BRACKET WITH IMPROVED TENSILE STRENGTH AND EARTHQUAKE-PROOF PERFORMANCE, AND CONNECTION MEMBER USING SAME

WIPO Patent Application WO/2022/131513

A1

The present invention relates to a bracket with improved tensile strength and earthquake-proof performance, and a connection member using same. To this end, the present invention provides a bracket, comprising a first fastening piece in which slit-shaped fastening holes are formed in a first direction and a second fastening piece which is integrally formed to be perpendicular to the first fastening piece so that a fastening means can be selectively fastened, wherein a plurality of serrations are formed, on one surface of the first fastening piece, to be orthogonal to the slit-shaped fastening holes formed in the first direction, and each of the serrations has a concave cross-section having a predetermined curvature toward the slit-shaped fastening hole. Thus, since the serrations having the concave cross-section and formed on the bracket and the serrations having the convex cross-section and formed on a washer are pressure-fastened by bolts in a state of being in contact with each other, sufficient tensile strength can be ensured, and since the serration having a curvature can tolerate a part of the displacement even in the orthogonal direction, there is an advantage that the multidirectional displacement can be tolerated.
