Application of wind-resistant fixture for Al-Mg-Mn aluminum plate

According to many years of construction experience, the wind damage to the aluminum magnesium manganese aluminum roof system can be attributed to the following reasons:

1. The design scheme and local air volume control are poor, and the technology of strengthening wind protection design is immature;

2. In terms of material selection of system accessories, in order to save engineering cost, choose accessories with poor quality;

3. The construction personnel are not qualified enough, and the details of the building are not strictly controlled, and the work is cut corners, resulting in loopholes in details; The design or construction treatment of the roof, gable and other roof panel joints is not in place, which leads to slight damage in subsequent use, thus affecting the whole roof panel.

In order to prevent the Al-Mg-Mn-Al plate from being overturned by strong wind, a wind-resistant fixture can be installed on the installed roof panel. The fixture, also known as secondary strengthening wind-resistant fixture and adapter, consists of two aluminum alloys and two sets of stainless steel screws. Aluminum alloy wind clamp is an accessory in aluminum magnesium manganese plate roofing system, which is made of pure aluminum alloy profiles. Aluminum alloy wind clamp is also called secondary top clamp, aluminum magnesium manganese plate clamp, vertical locking clamp, aluminum alloy fixed wind clamp, etc.

Aluminum alloy wind clamp can be divided into point clamp (grooved base), plane clamp, semi-plane clamp and new plane clamp. Aluminum alloy wind clamp has two main functions:

1. In order to prevent the Al-Mg-Mn roof panel from being lifted, the connection of Al-Mg-Mn roof panel is fixed on the aluminum alloy bracket by vertical edge sewing machine, and there are no screws on the surface, so it is easy to relax due to thermal expansion and cold contraction caused by climate change. It is easy to be lifted when encountering strong winds. The installation of aluminum alloy windproof clips can prevent this situation, thus making the whole roof have a longer service life.

2. Strengthen the practicability of the roof system. Although the aluminum-magnesium-manganese-aluminum roof has a good aesthetic function, it is not as practical as traditional buildings because solar energy and other equipment can be installed on the roofs of traditional buildings. Using aluminum alloy windproof fixture can not only improve this shortcoming of aluminum-magnesium-manganese roof, but also install aluminum veneer on aluminum alloy fixture to make the whole house more beautiful.

Benefits of using aluminum magnesium manganese aluminum plate

Aluminum-magnesium-manganese aluminum roof panels have many advantages, such as corrosion resistance, beauty, light weight, easy to manufacture and shape, and so on. They are used in airport terminals, aircraft maintenance garages, stations and large transportation hubs, conference and exhibition centers, stadiums, exhibition halls, large public entertainment facilities, public service buildings, large shopping centers, commercial facilities, civil residences and other buildings. More and more construction units and individuals choose to use aluminum-magnesium-manganese roof panels.

1, the base material is anticorrosive and has high durability;

The brand A3004 Al-Mn-Mg alloy is adopted, which has high corrosion resistance. Surface damage caused by transportation or construction does not affect its anticorrosion ability;

2, reliable waterproof performance:

The fixing method adopts concealed buckle and mechanical edge locking, and no screw passes through the roof to avoid the hidden danger of water leakage; Make maximum use of the cross-sectional area of the panel for drainage with high drainage efficiency; The transverse lap edge is hinged by the edge hinge machine, which has good sealing performance and anti-capillary action measures; Adopt sliding fixed seat to avoid panel damage caused by temperature deformation; Adopt mobile profiling equipment to break through the limitation of transportation conditions on plate length and reduce longitudinal overlap; Aluminum-magnesium-manganese-aluminum alloy roof panels and flashing are allowed to be welded, which improves the waterproof problem of roof openings.

3. Good modeling adaptability:

The Al-Mn-Mg alloy material used has considerable strength and good flexibility, which is very suitable for roofs with complex shapes.

4. Beautiful materials and convenient use:

Fluorocarbon spraying (PVDF) paint on the surface to meet the color requirements of design and use; Generally, there is no need for washing and maintenance during use.

5. On-site pressing production mode:

Al-Mg-Mn aluminum plate has high flexibility, which is convenient to adjust production parameters according to the construction site conditions, and is conducive to shortening production cycle and realizing product quality.
