Energy-saving and environment-friendly type waterproof and thermal preservation construction method of existing roof

Abstract

The invention discloses an energy-saving and environment-friendly type waterproof and thermal preservation construction method of an existing roof. The method comprises the steps of crack resistant and waterproof mortar spraying, spraying exposed waterproof layer with a base course interface agent, polyurethane rigid foam spraying, first-time self-inspection and acceptance, butyl rubber waterproof paint and three-in-one self-adhesion waterproof protection coiled material composite construction, second-time self-inspection and acceptance, uvioresistant waterproof paint protection layer spraying and third-time self-inspection and acceptance. The energy-saving and environment-friendly type waterproof and thermal preservation construction method of the existing roof has the advantages that the existing roof does not need to be removed for waterproof construction, system construction can be conducted directly, a thermal compound construction technology is conducted on the paint and the coiled material on the construction surface, it is guaranteed that after construction is conducted on the seamed coiled material, a seamless waterproof layer is formed, the uniformity of the coiled material effectively makes up the nonuniform phenomenon of the paint, thus to make the whole surface layer form an integrated seamless waterproof system, and energy conservation and environmental protection are achieved; the construction cost is low, the effects of the construction safety, waterproofing and thermal insulation are good, and the bearing quality of building design is not affected.

Description

technical field [0001] The invention relates to the field of waterproof construction, in particular to an energy-saving and environment-friendly waterproof and thermal insulation construction method with a roof. Background technique [0002] With the construction and development of China, high-rise buildings have sprung up all over the country, and there are many high-rise buildings. Urban congestion, energy conservation and environmental protection have become issues that everyone is concerned about. Waterproof thermal insulation roof is a kind of waterproof roof that integrates waterproof and thermal insulation. Waterproof is the basic function. [0003] The waterproof and thermal insulation layer of the roof in the traditional construction industry is mainly made of loose materials, such as slag, expanded vermiculite, expanded perlite and other materials. The existing problems are that the construction is difficult and the heat insulation effect is not ideal. In the roof...

Problems solved by technology

[0003] The waterproof and thermal insulation layer of the roof in the traditional construction industry is mainly made of loose materials, such as slag, expanded vermiculite, expanded perlite and other materials. The existing problems are that the construction is difficult and the heat insulation effect is not ideal.

In the roof construction of the existing house renovation currently implemented, it is necessary to remove the original waterproof layer of the roof, and then lay a new insulation layer (the insulation layer can be a loose material insulation layer, or a new type of heat insulation material aggregate. Styrene foam board), the protective layer used to protect the thermal insulation layer, and then lay a new waterproof layer, so that the paint is not evenly applied, not only the waterproof and thermal insulation effect is not ideal, the construction period is long, the construction is cumbersome, the overall cost is high, waterproof and thermal insulation Fires are prone to occur during construction, and it also causes resource waste and environmental pollution, which does not meet the national energy-saving and emission-reduction requirements for the construction industry
