Crest fixed metal roof structure and construction method thereof

Abstract

The invention discloses a crest fixed metal roof structure and a construction method thereof. The structure comprises roof steel beams, roof main purlines, roof secondary purlines, metal roof slabs, vapor barriers, Z-shaped keels, thermal insulation layers, waterproof and vapor-permeable membranes (8) and roof boards. Cross sections of the metal roof bottom plates comprise alternately arranged bottom plate crest sections and bottom plate trough sections, the metal roof bottom plates and the roof secondary purlines are fixedly connected through first connecting parts penetrating through the metal roof bottom plates and the roof secondary purlines, the first connecting parts corresponding to the positions of the bottom plate crest sections are transversely arranged at intervals, the Z-shapedkeels, the vapor barrier membranes and the roof secondary purlines are fixedly connected through second connecting parts penetrating through the Z-shaped keels, the vapor barrier membranes and the roof secondary purlines, and the second connecting parts corresponding to the positions of the crest sections are transversely arranged at intervals. The crest fixed metal roof structure successfully utilizes the installation manner of the crest fixed metal roof bottom plate and Z-shaped keels to thoroughly solve the problem that nail holes exist in the metal bottom plate troughs, reduces condensatewater to the greatest extent and avoids leakage of the condensate water.

Description

technical field [0001] The invention relates to a metal roof structure, in particular to a wave crest fixed metal roof structure and a construction method thereof. Background technique [0002] The metal roof system has become a common roof system in my country's steel structure roofs. The metal roof bottom plate is fixedly connected to the roof sub-purlins through the nail holes in the bottom plate troughs. However, with the large-scale application of metal roofs, the problem of condensed water in metal roofing systems has gradually been exposed. Here, condensed water often leaks through the nail holes in the troughs of the bottom plate. [0003] The specific problems are as follows: [0004] First, the number of nail holes on the base plate is large, which increases the construction cost; [0005] Second, there are nail holes in the bottom slab of the metal roof. The impermeability and durability of the bottom slab are low, and the nail hole sealant is prone to aging due...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a wave crest-fixed metal roof structure and its construction method, to solve the problem that there are many nail holes in the bottom plate of the metal roof, which increases the construction cost, the construction efficiency is low, the construction period of the metal roof is long, and the bottom plate is resistant Low seepage durability, condensed water seeps into the room through nail holes, causing technical problems for secondary maintenance;
