Description

Technical Field

[0001] The utility model relates to a wind-resistant double-layer metal roof structure, belonging to the technical field of building construction. Background Art

[0002] With the development of the construction industry, metal roofs have been widely used due to their durability and aesthetics. However, in areas with strong winds, metal roofs often face the problem of wind-uplift resistance, which not only affects the stability of the roof, but may also cause structural damage and increased maintenance costs. Existing metal roofing systems have limitations in wind resistance. Many systems have a single fixing method and fail to fully consider the impact of wind loads, causing the upper panels to easily deform or fall off under strong wind conditions. At the same time, functional designs such as waterproofing, thermal insulation, and sound absorption are often relatively independent and lack integrity, affecting the service life and comfort of the roof. Therefore, there is an urgent need for a new metal roof system structure that can effectively improve wind-uplift resistance while taking into account functions such as dustproofing, moisture-proofing, thermal insulation, and sound absorption to meet the multiple needs of modern buildings. Utility Model Content

[0006] Furthermore, the decorative layer includes an aluminum veneer, and an aluminum alloy keel is connected to the bottom of the aluminum veneer through a stainless steel clamp. The stainless steel clamp is provided with an angle code. The thickness of the stainless steel clamp is 2.0 mm and the material is SUS316; the size of the aluminum alloy keel is 60*60*3 mm, model 6063-T6, fluorocarbon sprayed; the thickness of the aluminum veneer is 3 mm and fluorocarbon sprayed.

[0007] Furthermore, the suspended top layer is a 0.8 mm thick perforated aluminum-zinc corrugated steel plate YX35-190-760, with a hole diameter of not less than 5 mm and an opening rate of 25%.

[0009] Furthermore, the lower panel is a 1 mm thick aluminum-zinc coated corrugated steel plate YX25-210-840, and the moisture-proof layer is a 0.3 mm thick polyethylene vapor barrier film.

[0010] Furthermore, the "J"-shaped keel is a 30*164*70*4mm thick "J"-shaped hot-dip galvanized steel keel, and the "J"-shaped lining purlin is fixed on the "J"-shaped keel with self-tapping screws; the "J"-shaped lining purlin is fixed on the "J"-shaped lining purlin support.
