Description

Technical Field

[0001] The utility model relates to the technical field of placing and transporting steel reinforcement cages, in particular to an easily detachable and adjustable steel reinforcement cage support device. Background Technique

[0002] With the rapid development of our society, the manufacturing technology in the field of highway bridges has become more and more mature, more and more standardized, and the standards have become higher and higher. As the main component of pile foundations or cylindrical piers, the quality of steel reinforcement cages directly affects the quality of the finished pile foundations or cylindrical piers. However, steel reinforcement cages are prone to plastic deformation during processing, transportation, and hoisting. Therefore, support devices need to be arranged inside the steel reinforcement cages. The existing supports are made by welding two steel bars crosswise inside the steel reinforcement cage, and these steel bars need to be cut off when the steel reinforcement cage is hoisted and lowered. This support method has the following disadvantages: First, the heat generated during welding will conduct to the main bars of the steel reinforcement cage, resulting in poor strength of the main bars of the steel reinforcement cage and plastic deformation when subjected to external forces; second, the process of cutting the steel reinforcement cage will prolong the construction time and increase the construction cost; third, some workers are too lazy to cut directly; fourth, the internal support steel bars of the steel reinforcement cage cannot be recycled after being cut, increasing the construction cost. In addition to the above methods, various supports have emerged in the industry, but there are few supports that can take into account the characteristics of recyclability, applicability to steel reinforcement cages of different diameters, and convenient disassembly and assembly. Content of the Utility Model

[0024] The present invention will be further described in detail below with reference to the drawings.

[0025] An easily detachable and adjustable steel cage support device. Please refer to Figures 2 to 6 , which includes three support rods 1 with freely adjustable lengths. The three support rods 1 are hinged to each other in pairs to form a triangular support structure with the corner ends abutting against the inner side of the main bars 4 of the steel cage. One end of each of the two mutually hinged support rods 1 close to the hinge point is bent outward and away from each other to form an offset notch 6 for clamping the stirrups 5 of the steel cage. In the present invention, the three support rods 1 are hinged to each other in pairs to form a stable triangular support structure, and the lengths of the three support rods 1 can be freely adjusted. Therefore, the lengths of the support rods can be adjusted according to the actual size of the steel cage so that the triangular support structure formed by the hinges can be applicable to different steel cage sizes. In the working state, the triangular support structure abuts against and clamps the main bars 4 of the steel cage at the corresponding positions of the steel cage along the radial direction of the steel cage through its outer corner ends, thereby preventing the steel cage from undergoing plastic deformation during transportation, loading and unloading, or hoisting. In addition, please refer to Figure 2 , Figure 5 and Figure 6 , the triangular support structure formed by the three support rods 1 hinged to each other can be clamped and fixed with the stirrups 5 of the steel cage through the offset notch 6, thereby preventing a certain corner end of the triangular support structure from slipping along the length direction of the steel cage and causing the triangular support structure to tilt and lose its supporting effect.

[0026] To make the present utility model easy to install and disassemble, further, in a preferred embodiment, please refer to Figure 2 , the present utility model further includes three pins 2. Pin holes 3 are provided at both ends of the three support rods 1. The three support rods 1 are detachably hinged to each other in pairs through the cooperation of the pins 2 and the pin holes 3 to form a triangular support structure with the corner ends abutting against the inner side of the main reinforcement bars 4 of the steel reinforcement cage.

[0027] Further, in a preferred embodiment, please refer to Figures 2 to 4 , the support rod 1 includes an adjusting rod 102 and end rods 101 connected to both ends of the adjusting rod 102. Threads with opposite helix directions are respectively provided at both ends of the adjusting rod 102. Screw holes for screwing with the adjusting rod 102 are provided on the end rods 101. The pin holes 3 and the offset notches 6 are provided at one end of the end rod 101 away from the adjusting rod 102. Based on the above structural settings, the depth of insertion of the adjusting rod 102 into the end rod 101 can be changed by rotating the adjusting rod 102, thereby adjusting the overall length of the support rod 1.

[0028] To rotate the adjusting rod 102 more labor - saving and conveniently, further, in a preferred embodiment, please refer to Figures 2 to 4 , a knob 103 is provided in the middle of the adjusting rod 102.

[0029] To facilitate material selection and reduce the manufacturing cost of the present utility model, further, in a preferred embodiment, both the adjusting rod 102 and the end rod 101 are made of steel pipes.

[0030] Based on the above description, the usage method or working principle of the present utility model is as follows: Please refer to Figure 2 and Figure 3 , first, according to the size of the steel reinforcement cage, adjust the lengths of the three support rods 1 by rotating the knob 103 or rotating the end rod 101 so that the lengths of the three support rods 1 are slightly less than the diameter of the steel reinforcement cage. Then, form a triangular support structure by hinging the three support rods 1 to each other in pairs through the cooperation of the pins 2 and the pin holes 3. Then, place the triangular support structure inside the steel reinforcement cage, and first roughly adjust the lengths of the support rods by rotating the knob 103, and then finely adjust the lengths of the support rods so that the corner ends of the triangular support structure abut against the inner side of the main reinforcement bars 4 of the steel reinforcement cage, and at the same time, make the stirrups 5 of the steel reinforcement cage snap into the offset notches 6 at the corner ends to form a stable support, that is, the installation of the support device of the present utility model is completed; when it is necessary to disassemble the support device of the present utility model for reuse, the pins 2 can be pulled out from the respective pin holes 3 to separately take out the support rods 1 from the steel reinforcement cage, or rotate the knob 103 to shorten the lengths of the three support rods 1, and then take out the whole support device of the present utility model.

[0031] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and variations.
