Description

Technical Field

[0001] This utility model relates to the field of ultra-high column formwork technology, specifically an ultra-high column formwork for concrete pouring. Background Technology

[0002] Traditional formwork concrete pouring techniques use steel formwork, which is assembled into components using flange connections and bolt tightening. A crane is then used to lift and assemble these components into a complete column formwork. However, due to the difficulty in separation and the need for hammering, deformation occurs, resulting in a short lifespan for steel formwork. It requires repair and adjustment, and can typically only be reused 5-7 times. Therefore, column construction using this technique often requires significant energy and manpower, resulting in high costs and low efficiency, and is unsuitable for the fast and efficient requirements of modern industry.

[0003] A search revealed Chinese patent application number 202322348348.7, which discloses a column formwork for concrete pouring. This patent relates to the field of concrete pouring technology, specifically a column formwork for concrete pouring. It includes multiple combined formworks, external clamps on the outside of the combined formworks, and a rebar support positioning mechanism on the top of the combined formworks. The cylindrical combined formworks can be stacked. The external clamps are located between the upper and lower cylindrical combined formworks. A power mechanism is installed at the center of the cross-shaped fixing bracket. This patent uses side stiffeners, external clamps, and stepped grooves to make the bottom combined formwork more firmly reinforced. The side stiffeners reinforce the combined formwork, further preventing cracking or deformation at the bottom due to concrete accumulation. The rebar support positioning mechanism ensures that the rebar support is centered during pouring, preventing the rebar support from shifting and causing instability.

[0004] Although the aforementioned patent can make the bottom of the combined formwork more robust by setting side stiffeners, external clamps, and stepped grooves, and the side stiffeners further reinforce the combined formwork to prevent cracking or deformation caused by concrete accumulation at the bottom, in actual use, the patent uses cylindrical combined formwork for layering. However, due to the limitation of the cylindrical shape of the combined formwork, it occupies a large area during transportation. The hollow parts of the combined formwork cannot be used reasonably, which means that workers can only move the cylindrical combined formwork in small batches at a time. This process is cumbersome, time-consuming, and labor-intensive, thus making it unsuitable for workers to use.

[0005] Therefore, it is necessary to modify the column formwork in the above-mentioned patent to effectively prevent the combined formwork from being limited by its cylindrical shape, which would cause it to occupy a large area during transportation and make it difficult for workers to move the cylindrical combined formwork in small batches at a time. This process is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0030] As a technical optimization of this utility model, the setting of the limiting cavity 13 and the limiting post 14 facilitates the installation of the template strip 4 and enables it to be limited, while also strengthening the connection effect between multiple template strips 4.

[0031] refer to Figure 2 , Figure 3 and Figure 4The embedded strip 3 is convex in shape and fits into the embedded groove 5.

[0032] As a technical optimization of this utility model, by setting the shape of the embedded strip 3 as a convex shape, the embedded strip 3 can be more securely engaged, thereby avoiding the problem of it sliding outward on its own.

[0033] refer to Figure 1 and Figure 2 The connecting strip 8 is L-shaped, and the interiors of the two symmetrical connecting strips 8 fit into the fastening strip 9.

[0034] As a technical optimization of this utility model, by setting the shape of the connecting strip 8 as L-shaped, the connecting strip 8 can fit the fastening strip 9 and the position of the fastening strip 9 can be positioned, thereby facilitating the installation of the fastening strip 9 by the staff.

[0035] refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The top of the connecting strip 8 has multiple fastening holes 15, which are evenly arranged. The top of the connecting strip 8 has multiple connecting holes 16, which correspond one-to-one with the fastening holes 15. The top of the fastening hole 15 is provided with a stud 17, and the other end of the stud 17 passes through the connecting hole 16 and is threaded with a nut 18.

[0036] As a technical optimization of this utility model, by setting the fastening hole 15, the connecting hole 16, the stud 17 and the nut 18, the connection effect between the connecting strip 8 and the fastening strip 9 can be further strengthened, and the fastening strip 9 can be prevented from sliding outward on its own.

[0037] refer to Figure 1 The lower fastening hole 15 has a reinforcing rib 19 inside, and the top of the reinforcing rib 19 extends to the upper fastening hole 15 and works in conjunction with it.

[0038] As a technical optimization of this utility model, by setting the reinforcing rib 19, the side of the reinforcing template block 2 can be reinforced, thereby improving the stability of the column template during use.

[0045] refer to Figure 1 , Figure 2 and Figure 4 The corners of template strip 4 are rounded.

[0046] As a technical optimization of this utility model, the corners of the template strip 4 are rounded, which can distribute the pressure at the top to both sides and form a self-supporting state. This design is not only aesthetically pleasing, but more importantly, it can effectively disperse gravity and improve the overall stability.

[0047] The working principle and usage process of this utility model are as follows: When using this column template, first, install the mounting base 1 to the designated position, then install the four limiting posts 14 at the four corners of the top of the mounting base 1, and then insert the limiting cavities 13 on the four template strips 4 from top to bottom along the four limiting posts 14, so that they are respectively installed on the mounting base 1. Next, insert the embedding strips 3 on the four template blocks 2 into the embedding grooves 5 of the template strips 4, and so on. Insert the sealing strips 7 on the other four template strips 4 into the sealing grooves 6 on the lower template strip 4, and align the sealing strips 7 on the other four template blocks 2 with the sealing grooves 6 on the lower template block 2, so that the embedding strips 3 and the embedding grooves 5 are engaged. At this time, the upper and lower template blocks 2 are stacked on each other, and the two connecting strips 8 are aligned with each other. Then, place the fastening strip 9 into the two connecting strips 8, and similarly place the other three fastening strips 9 into the connecting strips 8. Use the four sleeves 11 to interlock the four fastening strips 9 end to end, and then fix them with the fixing bolts 12. Then, pass the studs 17 through the fastening holes 15 and the connecting holes 16 respectively, and then fix the other end of the studs 17 with the nuts 18. This can fix the position of the fastening strips 9, thereby achieving the effect of reinforcing the connection between the upper and lower template blocks 2. Repeat the above work several times to assemble an ultra-high column template. At this time, the side of the column template can be reinforced by installing reinforcing ribs 19 in the fastening holes 15. Then, pour the concrete into the column template composed of template blocks 2 and template strips 4.
