[0021] Please see Figures 1 to 4 The adjustable assembly type guardrail shown in a preferred embodiment of the application includes a vertical rod 1 and a mesh 2. The vertical rod 1 is provided with a clamping plate 11 at the bottom, the embedded steel bars are fixedly connected with the vertical rod 1 through the clamping plate 11, and a plurality of connecting sliding grooves 12 are arranged on the vertical rod 1. The mesh 2 is arranged on both sides of the vertical rod 1, the side edge of the mesh 2 is provided with a connecting part 21, the connecting part 21 is adjustably and fixedly arranged in the connecting sliding groove 12, and the bottom of the mesh 2 is provided with a skirting board 22.

[0022] Since the existing edge guardrail for bridge deck construction usually adopts the connecting mode of embedded bolts or welding and guardrail embedded steel bars. However, this connecting mode will produce welding slag in three-dimensional expansion construction, especially in the construction environment close to the existing road, thereby producing adverse effects on the original road, and possibly causing damage to the original steel structure. In addition, the traditional guardrail structure generally adopts the form of steel pipe fixed with guardrail mesh 2. This structure not only has low installation efficiency and difficult post-maintenance, but also has poor anti-throwing effect, cannot effectively prevent accidental throwing or falling of objects during construction, and has certain safety hazards.

[0023] Therefore, according to the scheme of the embodiment of the utility model, by adopting the fixed connection mode of the clamping plate 11 and the vertical rod 1, the damage to the original road and the reinforcing steel caused by the traditional welding mode is avoided, and the generation of welding slag is reduced. Meanwhile, the connecting groove 12 on the vertical rod 1 and the connecting part 21 of the mesh 2 can be adjustably connected, the installation position and angle of the mesh 2 can be flexibly adjusted, the installation efficiency is improved, and the post-maintenance is facilitated. In addition, the toe plate 22 arranged at the bottom of the mesh 2 enhances the anti-throwing effect, and can effectively prevent the accidental throwing or falling of objects during construction.

[0024] The following will be described in detail with specific embodiments:

[0025] Please refer to Figure 3 The clamping plate 11 is hinged at the bottom of the vertical rod 1, the bottom of the vertical rod 1 is provided with a plurality of fixed ears 13, and the clamping plate 11 and the fixed ear 13 are connected by a fixed bolt 14 to fix the embedded reinforcing steel between the clamping plate 11 and the vertical rod 1. The structure of the hinged clamping plate 11 and the fixed ear 13 makes the connection of the vertical rod 1 and the embedded reinforcing steel more stable, avoiding the shortcomings of traditional welding (welding slag and damage to the reinforcing steel). The connection mode of the fixed bolt 14 can effectively improve the convenience of assembly and disassembly, and ensure the firmness of the connection.

[0026] Please refer to Figure 1 The connecting part 21 and the connecting groove 12 are fixedly connected by a connecting bolt 211. The connecting bolt 211 realizes the fixation of the connecting part 21 and the connecting groove 12, ensures the fastening relationship between the mesh 2 and the vertical rod 1, improves the installation precision and stability of the guardrail mesh 2, and makes the adjustment during the later maintenance more convenient.

[0027] Please refer to Figure 3 The connecting groove 12 is provided with adjustable bolt holes 121 on both sides, which are used to adjust the fixed position of the connecting bolt 211. The design of the adjustable bolt hole 121 provides flexibility, which can adjust the position and fixation mode of the mesh 2 according to actual needs. This makes the assembly of the guardrail more adaptable, which can meet the needs of different construction environments, further improving the adjustability and multifunctionality of the assembly.

[0028] The upper part of the vertical rod 1 is provided with a signboard, and the lower part of the vertical rod 1 is provided with a toe plate 22. The setting of the signboard improves the identification of the guardrail, especially in the construction site, which can guide the personnel to clearly understand the safety area or the construction area. The design of the toe plate 22 not only increases the structural stability of the guardrail, but also effectively avoids the wear and tear of the object when it contacts the ground during construction, thereby improving the service life and safety of the guardrail.
