Bathroom moisture-proof construction method

Abstract

The invention relates to the field of bathroom damp-proof, and provides a damp-proof construction method for a bathroom aiming at the problem that moisture easily permeates into a concrete base layerthrough gaps between adjacent tiles. According to the technical scheme, the method comprises the following steps that S1, cement mortar is coated on the surface of the concrete base layer to form a cement mortar layer; S2, after the cement mortar layer is initially coagulated, the tiles are laid on the surface of the cement mortar layer; and S3, the gaps between the adjacent tiles are filled; andthe cement mortar comprises the following components of, in parts by mass, 100 parts of Portland cement, 350-400 parts of fine aggregate, 100-120 parts of nanofiller, 35-40 parts of a polyurethane adhesive, 3-5 parts of a silane coupling agent, and 90-110 parts of water. The nanofiller is added into the cement mortar, so that the cement mortar layer has good anti-permeability and water-proof effects, the moisture permeates to the concrete base layer with difficulty, the situation that the concrete base layer of the bathroom leaks to influence a lower layer building is reduced, the bathroom iseasier to air dry at the same time, and a better damp-proof effect is achieved.

Description

technical field [0001] The invention relates to the moisture-proof field of toilets, in particular to a moisture-proof construction method for toilets. Background technique [0002] The bathroom is a space for occupants to defecate, bathe, wash and other activities. Due to its special purpose, there is always a lot of water on the floor of the bathroom. Generally, the bathroom structure includes a concrete base structure and tiles laid on the concrete base structure. , The concrete foundation will be coated with a waterproof coating for waterproofing. The coverage of the tiles can effectively protect the waterproof coating and reduce abrasion, thereby preventing moisture from seeping down. [0003] However, since it is impossible to use a whole piece of tiles to completely cover the concrete base structure, it is usually necessary to splice several tiles, stick the tiles to the concrete base structure and fill the gaps between the tiles through adhesives, but after a long pe...

Problems solved by technology

[0003] However, since it is impossible to use a whole piece of tiles to completely cover the concrete base structure, it is usually necessary to splice several tiles, stick the tiles to the concrete base structure and fill the gaps between the tiles through adhesives, but after a long period of use , the adhesive between the tiles is flush with the tiles, and it is prone to wear during cleaning and use. Once the adhesive in the gap between adjacent tiles is worn away, the waterproof coating will be exposed , in the process of continuous use, it is easy to wear and tear the waterproof coating, so that moisture can easily penetrate into the concrete base through the gap between adjacent tiles, and then seep to the top of the substructure, causing the top of the substructure to be wet, which is easy to cause The bulging and peeling of the putty layer on the ceiling of the lower building will seriously affect the quality of the lower building's ceiling, so there is still room for improvement
