Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, specifically to a tooling for positioning column reinforcement and leveling around the bottom of the column. Background Technology
[0002] Reinforcing bar positioning and column base leveling tools are widely used in construction engineering, especially before floor concrete pouring, to ensure accurate positioning of column reinforcing bars and flatness of the concrete around the column base. Current techniques typically rely on manual measurement and marking, supplemented by simple auxiliary tools such as wooden boards and steel plates for reinforcing bar positioning and concrete leveling. However, existing techniques have a series of problems that affect construction efficiency and project quality.
[0003] Existing techniques are cumbersome, with column reinforcement positioning and concrete leveling typically requiring manual labor. This not only increases construction complexity but is also susceptible to errors due to worker experience and skill level. Furthermore, existing tooling often requires multiple separate tools for both reinforcement positioning and concrete leveling, resulting in a large workload and low efficiency. This cumbersome process is particularly problematic in large-scale construction projects, severely impacting overall construction progress.
[0004] Furthermore, the design of existing tooling lacks multi-functional integration, typically requiring multiple separate tools for operation. It fails to effectively integrate rebar positioning and leveling functions into a single tool, increasing equipment usage and causing inconvenience during construction. Moreover, existing tooling is generally bulky and difficult to move, making it challenging for workers to quickly adjust and move it on-site, impacting operational flexibility and work efficiency. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a tooling for positioning column reinforcement and leveling around the bottom of the column. This tooling greatly simplifies the construction steps, improves construction efficiency, and effectively avoids the problems of inaccurate column reinforcement position or uneven concrete, thereby improving the overall project quality.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a tooling for positioning column reinforcement and leveling around the bottom of the column, including a leveling plate around the bottom of the column, a fixing plate and a column reinforcement positioning plate. The fixing plate is welded to the upper part of the leveling plate around the bottom of the column, and the column reinforcement positioning plate is welded to the fixing plate. The column reinforcement positioning plate is provided with multiple through holes, and fixing sleeves are provided on the through holes located at the four corners of the column reinforcement positioning plate. The fixing sleeves and through holes are fitted into the corresponding column reinforcement.
[0007] Furthermore, the flat plate around the base of the column is formed by welding two L-shaped steel plates together to form a square structure.
[0008] Furthermore, there are four fixing plates, which are welded to the four corners of the flat plate around the bottom of the column, and the column reinforcement positioning plate is laid flat on the four fixing plates.
[0009] Furthermore, the column reinforcement positioning plate is provided with 12 through holes.
[0010] Furthermore, the fixing sleeve is equipped with screws, and the column reinforcement is fixed by the screws after passing through the fixing sleeve.
[0011] Furthermore, the column reinforcement positioning plate is provided with two handles, which are located on opposite sides of the column reinforcement positioning plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The column reinforcement positioning function of this utility model is achieved through multiple through holes on the column reinforcement positioning plate. The precise design of the through holes ensures accurate alignment between the column reinforcement and the pre-embedded reinforcement in the floor slab. This design ensures the correct position of the column reinforcement, avoids the risk of column reinforcement shifting or misalignment during construction, and improves the stability and robustness of the overall structure.
[0014] The leveling function around the column base is achieved through the design of a leveling plate. This leveling plate, by adjusting its height and level before concrete pouring, ensures the surface of the concrete around the column is flat. This not only contributes to the flatness of the concrete at the column base after pouring but also provides the necessary sealing foundation for the subsequent installation of the column base sealing fixtures, ensuring the accuracy and sealing of the entire column base area.
[0015] By integrating the dual functions of column reinforcement positioning and column base leveling, this tooling greatly simplifies construction steps and improves construction efficiency. It also effectively avoids problems such as inaccurate column reinforcement positioning or uneven concrete, thus enhancing the overall project quality. This design not only saves construction time but also reduces human error, providing a solid foundation for subsequent engineering work. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0022] like Figures 1-3 As shown, this embodiment provides a fixture for positioning column reinforcement and leveling around the bottom of the column, including a column bottom leveling plate 1, a fixing plate 2, and a column reinforcement positioning plate 3. The fixing plate 2 is welded to the upper part of the column bottom leveling plate 1, and the column reinforcement positioning plate 3 is welded to the fixing plate 2. The column reinforcement positioning plate 3 is provided with multiple through holes 4. Fixing sleeves 5 are provided on the through holes 4 located at the four corners of the column reinforcement positioning plate 3. The fixing sleeves 5 and the through holes 4 are fitted together with the column reinforcement.
[0023] Firstly, the column reinforcement positioning function is achieved through multiple through holes 4 on the column reinforcement positioning plate 3. The precise design of the through holes 4 ensures accurate alignment between the column reinforcement and the pre-embedded reinforcement in the floor slab. This design ensures the correct position of the column reinforcement, avoids the risk of column reinforcement shifting or misalignment during construction, and improves the stability and robustness of the overall structure.
[0024] Secondly, the leveling function around the column base is achieved through the design of the column base leveling plate 1. Before concrete pouring, the column base leveling plate 1 can ensure the flatness of the concrete surface around the column by adjusting its height and level. This not only contributes to the flatness of the poured column base concrete but also provides the necessary sealing foundation for the subsequent installation of the column base sealing fixture, ensuring the accuracy and sealing of the entire column base area.
[0025] By integrating the dual functions of column reinforcement positioning and column base leveling, this tooling greatly simplifies construction steps, improves construction efficiency, and effectively avoids problems such as inaccurate column reinforcement positioning or uneven concrete, thus enhancing the overall project quality. This design not only saves construction time but also reduces human error, providing a solid foundation for subsequent engineering work.
[0026] In this embodiment, the leveling plate 1 around the column base is made of two L-shaped steel plates welded together to form a square structure, providing a solid and flat foundation and facilitating adjustment and ensuring the flatness of the concrete around the column base. This design ensures height adjustment during construction and improves the leveling effect of the concrete.
[0027] In this embodiment, there are four fixing plates 2, which are welded to the four corners of the column base leveling plate 1. The column reinforcement positioning plate 3 is laid flat on the four fixing plates 2, thereby ensuring a firm connection between the column reinforcement positioning plate 3 and the column base leveling plate 1. This structural design effectively avoids loosening or displacement during construction, ensuring the stability of the overall fixture.
[0028] In this embodiment, the column reinforcement positioning plate 3 is provided with 12 through holes 4, which can accurately fix the reinforcement in the designated position and ensure the accurate connection between the reinforcement and the pre-embedded reinforcement in the floor. The position of each through hole 4 is precisely designed so that the reinforcement will not shift during construction, thus ensuring the correct positioning of the column reinforcement.
[0029] In this embodiment, the fixing sleeve 5 is equipped with screws 6. After the column reinforcement passes through the fixing sleeve 5, it is fixed by the screws 6 to ensure that the column reinforcement will not move during construction. This design enhances the stability of the tooling, ensuring that the column reinforcement remains in the correct position during concrete pouring and preventing errors during construction.
[0030] In this embodiment, the column reinforcement positioning plate 3 is also equipped with two handles 7, which are respectively located on both sides of the column reinforcement positioning plate 3. Through these two handles 7, the tooling can be easily moved and its position adjusted, which greatly improves the ease of operation for construction personnel and reduces the time cost of handling and adjustment.
[0031] Specific implementation process: When in use, the tool is fitted with the corresponding column reinforcement through the through hole 4 and the fixing sleeve 5, and fixed with screws 6. During this process, the height and level of the leveling plate 1 around the bottom of the column can be adjusted. Then, the floor concrete is poured. After the concrete has solidified, the tool is removed and the subsequent column (such as precast column) construction can be carried out.
[0032] The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of this utility model should also be considered within the protection scope of this utility model.
