SOUND INSULATION STRUCTURE OF DOUBLE FLOOR AND CEILING, AND BUILDING HAVING THE SAME
PROBLEM TO BE SOLVED: To solve the following problems: a sound insulation structure of a double floor conventionally makes the floor heavy, makes a manufacturing cost high, and makes workability of sound insulation work improper.SOLUTION: In a sound insulation structure of a double floor 1 made of a floor material supported by a support leg erected on a slab, one or more Helmholtz resonators 7, in which a communication hole 7b for communicating a hollow part 7a with the outside is provided in a part of a box body forming the sealed hollow part, are provided in an underfloor airspace 8 between the slab and the floor material.
【課題】本発明は、二重床の遮音構造に関し、従来において重量床になることと、製作コストが嵩み、遮音工事の施工性が良くないことが課題であって、それを解決することである。【解決手段】スラブ上に立設された支持脚で支持される床材で構成される二重床１において、前記スラブと前記床材との間の床下空気層８に、密閉された中空部を形成する箱体の一部に、前記中空部７ａと外部とを連通させる連通孔７ｂを設けてなるヘルムホルツ共鳴器７を、１以上設けてなる二重床の遮音構造とする。【選択図】図１
