The purpose of reinforcement is to enhance the load-bearing capacity of the formwork, improve overall stability, and prevent the formwork from deformation or damage during the concrete pouring process. To this end, reinforcement materials such as steel pipes, steel bars and connectors are usually used, and technical means such as tie rod reinforcement, steel plate beam reinforcement and strengthening of joints are used to enhance the strength and stability of the formwork.

[0003] In the prior art, a Chinese patent application with publication number CN220150855U discloses that the utility model discloses a modular wood formwork reinforcement structure, comprising two relatively arranged spliced ​​formworks and a plurality of tension screws, a secondary back rib and a main back rib are sequentially arranged on the back of the spliced ​​formwork, the spliced ​​formwork comprises a plurality of wood formworks and a strip steel formwork connected between two adjacent wood formworks, the strip steel formwork is a spliced ​​strip steel formwork formed by sequentially connecting a plurality of steel formwork splicing sections, the steel formwork splicing section is a convex steel formwork with give way grooves on both sides, a plurality of positioning cards for fixing the secondary back ribs are arranged on the main back ribs, a plurality of screw through holes are arranged on each main back rib, a screw through hole is opened in the middle of the steel formwork splicing section.
