In addition, when vibration such as an earthquake occurs, the receiving portion of the support and the fitting portion of the main body tend to move in the sliding direction with each other, but since the support or the main body is provided with the holding portion, the support is provided. The main body can be prevented from being pulled out from the main body.

According to a third aspect of the present invention, the receiving portion comprises a groove or a ridge, and the fitting portion includes a ridge or a groove engaged with the groove. The engagement is performed in a sliding manner by the ridges and grooves provided on the receiving portion and the fitting portion, and the operator slides the main body from above into the support attached to the pillar to use a special tool. The joining device can be easily formed without using it, and can be easily handled by anyone, and the efficiency of the work of attaching the joining device can be improved. Also,
When a load is applied from the main body supporting the beam to the fitting portion of the main body and the receiving portion of the support, even if a load is applied to the main body by the ridges and grooves provided in the fitting portion and the receiving portion. The main body can be prevented from detaching from the tool.

Further, according to the apparatus for joining building structural materials according to claim 4, the support is integrally fixed with a connecting plate interposed between the wall side plate and the parallel plate, and the connecting member is connected to the wall side plate and the parallel plate. Assuming that the size of the plate is smaller than the size of the parallel plate, an inverted U-shaped gap groove is formed on the peripheral side of the wall side plate and the parallel plate, and the fitting portion of the main body is substantially perpendicular to the insertion plate. By forming a notch groove corresponding to the size of the connecting plate in the substrate, the support member and the main body are made of a material such as a steel plate having the same thickness. Effective use can be achieved, and since the main body fits tightly to the support with no gap when the fitting part is inserted into this connector, there is no wobble with the support, As a result, the beam is firmly fixed to the column as a result of the secure holding force. In addition, the structure of the support is extremely simple and the manufacturing cost is low. In addition, the plate-shaped support can reliably support the main body as a separate body having the mounting and receiving portion and the pin hole. It is possible to secure.
