SUPPORT LEG FOR BUILDING STRUCTURE AND DOUBLE FLOOR STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a support leg for building and a double floor structure capable of insulating vibration and noise such as impact or life sound at high level.SOLUTION: The support leg for building is a support leg for building with high level vibration-proof cushioning material arranged on a plate piece, where the high level vibration-proof cushioning material contains a polyurethane resin by mixing and curing a polyol component and organic polyisocyanate, the polyurethane resin contains polyol having functional group number of 2.4 to 3.0 and molecular weight of 3000 to 6000 of 99.5 to 90 pts.wt. and binary and tertiary higher monoalcohol of 0.5 to 10 pts.wt. and a predetermined stabilizer of 1.0 to 4.0 pts.wt. and loss coefficient tan δ of the polyurethane resin is 0.2 or more based on 100 pts.wt. of total amount of the polyol component.SELECTED DRAWING: Figure 3
