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

Abstract

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 <2> 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)].

Description

technical field [0001] The invention relates to a construction method, in particular to a passive building flat roof thermal insulation and waterproof system and a partitioned dry operation construction method, belonging to the technical field of construction. Background technique [0002] With the development of the economy and the progress of the society, people have higher and higher requirements for the quality of the living environment. At the same time, under the background of the country's vigorous advocacy of low-carbon economy, passive ultra-low energy buildings are developing rapidly. [0003] At present, most building roofs use inverted roofs, which are widely used in civil buildings because of their simple structure, convenient and quick construction, and convenient maintenance. However, the insulation layer of the inverted roof is prone to water ingress and loses its thermal insulation performance. The waterproof material is soaked in water for a long time, caus...
