Description

Technical Field

[0001] The present invention relates to the field of assembled buildings, in particular to a mold and a processing method for door and window opening plates, which are used for assembled buildings and building renovation. Background Art

[0002] Most portal wall panels utilize an on-site assembled frame structure using masonry blocks. These assembled portal walls present several challenges during installation and use. First, on-site assembly of portals is time-consuming, labor-intensive, slow, and costly. Second, on-site assembly results vary between workers, making precision difficult to guarantee. Furthermore, gaps inevitably remain after assembly, leading to the common problem of cracks during subsequent use. Therefore, we have developed a prefabricated, integral portal wall panel for construction and have applied for and obtained a utility model patent (CN219638236U) and an appearance patent. However, the panel is difficult to manufacture and its strength is difficult to guarantee. Specific molds and process methods are required to maximize the product's advantages.
