A prefabricated overhead leveling ground and its production method and installation method

Abstract

The invention relates to the technical field of architectural decoration, in particular to an assembled overhead leveling ground and its production method and installation method, comprising a block load-bearing panel and an adjustable support assembly; The inner wall of the through hole is provided with threads, and the through hole is adjacent to a glue injection port; the adjustable support assembly includes a base and a support column, the bottom of the support column is fixedly connected with the base, and the top is provided for adjustment. Threads are provided on the side of the support column of the notch, and the support column is threadedly connected with the through hole. The invention realizes rapid assembly and convenient leveling, and the prepared block-shaped load-bearing panel is light in weight, high in strength, strong in stability, good in bearing capacity, simple in installation and operation, and has better effects of leveling, overhead, sound insulation, moisture insulation and heat preservation.

Problems solved by technology

[0002] Indoor and outdoor decoration, the ground or wall base of existing buildings needs to be leveled. Traditionally, cement mortar leveling, wooden base leveling, and light steel keel leveling are used. In these leveling methods, either cannot be quickly leveled, the height cannot be adjusted, or it is a waste of space The operation is complicated and difficult to apply in practice. At the same time, in some occasions with high humidity and high noise requirements, these methods cannot achieve effective sound insulation, moisture insulation and heat preservation effects.

[0003] In the prior art, there are metal brackets and gusset plate overhead leveling techniques, some of which cannot be adjusted in height, and some adjustments are made by adjusting the bracket before installation, and cannot be adjusted from the surface of the gusset plate after the paving is completed. It is very inconvenient to carry out fine adjustment unless it is demolished. In addition, due to the unstable connection between the bracket and the buckle plate, the assembly is complicated and troublesome, and the selection of the bracket position is laborious and laborious;

[0004] Secondly, the shell of the all-steel network raised floor in the prior art is made of cold-rolled steel after stretching, spot welding, phosphating, and plastic spraying, and the inner cavity is filled with foamed cement, whether it is the phosphating process or the plastic spraying process. The process of filling the inner cavity with foamed cement is extremely unenvironmental, and the phosphating and spraying is a pollutant process that the country must shut down. , the thinnest thickness of 500 squares is also 28mm, and each piece weighs 10kg, that is, it weighs 40kg per square meter, which greatly exceeds the national standard requirements for material and energy conservation. It is already a super energy-consuming product, such as ceramic veneer overhead Raised floor: This kind of ceramic veneer floor is made by mixing cement and glue, then compounding the tiles with the steel plate after grouting or adding reinforcement ribs at the bottom of the floor, punching holes on the surface of the steel plate, fixing the tiles and the steel shell, and then one-time cement grouting. No matter what kind of grouting, a lot of non-environmentally friendly materials such as cement and ceramic tiles are used, and the weight is heavier, up to more than 50 kg per square meter. Wood-based raised floor: high-strength wood-based raised raised floor is made of high-density flame-retardant particleboard substrate, the surface is glued to PVC, and the bottom is made of galvanized steel back cover.

The high-strength particleboard is 720kg per cubic meter, and the floor produced in this way needs 40kg per square meter to meet the overhead requirements. Moreover, the particleboard is not environmentally friendly, contains a lot of formaldehyde, and is not waterproof and moisture-proof. After adding flame retardants, it can only reach B2 grade, and the added flame retardant will evaporate over time in about 8 months, thus losing the flame retardant function and playing a role in supporting combustion and flammability. For example, calcium sulfate raised access floor: calcium sulfate raised raised floor base The material is high-strength calcium sulfate board, the surface is PVC veneer, and the bottom is galvanized steel plate. The thinnest floor of this kind of floor needs to be 30 cm thick to meet the overhead strength requirements. Too heavy, increasing the load of the building, causing a huge load on the load of the building, which is extremely energy-saving

At the same time, the size and specification are single, which will cause a lot of cutting garbage during paving, and also increase the cost of cleaning garbage

Furthermore, the calcium sulfate board will burst in case of a fire with a high temperature of more than 800 degrees. After the burst, the support of the entire raised floor will be lost and collapsed, causing an accident.
