Single-layer waterproof prepared roofing and construction method thereof

Abstract

The invention discloses a single-layer waterproof prepared roofing and a construction method thereof. The roofing comprises a base layer, a vapor-proof layer, a heat preservation layer and a waterproof layer, wherein the base layer is a concrete roofing board or a steel plate; the vapor-proof layer, the heat preservation layer and the waterproof layer are sequentially arranged on the base layer; the vapor-proof layer is a polyethylene film layer which is laid on the base layer in a border adhibiting way; the heat preservation layer is fixed on the base layer through a fastening gasket and a fastening nail; and the waterproof layer is a single-layer thermoplastic polyolefin waterproof roll layer or a single-layer polyvinyl chloride waterproof roll layer, and is fixed on the base layer in a mechanical fixing way. The roofing is simple in structural hierarchy and high in degree of design freedom; and in addition, the single-layer operation of a wide roll is adopted, so that structural layers and operation levels are reduced, the weight is reduced, the materials are saved, and the construction cost is lowered.

Description

technical field [0001] The invention belongs to the field of roof engineering, and in particular relates to a single-layer waterproof roll roof and a construction method thereof. Background technique [0002] The roof is the enclosure and load-bearing structure that covers the uppermost layer of the house, and one of its most important functions is to "shelter the wind and rain". The roof can be divided into flat roof and sloping roof according to the drainage slope. Generally, the slope of the flat roof is less than 10%, the most commonly used slope is 2~3%, and the slope of the sloping roof is above 10%. Traditionally, Chinese buildings use sloping roofs, including double-sided slopes and four-sided slopes. This kind of roof has a large slope, flexible expansion and contraction, rapid drainage and better waterproof effect. Since the 1960s, in order to reduce the weight of the roof, reduce the cost of the project, and improve the degree of prefabrication of the roof, it ...

AI Technical Summary

Problems solved by technology

[0004] With the development of my country's construction technology in recent years, large-span, light-weight and high-rise buildings are increasing day by day, so that the deformation of the roof structure has changed greatly, and the appearance of roofs such as parking lots, sports fields, and gardens has greatly increased the functions of the roof. Since the 1980s, the problem of house leakage has become a very prominent problem in my country's engineering construction. In order to solve the problem of roof waterproofing, the layers of roof structure have been continuously increased during construction, and more construction resources have been consumed, but the effect has not been very good. Obviously, it does not meet the national building energy conservation requirements
