Problems solved by technology

[0003] Concrete materials are composed of cement, fine sand, stones and concrete admixtures. Most of the pouring concrete is manually vibrated with vibrating rods. However, during the pouring process of reinforced concrete molds, manual vibration is easy to make The steel bars are displaced during this process, so that after the model is formed, the grip force of the concrete on the steel bars will be reduced, and gaps may appear, which will affect the quality of the concrete molding

Embodiment 1

[0046] The embodiment of the present invention provides a preprocessing process of prefabricated building materials with high uniformity and high density. The preprocessing process of prefabricated building materials with high uniformity and high density can be obtained through the following preparation steps: Please refer to figure 1 ;

[0047] S1: Crushing: A certain amount of cement, sand, and stone are crushed to form concrete raw materials; the raw materials are crushed to reduce the impact of excessive sand and stone on the quality of concrete in the later stage.

[0048] S2: Mixing: artificial stone made by adding appropriate amount of water and aggregate to concrete cement raw materials, and then uniformly stirring;

[0049] S3: Proportion: cement sand, stone and admixtures have been inspected to meet the requirements of relevant standards. The compounding ratio is: cement: sand: gravel: water = 350:792:1008:200; the cement is ordinary Portland 32.5 cement, cement The...

Abstract

The invention belongs to the technical field of building pouring, and relates to a pre-machining technology of a high-uniformity and high-compactness building prefabricated building material. After concrete is pre-melted, a concrete mold on pre-machining equipment is installed in place, and before the mold is erected, a lower opening in the lower end of the concrete mold needs to be installed for pouring and three-time vibrating. The pre-machining equipment comprises a base, a tray, a concrete mold, a first vibrating assembly, a second vibrating assembly and a vibrating assembly; the first vibrating assembly is installed at the upper end of the base, the tray is installed at the upper end of the first vibrating assembly, the concrete mold and the second vibrating assembly are both installed in the tray, the second vibrating assembly is installed at the gap position between the concrete mold and the tray, and the vibrating assembly is installed in the concrete mold. The concrete mold vibrates for three times during pouring, so that the concrete is promoted to be tightly attached to a steel bar prefabricated part, and the plasticity of the concrete is enhanced.

Description

technical field [0001] The invention belongs to the technical field of building pouring, and in particular relates to a preprocessing process of prefabricated building materials with high uniformity and high density. Background technique [0002] The preprocessing technology of prefabricated building materials with high uniformity and high density refers to the concrete products processed and produced in the factory through standardized and mechanized methods. Correspondingly, traditional cast-in-place concrete requires on-site molding, on-site pouring and on-site maintenance. Prefabricated building materials with high uniformity and high density are widely used in construction, transportation, water conservancy and other fields, such as prefabricated floors, prefabricated beams, prefabricated walls, prefabricated columns, prefabricated stairs and other complex heterogeneous components. In the process of prefabrication, concrete pouring construction plays a pivotal role in ...
