A method of outsourcing waterproof construction that penetrates metal roof panel components

Abstract

The invention relates to an outsourcing waterproofing construction method for penetrating metal roof panel components. The frame body protrudes from the upper end surface of the substrate, thereby providing a certain support for the second waterproof coiled material through the frame body, which is beneficial to reduce the damage of the second waterproof coiled material. The hollow is beneficial to reduce the tensile stress received by the second waterproof membrane. After laying the first waterproof roll material and the second waterproof roll material, the external waterproofing is carried out by applying a waterproof paint layer, so as to ensure the waterproof effect of the holes through multi-layer waterproofing. The whole structure cooperates with each other, and the waterproof cover plate is connected with the original roof panel to increase the overall rigidity of the waterproof structure, reduce the relative displacement between the flexible waterproof material and the metal roof panel, and protect the flexible waterproof material; at the same time, it is better to use flexible waterproof materials Excellent flexibility, to avoid the waterproof part being damaged by the vibration and displacement caused by the live load.

Description

technical field [0001] The invention relates to the technical field of roof waterproofing, in particular to an outsourcing waterproof construction method that penetrates through metal roof panel components. Background technique [0002] At present, when some gymnasiums are reinforced against wind, the building is often reinforced by adding a "wind-resistant cable structure", that is, a wind-resistant support is installed on the original roof structure, and the wind-resistant support is tightened by steel cables. Form a high-strength mesh roof panel attachment system. The wind-resistant support needs to be connected with the load-bearing structure of the building, so it is often necessary to open holes on the metal roof of the building to realize the connection between the wind-resistant support and the load-bearing structure of the building roof. [0003] Existing metal roof panel components such as the above-mentioned wind-resistant support generally need to be installed o...

AI Technical Summary

Problems solved by technology

Therefore, it is necessary to cut a hole of 250mm by 400mm on the original metal roof panel to install the wind-resistant support. After the wind-resistant support is installed, there will be a large gap between the wind-resistant support and the original metal roof panel. The waterproof membrane is covered and sealed, and the rigidity of the waterproof structure is very small. The live load and wind load of subsequent construction will cause a large displacement between the waterproof material and the metal member, and even cause damage to the waterproof material. Therefore, there is room for improvement
