Description

Technical Field

[0001] The utility model relates to the technical field of metal roof waterproofing, in particular to a metal roof waterproofing connection device. Background Art

[0002] At present, with the demand of architectural design, metal roof panels are widely used. The ridge connection formed by the metal roof connection has always been a place prone to leakage accidents. Especially for the special-shaped connection, leakage has become the biggest hidden danger, and many leakage accidents have occurred. At present, the fixing methods of the upper plate of the metal roof system mainly include overlap, bite, vertical lock edge and other forms. For the overlap type roof panel, the overlap between the plates is its weak point. This overlap form is to fix the overlap of the plate with the roof keel or bracket by self-tapping screws, and the screws and the plate are sealed and waterproofed by rubber gaskets and weather-resistant sealants. The overlap of the two layers of plates and the nail holes of the self-tapping screws are prone to leakage. Leakage will cause rust of the self-tapping screws and the steel at the position of the self-tapping screw holes, and the fastening effect of the self-tapping screws will be greatly reduced or even lose its connection function. Therefore, it is necessary to design a metal roof waterproof connection device to overcome the problem that the existing metal roof panel fastening connector is prone to leakage and loses its connection function.
