Method for forming rough surface on side surface of precast concrete bay window

Abstract

The invention discloses a method for forming a rough surface on the side surface of a precast concrete bay window, and relates to the technical field of a precast concrete part. The method comprises the following steps of installing a plurality of equidistantly arranged rough surface forming assemblies on the inner side wall of each group of precast part forming templates; integrally assembling the four groups of precast part forming templates and the rough surface forming assemblies to form a forming mold of the precast concrete part; pouring concrete materials into the forming mold, and conducting curing and forming to form the precast concrete part; and removing the forming mold, so that the precast concrete part with the rough surface with grains on the surface can be obtained. According to the precast part obtained by using the forming method, the rough surface with the grains is formed on the surface of the precast part, the rough surface with a grain structure brought by the forming method not only plays a role of a rough surface, but also the formed precast concrete part is more attractive due to the grains, the method is suitable for forming precast concrete parts in various shapes, and the used formed bodies can also be recycled and reused.

Description

technical field [0001] The invention relates to the technical field of concrete prefabricated parts, in particular to a method for forming a rough surface on the side of a prefabricated concrete bay window. Background technique [0002] After searching, the Chinese patent discloses a molding die for the rough surface of prefabricated components and a method for making the rough surface (publication number CN110303572A). The technical content of this patent mainly includes the mold body; PE film, the PE film adhered to the mold A plurality of protrusions are provided on the inner wall of the body and on the side of the PE film away from the mold body. By adhering a PE film with multiple protrusions on the inner wall of the mold body, the rough surface is made. In terms of construction period, the use of PE film can save the rough surface construction process after the component is formed, shorten the processing and storage cycle of the component, and speed up the process.

AI Technical Summary

Problems solved by technology

[0006] 1. After the PE film is used, the waste PE film produced cannot be recycled and is difficult to decompose;

[0007] 2. PE film needs to be pasted before each molding, the process is complicated, and it is not suitable for members of the opposite sex;

[0008] 3. The PE film itself is made of plastic, and the sticking effect between the plastic and the steel mold is poor. During the production process, it may fall off and enter the component, affecting the quality of the component and affecting the effect of the rough surface

[0010] The grooves and bumps on the template must be obtained through integral molding during the template making process. This kind of template has low versatility. high production cost
