Anti-typhoon and anti-leakage metal roof system

Abstract

The invention discloses an anti-typhoon and anti-leakage metal roof system. The metal roof system sequentially comprises a main steel structure, main roof purline, secondary roof purline, pressed steel bottom plates and purline laid on the pressed steel bottom plates from top to bottom. A plurality of fixed seats are fixed to the purline at intervals, concave roof plates which are engaged with thefixed seats are arranged between the fixed seats, and multiple layers of sound-insulation and vapor-proof thermal insulation materials are laid on the pressed steel bottom plates. The fixed seats include fixed supporting seats and panel engaging plates, wherein the purline is fixedly connected with the lower ends of the fixed supporting seats; the panel engaging plates are fixedly connected withthe fixed supporting seats, and small angles are formed between the panel engaging plates and the fixed supporting seats in the length direction of the roof plates so that the panel engaging plates and the fixed supporting seats can rotate relatively; and panel engaging parts are formed in the upper parts of the panel engaging plates, and the panel engaging parts and both side edges of the roof plates form engaging connection. The anti-typhoon and anti-leakage metal roof system solves the problems that a traditional metal roof system with vertical lockrands has low wind resistance, and is prone to leaking and prone to producing expansion deformation damage, and the safety of upper supporting facilities is affected.

Description

technical field [0001] The invention relates to the technical field of building roof systems, in particular to a typhoon-resistant and leak-proof metal roof system. Background technique [0002] At present, the main structure of large-scale long-span public buildings is mostly constructed in the form of steel structure. In the maintenance structure system, the roof generally adopts a complex multi-layer metal roof system. [0003] The metal roof system has been used in my country for nearly 30 years. As the building shape becomes more and more complex and the height is higher and higher, the metal roof faces more and more difficulties. Not only must the appearance be beautiful, but also thermal insulation must be satisfied. , sound-absorbing and sound-insulating, steam-proof, moisture-proof, anti-corrosion and other functional requirements, but the wind resistance and water resistance related to safety are particularly critical and important. [0004] While a large number of...

AI Technical Summary

Problems solved by technology

[0010] The purpose of the present invention is to solve the problems of the traditional standing seam metal roof system, such as weak wind resistance, easy leakage, easy to produce expansion and deformation damage, and affect the safety of upper supporting facilities, and provide a new type of typhoon-resistant and anti-leakage metal roof system
