Firstly, most of the ceilings used in interior decoration projects are suspended ceilings. The first thing to do is to pay attention to the selection of materials. In addition, we must strictly follow the construction specifications. When installing, we must have a correct position and a firm connection. The decorative materials used for ceilings, walls, and floors should be non-combustible or non-flammable materials. Wood materials are flammable, so fire prevention should be done. Generally, ceilings should be laid with electrical lines such as lighting and air conditioning, and they should be operated strictly in accordance with the regulations to avoid potential fire hazards.
Second, the kitchen, bathroom ceiling should use metal, plastic and other materials. The bathroom is a place for bathing and washing. In the kitchen, it is necessary to cook and stir the dishes. Although the range hood and the exhaust fan are installed, the steam cannot be completely drained. The veneer or the paint that absorbs moisture will deform and peel. Therefore, materials that do not absorb moisture should be used. Generally, metal or plastic gussets should be used. If other materials are used for ceilings, measures should be taken to prevent moisture, such as brush painting.
Third, manholes should be provided with manholes. In the home decoration, the ceiling is generally not provided with an inspection hole, and it is considered to be aesthetically pleasing. I wonder if once the pipeline equipment in the ceiling fails, it can not be checked to determine what part, what is the reason, and it cannot be repaired. Therefore, the ceiling for laying pipelines is also provided with an inspection hole. For better, choose a more concealed and easy-to-check location, and articulate the manhole, such as with a fixture or fixture.
Fourth, glass or light box ceilings should use safety glass. The use of colorful colored glass and frosted glass as ceilings is very characteristic. There are more and more applications in home decoration. However, if the materials are not properly used, safety accidents are likely to occur. In order to use safety, safety glass should be used on ceilings and other vulnerable parts. At present, China's toughened glass and laminated glass are safety glasses.
For the concrete basement ceiling, it must be ensured that the foundation layer is clean and firmly bonded to the base ash without hollowing. The surface of the suspended ceiling is smooth and smooth with no bubbles, peeling or cracks.
1. For wooden ceilings, the wooden keel must be free from knots, the booms should be firmly connected to the wooden keel and the floor slabs, and the keel should be coated with fire-resistant and corrosion-resistant paint. The cover panel of the entire ceiling should be smooth, free from warping, peeling, and degumming.
2. For light steel keel ceilings, ensure that the positions of the keel, suspenders, and connectors are correct, the materials are smooth, straight, and the links are firm. No looseness can occur. The boom should not exceed 30 cm from the end of the main keel. The center should arch 1/200 from the short side.
3. For wooden suspended ceilings, it must be ensured that the hanging points, booms, metal pipes, and wooden fences are made firmly and firmly connected. The entire top surface is flat and smooth, with an accurate size.
4, for the plastic buckle ceiling, should be neat, straight, no color, no deformation and smudges. Panels, lamps, walls, etc. shall be tightly closed with no leaks, and light fixtures and ventilation fans shall be closely connected with the keel.
