Customized PP Plywood Plastic Types Concrete Formwork System
| Product Description |
Thin-walled square box, PP square box, in the cast-in-place concrete floor, there is a regular embedded internal thin-walled square box mold, so that the reinforced concrete interior forms a reinforced concrete hollow floor with two-way grid cast-in-place ribs.
The thin-walled square box is a kind. The built-in mandrel can effectively restrain the deformation and deflection of cast-in-place concrete and has the advantages of being lightweight and high strength.
The thin-walled square box is a square or rectangular thin-walled hollow small-sized fully enclosed non-through-hole box. The maximum area size is less than 600 mm*600 mm. It is convenient for the cast-in-place concrete to flow into the bottom of the square box evenly, forming a hollow floor cover.

| Engineering application example |
In the cast-in-place concrete hollow floor structure technology, a PP square box is used.
The larger span is Xuzhou Yurun Square (span 12 m), Jiufu Electronics (span 14m), Hebei Xianghe First City (span 12m), and Maple Leaf International School ( In many construction projects such as span 12m), due to the large span, the thickness of the plate and the size of the square box increase, and the construction requirements are also stricter.

Technical characteristics and advantages of hollow floor
1, Saving materials and resources
The hollow floor has a lightweight and high bearing capacity. The conversion thickness (the ratio of the conversion solid thickness to the height of the traditional beam slab floor section) is generally 25 ~ 30%, saving 15% ~ 25% steel and about 20% concrete.
2, No ceiling is required for floors
The bottom of the floor is flat without protruding beam structure. Pipelines and other facilities have been embedded in the floor during the floor construction, which will not cause the ceiling to due to the influence of pipeline installation on the floor appearance. It can improve the floor clearance height and reduce ceiling expenses.
3, Space can be separated flexibly
The floor is flat, without protruding beam structure, and the hollow floor has very dense rib beams. It can carry partition walls everywhere and can be arranged arbitrarily. Because the wall can be moved arbitrarily, it is suitable for large public buildings such as office buildings, entertainment places, exhibition halls, etc., which need to change the interval at any time.
4, Reduce floor height and increase headroom
The thickness of hollow floor is smaller than that of traditional cast-in-place concrete floor. On the premise of keeping the floor clearance height, the total floor height can be reduced, or the floor clearance height can be increased without changing the floor height to improve the spacing effect.
5, Good heat insulation and heat preservation performance
The closed cavity structure of a hollow floor can effectively reduce heat transfer and significantly improve the thermal insulation and insulation performance of buildings. Greatly reduce the operating costs of air conditioning, energy saving, and environmental protection.
6, It has a good sound insulation effect
The closed cavity structure of a hollow floor can effectively reduce the transmission of noise, overcome the noise interference between the upper and lower floors, and solve the noise problem in special places, especially the impact noise problem.
7, Excellent seismic performance
The hollow floor makes full use of the advantages of the hollow slab structure, effectively reducing the height of the structural layer and greatly reducing the weight of the structure. At the same time, the densely distributed dark ribs formed in the floor make the deformation between the upper and lower slabs coordinate, produce a "skin effect" when subjected to vibration, and consume a certain amount of vibration energy, so as to effectively improve the seismic performance of the building
