With the development of modern architecture, metal roofing system has become more and more important in architecture due to its excellent characteristics. Metal roofing panel also has a variety of materials, according to the material properties and price considerations, including aluminum magnesium manganese plate metal roofing system, which has been widely applied in all the country's large public buildings, such as airport terminals, stations, convention and exhibition center, stadiums, public entertainment facilities, shopping center and commercial and civilian residential aluminum magnesium manganese plate was used for the metal roofing system.
The structure of the metal roofing system of aluminum magnesium manganese plate mainly consists of three layers: aluminum magnesium manganese roof plate, insulation layer and metal bottom plate. According to the design requirements, the system can be divided into 6 layers:
The first layer, the 0.9 mmYX65-450 aluminum magnesium manganese plate do panel, panel is one of the direct contact with the atmosphere and rain layer, is essential to the surface of the waterproof design, processing, vertical height, while the choice of direction, the structure of the special node processing, have decided to waterproof the final result.
The second layer insulation layer, generally USES the centrifugal glass fiber sound-absorbing cotton, main insulation and noise reduction effect (such as noise) after the heavy rain, hail impact surface, the top aluminum foil has the good auxiliary waterproof function.
Third floor moistureproof aluminum foil layer, generally USES pure polyethylene film and 0.5 mm to enhance pure polyethylene plate, moistureproof layer can limit internal water vapor into the building, the roof to the emergence of the maximum to avoid the condensing phenomenon.
The fourth layer of sound insulation is usually made of centrifugal glass fiber absorbent cotton.
The fifth layer structure layer, generally use the compression type steel plate or the lining purlin and the steel purlin strip, the structure support, find the slope function.
The sixth layer decorates the layer, generally USES the color steel pressure type bottom plate, the support is absorbent cotton and the insulation cotton, at the same time decorates the function.
Aluminium magnesium, manganese plate of metal roofing systems have protection against water, wind and fire, and the service life of up to 50 years of high-quality performance, such as the quality of the need for installation to achieve more professional, and in the construction of the project details, pay attention to some aspects when in this way can make aluminum magnesium manganese full play to the functions of roofing system, should pay attention to the following points in the construction of:
1, aluminum, magnesium, manganese plate bracket installation: aluminum magnesium manganese plate brackets fixed on purline and purlin vertical, stents and should also ensure that a balance between, otherwise locked stitcher bite side whipstitch will damage the panel, or when used in the future, lead to leakage, blown away, heat bilges cold shrink and cause panel worn. In addition, in the fixed support, the use of a better stainless steel nail, it can prevent the generation of electrochemical reaction, the use of years will not rust loose and affect the quality of the panel.
2, roofing construction details: vertical side whipstitch roofing system requirements should be continuous, smooth, overlock cannot appear distortion and rupture, overlock process make the lap side together, the day in place of panel must complete the overlock, side whipstitch at brace at the same time to consolidate. The metal roofing is waterproof, and the details of the roof, such as the gutter, the pipe in the roof, the cable, etc., should be designed before the roof construction, so as to ensure the appearance and watertight.
3, aluminum, magnesium, manganese panel processing: aluminum magnesium manganese panel directly exposed to the air, the materials into consideration factors such as the wind resistance, mechanical strength, anticorrosion, panel has a strict process, involving long plate under the condition of the construction site processing, take into account the performance of processing equipment, so that under no circumstances can also easily create beautiful streamlined board type. In addition, each node before construction of the system panel design should fully consider the construction actual situation, including between panel and panel side whipstitch occlusion, horizontal vertical lap, lap, roof arc Angle, panels, panel and the transition between the parapet, so as to ensure the construction after the roof system decorative surface has both a good waterproof thermal insulation performance, at the same time as the appearance of the smooth level off.
4. Pretreatment before construction: inspect the metal roof carefully before construction, and make sure that the metal roof is firm, clean and free of frozen objects. If these conditions occur, the construction should be done first. Replace damaged firmware and add firmware at the appropriate location; Remove frost, dust and other loot.
