Description

Earthquake-Reinforced Brackets {EARTHQUAKE-PROOF REINFORCING ATTACHMENT}

The present invention relates to a seismic reinforcement bracket for attaching and reinforcing to a joint of a wooden member such as a foundation, a pillar, a purlin, and a girder so that a wooden building does not collapse even when subjected to a strong vibration caused by an earthquake or typhoon.

Background Art Conventionally, various methods have been adopted as a method of reinforcing a joint portion of a wooden member of a wooden building, such as designing a reinforcing reinforcement member or an angle beam, or attaching a cramp or an L-shaped bracket.

However, in the conventional method, when a strong vibration is caused by an earthquake or typhoon, the reinforcing effect is not sufficient, and the structural material simply falls off or breaks at the joint, or the wooden condition is destroyed at the joint or, in severe cases, collapses. There was a case.

Therefore, the seismic reinforcement brackets 51 are devised and used as shown in Fig. 4 to sufficiently withstand the strong vibrations caused by earthquakes, typhoons and the like.

The seismic reinforcing bracket 51 bends a plate made of high-strength steel in an L shape and bends inwardly bent inward to the middle portions of the two side portions 52a and 52b. The L-type base material 52 which provided 53a, 53b was provided, and the reinforcement member 54 which bent the board | plate material which consists of high tensile strength steel was fixed to the bending angle part 52c of this L-type base material 52 by welding, The shock absorbing member 55, such as rubber | gum, was hanged in various places of the L-type base material 52. As shown in FIG.

Thereby, strong vibration in the vertical and horizontal directions can be absorbed by the entirety of the L-type base material 52 and its bent and expanded portions 53a and 53b, and the deformation of the L-type base material 52 is prevented by the reinforcing member 54. Since it can be restored, even if subjected to strong vibration, the wooden building is not easily broken or collapsed at the joint.

However, the above-described earthquake-resistant reinforcing bracket 51 is a flat bending expansion portion 53a, 53b by bending the middle portions of the two pieces 52a, 53b inward to absorb the vibration in the vertical direction and the fluctuation around the vertical. Was not enough.

In addition, since the reinforcing member 54 is fixed to the L-type base material 52 by welding, the bending angle part 52c of the L-type base material 52 and the bending angle part 54c of the reinforcing member 54 are in close contact with each other. The amount of elastic deformation was small and the effect of restoring the deformation of the L-type base material 52 was not sufficient.

Furthermore, since the reinforcing member 54 is fixed and attached, the fastening bolts may be blown or the reinforcing member 54 itself may be caused by excessive load or stress concentration on each part of the reinforcing member 54. Or a crack is generated in the reinforcing member 54.

The present invention is to solve this problem, further improves the effect of absorbing the vibration in the vertical direction, the fluctuation around the vertical, further improves the effect of restoring the deformation of the L-type substrate, and also fastening bolts, reinforcement The object of the present invention is to provide a seismic reinforcement bracket which further improves seismic performance so that the structure itself does not collapse even when subjected to strong vibrations such as earthquakes, typhoons, and the like, by at least suppressing the occurrence of springs or cracks in the reinforcing members. It is done.
