Description

A kind of gypsum cavity mold box and its production mold

technical field

The invention belongs to the field of building materials, in particular to a gypsum cavity mold box and a production mold thereof.

Background technique

Gypsum mold box is a fasting floor filling material made of building β-gypsum powder processed by industrial by-product gypsum such as flue gas desulfurization gypsum and phosphogypsum in power plants. It is a common fasting floor filling material developed in recent years, such as thin-walled pipe, A substitute for cement-covered boxes, etc. Gypsum formwork is a new type of lightweight, environmentally friendly beamless floor slab hollow material. It is buried in the cast-in-place concrete floor slab to make it a hollow slab, and a composite floor slab with high bearing capacity and high performance is constructed, which not only saves a lot Reinforced concrete material, and retain the excellent characteristics of gypsum in the floor. It has strong advantages in technical rationality, structural uniformity, material saving, safety and environmental protection, energy saving and consumption reduction, so it is widely used in public buildings, shopping malls, squares, garages, classrooms, multi-storey factory buildings, etc. Load, long-span beamless floor building system has been widely used. Because the gypsum mold box maintains the characteristics of gypsum, it has the advantages of heat preservation, energy saving, sound insulation, fire prevention, non-toxic, environmental protection, light weight, high strength, earthquake resistance and renewable utilization. .

The current gypsum cavity mold box mainly includes an upper cavity mold and a lower cavity mold. Both the upper cavity mold and the lower cavity mold include a closed surface and an opening, and the openings of the upper cavity mold and the lower cavity mold face each other. After docking, the cavity mold forms a closed cavity body structure. The surface area of the closed surface of the upper cavity mold and the lower cavity mold is smaller than the cross-sectional area of the opening, forming a tapered cavity body, resulting in a low cavity rate.

The current gypsum cavity mold box is easy to cause damage to the upper cavity mold and the lower cavity mold during transportation because the upper cavity mold and the lower cavity mold are both basin-shaped cavities; the basin-shaped cavity takes up More transportation space is required, which leads to a sharp reduction in the single transportation volume of the gypsum cavity mold box and increases the transportation cost. At the same time, since the upper cavity mold and the lower cavity mold are connected with flat edges, when the concrete is fully watered before pouring, it is easy to form water in the lower cavity mold, and it is necessary to drill holes to release water after the floor is formed. This method not only increases the engineering quantity, but also affects the overall structure of the floor. In addition, in order to ensure the pressure resistance of the gypsum cavity mold box, in the process of making the upper cavity mold and the lower cavity mold, it is necessary to keep its wall thickness above 4.5CM, so that the absolute The clean weight reaches 18-30KG, and the wet weight reaches 35-55KG; this also seriously increases the transportation cost of the gypsum cavity mold box and the labor intensity during installation.

Contents of the invention

The present invention intends to provide a gypsum cavity mold box to solve the problems in the prior art that the gypsum cavity mold box is combined with cavity molds, resulting in high transportation costs, large damage and inconvenient installation.

A gypsum cavity mold box in this scheme includes two solid modules, the upper surfaces of the two modules are provided with a plurality of placement slots, and the plurality of placement slots are provided with a plug for connecting the two modules. The upper and lower cavity plates on the two modules are correspondingly fastened to each other, and the fastened cavity plates form a cavity.

The working principle and beneficial effects of this scheme: when transporting, the module and the cavity plate are disassembled. Since the module is solid and not easy to be damaged, multiple modules and cavity plates can be stacked and transported. On the one hand, the handling process is more convenient. On the other hand, it also greatly reduces the transportation space occupied by the gypsum cavity mold box, which in turn helps to reduce transportation costs. During installation, the fast and firm connection between the cavity plate and the module is realized by placing the card slot. When the gypsum cavity mold box is watered before concrete pouring, the accumulation of water in the gypsum cavity mold box is avoided. In addition, when gypsum cavity mold boxes of different specifications are required, gypsum cavity mold boxes of different specifications can be produced by adjusting the size of the mold, so that the gypsum cavity mold boxes can be used more widely.

The corresponding upper and lower modules and the cavity plate are of flat structure, so as to achieve the purpose of high strength, light weight, easy handling and unbreakable single block.

The upper and lower modules and the cavity plate are independent units during production, which can be adjusted according to the required specifications, so as to achieve the purpose of producing cavity mold boxes of various specifications.

During transportation, the cavity plate and the upper and lower modules are disassembled and stacked for transportation, thereby reducing the occupation of the transportation space by the mold box, increasing the transportation volume of a single vehicle, and thus achieving the purpose of reducing transportation costs.

When installing, just assemble the cavity plate and the upper and lower modules into a box body, so as to achieve the purpose of easy and fast installation.

After installation and molding, it becomes a square-shaped large-cavity mold box, so as to achieve the purpose of increasing the cavity rate of the floor, which is conducive to saving the amount of concrete and reducing the weight of the floor.

Further, the two modules are provided with reinforcement nets. The setting of the reinforcing net helps to enhance the strength and toughness of the gypsum cavity mold box, thereby avoiding or reducing damage to the gypsum cavity mold box during handling and installation.

Further, the reinforcing mesh is glass fiber mesh, nylon mesh, brown wire mesh, barbed wire mesh, bamboo mesh or hemp mesh. Glass fiber mesh, nylon mesh, brown wire mesh, barbed wire mesh, bamboo mesh or hemp mesh are all easy to use, and have good strength and toughness.

Further, the cavity board is gypsum board, wood board, PE injection-molded board, injection-molded alloy board, cement board, foamed glass board or flame-retardant polystyrene board. Choose wood board, PE injection molding board, injection molding alloy board, cement board, foam glass board or flame-retardant polystyrene board as the cavity board, and you can choose all kinds of waste boards, which will help improve the utilization rate of waste boards, and protect the environment at the same time , reducing the production cost of the gypsum cavity mold box.

Further, the thicknesses of the two modules are both 3.5-4.5CM. The thickness of the module is set to 3.5 ~ 4.5CM, and different thicknesses are selected according to the size of the required cavity mold box; on the one hand, the strength of the module is sufficient, on the other hand, the weight of the module is reduced, so that the wet weight of a single piece The weight is reduced to 15-20KG, and the absolute weight is reduced to 11-15KG.

The production mold of the gypsum cavity mold box includes a molding frame with one end open, and the bottom of the molding frame is provided with ribs, and the ribs are located in the molding frame.

When making the gypsum cavity mold box, you only need to pour the gypsum slurry from the opening end of the molding frame into the molding frame, the gypsum slurry is filled with the molding frame and dried and shaped to get the module of the gypsum cavity mold box, and then pass through the cavity plate After assembling, the gypsum cavity mold box can be obtained.

Further, there are four ribs, and the four ribs are connected end to end in turn to form a rectangular frame. By setting four ribs and forming a rectangular frame, the generated module has a rectangular groove, which is more firmly and stably connected with the cavity plate.

It should be pointed out that the gypsum cavity mold box and its production mold in this scheme are not only used for gypsum production cavity mold box, but also can be used for PPE, foamed cement, foamed glass plate and other formable flame-retardant materials Production of cavity mold boxes.
