Description

Technical Field

[0001] The utility model relates to the technical field of building roofs, in particular to a metal roof thermal insulation broken bridge node. Background Art

[0002] Metal roof refers to a roofing form that uses metal sheets as roofing materials and combines the structural layer and the waterproof layer into one. There are many types of metal sheets, including galvanized sheets, galvanized sheets, aluminum alloy sheets, aluminum-magnesium alloy sheets, titanium alloy sheets, copper sheets, stainless steel sheets, etc. The surface of the sheet can be painted, mainly PE / PE, SMP / PE, HDP\PE, PVDF\PE, and these four types of paint treatments can extend the service life of the sheet.

[0003] The existing Chinese utility model patent (application number 201920420473.5) mentions a metal roof insulation thermal insulation node, including a roof panel, a steel beam and an insulation layer arranged between the roof panel and the steel beam. The node also includes a raised layer for raising the distance between the insulation layer and the steel beam. The raised layer is located between the insulation layer and the steel beam. It solves the problem of compression of the insulation layer and isolation of thermal bridges by raising the insulation layer and using wood as an intermediate force transmission component. However, raising the insulation layer increases the thickness of the roof, and the increased occupied space will also lead to an increase in the obstructed area, thereby increasing the resistance range from itself, which does not meet the setting of wind resistance and resistance reduction. In addition, the use of wood will also corrode for a long time, and the corrosion will accelerate the damage of the roof, which is not conducive to promotion and use. Utility Model Content
