First of all, it is necessary to see whether there is a parapet on the aluminum magnesium manganese roof. The aluminum alloy plate end of the cornice where there is a parapet has relatively small wind suction, so it has strong wind resistance. If the
aluminum magnesium manganese plate cornice is overhanging, it is just affected by the wind, and it is easy to be lifted by the wind. Therefore, it is necessary to install the internal plug of the roof panel at the cornice, but
Some irresponsible aluminum magnesium manganese roof construction teams did not install high vertical edge plate sealing plug at cornice, which led to a linear decline in wind resistance of metal roof;
Second point: the folding parts on both sides of the aluminum magnesium manganese ridge cover plate should not only be the wave crest of laying the aluminum magnesium manganese plate, but should be cut,
The side cover is covered with the trough of Al Mg Mn alloy plate, and polyethylene foam outer plugs are installed inside.
The joint between the ridge tile and the aluminum magnesium manganese plate is filled with the post weathering sealant to form a seamless whole,
This is not only waterproof and leakproof, but also reduces the impact of wind on the metal roof system,
The third point: the fixed seats at cornice and roof ridge need to use 4 self attack factors in the urban area with strong wind all the year round
Aluminum alloy fixed base, to ensure the fastening axial force, increase the wind resistance of the roof.
