Description

Technical Field

[0001] The utility model relates to the technical field of protective devices, in particular to a guardrail used for safe construction of expressways. Background Art

[0002] During highway construction, safety fences are set up at the edge of the construction area to prevent non-construction workers from accidentally entering and causing injuries.

[0003] At present, the guardrail for highway installation and construction mainly consists of two hollow vertical poles and an integrated guardrail body welded between the two vertical poles. Although the guardrail for highway installation and construction of this structure can prevent non-construction personnel from accidentally entering when in use, since the overall weight of the guardrail for highway installation and construction of this structure is relatively light and it is directly placed at the construction site when in use, the guardrail for highway installation and construction of this structure is less stable when in use and is easily blown down in windy weather, which is not convenient for the stable use of the guardrail for highway installation and construction. At the same time, since the overall structure of the guardrail for highway installation and construction of this structure is fixed, it cannot be flexibly adjusted according to the size of the actual transfer space, which makes the transfer of the guardrail for highway installation and construction of this structure more inconvenient.

The problem of inconvenience in transporting the guardrail is solved. On the one hand, the present invention installs a counterweight assembly on the first and second uprights respectively, so that when the guardrail is in use, water can be injected into the water storage box through the one-way water inlet hopper to increase the overall weight of the guardrail, ensure the stable placement of the guardrail when in use, and avoid the disadvantage of the guardrail being blown down in windy weather. On the other hand, hinges are installed on one side of the first and second guardrails, and locking assemblies are installed on the sides of the first and second guardrails facing away from the hinges. When transporting the guardrail, the butterfly nut on the locking assembly can be removed according to the size of the transport space, and the turning block can be separated from the nut head, so that the first and second guardrails can be conveniently folded, so as to reduce the overall space occupied by the guardrail and facilitate the convenient transport and use of the guardrail.
