DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for joining a horizontal member such as a beam of a wooden building to a framed body such as a pillar.

[0002]

2. Description of the Related Art There is a structure in which a groove-like joining metal fitting having an upper end opening is projected from a material to be joined such as a pillar or a beam, and an end of a horizontal member such as a beam is engaged with the joining metal and fixed. is there.

[0003]

In the conventional example, it is not necessary to apply so-called tenon processing or tenon processing to wood.
Although there is an advantage that it is possible to prevent a decrease in the strength of the wood due to the provision of a tenon, there is a possibility that the so-called floating may occur because the structural member is weak against external force from below.

[0004] The present invention focuses on such disadvantages of the conventional example,
This invention was devised to provide a joining device for horizontal members having excellent joining strength.

[0005]

SUMMARY OF THE INVENTION A base metal and an assembling part which overlaps the base metal with an engagement interval at an engagement interval are connected to each other via a bent lower end portion. The base piece is engaged with the concave portion provided on the surface of the frame assembly and fixed to the frame assembly, and the joining plate overlapped on the end surface of the horizontal member is engaged with the engagement gap of the joining fitting. And bolted to the frame assembly, and under the bent engaging portion provided at the upper end of the mounting portion engaged in the transverse member, the width direction of the transverse member is reduced. The engagement rod is inserted into the engagement rod.
