Abstract

The invention discloses a leakage-proof construction method for building roofs. For the cracks at the building roof of prefabricated plate or cast-in-place structure, the method comprises the following steps of: cleaning the cracks by water; pouring an absorbent resin in the cracks by a high-pressure pump or mixing a sodium methane-siliconic alkoxide and a polyethylene by the weight ratio of 8:1 uniformly and filling the mixture in the cracks; coating a polyisobutene on the upper surface of the absorbent resin till the thickness being of 2-3mm; and covering the upper surface by a fiberglass cloth. For the leakage at the top of the building due to missing edge or corner and unevenness on the roof surface, the method comprises the following steps of cleaning up the roof surface, using a polyvinyl alcohol cement mortar, mixing the sodium methane-siliconic alkoxide as well as a water (8 weight parts) uniformly and spraying the mixed solution on the roof surface; mixing the sodium methane-siliconic alkoxide and water by the weight ratio of 1:8 uniformly and mixing the mixed solution with the cement mortar material by the weight ratio of 1:2 uniformly, and smearing the mixture on the roof surface till the thickness being of 8-12mm. The method has the advantages that the roof with the leakage supplemented has long service life ranging from 15 years to 25 years generally.

Description

technical field [0001] The invention relates to a building construction method, in particular to a building roof leak-proof construction method. Background technique [0002] Buildings, especially civil buildings, mostly use prefabricated panels or cast-in-place reinforced concrete flat roofs, so cracks often appear after a period of use, causing water leakage; or due to the micropores and capillaries formed during the hydration and hardening of roof cement holes resulting in leakage. For the above water leakage problem, the traditional leak prevention and repair methods mostly adopt the mode of scalding the roof surface with asphalt; the disadvantage of this method is that the service life is short, generally 3-5 years. Contents of the invention [0003] The object of the present invention is to provide a simple, feasible, environmentally friendly and hygienic building roof leak-proof construction method. [0004] To achieve the above object, the present invention can t...
