METHOD FOR MANUFACTURING BOTTOM STRUCTURE BETWEEN FLOORS OF BUILDING USING POROUS MATERIAL FOR INSULATION AND ABSORPTION OF SOUND, METHOD FOR MANUFACTURING SIDE WALL STRUCTURE OF BUILDING USING THE SAME

摘要

A method for manufacturing bottom structure between floors of building using porous material for insulation and absorption of sound and a method for manufacturing side-wall structure of building using the porous material are provided to install excellent insulation against heat and sound while reducing a manufacturing cost by using porous materials having light weight and higher strength for construction. A method for manufacturing bottom structure between floors of building using porous material for insulation and absorption of sound and a method for manufacturing side-wall structure of building using the porous material comprise steps of: preparing a mixture for porous material for insulation and absorption of sound comprising steps of: a) preparing main material comprising vermiculite powder, perlite powder, coal material and materials emitting far-infrared rays; blowing additive comprising at least one metal powder blowing agent selected from aluminium powder and zinc powder, at least one blowing catalyst selected from slack lime, quick lime and sodium bicarbonate; at lest one blowing stabilizer selected from crystalline cellulose and carboxymethylcellulose; at least one coupling agent selected from kaolin and bentonite; and at least one ionic coagulating agent selected from montmorillonite and calcium chloride; and b) mixing the prepared main material, blowing additive, coupling agent, ioinc coagulating agent and water; and casting and curing the mixture for porous material for insulation and absorption of sound on the concrete slab whereby forming porous material for insulation and absorption of sound. For manufacturing side wall structure of building using the porous material, a heating pipe laying is located on the porous material for insulation and absorption of sound, and a finishing mortar is formed on the heating pipe laying. The main material is contained in the amount of 78-95% by weight, the blowing additive is contained in the amount of 1-15% by weight, the coupling agent is contained in the amount of 1-5% by weight, and the ionic coagulant is contained in the amount of 1-4% by weight with respect to the total weight.
