The color steel plate coating is a product obtained by subjecting a cold-rolled steel plate or a galvanized steel sheet to a surface chemical treatment (roll coating) or a composite organic film (such as a PVC film) and then baking and curing. Some people call this product “pre-rolled color steel plate” and “plastic color steel plate”. Color plate products are produced by the manufacturer on a continuous production line, so it is also called color coated steel coil.
The color steel plate not only has the mechanical strength of the steel material, the easy forming property, but also the good decorative and corrosion resistance of the coating material. Color steel plates are emerging materials that are highly respected in the world today. With the advancement of science and technology, the enhancement of environmental awareness, and the improvement of people’s living standards, the color steel plate activity room has become more and more powerful and has broad market prospects. It is subject to construction, home appliances, electromechanical, transportation, interior decoration and office equipment. And the favor of other industries.
Color steel plate installation steps
1. Dig the trough first, then the foundation, the brick foundation, and of course the foundation, depending on the situation. After that, the movable steel frame is installed. If it is multi-layer, install the prefabricated floor and then install the color steel plate. After the first floor is completed, the doors and windows are installed and the interior is finally finished.
2. The color steel plate activity room is similar to the building, first level the perimeter and the partition wall. It is best to use reinforced concrete, which is relatively strong. Then set up the column, connect the skeleton with the transverse beam, the upper partition, the outer wall panel and the door and window frame; follow the floor and then put up a layer. Then go to the roof truss and roof slab; finally install the doors and windows, etc., pull the vertical support, then the sanitary ware, hardware and the like.
3. The concealed project of the color steel plate movable room refers to the part that will be covered by the next process after the completion of the previous process in the construction process, and all the inspections cannot be carried out after completion. To do room decoration, “concealed project” is the key. If the “concealed project” is not done well, the surface decoration is beautiful and futile. The “concealed project” is divided into water installation, electric installation, moisture-proof and waterproof projects, and each of these projects cannot be ignored. If there is a problem with any link, it may bring serious economic losses. It even hurts personal safety.
4. After the completion of the color steel plate activity room, the roof and the wall surface should be leveled, and the ridge, gable and the lower end of the wall should be in a straight line; the flooding parts should be in a straight line; whether the connecting parts are in a straight line and the horizontal line; Connected into a straight line, the plates are sewn into a straight line, and are perpendicular or parallel to the relevant axes; the color plates should have the same color and color, no pollution, and the damage should be repaired in time; ensure the fastening of the connecting parts without looseness, and the board surface is not fastened. The phenomenon of embossing; the color plate surface has no wrinkles, and there is no wrong punching.
Color steel plate installation matters
1. When lifting the steel plate, use a wooden board or a soft material to pad between the steel plate and the steel cable to prevent the steel plate from being scratched or deformed.
2. Check the appearance quality before installing the steel plate to ensure that there are no defects such as oil, sand, cracks, peeling and scratches on the surface.
3. The ribbed joints laid on the steel plate should be opposite to the local wind direction.
4. The length of the long layer of the lower steel plate is 80-100mm. The joint is not required to be sealed. From the bottom, the joint of the profiled steel plate should form a straight line parallel to the mouth and the joint should be even and tight.
5. The upper laminated steel plate should be bent upward at an angle of 80° at one end of the ridge. The length of the long laminated length of the upper laminated steel plate should be greater than 200 mm, and the sealing glue is required at the joint. From the above, the joint of the profiled steel plate should form a straight line parallel to the mouth and the joint should be even and tight.
6. The overlap length of the flooding board and the angled board should be no less than 100mm, and the sealing part should be sealed. The flooding plate, the angled plate and the profiled steel plate are connected by rivets. The distance between the longitudinal and transverse joints shall not exceed 1250px. The spacing shall be uniform. The joints on both sides shall be symmetrical, and the rivet shall be sealed with sealant.
7. The joint between the sink, gable flooding board and concrete or brick parapet wall should be cut by the cutting machine to cut the gap of the daughter wall to a depth greater than 10mm, then insert the folded edge of the flooding board into the gap and brush the sealant. . Fix the flooding plate to the daughter’s wall with cement nails and seal the cement nail head with sealant.
8. Using a special self-tapping gun to play the self-tapping screws, each row of self-tapping screws must be lined, so that a row of self-tapping screws form a straight line, and parallel with the ridge or mouth, to prevent drilling the wrong hole, self-tapping screws should It is perpendicular to the connecting surface of the purlin and the roof panel.
9. During the installation process, a fixed section inspection is carried out to check the flatness and parallelism of the two ends of the steel plate.
The above is the entire installation of the color steel plate and the precautions for everyone. I also hope that the above content can help everyone, and also remind everyone to maintain regular maintenance during use to avoid problems.
