Description

Technical Field

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

[0002] Protective fencing is a type of fencing used to protect a specific area from external interference or damage. During construction, it's often temporarily installed around a building site to ensure construction safety, maintain order, and protect the surrounding environment. It prevents non-staff from entering the construction site and potentially causing injuries. It also protects construction workers from the external environment.

[0003] Chinese utility model patent CN219864460U discloses a construction safety barrier. The barrier is designed by sliding a T-shaped post on a second fixing block into a T-shaped slot on a first fixing block of an adjacent safety barrier. Furthermore, the ends of the door-shaped block are inserted into fixing holes on the upper base of the adjacent safety barrier, thereby firmly securing adjacent safety gates together and enhancing the barrier's protective effectiveness. However, in practical application, this system still has some shortcomings. In particular, for construction sites with large construction areas, a large number of safety barriers are often required to ensure the safety of the entire construction area. This process not only involves the assembly of multiple units but also requires stable connections between each unit to form a continuous and effective barrier. However, the size and weight of each unit in this patent are relatively large, which significantly inconveniences the transportation and relocation of the barrier. Each time a project is completed or the construction site needs to be moved, the process of disassembling and transporting the barrier consumes a significant amount of time and labor, thus affecting the overall project schedule. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a foldable and easy-to-assemble and disassemble protective fence for construction projects.

[0005] The technical solution of the utility model is: a protective fence for construction projects, including a column with a slot frame and a folding fence installed between the two columns, the top support rods at the left and right ends of the folding fence are respectively rotatably connected to the two columns, and the bottom support rods at the left and right ends of the folding fence are provided with sliding shafts that are compatible with the slot frame, and the sliding shaft is snapped into the slot frame; it also includes a docking plate for connecting two adjacent columns in series, the docking plate is symmetrically provided with convex shafts, and the column is provided with a shaft sleeve that is compatible with the convex shaft, and the convex shaft is snapped into the shaft sleeve on the column on the same side.

[0006] As a preferred technical solution of the present invention, flip frames are rotatably provided on both the front and rear sides of the column.

[0007] As a preferred technical solution of the present invention, screw holes are provided in the flip frame.

[0008] As a preferred technical solution of the present invention, a luminous plate is provided in the middle of the docking plate.

[0009] As a preferred technical solution of the present invention, a warning sign is provided on the top of the docking plate.

[0010] As a preferred technical solution of the present invention, a winding ring is provided on the upper part of the column.

[0011] Beneficial effects: The utility model adopts the design of a folding fence. The whole device can be folded up when not in use, which is convenient for storage and transportation. At the same time, the convex shaft on the docking plate cooperates with the shaft sleeve on the column, so that adjacent columns can be quickly connected to form a stable protective structure. It is easy to install and disassemble, and the fence can be quickly installed and disassembled, thereby improving work efficiency. The sliding shaft cooperates with the groove frame on the column, and when the folding fence is hit by an external impact, the sliding shaft can slide in the groove frame, providing the folding fence with bending and buffer space, thereby improving the overall protective performance of the device. The luminous plate in the middle of the docking plate can improve the visibility of the fence at night or in low light conditions, and the warning sign on the top helps to remind people to pay attention to potential danger areas. The winding ring provided on the upper part of the column can be used to fix ropes or other tools, which increases the functionality of the entire device and facilitates the management of the construction site. When the device is folded and put away, the rope can be passed through the winding ring to be tied and fixed. BRIEF DESCRIPTION OF THE DRAWINGS

The term "based on" means "based at least in part on." The terms "one example embodiment" and "an embodiment" mean "at least one example embodiment." The term "another embodiment" means "at least one additional embodiment." The terms "first," "second," etc. may refer to different or identical objects.

[0020] like Figure 1-Figure 5 As shown, the embodiment of the present invention provides a protective fence for construction projects. Figure 1 The embodiment of the present invention is composed of two unit fences, each unit fence includes two columns 1 and a folding fence 2 installed between the two columns 1. Figure 2 A slot frame 11 is provided on the side wall of the column 1, and the top support rods at the left and right ends of the folding fence 2 are respectively connected to the two columns 1 for rotation. The bottom support rods at the left and right ends of the folding fence 2 are provided with a sliding shaft 21 that is adapted to the slot frame 11, and the sliding shaft 21 is snapped into the slot frame 11. Figure 2 and Figure 4 When the folding fence 2 changes between the folded state and the unfolded state, the sliding shaft 21 will slide in the groove frame 11, and when the folding fence 2 is in the unfolded state, it will be subjected to external impact. The sliding shaft 21 will slide along the groove frame 11, and the folding fence 2 will also deform adaptively accordingly, which can not only reduce the impact force it bears, but also provide a buffering effect for the impacting object, thereby reducing the damage caused by the impact.

[0021] like Figure 3-Figure 5 As shown, in the embodiment of the present invention, two adjacent unit fences are also connected by a docking plate 3, and two protruding shafts 31 are symmetrically provided at the top and bottom of the docking plate 3, and two shaft sleeves 12 adapted to the protruding shafts 31 are symmetrically provided on the column 1. Figure 3 When the protruding shaft 31 is inserted into the shaft sleeve 12 on the same side column 1, the two adjacent unit fences are connected, and the protruding shaft 31 can rotate in the shaft sleeve 12. After the unit fences are connected, the protruding shaft 31 and the docking plate 3 are rotated to change the angle between the two unit fences, thereby adapting to the construction site and setting up a protective fence around the construction site. Figure 4 and Figure 5The embodiment of the utility model can be folded and stowed, thereby reducing the area it occupies and facilitating its transportation and transfer.

[0022] like Figure 3 and Figure 4 As shown, in the embodiment of the present invention, a flip frame 4 is rotatably provided on both the front and rear sides of the column 1, and two screw holes 41 are provided in the flip frame 4. When the entire protective fence is unfolded, the flip frame 4 is flipped open, which can not only increase the ground contact area of ​​the column 1, but also allow screws to be passed through the screw holes 41 and driven into the ground, or a heavy object can be used to press on the flip frame 4, thereby improving the stability of the entire protective fence. A luminous plate 5 is provided in the middle of the docking plate 3 to improve the visibility of the fence at night or in dim light, and a warning sign 6 is provided on the top of the docking plate 3 to warn people to stay away from the construction area. Figure 3 and Figure 5 A winding ring 7 is provided on the upper part of the column 1. When the protective fence is unfolded, the rope is passed through the winding ring and a warning object can be hung on the rope. When the protective fence is folded and retracted, the rope is passed through the winding ring and the folded protective fence can be bundled to facilitate its subsequent transfer.
