Description

Technical Field

[0001] The utility model relates to the technical field of building profiles, in particular to a universal mould for prefabricated floor slabs. Background Art

[0002] Prefabricated buildings refer to buildings that are assembled on site using prefabricated components. The advantages of this type of building are fast construction speed, less restrictions on climatic conditions, labor saving and improved building quality. At present, domestic prefabricated building technology is becoming more and more mature, and prefabricated floor slabs are widely used as the main components. However, traditional prefabricated floor slab molds are often made of materials such as steel, aluminum or wood. Steel and wood are heavy, and auxiliary tools such as cranes are needed for demoulding, which makes demoulding difficult. Although aluminum is light in weight, it is easy to deform and also makes demoulding difficult. Utility Model Content

[0003] In order to solve the above-mentioned problems, the utility model provides a universal mold for prefabricated floor slabs, including a folding plate, a bottom edge plate and a side plate. The folding plate is located on one edge of the bottom edge plate, the side plates are located at both ends of the bottom edge plate and are perpendicular to the bottom edge plate, and a rib notch is provided on the folding plate. The folding plate, the bottom edge plate and the side plates are all made of plastic and are integrally formed by injection molding. The bending angle α of the folding plate is 120 to 160°.

[0004] Furthermore, the bending angle α of the hemming plate is 135-145°.

[0005] Furthermore, a reinforcing rib is connected between the folding plate and the bottom edge plate.

[0006] Furthermore, the side panels are provided with mounting holes.

[0007] Furthermore, a protrusion is provided on the folding plate.

[0008] Furthermore, the height of the protrusion is 5 to 10 cm.

[0009] Furthermore, the folding plate, the bottom plate and the side plate are all made of polypropylene.

[0010] Furthermore, the folding plate, the bottom plate and the side plate are all made of polyvinyl chloride.

[0011] Furthermore, the folding plate, the bottom plate and the side plate are all made of polycarbonate.

[0012] Furthermore, the folding plate, bottom plate and side plate are all composed of upper and lower hard surface layers and a middle foam core layer. The upper and lower hard surface layers are PVC plastic, and the foam core layer is made of any one of polypropylene resin, polyvinyl chloride resin, and polycarbonate resin. The thickness of the foam core layer is greater than the thickness of the upper hard surface layer and the lower hard surface layer.

[0013] The beneficial effects are: the folding plate, bottom plate and side plate of the present application are all made of plastic material, and are formed in one piece by injection molding process, which can accurately replicate the design details, and the rib notches do not need additional processing. The universal mold for prefabricated floor slabs made of this plastic material can be quickly formed and is not easy to deform. It is light in weight and easy to carry and demold. The design of the folding plate can make the floor slab form a chamfer, which is convenient for demolding the floor slab. When the bending angle α of the folding plate is between 120 and 160°, the floor slab is easier to demold, and demolding is more labor-saving. When in use, it can be flexibly combined and assembled to prefabricate floors of different lengths and widths, while ensuring that the requirements of architectural mechanics are met, the time cost, labor cost and manufacturing cost are reduced, and the practicability is high.

[0025] Example

[0026] See also Figure 1 , Figure 1 The overall structure of the utility model is shown in FIG. Figure 1 The present embodiment provides a universal mold for prefabricated floor slabs, comprising a folding plate 1, a bottom plate 2 and a side plate 3. The folding plate 1 is located on one side of the bottom plate 2, and the side plates 3 are located at both ends of the bottom plate 2 and are perpendicular to the bottom plate 2. A rib notch 11 is provided on the folding plate 1. The folding plate 1, the bottom plate 2 and the side plates 3 are all made of plastic material, and the plastic material can be any one of polypropylene, polyvinyl chloride and polycarbonate. The entire universal mold for prefabricated floor slabs is integrally formed by injection molding. The bending angle of the folding plate 1 is 120 to 160°, and the bending angle is preferably 135 to 145°.

[0027] See also Figure 1 A reinforcing rib 4 is connected between the folding plate 1 and the bottom plate 2, and the reinforcing rib can effectively connect the folding plate 1 and the bottom plate 2 together to form a more stable overall structure and improve the stability of the entire mold. The side plate 3 is also provided with a mounting hole 31. When the mold is not long enough, multiple prefabricated floor universal molds can be connected together by using bolts and the mounting holes 31.

[0028] See also Figure 2 , Figure 2 The overall structure of the utility model is shown in FIG. Figure 2. The folding plate 1 is provided with a protrusion 12. The function of the protrusion 12 is to form a specific groove structure for the floor slab. When the thickness of the cast floor slab is not enough, it is necessary to continue to cast a new floor slab on this basis. The new concrete enters the groove and combines with the cast floor slab to significantly improve the overall structural strength and stability. If there is no protrusion 12, the newly cast floor slab and the cast floor slab will form a neat gap, affecting the overall bearing capacity and stability of the floor slab. The height of the protrusion 12 is 5 to 10 cm, which can form a groove with a depth of 5 to 10 cm. If the depth is too shallow, the cast floor slab and the newly cast floor slab will not achieve the effect of fitting together. If the depth is too deep, when there is no need to cast a new floor slab on the cast floor slab, the cast floor slab is easy to break and is not strong because the periphery is in a hollow state.

[0029] The folding plate 1, the bottom plate 2 and the side plate 3 are all composed of an upper and lower hard surface layer and a middle foam core layer. The upper and lower hard surface layers are PVC plastic, and the foam core layer is made of any one of polypropylene resin, polyvinyl chloride resin, and polycarbonate resin. The thickness of the foam core layer is greater than the thickness of the upper hard surface layer and the lower hard surface layer. The three-layer co-extrusion injection molding process is used for one-piece molding. In this way, the entire mold is waterproof, moisture-proof, not easy to absorb water and rot, will not expand and deform, has a smooth surface, does not require a release agent, and has a very good demolding effect.

[0030] In summary, the folding plates, bottom plates and side plates of the present application are all made of plastic material, which is not only easy to process and form quickly, but also lighter in weight than traditional steel molds or wooden molds, and is convenient for handling and demolding. In addition, the use of plastic material allows the folding plates, bottom plates and side plates to be integrally formed by injection molding, and the design details can be accurately replicated. For example, rib notches and protrusions do not require additional processing, thereby improving production efficiency. The design of the folding plate 1 can form chamfers on the floor slab, which is convenient for demolding the floor slab. When the bending angle α of the folding plate 1 is between 120 and 160°, the floor slab is easier to demold, and demolding is more labor-saving. When in use, it can be flexibly combined and assembled to prefabricate floor slabs of different lengths and widths, which reduces time costs, labor costs and manufacturing costs while ensuring that the requirements of architectural mechanics are met, and is highly practical.

[0031] The above is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
