Preparation process of concrete precast element

Abstract

The invention relates to the field of concrete structures, in particular to a preparation process of a concrete precast element. The preparation process comprises the following steps that S1, a mold is prepared in advance, a mold cavity I and a mold cavity II are formed in the mold, and concrete is prepared in a storage tank; S2, the concrete is injected into the mold cavity I through the storage tank, so that the mold cavity I is filled with the concrete; S3, the concrete is injected into the mold cavity II through the storage tank, meanwhile, water is injected till the mold cavity II is filled with the water, and the concrete in the mold cavity II is stirred to be uniform; and a forming step is conducted, specifically, waiting for solidification of the concrete in the mold cavity I and the mold cavity II. According to the preparation process, two kinds of concrete precast elements with different water contents can be produced at a time, only one mold and one storage tank are used, the occupied area of equipment can be reduced, waste caused when concrete raw materials are not used up is reduced, and the preparation process has the advantages of energy conservation and environmental protection; fasteners are embedded into the concrete precast elements, so that hoisting and mounting of the concrete precast elements are facilitated; and the connection strength of the fasteners and the concrete precast elements is high.

Description

technical field [0001] The present application relates to the field of concrete structures, in particular to the preparation process of concrete prefabricated components. Background technique [0002] Prefabricated concrete components are prefabricated building components outside the construction site, which can be directly installed in the building for use, which has the advantage of saving on-site construction time, and has better quality as a prefabricated component. [0003] The Chinese utility model patent with the authorized notification number CN208305325U discloses a mold for precast concrete components, including a base, a plurality of formworks are arranged on the top surface of the base, and a plurality of formworks form a concrete prefabricated mold, and the top surface of the base outside the formwork is provided with a formwork support pieces, the flexible connection between the formwork support and the top surface of the base. [0004] In view of the above-me...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that when producing two kinds of concrete prefabricated parts with different moisture contents, two kinds of molds need to be used, and concrete is poured into the two molds through two hoppers with different concrete contents, and the equipment occupies a large area. 1. The serious defect of waste when the concrete raw materials in the two hoppers cannot be used up
