Technical Field
[0001] The utility model relates to the technical field of phosphogypsum mould box devices, in particular to a phosphorus building gypsum mould box. Background Art
[0002] Phosphogypsum is a waste product from the production of phosphate fertilizers. Phosphorus building gypsum mold boxes are building filling materials made of phosphogypsum. The phosphorus building gypsum mold boxes are buried in the cast-in-place concrete floor slab. After pouring the concrete, the gypsum mold boxes will continuously release water to the concrete for curing during the solidification process, playing the role of built-in curing, thereby increasing the compressive strength of the concrete and enhancing the bond strength of the concrete to the steel bars. After the concrete solidifies and hardens, a hollow floor slab is formed, which not only saves a lot of concrete, but also has good load-bearing and sound insulation effects and low cost. It is widely used in public buildings, shopping malls, schools, high-rise buildings, large-span beamless floors and other construction systems.
[0003] The existing phosphorus building gypsum mold box has the following problems in use: first, the upper box body and the lower box body are easily misaligned during the process of splicing, laying steel bars and pouring concrete, and repeated inspection and adjustment are required. The misalignment will affect the shaping effect of the subsequent concrete pouring; second, during the process of laying and fixing steel bars on the upper and lower sides of the phosphorus building gypsum mold box, the steel bars will cause wear on the top and surface of the phosphorus building gypsum mold box. Therefore, the present application proposes a phosphorus building gypsum mold box. Utility Model Content

[0021] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.
[0022] The utility model discloses a phosphorus building gypsum mold box, referring to Figure 1-5The phosphorus building gypsum mold box comprises an upper box body 1 and a lower box body 2 formed of phosphorus gypsum, wherein a cavity 3 is provided in the upper box body 1 and the lower box body 2, and a docking surface 4 and a limit platform 5 are integrally formed on the box openings of the upper box body 1 and the lower box body 2, and the docking surface 4 and the limit platform 5 of the upper box body 1 and the lower box body 2 are correspondingly arranged and the concave and convex parts match each other.
[0023] The upper box body 1 and the lower box body 2 can be assembled to form a box body with a hollow interior. When assembled, the docking surfaces 4 and the limit platform 5 of the upper box body 1 and the lower box body 2 are concavely matched, so that the limit platform 5 and the docking surface 4 of the upper box body 1 are respectively matched with the docking surface 4 and the limit platform 5 of the lower box body 2 to avoid misalignment and offset. The assembled upper box body 1 and the lower box body 2 are laid between the steel mesh surfaces and concrete is poured, which has the effects of heat preservation, sound insulation and weight reduction. After pouring the concrete, the gypsum mold box will continuously release water to the concrete for maintenance during the solidification process, thereby increasing the compressive strength of the concrete and enhancing the grip of the concrete on the steel bars. After the concrete solidifies and hardens, a hollow floor slab is formed.
[0024] See also Figure 1-5 The docking surface 4 and the limit platform 5 are arranged in a group on each side of the box opening, and the docking surface 4 and the limit platform 5 on the opposite side are arranged in opposite directions, so that the upper box body 1 and the lower box body 2 can be assembled to form a mortise and tenon structure that is not easy to dislocate, which can not only avoid dislocation during installation, but also enhance the closing stability of the box body.
[0025] See also Figure 1-5 The cavity 3 is an arc-shaped arched cavity inside the upper box body 1 and the lower box body 2, which can enhance the strength of the hollow box body formed after the upper box body 1 and the lower box body 2 are assembled.
[0026] See also Figure 1-5 A reinforcing beam 31 is arranged in the cavity 3, which can improve the load-bearing and force-bearing effects of the upper box body 1 and the lower box body 2.
[0027] See also Figure 1-5 The top surface of the upper box body 1 and the bottom surface of the lower box body 2 are provided with raised concrete protection belts 6, which can contact with the steel bars for buffering during the laying of steel bars, thereby avoiding friction damage to the surface of the phosphogypsum mold box during the laying of steel bars.
[0028] Working process:
[0029] After the upper box body 1 and the lower box body 2 are assembled into a complete box body through the docking surface 4 and the limit platform 5, the phosphorus building gypsum mold box is evenly laid between the two layers of steel mesh. During the laying process, the concrete protection belt 6 is in contact with the steel bars. After the laying is completed, water is poured. The phosphorus building gypsum mold box is buried in the floor slab after pouring concrete. After the concrete is poured, the gypsum mold box will continuously release water to the concrete for curing during the solidification process, which plays a role of built-in curing, thereby increasing the compressive strength of the concrete and enhancing the grip of the concrete on the steel bars. After the concrete solidifies and hardens, a hollow floor slab is formed.
