Roof heat preservation anti-leakage system and heat preservation anti-leakage roof structure using same

Abstract

The invention discloses a roof heat preservation anti-leakage system and a heat preservation anti-leakage roof structure using the system. The heat preservation anti-leakage roof structure comprises a roof layer and the roof heat preservation anti-leakage system covering the roof layer, wherein the roof layer is in the form of reinforced concrete precast slab, and the roof heat preservation anti-leakage system comprises an anti-leakage layer, a heat preservation layer and protection layers. The heat preservation layer is arranged above the anti-leakage layer, and the protection layers are adjacently connected with the anti-leakage layer and arranged at the upper and lower sides of the anti-leakage layer. The anti-leakage layer is a water-proof air-permeable sand layer and the heat preservation layer is a hollow heat-insulated water storage brick layer. The sand-based roof heat preservation anti-leakage system according to the invention integrates the functions of heat preservation, anti-leakage and beautification as well as has simple structure and low construction and maintenance costs.

Description

technical field [0001] The invention relates to the technical field of roof anti-seepage, in particular to a roof heat preservation and anti-seepage system and a roof structure applying the system. Background technique [0002] At present, the existing roofs of urban buildings in our country mostly adopt reinforced concrete prefabricated slab structures, which are mainly flat. Its anti-seepage material mainly adopts asphalt, for example, Chinese patent (publication number: CN87106092) discloses a kind of asphalt-containing roof layer, and roof layer contains a kind of covering material, and it is made up of a kind of asphalt / rubber mixture, and ratio is 17 / 3~19 / 1, when the roof layer is made, use between 6 and 16×10 4 The emission energy between Gy is radiated. Such a flat roof with asphalt as an anti-seepage material has the following disadvantages: (1) poor thermal insulation, greatly affected by outdoor temperature changes, cold in winter and hot in summer; (2) the roo...
