Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a stable bridge protection guardrail. Background Art

[0002] Bridge construction involves reserved openings and edge protection for high-altitude operations. Specifically, a protective guardrail is set up on the edge. When the protective guardrail is installed, its columns are fixed by expansion bolts or welding with embedded steel bars, and a steel pipe oblique support is set on the back side of the guardrail. This structure is troublesome to install and disassemble, and has a low turnover rate.

[0003] The application with publication number CN116856317A discloses a traffic maintenance robot based on road maintenance, including a telescopic guardrail, a work box installed on the telescopic guardrail, and an adjustment component and a traffic maintenance component arranged on the work box. The guardrail saves space and has a good construction warning effect, but its stability is poor and it is only suitable for road maintenance. The application with publication number CN116856317A discloses a guardrail device for construction projects, which drives the moving plate to move to the right by pulling the operating lever upward, and drives the universal wheel to rotate downward and unfold through the spur rack and spur gear, so that the universal wheel forms a support with the ground, thereby facilitating the movement of the device and improving the on-site construction efficiency. However, in the event of severe weather such as strong winds, the guardrail is easy to fall under the bridge, and the safety and stability are poor.

[0004] During the construction of bridge projects, due to the complicated construction procedures, the edge protection requirements for high-altitude operations must be firm and reliable. While considering construction efficiency, safety and turnover costs, the quality of finished product protection must also be taken into account. The existing protective guardrails all have certain drawbacks. Utility Model Content

[0006] The technical solution of the utility model is:

[0007] A stable bridge protection guardrail comprises two columns, a scissor-type telescopic rod, two connecting sleeves, two groups of diagonal brace assemblies and two U-shaped embedded bolts. The scissor-type telescopic rod is connected between the two columns. The top ends of the two connecting sleeves are rotatably connected to the bottom ends of the two columns through bearings respectively. The inner wall of each connecting sleeve is provided with an internal thread. The two U-shaped embedded bolts are respectively embedded and fixed at the positions where the two columns are installed on the bridge. Both ends of each U-shaped embedded bolt extend to the outside of the bridge. The two connecting sleeves are respectively threadedly connected to one end of the two U-shaped embedded bolts. The top ends of the two groups of diagonal brace assemblies are respectively connected to the two columns, and the bottom ends of the two groups of diagonal brace assemblies are respectively connected to the other ends of the two U-shaped embedded bolts.

[0008] After the two columns are connected to the bridge, a protective mesh is connected between the two columns.

[0009] The two groups of diagonal brace assemblies both include a basket bolt, the bottom end of the basket bolt is connected to the other end of the U-shaped embedded bolt or is connected to the other end of the U-shaped embedded bolt through a wire rope, and the top end of the basket bolt is connected to the corresponding column or is connected to the corresponding column through a wire rope.

[0010] When the two columns are installed on the bridge deck on the inner side of the bridge crash barrier, the two U-shaped embedded bolts are respectively embedded and fixed on the bridge deck on the inner side of the crash barrier, the connecting sleeves at the bottom ends of the two columns are respectively threadedly connected to one of the end heads of the two U-shaped embedded bolts, the top of the crash barrier is embedded with embedded steel bars, and the two groups of diagonal bracing assemblies include an inner diagonal bracing assembly and an outer diagonal bracing assembly, the two ends of the inner diagonal bracing assembly are respectively connected to the other end heads of the U-shaped embedded bolts and the corresponding columns, and the two ends of the outer diagonal bracing assembly are respectively connected to the embedded steel bars and the corresponding columns.

[0011] When the two columns are installed on the top of the bridge crash barrier, the two U-shaped embedded bolts are respectively embedded and fixed on the top of the crash barrier, and one end of each U-shaped embedded bolt is located on the inner side of the other end, the connecting sleeves at the bottom ends of the two columns are respectively threadedly connected to one end of the two U-shaped embedded bolts, the top ends of the two groups of diagonal brace assemblies are respectively connected to the two columns, and the bottom ends of the two groups of diagonal brace assemblies are respectively connected to the other ends of the two U-shaped embedded bolts.

[0012] The bottom ends of the two groups of diagonal brace assemblies are both connected with the connecting sleeves, and the bottom ends of the diagonal brace assemblies are threadedly connected with the other ends of the U-shaped embedded bolts through the connecting sleeves.

[0013] A row of vertically arranged ear plates is arranged on each of the two upright posts.

[0014] Advantages of the utility model:

[0015] The utility model provides a connecting sleeve at the bottom end of each column, which is threadedly connected to the embedded bolts through the connecting sleeve, which greatly improves the stability of the guardrail column support. The connecting sleeve and the column are in a rotational connection relationship, which facilitates the connection sleeve to rotate relative to the column to achieve a stable connection with the embedded bolts.

[0016] The diagonal brace assembly of the utility model adopts a turnbuckle bolt, which is convenient for adjusting the length of the diagonal brace assembly and is convenient for disassembly and reuse.

[0017] The bottom ends of the two groups of diagonal brace assemblies of the utility model are both connected with connecting sleeves, so that the bottom ends of the diagonal brace assemblies can be quickly threadedly connected with U-shaped embedded bolts or embedded steel bars.
