Description

Technical Field

[0001] The utility model belongs to the field of concrete material forming, and in particular relates to a prefabricated composite plate anti-leakage slurry structure. Background Art

[0002] Precast composite slabs usually require side formwork to assist in forming, but precast composite slabs require a lot of exposed steel bars that pass through the side formwork. To facilitate production, a U-shaped notch is usually required on the side formwork so that the steel bars can extend outside the side formwork. However, during the production process, concrete can easily leak at the U-shaped notch.

[0003] China's patent announcement number "CN214561768U", the patent name "A leak-proof device for concrete slurry on the side form of a prefabricated composite slab", discloses a leak-proof structure, but the structure is difficult to install and very cumbersome to disassemble, has low production efficiency, and increases production costs. Utility Model Content

[0004] In view of the above-mentioned prior art, the purpose of the present invention is to provide a prefabricated composite board anti-leakage slurry structure with higher production efficiency.

[0005] The technical solution of the present invention is achieved as follows: the prefabricated composite slab leakage prevention structure includes a side mold, steel bars and a leakage prevention belt. The side mold is provided with multiple steel bar grooves, which can accommodate steel bars protruding relative to the side mold. The leakage prevention belt is fixed to the inner side of the side mold and covers the steel bar grooves.

[0006] The beneficial effects of this design are: the leak-proof tape can cover multiple steel bar grooves at one time, which is easy to install. Even if the leak-proof tape adheres to the prefabricated composite board after casting, it can be removed at one time. Compared with the existing technology, both assembly and disassembly are very convenient, so it can greatly improve production efficiency and reduce production costs.

[0007] Furthermore, the leak-proof belt is made of flexible material, which has a better sealing effect on the steel bar groove during installation, is more convenient to disassemble, and is easier to seal the steel bar groove.

[0008] Furthermore, at least one side of the leak-proof belt is provided with an uneven surface. The uneven surface in contact with the concrete can produce a roughened effect on the prefabricated composite board, making it easier to cast together with other prefabricated composite boards. The other side of the leak-proof belt is a flat surface, which makes it easier to fix it to the side form.

[0009] Furthermore, the anti-leakage belt is an anti-slip conveyor belt with an uneven pattern on one side. The conveyor belt is easy to purchase, which can reduce the cost of developing and producing the anti-leakage belt. Moreover, the anti-slip conveyor belt with the uneven pattern has high strength to meet production needs and is not easily damaged after repeated use.

[0010] Furthermore, a semicircular notch is provided below the leak-proof belt, so that it matches the steel bar more closely and reduces leakage.

[0011] Furthermore, a circular hole is provided below the leak-proof belt, so that the leak-proof belt can be put on the steel bar first and then fixed to the side form, which has a better leak-proof effect.

[0012] Furthermore, a gap is provided below the circular hole and connected to the lower end, so that the steel bar can enter the circular hole through the gap.

[0013] Furthermore, the side formwork is a triangular iron structure including upright plates and support plates, and the steel bar grooves are arranged at equal intervals on the upright plates, and the spacing of the steel bar grooves is smaller than the spacing of the steel bars. In this way, the same side formwork can adapt to more prefabricated laminated plates with different steel bar densities.

[0014] Furthermore, the leak-proof tape is adhered to the inner side of the upright plate by adhesive, which is convenient for temporary fixation. When pouring concrete, the leak-proof tape will be squeezed to make it more secure.

[0015] Furthermore, locking nails are provided on the outside of the anti-leakage belt, and the locking nails pass through the steel bar grooves to fix the anti-leakage belt to the upright plate, so as to prevent the anti-leakage belt from detaching from the side mold in the event of accidental force.
