Abstract

The invention provides a bilayer roof plate system with waterproofness improved. The bilayer roof plate system comprises a main purline, auxiliary purlines, roof plates and a roof baseplate, each two adjacent roof plates are fixedly connected through a locking device which comprises a support keel and a buckle cover, the upper end of each roof plate is clamped between the corresponding support keel and the corresponding buckle cover, each locking device is mounted on the corresponding auxiliary purline through a conversion member, the edge of each buckle cover is provided with a flange extending toward the outer side in an obliquely downward manner, each support keel is positioned in a vertical projection of the corresponding buckle cover, a threaded hole is formed in each buckle cover, each roof plate is fixed and compressed between the corresponding support keel and the corresponding buckle cover through a bolt, a cover cap is arranged above each buckle cap, and each bolt covers in the corresponding cover cap. A fixing mode through the buckle covers is adopted, and each buckle cover covers the corresponding bolt and a joint of the corresponding roof plate and the corresponding support keel, so that no screw of a roof is exposed, the whole roof is attractive, potential trouble in water leaking caused by existing screws is eliminated completely, and waterproofness of the bilayer roof plate system is improved.

Description

technical field [0001] The invention relates to the technical field of light steel roofs of building structures, in particular to a double-layer roof panel system for improving 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. However, due to insufficient wind-resistance ability, the phenomenon of metal roof being torn off by wind frequently occurs, and the phenomenon of metal roof water seepage also frequently occurs. [0003] At present, the fixing methods of the upper slab of the double-layer roof slab system mainly include lap joint type, snap-in type, standing seam and other forms. [0004] For the lap-joint roof panel, the overlap between the roof panel and the roof panel is w...
