The dimension of the first connecting member 10 in the longitudinal direction (X direction) is larger than the dimension in the left-right direction of the ceiling suspension object 100, and both left and right ends project further in the left-right direction than the left and right side surfaces of the ceiling suspension object 100. , It is extended to a position above the mounting piece 110.

The first connecting member 10 has an insertion portion 12 for inserting the coupling members 20 and 21, an insertion portion 13 for inserting the bolt member 50, and an insertion portion for inserting the suspension bolt 9 at both left and right ends thereof. It has a part 14. The insertion portion 12 is formed in the vertical plate portion 10b of the first connecting member 10. Further, the insertion portions 13 and 14 are formed in the flat plate portion 10a of the first connecting member 10. These insertion portions 12, 13 and 14 are formed as, for example, round holes. However, the insertion portions 12, 13 and 14 are not limited to the round holes, and may be formed as, for example, U-shaped notches. The insertion portion 14 functions as an attachment portion 14a for attaching the lower portion of the suspension bolt 9 that supports the ceiling suspension object 100 in a suspended state from the ceiling structure.

Further, the second connecting member 11 is made of, for example, L-shaped angle steel (angle steel) like the first connecting member 10, and is formed on a flat plate portion 11a parallel to the upper surface of the ceiling suspension 100 and a flat plate portion 11a. It has a vertical plate portion 11b forming a right angle to the vertical plate portion 11b, and has high rigidity. The second connecting member 11 is arranged parallel to the first connecting member 10 at a position separated from the first connecting member 10 by a predetermined distance at the upper surface position of the ceiling suspension object 100. Like the first connecting member 10, the second connecting member 11 is arranged along the left-right direction (X direction) of the ceiling hanging object 100, and the lower surface of the flat plate portion 11a contacts the upper surface of the ceiling hanging object 100. It is placed in the same state. The dimension of the second connecting member 11 in the longitudinal direction (X direction) is larger than the dimension in the left-right direction of the ceiling suspension object 100, and both left and right ends project further in the left-right direction than the left and right side surfaces of the ceiling suspension object 100. , It is extended to a position above the mounting piece 110.

In the present embodiment, a total of four bolt members 50 are attached to the left and right sides of the ceiling suspension 100. That is, the lower portion of the bolt member 50 is connected to each of the two mounting pieces 110 provided near the lower portion of the left side surface 103 of the ceiling suspension object 100. Further, the lower portion of the bolt member 50 is also connected to each of the two mounting pieces provided near the lower portion of the right side surface 104 of the ceiling suspension object 100. These four bolt members 50 are fixed to the mounting piece 110 by being tightened with the two nuts 73 and 73 sandwiching the mounting piece 110 with the lower portion thereof inserted into the mounting piece 110.

The vibration of the upper portion of the four bolt members 50 cannot be suppressed only by fixing the lower portion thereof to the mounting piece 110. Therefore, in the present embodiment, the upper portion of each bolt member 50 is fixed to the first connecting member 10 or the second connecting member 11 by the first fixing member 15 or the second fixing member 17. That is, the upper portion of the bolt member 50 is inserted into the insertion portion 13 of the first connecting member 10 or the second connecting member 11, and the first fixing member 15 or the second fixing member 17 is inserted in a portion protruding upward from the insertion portion 13. By being attached, it is fixed to the first connecting member 10 or the second connecting member 11. The first fixing member 15 and the second fixing member 17 are composed of nuts that can be attached to the bolt member 50, and are screwed with a male screw formed on the surface of the bolt member 50. The first fixing member 15 is attached to a bolt member 50 projecting upward from the flat plate portion 10a of the first connecting member 10. Then, the first fixing member 15 is fastened to the flat plate portion 10a of the first connecting member 10, so that the upper portion of the bolt member 50 is fixed to the first connecting member 10. Further, the second fixing member 17 is attached to the bolt member 50 projecting upward from the flat plate portion 11a of the second connecting member 11. Then, the second fixing member 17 is fastened to the flat plate portion 11a of the second connecting member 11, so that the upper portion of the bolt member 50 is fixed to the second connecting member 11. That is, the upper portions of the four bolt members 50 are fixed to the left and right ends of the first connecting member 10 and the second connecting member 11.

When the first fixing member 15 is tightened with respect to the flat plate portion 10a of the first connecting member 10, the first connecting member 10 receives an axial force from the bolt member 50. This axial force acts as a force that presses the first connecting member 10 against the upper surface of the ceiling suspension object 100. Therefore, the first connecting member 10 is fixed in a state of being in contact with the upper surface of the ceiling suspension object 100 by fastening the first fixing member 15 to the flat plate portion 10a. As a result, both the lower part and the upper part of the bolt member 50 can be fixed on the side surface of the ceiling suspension object 100, and the steady rest effect of the bolt member 50 is exhibited.

The same applies to the second connecting member 11. That is, when the second fixing member 17 is tightened with respect to the flat plate portion 11a of the second connecting member 11, the second connecting member 11 receives the axial force from the bolt member 50. This axial force acts as a force that presses the second connecting member 11 against the upper surface of the ceiling suspension object 100. Therefore, the second connecting member 11 is fixed in contact with the upper surface of the ceiling suspension object 100 by fastening the second fixing member 17 to the flat plate portion 11a. As a result, both the lower part and the upper part of the bolt member 50 can be fixed on the side surface of the ceiling suspension object 100, and the steady rest effect of the bolt member 50 is exhibited.

The coupling members 20 and 21 are composed of, for example, bolt members having male screws formed on their outer peripheral surfaces. The connecting members 20 and 21 are members that connect and integrate the first connecting member 10 and the second connecting member 11 located at predetermined intervals with each other in a parallel state. Such connecting members 20 and 21 are composed of, for example, bolt-shaped members, have a predetermined length in the front-rear direction (Y direction) of the ceiling suspension 100, and both ends thereof are the first connecting member 10 and the first connecting member 10. 2 It is connected to each of the connecting members 11. That is, the connecting members 20 and 21 are the first connecting members in a state where both ends are inserted into the vertical plate portion 10b of the first connecting member 10 and the insertion portion 12 formed in the vertical plate portion 11b of the second connecting member 11. It is fixed to 10 and the second connecting member 11. For example, two nuts 24 and 25 are mounted on both ends of the coupling member 20, and the two nuts 24 and 25 are attached to the vertical plate portion 10b of the first connecting member 10 and the vertical plate portion 11b of the second connecting member 11. It is tightened so as to sandwich each. Similarly, two nuts 26 and 27 are mounted on both ends of the coupling member 21, and these two nuts 26 and 27 are the vertical plate portion 10b of the first connecting member 10 and the vertical plate portion 11b of the second connecting member 11. It is tightened so as to sandwich it. In this way, the plurality of connecting members 20, 21 connect the first connecting member 10 and the second connecting member 11 to each other at different positions in the left-right direction of the ceiling suspension object 100, whereby the first connecting member 10 and the first connecting member 10 and the first connecting member 10 and the second connecting member 10 are connected to each other. The two connecting members 11 are integrated with each other in a state of being parallel to each other. Therefore, even if an earthquake occurs, the coupling members 20 and 21 can suppress the relative displacement and posture change between the first connecting member 10 and the second connecting member 11.

Further, the steady rest device 1 includes a first regulating member 30 and a second regulating member 40 in order to prevent the first connecting member 10 and the second connecting member 11 from skidding in the XY plane. The first regulating member 30 is a member that regulates the steady rest device 1 from being displaced relative to the ceiling suspension 100 in the left-right direction (X direction). The second regulating member 40 is a member that regulates the steady rest device 1 from being displaced relative to the ceiling suspension object 100 in the front-rear direction (Y direction) orthogonal to the left-right direction (X direction).

FIG. 3 is a diagram showing a configuration example of the first regulation member 30. The first regulating member 30 is a member installed at four locations on the left and right side surfaces of the ceiling suspension 100. For example, as shown in FIG. 3, the horizontal plate portion 31 and the vertical plate portion 32 form a right angle to each other. It is composed of an L-shaped metal member. The horizontal plate portion 31 is provided with an insertion portion 33 for inserting the bolt member 50. The insertion portion 33 is formed as a round hole slightly larger than the outer diameter of the bolt member 50, for example, as shown in FIG. However, the insertion portion 33 is not limited to the round hole, and may be formed as a notch portion in which the horizontal plate portion 31 is cut out in a U shape.

The first regulation member 30 is attached to the bolt member 50 with the bolt member 50 inserted through the insertion portion 33. For example, as shown in FIG. 2, the first regulating member 30 is attached to the bolt member 50 by supporting the lower surface side of the horizontal plate portion 31 by the nuts 16 and 18 mounted on the bolt member 50. For example, the first regulating member 30 provided on the lower surface side of the first connecting member 10 is supported by the nut 16. Further, the first regulating member 30 provided on the lower surface side of the second connecting member 11 is supported by the nut 18. The nuts 16 and 18 are tightened in a direction that pushes up the lower surface side of the horizontal plate portion 31 upward. Therefore, the first regulating member 30 is fixed in a state where the upper surface of the horizontal plate portion 31 is pressed against the lower surface of the first connecting member 10 or the second connecting member 11. Further, when the bolt member 50 is inserted through the insertion portion 33 of the horizontal plate portion 31, the vertical plate portion 32 is in a state of being joined to the left side surface 103 or the right side surface 104 of the ceiling suspension object 100. Therefore, when the horizontal plate portion 31 is fixed to the bolt member 50, the vertical plate portion 32 presses the left side surface 103 or the right side surface 104 of the ceiling suspension object 100.

Such a first regulating member 30 is attached to a total of four locations on the left and right side surfaces 103 and 104 of the ceiling suspension 100. The four first regulating members 30 maintain a constant distance between the ceiling suspension 100 and the bolt member 50. Therefore, the first regulating member 30 can regulate the steady rest device 1 from being displaced relative to the ceiling suspension 100 in the left-right direction (X direction).

In the above, the case where the upper surface of the horizontal plate portion 31 of the first regulating member 30 is fixed in a state of being pressed against the lower surface of the first connecting member 10 or the second connecting member 11 has been illustrated, but the case is limited to this. It's not a thing. That is, the first regulating member 30 can be attached to an arbitrary height position of the bolt member 50.

FIG. 4 is a diagram showing a configuration example of the second regulating member 40. The second regulating member 40 is a member installed at a total of four locations, the front surface 101 and the back surface 102 of the ceiling suspension object 100. For example, as shown in FIG. 4, the vertical plate portion 41, the horizontal plate portion 42, and the vertical plate portion It is composed of a substantially Z-shaped metal member having 43, the vertical plate portion 41 and the horizontal plate portion 42 forming a right angle to each other, and the horizontal plate portion 42 and the vertical plate portion 43 forming a right angle to each other. .. The vertical plate portion 41 is provided with an insertion portion 44 for inserting the coupling members 20 and 21. The insertion portion 44 is formed as a round hole slightly larger than the outer diameter of the connecting members 20 and 21 configured as bolt members, for example, as shown in FIG. However, the insertion portion 44 is not limited to the round hole, and may be formed as a notch portion in which the vertical plate portion 41 is cut out in a U shape.

As shown in FIG. 2, the second regulating member 40 is attached to the vertical plate portion 10b of the first connecting member 10 or the vertical plate portion 11b of the second connecting member 11, and the first connecting member 10 or the second connecting member 40 is connected. It is fixed to the member 11. Specifically, the position of the insertion portion 44 of the second regulating member 40 in a state where the vertical plate portion 41 is joined to the vertical plate portion 10b of the first connecting member 10 or the vertical plate portion 11b of the second connecting member 11. The vertical plate portion 41 is first connected by aligning the position of the insertion portion 12 with the position of the insertion portion 12, inserting the tips of the coupling members 20 and 21 into the insertion portions 12, 44 and tightening the two nuts 24 and 25. It is fixed to the vertical plate portions 10b and 11b of the member 10 or the second connecting member 11.

The length L (see FIG. 4) of the horizontal plate portion 42 connecting the two vertical plate portions 41 and 43 is such that the vertical plate portion 43 bent downward is engaged with the upper end portion of the front surface 101 or the back surface 102 of the ceiling suspension object 100. It is adjusted in advance according to the size of the ceiling suspension 100 so that it can be fitted. For example, in the case of the second regulating member 40 fixed to the vertical plate portion 10b of the first connecting member 10, the length L of the horizontal plate portion 42 is from the vertical plate portion 10b of the first connecting member 10 to the ceiling suspension object 100. It is formed to have a length similar to the length up to the back surface 102. Further, in the case of the second regulating member 40 fixed to the vertical plate portion 11b of the second connecting member 11, the length L of the horizontal plate portion 42 is the ceiling suspension object 100 from the vertical plate portion 11b of the second connecting member 11. It is formed to have the same length as the length up to the front 101. Therefore, of the four second regulating members 40 provided in the steady rest device 1, the two second regulating members 40 fixed to the first connecting member 10 and the other two fixed to the second connecting member 11 The length L of the horizontal plate portion 42 may be different from that of the second regulating member 40.

When the second regulating member 40 is fixed to the first connecting member 10 or the second connecting member 11, the vertical plate portion 43 is in a state of being engaged with the upper end portion of the front surface 101 or the back surface 102 of the ceiling suspension object 100. It is possible to regulate that the steady rest device 1 is displaced relative to the ceiling suspension 100 in the front-rear direction (Y direction).

In this way, the first regulating member 30 and the second regulating member 40 regulate the steady rest device 1 from being displaced relative to the ceiling suspension object 100 in the X direction and the Y direction, and suspend the steady rest device 1 from the ceiling. It can be fixed in a state of being positioned on the lowered object 100.

Further, anti-vibration members 60 are attached in advance to the insertion portions 14 for attaching the suspension bolts 9 at both ends of the first connecting member 10 and the second connecting member 11. FIG. 5 is a diagram showing an example of the anti-vibration member 60. The anti-vibration member 60 includes an elastic member 62 made of a metal coil spring or the like, a mounting portion 61 provided on the upper portion of the elastic member 62, and a ring member 67 provided on the lower portion of the elastic member 62. .. The mounting portion 61 is formed of a material having flexibility and elasticity such as rubber. Similarly, the ring member 67 is also formed of a material having flexibility and elasticity such as rubber. The mounting portion 61 is supported in a state where the upper portion of the elastic member 62 is fitted, and is mounted on the insertion portion 14 of the first connecting member 10 or the second connecting member 11. The mounting portion 61 is a substantially cylindrical member, and has an umbrella-like shape so that the upper portion 63 can be easily fitted into the insertion portion 14, and the lower portion 64 has a ring shape that engages with the lower surface of the insertion portion 14. It has become. Further, an annular groove 65 for fitting into the insertion portion 14 is formed between the upper portion 63 and the lower portion 64. The mounting portion 61 is provided with a hole 66 that penetrates the central portion vertically. The inner diameter of the hole 66 is formed as a diameter slightly larger than the outer diameter of the hanging bolt 9. Further, the ring member 67 is attached to the elastic member 62 with the lower portion of the elastic member 62 fitted therein. A hole through which the suspension bolt 9 can be inserted is formed in the center of the ring member 67.

As shown in FIG. 2, the vibration-proof member 60 as described above is a first connecting member in a state where the mounting portion 61 is mounted on the insertion portions 14 provided at both ends of the first connecting member 10 or the second connecting member 11. It is attached to the 10 or the second connecting member 11. The lower end of the suspension bolt 9 is inserted into the vibration isolator member 60, and the washer 76 and the nut 77 are attached to the portion protruding downward of the vibration isolator member 60 to be attached to the steady rest device 1. Since the lower part of the hanging bolt 9 is attached to the steady rest device 1 via the vibration isolator member 60, even if the ceiling hanging object 100 vibrates during operation, the vibration is not transmitted to the hanging bolt 9. That is, the anti-vibration member 60 has a function of suppressing the vibration of the ceiling suspension 100 from propagating to the suspension bolt 9. The steady rest device 1 is provided with this anti-vibration function, so that when the ceiling suspension object 100 is operating normally, the ceiling suspension object 1 is connected to a ceiling structure such as a ceiling slab to which the upper end portion of the suspension bolt 9 is connected. I try not to transmit 100 vibrations.

As described above, in the steady rest device 1 of the present embodiment, the lower portion of the bolt member 50 is fixed to the mounting pieces 110 provided on the left and right side surfaces of the ceiling suspension object 100, and the upper portion of the bolt member 50 is first. It is fixed to both ends of the connecting member 10 or the second connecting member 11. The first connecting member 10 is attached in a state where the first fixing member 15 attached to the bolt member 50 is tightened so that the axial force of the bolt member 50 acts to press the upper surface of the ceiling suspension object 100. Further, in the second connecting member 11, when the second fixing member 17 mounted on the bolt member 50 is tightened, the upper surface of the ceiling suspension 100 is subjected to the axial force of the bolt member 50 as in the case of the first connecting member 10. It is attached to the state of pressing. Therefore, the bolt members 50 attached to the left and right side surfaces of the ceiling suspension 100 are fixed in a state where an axial force is applied between the first connecting member 10 or the second connecting member 11 and the mounting piece 110. Therefore, it forms an integral structure with the ceiling hanging object 100. Therefore, even if an earthquake occurs, the steady rest device 1 can effectively prevent the bolt member 50 from swinging differently from the ceiling suspension object 100.

FIG. 6 is a front view showing a state in which the steady rest device 1 is attached to the ceiling suspension object 100. As shown in FIG. 6, in the steady rest device 1, both ends of the first connecting member 10 or the second connecting member 11 are anti-vibration members with respect to the lower parts of a plurality of hanging bolts 9 hanging from a ceiling structure such as a ceiling slab. It is attached via 60. Further, in the steady rest device 1, the lower surfaces of the first connecting member 10 and the second connecting member 11 are in close contact with the upper surface of the ceiling suspension object 100, and the axial force of the bolt member 50 causes the first connecting member 10 and the second connecting member 10 and the second connecting member. 11 is attached in a state where the upper surface of the ceiling suspension 100 is pressed. Therefore, the bolt member 50 attached to the mounting pieces 110 provided on the left and right side surfaces of the ceiling suspension object 100 does not displace relative to the ceiling suspension object 100 in the X direction. That is, the steady rest device 1 exerts the steady rest effect of the bolt member 50 connected to the mounting piece 110 of the ceiling suspension object 100. Further, as shown in FIG. 6, in the first regulating member 30 attached to the bolt member 50, since the vertical plate portion 32 is joined to the left and right side surfaces of the ceiling suspension object 100, the upper portion of the bolt member 50 is the ceiling. It prevents the suspended object 100 from being displaced relative to the left and right in the X direction. Therefore, the positions of the first connecting member 10 and the second connecting member 11 in the X direction are fixed on the upper surface of the ceiling hanging object 100, and even if a large-scale earthquake occurs, the upper surface of the ceiling hanging object 100 is fixed. It does not slide in the X direction.

FIG. 7 is a left side view showing a state in which the steady rest device 1 is attached to the ceiling suspension object 100. As shown in FIG. 7, in the steady rest device 1, each of the first connecting member 10 and the second connecting member 11 is arranged on the upper part of the mounting piece 110, and the upper part of the bolt member 50 extending upward from the mounting piece 110. Is fixed to each of the first connecting member 10 and the second connecting member 11. Further, each of the first connecting member 10 and the second connecting member 11 is connected to each other by the connecting members 20 and 21, and is fixed so as not to be relatively displaced in the Y direction. Further, a second regulating member 40 is attached to each of the first connecting member and the second connecting member 11. In the second regulating member 40 attached to the first connecting member 10, the vertical plate portion 43 at the tip is engaged with the upper edge portion of the back surface 102 of the ceiling suspension object 100, and the first connecting member 10 is suspended from the ceiling. It is restricted to move in the direction away from the back surface 102 of the object 100 (-Y direction). Further, in the second regulating member 40 attached to the second connecting member 11, the vertical plate portion 43 at the tip is engaged with the upper edge portion of the front surface 101 of the ceiling suspension object 100, and the second connecting member 11 is the ceiling. The movement of the suspended object 100 in the direction away from the front 101 (+ Y direction) is restricted. Therefore, the positions of the first connecting member 10 and the second connecting member 11 in the Y direction are fixed on the upper surface of the ceiling suspension 100 by the connecting members 20, 21 and the second regulating member 40, and a large-scale earthquake may occur. Even if it occurs, it does not slide on the upper surface of the ceiling suspension 100 in the Y direction.

In this way, the steady rest device 1 is attached in a state of being positioned with respect to the outside of the ceiling suspension object 100. Therefore, the steady rest device 1 becomes an integral structure with the ceiling suspension object 100, and the vibration caused by the bolt member 50 supporting the ceiling suspension object 100 being displaced relative to the ceiling suspension object 100 is effectively performed. It is possible to prevent it. Therefore, by using the steady rest device 1 of the present embodiment, it is possible to effectively prevent the lower portion of the bolt member 50 that supports the ceiling suspension object 100 from vibrating, and the ceiling suspension can be performed more than before. The vibration of the object 100 can be suppressed. By reinforcing the suspension bolt 9 with a conventional brace 213 (see FIG. 13), the steady rest effect of the suspension bolt 9 can be obtained.

By the way, it is preferable that the steady rest device 1 as described above is attached to the ceiling hanging object 100 in advance by floor work before the ceiling hanging object 100 is installed in the ceiling space. In this case, the suspension bolts 9 may be attached in advance to the insertion portions 14 provided at both the left and right ends of the first connecting member 10 and the second connecting member 11. However, if the lower part of the hanging bolt 9 attached to the ceiling structure such as a ceiling slab is attached to the steady rest device 1 in advance by floor work, when the ceiling hanging object 100 is lifted to a predetermined height position in the ceiling space, The upper end of the hanging bolt 9 must be fixed to the ceiling structure. Therefore, when the lower part of the hanging bolt 9 is attached to the steady rest device 1 in advance for floor work, it is preferable to attach the ceiling mounting bracket to the upper end of the hanging bolt 9 in advance.

FIG. 8 is a perspective view showing a configuration example of a steady rest device 1 attached to the ceiling suspension object 100 in floor work. The steady rest device 1 shown in FIG. 8 is different from the steady rest device 1 shown in FIG. 1 in that the ceiling mounting bracket 80 is attached to the upper end of the hanging bolt 9. As shown in FIG. 8, the steady rest device 1 is attached to the ceiling hanging object 100 in a state where the ceiling hanging object 100 is installed on the floor surface. By attaching the steady rest device 1 to the ceiling suspension object 100 in the floor work, the steady rest device 1 can be easily and efficiently attached to the ceiling suspension object 100.

When the steady rest device 1 is attached to the ceiling suspension object 100, the lower part of the suspension bolt 9 is subsequently attached to the left and right ends of the first connecting member 10 and the second connecting member 11 via the vibration isolating member 60 in the floor work. It is attached. That is, the lower portion of the hanging bolt 9 is attached to the steady rest device 1 in a state where the upper end portion of the hanging bolt 9 is not fixed to the ceiling structure such as the ceiling slab. Then, when the lower portion of the suspension bolt 9 is attached to the steady rest device 1 in the floor work, the ceiling installation metal fitting 80 is attached to the upper end portion of the suspension bolt 9. The ceiling mounting bracket 80 is also preliminarily attached to the upper end of the hanging bolt 9 by floor work.

FIG. 9 is an enlarged view showing an example of the mounting mode of the ceiling mounting bracket 80. As shown in FIG. 9, the ceiling mounting bracket 80 is a metal member mounted on the upper end of the hanging bolt 9, and has a substantially U-shaped shape. That is, the ceiling installation metal fitting 80 has a flat plate portion 81 and a pair of side plate portions 82 that are erected in parallel to each other on both sides of the flat plate portion 81. For example, the flat plate portion 81 is formed in a rectangular shape. Further, the flat plate portion 81 has a circular first hole 84 and an elongated hole-shaped second hole 85 adjacent to the first hole 84 and formed along the longitudinal direction of the flat plate portion 81. Is formed. The first hole 84 is, for example, a hole through which the upper end portion of the hanging bolt 9 is inserted, and is a hole having an inner diameter slightly larger than the outer diameter of the hanging bolt 9. The second hole 85 is a hole for inserting a bolt member such as an anchor bolt attached to a ceiling structure or a bolt attached to an insert, and is a long hole having an inner width slightly larger than the diameter of the bolt member. ..

Contrary to the above, an anchor bolt attached to the ceiling structure, a bolt attached to the insert, or the like is inserted into the first hole 84, and the upper end portion of the suspension bolt 9 is inserted into the second hole 75. You may try to insert it. Further, since the first hole 84 and the second hole 85 do not necessarily have to be formed in a separated state, one elongated hole-shaped mounting in which the first hole 84 and the second hole 85 are communicated with each other is installed. A hole may be formed, and a hanging bolt 9 may be inserted through the one mounting hole together with a bolt member to be attached to the ceiling structure.

The height of both ends of the pair of side plate portions 82 is higher than that of the central portion in the longitudinal direction of the flat plate portion 81, and the joint portions 83 in which both end portions abut against a ceiling structure such as a ceiling slab or a deck plate. Is formed as. Since the central portion of the side plate portion 82 in the longitudinal direction is lower than the joint portions 83 at both ends, the ceiling installation metal fitting 80 uses the low central portion as a window even when the joint portion 83 is in contact with the ceiling structure. There is an advantage that it is possible to visually check the state of the inside of the window. Further, when the deck plate has a corrugated shape having peaks and valleys and a groove for mounting an insert is formed in the center of the peak, a low-height portion is provided in the center of the side plate 82. There is also an advantage that the ceiling installation metal fitting 80 can be installed in a state where the joint portion 83 is in contact with the lower surface of the deck plate without interfering with the groove portion of the deck plate.

Such a ceiling mounting bracket 80 is attached to the upper end portion of the hanging bolt 9 by using the long nut 88 and the nut 89. That is, the long nut 88 is first attached to the upper end of the hanging bolt 9, and the tip of the hanging bolt 9 is projected from the upper end of the long nut 88, and the protruding tip is the first hole of the ceiling mounting bracket 80. Insert the nut 89 through the 84. As a result, the ceiling mounting bracket 80 is temporarily fixed to the upper end of the hanging bolt 9. Here, the height H of the joint portions 83 provided on the pair of side plate portions 82 may be at least the height dimension of the nut 89 or more. However, assuming that the ceiling mounting bracket 80 is attached to a bolt mounted on the insert, the height H of the joint portion 83 is higher than the height dimension of the insert that protrudes downward from the ceiling structure. It is preferable to design in advance.

The long nut 88 has a predetermined length in the axial direction, and has a female screw that is screwed with the male screw of the hanging bolt 9. In the ceiling mounting bracket 80, the lower surface of the flat plate portion 81 is supported on the upper surface of the long nut 88 with the long nut 88 attached to the hanging bolt 9. Since the first hole 84 through which the suspension bolt 9 is inserted in the ceiling installation bracket 80 is slightly larger than the outer diameter of the suspension bolt 9, the suspension bolt 9 is inserted through the first hole 84 in the ceiling installation bracket 80. In this state, the suspension bolt 9 can rotate around the axis. A nut 89 is attached to the tip of the hanging bolt 9 in order to prevent the ceiling mounting bracket 80 from falling out of the hanging bolt 9. It is preferable to use a nut 89 having a locking function or a retaining function for preventing the nut 89 from falling off from the tip of the hanging bolt 9.

As described above, the ceiling mounting bracket 80 is attached by sandwiching the flat plate portion 81 between the long nut 88 and the nut 89 with respect to the upper end portion of the hanging bolt 9. When the long nut 88 is not tightly fastened to the lower surface of the ceiling mounting bracket 80, the ceiling mounting bracket 80 can rotate about the axis of the hanging bolt 9 as described above. That is, the ceiling mounting bracket 80 rotates around the axis of the hanging bolt 9 when temporarily fixed. On the other hand, when the long nut 88 is tightly fastened to the lower surface of the ceiling mounting bracket 80, the ceiling mounting bracket 80 is fixed in a state of being sandwiched between the long nut 88 and the nut 89, so that the ceiling mounting bracket 80 is suspended. It is in a state where it does not rotate around the axis of the bolt 9. Then, in the floor work, the ceiling installation metal fitting 80 is temporarily fixed and attached to the upper end of the hanging bolt 9.

FIG. 10 is a diagram illustrating a mode in which the ceiling suspension object 100 to which the steady rest device 1 is attached is installed in the ceiling space. When the steady rest device 1 is attached to the ceiling suspension object 100 as described above, the ceiling suspension object 100 is lifted into the ceiling space by using an elevator or the like (not shown). At this time, as shown in FIG. 10, a bolt member 4 is installed in advance in the ceiling structure 3 such as a ceiling slab, and the ceiling installation metal fitting 80 attached to the upper end of the suspension bolt 9 with respect to the bolt member 4. Are concatenated. The bolt member 4 is a member such as an anchor bolt attached to a ceiling structure such as a ceiling slab or a bolt attached to an insert. For example, when four hanging bolts 9 are attached to the ceiling structure, four bolt members 4 are installed in advance in the ceiling structure. At this time, an error may occur in the installation position of each bolt member 4. Even in such a case, since the ceiling mounting bracket 80 can rotate around the axis of the hanging bolt 9, the second hole 85 can be rotated so as to match the position of the bolt member 4. it can. Then, the ceiling mounting bracket 80 can be attached to the ceiling structure 3 by inserting the bolt member 4 into the second hole 85 and tightening the nut 5 to the tip of the bolt member 4 protruding from the lower surface of the ceiling mounting bracket 80. .. For example, as shown in FIG. 10, even if the distance W1 between the two bolt members 4 arranged along the Y direction is smaller than the predetermined distance (the distance between the two hanging bolts 9), the ceiling is installed. By rotating the metal fitting 80, the ceiling installation metal fitting 80 can be installed on the two bolt members 4. Then, after fixing the ceiling mounting bracket 80 to the ceiling structure 3, the steady rest device 1 can be fixed to the ceiling structure 3 by tightening and fixing the long nut 88 located at the lower part of the ceiling mounting bracket 80. .. Therefore, the steady rest device 1 of the present embodiment can easily and efficiently perform the work when the ceiling suspension object 100 is installed in a state of being suspended in the ceiling space.

Further, even when the bolt member 4 protruding downward from the ceiling structure 3 is slightly inclined, the ceiling installation metal fitting 80 can insert the inclined bolt member 4 into the second hole 85. .. Therefore, the steady rest device 1 of the present embodiment has a ceiling structure of the steady rest device 1 that supports the ceiling hanging object 100 by using the bolt member 4 even when the bolt member 4 is slightly tilted. It is possible to fix it to 3.

Next, FIG. 11 is a side view showing a configuration example in which braces 91 serving as diagonal reinforcing members are cross-arranged between a plurality of suspension bolts 9. For example, when the length of the suspension bolt 9 is equal to or longer than a predetermined length, the steady rest device 1 has a brace 91 crossed between the plurality of suspension bolts 9 as shown in FIG. 11 to restrain the suspension bolt 9. Is preferable. That is, as shown in FIG. 11, brace connecting metal fittings 90 are attached to the upper part and the lower part of each hanging bolt 9, the brace 91 is diagonally arranged between the hanging bolts 9 adjacent to each other, and one end of the brace 91 is placed on one side. It is connected to the brace connecting metal fitting 90 attached to the upper part of the hanging bolt 9, and the other end of the brace 91 is connected to the brace connecting metal fitting 90 attached to the lower part of the other hanging bolt 9. In this way, the two braces 91 are attached in a state of being cross-arranged between the two hanging bolts 9. As shown in FIG. 11, the steady rest device 1 of the present embodiment can also perform the work of attaching the brace 91 between the plurality of hanging bolts 9 as the floor surface work. Therefore, if the steady rest device 1 of the present embodiment is used, it is not necessary to perform the work of attaching the brace 91 between the plurality of hanging bolts 9 as a work at a high place, and the brace 91 can be attached safely and efficiently. is there.

As described above, the steady rest device 1 of the present embodiment is a bolt member 50 attached to mounting pieces 110 provided at a plurality of locations near the lower portions of the left and right side surfaces 103 and 104 of the box-shaped ceiling suspension 100.

The upper part of the 50 is connected and fixed to the first connecting member 10, and the second fixing member 17 is configured to connect and fix the upper part of the bolt member 50 to the second connecting member 11. Then, the first fixing member 15 and the second fixing member 17 press each of the first connecting member 10 and the second connecting member 11 along the axial direction of the bolt member 50, whereby the first connecting member 10 and the second connecting member 10 and the second connecting member 17 are pressed. Each of the connecting members 11 is fixed in a state of being pressed against the upper surface of the ceiling suspension object 100.

Can be suppressed.

Further, the steady rest device 1 of the present embodiment has a hanging bolt 9 that supports a ceiling hanging object 100 suspended from the ceiling structure at both left and right ends of the first connecting member 10 and the second connecting member 11. It has a mounting portion 14a for mounting the above. A vibration-proof member 60 is attached to the mounting portion 14a, and a suspension bolt 9 is attached to each of the first connecting member 10 and the second connecting member 11 via the vibration-proofing member 60. Therefore, even if the ceiling suspension 100 generates vibration during the operation of the ceiling suspension 100, it is possible to suppress the vibration from being transmitted to the suspension bolt 9, and the upper floor is in a quiet state. Can be maintained at.
