A method for integrating a pvc waterproofing membrane to lay a surface and an inner corner

Abstract

The invention discloses a method for integrally laying vertical surfaces and internal corners by using PVC waterproof coiled materials. The waterproof coiled materials further comprise first internalcorner waterproof coiled materials for laying of the internal corners, and the first internal corner waterproof coiled materials comprise third edges and fourth edges, the third edges is in overlap joint with planar waterproof coiled materials which have been laid, and the fourth edges are in overlap joint with vertical surface waterproof coiled materials which have been laid. The method comprisesthe following steps: folding the first internal corner waterproof coiled materials so that the appearances of the first internal corner waterproof coiled materials are consistent to the appearances of the internal corners; beginning to lay the first internal corner waterproof coiled materials at positions which are distant from the edges of the internal corners by 30-50 cm, enabling the third edges of the first internal corner waterproof coiled materials to be in overlap joint to the upper portions of the edges of the planar waterproof coiled materials to form third overlap joint sides, and enabling the fourth edges of the first internal corner waterproof coiled materials to be in overlap joint to the upper portions of the edges of the vertical surface waterproof coiled materials to formfourth overlap joint sides; and welding the waterproof coiled materials together by a welding gun.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for integrally laying facades and interior corners with PVC waterproof coiled materials. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis The leak-free connection with the building is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. Therefore, waterproof membranes are constantly being applied to various buildings. For example, patent CN201510614921.1 discloses a basement floor and waterproof coiled material integrated construction method and waterproof structure. The waterproof structure is a pre-applied self-adhesive film waterproof coiled material laid on the horizontal surface of...

AI Technical Summary

Problems solved by technology

This method has better waterproof performance, but in the end it needs to be poured with cement, which will increase the cost and is not conducive to large-scale use

Moreover, most of the existing laying methods for the inner corner are to trim the waterproof coiled material laid at the inner corner, and then fold it into the shape of the inner corner. Due to the way of trimming, the waterproof area of ​​the waterproof coiled material is reduced, and rainwater is easy to pass through the trimmed place. Then it penetrates into the ground, which is not conducive to waterproofing
