PRODUCT DETAIL

Disposable Formwork for Slabs in Reinforced Concrete Cast on Site

Thin-walled square box (PP square box), in the cast-in-place concrete floor, there is a regular embedded internal thin-walled square box mould, 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 light weight and high strength.

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 mould, 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 light weight 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 600mm*600mm. 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, 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.
