Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a column steel cage anti-tipping structure. Background Technology

[0002] In subway station construction, reinforced concrete columns are key load-bearing structures, and their construction quality and safety play a decisive role in the stability of the entire subway station. Currently, the conventional construction process for reinforced concrete columns in subway stations generally involves batch processing of the column reinforcement cages, followed by unified hoisting and concrete pouring.

[0003] Specifically, the construction team will mass-produce the column reinforcement cages in a dedicated processing area according to the design drawings and construction specifications. Once all the column reinforcement cages are processed, large lifting equipment, such as tower cranes or truck cranes, will be used to sequentially lift each cage to its corresponding installation location. During the lifting process, close cooperation between professional signalmen and crane operators is required to precisely control the lifting, rotation, and lowering speeds of the reinforcement cages to ensure accurate positioning. After the reinforcement cages are in place, construction workers will use temporary supports and welding to secure them in their designated positions, preventing displacement during subsequent construction. Finally, after all the column reinforcement cages are secured, a unified concrete pouring operation will be carried out. The mixed concrete will be injected into the reinforcement cages using a concrete pump, and after vibration compaction, the reinforced concrete columns will be formed.

[0004] However, this traditional construction method faces numerous challenges in practical application. Subway stations typically have multi-story structures, with each floor being quite tall, leading to an increase in the height of the reinforced concrete columns and their internal steel cages. As the height of the steel cage increases, its center of gravity also rises, significantly reducing its stability during hoisting and fixing. Specifically, once the steel cage is hoisted to its installation position and initially fixed, its high center of gravity makes it highly susceptible to tipping over even with minor external forces, such as contact from construction workers, wind, or slight swaying of the crane. A tipping steel cage can trigger a series of serious consequences, including injuring on-site workers, damaging surrounding construction equipment and temporary facilities, disrupting the overall construction progress of the subway station, and preventing the project from being delivered on schedule.

[0005] Therefore, how to solve the problem of steel cages easily tipping over due to increased height during the construction of reinforced concrete columns in subway stations has become a key technical challenge that urgently needs to be addressed in the current construction field. Utility Model Content

[0006] In order to overcome the problem that the steel cages in the existing reinforced concrete columns of subway stations are prone to tipping over due to the increase in height, this utility model provides a column steel cage anti-tipping structure.

[0007] The technical solution of this utility model is as follows:

[0008] A column reinforcement cage anti-tipping structure includes a column reinforcement cage, a foundation reinforcement bar set on the lower periphery of the column reinforcement cage, and pile head reinforcement bars set at both ends of the bottom of the foundation reinforcement bar. The foundation reinforcement bar is welded and fixed to the column reinforcement cage and the pile head reinforcement bars respectively. A guy rope is connected to each of the four corners of the top of the column reinforcement cage. The other ends of the four guy ropes are respectively connected to four counterweights. The four counterweights are respectively set at the four corners of the foundation reinforcement bar.

[0009] As a preferred embodiment of this utility model, the foundation reinforcement includes upper reinforcement and lower reinforcement. The upper reinforcement is welded and fixed to the main reinforcement at the four corners of the column reinforcement cage, and the lower reinforcement is welded and fixed to the column reinforcement cage and the pile head reinforcement of the cast-in-place pile, respectively.

[0010] As a preferred embodiment of this utility model, the upper layer of reinforcing bars is welded and fixed to the main reinforcing bars at the four corners of the column reinforcing cage via L-shaped connecting conductors, and the lower layer of reinforcing bars is welded and fixed to the column reinforcing cage and the pile head reinforcing bars via L-shaped connecting conductors respectively.

[0011] In a preferred embodiment of this utility model, the L-shaped connecting conductor is a steel bar or a round steel bar.

[0012] As a preferred embodiment of this utility model, the foundation reinforcement includes a lower layer of reinforcement, which is welded and fixed to the column reinforcement cage and the pile head reinforcement of the cast-in-place pile, respectively. The main reinforcement bars at the four corners of the column reinforcement cage are also welded and fixed to the lower layer of reinforcement by reinforcing diagonal reinforcement bars.

[0013] As a preferred embodiment of this utility model, the counterweight is a concrete anchor block.

[0014] As a preferred embodiment of this utility model, the guy rope is anchored to the top surface of the counterweight block by a round steel ground anchor.

[0015] As a preferred embodiment of this utility model, the weight of the counterweight is not less than 3 tons.

[0017] In a preferred embodiment of this utility model, the angle between the guy rope and the ground is 60°.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The anti-tipping structure for the steel cage of the column provided by this utility model effectively solves the problem of the steel cage easily tipping over due to the increase in height during the construction of reinforced concrete columns in subway stations through the coordinated action of components such as the foundation steel reinforcement, the pile head steel reinforcement, the guy rope and the counterweight. This improves the safety of the construction process, ensures the construction progress, reduces the risk of accidents such as personnel injury and equipment damage that may be caused by the tipping of the steel cage, and at the same time reduces the delay in construction period and economic losses caused by accident handling.

[0027] Please see Figure 1 This utility model provides an anti-tipping structure for a column reinforcement cage 1, including a column reinforcement cage 1, a foundation reinforcement 2 set on the lower periphery of the column reinforcement cage 1, and pile head reinforcement 3 set at both ends of the bottom of the foundation reinforcement 2. The foundation reinforcement 2 is welded and fixed to the column reinforcement cage 1 and the pile head reinforcement 3 respectively. A guy rope 4 is connected to each of the four corners of the top of the column reinforcement cage 1. The other end of the four guy ropes 4 is connected to four counterweights 5 respectively. The four counterweights 5 are respectively set at the four corners of the periphery of the foundation reinforcement 2.

[0028] In this embodiment, by placing the foundation reinforcement 2 on the lower periphery of the column reinforcement cage 1 and welding it to the column reinforcement cage 1 and the pile head reinforcement 3 respectively, the column reinforcement cage 1, foundation reinforcement 2, and pile head reinforcement 3 form an organic whole, increasing the integrity and stability of the structure. The pile head reinforcement 3, as the foundation of the entire anti-tipping structure of the column reinforcement cage 1, provides a solid foundation support for the entire structure. Buried underground, the pile head reinforcement 3 has high strength and stability, capable of withstanding the huge load transmitted from the column reinforcement cage 1 and transferring the load to the surrounding foundation soil, providing a reliable supporting foundation for the column reinforcement cage 1. This fundamentally ensures the stability of the column reinforcement cage 1 and prevents it from tipping over due to uneven foundation settlement or external forces. By setting four counterweights 5 at the four corners of the outer perimeter of the foundation reinforcement 2, and connecting the top four corners of the column reinforcement cage 1 to the four counterweights 5 via guy ropes 4, the four guy ropes 4 apply tension to the column reinforcement cage 1 from different directions, forming a lateral restraint system. When the column reinforcement cage 1 is subjected to lateral forces (such as wind force, collisions with construction workers, etc.), the guy ropes 4 can effectively limit the lateral displacement of the column reinforcement cage 1, preventing it from tilting or falling over. The length of the guy ropes 4 can be adjusted according to actual conditions. By adjusting the tension of the four guy ropes 4, the column reinforcement cage 1 can be kept vertical during construction, ensuring its center of gravity stability. Even if some uneven loads or external interference occur during construction, the balance of the column reinforcement cage 1 can be restored by timely adjustment of the tension of the guy ropes 4, further improving its stability.

[0029] Please see Figure 1 In one embodiment, the foundation reinforcement 2 includes upper reinforcement 21 and lower reinforcement 22. The upper reinforcement 21 is welded and fixed to the main reinforcement bars at the four corners of the column reinforcement cage 1, and the lower reinforcement 22 is welded and fixed to the column reinforcement cage 1 and the pile head reinforcement 3 of the cast-in-place pile, forming a three-dimensional constraint frame. The upper reinforcement 21 can restrict the displacement of the upper part of the column reinforcement cage 1, while the lower reinforcement 22 can ensure the reliable connection between the bottom of the column reinforcement cage 1 and the foundation, preventing it from shifting due to the action of concrete during the pouring process, ensuring the verticality and positional accuracy of the column reinforcement cage 1, thereby ensuring the construction quality of the subsequent column. At the same time, the double-layer reinforcement structure of the foundation reinforcement 2 can more evenly transfer the load of the column reinforcement cage 1 to the foundation and the cast-in-place pile.

[0030] Furthermore, in one embodiment, the upper reinforcing bars 21 are welded and fixed to the main reinforcing bars at the four corners of the column reinforcing cage 1 via L-shaped connecting conductors, and the lower reinforcing bars 22 are welded and fixed to the column reinforcing cage 1 and the pile head reinforcing bars 3 of the cast-in-place piles via L-shaped connecting conductors respectively. The L-shaped connecting conductors are made of reinforcing steel bars or round steel. The use of L-shaped connecting conductors increases the contact area and weld length at the connection points. Compared with direct welding, L-shaped connecting conductors make the weld more robust, reducing the risk of loosening or breakage due to weak welding. The L-shaped connecting conductors made of reinforcing steel bars or round steel bars have high strength and toughness, enabling them to better withstand the load transmitted from the column reinforcing cage 1, ensuring the reliability of the connection, and further enhancing the stability of the entire anti-tipping structure.

[0031] Please see Figure 2 In another embodiment, the foundation reinforcement 2 may consist only of the lower layer reinforcement 22, which is welded and fixed to the column reinforcement cage 1 and the pile head reinforcement 3 of the cast-in-place piles. The main reinforcement bars at the four corners of the column reinforcement cage 1 are also welded and fixed to the lower layer reinforcement 22 by reinforcing diagonal reinforcement bars 6. The structure of the foundation reinforcement 2 using only the lower layer reinforcement 22 is simpler than the double-layer reinforcement structure, reducing the amount of reinforcement used and construction procedures, and lowering material and construction costs. At the same time, the simplified structure facilitates construction management and quality control, reducing construction quality problems that may occur due to structural complexity. In addition, although the upper layer reinforcement 21 is omitted, the main reinforcement bars at the four corners of the column reinforcement cage 1 are welded and fixed to the lower layer reinforcement 22 by the reinforcing diagonal reinforcement bars 6, forming a stable triangular structure. Triangles have the characteristic of strong stability, and the reinforcing diagonal reinforcement bars 6 can effectively resist the horizontal displacement and overturning moment of the column reinforcement cage 1, preventing the column reinforcement cage 1 from shifting during the pouring of the foundation.

[0032] In one embodiment, the counterweight 5 is a concrete anchor block, and the guy rope 4 is anchored to the top surface of the counterweight 5 via a round steel ground anchor. The concrete anchor block has high strength and stability, providing reliable reaction support for the guy rope 4. Its large volume and mass ensure that it is not easily moved or overturned when subjected to the tension of the guy rope 4, thus ensuring the anchoring effect of the guy rope 4. The combined use of the round steel ground anchor and the concrete anchor block further enhances the reliability of the anchoring. The round steel ground anchor can penetrate deep into the concrete, effectively transferring the tension of the guy rope 4 to the concrete anchor block through the adhesion and friction with the concrete, thereby improving the load-bearing capacity of the entire anchoring system.

[0033] In one embodiment, the counterweight 5 weighs no less than 3 tons. This substantial weight provides sufficient reaction force to balance various overturning moments that the steel reinforcement cage 1 may experience during construction, such as wind force and the impact of concrete pouring. It should be noted that the counterweight 5 can be selected in different weights and specifications according to actual needs, and its installation and position can be easily adjusted. If the stability of the steel reinforcement cage 1 is found to be insufficient during construction, the tension of the guy ropes 4 can be increased by adding the weight of the counterweight 5 or adjusting its position, thereby improving the anti-tipping ability of the steel reinforcement cage 1. Simultaneously, the placement of the counterweight 5 will not significantly interfere with the construction process, facilitating other operations for construction personnel, and it can be reused.

[0034] In one embodiment, the angle between the guy rope 4 and the ground is between 50° and 70°. When the angle between the guy rope 4 and the ground is between 50° and 70°, the tension of the guy rope 4 can be more effectively decomposed into horizontal and vertical components, thereby better balancing the overturning moment of the column reinforcement cage 1 and bearing its own weight. Among them, when the angle is 60°, the tension decomposition effect reaches a better state, which can ensure that the guy rope 4 provides sufficient horizontal tension to prevent the column reinforcement cage 1 from tilting, while reasonably distributing the vertical load, reducing the stress concentration of the guy rope 4, and improving the service life and safety of the guy rope 4.

[0035] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.

[0036] The present utility model patent has been described above with reference to the accompanying drawings.

Any improvements made by adopting the inventive concept and technical solution of the present utility model patent, or the direct application of the inventive concept and technical solution of the present utility model patent to other occasions without modification, are all within the protection scope of the present utility model.
