An anti-leakage construction method for external doors and windows of above-ground external thermal insulation walls

Abstract

The invention particularly relates to an anti-leakage construction method for an outer door and a window edge of an outer heat insulation wall on ground. The anti-leakage construction method is characterized by comprising the following steps of installing an outer door or outer window auxiliary frame on a wall at a base layer, and filling a gap by waterproof mortar; installing an outer door or outer window main frame, sealing a gap by waterproof sealant, and covering the waterproof mortar onto the outside of the waterproof sealant to realize sealing protection; constructing a leveling layer on the wall at the base layer; brushing waterproof coating on the outside of the waterproof mortar, and constructing a heat insulation layer on the waterproof coating; constructing a decoration layer of the outer wall surface on the heat insulation layer, and sealing a chamfer between the outer door or outer window main frame and the decoration layer of the outer wall surface by waterproof and weather-resistant sealant. The anti-leakage construction method has the advantages that by adopting common construction materials and universal tools, the anti-leakage effect of the outer door and window edge of the outer heat insulation wall is improved; the problem of easiness in aging and cracking of weather-resistant rubber between the outer door and window frame and the building wall is solved, the common problem of leakage of the outer door and window edge of the outer heat insulation wall is solved, and the subsequent maintenance cost caused by leakage is reduced.

Description

technical field [0001] The invention relates to the construction field of building exterior walls, in particular to an anti-leakage construction method for exterior doors and window edges of above-ground exterior thermal insulation walls. Background technique [0002] The anti-leakage of the external door and window edge of the above-ground external thermal insulation wall in the prior art is to seal the gap between the outer (door) window frame and the outer wall surface decoration layer with waterproof and weather-resistant sealant to achieve the anti-leakage effect. Therefore, when the waterproof and weather-resistant sealant ages, it is easy to leak at the door and window, which eventually leads to repairs and increases the final construction cost. Contents of the invention [0003] The purpose of the present invention is to provide an anti-leakage construction method capable of avoiding the leakage phenomenon caused by the aging of the rubber strips on the outer door ...
