According to the conventional building structure described in Patent Document 1, it is possible to make the distance of the mounting body from the skeleton in the front-rear direction variable, and to prevent the mounting body from rotating and swinging with respect to the L formwork. In addition, after installation, the handrail unit can be firmly supported via the attachment body.

However, in the conventional building structure, since uneven grooves are formed on the outer surface of the U-shaped frame, depending on the setting position of the mounting body, the uneven grooves are exposed and visible. However, there is a problem that the design of the handrail is deteriorated. In addition, since the building structure has a large number of constituent members and a pair of L-shaped frames must be fixed to the frame, there is a problem that the work efficiency of constructing the handrail is inferior. In other words, there is a demand for a building structure that has a function as a pillar that maintains the strength of installed building members, has a good design, and can improve the efficiency of the work of installing building members. .

In order to solve the above-mentioned problems, a building structure according to claim 1 comprises a bracket and a member to be attached, and a concave portion is formed in either the bracket-side surface portion of the member to be attached or the surface portion of the bracket for fixing the member to be attached. An anti-slip member is stored in the recess, and an anti-slip portion is formed on the other of the surface of the mounting member on the bracket side or the fixing surface of the mounting member of the bracket to keep the anti-slip member in an immovable state. The bracket has a through-hole through which the fastener is inserted in the fixing surface portion of the attached member, and the attached member is attached to the bracket by the fastener.

With the above configuration, the present invention provides an architectural structure that has a function as a support that maintains the strength of the installed building members, has good design, and can improve the efficiency of the work of installing building members.
