Metal roof wind-resistant clamping piece, clamp, system and composite roof wind-resistant system

Abstract

The invention discloses a metal roof wind-resistant clamping piece. The metal roof wind-resistant clamping piece comprises a clamping piece body, an anti-disengagement part is arranged in the middle of the clamping piece body, and an anti-deformation part is arranged at the bottom of the clamping piece body. The invention further discloses a metal roof wind-resistant clamp, the wind-resistant clamp comprises two wind-resistant clamping pieces which are oppositely arranged, the two wind-resistant clamping pieces are oppositely arranged, and the anti-deformation parts of the two wind-resistant clamping pieces are located on the opposite sides of the two wind-resistant clamping pieces respectively; an anti-disengagement area matched with a lock catch is formed between the anti-disengagement parts of the two wind-resistant clamping pieces, the two wind-resistant clamping pieces are connected and fixed through bolts, and the bolts are located above the anti-disengagement area. The inventionfurther discloses a metal roof wind-resistant system and a composite roof system. The metal roof wind-resistant clamping piece, clamp and system disclosed by the invention have the advantages that the tripping problem and the fulcrum lateral instability problem caused by deformation of the metal roof can be effectively prevented; the temperature stress (thermal expansion and cold contraction) inthe length direction of the plate surface can be effectively released; and the stress conduction of the fulcrum can be effectively increased when the roof system is composited, and the fulcrum lateralinstability is prevented.

Description

technical field [0001] The invention belongs to the technical field of metal roof panel node connection structures, in particular to a metal roof wind-resistant clip, a fixture, a system and a composite roof wind-resistant system. Background technique [0002] Metal roof refers to the roof form that uses metal sheet as the roof material and combines the structural layer and waterproof layer into one. There are many types of metal sheets, including galvanized sheet, galvanized sheet, aluminum alloy sheet, aluminum-magnesium alloy sheet, titanium alloy sheet, copper sheet, stainless steel sheet, etc. The surface of the sheet can be treated with baking paint, mainly including PE / PE, SMP / PE, HDP\PE, PVDF\PE are four kinds of baking varnish treatments. Baking varnish can enhance the service life of the board, which are 5-8 years, 10-15 years, 15-20 years, and 20-25 years or more. The metal roof generally includes a metal roof panel 1, and the two sides of the metal roof panel 1...

AI Technical Summary

Problems solved by technology

In addition, the wind-resistant clamp for the metal roof is fastened by fastening bolts, which easily leads to the deformation of the metal roof in the length direction, and there are problems that the metal roof cannot expand with heat and contract with cold, and the temperature stress cannot be released.
