The invention discloses a passive building flat roof heat preservation and water prevention system which is composed of a steam isolation layer, a heat preservation layer, a self-adhesion waterproof layer and a hot melting waterproof layer which are arranged on a concrete base layer. A construction method comprises conducting construction preparation, brushing an interface agent, mounting drain lower fitting, conducting vapor barrier construction, conducting planar thermal insulation layer pavement, conducting planar adhesive coil material construction, conducting vertical face heat preservation layer construction, mounting a drain gully upper accessory, paving and pasting a vertical surface self-adhesive coiled material, and conducting hot-melt coiled material construction. The waterproofperformance of the roof is improved; the drying of the heat preservation layer can be effectively ensured; the quality is not influenced by cloudy and rainy weather; the construction is simple; joints are easy to process; the construction speed is high, and the roof of 1000 m is taken as an example, the construction period is shortened by 15 days compared with that of traditional roof construction; the manufacturing cost of the passive building flat roof heat preservation and waterproof system is 30% lower than that of a common roof, an SD value is larger than or equal to 1500 m, and a heat conductivity coefficient is smaller than or equal to 0.015 [W/(m.K)].

Passive building flat roof heat preservation and water prevention system and partitioned dry operation construction method

The invention relates to a passive ultralow-energy-consumption dry operation roof heat insulation and waterproof integrated construction method, and aims to solve the problem of poor heat insulation performance in the prior art. The method sequentially includes the roof heat insulation and waterproof construction steps: (1) sloping and leveling a roof to form a clean and dry concrete structure base layer with slope larger than 2%; (2) brushing the dry concrete structure base layer in the previous step with cold primer oil to form a cold primer oil base layer treatment layer; (3) mounting a self-adhesion acid and alkali resistant aluminum foil surface modified asphalt disconnecting rolling layer on a coated profiled steel sheet base layer or the cold primer oil base layer treatment layer inthe previous step by cold self-adhesion; (4) mounting a heat insulation layer on the self-adhesion acid and alkali resistant aluminum foil surface modified asphalt disconnecting rolling layer in an adhered manner by polystyrene foam; (5) adhering a self-adhesion fireproof modified asphalt waterproof rolling layer on the heat insulation layer; (6) welding a pavement surface layer slate surface waterproof rolling layer on the self-adhesion fireproof modified asphalt waterproof rolling layer in a hot-melting manner by a blow lamp. The method has the advantages of light self-weight, rapidness andconvenience in construction and good heat insulation performance.
