Column-beam structure

Abstract

The objective is to create a reusable column-beam frame structure while forming stepped sections in the beams. [Solution] The first precast joint member 30X has a first concrete column, a second concrete column whose upper surface is positioned higher than the upper surface of the first concrete column, a first concrete joint portion 40X that is detachably joined to the upper surface of the first concrete column, and a first steel beam bracket 50X that protrudes from the first concrete joint portion 40X toward the second concrete column, and a second precast joint member 30Y has a second concrete joint portion 40Y that is detachably joined to the upper surface of the second concrete column, and a second steel beam bracket 50Y that protrudes from the second concrete joint portion 40Y toward the first concrete column and whose upper surface is positioned higher than the upper surface of the first steel beam bracket 50X, and a beam member 60 that has a stepped portion 60S and connects the first steel beam bracket 50X and the second steel beam bracket 50Y.

Claims
