example 1

[0020] Example 1. Combining the attached figure 2 The structure and construction method of the thermal insulation roof of the present invention are further described: the reinforced concrete roof slab (2) is an internal plastering layer (1), and the floor slab (2) after construction is divided into slags to find slopes (slope 2%) , then select plastic cloth to spread on the slag slope to form an air barrier layer (3), then dry-lay expanded perlite 40mm thick to form a dry layer (8), then cover the first shell layer of expanded polystyrene (4a ) (thickness of the shell plate is 5 to 8mm, and the height of the shape is 80mm), so that the foot (4c) of the supporting shell layer is in contact with the plastic cloth, and the polyphenylene magnesium cement composite foam is cast on the first supporting shell layer (4a). Foam material (the inventor has applied for a patent, the application number is 02133070.0) and scraped to form the first cast-in-place layer (6a), and the first ai...

[0021] Example 2. Combining the attached image 3 The composition and construction method of the heat-insulating roof of the present invention are further described:

[0022] Below the reinforced concrete roof slab (2) is an internal plastering layer (1). Paint the emulsified asphalt oil 0.5mm thick on the roof slab (2) after construction to form an air barrier layer (3), and then cover the first shell layer (4a) of expanded polystyrene (thickness 5-8mm) , appearance height 60mm), let the foot (4c) of the first supporting shell layer (4a) contact with the air barrier layer (3), and cast polystyrene cement composite foam on the first supporting shell layer (4a) Foam material (the inventor has applied for a patent, the application number is 03134154.3) and scraped off to form the first cast-in-place layer (6a). Form the first air interlayer (5a) below its first supporting shell layer (4a), and close it by the separation seam, repeat the above-mentioned operation on the first c...

Abstract

An in-situ cast multi-layer roof with thermal insulation and air isolation functions is composed of internal plastered layer, surficial water-proof layer, an air isolating layer spread on the floor of roof, a shell supporting layer on the air isolating layer, in-situ cast insulating layer on said shell supporting layer, another shell supporting layer on said in-situ cast layer, and another shell supporting layer on said another shell supporting layer. Its construction method is also disclosed.

Description

technical field [0001] The invention relates to a roof building structure, in particular to a heat-insulating and heat-preserving multi-layer composite structure roof with air interlayers and a construction method. Background technique [0002] At present, the energy consumption of buildings in various countries in the world accounts for a very important proportion of the total energy consumption of the country. According to statistics, building energy consumption in developed countries in Europe and the United States generally accounts for 30% to 40% of the total energy consumption in the country, and my country's building energy consumption is 2 to 3 times higher than that in developed countries in Europe and America. The energy consumption of building roofs accounts for 20% to 25% of building energy consumption. Therefore, improving the energy-saving technology of roofs has become a crucial technical issue in building construction. [0003] For the structure of roof heat...
