SUPPORT LEG FOR BUILDING STRUCTURE AND DOUBLE FLOOR STRUCTURE
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
【課題】衝撃や生活音などを高度に防振・遮音することが可能な建造物用支持脚及び二重床構造を提供する。【解決手段】本発明の建造物用支持脚は、板片に高度制振緩衝材が設置された建造物用支持脚であって、前記高度制振緩衝材は、ポリオール成分と有機ポリイソシアネートとを混合させ硬化させたポリウレタン樹脂を含み、該ポリウレタン樹脂は、前記ポリオール成分の合計量を１００重量部とした時、官能基数２．４〜３．０、分子量３０００〜６０００のポリオールを９９．５〜９０重量部と、２級若しくは３級の高級モノアルコールを０．５〜１０重量部と、所定の安定剤を１．０〜４．０重量部、含有し、前記ポリウレタン樹脂の損失係数ｔａｎδが０．２以上であることを特徴とする。【選択図】 図３
