COMBINATION STRUCTURE OF HYBRID FRAME AND PLYWOOD OR CLT BOARD OR THE LIKE

摘要

PROBLEM TO BE SOLVED: To add a structure that enhances floor rigidity on a horizontal structural plane of a hybrid frame that combines an aseismic opening frame that bears seismic force (a horizontal load) and a lightweight section steel that bears a vertical load.SOLUTION: A combination structure of a hybrid frame and a plywood or a CLT board or the like includes a hybrid frame (1) and a plywood or a CLT board or the like as a floor material (8) bonded on a top surface of the hybrid frame (1) and integrated by a fastener, the hybrid frame including a horizontal material (40) of an aseismic opening frame (4) that has at least a pair of vertical materials (41) and the horizontal material spanned between top edges of the pair of vertical materials (41), an upper chord material (3) disposed at the same entire length above the horizontal material (40), and a pair of lightweight section steels (2) extending over at least the entire length of both of the horizontal material (40) and the upper chord material (3) and fastened on both side surfaces of both materials with a fastener.SELECTED DRAWING: Figure 2
