COMPOSITE MATERIAL FOR BUILDING, AND FLOOR STRUCTURE AND FLOOR CONSTRUCTION METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a composite material for building combining excellent structural characteristics of metal members and excellent vibration performance of wood members while minimizing the increase of a material cost and making the most of the properties and characteristics of wood, and to provide a floor structure or a floor construction method having high structural stability and excellent habitable sound performance using the composite material for building or its components. SOLUTION: The composite material 1 for building is formed by fixing a wooden material 10 in close contact to the longitudinal direction of at least a face on which a floor face material abuts, of an outer surface of the metal member 2 formed in closed cross section. The floor structure is constituted by joining the end of the composite material 1 for building to a wooden beam member perpendicularly to the wooden beam member. COPYRIGHT: (C)2005,JPO&NCIPI
