[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0023] Reference Figure 1-5A green construction site enclosure includes two side posts 1. When construction is required, the side posts 1 can be used to block the construction site, facilitating the assembly and use of the enclosure. Two U-shaped fixing rods 3 are connected between the two side posts 1 via an installation mechanism 2. When assembling the enclosure, the side posts 1 and fixing rods 3 are assembled last to prevent assembly inefficiencies caused by incorrect assembly sequence. After all the structures between the two fixing rods 3 are assembled, the fixing rods 3 are then fixedly connected to the side posts 1 via the installation mechanism 2, facilitating the formation of the enclosure by the fixing rods 3 and the structures on them. Several guardrail bars 5 are threadedly connected by screws 4. During assembly, the guardrail bars 5 are first fixed to the lower fixing rods 3 using screws 4. Then, the upper fixing rods 3 are placed onto the guardrail bars 5, and the guardrail bars 5 are fixed to the two fixing rods 3 using screws 4. The guardrail bars 5 can be easily fixed by rotating them. Several side guardrail bars 6 are fixedly connected to the surface of the guardrail bars 5. The side guardrail bars 6 enhance the protective performance of the guardrail bars 5. The side guardrail bars 6 fit together to improve protection and safety. The inner surface of the fixing rods 3... Two locking blocks 7 are fixedly connected to the fixed rod 4. The locking blocks 7 can restrict the limiting block 11 at one end of the screw 4 to prevent the screw 4 from completely entering the interior of the barrier rod 5. A U-shaped anti-moving sleeve 8 is sleeved on the surface of the fixed rod 3. Anti-detachment blocks 9 are fixedly connected to both ends of the anti-moving sleeve 8. After the barrier rod 5 is fixed to the fixed rod 3, the anti-moving sleeve 8 is put on the fixed rod 3. The anti-moving sleeve 8 can be locked on the fixed rod 3 by the anti-detachment blocks 9. It can only be pulled from the side to make the anti-moving sleeve 8 leave the fixed rod 3. After the side stop 1 is fixedly connected to the fixed rod 3, the anti-moving sleeve 8 cannot be detached from the fixed rod 3, thus preventing the fixed rod 3 from being completely locked. The internal bolts 202 are protected to prevent them from coming loose and to prevent them from being corroded and rusted by rainwater, thus protecting their normal use. The anti-loosening block 9 is attached to the surface of the adjacent fixing rod 3. The attachment of the anti-loosening block 9 to the fixing rod 3 prevents the fixing rod 3 from sliding with the anti-moving sleeve 8, ensuring that the anti-moving sleeve 8 stably protects the fixing rod 3. Furthermore, the side stop 1 prevents the anti-moving sleeve 8 from coming loose from the fixing rod 3. When disassembly is required, it can be easily disassembled by rotating the screw 4, without any inconvenience in disassembly affecting its use.
[0024] Furthermore, the installation mechanism 2 includes two U-shaped mounting blocks 201 fixedly connected to the side of the side support column 1. The surface of the mounting block 201 is threaded with bolts 202, which pass through the surface of the adjacent fixed rod 3. After the structure between the two fixed rods 3 is installed, the side support column 1 is moved to the fixed rod 3 so that the two mounting blocks 201 are aligned with the two fixed rods 3 respectively. Then, the fixed rods 3 are fixedly connected to the mounting blocks 201 by the bolts 202. The two side support columns 1 can fix the two fixed rods 3, ensuring stability during use. The two side support columns 1 support the fixed rods 3 to protect the construction site.
[0025] Furthermore, a U-shaped compression rod 10 is fixedly connected inside the anti-movement sleeve 8, and a limit block 11 is fixedly connected to one end of several screws 4. When the anti-movement sleeve 8 is fitted onto the surface of the fixed rod 3, the compression rod 10 can enter the interior of the fixed rod 3. The limit block 11 is located on the outer surface of the locking block 7. The compression rod 10 can compress the limit block 11, so that the limit block 11 is restricted by the locking block 7 and the compression rod 10, and cannot rotate, thus preventing it from moving up and down. This restricts the screws 4 on the limit block 11, so that there will be no slippage between the fixed rod 3 and the enclosure rod 5, and it can be used stably, ensuring the stability of the enclosure rod 5 and the fixed rod 3.
[0026] Furthermore, a base 12 is fixedly connected to the bottom of the side guard post 1, and a protective cover 13 is slidably connected to the top of the side guard post 1. The base 12 can increase the stability of the side guard post 1. With the base 12, which has a large weight and area, the center of gravity of the side guard post 1 is lowered to close to the ground, so that the side guard post 1 can be easily stabilized. The side guard post 1 is hollow inside, which reduces the weight of the side guard post 1 itself, thereby reducing costs and transportation difficulties. When the side guard post 1 is about to be used, the top of the side guard post 1 can be covered by the protective cover 13, so that the internal space of the side guard post 1 will not enter the debris and rainwater, making it convenient for the side guard post 1 to be used.
[0027] Furthermore, a receiving groove 14 is provided on the side of the two side guard posts 1 that are close to each other. A light strip 15 is fixedly connected inside the receiving groove 14. Both sides of the side guard post 6 are arc-shaped. At night, the light strip 15 inside the receiving groove 14 is activated and can emit light. The light from the light strip 15 can illuminate both sides of the side guard post 6 from the side, and then the light is refracted and reflected by the arc-shaped sides, thereby illuminating the side guard post 6. While not dazzling, it can play the role of illumination, reminding pedestrians and vehicles that the construction site is blocked and cannot be passed.
[0028] Furthermore, the top and bottom of the enclosure rod 5 are provided with mounting grooves 16, and the surface of the enclosure rod 5 is provided with two observation grooves 17. When it is necessary to fix the enclosure rod 5 to the fixing rod 3 by means of screws 4, the screws 4 can be inserted into the inside of the mounting groove 16 first, and then the position of the screws 4 can be observed through the observation grooves 17. The position of the screws 4 can be adjusted so that the screws 4 contact the threaded groove at the bottom of the mounting groove 16, and then the screws 4 can be rotated. This makes it easy for the screws 4 to fix the fixing rod 3 to the enclosure rod 5.
[0029] In summary:
[0030] During construction, fencing is required to enclose the construction site and prevent vehicles and pedestrians from entering. When using the fencing, it needs to be assembled. First, several fencing rods 5 are fixed to the fixing rod 3 using screws 4. To fix the fencing rods 5, the screws 4 are inserted into the mounting groove 16. The position of the screws 4 is observed through the observation groove 17, allowing for easy threading of the screws 4 into the deep threaded groove of the mounting groove 16. During this process, the limiting block 11 on the screws 4 contacts the locking block 7 and cannot continue to rotate. Then, the anti-moving sleeve 8 is placed on the fixing rod 3. The anti-detachment block 9 ensures that the anti-moving sleeve 8 can only slide out of the fixing rod 3 from the side. The pressing rod 10 on the anti-moving sleeve 8 can press against the limiting block 11, working with the locking block 7 to ensure the stability of the screws 4, preventing the fencing rods 5 from shaking. Finally, the two side posts 1 are moved to both ends of the fixing rod 3 and fixed using the mounting block 201 and bolts 202. The pole 3 is fixed to the side barrier post 1, so that the side barrier post 1 supports the fixed pole 3. The bottom of the side barrier post 1 is stabilized by the base 12. The internal space of the side barrier post 1 is covered by the protective cover 13. When used at night, the LED lights on the light strip 15 inside the receiving slot 14 can be activated to illuminate the side barrier post 6. The light is then reflected by the two sides of the arc-shaped side barrier post 6, so that the side barrier post 6 can be illuminated, indicating the location of the fence to passers-by. With the above structure, the fence can be easily assembled and disassembled when construction is required, thereby improving the efficiency of assembly and disassembly during the use of the fence. It can also improve the stability between the fence pole 5 and the fixed pole 3, ensuring safety during use. At night, the LED lights on the light strip 15 can illuminate the side barrier post 6, enhancing visual appeal without causing light pollution and glare due to direct lighting, so that passers-by can clearly see the location of the fence at night.
