Description

A purlin-free single roll high waterproof roof panel system

technical field

The invention relates to a metal roof panel system, in particular to a purlin-free single roll high waterproof roof panel system, which belongs to the technical field of industrial building design and construction.

Background technique

The roof of the building includes metal roof, concrete roof, tile roof, etc., but the metal roof is limited by the forming rigidity and bearing capacity of the profiled steel plate, so basically the purlins with small spacing are used on the main structure (the spacing is about 1.2- 1.5m), and then lay metal roof panels, thermal insulation cotton, waterproof membrane and other roofing systems on the purlins in sequence.

However, this traditional method has a great impact on construction, especially in industrial plants, where a large number of tie rods, tie bars and supports are installed between the rigid frames to form a stable system, and then a large number of purlins are installed on the roof and walls. The workload of procurement, processing and on-site installation is huge, and the cost of construction is relatively high. Moreover, there are certain requirements on the delivery and installation sequence of the components, which reduces the construction efficiency. At the same time, the traditional metal roof system is composed of multi-layer structures and needs to be installed through at least 8 processes. During the installation process, the quality requirements of construction workers are very high. After forming, it is not easy to inspect, and there are hidden dangers such as water leakage and lack of heat preservation. More importantly, if the metal roof panel adopts common composite panels on the market, one side of the longitudinal lap joint will be in a cantilevered state during laying, and the rigidity of the longitudinal lap joints between two adjacent composite panels will be inconsistent, resulting in joints. The joints often show poor deformation or uncoordinated deformation after being stressed, and there is a hidden danger of water leakage.

Based on this, the present invention is proposed.
