Abstract

The invention provides a double-layer roof system capable of improving waterproof performance. The double-layer roof system comprises a plurality of purlins, a plurality of roof bottom plates which are mounted on the purlins and sequentially connected, and a plurality of roof top plates which are located above the roof bottom plates and sequentially connected. Each roof bottom plate comprises a bottom flat plate, a first connecting part and a second connecting part, wherein the first connecting part and the second connecting part are located at the two ends of the bottom flat plate correspondingly. Every two adjacent roof bottom plates are fixed through overlapping of an adjacent first bending part and second bending part. A U-shaped keel is arranged between every two adjacent roof bottomplates and mounted onto the corresponding purlin, and the U-shaped keels and the corresponding first connecting parts as well as the U-shaped keels and the corresponding second connecting parts are fixed through fasteners from the side faces. The connecting positions of the roof bottom plates has the waterproof ability, and the roof bottom plates are combined with the roof top plates with the waterproof performance, so that the function of the second waterproof defense line is achieved, and the leakage condition of the roof system is avoided to the largest degree.

Description

technical field [0001] The invention relates to the technical field of building roofing, in particular to a double-layer roofing system with improved waterproof performance. Background technique [0002] Due to its light weight, high strength, beautiful appearance, and convenient construction, the profiled metal roof system is widely used in large-scale projects such as airports, stadiums, exhibition centers, industrial plants, warehouses, railway station canopies, and railway station roofs. [0003] At present, metal roofs mainly have two forms: single-layer metal roof panels and double-layer metal roof panels. For the lap-joint roof panel, the overlap between the roof panel and the roof panel is where its weak point is located. This type of lap joint is to fix the lap joint of the roof panel with the roof keel or bracket by self-tapping screws, and the gap between the screw and the panel Seal and waterproof by rubber gasket and weather-resistant sealant. Leakage is likel...
