[Problems to be solved by the device]

 However, the connection between the pillar 1 and the horizontal member 3 having the above-described structure is performed by fitting the tenon 2 of the pillar 1 and the mortise hole 4 of the horizontal member 3, so that the horizontal member 3 can be easily fitted. If the mortise 4 is made larger than the mortise 2, rattling occurs between the column 1 and the horizontal member 3, resulting in an unstable structure as a frame structure. Therefore, it is necessary to fit the mortise 2 into the mortise hole 4 without any gap, and in this case, the external force is applied by hitting with a hammer or the like. As a result, it is difficult to assemble the pillars 1 and the horizontal members 3 at a factory or the like, and it is difficult to easily assemble the pillars 1 and the horizontal members 3 at a construction site. Further, it is necessary to prepare a reinforcing metal fitting 5 for connecting the pillar 1 and the horizontal member 3 and to drive a large number of nails 6 to fix the reinforcing metal member 5 to the pillar 1 and the horizontal material 3. There was a problem that it took time to work.

The present invention solves such a problem, and an object thereof is to make it possible to easily connect a column and a horizontal member, and also to enable prefabrication.
