Abstract

The invention provides an integral system integrated with roof heat preservation and water resistance and a construction method thereof. The construction method is as follows: cleaning the substrate, and having slope-making or leveling treatment for needed roof; preparing polymer cement waterproof mortar scraped on the roof substrate as a first waterproof layer with the thickness of 2 to 5 mm; preparing rubber powder poly-phenyl granule cement mortar scraped on the first waterproof layer as an insulating layer with the thickness of 20 to 50 mm; preparing polymer cement waterproof mortar scraped on the insulating layer as a second waterproof layer with the thickness of 2 to 5 mm; preparing polymer cement anti-crack mortar scraped on the second waterproof layer, paving alkali-proof glass fiber gridding cloth, and then scraping the polymer cement anti-crack mortar once as a protective layer, and the thickness of each polymer cement anti-crack mortar is 1 to 2 mm. The roof substrate, the polymer cement waterproof mortar and the polymer cement anti-crack mortar are taken as cement base materials, and materials of cement, sand, and the like are also contained in rubber powder poly-phenyl granule insulating mortar, so the base material, the waterproof layer, the insulating layer and the protective layer have fine matching and bonding performances and perfect system stability.

Description

technical field [0001] The invention relates to a roof structure and a construction method thereof, in particular to a roof thermal insulation and waterproof integrated system and a construction method thereof. Background technique [0002] Building energy conservation has gradually been paid attention to due to the increasing shortage of energy sources. Roof surface insulation is an important part of it, because roof surface insulation can prevent the temperature in the building, especially the top floor, from changing too much with the ambient temperature, so that it does not need to be highly dependent on indoor temperature. The cooling and heating system works to maintain the indoor temperature suitable for human life, so as to achieve the purpose of energy saving. For each structural part of the house, thermal insulation and energy-saving measures have been well promoted and applied. The most common method of roof insulation is generally: leveling layer + waterproof la...
