Description

Technical Field

[0001] This utility model relates to the field of steel cage manufacturing technology, and in particular to a jig suitable for installing steel cages for roadside guardrails. Background Technology

[0002] As a crucial safety feature for highways, the manufacturing process of reinforced concrete guardrails directly impacts project quality and protective performance. The fabrication of reinforced concrete guardrails for highway road surveying begins with cutting and bending steel bars to the designed dimensions. These bars are then assembled into guardrail cages through manual binding or welding. Due to the complex cross-sectional shapes and diverse steel bar specifications, construction workers must meticulously check the position, angle, and spacing of each bar and complete high-strength welding or binding operations within confined spaces. This demands exceptional skill and physical strength from the workers, and the welding process is not only difficult to control, but also results in a high rate of rework. Furthermore, the fact that each cage must be handcrafted contributes to low overall production efficiency and a difficult-to-shorten construction period, significantly hindering project progress and cost control.

[0022] Example. A frame suitable for installing roadside guardrail steel cages, structural reference. Figure 1 The system includes a base 1, with several longitudinal steel reinforcement support columns 2 arranged along the length of the base 1 and on its center line. Several longitudinal steel reinforcement support crossbars 3 are arranged from low to high along the height of the longitudinal steel reinforcement support columns 2. Several steel reinforcement grooves 4 are provided on the top surface of the base 1, on the same side as the longitudinal steel reinforcement support crossbars 3, and are arranged along the length of the base 1. The width of the steel reinforcement grooves 4 is greater than the diameter of the steel reinforcement. Three longitudinal steel reinforcement support crossbars 3 are provided, with a one-meter interval between adjacent crossbars. The length of the base 1 is greater than or equal to three meters. The length of the longitudinal steel reinforcement support crossbars 3 and the spacing between the steel reinforcement grooves 4 are determined based on the reinforcement design of the roadside guardrail reinforcement cage. The height of the longitudinal steel reinforcement support columns 2 is greater than that of the roadside guardrail. The steel reinforcement grooves 4 facilitate the installation of the vertical reinforcement and also facilitate the fixing of the vertical reinforcement spacing; the longitudinal steel reinforcement support columns 2 and longitudinal steel reinforcement support crossbars 3 provide temporary support for the longitudinal reinforcement, facilitating the fabrication of the reinforcement cage.

[0023] The base 1 is equipped with support feet 5 on the ground. The support feet 5 facilitate the movement and reuse of this frame.

[0024] A diagonal brace 6 is provided on the side of the longitudinal steel bar support column 2 away from the longitudinal steel bar support crossbar 3. The diagonal brace 6 improves the structural rigidity of the entire frame.

[0025] The method of using this utility model is as follows: Firstly, in the existing technology, the reinforcement design commonly used for roadside guardrail steel cages includes using a single piece of steel. Rebar is bent into vertical bars in one step using a bending machine, such as... Figure 2 As shown, a section of concrete roadside guardrail is set to a length of no more than three meters, and three steel pipe piles are buried at the bottom of the concrete roadside guardrail. The steel pipe piles are spaced one meter apart. Therefore, no steel bar groove 4 or vertical bars are set at the position of the steel pipe piles in the steel cage, so that the steel pipe piles can be inserted into the steel cage. The spacing between the vertical bars is 150 mm, so the center distance between adjacent steel bar grooves 4 is set to 150 mm. The cross section of the concrete roadside guardrail is generally set to gradually decrease in size from low to high. Therefore, the longitudinal steel bar support crossbar 3 is also gradually shortened from low to high. When making the steel cage, several finished vertical bars are placed into the corresponding steel bar grooves 4. Then, the longitudinal steel bars are placed on the longitudinal steel bar support crossbar 3 of the same height and tied or welded to the vertical bars for initial fixation. Then, the longitudinal steel bars are installed on the remaining longitudinal steel bar support crossbar 3 in sequence and welded to the vertical bars to fix them, thus making the steel cage.

[0026] Compared to existing methods of manually fabricating steel cages, this invention reduces construction difficulty and improves construction efficiency. It has already been put into practical use in engineering projects, as shown in the comparison below:

[0027]

[0028] Based on the fact that the total length of the guardrail project on both sides of the roadbed of a certain project is 41,966 meters, the investment cost can be effectively reduced by RMB 1,081,039.83 by adopting this utility model.

[0029] Obviously, the above description is only a part of the embodiments of the present invention, and not all of the embodiments. The above embodiments are not intended to limit the present invention, and various modifications and variations can be made to the present invention by those skilled in the art.
