Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, specifically to a highway construction enclosure device. Background Technology

[0002] Highway construction fencing is a temporary safety protection facility used at highway construction sites to isolate the construction area from the external environment. It plays a vital role in ensuring construction safety, maintaining traffic order, and minimizing the impact of construction on the surrounding environment.

[0003] Currently, most existing highway construction site fencing devices are fixed structures with non-foldable and retractable support frames, resulting in significant space occupation when not in use. Temporary storage at construction sites requires large areas, increasing site management complexity; long-term storage after construction also wastes storage space. Furthermore, during transportation, the large size of the fencing devices limits the capacity of transport vehicles, leading to low efficiency and increased costs. Therefore, we propose a new type of fencing device for highway construction. Utility Model Content

[0004] The main objective of this invention is to provide a construction site enclosure device for highway construction, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a construction site enclosure device for highways, comprising a baffle and a support frame. The support frame consists of a vertical rod and a hinged rod, which are rotatably connected by a hinge shaft. This allows the hinged rod to fold relative to the vertical rod around the hinge shaft, thereby effectively reducing the space occupied by the support frame when not in use and facilitating transportation and storage.

[0006] Preferably, the hinge rod has a fixing hole for fixing to an external connector. A foldable support rod is installed on the inner wall of the hinge rod through a hinge seat. The support rod has a hollow structure, and its inner wall is provided with an internal thread that mates with the thread of the moving rod. The outer surface of the moving rod is machined with a matching external thread, and a threaded groove is provided at the top for connecting an external adjustment tool.

[0007] Preferably, the outer wall of the vertical rod is hinged to a rod body, and the rod body has an external thread that mates with the threaded groove. The external thread of the rod body is in the opposite direction to the external thread of the moving rod.

[0008] Preferably, the outer wall of the vertical rod is fitted with a foldable rod body via a hinge seat, and the rod body is machined with an external thread that matches the threaded groove. This external thread is designed in the opposite direction to the external thread of the moving rod.

[0009] Preferably, the outer wall of the vertical rod is fixedly connected to a stop bar, the stop bar has an installation port, and a pin is provided on the installation port.

[0010] Preferably, a handle is mounted on the outer wall of the baffle via a hinge shaft, and a reinforcing crossbar is provided on the baffle laterally, with insertion holes on the surface of the crossbar.

[0011] Preferably, the enclosure device consists of a set of baffles and two sets of support frames. In the two sets of support frames, the vertical rod sidewall of one set of support frames is fixedly connected to the plug rod, while the vertical rod sidewall of the other set of support frames is provided with plug holes.

[0012] Beneficial effects This utility model provides a fencing device for highway construction. It has the following beneficial effects: (1) The construction site enclosure device for highway construction has a hinged support frame. The hinged rod can be folded relative to the vertical rod around the hinge axis. In the non-use state, it can effectively reduce the space occupied by the support frame. Compared with the traditional fixed structure enclosure, this design greatly reduces the space cost in the transportation and storage process. Whether it is temporary storage at the construction site or long-term storage after the construction is completed, it can reduce the site occupation and improve the space utilization rate. At the same time, it is also convenient for transport vehicles to load more equipment and improve transportation efficiency.

[0013] (2) The highway construction fencing device uses a combination of plug-in connection and threaded locking between its components. Through the cooperation of pins with installation ports and holes, and the quick locking of the reverse threaded pair, construction workers can quickly install and dismantle the fencing without complex tools. During highway construction, the position and quantity of the fencing can be flexibly adjusted according to the construction progress, significantly shortening the time for fencing erection and dismantling, saving a large amount of manpower and time costs, and ensuring the smooth progress of construction.
