Problems solved by technology

The existing construction method can achieve a good waterproof effect on a flat surface, but in some narrow spaces such as corners, the operating space is narrow and the construction is difficult. If waterproof treatment is not carried out, there will be hidden dangers of water seepage during long-term use

Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the present invention is not limited to the following embodiments.

[0034] A method for waterproofing membrane construction, comprising the following steps:

[0035] 1) The base layer 3 is cleaned up, the base surface is treated flat, and the yin and yang corners are made into a circular arc or 135° angle; the surface of the base layer 3 is flat, smooth, and free of looseness. flatten;

[0036] 2) The surface of the base layer 3 is dry, and the moisture content is not more than 9%. Cover the surface of the base layer 3 completely with the coiled material 2 and let it stand for more than 3 hours. Dew phenomenon, that is, the moisture content of the base layer 3 is considered to be less than 9%;

[0037] 3) Brush the base treatment agent 4: use a brush to paint the cold base oil on the surface of the base 3, use ...

Abstract

The invention relates to a waterproof coil construction method. A base layer is cleaned, a base surface is flattened, and inside and outside corners are arranged in a circular arc shape or are 135-degree bevels; the base layer surface is flat, smooth and free of looseness and is smoothened and calendered, and residual mortar blocks or protrusions are flattened through a shovel blade; and the baselayer surface is dry, the moisture content is not higher than 9%, a coil completely covers the base layer surface, still standing is conducted for 3 hours or longer, if the surface of a covered area is free of watermarks, the moisture condensation phenomenon of the side, attached to the base layer, of the coil does not occur, and it shows that the moisture content of the base layer is lower than 9%. The method has the advantages that water leakage hidden danger caused by construction is avoided, the waterproof effect is obvious when construction is carried out according to the method in narrowspaces such as the inside and outside corners and bending corners, leakage is avoided, and the construction cost is low.

Description

technical field [0001] The invention relates to a building waterproof construction method, in particular to a waterproof roll material construction method. Background technique [0002] SBS modified asphalt waterproof membrane is made of SBS modified asphalt as the main material. It is a new type of waterproof membrane that has been highly praised by the society in recent years. cracking, fatigue resistance, aging resistance, strong toughness, good tear strength and puncture resistance, long service life, and excellent waterproof performance. Its construction adopts the hot-melt construction method, and the coiled materials are hot-melted and overlapped, and fused together to form a waterproof layer to achieve waterproof effect. The existing construction method can achieve a good waterproof effect on a flat surface, but in some narrow spaces such as corners, the operating space is narrow and the construction is difficult. If waterproof treatment is not carried out, there wi...
