Building waterproof heat-preservation exhaust compound system and construction method thereof

Abstract

The invention relates to a building waterproof heat-preservation exhaust compound system, which comprises a heat-preservation layer, a waterproof layer, a waterproof protective layer and an exhaust passage, and is characterized in that the heat-preservation layer comprises paved heat-preservation boards, the lower surfaces of the heat-preservation boards are provided with exhaust grooves, the exhaust grooves of all the heat-preservation boards are connected into the exhaust passage, one end of the exhaust passage is connected into a flue through a connecting pipe, and the waterproof layer and the waterproof protective layer are covered on the heat-preservation layer in turn. The building waterproof heat-preservation exhaust compound system has the following advantages that: the system is a heat-preservation waterproof moisture-proof exhaust system for roofs and the floors, which uses a JWG-M type to seal and resist water for EPS and XPS heat-preservation boards, is communicated with the flue through the exhaust grooves of the EPS and XPS heat-preservation boards, and exhausts moist air in time by the pipeline effect of the flue so as to achieve waterproof heat-preservation exhaust integral roofs. Simultaneously, the system removes the vertical exhaust pipes arranged on the roofs and reduces the hidden danger of seepage, and the roofs are smooth to prevent frost heave and gas heave so that the deserved effective service life of the waterproof and heat-preservation roofs is achieved. Besides, the system has good heat-preservation and waterproof effects.

Description

technical field [0001] The invention belongs to a building waterproof and thermal insulation technology. Background technique [0002] At present, the waterproofing and heat preservation of the roof mostly adopts an insulation layer on the roof cement prefabricated board, and then a waterproof layer is covered on the insulation layer. The insulation layer on the roof surface is mostly made of laying insulation panels or cast-in-place cement expanded perlite. Among them, the laying of insulation panels leaves more water storage space in the insulation layer of the roof surface, and at the same time, condensation at the interface between insulation materials and other materials (such as leveling layers) is difficult to avoid. For the insulation layer of cast-in-place cement expanded perlite, the water absorption rate of cast-in-place materials (such as expanded perlite) is too large. Excessive water content and water storage rate of the slope formation and insulation layer w...
