Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a connection structure between horizontal members in a wooden building.

[0002]

[Prior art]

 Conventionally, when connecting a horizontal member to a horizontal member in a wooden building, a tenon is generally formed at one side of the connecting portion, and the other tenon is fitted into the tenon to connect the horizontal member. .

However, when mortises and projections are formed in order to connect horizontal members to each other, problems such as large cross-sectional defects at the locations where the mortises and projections are formed, the inner surface of the tenon and projections of the tenon. There was a problem that the outer surface of the part was easily chipped and required high processing accuracy.

[0004]

[Problems to be solved by the invention]

 The present invention solves such a problem. In order to connect the horizontal members, it is possible to easily connect them without forming a mortice or a convex portion, and improve the strength of the connecting portion. The purpose is to do so.

[0005]

[Means for Solving the Problems]

 In order to solve this problem, according to the present invention, a receiving member is attached to a side surface of one of the lateral members connected to each other to receive an end of the other lateral member by being inserted from above, and the receiving member is connected to one lateral member. A plate portion contacting the side surface of the frame, a bottom plate portion connected to a lower end of the plate portion, and a pair of side plate portions connected to the plate portion and the bottom plate portion; and further, upper ends of a pair of side plate portions of the receiving metal member. Is formed with a substantially V-shaped guide groove, and the connection rod is inserted by inserting both ends of a connection rod inserted into a horizontal through hole formed at the end of the horizontal member from the upper end of the guide groove. In a state where the guide member is lowered to the lower end of the guide groove, the end surface of the other horizontal member abuts on the outer surface of the plate portion, and the lower end of the end portion of the other horizontal member rests on the bottom plate portion. The main point is that the horizontal members are connected by screws, etc. Than it is. According to the present invention, a horizontal through-hole is formed in one of the transverse members at a mounting position of the receiving hardware to one of the transverse members, and a pipe having an internal thread formed on the inner surface is inserted into the through-hole. Then, a bolt is screwed into the female screw portion from the bolt insertion hole with the female screw portion being aligned with the female screw portion at one end of the pipe, and a bolt is inserted into the female screw portion at the other end of the pipe. The gist of the invention is that the receiving hardware is fixed to one of the horizontal members by being screwed.

[0006] According to this configuration, by using a receiving metal without forming a tenon or a projection to connect the horizontal members, the horizontal members can be easily connected to each other. The strength of the connecting portion can also be improved. In particular, a substantially V-shaped guide groove is formed at the upper end of the pair of side plates of the receiving metal member, and the connecting rod is inserted into a horizontal through hole formed at the end of the other horizontal member. When the connecting rod is guided down to the lower end of the guide groove by fitting both ends from the upper end of the guide groove, the end surface of the other horizontal member comes into contact with the outer surface of the plate portion and the end of the other horizontal member. Since the lower end of the portion is configured to rest on the bottom plate portion of the receiving hardware, the other horizontal member can be easily positioned with respect to the receiving hardware. Further, a horizontal through-hole is formed in one of the transverse members, a pipe having a female screw portion formed on the inner surface thereof is inserted into the through-hole, and a bolt is screwed into the female screw portion from both ends of the pipe to thereby form the other. With the configuration in which the receiving member for receiving the horizontal member is fixed to one of the horizontal members, the receiving member for receiving the other horizontal member is firmly fixed to the one horizontal member.
