Metal roof secondary waterproof structure and construction method

Abstract

The invention discloses a metal roof secondary waterproof structure and a construction method. The metal roof secondary waterproof structure comprises a roof layer (1), a cavity layer (2), a secondary waterproof layer (3), a gutter (4), a main steel structure (5) and a stand column purlin hanger (6). The cavity layer (2) is located between the roof layer (1) and the secondary waterproof layer (3). The stand column purlin hanger (6) is supported on the main steel structure (5) for supporting the roof layer (1) and the secondary waterproof layer (3). The waterproof structure can prevent the phenomenon that the integrity of a coiled material is damaged by an aluminum alloy support needed by installing a metal panel, and further improves the waterproof performance of the metal roof, and the cavity layer, a heat preservation layer, a sound absorption layer and a steam isolation layer are arranged in the roof structure, so that the waterproof structure has the good sound-insulating, heat-preserving and damp-proof effects.

Description

technical field [0001] The invention relates to waterproofing of building structures, in particular to a multiple waterproofing structure and a construction method of a metal roof. Background technique [0002] The iconic steel structure buildings such as stations, airports, stadiums, and exhibition centers that require first-level waterproofing mostly use metal panels and PVC waterproof membranes for secondary fortification. In the traditional laying method, the T-shaped aluminum alloy support required to install the metal panel will destroy the integrity of the PVC waterproof membrane. Once the metal panel leaks, the accumulated water seeps into the room along the self-tapping nail holes, and PVC does not play the role of secondary waterproofing, which causes a major safety hazard while costing money. Therefore, without increasing the project cost, it is necessary to seek a The structure that meets the first-level waterproof requirements and can ensure that the metal pane...

Once the metal panel leaks, the accumulated water seeps into the room along the self-tapping nail holes, and PVC does not play the role of secondary waterproofing, which causes a major safety hazard while costing money. Therefore, without increasing the project cost, it is necessary to seek a To meet the first-level waterproof requirements and ensure that the metal panel leaks, the PVC waterproof membrane can really play the role of secondary waterproof structure, which becomes the starting point for the design of metal roof structures
