Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, specifically an adjustable column formwork device. Background Technology
[0002] Currently, with the rapid development of our country, the acceleration of urbanization, and the booming development of the construction industry, wooden formwork wall and column shaping is often used in the construction process to improve the construction quality. Among them, the shaping of wooden formwork wall and column requires the installation of reinforcing profiles around the sides of the wooden formwork wall and column.
[0003] In current practice, to reinforce wooden formwork for walls, traditional methods such as step-by-step tightening or staggered connection of horizontal double steel pipes are often used. The former relies on subjective reinforcement and locking, which poses significant quality and safety risks. The latter achieves reinforcement and locking by using a limiting groove to abut against the groove wall of the horizontal double steel pipe, which is more cumbersome, requires more tools, and incurs higher costs during construction.
[0004] To address this, we propose an adjustable column formwork device. Utility Model Content
[0005] To address the problems mentioned in the background art, this utility model provides an adjustable column template device, which has the advantages of adjusting the reinforcement size according to the column size during use, using staggered reinforcement, but being simple to operate, having a high component reuse rate, and saving costs.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable column template device, including a fixed rod, a fixed bolt passing through the top end of the fixed rod, an adjustable rod slidably provided at the top end of the fixed rod, and a groove opened at the top end of the adjustable rod, with the fixed bolt sliding inside the groove.
[0007] Preferably, a connecting hook is fixedly provided on one bottom end of the fixing bolt, and the connecting hook is U-shaped.
[0008] Preferably, a matching wooden block is attached to the outer side of the fixing rod, and a template is fixed to the other side of the matching wooden block.
[0009] Preferably, both the fixed rod and the adjustable rod are made of aluminum alloy, which has high strength, light weight, and is easy to clean and prevents rust.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model, by setting fixed rods and adjustable rods, allows the reinforcement size to be adjusted according to the column size during use. It also adopts staggered reinforcement, but the operation is simple, the components have a high reuse rate, and the cost is saved. All clamp components are made of aluminum alloy, which is high in strength, light in weight, easy to clean and rust-proof, simple to construct, and has a high safety factor.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] like Figures 1 to 5 As shown, this utility model provides an adjustable column template device, including a fixed rod 1, a fixed bolt 2 passing through the top of the fixed rod 1, an adjustable rod 4 slidingly provided at the top of the fixed rod 1, a groove 3 opened at the top of the adjustable rod 4, and the fixed bolt 2 sliding inside the groove 3, the nut at the top of the fixed bolt 2 is tightened, and the bottom end of the nut fits against the top end of the groove 3.
[0020] Specifically, a connecting hook 5 is fixedly provided on one bottom side of the fixing bolt 2, and the connecting hook 5 is U-shaped. The connecting hook 5 is used for snap-fit connection.
[0021] Furthermore, a matching wooden block 6 is attached to the outer side of the fixing rod 1, and a template 7 is fixed on the other side of the matching wooden block 6. The fixing rod 1 is used to fix the matching wooden block 6.
