Description

The present invention, when building a building such as a house, office, store, factory, etc., is a building that is attached to a foundation provided on the foundation of the building or a foundation formed on the foundation and becomes a part of the building structure It relates to a reinforcement object.

Conventionally, as a method of building a house using a steel frame, a mounting plate for connecting to the foundation is provided at the lower end, and a mounting plate for connecting to the beam material is provided at the upper end. A flat base material in which the upper and lower sides and the middle part of the square pipe are connected so that one side surface is located on the same plane by a horizontal member made of a square member and a reinforcing oblique member, and an attachment for connecting the base to the lower end A horizontal member made of a square member and a reinforcement at the upper and lower and middle parts of a square pipe that becomes three pillars of 2.3 to 3.5 m each provided with an attachment plate for connecting the plate with a beam member at the upper end. It is intended to construct a right-angle base material in advance by standardizing and manufacturing a right-angle base material that is bent at a right angle in plan view and connected so that the outer surface is located on the same plane. In the corner of the house, place the flat substrate on the flat part of the house Place the partition portion, the lower portion connected by underlying, upper is disclosed to form a shaft set as a whole house by coupling the beam member (e.g., see Patent Document 1).

Japanese Patent No. 2121986

However, in the flat base material and the right-angle base material described in Patent Document 1, the mounting plates provided at the upper end and the lower end of the opposing square pipe are not connected to each other, and both ends of the opposing square pipe are not connected. The side has the problem of low resistance to deformation. Moreover, since the reinforcement diagonal member is arrange | positioned between each opposing pipe, an opening part cannot be provided inside a plane base material and a right-angle base material, and the problem that a use arises also arises.
In addition, the right-angle base material does not have a mechanism for maintaining the angle formed by the horizontal members connecting the square pipes positioned at the right-angle corners and the square pipes arranged on both sides thereof at 90 degrees. The corner shafts cannot be formed based on the right-angle base material, and the accuracy of the corners of the shafts is determined in the process of forming the shafts of the entire house as in the prior art. Further, even if a shaft assembly is formed using a right-angle base material, a special effect that the deformation of the corner portion of the shaft assembly can be prevented.

The present invention has been made in view of such circumstances, and is attached to a foundation provided on a foundation of a building or formed on the foundation, thereby improving the accuracy of the building structure, improving the deformation resistance, and increasing the strength.
