Description

Technical Field

[0001] This utility model belongs to the field of pier construction technology, specifically relating to a positioning device for the steel reinforcement cage of a square pier. Background Technology

[0002] Concrete square piers are widely used in building foundations, bridge engineering, port terminals, mechanical equipment installation, municipal engineering and other fields. They have strong load-bearing capacity, good stability, high durability and simple construction, and are a common foundation building component.

[0003] When subjected to bending moments, tensile forces, or requiring crack prevention, square piers must be reinforced with internal steel bars. Currently, most square pier reinforcement binding is done using string lines, while some are equipped with specialized tools, such as the reinforcement positioning clamp described in patent CN202220497705.9 for bridge square pier construction. This clamp uses slots on the inner edge of a frame-shaped positioning plate to quickly position the main reinforcement bars, improving the efficiency of reinforcement binding. However, these semi-circular slots cannot completely control the direction of the reinforcement bars, causing some bars to move inward or tilt, resulting in inaccurate reinforcement positioning, poor reinforcement alignment, and failure to meet the quality requirements of square piers. Utility Model Content

[0004] To address the aforementioned issues, this utility model discloses a square pier column rebar cage positioning device that bidirectionally clamps the rebar, preventing it from moving inward or outward towards the pier column, thus better controlling the linearity of the rebar. The device features a sophisticated structure, simple operation, easy control, and high rebar positioning accuracy.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A rectangular pier column rebar cage positioning device includes an outer limiting plate and an inner limiting plate. The outer limiting plate is a rectangular frame composed of several first auxiliary templates. Each first auxiliary template has multiple positioning slots 1 spaced apart on its inner edge. The inner limiting plate is movably mounted on the outer limiting plate. The inner limiting plate is a rectangular frame composed of several second auxiliary templates. Each second auxiliary template has multiple positioning slots 2 spaced apart on its outer edge. The positioning slots 1 and 2 are positioned correspondingly, and a gap is left between the positioning slots 1 and 2 to accommodate the rebar.

[0006] As an improvement of this utility model, the first auxiliary template includes a flat plate and end plates that are bent vertically on both sides. Multiple positioning slots are provided at intervals along the inner edge of the flat plate, and two adjacent first auxiliary templates are connected to the end plates by transverse bolts.

[0007] As an improvement of this utility model, the flat plate is provided with a first mounting hole, the second auxiliary template is provided with a second mounting hole, and the inner limiting plate is fixed to the outer limiting plate by longitudinal bolts.

[0008] As an improvement of this utility model, the second mounting hole is a waist-shaped hole.

[0009] As an improvement of this utility model, the positioning slot one and the positioning slot two are arc-shaped slots.

[0010] As an improvement of this utility model, a positioning post is fixed on the outer side of the outer limiting plate.

[0011] The beneficial effects of this utility model are as follows: This utility model discloses a rectangular pier column steel reinforcement cage positioning device, which uses an outer limiting plate and an inner limiting plate to bidirectionally clamp the steel reinforcement, preventing the steel reinforcement from moving to the inside or outside of the pier column. The steel reinforcement positioning accuracy is high, ensuring the quality requirements of the rectangular pier column. The structure is ingenious, the process is simple, and it is easy to operate and control, making it worthy of promotion. Attached Figure Description

[0017] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0018] As shown in the figure, the present invention provides a square pier column rebar cage positioning device, comprising an outer limiting plate 1 and an inner limiting plate 2. The outer limiting plate 1 is a square frame composed of 12 first auxiliary templates 3. Each first auxiliary template 3 has multiple positioning slots 4 spaced apart on its inner edge. The inner limiting plate 2 is movably mounted on the outer limiting plate 1. The inner limiting plate 2 is a square frame composed of 12 second auxiliary templates 5. Each second auxiliary template 5 has multiple positioning slots 6 spaced apart on its outer edge. The positioning slots 4 and 6 are positioned correspondingly, and a gap 7 for accommodating rebar is left between the positioning slots 4 and 6.

[0019] The present invention discloses a square pier column rebar cage positioning device, which is square in shape. The outer limiting plate 1 and the inner limiting plate 2 are used in combination. The outer limiting plate 1 is composed of 12 first auxiliary templates 3 connected to each other by transverse bolts 10. Each steel plate has an indefinite number of semi-circular positioning slots 4. The positioning slots 4 can fit with the outer radius of the rebar. The structure of the inner limiting plate 2 is basically similar to that of the outer limiting plate 1, except that the positioning slots 6 face outward and fit with the inner radius of the rebar. The number and position of the steel plate positioning slots are made according to the rebar arrangement of the pier column.

[0020] The outer limit plate 1 is fixed with a positioning post 13. When in use, the positioning post 13 is first welded to the steel cage to fix the 12 first auxiliary templates 3 to form a square circle. Then, the second auxiliary template 5 is fixed to the first auxiliary template 3 by longitudinal bolts 12. The positioning slot 1 4 and the positioning slot 2 6 are in corresponding positions. The steel bar is clamped in the gap 7 left between the positioning slot 1 4 and the positioning slot 2 6, which clamps the steel bar in both directions and restricts the movement or tilting of the steel bar.

[0021] The first auxiliary template 3 includes a flat plate 8 and two vertically bent end plates 9. Multiple positioning slots 4 are provided at intervals along the inner edge of the flat plate 8. Two adjacent first auxiliary templates 3 are connected to the end plates 9 by horizontal bolts 10.

[0022] The flat plate 8 of this utility model is provided with mounting hole 11, and the second auxiliary template 5 is provided with mounting hole 14. The inner limiting plate 2 is fixed to the outer limiting plate 1 by longitudinal bolts 12.

[0023] Mounting hole 2, number 14, can be a slotted hole, which can be used to fix steel bars of different diameters.

[0024] The present invention discloses a rectangular pier column steel reinforcement cage positioning device, which uses an outer limiting plate and an inner limiting plate to bidirectionally clamp the steel reinforcement, preventing the steel reinforcement from moving to the inside or outside of the pier column. The steel reinforcement positioning accuracy is high, ensuring the quality requirements of the rectangular pier column. The device has a compact structure, simple process, and is easy to operate and control, and is worthy of promotion.

[0025] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
