DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an architectural joint for use in a wooden building which is formed by bending and forming a metal plate of a required shape in which bolt holes, drift pin mounting holes or mounting grooves are formed in advance. It is.

[0002]

2. Description of the Related Art A conventional architectural joint is formed by bending and forming a metal plate of a required shape having a mounting hole or a mounting groove (slit) through which a drift pin is inserted in both wings. The back formed by bending is bolted to one of the building materials (horizontal member or column) so as to be continuous. Then, the two wings are fitted into the joining slits formed on the other of the building materials (posts, horizontal members, etc.), and penetrated through the drift pins, thereby connecting one and the other of the wood-based building materials. Are joined.

[0003]

As described above, in this type of connector, a vertical load is applied from the other (horizontal member) side of the building material by the two wings.
Each of the two wings only extends in a plate shape from the base end continuous to the back to the tip, and thus has a problem in strength. In addition, there is no way to control the distance between the front ends of the two wings, and there is a case where it is not possible to fit into the joining slit at the beam end on the other side at the joining site. In this case, on-site work such as increasing the slit interval is required. Also, if the thickness of the metal plate is not sufficient, after joining, when tension is applied between one and the other of the building materials, the bolted back portion is connected via the two wing portions connected to the back portion. It may be pulled, bent and deformed. As a result, there is a basic problem that the joining interval is shifted. Further, when the above-mentioned back portion is bolted, the insertion of the bolt may become insufficient or, conversely, the bolt may be turned too much and the bolt may become ridiculous.

The present invention has been made based on the above circumstances, and increases the strength of the back portion to which a large load is applied, avoids deformation due to a tensile load, and increases the strength for receiving a vertical load by both wing portions. It is an object of the present invention to provide an improved architectural joint in which the distance between the two wings is kept constant, and when the joint is fitted to the slit for joining, an improper fitting does not occur. In addition, it prevents cracks in the mouth.
