Description

Earthquake-Reinforced Brackets {EARTHQUAKE-PROOF REINFORCING ATTACHMENT}

The present invention relates to a seismic reinforcement bracket for reinforcing between a foundation and a foundation or a pillar thereon at a corner joint of a building structural material so that there is no fear of collapse even when a high vibration is applied to a wooden building by an earthquake or typhoon.

Conventionally, the method of fixing between the base of a wooden building and the base on it using an anchor bolt, and fixing the corner junction of the said base and a pillar using an L-shaped bracket etc. are conventionally employ | adopted.

However, according to the reinforcement method described above, when a high vibration is applied due to an earthquake, a typhoon, or the like, the building structural material may fall off or break at the corner joint where the impact is concentrated. There was concern about damage to the wooden structure.

For example, a reinforcing bracket 61 as shown in FIG. 6 is generally used.

In other words, the reinforcing bracket 61 is formed by fixing the plate pieces made of high-strength steel in a L-shaped angle by 90 degrees to form fixing pieces 61a and 61b provided with bolt holes. The piece 61a is fixed to the base angled member 6x using the anchor bolt 62, and the other fixing piece 61b is fixed to the column 6y by means of fixing means 63 such as bolts or nails. It fixes and reinforces the junction part of the base angled member 6x and the pillar 6y.

Restoration with the angled member 6x and the junction portion a-1 between the stationary piece 61a or the junction portion b-1 between the column 6y and the stationary piece 61b falling off or damaged due to breakage. Problems such as not being easily prone to occur, so that the reinforcing effect is not enough, there was a fear that the wooden building is destroyed or collapsed.

The present invention has been made to solve the problems seen in the conventional reinforcement brackets, and absorbs the displacement caused by the vibration in the vertical and horizontal directions so as not to collapse even when the wooden building vibrates greatly due to an earthquake or typhoon. It is intended to provide a seismic reinforcement bracket for improving the seismic performance by providing a restoring function.
