Abstract

The invention discloses an assembly type overhead thermal insulation and sound insulation board for a floating construction floor and a preparing method of the assembly type overhead thermal insulation and sound insulation board. The assembly type overhead thermal insulation and sound insulation board comprises a quick-hardening cement mortar layer (1), an overhead load-bearing reinforced concreteboard (2), and a foam polyurethane layer or an inorganic mineral fiber thermal insulation and sound insulation material layer sprayed on the back side of the overhead load-bearing reinforced concreteboard (2). The overhead load-bearing reinforced concrete board (2) comprises supporting legs (2-1) at the bottom and a reinforced concrete board (2-2), wherein reinforcing mesh or mesh cloth is arranged in the reinforced concrete board (2-2). The assembly type overhead thermal insulation and sound insulation board is reasonable in structural design, has load bearing, thermal insulation, sound insulation, damping and other performance, is not prone to cracking, convenient to construct, little in dust, high in environmental friendliness and remarkable in comprehensive benefit, is manufactured in a factory and subjected to dry-type operation on site, and can improve the labor productivity, save lots of labor and management cost, greatly shorten the construction cycle and promote the assemblytype development of the floating construction floor.

Description

technical field [0001] The present invention relates to a building material, in particular to a prefabricated overhead heat insulation and sound insulation panel for floating floor slabs, which has the properties of load bearing, heat preservation, sound insulation, vibration reduction, etc., and is convenient in construction, strong in environmental protection, and has a wide range of applications. Background technique [0002] The indoor environmental quality of household floor slabs requires the comprehensive promotion of thermal insulation and sound insulation technology for floating floor slabs. As the thermal insulation and sound insulation material of the floating floor slab, the surface layer adopts artificially poured reinforced concrete protective layer. After more than one year of market practice, it has been proved that there are weak bonds between flexible panels and fine stone concrete, as well as manual wet work on site, and the construction quality cannot be ...
