Formwork is a tool used to support and shape concrete structures in construction. The formwork is installed at the bottom of the prefabricated composite panel as a temporary support structure during the construction phase.

The end of the longitudinal steel bar 205 away from the connecting plate 203 is plugged into the guide groove 206. The transverse steel bar 209 is welded to the longitudinal steel bar 205 to form a steel bar skeleton, which improves the overall rigidity and bending resistance of the composite plate. The welding design ensures that the force transmission between the steel bars is more efficient and improves the load-bearing capacity of the plate under horizontal and vertical loads. The uniform distribution of the transverse steel bars provides support for the subsequent concrete pouring, helps to evenly distribute the concrete, and avoids deformation of the plate.

[0022] See also Figure 6-Figure 8The inner wall of the composite plate body 1 is provided with a plurality of transverse steel bars 209, which are welded to the longitudinal steel bars 205. The transverse steel bars 209 and the longitudinal steel bars 205 are welded to form a steel skeleton, which improves the overall rigidity and bending resistance of the composite plate.

After the composite plate body 1 is formed, the mold is removed; a steel skeleton is formed by binding and welding the longitudinal steel bars and the transverse steel bars, so that the composite plate has higher bending, shear and compression resistance, ensuring the mechanical properties and stability of the overall structure. The reinforcing mechanism composed of the reinforcing rib 301, the steel bar connecting frame 302 and the reinforcement frame 303 effectively improves the bearing capacity and deformation resistance of the composite plate and adapts to complex load environments. A groove 8 is reserved at the top of the composite plate body 1 to provide positioning for steel bar docking and concrete pouring, simplify the splicing process, and improve construction efficiency.

[0035] S6, pouring: injecting concrete slurry into the connection part through the grouting groove 202, and the slurry flows into the slurry storage groove 204. After the concrete solidifies, the connection strength between the adjacent composite board bodies 1 is further enhanced. After the composite board bodies 1 are installed and connected and reinforced, subsequent construction processes such as concrete pouring are carried out to form a complete building structure; The synergistic effect of the grouting groove 202 and the grout storage groove 204 ensures that the concrete slurry is evenly filled and solidified at the connection part, making the splicing between the composite plates tighter and stronger. This process not only improves the strength and density of the connection part, but also speeds up the construction progress, providing a reliable guarantee for forming a complete and high-strength building structure.

[0036] S7. Disassemble the template 4: Use a wrench or other tool to unscrew the bolt 5 that fixes the template 4 and the composite plate body 1, and keep the bolt 5 properly for subsequent reuse. When tightening the bolt 5, pay attention to using moderate force, turn the handle 603 of the locking mechanism 6, drive the bidirectional threaded rod 602 to rotate in the opposite direction, and make the moving block 604 move away from the fixed shell 606 under the limiting action of the limiting assembly, so that the clamping rod 605 is pulled out of the inner groove of the fixed shell 606, and the locking connection of the adjacent composite plates at the bottom of the template 4 is released. After releasing the connection between the locking mechanism 6 and the bolt 5, you can use a crowbar or other tool to gently pry the template 4 so that the template 4 is gradually separated from the composite plate body 1. When prying, pay attention to applying force evenly to avoid damage to the composite plate body 1.

[0037] The process of disassembling the formwork 4 achieves rapid and convenient disassembly of the formwork 4 through reasonable use of tools and precise operating steps, and ensures that the structure of the composite plate and the formwork 4 is not damaged, providing guarantees for the reuse of the formwork 4 and improving construction efficiency. It also embodies environmental protection and economy, and is suitable for the efficient construction needs of modern prefabricated buildings.
