2. Description of the Related Art Conventionally, a plate or the like is often attached to a through pillar, a base, and a base of a wooden frame structure building in order to prevent the through pillar from being pulled out or twisted. The base and the base may have anchor bolts in the vertical direction to fix the base to the base. However, plates and the like have some degree of protection against pull-out and torsional forces on through columns, bases and foundations caused by swaying and swaying caused by aging and vibration, especially large vibrations due to earthquakes, etc. However, the effect of preventing the torsion caused by a stronger pull-out force or a compressive force from another direction was relatively weak. Further, the through pillar, the base, and the base are not connected in series, but the through pillar, the base, and the base and the base are separately fixed. In addition, since the area of the contact connecting the through pillar and the base is small, it was difficult to obtain a sufficient effect for preventing the through pillar from being pulled out or twisted. In addition, since the plate or the like is attached with only the nail or the small screw, the nail or the small screw itself has a problem that the pull-out and the torsion force applied to the through column and the base easily cause the pull-out. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is caused by swaying or swaying caused by aging or vibration, particularly large vibration caused by an earthquake or the like. This is a device to reinforce the prevention of pull-out and twisting of through columns, foundations and foundations in wooden framed structures, and only one strip-shaped plate material against pull-out and twisting force of through columns. Rather than a strip-shaped plate having a brace portion on a plate, a surface and a thickness are formed by connecting another strip-shaped plate, and have the same prevention effect strength as in the case of a box having a surface and sides. It is a connecting plate, and the head of a lag screw bolt passed through a strip-shaped plate material having a brace part on the plate material is pressure-fixed with another strip-shaped plate material to prevent pulling out of the lag screw bolt. To, the continuous columns and the base and the base portion of the wooden framework structure building, and to provide a reinforcing device of the connecting plate as its purpose.
