There are many types of prefabricated components on the market, and the cost and difficulty of prefabrication are high. Prefabricated dense-rib cavity panels are widely used in large-span and irregular floor slabs because of their miniaturization and flexibility.

[0003] Prefabricated ribbed cavity floor technology is a new type of floor. Ribbed cavity floor is composed of small prefabricated components (prefabricated cavity components assembled from prefabricated reinforced concrete bottom plate, top plate and side plates made of hard materials).

[0004] The length and width of the standard bottom plate and top plate are both 1m, while the length of non-standard parts is 1m and the width is 0.8m or 0.5m. The concrete strength grade of the top plate and bottom plate is C30. The top plate is 50mm thick, and the steel bars are ribbed steel bars with a diameter of not less than 6mm and a spacing of not more than 200mm; the bottom plate is 40mm thick, and the steel bars can be round steel bars with a diameter of not less than 5mm and a spacing of not more than 200mm. The side plate is a 12mm thick cement pressure plate, which is fixed on four vertical poles by metal parts to form a side plate frame, and the side frame is fixed in position by positioning strips set on the bottom plate. The top plate of the component is mainly supported on the bottom plate by four vertical poles. After the top plate, side plate and bottom plate are connected and assembled, they should have sufficient bearing capacity, rigidity and stability and should be able to withstand construction loads. The top plate and bottom plate steel bars of the prefabricated dense rib cavity component extend outward and are anchored in the cast-in-place concrete structure.

Its structural design and calculation are simple, and its seismic performance is equivalent to that of cast-in-place structures. It is now widely used in heavy-load, large-span, and large-bay prefabricated buildings. At the same time, due to its relatively uniform specifications, safe and convenient hoisting construction, and easy control of production and construction quality.

The wooden planks are fixed randomly and cannot be precisely controlled, and the wooden planks need to be treated with anti-corrosion. Utility Model Content
