House ceiling is an important part of modern interior decoration, which is another main part of the enclosed interior space in addition to the wall and ground. Its decoration effect directly affects the decoration effect of the whole building space. The ceiling also has the functions of absorbing and reflecting sound, installing lighting, ventilation and fire prevention equipment. It has two forms: direct type and suspended type.
Other decorative materials are pasted directly on the bottom of the floor. It is generally used in residential buildings, office buildings and other civil buildings with low decorative requirements.
According to the different construction methods and decorative materials, there are two ways to directly paste the ceiling: one is to lay the decorative materials on the formwork when supporting the formwork, and then cast the concrete in situ to make the decorative materials directly stick to the concrete, which can be used as the decorative surface after removing the formwork. This kind of decoration uses plates, such as dry plastering plate, profiled steel plate, etc. Second, after the installation of concrete components and the removal of cast-in-place concrete formwork, clean the base surface, and paste the decorative surface with adhesive, such as gypsum board (decorative board and strip board), marble board, laser glass, etc.
Suspended ceiling, also known as ceiling, ceiling, ceiling and flat roof, is an important part of interior decoration engineering. The utility model has the functions of heat preservation, heat insulation, sound insulation and sound absorption, and can increase the indoor brightness and beauty. For the design of air-conditioned buildings, it is also a fundamental way to save energy.
According to the location, the suspended ceiling is divided into the suspended ceiling under the roof truss and the suspended ceiling under the concrete slab: according to the structural form, it is divided into the movable assembled suspended ceiling, the concealed assembled suspended ceiling, the metal decorative plate suspended ceiling, the open suspended ceiling and the integral suspended ceiling (gray lath suspended ceiling), etc.
