Description

Technical Field

[0001] This utility model belongs to the field of steel cage internal support technology, and more specifically, it relates to an adjustable steel cage internal support structure. Background Technology

[0002] In the fabrication of steel cages for building construction, in order to ensure the shape stability of the steel cage and to withstand external forces and maintain structural integrity during subsequent processes such as concrete pouring, construction workers often use internal bracing structures for the steel cage.

[0003] However, traditional devices do not have the function of adjusting the size of the binding holes. As a result, in actual construction, due to the variety of specifications (such as diameter and length) of the steel cages, the traditional internal support structure cannot be well adapted to steel cages of different sizes, and the steel cages may experience insufficient or excessive support.

[0004] During concrete pouring, the lateral pressure and other external forces can easily cause the reinforcing cage to deform, making it unable to meet the requirements. This not only affects the overall quality of the building structure and reduces its load-bearing capacity, but also increases construction costs and time due to rework or reinforcement, thus affecting the progress and economic benefits of the entire project. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an adjustable steel cage internal support structure to solve the technical problem that traditional devices in the prior art do not have the function of adjusting the size of the binding holes.

[0006] The purpose and function of this utility model's adjustable steel cage internal support structure are achieved through the following specific technical means: An adjustable steel cage internal support structure includes multiple sets of first steel bars and two sets of connecting discs. Multiple sets of first through holes are formed on each of the two sets of connecting discs, through which the multiple sets of first steel bars pass. A second through hole is formed in the center of each of the two sets of connecting discs, and the two sets of connecting discs are connected by a bearing connecting shaft passing through the second through hole. Fixed connecting blocks for adjusting the distance between the multiple sets of first steel bars are provided on both sides of each of the two sets of connecting discs. Multiple sets of bidirectional support columns are provided between the two sets of connecting discs, and each end of the multiple sets of bidirectional support columns has an extended support arm. Multiple sets of second steel bars and multiple sets of fixing rings for auxiliary fixing are provided between the two sets of connecting discs, and the multiple sets of fixing rings are all located between the two sets of bidirectional support columns.

[0007] According to a preferred embodiment, multiple sets of first perforations are arranged at equal intervals along the diameter of the connecting disc, and the positions of multiple sets of first perforations decrease sequentially from the outside to the inside along the radius of the connecting disc. When the diameter of the binding steel bar is reduced, multiple sets of first steel bars are inserted into the corresponding first perforations.

[0008] According to a preferred embodiment, each of the multiple sets of first reinforcing bars has two sets of threaded lines at both ends, and the two sets of connecting discs are located between the two sets of threaded lines, and the two sets of connecting discs are connected to the multiple sets of first reinforcing bars by multiple sets of bolts.

[0009] According to a preferred embodiment, multiple sets of connecting cylinders are provided on multiple sets of the first reinforcing bars, and the connecting cylinders in two sets are alternately arranged along the length direction of the first reinforcing bars, and connecting holes are provided on multiple sets of connecting cylinders.

[0010] According to a preferred embodiment, multiple sets of bidirectional support columns are sleeved on the bearing connecting shaft, and multiple sets of bidirectional support columns and multiple sets of extended support arms are connected by threads. Multiple sets of fixed connection holes are opened on multiple sets of bidirectional support columns and multiple sets of extended support arms, and fixed bolts are passed through multiple sets of fixed connection holes to connect multiple sets of bidirectional support columns and multiple sets of extended support arms.

[0011] According to a preferred embodiment, the multiple sets of extended support arms are respectively connected to the two sets of connecting cylinders. When the multiple sets of extended support arms and the multiple sets of connecting cylinders are all connected by the multiple sets of fixing bolts, the multiple sets of extended support arms and the multiple sets of bidirectional support columns are spirally distributed between the two sets of connecting discs.

[0012] According to a preferred embodiment, both sides of the two sets of connecting discs are provided with multiple sets of connectors, and both ends of the multiple sets of second reinforcing bars are connected to the multiple sets of connectors by welding. The multiple sets of fixing rings are welded to the multiple sets of first reinforcing bars and the multiple sets of second reinforcing bars. The two sets of fixing connecting blocks are connected by multiple sets of bidirectional threaded shafts. The inner walls of the multiple sets of fixing connecting blocks are provided with washers. Limiting holes are opened on both sides of the bearing connecting shaft, the multiple sets of fixing connecting blocks, and the washers.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The device features a design where a bidirectional support column is threadedly connected to an extended support arm, and the extended support arm is helically connected to a connecting cylinder. This design allows for more even distribution of force, improving the device's stability. The device can be easily disassembled and assembled by connecting the extended support arm and the connecting cylinder with fixing bolts, enabling rapid replacement of damaged components and enhancing its maintainability.

[0014] 2. When using this device, multiple sets of first perforations are arranged equidistantly along the diameter of the connecting disc, with the hole positions decreasing in radius from the outside in. This allows the first reinforcing bar to be inserted into the corresponding perforation according to the reduction in the diameter of the tied reinforcing bar, enabling the device to adjust the diameter of the inner support structure and improving its adaptability. Furthermore, the distance between the first reinforcing bars is adjusted by connecting the fixed connecting blocks with bidirectional threaded shafts, further adapting the device to different specifications and optimizing its applicability to various types of reinforcing cage fabrication, thus improving its versatility in application.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0018] Example: like Figures 1 to 3As shown, an adjustable steel cage internal support structure includes multiple sets of first steel bars 11 and two sets of connecting discs 12. Multiple sets of first through holes 13 are opened on both sets of connecting discs 12, and the multiple sets of first steel bars 11 are inserted through the multiple sets of first through holes 13. A second through hole 14 is opened in the middle of both sets of connecting discs 12. The two sets of connecting discs 12 are connected by a bearing connecting shaft 15 passing through the second through hole 14. Fixed connecting blocks 16 for adjusting the distance between the multiple sets of first steel bars 11 are provided on both sides of the two sets of connecting discs 12. Multiple sets of bidirectional support columns 17 are provided between the two sets of connecting discs 12, and each end of the multiple sets of bidirectional support columns 17 is provided with an extended support arm 18. Multiple sets of second steel bars 19 and multiple sets of fixing rings 21 for auxiliary fixing are provided between the two sets of connecting discs 12, and the multiple sets of fixing rings 21 are all located between the two sets of bidirectional support columns 17.

[0019] Specifically, multiple sets of first reinforcing bars 11 serve as the radial support portion of the internal bracing structure, penetrating multiple sets of first perforations 13 on the two sets of connecting discs 12 to provide necessary radial support force for the reinforcing cage and maintain the stability of its circumferential shape. The two sets of connecting discs 12 are connected by a bearing connecting shaft 15 passing through a second perforation 14, forming the basic framework of the internal bracing structure. The bearing connecting shaft 15 plays a crucial role in connection and positioning, ensuring the relative positions of the two sets of connecting discs 12 are fixed, making the entire internal bracing structure a unified whole. Fixed connecting blocks 16 are located on both sides of the connecting discs 12. Their main function is to adjust their own position to change the distance between the multiple sets of first reinforcing bars 11, thereby adapting to the manufacturing requirements of reinforcing cages with different diameters and enhancing the stability and versatility of the internal bracing structure.

[0020] Multiple sets of first through holes 13 are arranged at equal intervals along the diameter of the connecting disc 12, and the hole positions of multiple sets of first through holes 13 decrease sequentially from the outside to the inside along the radius of the connecting disc 12. When the diameter of the tied reinforcing bar is reduced, multiple sets of first reinforcing bar strips 11 are inserted into the corresponding first through holes 13.

[0021] Specifically, the arrangement of multiple sets of first perforations 13 at equal intervals along the diameter of the connecting disc 12 ensures that the first reinforcing bars 11 are evenly distributed in the circumferential direction, thereby ensuring uniform support force on the reinforcing cage and preventing deformation caused by uneven local stress. The arrangement of the holes decreasing in size from the outside to the inside along the radius provides convenience for adapting to reinforcing cages of different diameters. When the diameter of the tied reinforcing bars becomes smaller, the first reinforcing bars 11 can be inserted into the perforations with smaller radii, realizing the adjustment of the diameter of the internal support structure. This allows the internal support structure to better adapt to various reinforcing cages, improving the practicality of the device.

[0022] Each of the multiple sets of first reinforcing bars 11 has two sets of threaded wires at both ends, and the two sets of connecting discs 12 are located between the two sets of threaded wires. The two sets of connecting discs 12 are connected to the multiple sets of first reinforcing bars 11 by multiple sets of bolts.

[0023] Specifically, the two sets of threaded lines at both ends of the first reinforcing bar 11 provide a foundation for the installation of the connecting discs 12. The two sets of connecting discs 12 are located between the threaded lines and are connected to the first reinforcing bar 11 by multiple sets of bolts. This allows for force transmission, ensuring the stability of the internal support structure. Furthermore, it facilitates fine-tuning of the relative positions of the connecting discs 12 and the first reinforcing bar 11 during installation, simplifying construction and improving the assembly efficiency of the internal support structure. Multiple sets of connecting cylinders 22 are provided on the multiple sets of first reinforcing bars 11, and the two sets of connecting cylinders 22 are alternately arranged along the length of the first reinforcing bar 11. Each set of connecting cylinders 22 has connecting holes.

[0024] Specifically, multiple sets of connecting cylinders 22 are arranged alternately along the length of the first reinforcing bar 11, increasing the number of nodes that can be connected on the first reinforcing bar 11. The connecting holes opened on the connecting cylinders 22 provide connection positions for other components such as the extended support arm 18, allowing the various components of the internal support structure to be connected through these connecting holes, thereby constructing a more complex and stable spatial structure and enhancing the support capacity and overall stability of the internal support structure in different directions.

[0025] Multiple sets of bidirectional support columns 17 are all sleeved on the bearing connecting shaft 15, and multiple sets of bidirectional support columns 17 and multiple sets of extended support arms 18 are all connected by threads. Multiple sets of fixed connection holes are opened on multiple sets of bidirectional support columns 17 and multiple sets of extended support arms 18, and fixed bolts are passed through multiple sets of fixed connection holes on multiple sets of bidirectional support columns 17 and multiple sets of extended support arms 18.

[0026] Specifically, multiple sets of bidirectional support columns 17 are fitted onto the load-bearing connecting shaft 15, becoming an important component of the axial support of the internal bracing structure. The bidirectional support columns 17 are connected to the extended support arms 18 by threads. This connection method facilitates the adjustment of the angle and position of the extended support arms 18 to accommodate steel cages of different shapes and sizes. Multiple sets of fixing connection holes on the bidirectional support columns 17 and the extended support arms 18 are used to connect them with fixing bolts, further ensuring the stability of the connection. This allows the bidirectional support columns 17 and the extended support arms 18 to work together, enhancing the axial and radial load-bearing capacity of the internal bracing structure.

[0027] like Figures 2 to 5 As shown, multiple sets of extended support arms 18 are connected to two sets of connecting cylinders 22 respectively. When multiple sets of extended support arms 18 and multiple sets of connecting cylinders 22 are connected by multiple sets of fixing bolts, multiple sets of extended support arms 18 and multiple sets of bidirectional support columns 17 are spirally distributed between the two sets of connecting discs 12.

[0028] Specifically, multiple sets of extended support arms 18 are connected to the connecting cylinders 22 via fixing bolts, and are spirally distributed between the two sets of connecting discs 12, along with the bidirectional support columns 17. This spiral distribution structure allows the force to be evenly distributed throughout the entire structure along the spiral path when the internal support structure is subjected to external forces, improving the stability and load-bearing capacity of the internal support structure compared to the traditional simple support layout. At the same time, the spiral distribution also increases the space utilization rate of the structure, enabling the internal support structure to provide stronger support within a limited space and better ensuring the stability of the steel cage during construction.

[0029] Both sides of the two sets of connecting discs 12 are provided with multiple sets of connectors 23, and both ends of the multiple sets of second steel bars 19 are connected to the multiple sets of connectors 23 by welding. Multiple sets of fixing rings 21 are welded to the multiple sets of first steel bars 11 and the multiple sets of second steel bars 19. The two sets of fixing connecting blocks 16 are connected by multiple sets of bidirectional threaded shafts 24. The inner walls of the multiple sets of fixing connecting blocks 16 are provided with washers 25. Limiting holes are opened on both sides of the bearing connecting shaft 15, the multiple sets of fixing connecting blocks 16, and the washers 25.

[0030] Specifically, multiple sets of connectors 23 on both sides of the two sets of connecting discs 12 provide connection points for multiple sets of second reinforcing bars 19. The two ends of the second reinforcing bars 19 are connected to the connectors 23 by welding, enhancing the integrity and stability of the internal support structure in the circumferential direction and further reinforcing the structure of the reinforcing cage. Multiple sets of fixing rings 21 are welded to the first reinforcing bars 11 and the second reinforcing bars 19, serving as auxiliary fixation, limiting the relative displacement between the reinforcing bars, and making the internal support structure more robust. The two sets of fixing connecting blocks 16 are connected by multiple sets of bidirectional threaded shafts 24. Operators can adjust the distance between the fixing connecting blocks 16 by rotating the bidirectional threaded shafts 24, thereby adjusting the distance between the multiple sets of first reinforcing bars 11 to meet the size requirements of different reinforcing cages. Washers 25 installed on the inner wall of the fixing connecting blocks 16 reduce friction and wear between connecting parts, extending the service life of the internal support structure. The limiting holes on both sides of the bearing connecting shaft 15 and the multiple sets of fixed connecting blocks 16 and washers 25 can be used to insert limiting pins and other components to further fix the position of the connecting components, prevent the components from loosening due to vibration or external force during use, and ensure that the internal support structure always remains stable and reliable.

[0031] The specific usage and function of this embodiment are as follows: First, multiple sets of first reinforcing bars 11 are passed through multiple sets of first perforations 13 on two sets of connecting discs 12. The first reinforcing bars 11 serve as radial supports, maintaining the stability of the circumferential shape of the reinforcing cage. The two sets of connecting discs 12 are connected by a bearing connecting shaft 15 passing through a second perforation 14, forming a basic frame. The bearing connecting shaft 15 ensures that the relative positions of the connecting discs 12 are fixed. When encountering the need to manufacture reinforcing cages of different diameters, the distance between the first reinforcing bars 11 can be changed by adjusting the fixing connecting blocks 16 on both sides of the connecting discs 12. At the same time, taking advantage of the characteristic that the first perforations 13 decrease in size from the outside to the inside along the radius of the connecting discs 12, when the diameter of the tied reinforcing bars is reduced, the first reinforcing bars 11 are passed through the corresponding perforations to adjust the diameter of the internal support structure. The two ends of the first reinforcing bars 11 are connected to the connecting discs 12 by bolts through threaded lines, which facilitates fine-tuning of the position and improves assembly efficiency. Multiple sets of connecting cylinders 22 are arranged alternately along the length of the first reinforcing bars 11, and their connecting holes provide connection points for components such as the extended support arms 18, constructing a complex and stable spatial structure. The bidirectional support column 17 is fitted onto the load-bearing connecting shaft 15 as axial support. It is threadedly connected to the extended support arm 18 and reinforced with fixing bolts passing through the fixing connection hole, allowing for angle and position adjustment. After multiple sets of extended support arms 18 are connected to the connecting cylinder 22 with fixing bolts, they are spirally distributed between the connecting discs 12 along with the bidirectional support column 17, evenly distributing external forces, enhancing stability and load-bearing capacity, and improving space utilization. The connecting heads 23 on both sides of the two sets of connecting discs 12 are welded with second reinforcing bars 19, and fixing rings 21 are welded to the first reinforcing bar 11 and the second reinforcing bar 18 for auxiliary fixation, preventing the reinforcing bars from shifting. The operator adjusts the distance of the fixing connection block 16 by rotating the bidirectional threaded shaft 24, thereby adjusting the spacing of the first reinforcing bar 11 to meet the requirements of different reinforcing cage sizes. The inner wall washer 25 of the fixing connection block 16 reduces friction and wear. Limiting pins can be inserted into the limiting holes on both sides of the load-bearing connecting shaft 15, the fixing connection block 16, and the washer 25 to prevent components from loosening, ensuring that the internal support structure always plays a stable and reliable supporting role during the construction of the reinforcing cage.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
