Description

Technical Field

[0001] The invention belongs to the technical field of assembled buildings, and in particular relates to an opening and closing mould for door and window hole plates. Background Art

[0002] In recent years, with the rapid development of my country's construction industry, prefabricated buildings have been vigorously promoted in my country due to their advantages of fast construction speed, energy saving and environmental protection, and controllable quality. As an important part of prefabricated buildings, the prefabrication and installation of prefabricated door and window openings are of great significance to improving construction efficiency and quality. Prefabricated door and window openings usually require the use of molds for prefabrication. This method requires pouring concrete into pre-supported molds, and then transporting them to the construction site for installation after curing under controlled conditions. However, the traditional formwork method has certain limitations. Workers are required to manually support the side molds and inner molds on the bottom molds of the door and window openings that match the shape of the door and window openings. The process is cumbersome and time-consuming, which greatly reduces the construction efficiency. After the concrete is poured, manual demolding is also time-consuming and labor-intensive, and it is easy to cause damage to the formwork and damage to the surface of the prefabricated parts.

[0003] In order to solve the above problems, Chinese utility model patent document CN 207757816 U discloses a universal combined door and window opening forming mold, which is formed by more than three side molds connected end to end in sequence, and any two adjacent side molds are connected by a corner mold, wherein the side mold includes a side mold panel and two side mold connecting plates respectively connected to the side mold panel at both ends along the enclosure direction thereof, and the corner mold includes a corner mold panel and two corner mold connecting plates respectively connected to the corner mold panel at both ends along the enclosure direction thereof. The utility model adopts a method of separating the side mold from the corner mold. When assembling the mold, the side mold is inserted from the top of the corner mold by cooperating with the lifting equipment, and then the side mold and the corner mold are connected by a detachable fastener to form a standardized prefabricated door and window opening mold. However, although the door and window opening forming mold simplifies the construction process to a certain extent and reduces the disassembly and assembly time to a certain extent, workers are still required to install or remove fasteners to form the door and window hole plate mold, and in this process, the side mold and the corner mold need to be lifted separately with the help of lifting equipment, which is not easy to operate and the effect of improving construction efficiency is not good.

[0004] Therefore, a door and window hole plate opening and closing mold is needed that can conveniently and quickly support and dismantle the mold and can effectively improve the construction efficiency. Summary of the invention
