Dimensions of Chongqing light steel keel villa
Chongqing light steel keel is a common material for decoration of suspended ceilings. It has high toughness and good fire resistance, and is a good material for construction. Chongqing light steel keel is made of galvanized steel strip or sheet steel for special rolling mill. The utility model has the advantages of high strength, good versatility, good fire resistance, simple installation, etc. It can be assembled with various gypsum boards, calcium-plastic boards, sound-absorbing boards, etc., and can be used as keel supports for wall partitions and ceilings. Widely used in various civil construction projects and textile industrial plants and other places. It has good interior decoration, sound insulation and other functions. Light steel keel sections are U-shaped, C-shaped, T-shaped and L-shaped. The ceiling joists are called D and separate the joists code Q. Ceiling keel is divided into main keel (also called keel, load-bearing keel) and keel (also called keel, including keel and keel). Keel is divided into vertical keel, horizontal keel and Tong Guan keel. There are usually two kinds of dividing keels: vertical keels and earth keels; from model to 75, 50, 100 and 150. In engineering applications, sometimes filler material, rock wool (insulation, or sound insulation), is used to isolate walls. Rock wool is divided into rock wool board and rock wool felt, which mainly play the role of heat insulation, sound insulation and heat insulation. The difference between Chongqing light steel keel and paint keel is that the general light steel keel is not coated, so that the surface of the coating (galvanized) and baking keel is made of paint, usually black and white, and a small amount is baked according to other colors . The design requirement of E is mainly because the baked keel is mostly used on the transparent keel, and the baking paint is to ensure the outside. If the dew doesn't rust, it won't affect the beauty. Mingming frame keel plane series, groove series, three-dimensional groove series. Concealed frame keel: Flat series, the overall plane effect of the painted keel is good, the lines are simple, and the appearance is elegant. The paint keel is safe, firm and beautiful, and is suitable for various mineral wool ceilings, aluminum square roofs, calcium silicate boards and other supporting constructions. It has the advantages of light weight, high strength, waterproof, fireproof, shockproof, sound insulation, sound absorption and so on. It also has the advantages of short construction time and simple construction. It is a new type of ceiling decoration material, widely used in shopping malls, hospitals, banks, hotels, factories, dock buildings, etc. The main specifications of the partition keel are Q50, Q75 and Q100. The main specifications of ceiling keel are D38, D45, D50 and D60. There is no standard for T-shaped keel and L-shaped keel, and the specifications of products produced by different manufacturers are also different. As the main joist in the ceiling joist frame, the T joist plays the role of the ceiling joist frame and decorative panel. The general specifications are 1200 mm and 3000 mm, and the keel frame (beam or cross brace) is used at the same time as the decorative plate. The auxiliary keel is also a T-shaped keel, which is relatively short, 600×600 according to the length of the decorative plate. The secondary joist used for the plasterboard ceiling is 600 mm. L-shaped joists are a type of side joist that primarily connects the frame of the ceiling to the walls of the four-sided or column wall. It is also part of the trim panel, usually a 3000mm one. The appearance quality of light steel keel should be smooth and sharp, and it is not easy to produce burrs and deformation. Galvanizing does not cause defects such as skin, tumors and shedding. For defects such as corrosion, damage, black spots, pitting, etc., the specified method shall be consistent with Table 2-81. When checking the appearance quality, visual inspection should be carried out under the strong light condition of 0.5 meters of the product. The surface of the light steel keel should be galvanized to prevent rust, and the amount of double-sided galvanizing should not be less than 120 g/m×m, which is a class. Not less than 100g/m×m, qualified products not less than 80g/m×m. As a common building material, Chongqing light steel keel plays an important role in the field of building ceilings, marking another development in the construction industry.
