Description

Technical Field

[0001] This utility model relates to a linear steel support for a telescopic and adjustable crash barrier template, belonging to the field of highway construction. Background Technology

[0002] The existing crash barrier formwork support system involves installing the inner formwork first, followed by the outer formwork. The outer formwork is fixed to the inner formwork using pre-embedded PVC pipes with tie rods, while the inner formwork is supported by steel pipes and tied with soft steel wire ropes to prevent it from tipping over. This installation method has several drawbacks: 1. Poor overall stability of the crash barrier formwork. The steel pipe supports are prone to loosening during concrete pouring, leading to formwork tipping. 2. Inability to adjust the crash barrier's alignment. After the formwork is fixed with steel pipe supports, if there is a deviation between the inner formwork installation and the already installed and supported formwork, all supporting steel pipes must be removed and readjusted. 3. Inability to precisely control the formwork elevation. When the overall flatness of the beam surface or pavement surface is poor, elevation adjustment cannot be achieved using steel pipes, leading to problems such as formwork bottom detachment or misalignment due to formwork defects. 4. Complex installation and dismantling of the support system. The steel pipe support + soft steel wire rope tie-up method results in a long installation period, requires a large amount of time and labor, and involves a significant workload. Summary of the Invention

[0003] This utility model provides a retractable and adjustable steel support for the linearity of a crash barrier template, which solves the problems of poor overall stability, inability to adjust the linearity of the crash barrier, and poor flexibility of use of traditional crash barrier template steel supports.

[0004] To address the aforementioned issues, a retractable and adjustable anti-collision guardrail template with linear steel support is proposed. This support includes an upper adjusting screw, a lower adjusting screw, a support steel pipe, an upper connecting plate, and a lower connecting plate. The inner walls of both ends of the support steel pipe are threaded with both positive and negative threads, which are then connected to one end of the upper and lower adjusting screws, respectively. The upper connecting plate is a U-shaped plate, and its slotted opening is welded to the other end of the upper adjusting screw to form a single unit. The lower connecting plate is a steel angle plate, with a slotted end that is welded to the other end of the lower adjusting screw to form a single unit. A hole is drilled on the other end of the lower connecting plate, and the plate is fixed to the beam surface by embedding reinforcing bars through the hole. Adjusting nuts of the same diameter are also fitted to both the upper and lower adjusting screws.

[0005] In the aforementioned steel support, the supporting steel pipe is a seamless steel pipe with a diameter of φ48*3.5*900mm;

[0006] In the aforementioned steel support, the upper connecting plate is 2cm thick and is used to connect with the vertical stiffening plate on the inner template of the crash barrier by bolts.

[0007] In the aforementioned steel support, the thickness of the lower connecting plate is 2cm, and the bending angle is 135°;

[0008] In the aforementioned steel support, both the upper and lower adjusting screws are t32*300 screws.

[0009] Compared with existing technologies, this utility model designs the highway crash barrier template support system as a telescopic structure. According to the elevation and linear changes of the top surface of the inner template of the guardrail, the linearity and elevation of the template are adjusted by the upper and lower adjusting screws on the steel support according to the measurement data. After installation, there is no need to reinforce the template. The adjustable steel support will play a role in supporting and pulling, thereby fixing the entire crash barrier template system. This technology has been verified by actual engineering applications and has excellent results. Attached Figure Description

The inner walls of both ends of the support steel pipe 3 are threaded with both positive and negative threads, which are respectively connected to one end of the upper adjusting screw 1 and the lower adjusting screw 2. The upper connecting plate 4 is a U-shaped plate with a thickness of... The upper connecting plate 4 has a groove and is welded to the other end of the upper adjusting screw 1 to form an integral whole. It is used to connect with the vertical stiffening plate on the inner template of the crash barrier by bolts. The lower connecting plate 5 is a steel angle plate with a thickness of 2cm and a bending angle of 135°.
