting claws 14f and 14f are formed by bending a part of the metal fitting body of the first metal fitting 14 toward the ceiling frame hanging member 10 side by 90 degrees, respectively. Has been done.

According to such a configuration, when fixing the first metal fitting 14 to the lower end portion 10b of the ceiling frame suspending member 10, the second fitting claws 14f and 14f on the lower end portion end surface of the first metal fitting 14 are attached to the ceiling frame. By abutting and engaging with the lower end end surface of the first metal fitting mounting surface of the hanging member 10, the mounting position in the vertical direction is determined, and the first fitting claws on both sides of the upper end portion of the first metal fitting 14 are determined. By fitting the 14e and 14e to both sides of the ceiling frame suspending member 10, the mounting position in the left-right direction can be determined and the whole can be temporarily fixed. That is, according to the same configuration, it is possible to accurately position each of the upper, lower, left, and right mounting positions, securely temporarily fix the mounting position, and then fix the mounting position with a drill screw.

As a result, even if the operator does not support it by hand, it is surely held in the positioned state, and even if the drill screw is screwed, it can be accurately fixed without any misalignment.

Therefore, not only the workability when fixing the first metal fitting 14 to the ceiling frame suspending member 10 is improved, but also the ceiling via the first metal fitting 14 of the second metal fitting 15 for fitting and fixing the ceiling frame. The attachment position to the frame hanging member 10 can be easily adjusted, and the accuracy of attaching the ceiling frame to the ceiling frame hanging member 10 is also improved.

<About the configuration of the modified example>
In this case, the second fitting claws 14f, 14f which are on the left and right of the lower end end surface of the first metal fitting 14 and are in contact with the left and right of the lower end surface of the first metal fitting mounting surface of the ceiling frame hanging member 10. As described above, a part of the flange-shaped fixing portions 14c and 14c lower end portions of the first metal fitting 14 may be bent by 90 degrees, but as shown in FIGS. 66 and 67, for example, the 90 The tip of the bent piece is bent 90 degrees to form a side view cono shape, and is engaged with the back side of the mounting surface of the lower end portion 10b of the ceiling frame hanging member 10. But it's okay.

With such a configuration, the positioning and fixing state of the first metal fitting 14 with respect to the ceiling frame suspending member 10 becomes more reliable, and the position is less likely to shift even when the drill screw is screwed.
