Description

Technical Field

[0002] Mass concrete plays a vital role in modern construction engineering. It refers to large-volume concrete structures with a minimum geometric dimension of one meter. These structures are expected to develop harmful cracks due to temperature changes and shrinkage caused by the hydration of cementitious materials. Mass concrete formwork is a key tool for pouring and shaping such structures. Its main function is to provide a stable space for the concrete that meets the design shape and size requirements. During the concrete pouring process, it bears the self-weight of the concrete, lateral pressure, and various loads during construction, ensuring that the concrete maintains the expected structural form during the setting and hardening process. The quality and performance of mass concrete formwork directly affect the structural safety and durability of the entire project.

[0003] A search revealed Chinese Patent Publication No. CN221741985U, which discloses a concrete building formwork, belonging to the field of building formwork technology. It includes a load-bearing base plate, a concrete building formwork body, a first assembly component, and a second assembly component. The load-bearing base plate is rotatably connected to the concrete building formwork body. A mounting groove is provided on the top of the load-bearing base plate, and a first connector is fixedly connected to the inner wall of the mounting groove. An electric support rod is rotatably connected to the first connector. L-shaped connectors are fixedly connected to both sides of the first assembly component, and a first locking strip is fixedly connected to each of the two L-shaped connectors. Second locking strips are fixedly connected to both ends of the second assembly component. The concrete building formwork body has an assembly groove. This utility model allows for adjustment of the support angle as needed and can be tightly spliced ​​for pouring large-volume concrete components, thereby improving applicability and facilitating folding and storage to reduce space requirements during transport. However, the above structure does not consider the speed of assembly, cannot adjust the size, and the support method is not flexible enough, requiring additional space and failing to meet usage needs.
