DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-seismic member used as an anti-seismic wall in order to enhance the anti-seismic performance of a building.

[0002]

2. Description of the Related Art Conventionally, in order to improve the seismic performance of a house according to, for example, a wooden frame construction method, it has been generally practiced to attach braces or earthquake-resistant walls to a frame composed of columns, beams and the like.

[0003]

However, bracing and conventional shear walls resist external forces acting in a direction parallel to the construction surface, but hardly resist external forces acting in a direction perpendicular to the construction surface. Can not do it. Therefore, in order to enhance the seismic performance of a building by using braces or conventional shear walls, it is necessary to arrange braces or shear walls in a balanced manner in both the XY directions of the building plane. Placement may be difficult.

[0004] Further, since the bracing and the conventional earthquake-resistant wall are of a fixed size, it takes time to adjust the dimensions thereof. For example, replacing a brace or a shear wall attached to a certain frame with another frame of a different size requires time and effort such as cutting the brace or the shear wall.

Therefore, the present invention has been made in view of such a problem,
It is an object of the present invention to propose a seismic member capable of easily adjusting the dimensions while being able to easily resist external forces in two orthogonal directions.

[0006]

That is, according to the first aspect of the present invention, a unit structure formed by combining and fixing two face plate members in a T-shaped cross section is formed by a web in one unit structure being adjacent to the unit structure. A seismic member characterized by being vertically attached to the back surface of a flange of a unit structure to be fitted and being connected in the same direction so that the flange projects in a vertical rib shape or a horizontal rib shape. It is.

When such an earthquake-resistant member is used particularly as an earthquake-resistant wall, each web of the unit structure serves as a resistance element against an external force in the X direction (Y direction), and each flange orthogonal to the web has a Y direction ( Since it functions as a resistance element against an external force in the (X direction), it can itself resist external forces in both the XY directions. Further, since the seismic member has a configuration in which a plurality of unit structures are connected, the size of the seismic member can be easily adjusted only by changing the number of connected unit structures.

According to a second aspect of the present invention, there is provided an anti-seismic member characterized in that the anti-seismic member according to the first aspect is formed in a panel shape by being sandwiched between two side plates from both sides.

In such an earthquake-resistant member, since the unit structure is reinforced by the side plates on both sides, the earthquake-resistant performance of the entire earthquake-resistant member is further improved. Moreover, since it is configured in a panel shape, handling is easy and workability is improved.

According to a third aspect of the present invention, there is provided an earthquake-resistant member characterized in that a frame member is fixed to the four circumferential end faces of the earthquake-resistant member according to the first or second aspect.

In such an earthquake-resistant member, since the unit structure is reinforced by the frame material on the four circumferential end faces, the earthquake-resistant performance of the entire earthquake-resistant member is further enhanced. In addition, the frame material on the four circumferential end surfaces facilitates attachment to the frame, and improves workability.
