Description

Technical Field

[0001] This utility model relates to the field of safety fence technology, specifically a safety fence for construction projects. Background Technology

[0002] Construction safety fences are facilities used on construction sites to delineate safe areas, isolate dangerous areas, and protect personnel safety. They have a certain height and strength, effectively preventing personnel from accidentally entering dangerous construction areas and preventing accidents. At the same time, they can also enclose the construction site, serving as a warning and regulating construction order.

[0003] In environments with uneven terrain, most existing safety fences adopt an integrated straight structure. This structure is prone to tilting during installation due to terrain undulations. When multiple fence units are assembled together, the tilting can lead to inconsistent spacing between fences, or even large gaps. This not only affects the overall aesthetics of the fence, but more importantly, it significantly reduces the fence's barrier performance and weakens its protective effect on personnel and objects, thus failing to effectively ensure the safety of the construction site. Therefore, a safety fence for construction projects is proposed to address the above problems. Utility Model Content

[0029] Please see Figure 1-9 This utility model provides a technical solution:

[0030] A safety fence for construction projects includes a first fence assembly 1, a second fence assembly 2, and a counterweight expansion block 3. The outer side of the first fence assembly 1 is fixed to the inner side of a fixing assembly 4. The first fence assembly 1 includes a fence rod 11, with a base 12 fixedly connected to the bottom end of the fence rod 11. A guide groove 13 and a fixing groove 14 are provided on the inner side of the fence rod 11. A rack 15 is fixedly connected to the inner side of the fixing groove 14. An anti-detachment block 16 is fixedly connected to the top end of the fence rod 11. The fixing assembly 4 includes a frame plate 41, with an adjustment groove 43 and a plate groove 45 provided on the inner side of the frame plate 41. A guide rail 44 is fixedly connected to the inner side of the adjustment groove 43. A guide post 46 is fixedly connected to the inner side of the plate groove 45. A screw 47 is rotatably connected to the inner side of the frame plate 41. A pressure plate 48 is spirally connected to the outer side of the screw 47. A toothed plate 49 is fixedly connected to one side of the pressure plate 48. The guide rail 44 slides on the inner side of the guide groove 13.

[0031] As a further implementation of this solution, the front and rear ends of the frame plate 41 are fixedly connected to the mounting plate 42. The mounting plate 42 has through holes on its inner side. With the above-mentioned setting, it is easy to align and fix multiple fence units with bolts, so as to ensure the integrity and stability of the fence after installation and improve the barrier performance of the fence.

[0032] As a further implementation of this solution, a counterweight expansion block 3 is fixedly connected to the bottom of the second fence component 2. The structure of the second fence component 2 is the same as that of the fence rod 11. The second fence component 2 is slidably connected to the inner side of the adjustment groove 43. Guide grooves 13 are opened at both the front and rear ends of the fence rod 11. The number of guide rails 44 is the same as the number of guide grooves 13. The guide rails 44 are embedded in the inside of the guide grooves 13. The fence rod 11 slides on the inner side of the adjustment groove 43. Through the above settings, the height can be automatically adjusted according to the terrain to ensure that the fence unit adapts to uneven ground and prevents fence tilting and gap problems caused by terrain undulations. With the sliding of the fence rod 11 in the adjustment groove 43, the structural strength and stability of the fence unit are further enhanced, while improving the verticality and aesthetics of the fence.

[0033] As a further implementation of this solution, the adjustment groove 43 extends vertically through the inner side of the frame plate 41, and the adjustment groove 43 is connected to the plate groove 45. The number of adjustment grooves 43 is multiple. Through the above settings, the fence unit is provided with a flexible height adjustment function, ensuring the adaptability and stability of the fence under different terrains, while simplifying the installation process.

[0034] As a further implementation of this solution, the pressure plate 48 is embedded in the inside of the plate groove 45. The front and rear ends of the pressure plate 48 are provided with sliding holes. The pressure plate 48 is slidably connected to the outside of the guide post 46 through the sliding holes. The middle end of the pressure plate 48 is provided with a threaded hole. The toothed plate 49 is located at the right end of the adjusting groove 43. The left end of the toothed plate 49 meshes with the right end of the rack 15. The toothed plate 49 extends into the inside of the fixing groove 14. Through the above settings, the fence units are firmly fixed, preventing the fence from loosening or tilting during use, and ensuring the integrity and safety of the fence.

[0035] Workflow: When installing the safety fence on uneven ground, place the entire device vertically on the ground. Under the weight of the counterweight expansion block 3 and the base 12, the bottom ends of both the counterweight expansion block 3 and the base 12 are in contact with the ground. During this process, the base 12 drives the fence rod 11 to slide inside the adjustment groove 43, and the counterweight expansion block 3 drives the second fence assembly 2 to slide inside another adjustment groove 43. Both the counterweight expansion block 3 and the second fence assembly 2 serve as counterweights. Then, adjust the height of the fixing assembly 4 appropriately. After adjustment, rotate the screw 47. The screw 47 is rotatably connected inside the frame plate 41. The screw 47 drives the outer spirally connected pressure plate 48 to move to the left. The pressure plate 48 slides outside the guide post 46, which limits the leftward movement of the pressure plate 48. The pressure plate 48 drives the toothed plate 49 to move to the left. When the device moves to the left, the toothed plate 49 extends into the adjustment groove 43 and the fixing groove 14, and the toothed plate 49 engages with the rack 15. This fixes the frame plate 41 to the first fence assembly 1 and the second fence assembly 2. After fixing, the height of the multiple second fence assemblies 2 changes according to the terrain, and the frame plate 41 is in a horizontal state. The base 12 is fixed to the ground foundation with bolts. When fixing another frame plate 41, the mounting plate 42 of the other frame plate 41 is aligned with the former and then fixed with bolts. This fixing method can ensure that the fence post 11 or the second fence assembly 2 is in a vertical state, improve the aesthetics after installation, prevent large gaps between them after installation, and thus ensure the barrier performance of the fence, providing a strong guarantee for safe construction.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
