Description

  The present invention relates to a horizontal member joining apparatus applied to join horizontal members such as beams and girders of a wooden building to structural members such as columns and trunks.

  A horizontal plate such as a beam or girder is joined to the side of a structural material such as a column or a trunk, and the back plate is placed relative to both sides of the back plate. A joint fitting having a U-shaped cross section composed of a side plate provided with a hole is fixed to the side plate of the structural member with the back plate overlapped with the side surface of the structural member, and a recessed portion of a lower surface opening is formed on the end surface of the horizontal member. A reinforcing plate is engaged with the engagement groove on the open end side of the recess and the slit groove on the back end side communicating with the engagement groove, and the engagement gap of the joint fitting is provided for each slit groove. And a locking rod that engages with the receiving edge of the joint fitting when engaged with the engagement gap above the open end side of the reinforcing plate. There is a structure in which the reinforcing plate is provided with an insertion hole of a locking rod that is installed through a part and is made to match the insertion hole through the horizontal member (for example, Patent Document 1).

JP 2003-227175 A

  In the conventional example, the pair of reinforcing plates are configured separately from each other. Therefore, when the reinforcing plates are assembled to the ends of the horizontal members using the locking rods, the reinforcing plates are supported. The mounting hole provided in the reinforcing plate and the fixing hole provided on the horizontal member side must be matched, and a fixing rod must be inserted through these holes, and the reinforcing plate is assembled to the horizontal member. Work becomes complicated.

  Further, in the joined state, the load applied to the horizontal member is generally concentrated and loaded on the fixing rod in terms of configuration, and there is a possibility that the vicinity of the fixing rod of the horizontal member may be torn.

  The present invention was devised for the purpose of providing a joining apparatus for a horizontal member that has the same joining strength as that of the conventional example and that reduces the complexity of assembly and the risk of laceration as much as possible.

  On the side of a structural material such as a column or trunk that joins horizontal members such as beams and girders, the back plate and relative to both sides of the back plate are provided. A joint metal having a U-shaped cross section composed of a side plate provided with each of the side plates is fixed with the back plate overlaid on the side surface of the structural material, and a recessed portion of a lower surface opening is provided on the end surface of the horizontal material. A pair of reinforcing plates engaged with an engaging groove on the open end side of the recessed portion and a slit groove on the far end side communicating with the engaging groove, and a fastening hole on the reinforcing plate side and the horizontal member side When the fastening rod is inserted into the fastening hole and attached to the end portion of the horizontal member, the joining when the engaging plate is engaged with the engaging gap between the reinforcing plates above the open end side of the reinforcing plate. A latching rod for hanging on the receiving edge of the hardware is constructed through the end of the horizontal member, and connected to the connecting rod inserted through the horizontal member so as to coincide with the connection hole. A basic means is that a hole is provided in the reinforcing plate, and the reinforcing plate is integrally connected to each other at the lower end of the rear end portion by an intermediate plate whose upper surface is in contact with the lower end of the horizontal member, thereby forming a connection hardware. .

According to the present invention, as in the conventional example, it is possible to provide a joining device that can reliably join the horizontal member to the structural member. Of course, the pair of reinforcing plates are connected via the mediating plate to form the connection hardware. Since it is configured as a material that can be handled as a single unit, there is no need to align the reinforcing plates, so that the assembly work for the horizontal member can be easily performed, and a relatively joining operation can be performed. It is possible to provide a joining apparatus that can perform smoothly. Moreover, since the intermediate plate receives a load from the side of the horizontal member, it is possible to reduce the possibility of tearing of the horizontal member as compared with the case where the intermediate plate is received only by a fastening rod or the like.

  The connection hardware 2 is a steel frame having a U-shaped longitudinal section composed of a pair of rectangular reinforcing plates 5 and 5 and an intermediate plate 6 in which the reinforcing plates 5 and 5 are connected and integrated at the lower end of the rear end. It is composed of a body, and at the front end portion (one side portion of the structural material 3 side) of the reinforcing plates 5 and 5, a through hole 8 for inserting the retaining rod 7 and a connecting rod 9 are inserted directly below the through hole 8. A pair of connection holes 10 and 10 are provided, and a pair of fastening holes 12 and 12 for inserting the fastening rod 11 are arranged in the vertical direction at a position immediately above the intermediate plate 6 at the rear end. Is.

  At the front end of the side surface of the end portion 1 ′ of the horizontal member 1, a through hole is formed so as to coincide with the through hole 8 provided at the front end portion of the reinforcing plate 5 of the connection hardware 2 and the pair of connection holes 10, 10. 8A and a pair of connection holes 10A, 10A are provided, and fastening holes 12A, 12A are provided at positions that coincide with the fastening holes 12, 12 provided in the reinforcing plate 5 on the rear side of the connection holes 10A. A recessed portion 13 having a lower surface opening that is orthogonal to the hole 8A, the connection hole 10A, and the fastening hole 12A is provided in the end surface 1'a of the horizontal member 1.

The recessed portion 13 is composed of an engagement groove 13a on the end surface 1'a side, that is, an open end side, and slit grooves 13b and 13b at both corners on the back end side communicating with the engagement groove 13a. In this recessed portion 13 provided on the end surface 1'a, the reinforcing plate 5 is attached to the tongue-like horizontal member piece 1a in which the upper surface of the intermediate plate 6 is partitioned by slit grooves 13b and 13b from the lower end side of the opening. Insertion until contact is made, that is, until the reinforcing plate 5 comes into contact with the horizontal member piece 1a by placing the reinforcing plate 5 immediately below the slit groove 13b that is disengaged from the engaging groove 13a. When inserted and assembled, the fastening rod 11 is inserted into the fastening hole 12 on the side of the horizontal member 1 and the fastening hole 12A on the side of the connection hardware 2 (reinforcing plate 5), which are provided in advance so as to coincide with each other. Similarly, the through hole 8A on the horizontal member 1 side and the connection hardware 2 (reinforcement) provided so as to coincide with each other. The latch 5 is inserted into the through-hole 8 on the plate 5) side from the through-hole 8A side, and the connecting hardware 2 is attached to the end of the horizontal member 1 to obtain the horizontal member 1 in which the connecting hardware 2 is assembled. It is done.

  The metal fitting 4 is provided on the back plate 14 and both sides of the back plate 14, and a receiving edge 15 having a semicircular bottom edge on the upper edge is provided at an appropriate position directly below the receiving edge 15.
