Children’s room ceiling 1. Light steel keel gypsum board ceiling
Gypsum board is made of plaster of Paris as the main raw material, mixed with additives and fibers, and has the properties of light weight, heat insulation, sound absorption, non-combustibility and sawnability. The combination of gypsum board and light steel keel (compressed by galvanized thin steel) forms a light steel keel gypsum board. There are many types of light steel keel gypsum board ceilings, including paper-faced gypsum board, decorative gypsum board, fiber gypsum board, and hollow gypsum board. There are many specifications on the market. From the current point of view, the use of light steel keel gypsum board ceilings for partition walls is more common, but less for modeling ceilings.
2, gypsum board ceiling
is mostly used in commercial spaces, generally use 600×600 (mm, the length of the unit is not specified in the project, the unit is mm) specifications, there are clear bones and dark bones. The keel is usually aluminum or iron.
3, splint ceiling
is commonly used for current decoration. Plywood (also called plywood) is made by steaming and softening the logs, cutting them into large sheets along the annual rings, and then drying, finishing, gluing, assembling, hot pressing, and sawing. It has light material, high strength, good elasticity and toughness, impact and vibration resistance. Easy processing and finishing, insulation and other advantages. 5 cm plywood is generally used for smallpox. The thickness of 3 cm is too thin, and the thickness of 9 cm is too thick. The reason for its popularity is that it can easily create various shapes of ceilings, including curved, round and square ones. But there is a disadvantage: fear of termites. The remedy is to spray anti-termite potion. The plywood ceiling may fall off after some time is spent using paint. The method is to apply varnish (varnish) first when decorating, and then do another process after it dries. The disadvantage of another type of splint is that the joints will crack. The method is to use putty to repair the joints during decoration.
4, aluminum honeycomb perforated sound-absorbing panel ceiling
Its structural structure is a perforated panel and a perforated back panel, which rely on high-quality adhesives to directly bond the aluminum honeycomb core to form an aluminum honeycomb sandwich structure. A layer of sound-absorbing cloth is pasted between the honeycomb core, the panel and the back panel. Since the honeycomb core in the honeycomb aluminum plate is divided into numerous closed cells, the air flow is prevented, the sound wave is obstructed, the sound absorption coefficient is improved (up to 0.9), and the strength of the plate itself is improved, so that the size of the single plate can be To be bigger, and to further increase the design freedom. According to the design of the room acoustics, different perforation rates can be designed, and the sound absorption coefficient of the combined structure can be controlled within a certain range, which not only achieves the design effect, but also can reasonably control the cost. By controlling the perforation aperture and distance, the perforation rate can be changed according to the customer’s requirements. The maximum perforation rate is less than 30%. The aperture is generally selected as ∮2.0, ∮2.5, ∮3.0 and other specifications. The backplane perforation requirements are the same as the panel, and the sound-absorbing cloth is used High-quality non-woven fabrics and other sound-absorbing materials. It is suitable for sound-absorbing wall panels and ceiling panels of large public buildings such as subways, theaters, radio stations, television stations, textile mills, and noise-exceeding standard factories and stadiums.
