Composite roofing steel bearing metal plate system with secondary waterproof function and construction method

Abstract

The invention belongs to the technical field of building engineering, and relates to a composite roofing steel bearing metal plate system with a secondary waterproof function and a construction method. The composite roofing steel bearing metal plate system is a finished plate composed of multiple layers of composite structures and comprises a waterproof layer, a secondary waterproof metal plate supporting seat, a metal leveling layer, a filling layer, a metal frame, a filling leveling layer and a metal flat-sealed edge plate which are composited one by one to be machined into a finished product, the pre-modular degree reaches 90%, the construction period is greatly shortened, and the assembly and laying efficiency is improved; meanwhile, material pollution is further reduced; the compositeroofing steel bearing metal plate system structure with the secondary waterproof function is a closed-opening type, and the pollution degree is reduced to the minimum; the application range of the finished plate is enlarged by selecting a heat insulation material and a fireproof material; and the whole structure strength, safety, the fireproof grade and waterproof performance of the metal plate are further improved by adopting matching of the secondary waterproof metal plate supporting seat and the waterproof layer.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and relates to a composite roof steel bearing metal plate system with secondary waterproofing and a construction method; it is suitable for flat roofs, sloping roofs and a small number of heterogeneous roofs in public buildings and civil buildings. Background technique [0002] As the country vigorously promotes green prefabricated buildings, in the design and construction of steel structure roofs, the steel structure roofs in the prior art lack a prefabricated plate production and installation system, the degree of pre-modularization is low, and the roof construction period is long. Pollution and other technical problems. Therefore, there is an urgent need to develop a steel structure roof structure that can realize the integral splicing of the roof and has a high degree of pre-modularization to solve the above technical problems. Contents of the invention [0003] Purpose of...
