In order to better waterproof, after the installation of the color coating roll, use special tools to put the color coating roll by the ridge, fold 3CM, about 800.
In the transportation to the roof on the day of the color coated roll can not be fully installed, with the use of knots to make it firmly fixed on the steel truss, the specific implementation can use brown rope or 8# lead wire will be firmly bound, which will avoid any damage to the color coated roll in strong weather.
Roof cover should be constructed as soon as possible after the completion of the roof. If not, the insulation material at the roof should be protected by plastic sheeting to prevent rainy days from affecting the insulation effect.
The construction of ridge cover plate should ensure that the seal between it and the roof and the ridge cover plate is reliable.
When the roof is hoisted to the roof frame for installation, attention should be paid to the orientation of the female rib of the painted roll first according to the installation aspect. If the non-female rib should be adjusted immediately, we must ensure the correct installation position of the first plate to check its verticality to the roof roof groove, ensure that all dimensions are accurate, fix the first bottom plate, and install the subsequent bottom plate with the same technique. Always use the positioning counties to ensure that the ends of the roll are neatly in a straight line.
(1) Vertical transport plate, ensure that the mother rib towards the installation of the beginning of the method, install the first row of fixed bracket and roof attached purlin fixed, adjust its position, to ensure the accurate position of the first roof, fixed the first row of fixed bracket.
(2) Place the first piece of color coating roll on the fixed bracket according to the direction orthogonal to the gutter. First align the middle ribs with the corner of the fixed bracket, then fasten the middle ribs and female ribs onto the fixed bracket with foot ribs or wooden purlins, and check whether they are completely fastened.
(3) Fasten the second row of fixed support to the installed painted roll rib and install it on each support piece.
(4) The female rib of the second piece of color coating roll is fixed with the second row of fixed bracket, and it is also tightened from the middle to both ends. The color coating roll is installed in the same way. The connection should be securely fastened, and the roof should be checked at any time to form a straight line at the gutter, and the verticality of the gutter and other positions is accurate.
(5) In the installation process, always use the positioning line at the end of the plate to ensure the parallelism of the color coating roll itself and its perpendicularity to the gutter.
In the installation process, the following points should be paid special attention to:
(1) for the support of the purlin, its top must be on the same plane, according to the actual situation needs, using flapping or relaxing way, adjust its position to achieve this requirement, must not directly hit the lower fixed bracket to try to adjust the roof slope or position, the color roll placed correctly, can ensure its effective buckle, on the contrary, If the color roll is not properly placed, it will affect the buckle effect of the color roll, especially the part close to the center of the support.
(2) In order to avoid improper construction and make the color roll fan or spread or the roof edge uneven, installed in the color roll should be at any time to check whether the color roll is appropriate, at any time to measure the edge of the upper and lower ends of the color roll to the gutter distance is equal to avoid the color roll oblique.
(3) Immediately after installation, clean the residual water debris, rivet rod, discarded fasteners and other metal debris on the roof, because these metal debris will cause corrosion of color coating roll.
Wrap Angle, flooding and other accessories construction
2. Laying of thermal insulation cotton:
Before laying, check whether the thickness of the thermal insulation foam is uniform and whether the warranty and certificate of qualification meet the design requirements.
The insulation foam should be laid tightly. There should be no gaps between the insulation foam and secure it in time.
3. Laying of the roof:
When the inner and outer panels of the roof are laid, the lapping of each edge shall be carried out in strict accordance with the standard requirements. When installing the cornice, the installation position shall be determined based on the bottom plate and glass wool, and the installation position shall be laid in sequence from the bottom up to the cornice, and the flatness of both ends and the flatness of the board shall be checked to ensure the installation quality.
4, in the ridge, gutter and other local soft waterproof can be laid by SAR-PVC waterproof coil, which can effectively solve the problem of cracks and water leakage that can not be solved because of the color plate structure waterproof.
The fixing point of the PVC coil is fixed on the peak surface of the pressure plate to ensure the reasonable force of the fixed parts and the reasonable waterproof structure.
5. Installation and control of steel plate:
① The installation of the pressed metal plate should be smooth and straight, and the surface of the plate should not have construction residues and dirt. Cornice and the lower end of the wall should be in a straight line, there should be no untreated wrong drilling holes.
② Check quantity: according to the area of 10% spot check, and should not be less than 10 square meters.
③ Inspection method: observation inspection
④ Deviation of pressure type metal plate installation:
⑤ The permissible deviation of pressure metal plate installation should conform to the provisions of the following table.
⑥ Inspection quantity: cornice and ridge parallel degree: according to the length of 10% spot check, and should not be less than 10m. Other items: one spot check should be made every 20m length, and no less than two spots should be made.
⑦ Inspection method: with cable, suspension line and steel ruler inspection.
