Building external wall waterproof and anticracking construction method

Abstract

The present invention discloses waterproof anti-cracking building outer wall constructing process and belongs to the field of building waterproofing technology. The constructing process includes the following steps: 1. painting elastic sealing glue to the outside of the frame beam and the interfaces between beam and column and wall before the outer wall is plastered; 2. painting waterproof polymer mortar after the sealing glue is cured, and adhering polyethylene-polypropylene film; and 3. adhering the edge of the film with waterproof polymer mortar onto the wall. The present invention is suitable for different kinds of building outer wall.

Description

technical field [0001] The invention relates to a construction method for waterproofing and anti-cracking of building exterior walls, which belongs to the technical field of building waterproofing. Background technique [0002] The existing waterproof and anti-crack technology for building exterior walls cannot achieve a satisfactory waterproof and anti-crack effect, and building leakage is common. Building leakage accounts for a significant percentage of homeowner complaints in the real estate industry today. In fact, the quality problems of building waterproofing are often difficult to find during acceptance, decoration and occupancy, but after one or two years, the joints of different materials are prone to cracking and leakage due to uncoordinated deformation caused by thermal expansion and contraction. Therefore, due to the poor waterproof quality of many houses, after delivery for use, either the bathroom leaks, or the outer wall or roof leaks. [0003] In the waterp...

Problems solved by technology

[0003] In the waterproof construction of many parts of the building, the exterior wall has always been a major difficulty in waterproof construction, and has become a major research topic in the industry. Even regular waterproof companies still cannot overcome the exterior wall after construction with various formal materials. cracked wall problem

The reason is that the initial setting and contraction of the mortar on the exterior wall of the building, the internal cracks will expand and contract under the action of sunlight, and cracks will inevitably occur, which directly leads to the leakage of the building
