FLOOR STRUCTURE OF BUILDING FOR INSULATION AND NOISE INTERRUPTION

摘要

A floor structure of a building for preventing noise between floors is provided to insulate noise by installing an insulation board over a concrete slab, to mount a hot water pipe easily by adjusting the height of the insulation board with a shock absorbing damping unit, and to insulate heat and absorb shock by mounting an insulation sheet on the insulation board. An insulation board(11) is installed over a steel concrete slab(10), and plural height adjustable shock absorbing damping units(20) are installed in a lower part of the insulation board. A hollow(12) of about 20 to 50 mm is formed between the insulation board and the steel concrete slab with double floor structure. An insulation sheet is mounted on the insulation board, and formed by sequentially attaching an embossed EVA resin pad(31), a Styrofoam board(32) and a sponge pad(33). A cement mortar(50) including heating hot water pipes(40) and a surface finishing layer(60) are arranged on the insulation sheet. The insulation board is made of a wood wool concrete board or magnesia board.
