DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiment of the present application more clear, the technical scheme in the embodiment of the present application will be described clearly and completely below with reference to the drawings in the embodiment of the present application. Obviously, the described embodiment is a part of the embodiment of the present application, not all the embodiments. Based on the embodiment in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0026] The embodiment of the present application provides a positioning support for a post-anchoring structure assembly formwork, which can solve the problem that the positioning support is integrated and not easy to efficiently remove after the pouring of the post-anchoring structure is completed in the prior art.

[0027] In the prior art, new size and new specification supports are usually used for formwork pouring when dealing with different sizes of stepped post-anchoring structures. These supports usually adopt an integrated structure. Although this method ensures the safety of the structure, it also increases the cost of the temporary construction. At the same time, once the anchoring pouring is completed, the removal of the support and the formwork is also quite difficult. Therefore, the integrated support structure is reasonably split. In the embodiment, the support is divided into adaptive supports located at the top and the bottom according to the different inclination degrees of the stepped post-anchoring structure, which is mainly used to adapt to different stepped post-anchoring structures. The individual supports erected on each layer of post-anchoring steps are arranged by a plurality of units and are detachably connected. The units and the adaptive supports located at the top and the bottom are also detachably connected, thereby solving the problem that the positioning support is integrated and not easy to efficiently remove after the pouring of the post-anchoring structure is completed in the prior art.

[0029] Through this design, the assembly support 1 is the main frame of the entire support system, which is modular in structure design, facilitating assembly and disassembly. The support unit 2 is the basic component of the support system, and a plurality of support units 2 are connected to each other through the connecting assembly 5 to form the assembly support. The connecting assembly 5 is designed to be detachable, and is connected or disassembled between the support units 2 in the form of lock, plug-in or bolt, etc. The connecting assembly 5 ensures the firmness of the connection while allowing quick disassembly to improve construction efficiency. The top support 8 and the bottom support 7 adapt to different construction environments and the inclined surface of the stepped post anchor structure, ensuring the accuracy and stability of the formwork positioning.

[0030] In some preferred embodiments, the number of progressive inclined structures is multiple; the multiple progressive inclined structures are distributed along the length direction of the post anchor structure; and the multiple progressive inclined structures are fixedly connected through a flat link 11. Through this structural design, the multiple progressive inclined structures fixedly connected at intervals through the flat link 11 can effectively disperse the load and ensure the stability of the support when bearing. This design provides better stress performance. It reduces the safety hazards caused by loose connection parts, providing more reliable protection for workers during construction.

[0031] In some preferred embodiments, a plurality of fixed assemblies are provided on the post anchor structure of each step of the to-be-poured section along the length direction, for fixing the progressive inclined structure, the bottom support 7 and the top support 8; and the fixed assemblies are detachably connected with the progressive inclined structure, the bottom support 7 and the top support 8. The design of this scheme, i.e. the detachable connection of each component of the assembly support 1, the support unit 2, the bottom support 7 and the top support 8 with the fixed assemblies on the corresponding stepped post anchor structure, detachably fixes the assembly support 1 on the anchor step, improving the stability of subsequent construction. An efficient and safe post anchor structure support system is constructed.
