During installation, strengthen site management and strictly control each process.
Purlins must be installed by pulling through the line and leveling, otherwise the color steel plate will bear the load, some purlins are virtual, and the fixing screws will be due to the height of the purlins
Pull and fold the color board with different degrees.
The fixing screw shall be installed with proper force and shall not be biased, so that the waterproof washer will lose its waterproof function. 10C is adopted for the treatment of roof screws and fastenersm × 10cm wide waterproof layer.
is to more effectively prevent rainwater from entering the roof. When the roof outer plate is at the ridge, use the edge closing tool to turn the color plate at the steel plate terminal towards the roof
Fold up to ensure that the water blown in by the wind under the flashing or cover plate will not flow into the building. At the lower end of the eaves, the end of the steel plate shall be bent slightly downward(lip shape), a downward folded edge
will be formed at the end of the steel plate, so as to ensure that the rainwater will be discharged along the end of the steel plate and will not be caused by capillary or wind
The force returns to the lower edge of the roof slab. The contour plate
has a corresponding molding foam sealing strip, which is embedded between the eaves supporting surface and the lower side of the roof panel.
(used as eaves seal). Insert the molding strip between the lower part of the flashing plate and the top
surface of the roof panel along the lower part of the flashing plate and the cover plate, and use double-sided adhesive tape
Proper fixing, so as to play a similar sealing role.
For a single-layer color plate house, in order to reduce the heat radiated by the sun into the building, when installing the roof panel, heat insulation can be installed in the roof system
Layer. Before installing the roof steel plate, lay double-sided reflective foil film on the purlin or strip. This method can also be used as steam isolation to reduce
Less condensation. In order to reduce condensation under the roof steel plate, a moisture-proof plate must be set under the steel plate to prevent moisture between the lower surface of the steel plate and the air
Contact. If condensation occurs in buildings, it is difficult and costly to eliminate its adverse effects. Therefore, in the design and construction
Take precautions. In order to avoid water condensation on the roof, wet air must be prevented from contacting under the steel plate. Used in reflective foil layer and roof
The method of placing heat insulation cotton between steel plates will further avoid the invasion of moisture. When thermal insulation cotton layer is used, care must be taken to keep it completely moisture-proof. Especially for
Around the edge of the roof and at the bottom of the steel plate terminal, in the case of a small slope roof, the rainwater may be blown back. If the insulation cotton is suspended on the bottom support
Above the surface, it may be in contact with the water in the gutter. In this case, the heat insulation cotton will absorb water and retain the moisture for a long time during humid climate
In the insulation cotton, this will damage the roof panel coating due to contact with wet insulation cotton.
