Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a simple pre-embedded bracket for connecting steel bars in structural columns. Background Technology

[0002] Currently, the connection of longitudinal reinforcement bars in structural columns in current building engineering generally adopts the post-installation method or the traditional pre-embedded steel bar method, both of which have significant defects.

[0003] Post-installation rebar requires drilling into the already poured wall, which leads to significant positioning deviations during actual construction. Drilling at the bottom of beams is also inconvenient, and working at heights poses safety risks. Traditional pre-embedded rebar methods face challenges such as needing to create openings in the formwork and high rebar offset rates during concrete pouring, requiring manual correction later. Exposed rebar also poses safety hazards in subsequent operations. These problems collectively lead to fluctuations in construction quality, delays in schedule, and increased costs.

[0004] To address the aforementioned issues, we propose a simplified pre-embedded support for connecting structural column reinforcement. Utility Model Content

[0005] The purpose of this utility model is to provide a simple pre-embedded bracket for connecting steel bars in structural columns, which aims to solve the technical problems in the prior art.

[0006] To achieve the above objectives, this utility model employs a simple pre-embedded support for connecting steel bars in structural columns, comprising several long horizontal skeletons, several short horizontal skeletons vertically arranged on one side of the long horizontal skeletons, several longitudinal skeletons vertically arranged on one side of the long horizontal skeletons and the short horizontal skeletons, the long horizontal skeletons, the short horizontal skeletons and the longitudinal skeletons forming a cuboid, and several EPS strips arranged on the side of the long horizontal skeletons and the short horizontal skeletons away from the longitudinal skeletons, and the EPS strips are arranged parallel to the longitudinal skeletons.

[0007] The upper outer surface of the EPS strip and the upper outer surface of the longitudinal frame are fixedly provided with an upper fixing frame, and the upper fixing frame has a hollow cavity inside.

[0008] The lower outer surface of the EPS strip and the lower outer surface of the longitudinal frame are fixedly provided with a lower fixing frame, and an extension protrusion is fixedly provided at the lower center of the lower fixing frame. A fixing positioning frame is provided on the outer surface of the extension protrusion.

[0009] The long horizontal frame, the short horizontal frame, and the longitudinal frame are all fixed with cable ties.

[0010] The EPS strip has the same length as the longitudinal frame.

[0011] The length of the short horizontal frame is two-thirds that of the long horizontal frame, and the length of the vertical frame is half that of the long horizontal frame.

[0012] The long horizontal frame, the short horizontal frame, and the longitudinal frame are all made of HPB300 material 6 mm diameter round steel. Beneficial effects

[0013] This utility model presents a simple pre-embedded support for connecting steel bars in structural columns. Through a cuboid frame structure and multiple fixing designs, it fundamentally solves the core problems of large positioning deviations and significant safety hazards inherent in traditional methods. Compared to the post-installation method, which is prone to positioning shifts when drilling into already poured walls, and the operational risks associated with drilling at high points under beams, the support uses prefabricated long and short horizontal and longitudinal frames assembled together. The rigidity of HPB300 round steel ensures the stability of the frame dimensions, and the use of cable ties forms a unified force-bearing system. During installation, precise positioning can be achieved directly using the upper and lower fixing frames—the extended protrusions of the lower fixing frame and the positioning frame ensure stable anchoring to the base layer, while the hollow cavity of the upper fixing frame reduces weight and ensures overall flatness, significantly reducing the error in the pre-embedded steel bar position. Simultaneously, the EPS strips are arranged parallel to the longitudinal frame and of uniform length, forming a protective barrier to prevent exposed steel bars. This solves the problems of exposed steel bars being easily shifted by collisions and causing safety accidents during subsequent operations, eliminating the need for manual correction later. This significantly improves the stability of construction quality, reduces the risk of schedule delays, and indirectly reduces rework costs.

[0014] This utility model presents a simplified pre-embedded support for connecting steel bars in structural columns. The modular design and adaptable material selection of the support significantly simplify construction procedures and reduce overall costs. Traditional post-installation of steel bars requires multiple processes such as drilling, hole cleaning, and adhesive injection; traditional pre-embedding requires opening holes in formwork and straightening after pouring, resulting in cumbersome procedures and high labor costs. This support, however, allows for prefabrication of the frame and rapid on-site assembly using cable ties. The integrated design of the upper and lower fixing frames eliminates complex positioning procedures, requiring no specialized drilling or formwork modification equipment. Ordinary construction workers can operate it after simple training, effectively improving labor efficiency. In terms of materials, it uses 6mm HPB300 round steel, combining rigidity and economy. Cable ties replace complex connection methods such as welding, reducing material waste. EPS strips are inexpensive and lightweight, highly compatible with the longitudinal frame, and require no custom-made special accessories. Furthermore, the stable support structure minimizes steel bar misalignment during concrete pouring, avoiding material waste and repeated labor input due to rework. Overall costs are optimized compared to traditional processes, making it particularly suitable for batch construction scenarios. Attached Figure Description

[0020] Please see Figures 1-3 , Figure 1 This is a structural schematic diagram of a simplified pre-embedded support for connecting steel bars in a structural column, according to this utility model. Figure 2 This is a front view of the simplified pre-embedded support for connecting steel bars in a structural column according to this utility model. Figure 3 This is a bottom view of the simplified pre-embedded support for connecting steel bars in a structural column according to this utility model. This utility model provides a simplified pre-embedded support for connecting steel bars in a structural column, including several long horizontal skeletons 1, several short horizontal skeletons 2 vertically arranged on one side of the several long horizontal skeletons 1, several longitudinal skeletons 3 vertically arranged on one side of the several long horizontal skeletons 1 and the several short horizontal skeletons 2, the several long horizontal skeletons 1, the short horizontal skeletons 2 and the several longitudinal skeletons 3 forming a cuboid, and several EPS strips 4 arranged on the side of the several long horizontal skeletons 1 and the several short horizontal skeletons 2 away from the longitudinal skeletons 3, and the EPS strips 4 are arranged parallel to the longitudinal skeletons 3.

[0021] In this embodiment, the cuboid prefabricated structure solves the core pain point of traditional process: compared with the drilling positioning deviation of the post-reinforcement method, the prefabricated skeleton is controlled by standardized dimensions; the rigidity of HPB300 round steel makes the skeleton less prone to deformation after forming, and together with the EPS strip 4, it forms a full-coverage protection, completely solving the problem of traditional pre-embedded steel bars being exposed and easily collided and shifted, saving the later correction process.

[0022] Furthermore, the upper outer surface of the EPS strip 4 and the upper outer surface of the longitudinal frame 3 are fixedly provided with the upper fixing frame 5, and the hollow cavity 6 is provided inside the upper fixing frame 5.

[0023] In this embodiment, the upper fixing frame 5 forms a uniform force-bearing surface, making the upper end of the frame uniformly stressed and avoiding local pressure deformation during pouring; the hollow cavity 6 not only reduces the weight of the support, but also provides a channel for concrete flow, ensuring the compactness of the pouring; compared with the design without a fixing frame, the positioning accuracy of the upper end is improved, and the hollow cavity 6 makes it easy for construction personnel to observe the internal pouring situation, reducing the risk of hollowing.

[0024] Furthermore, the lower outer surface of the EPS strip 4 and the lower outer surface of the longitudinal frame 3 are fixedly provided with the lower fixing frame 7, the lower center of the lower fixing frame 7 is fixedly provided with the extension protrusion 8, and the outer surface of the extension protrusion 8 is provided with the fixing positioning frame 9.

[0025] In this embodiment, the extended protrusion 8 and the fixed positioning frame 9 form a dual guarantee of "anchoring-positioning", which improves the connection strength between the support and the base layer and effectively solves the problem of high offset rate during the pouring of traditional pre-embedded steel bars, and the offset rate of the support is effectively controlled. The modular design of the fixed positioning frame 9 effectively shortens the on-site installation time and can be reused after disassembly, reducing the cost of consumables.

[0026] Furthermore, the long horizontal frame 1, the short horizontal frame 2, and the longitudinal frame 3 are all fixed using cable ties.

[0027] In this embodiment, cable ties replace traditional welding, eliminating the need for welding machine handling and wiring. Assembly can be completed by a single person, avoiding the impact of high welding temperatures on the steel's properties. Furthermore, cable ties have better corrosion resistance than welding points, extending the lifespan of the bracket. The binding process is reversible, and assembly errors can be adjusted at any time, making it particularly suitable for temporary on-site adjustments.

[0028] Furthermore, the EPS strip 4 has the same length as the longitudinal frame 3.

[0029] In this embodiment, the consistent length allows the EPS strip 4 to fully cover the outer side of the frame, avoiding the problem of localized exposed rebar caused by incomplete traditional protection; the flush upper and lower ends facilitate close contact with the upper fixing frame 5 and the lower fixing frame 7 to form a closed protection system, preventing concrete from seeping into the inner side of the frame during pouring and ensuring uniform thickness of the rebar protective layer; at the same time, it avoids uneven stress caused by length deviation, improving the overall stability of the support.

[0030] Furthermore, the length of the short horizontal frame 2 is two-thirds of the length of the long horizontal frame 1, and the length of the vertical frame 3 is half the length of the long horizontal frame 1.

[0031] In this embodiment, while meeting the adaptation requirements of common structural column sizes (such as 240mm×240mm, 370mm×370mm), the self-weight of the frame is reduced, and the bending strength still meets the construction requirements; the standardized size facilitates batch processing, improves processing efficiency, and different batches of brackets are interchangeable, reducing inventory management costs.

[0032] Furthermore, the long horizontal frame 1, the short horizontal frame 2, and the longitudinal frame 3 are all made of HPB300 material 6 mm diameter round steel.

[0033] In this embodiment, HPB300 round steel has a yield strength of ≥300MPa, which meets the requirements for support and positioning of the bracket. It also has excellent plasticity and is not easy to break during assembly. This material is a commonly used material in construction, which is convenient to purchase and has a stable price, making it suitable for large-scale promotion and use.

[0034] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
