Problems solved by technology

[0003] When preparing prefabricated wall panels, after the staff pours concrete into the mold, during the curing process of the prefabricated wall panels, the concrete is solidified and formed. During the solidification process, the prefabricated wall panels themselves are Factors that are prone to shrinkage, expansion, and uneven settlement cause structural deformation, which causes deformation stress in the prefabricated wall panels, resulting in cracks in the prefabricated wall panels, and finally leads to cracks in the prepared prefabricated wall panels, which makes the prefabricated wall panels The compressive strength is reduced

Abstract

The present invention relates to the technical field of wall panels, and discloses a preparation process for concrete prefabricated wall panels, including the following steps: S1: mold preparation; S2: installation of steel bars; installation of steel bars in the mold after S1 mold preparation; S3: pouring Concrete; pouring concrete towards the mold after S2 treatment; the raw materials of the concrete include by weight: 180-240 parts of cement, 550-630 parts of coarse aggregate, 100-150 parts of fine aggregate, 300 parts of fly ash ‑430 parts, 6‑15 parts of calcium lignosulfonate, 60‑80 parts of water, 20‑40 parts of fatty alcohol polyoxyethylene ether and 13‑37 parts of acrylamide grafted co-polymerized starch; S4: Vibration curing; S3 vibrating and curing the poured concrete; S5: dismantling the mold; S6: continuous curing; after the continuous curing in S6, the concrete prefabricated wall panel is obtained. The manufactured prefabricated wall panels can avoid cracks, thereby improving the compressive strength of the prefabricated wall panels.

Description

technical field [0001] The invention relates to the technical field of wallboards, more specifically, it relates to a preparation process of concrete prefabricated wallboards. Background technique [0002] With the increasingly fierce competition in science and technology, the country is gradually promoting the development of construction technology. In recent years, prefabricated technology has gradually emerged, so prefabricated wall panels, prefabricated columns, prefabricated stairs, prefabricated bridges, etc. have appeared. When making prefabricated parts, the staff pours concrete into the mold, then vibrates it evenly with a vibrator, and then maintains the prefabricated part at a certain temperature for a period of time to make the concrete form; finally, the mold is removed, to obtain prefabs. [0003] When preparing prefabricated wall panels, after the staff pours concrete into the mold, during the curing process of the prefabricated wall panels, the concrete is s...
