Description

The present invention relates to a reinforcing member structure for wood joints.

Conventionally, as a reinforcing member structure for wooden joints, wood is used separately, such as joints between the foundation and through pillars of a wooden house, joints between beams and main pillars, and concentrated joints where various vertical and horizontal pillars are concentrated at one point. In a concentratedly joined structure, a metal reinforcing member that intervenes and connects each pillar is suspended to prevent them from separating from each other due to shaking such as an earthquake, thereby reinforcing reinforcement.

In addition, as a reinforcing member for other joints, a reinforcing metal fitting composed of an L-shaped channel material and a triangular plate material provided on the inner angle side forming a right angle of the channel material as described in Patent Document 1 is used. A reinforcing member is disclosed that reinforces the joints of the framework and fixes braces provided between columns using bolt holes drilled in triangular plates.

However, in the case of a structure in which multiple column members are joined intensively at one point, a reinforcing metal plate is installed between each column and the adjacent column, so the reinforcing structure is complicated and the strength is weakened accordingly. In addition, since it is necessary to prepare a large number of reinforcement members, it is disadvantageous in terms of cost, and furthermore, the reinforcement work is complicated and it is difficult to improve the strength.

In addition, in the reinforcing member described in Patent Document 1, since the same reinforcing member is used at any joint, the decision of how to attach the reinforcing member to the joint is left to the on-site craftsman. In addition, there is a possibility that the necessary earthquake resistance cannot be achieved depending on the mounting location and mounting condition of the reinforcing member.

In order to solve such a drawback, the present invention provides a divided case structure in which the member joint structure of the joint part of the wood is recognized in advance and the overall outer shape of the joint structure is divided into two or three joint split pieces such as left and right, top and bottom. Each of the plurality of divided case structures is formed as a single wrapping member, and the outer surface of the joint portion is entirely covered by the combination of the single wrapping member, and the single wrapping member is integrated to complete the reinforcement of the wood joint portion. We tried to eliminate the conventional drawbacks by constructing.

In order to solve the above conventional problems, the overall shape of the member joint structure of the joint part of the wood is recognized in advance, and the overall outer shape of the joint structure is divided into two or three split pieces such as left and right, top and bottom.

It becomes easy to determine the suitable split case body, and the necessary seismic strength can be achieved by correctly encapsulating the necessary places.

According to the invention of claim 2, each split case body has one or a plurality of cavities formed at predetermined locations to minimize the load stress on each split case body based on the eccentric load applied to the joint portion due to an earthquake or the like. Even if the stress caused by the shaking of the earthquake is received, the cavity is provided to release the force and prevent deformation as much as possible, thereby preventing the collapse of the house.

According to claim 3, the connecting and fixing structure of the split case bodies is constituted by abutting and fixing structure of the pair of flange pieces protruding alternately at the end edges of the split case bodies facing each other. In addition, since the connecting portion is less likely to move, the screw used for fixing to the wood is less likely to loosen.
