The present invention is intended to solve such a problem, and it is an object of the present invention to make it possible to easily connect a column to a horizontal member and to make it prefabricated.

[0005]

In order to solve this problem, the present invention provides a structure for connecting a lower end or an upper end of a pillar in a wooden building to a horizontal member such as a base or a beam that abuts on the lower end or the upper end. There, a recess is formed on the lower end surface of the pillar or on the lower surface of the horizontal member mounted on the pillar, and a recess is formed on the upper surface of the horizontal member or the upper end surface of the pillar at the position where the pillar is mounted,
The lower end surface of the pillar or the concave portion formed on the lower surface of the horizontal member mounted on the pillar and the concave portion formed on the upper surface of the horizontal member or the upper end surface of the pillar at the position where the pillar is mounted are provided with portions having the same shape as these concave portions. A connecting member provided with halves is fitted into the connecting member, and at least one corner of the upper end and the lower end is tapered to form a constricted portion, and horizontal portions are formed at upper and lower ends of the connecting member. Confirm that the through hole provided in the direction matches the pin insertion hole formed in the horizontal member and the pillar, and insert the pin from the pin insertion hole into the through hole to fasten the horizontal member and the pillar. It is a summary.

[0006]

With this structure, at least one of the upper end and the lower end of the connecting member is tapered to form the constricted portion, so that the connecting member can be easily aligned with the recess. The connecting member and the pin can easily connect the column and the horizontal member. Therefore, it is not necessary to hit the mortise with a hammer to fit the tenon into the mortise to connect the pillar and the horizontal member, and the pillar and the horizontal member are unitized at the factory. Pillars and horizontal members can be easily assembled at the construction site, enabling prefabrication. Also,
Reinforcing metal fittings for connecting pillars and horizontal members are not required,
As a result, it is not necessary to drive a large number of nails to fix the reinforcing metal member to the pillar and the horizontal member, and the assembly can be simplified.
