[0013]

Next, the present invention will be described in detail with reference to the drawings. FIG. 1 shows an example of a fitting and a fitting device for connecting three or more structural members according to the present invention.
Connects the upper first vertical member and the lower second vertical member such that their connection surfaces face each other, and makes contact with the side of the connection of the first vertical member such as a beam. It is a figure for explaining a connection metal fitting device used when connecting a bridge.

As shown in FIG. 1, a connecting device 1 for connecting three or more architectural structural members according to the present invention comprises two connecting members 2 and a cross member receiving plate 3. Each of the two connection fittings 2 is a predetermined one along the axis over the entire width of the connection, which is the upper one of the first and second two vertical members connected to each other. One of the grooves 5 of the first building structural member (first vertical member) 7 provided with two grooves 5 having a depth of at least one and provided with at least one through hole 6 crossing the groove 5 A first fitting portion 8 to be fitted in the groove, and a groove 9 having a predetermined depth along the axis extending over the entire width of the connection, which is located below, and provided in the connection 9. A second building is provided with at least one through-hole 11 crossing the opening 10 and connected to the first vertical member 7 with the surfaces of the connections 4, 9 facing each other. A second fitting portion 13 fitted into one of the grooves 10 of the structural member for use (second vertical member) 12, and a fitting portion 14 having a predetermined depth along the axis over the entire width of the fitting. A groove 15 for the streaks is provided, and at least one through hole 16 crossing the groove 15 is provided.
The groove 15 of at least one third building structural member (horizontal member) 17 connected to the side of the connection 4 of the vertical member 7
And a third fitting portion 18 fitted into one of the
The whole is formed in a substantially T-shaped flat plate shape.

When the first vertical member 7 and the second vertical member 12 and the horizontal member 17 are connected to the fitting portions 8, 13, 18, the through holes 6, 11, 16 are formed. At least one of the insertion holes 20, 21, 22 for inserting the fixing rod 19 is provided at at least one position corresponding to each of the through holes 6, 11, 16. Have been.

The length of each of the fitting portions 8, 13, 18 (for example, the length of the third fitting portion is represented by L in the figure) is
The depths of the grooves 5, 10 and 15 into which the respective insertion portions are inserted are set to be equal to or slightly shorter than the depths of the grooves (for example, the depth of the groove 15 is indicated by D in the drawing). Normally, the depths of the grooves 5, 10, 15 of the structural members 7, 12, 17 are processed to be slightly deeper than the lengths of the respective fitting portions, based on the lengths of the respective fitting portions. It is preferable that the depth and the length of each corresponding fitting portion are the same. With such a configuration, in the description of the operation that will be described in detail later, the weight of the combined beam and upper column is reduced by the through hole of the lower column through the second fitting portion and the fixing rod, Since it is applied not only to the connection with the pillar but also to the protruding end 10a of the groove 10 of the lower pillar via the second fitting portion, the weight is more evenly distributed, and the risk of damage to the structural member is further avoided. it can.

In addition, the weight of the upper column is supported not only by the insertion hole 20 but also by the protruding end 5a of the groove 5 via the inner edge of the through hole 6 of the first fitting portion 8 and the fixing rod-shaped member 19. Therefore, it is easier to avoid the risk of damage to the through-hole 6 of the structural member, the fixing rod-shaped member 19 and the connection fitting 2.

The horizontal member receiving plate 3 is formed by the first vertical member 7 and the second vertical member 7.

A horizontal member receiving portion 24 is extended from the substrate 23 so that the second fitting portion 13 of the connection fitting 1 can be inserted into a portion of the substrate 23.
The number of the slits 25 is equal to or more than the number of the connection metal fittings long in the direction along any one side of the above, preferably the same number.

FIG. 1 shows an example of a case where two connecting metal fittings 2 are used as a set so that their respective fitting portions are parallel to each other. The number of the slits 25 is two according to the number of the second fitting portions 13 of the metal fitting 2.
It is an aspect provided with an article. The alternate long and short dash line in the drawing indicates a state in which the cross member receiving plate 3 is fitted into the second fitting portion 13 and the horizontal member receiving portion 24 is in close contact with the lower edge of the third fitting portion 18.

The roots of the first fitting portion 8 and the third fitting portion 18 between the second fitting portion 13 and the first fitting 7 of the connection fitting 2 are connected to the upper first vertical member 7. The fitting portion 8 of

The length of the portion 24 extending outward from the substrate 23 is equal to or slightly longer than d;
A notch 26 is provided which is cut out to a depth substantially equal to the thickness t of the cross member receiving portion 24. Corresponding to this, a cutout portion 17a is provided in a portion of the horizontal member 17 at the joint portion with the vertical member 7. This is a structure for preventing the horizontal member receiving plate 3 from protruding below the horizontal member, and by doing so, as shown in FIG.
In the case where a structure in which the wall frame W is provided between the second frame 2 and the horizontal member 17 is employed, it is possible to prevent a gap from being formed between the wall frame W and the vertical members 12, 12, and the horizontal member 17.

FIGS. 2B and 2C show an example in which the notched portion 17a is not provided. Vertical member 1 as shown in (b)
If a gap is not formed between the horizontal member 17 and the wall frame W, a gap P is formed between the horizontal member 17 and the wall frame W, and as shown in FIG. If a gap is not formed between the vertical members 12 and the wall frame W, a gap Q is formed between the vertical members 12 and the wall frame W.

However, in the present invention, the cross member receiving plate 3 does not necessarily have to be used, and in that case, it is not necessary to provide the cutout portion 17a, so that the processing time is reduced. However, in this case, the effect when the cross member receiving plate 3 is used, which will be described later, cannot be obtained.

In the present invention, each connecting fitting 2 may be a flat plate, and its overall shape is not limited to the above-described substantially T-shape. For example, the third fitting as shown in FIG. May have a substantially inverted L-shape such that the number of fitting portions is one. In FIG. 3, S is a cut. Third
On the side where the fitting portion does not exist, that is, on the side where the horizontal agent is not connected, the horizontal agent receiving portion 24 of the horizontal agent receiving plate 3 also does not exist (it is necessary or rather obstructive), so the end of the slit on this side is Naturally, it is located inside the end of the horizontal agent receiving plate 3. S is provided to match the length and position of this slit.

The connection fitting device 1 in which the connection fitting 2 and the cross member receiving plate 3 are combined, connects the upper and lower vertical members, and attaches one or more horizontal members to the connection side surface of the upper vertical member. In particular, when connecting a horizontal member such as a beam, specifically, as shown in FIG. 4, it is preferably used when an upper column 28 is added to a lower column 27 and a beam 29 is connected to the upper column 28. Can be used.

That is, as shown in FIG. 4A, two third fitting portions 18 are provided as shown in FIG.

The above-mentioned beam receiving fitting will be described with reference to FIG. The above-mentioned beam receiving bracket is composed of A, two side plate pieces whose upper edges are obliquely inclined, and a tenon portion protruding rearward. The side edge of the notch support portion on the front end side of the side plate piece is inclined so that the notch support portion becomes wider toward the upper portion. For example, as shown in FIG. A tenon part b having a vertically long fixture insertion hole a in the center of the rear surface thereof, and two side plate pieces c and c having a part of the rear end connected by the tenon part b; The side plate piece c is formed such that an upper edge thereof is inclined obliquely from a rear end side to a front end side of the side plate piece c, is notched downward from the upper end edge, and becomes wider toward an opening. A notch support portion d in which the side edge on the front end side of the piece c is inclined is formed, and two fixture engagement holes e are further provided. It is intended.

Further, the above-mentioned beam receiving fitting B has a box-shaped tenon portion provided with a fixing through-hole on the back side, with a side plate piece drilled so that the fixing engaging hole is vertically symmetrical. 6 are connected symmetrically in the vertical direction.
As shown in (b), the fixing holes f, f,... Are provided so as to be vertically symmetric with respect to the center line M of the side plate piece g, and are further inserted through the rear surface. The side plate pieces j, j as described above are vertically symmetrically connected about the center line M by a box-shaped tenon portion i, i provided with a hole h.

The use of the connecting fitting device of the present invention, compared to the case where three or more beams are connected to a column by using the above-described beam receiving fittings alone, a) the structure of the fitting device used; Simple materials can be used, a) Easy to process into structural materials, c) Easy to attach to structural materials, d) Weight of beam is distributed to both beam receiving plate and connecting bracket Therefore, there is an advantage that a weight burden on the connection fitting is small.

When the connecting bracket or the connecting bracket device of the present invention is used in combination with the above-mentioned beam receiving bracket, a maximum of four horizontal members can be connected to the vertical member. Since the receiving bracket and the connecting bracket of the present invention can be simultaneously and simultaneously fixed to the vertical member (for example, the upper pillar) with only one fixing rod-shaped member such as one drift pin, the above-mentioned 4
The largest number of horizontal members, called books, can be connected to the vertical members very easily. Of course, since the vertical members (for example, the upper pillar and the lower pillar) can be vertically connected by the connecting metal fittings of the present invention, a total of six building structural members can be connected by extremely simple means. There is.

As shown in FIG. 1, the connection fitting 2 is provided at the uppermost one of the insertion holes 22 for inserting the fixing rod-shaped member 19 in the third insertion portion 18 which is inserted into the beam 29. Instead of the hole, a concave notch 32 opened upward is provided. The concave notch 32 is formed in a so-called dovetail shape in which the edges thereof are inclined toward both left and right sides of the connecting metal fitting 2 so as to gradually increase in width from the middle in the vertical direction of the connecting metal fitting 2 to the upper side. And the through hole 1 of the beam 29
When the fixing rod-shaped member 19 such as a drift pin or a bolt is inserted and fixed in advance in the uppermost through hole 16 a of the 6, the third fitting portion 18 is inserted into the groove 15 of the beam 29. The beam can be temporarily fixed to the third fitting portion 18 only by lowering the beam 29 from above the third fitting portion 18 and hooking the fixing bar-shaped member 19 on the concave notch portion 32. There is an advantage that it is not necessary to perform alignment between the other through-hole 16 and the through-hole 22 provided at a position corresponding to the other through-hole 16, and the connecting operation can be performed quickly and reliably.

Next, the metal fitting for connecting three or more structural members of the present invention will be described with reference to FIG. The connection fitting 2 of the three or more structural members for construction of the present invention corresponds to the connection fitting in the connection fitting device described above. The connection fitting 2 can be used alone without being combined with the cross member receiving plate 3.

Even if it is used, the same operation and effect as the operation and effect obtained from the combination of the connection fitting 2 and the cross member receiving plate 3 when used for connection between the column and the beam, which will be described later, can be obtained.

Further, when used in the manner described above, the side edges 8a, 13a of the first and second fitting portions 8, 13 facing the base concrete 36 of the connection fitting 2 are formed on the base 33. , 34 on the same plane. With this configuration, the pillar 35
Is also distributed not only directly to the base but also to the foundation concrete 36 via the connecting metal fitting 2, so that even if the connecting metal fitting 2 is used alone, the upper pillar is connected to the lower pillar, which will be described later. In addition, the same operational effects as those obtained from the combination of the connection fitting 2 and the cross member receiving plate 3 when used to connect the beam to the upper pillar are exhibited.

In the case of using as described above, specifically, as shown in FIG. 8 (a), the connecting fitting 2 is provided with a third fitting portion 18 on the first or second fitting portion side. The left and right bases 33 and 34 are interconnected by forming the whole into a substantially L-shaped form as shown in FIG. The pillar 35 can be connected to the projecting third fitting portion 18 by fixing one pillar 35 to the projecting third fitting portion 18, and as shown in FIG. The right and left bases 33 and 34 are connected to each other by being provided at an intermediate position between the first fitting part and the second fitting part so as to form a substantially T-shaped configuration. One pillar 3 is inserted into the third fitting portion 18 protruding from the upper surfaces of the bases 33 and 34. It may be configured to be coupled by fixing. The number of columns 35 fixed to the third fitting portion may be two or more.

Further, in the case of using as described above, instead of the uppermost insertion hole among the insertion holes for inserting the fixing rod-like members 19 in the first and second fitting portions 8 and 13, the above-mentioned insertion hole is used. It is preferable that a concave notch opened upward like the above is provided. The concave notch portion is configured such that the edges thereof are inclined toward the left and right ends of the connecting metal fitting 2 so as to gradually increase in width from the middle in the vertical direction of the connecting metal fitting 2 to the upper side.

In addition to connecting the left and right bases to each other,
When the bases arranged at right angles to the left and right bases are further connected to the connection portions of the left and right bases, as shown in FIG. Either or both of the necessary surfaces 40 and 41 other than the certain connection 39 side surface, or any of the necessary surfaces 44 and 45 other than the connection 43 side surface with the groove 42 of the second base 34 In both or both, the aforementioned Japanese Utility Model Laid-Open No. 6-37420.
No. 5, the beam receiving fitting A with a mortise for construction disclosed in Japanese Patent Application Publication No. 5-53315, and the beam receiving fitting B such as a beam receiving mortise with a mortise for construction. Even if these beam receiving brackets are used for connection of the horizontal members such as the base to the vertical members or for connecting and fixing the horizontal members to each other, the horizontal members such as the beams are connected to the vertical members such as the columns described above. In this case, the same effect as in the case where it is used is exhibited.

The metal fitting for connecting three or more architectural structural members and the metal fitting device for connecting three or more architectural structural members according to the present invention, when they are used, connect two or more of the metal joints to one. As a set, they can be arranged and used so that the respective fitting portions are parallel to each other. In this case, the grooves of each connection are provided by the number of connection fittings used. When two or more connection brackets are used in combination, the durability against torsion and bending is more than the combined number of times compared to the case where one connection bracket is used. When the bending strength is to be obtained, the thickness per connection fitting can be reduced, or a material having low torsional strength and bending strength can be used.
When the same material and the same thickness are used as in the case of using only one connection fitting, good durability against torsion and bending is exhibited.

As described above, according to the present invention, the metal fitting for connecting three or more structural members for construction is formed over the width of the connection of the structural member to be connected such as a pillar, a beam or a base. By simply providing a groove having a predetermined depth, three or more structural structural members can be connected, and the connecting metal fittings are the first, second, and third members.
It has a flat plate shape of a predetermined shape having each of the fitting portions described above, and is provided with a through hole for a fixing rod-shaped member at a predetermined position, so that the structure can be made easily and easily. Therefore, mass production is easy. This also has the advantage that the manufacturing cost can be reduced and as a result, inexpensive products can be supplied in large quantities. In addition, processing of structural members for construction may be performed only with slit-shaped grooves and through-holes.To process slit-shaped grooves, grooving with an electric saw such as a circular saw, and processing of through-holes In any case, such as drilling using an electric drill or the like, it is possible to easily perform processing using a simple processing means, so that there is an effect that the labor of processing can be reduced as compared with the related art.

Further, the above-mentioned connecting metal fitting is formed by adding another vertical member to the upper part of the vertical member, for example, by adding another column above the column and connecting a beam to the upper column. When it is used for connecting a horizontal member to a vertical member, there is an advantage that attachment to a structural member can be simplified as compared with a conventional metal fitting for connecting three or more structural members.

In the above-mentioned use mode, when the connecting member is used in combination with the cross member receiving plate and the cross member receiving plate is arranged between the upper column and the lower column, Is also distributed to the cross member receiving plate, so that the weight of the fitting rod-shaped member insertion hole of the fitting portion or the fixing rod-shaped member, or the weight of the connection portion or each connection portion or the connection side surface of the connection portion is reduced. As a result, the durability of the connection portion can be improved by preventing the above members and parts from being damaged, and as a result, it is possible to contribute to an improvement in the safety of the building.

Further, when a plurality of the above-mentioned connecting fittings are used, the strength is markedly higher than when one connecting fitting corresponding to the total thickness of each connecting fitting is used. Is obtained. Therefore, the thickness of one connection fitting required to satisfy the predetermined strength can be reduced, so that the weight of the connection fitting can be reduced, the handling is simplified, and the material is reduced, resulting in low cost. This results in the advantage that

In the case where the connecting fitting is used for connecting the horizontal members and connecting the vertical member to the upper surface of the horizontal member, the base is connected to each other and the pillar is connected to the upper surface of the base. In this case, even if there is no cross member receiving plate, the same operation and effect can be obtained as in the case where there is a cross member receiving plate.
