Technical Field

[0001] The utility model relates to the technical field of concrete formwork, in particular to a quick-detachable formwork frame for a building concrete structure. Background Art

[0002] Concrete structure formwork refers to a complete set of structural systems for the newly poured concrete forming formwork and the supporting formwork. The detachable formwork is a type of supporting formwork. The detachable formwork also includes a general detachable formwork, that is, the ready-made formwork, and the other is the fixed formwork. This formwork is a formwork plate of various specifications produced by the factory, which is installed by a fixture and a supporting system. When the formwork is in use, there is a matching frame on the outside, and then the building concrete structure quick-detachable formwork frame will be used;

[0003] In a support formwork for a reinforced concrete frame disclosed in publication number CN218881560U, when it is necessary to demould the support formwork on both sides of the reinforced concrete frame, the support plate assemblies on both sides of the reinforced concrete frame are no longer connected to each other by removing the connecting piece, and then the locking assembly on the second connecting frame is used to make the second connecting frame no longer restrict the sliding of the insertion plate, so that the insertion plate in each first connecting frame can slide out from the second connecting frame corresponding thereto, and after the insertion plate is slid out of the second connecting frame, the second support plate is slid upward along the side wall of the first support plate, so that the first support plate and the second support plate can be separated from each other, thereby achieving the effect of quickly demoulding the support plate assemblies on both sides of the frame structure, and by using the connecting mechanism and the second support plate sliding along the side wall of the first support plate, the second support plate can be quickly detached from the first support plate, which not only improves the work efficiency of the staff in demoulding the support formwork to a certain extent, but also enables the support formwork to be recycled for multiple times;

[0004] However, the above scheme still has the following problems during use: when in use, it is connected and assembled by connecting multiple plug-in plates, support plates and other components, which makes the operation cumbersome and laborious to disassemble and assemble, and the fixing direction of the connection is consistent with the docking direction. When an external force is applied along the installation direction, the stability of the connection will be affected.

[0005] Therefore, we propose a quick-disassembly formwork frame for building concrete structure to solve the problems raised above. Utility Model Content
