[One embodiment of the joint fitting and receiving bracket for construction]
FIG. 1: has shown the schematic exploded perspective view of the joining metal fitting for construction concerning one Embodiment of this invention.
In FIG. 1, a construction fitting 1 includes a fitting 2 fixed to a pillar 5 as a first wooden member and a connecting fitting 3 attached to a beam 6 as a second wooden member. The beam 6 is joined to the column 5 by connecting the metal fitting 2 and the connection metal fitting 3.
In the present embodiment, the first wooden member is the pillar 5 and the second wooden member is the beam 6, but the present invention is not limited to these.

(Receiver bracket)
2A and 2B are schematic diagrams for explaining a metal fitting for a building joint according to an embodiment of the present invention, in which FIG. 2A is a front view, FIG. 2B is a right side view, and FIG. A top view is shown.
In FIG. 2, the receiving metal fitting 2 protrudes from the pair of fixing plates 21 and the inner edge portion 212 of the pair of fixing plates 21 in the front direction (when viewed from above, substantially perpendicular to the fixing plate 21). A pair of opposed connecting side plates 22 and a connecting front plate 23 for connecting the pair of connecting side plates 22 to each other.
The metal fitting 2 is usually formed integrally by pressing a single steel plate. In this way, the manufacturing cost can be reduced. Moreover, it is not limited to press work, For example, you may use welding together.

The fixing plate 21 is a flat plate elongated in the vertical direction, and fixing member holes 211 are formed at two locations in the vertical direction. The fixing member holes 211 of the fixing plates 21 are separated from each other by a pitch p.
In this embodiment, the coach screw 41 is used as the fixing member. The coach screw 41 is inserted into the fixing member hole 211 and is fastened to the pilot hole 51 of the column 5, thereby fixing the metal fitting 2 to the side surface of the column 5. As the fixing member, for example, a bolt and a nut (not shown) can be used instead of the coach screw 41.

Here, when the coach screw 41 is fastened to the column 5, only the head protrudes from the side surface of the column 5, that is, the protruding amount of the coach screw 41 is the height of the head. On the other hand, when bolts and nuts are used, one protruding amount when tightening is the height of the nut, and the other protruding amount is the height of the nut + the length of the bolt protruding from the nut. .
Usually, the height of the head of the coach screw 41 is shorter than the height of the nut + the length of the bolt protruding from the nut, so that by using the coach screw 41, the jaw hooking portion 221 and the connecting member hole 222 are formed in the column 5. Can be formed on the side. That is, since the width dimension of the connection side plate 22 can be shortened, the protruding amount (the distance from the side surface of the pillar 5 to the surface of the connection front plate 23) can be shortened. Thereby, when the pillar 5 to which the metal fitting 2 is fixed is loaded on a truck or the like and transported, the loading efficiency of the pillar 5 can be improved.

  Further, the height direction position of the fixing member hole 211 of the left fixing plate 21 is lower than the height direction position of the fixing member hole 211 of the right fixing plate 21 by Δp (Δp> the maximum of the coach screw 41. (Diameter). If it does in this way, since the coach screws 41 do not interfere as will be described later, the receiving metal fitting 2 can be fixed at the same height position on the four side surfaces of the column 5.

The connection side plate 22 is a flat plate elongated in the up-down direction, a jaw hooking portion 221 is formed in the upper portion, and a connection member hole 222 is formed in the lower portion.

Thereby, the drift pin 43 as a locking member can be easily and safely engaged in the jaw hooking part 221 from the upper side and the beam 6 side.
In addition, a drift pin 44 as a connecting member is inserted into the connecting member hole 222, whereby the receiving metal fitting 2 and the connecting metal fitting 3 are connected.

The connecting front plate 23 is a flat plate elongated in the vertical direction for connecting the edge portions 224 of the connecting side plate 22 on the beam 6 side, and has a vertical groove 231 formed therein.
The vertical groove 231 is formed downward from the upper end portion of the connection front plate 23, and the width of the vertical groove 231 is wider than the thickness of the mounting plate 31 so that the mounting plate 31 of the connection fitting 3 is inserted. It is as.
In addition, guide surfaces 232 are formed on both sides of the upper portion of the vertical groove 231 so that the opening width of the vertical groove 231 widens upward. With this guide surface 232, when the mounting plate 31 is fitted into the vertical groove 231, the allowable error of the position of the mounting plate 31 that is lowered (allowable error in the Y direction in FIG. 1) can be increased several times. Thereby, the connection metal fitting 3 can be easily and safely inserted into the vertical groove 231, and a great effect is exhibited in high-altitude work.

Further, the vertical groove 231 is formed from the upper end portion of the connecting front plate 23 to a predetermined position below. This predetermined position is a position where the vertical groove 231 locks the notch 35 of the connection fitting 3 when the connection fitting 3 moves downward and the drift pin 43 is locked to the jaw hooking portion 221. That is, the jaw hooking part 221 and the vertical groove 231 are in contact with the drift pin 43 and the notch part 35, respectively, and support the beam 6.
The predetermined position is not limited to the illustrated position, and may be, for example, higher.

In this embodiment, the lower part of the connection front plate 23 connects a pair of connection side plates 22, forms a cross section like a grooved steel, and the portions of the connection front plate 23 on both sides of the longitudinal groove 231 are: It is formed integrally with the connecting side plate 22 and forms a cross section like L-shaped steel. Thereby, the mechanical strength of the receiving metal fitting 2 can be improved significantly.

The ventilation path 242 formed by 61 is blocked. Thereby, fire spread can be effectively prevented.
In the present embodiment, the fire spread prevention plate 24 is attached to the metal fitting 2 by welding. However, the present invention is not limited to this. For example, a structure in which the steel plate is integrally formed with the metal fitting 2 may be adopted.
Further, the fire spread prevention member is not limited to the fire spread prevention plate 24. For example, a molded body made of a heat resistant material may be press-fitted into the air passage 241 and the air passage 242.

(Connecting bracket)
FIG. 3 is a schematic diagram for explaining a connecting bracket of a building joint bracket according to an embodiment of the present invention, wherein (a) is a front view, (b) is a top view, and (c) is a notch. The enlarged view of the part is shown.
The connection fitting 3 is a substantially rectangular flat plate (mounting plate 31), and a mounting member hole 32 into which a drift pin 42 as a mounting member is inserted is formed in an upper part and a lower part on the beam 6 side. Further, a locking member hole 33 into which a drift pin 43 as a locking member is inserted is formed in the upper part on the column 5 side, and a drift pin 44 as a connecting member is formed in the lower part on the column 5 side. A connecting member hole 34 to be inserted is formed. Furthermore, a trapezoidal notch 35 is formed in the lower part on the column 5 side.

The notch 35 has an upper surface 351 (a surface corresponding to the upper side of the trapezoid) and an inclined surface 352 (a surface corresponding to the oblique side of the trapezoid). By this inclined surface 352, when the notch 35 is locked to the bottom of the vertical groove 231, the tolerance of the position of the lowered mounting plate 31 (allowable error in the X direction in FIG. 1) can be increased several times. The notch 35 is smoothly locked to the bottom of the vertical groove 231.
Further, when the mounting plate 31 is fitted into the longitudinal groove 231, the inclined surface 352 contacts the connecting front plate 23, guides the mounting plate 31 in the X direction, and the guide surface 232 contacts the mounting plate 31. A synergistic effect of guiding 31 in the Y direction is produced. Thereby, the mounting plate 31 can be more easily fitted into the longitudinal groove 231 and workability and safety are greatly improved.

  Further, the upper end surface of the beam 6 is positioned by the drift pin 43 being locked to the jaw hooking portion 221, and the lower end surface of the beam 6 is locked to the bottom of the vertical groove 231. Is positioned. That is, since the length of the upper surface 351 in the X direction is substantially the same as the thickness of the connecting front plate 23, the lower end surface of the beam 6 is positioned by the notch 35 being locked to the bottom of the vertical groove 231. Is done. At this time, the pillar 5 and the beam 6 are attracted to each other by the slope 352. Thereby, the misalignment of the connecting member hole 222 of the receiving metal fitting 2 and the connecting member hole 34 of the connecting metal fitting 3 is reduced, and the drift pin 44 can be driven easily. Also by this, workability and safety can be improved.
