Prefabricated hollow plate mold and method for manufacturing prefabricated hollow plate through using mold

Abstract

The invention discloses a prefabricated hollow plate mold. The prefabricated hollow plate mold comprises a bottom plate arranged on a base, side molds and an inner mold part, wherein the side molds and the inner mold part are arranged on the bottom plate; the bottom plate comprises a first bottom plate and a second bottom plate, wherein the first bottom plate and the second bottom plate are arranged in a laminated mode, and a welding hole formed in the second bottom plate is connected with the first bottom plate through plug welding; the plurality of side molds are arranged fixedly on the second bottom plate to form a pouring area on the second bottom plate in a surrounding mode; and the inner mold part is positioned in the pouring area, and the bottom of the inner mold part is fixed on the first bottom plate after passing through a positioning hole formed in the second bottom plate. The prefabricated hollow plate mold is formed by assembling the bottom plates, the side molds and the inner mold part, independent parts can adopt metal components, the manufacturing way of integral forming is not needed, the processing and manufacturing are easy, the structural strength is high, concrete with larger weight can be borne, the mold is not easy to compress or crush, a prefabricated hollow plate can slide out through disassembling the side molds, loosening the inner mold part, and inclining the bottom plates, the demolding is easy, and the processing speed is improved.

Description

technical field [0001] The invention belongs to the field of prefabricated concrete components, in particular to a prefabricated hollow plate mold and a method for manufacturing a prefabricated hollow plate using the mold. Background technique [0002] Prefabricated hollow slab is a common concrete prefabricated part, which is often used as the cover of the drainage ditch, or directly as the roof of the building, so that the water can pass through the hollow part, fall and drain, and at the same time, it is convenient for people to step on it. [0003] At present, the molds for processing and manufacturing prefabricated hollow panels are mainly integrated molds made of plastics. The main body of the mold is a groove, and protrusions are arranged in the groove. When in use, steel bars are laid in the mold, and then concrete is poured into the mold, and the protrusion passes through the concrete poured into the mold to form a hollow structure. After the concrete is solidified,...

AI Technical Summary

Problems solved by technology

When the size of the prefabricated hollow slab to be processed is large, the weight of the prefabricated hollow slab is relatively large due to the large amount of concrete to be filled, and the integrated mold itself is weak in strength and cannot bear the weight of the concrete. The bottom and side of the integrated mold The part is easily crushed or crushed by concrete, and it is difficult to turn over and demould
