Description

Technical Field

[0001] The utility model relates to the field of municipal construction, in particular to a protective fence for municipal construction. Background Art

[0002] Municipal construction mainly refers to municipal infrastructure construction projects. Municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas and towns (villages) to provide paid or free public products and services to residents based on government responsibilities and obligations. Common municipal construction projects include road traffic projects (such as roads, interchanges, squares, transportation facilities, railways, subways and other rail transit facilities and other facilities).

[0003] During municipal construction, especially in road construction, bridge construction, subway construction, etc., guardrails are used for isolation and warning to prevent pedestrians and vehicles from mistakenly entering the construction area and to ensure the safety of construction workers and passers-by.

[0004] With respect to the above-mentioned related technologies, the inventors found that guardrails are generally assembled and placed along the construction route. However, due to the different terrains, corners or obstacles at the construction site, such as 90-degree corners, arc corners or bevel angle designs, the guardrails need to adjust their length and angle in time. However, most traditional guardrails do not have the functions of length adjustment and angle adjustment, and cannot smoothly transition corners or avoid obstacles, resulting in the need to transport a large number of fence accessories for assembly and protection multiple times. The protection terrain cannot be reasonably planned, and even pedestrian traffic is affected, which has certain limitations. Utility Model Content

[0005] The main technical problem solved by the utility model is to provide a guardrail for municipal construction, which can adjust the length and angle of the guardrail according to the terrain of the construction site, so as to reasonably plan the protection terrain and improve the application range of the guardrail.

[0008] By adopting the above technical solution, the telescopic adjustment rod is adjusted to an appropriate length and rotated around the center of the through hole, so as to adjust the protection angle of the guardrail. Then, by rotating the butterfly bolt 1, it is limited to the corresponding limit groove to fix the required protection angle of the guardrail, so as to realize the length and angle adjustment of the guardrail, which is suitable for use in different terrains, improves the application range of the guardrail, and can also reasonably plan the protection terrain.

[0009] In a preferred example, the utility model can be further configured as follows: the telescopic adjustment rod comprises a hollow rod and a rod body slidably connected to the inner side thereof, a movable limit opening is provided on one side of the hollow rod, a limit block is slidably connected in the movable limit opening, one end of the rod body is connected to the limit block, and the other end is rotatably connected to the movable opening, a butterfly bolt 2 is threadedly connected to one side of the hollow rod near the top of the rod body, and one end of the butterfly bolt 2 is in contact with the surface of the rod body.

[0010] By adopting the above technical solution, the rod body telescopes and slides in the hollow rod to adjust the overall length of the telescopic adjustment rod. At the same time, the limit block slides in the movable limit opening to prevent the rod body from separating from the hollow rod. After the rod body is adjusted to a suitable length, the butterfly bolt 2 is rotated to fix the rod body, so that the telescopic adjustment rod is fixed at the required length to improve the applicability of the guardrail.

[0011] In a preferred example, the utility model can be further configured as follows: the support column assembly includes a column and a base connected to the bottom thereof, a warning light is installed on the top of the column, and universal wheels are installed around the bottom of the base.

[0012] By adopting the above technical solution, the column and the base cooperate with the universal wheel, which can better drive the telescopic adjustment rod to rotate around the center of the through hole so as to adjust the protection angle of the protection, and at the same time, the warning light can be used to alert pedestrians to improve the protection effect.

[0013] In a preferred example, the utility model can be further configured as follows: the support rods are respectively connected to the connecting seats, and the remaining support rods are respectively connected to the hollow rods.

[0014] By adopting the above technical solution, the support rod improves the connection stability between the telescopic adjustment rods, strengthens the structural strength of the guardrail, ensures its stable use, and increases its service life.

[0015] In a preferred example, the utility model can be further configured as follows: it also includes a plurality of fluorescent indicator signs, which are respectively connected to the support rods, and are respectively located between two upper and lower adjacent hollow rods, and the fluorescent indicator signs are respectively symmetrically arranged.

[0016] By adopting the above technical solution, the fluorescent signboard is illuminated by the lights of passing vehicles at night, and cooperates with the warning light to remind pedestrians to pay attention to safety, which plays a warning effect and further improves the protective effect of the guardrail.

[0017] In a preferred example, the utility model can be further configured as follows: the opposite sides of the cross bar assembly are symmetrically connected with reinforcing ribs, and the reinforcing ribs are respectively connected to the support column assembly.

[0018] By adopting the above technical solution, the reinforcing ribs improve the connection strength between the support column assembly and the cross bar assembly, making the structure stable during use.

[0019] To sum up, the utility model includes at least one of the following beneficial technical effects of the guardrail for municipal construction: the telescopic adjustment rod adjusts the appropriate length and rotates around the center of the through hole, so as to adjust the protection angle of the guardrail, and then by rotating the butterfly bolt one, it is limited to the corresponding limit groove to fix the required protection angle of the guardrail, so as to realize the length and angle adjustment of the guardrail, which is suitable for use in different terrains, improves the application scope of the guardrail, and can also reasonably plan the protection terrain.
