  When attaching a wooden member on a base material which is a wooden member, the most common attachment means is nailing or screwing. However, when nailing or screwing, the head is exposed on the surface of the member to be attached, and the appearance of the attachment structure is impaired. Therefore, another cover material may be attached so that the head portion is not exposed on the surface, or a hole may be provided and driven, and processing may be performed to fill the hole after nailing or screwing.

  FIG. 7 shows a specific example in which the member A is attached to the member B by screwing, and the screw (A) reaches the member B through the member A. However, the head of the screw (A) is exposed on the surface of the member A, and post-processing is required to cover the head so that the head cannot be seen. If the members A and B are long materials, the heads of a plurality of screws (b), (b). Of course, it is necessary to drive a plurality of screws (A), (A).

  Further, when the member A is screwed in a state where the member A is placed on the surface of the member B, the member A may be displaced during the screwing process. For example, when the screw is tightened while being tilted with respect to the surface of the member B, the member A is laterally displaced. This lateral displacement occurs more prominently when the member A is hammered, and it is difficult to fix the member A at a predetermined position of the member B.

  FIG. 8 shows another joint structure in which the member A is attached to the member B. A concave groove is formed on the surface of the member B, and a convex portion (B) is provided on the member A. The convex portion (B) is fitted into the concave groove and fixed so as not to come off through an adhesive. Yes. Without the adhesive, the member A cannot be fixed so as not to come off. In order to obtain such a mounting structure, the surface of the member B must be grooved, and the member A must be provided with a convex portion (b). For this purpose, the number of processing steps is increased and a material having a large size is required.

Accordingly, a narrow slit groove is provided in the wooden base material and the wooden member to be attached, and the joint material can be fitted over the slit groove so as to be attached. Moreover, it is stably and firmly fixed without using an adhesive.
Even if the width dimension of the slit groove is slightly different, the protrusion claw provided on the base surface is bent and deformed and fitted into the slit groove, and the joint material is fitted and attached without rattling, and one wooden member is attached. It will not come off the other wooden member.

And since a joint material is a product made from hard resin, when an impact acts on the wooden member to which it is attached, the protrusion claw of this joint material can bend and change, and also has an effect which absorbs an impact.
As described above, the wooden member is attached to the other wooden member via the joint material, but the joint material does not surface, and the workability is improved as compared with conventional nailing and screwing.
