Ceiling collocation knowledge
First, the style of the ceiling:
1, planar type
Planar ceiling refers to the ceiling decoration of various rooms with no shape and hierarchy on the surface, flat, simple, neat and generous top surface, and less materials than other ceiling forms. Generally, it is made by splicing various decorative boards, and it can also be painted, sprayed, pasted with wallpaper and wall cloth. (Brushing latex paint is recommended for plasterboard splicing, which is convenient for handling joint cracks. ) Jointing with wooden boards should strictly handle the interface, which must be treated with glue or epoxy resin.
2, concave and convex (usually called modeling top)
Concave-convex ceiling refers to a kind of ceiling with concave-convex structure on the surface. This kind of ceiling is complex and changeable in shape, with a strong sense of hierarchy, and is suitable for the top decoration of halls, hallways, restaurants and so on. It is usually used with lamps (chandeliers, ceiling lamps, downlights, spotlights, etc.). ).
3. Hanging type
Hanging type is a kind of suspended ceiling for hanging various plates, metals, glass, etc. In the structural layer. This kind of smallpox is full of dynamic changes, giving people a refreshing aesthetic feeling, and is often used for ceiling decoration in hotels, concert halls, exhibition halls, film and television halls, etc. Often through a variety of lighting to produce a unique shape, full of artistic interest in light and shadow.
4. Well format
Well-shaped ceiling is a kind of ceiling form that uses well-shaped beams to guide modeling or shape the top surface. Decorate with lamps and single-layer or multi-layer decorative lines to enrich the ceiling shape or reasonably divide the room.
5, glass type
The glass top surface is a form of using transparent, translucent or painted glass as the indoor top surface, which is mainly used for lighting, viewing and beautifying the environment, and is made into dome, flat roof, folding roof and other forms. It gives people a magical feeling of being bright and fresh indoors and seeing the sky.
Second, the trend of ceiling collocation:
1, light steel keel plasterboard ceiling
Gypsum board is made of gypsum ash as the main raw material, with additives and fibers. It has the properties of light weight, heat insulation, sound absorption, incombustibility and sawability. Gypsum board and light steel keel (pressed by galvanized steel sheet) are combined into light steel keel gypsum board. There are many types of light steel keel gypsum board ceiling, including paper gypsum board, decorative gypsum board, fiber gypsum board and hollow gypsum board strip. There are many specifications on the market. At present, as a partition wall, the light steel keel gypsum board ceiling is rarely used for ceiling modeling.
2, gypsum board smallpox
Mostly used in commercial space, generally 600x600(mm, the unit length is not specified in the project, and its unit is mm), which can be divided into open bone and dark bone. Keels are usually made of aluminum or iron.
3. Plywood smallpox
At present, decoration is commonly used. Plywood (also called plywood) is made by cooking and softening logs, cutting them into large pieces along the annual rings, drying, sorting, gluing, assembling blanks, hot pressing and sawing. It has the characteristics of light weight, high strength, good elasticity and toughness, and resistance to impact and vibration. Easy processing and finishing, heat preservation and the like.
Smallpox usually uses a 5 cm splint. 3 mm is too thin and easy to arch, 9 mm is too thick. The reason why it is popular is that it can easily create various shapes of smallpox, including curved, round and square. But there is one disadvantage: fear of termites. The remedy is to spray termite control drugs. Plywood ceiling may fall off after painting for a period of time. The method is to brush varnish (varnish) before decoration, and then do another process after drying. The disadvantage of another splint is that the joints will crack. The method is to fill the joints with putty when decorating.
4. Aluminum honeycomb perforated acoustic panel ceiling
Its structure is a perforated panel and a perforated back panel, which are directly bonded with the aluminum honeycomb core by high-quality glue to form an aluminum honeycomb sandwich structure, and a layer of sound-absorbing cloth is stuck between the honeycomb core, the panel and the back panel. Because the honeycomb core in the honeycomb aluminum plate is divided into many closed cells, the air flow is prevented, the sound wave is hindered, the sound absorption coefficient is improved (above 0.9), and the strength of the plate itself is improved, so that the size of the veneer can be made larger, and the design freedom is further increased. According to room acoustics design, different perforation rates can be designed, and the sound absorption coefficient of composite structure can be controlled within a certain range, which can not only achieve the design effect, but also control the cost reasonably.
By controlling the perforation aperture and spacing, the perforation rate is changed according to the customer's use requirements. The maximum perforation rate is 30%, and the aperture is generally ∮2.0, ∮2.5, ∮3.0 and other specifications. The perforation requirements of the backboard are the same as those of the panel, and the sound-absorbing cloth is made of high-quality sound-absorbing materials such as non-woven fabrics. Suitable for subways, theaters, radio stations, TV stations, textile mills, factories with excessive noise, gymnasiums and other large public buildings.
