Description

Technical Field

[0001] The utility model relates to the technical field of construction fences, and specifically provides a fence. Background Art

[0002] In various engineering operations such as construction and road maintenance, construction fencing is an important facility to ensure the safety of the construction site and isolate the work area from the external environment. Its main function is to prevent unrelated personnel and vehicles from mistakenly entering the construction area and reduce the occurrence of safety accidents. At the same time, it can also play a certain dust-proof and sound-insulating effect.

[0003] However, existing construction fences have many problems in actual use, among which the limited warning effect is a more prominent point. At present, the warning signs of most construction fences are simple patterns and texts, which can play a certain warning role in the daytime when there is sufficient light. However, at night or in bad weather conditions, such as heavy rain and heavy fog, the visibility of these signs is greatly reduced, making it difficult to attract the attention of passers-by and vehicles, and unable to convey danger information in a timely and effective manner, thereby increasing safety hazards.

[0004] In addition, the installation process of existing construction fences is also extremely inconvenient. Their structural design is often complex and has many components. The installation requires the collaboration of multiple people, which consumes a lot of manpower and time. Moreover, some fences also require the use of professional tools and equipment during the installation process, which places high technical requirements on the installers. In some emergency construction or limited site conditions, this inconvenient installation method will seriously affect the construction progress and increase construction costs.

[0005] In summary, the existing construction fences have obvious deficiencies in warning effect and installation convenience, and there is an urgent need to develop a new type of construction fence to solve the above problems. Utility Model Content

[0051] The following combination Figures 1 to 9 , describe the technical solution of the utility model:

[0052] An embodiment of the present invention provides a fence, which includes: a frame 100 and a support leg 300 mounted on the bottom end of the frame 100; wherein the frame 100 is divided from top to bottom into a hollow area and a first installation area and a second installation area; a mesh panel unit 200 is arranged in the first installation area and the second installation area; an LED board 400 is installed on one side of the mesh panel unit 200 in the first installation area; a voice warning board 500 is installed on one side of the mesh panel unit 200 in the second installation area; a connecting component 600 is provided between two adjacent frames 100, with its two ends respectively connected to the two adjacent frames 100; an auxiliary fixing component 700, one end of which is connected to the upper part of the frame 100, and the other end is connected to the ground behind the frame 100.

[0053] In the above embodiment, when installing the enclosure, the ground gravel at the edge of the isolation area is cleaned, and then a plurality of support legs 300 are placed at intervals along the edge of the isolation area to form a linearly distributed support leg 300 line, and the support legs 300 are grouped in pairs, and each group of support legs 300 is used to connect a frame 100. After the support legs 300 are arranged, the plurality of frames 100 are moved to the side of the support leg 300 line and placed, and then the frame 100 is erected and placed on the group of support legs 300 from top to bottom, so that the support legs 300 are stuck at the bottom end of the frame 100, and the support legs 300 are placed horizontally and perpendicular to the plane where the frame 100 is located, so that the installed frame 100 and the support legs 300 are L-shaped, and the frame 100 is preliminarily fixed by the support legs 300, and then sandbags are placed on the support legs 300 to fix the support legs 300.

[0054] Furthermore, after each frame 100 is installed on each set of legs 300 , two adjacent frames 100 are fixed together by the connecting assembly 600 .

[0055] Furthermore, after connecting adjacent frames 100 , one end of the auxiliary fixing assembly 700 is fixed to the side of the frame 100 close to the isolation area, and then the other end of the auxiliary fixing assembly 700 is connected to the ground in the isolation area to further fix the frame 100 .

[0056] Furthermore, after all the above steps are completed, check the flow of people outside the isolation area, install the LED board 400 and the voice warning board 500 on the frame 100 where there is a lot of traffic, and after the installation is completed, perform wiring and power the LED board 400 and the voice warning board 500 through the wires. In the evening when the light is dim, the LED board 400 displays a warning sign to remind passers-by that construction is going on ahead. When pedestrians get too close to the fence, the voice warning board 500 plays a voice reminder to detour.

[0057] Reference Figures 1 to 9 In some embodiments, the frame 100 includes: two vertically spaced columns 110; a first crossbeam 120 and a fourth crossbeam 150, the first crossbeam 120 and the fourth crossbeam 150 are spaced laterally between the two columns 110, and the first crossbeam 120 and the fourth crossbeam 150 are respectively arranged close to the top and bottom ends of the columns 110; a second crossbeam 130 and a third crossbeam 140, the second crossbeam 130 and the third crossbeam 140 are spaced laterally between the two columns 110; the first crossbeam 120 and the second crossbeam 130 are spaced apart to form the hollow area therebetween; the second crossbeam 130 and the third crossbeam 140 are spaced apart to form the first installation area therebetween; the third crossbeam 140 and the fourth crossbeam 150 are spaced apart to form the second installation area therebetween.

[0058] In the above embodiment, the two ends of the first beam 120, the second beam 130, the third beam 140, and the fourth beam 150 are respectively welded to the adjacent surfaces of the two columns 110. These beams are arranged at intervals, which can improve the overall structural strength of the frame 100. The outer edge of the mesh unit 200 is welded and installed on the adjacent surfaces of the second beam 130 and the third beam 140, as well as the adjacent surfaces of the third beam 140 and the fourth beam 150. These beams divide the frame 100 into multiple installation areas for the mesh units 200. The mesh units 200 are independently welded in these installation areas. When one of the mesh units 200 is damaged, only the damaged mesh unit 200 can be replaced. This not only reduces the suspended area of the mesh unit 200 and improves the durability of the mesh unit 200, but also reduces the replacement cost.

[0059] It is worth mentioning that when the hollow area formed between the first crossbeam 120 and the second crossbeam 130 is used to move the frame 100, the hand can hold the first crossbeam 120 to move it, which is convenient and quick.

[0060] Reference Figures 1 to 9 In some embodiments, the mesh panel unit 200 includes: a rectangular frame 210, which is arranged in the first installation area and the second installation area; a reinforcing plate 230, which is laterally arranged in the rectangular frame 210, and the two ends of the reinforcing plate 230 are connected to the inner wall of the rectangular frame 210; a plurality of strip holes 240, and the plurality of strip holes 240 are linearly distributed along the surface of the reinforcing plate 230, and the strip holes 240 are installed on the back of the LED board 400 or the voice warning board 500; a mesh sheet 220, which is filled and arranged between the rectangular frame 210 and the reinforcing plate 230.

[0061] In the above embodiment, the outer wall of the rectangular frame 210 of the mesh unit 200 is welded in the first installation area and the second installation area, and the mesh 220 is filled between the inner wall of the rectangular frame 210 and the reinforcing plate 230. The mesh 220 can not only reduce the weight of the enclosure for convenient transportation, but also reduce wind resistance. The reinforcing plate 230 can improve the structural strength of the mesh 220. The mesh 220 is not easy to bend and collapse during a collision. A plurality of strip holes 240 are also provided on the surface of the reinforcing plate 230. The strip holes 240 are used to install the back of the LED board 400 or the voice warning board 500.

[0062] Reference Figures 1 to 9In some embodiments, the support leg 300 includes: a cross bar 310, one end of which is arranged close to the bottom end of the column 110, and the other end extends toward one side of the frame 100; an insertion rod 320a, which is arranged on the surface of one end of the cross bar 310 close to the column 110, and the insertion rod 320a and the cross bar 310 are L-shaped; a socket 320b, which is arranged on the end surface of the bottom end of the column 110, and the insertion rod 320a is clamped in the socket 320b; wherein the cross-sections of the insertion rod 320a and the socket 320b are both cross-shaped.

[0063] In the above embodiment, when installing the frame 100, the bottom end of the column 110 of the frame 100 is set toward the top of the insertion rod 320a. In the process of pressing down the frame 100, the insertion rod 320a gradually enters the socket 320b, and the insertion rod 320a and the socket 320b are engaged with each other, thereby achieving rapid fixation of the support leg 300 and the frame 100.

[0064] It is worth noting that the cross-sections of the insertion rod 320a and the insertion hole 320b are both cross-shaped, so that after the insertion rod 320a is inserted into the insertion hole 320b, it cannot rotate, thereby avoiding the problem that the cross bar 310 may be twisted after being hit by this quick-clamp connection method, causing the cross bar 310 to be parallel to the plane where the frame 100 is located, resulting in the bracket being unable to support the frame 100. At the same time, when installing the frame 100, if there is a stone at the bottom end of one of the columns 110, the cross bar 310 at that location cannot be installed on the stone. The cross bar 310 is rotated half a circle and then installed at the bottom end of the column 110, so that the cross bar 310 can be installed avoiding the stone. The cross bar 310 at that location can also be directly removed, and the adjacent frame 100 can be fixed through the connecting component 600 to improve the flexibility of use.

[0065] Reference Figures 1 to 9 In some embodiments, the LED board 400 includes: a light-emitting board body 410, the backlight surface of which is arranged close to the screen unit 200; a first screw 420a, which is provided in plurality, and the plurality of first screws 420a are linearly distributed on the backlight surface of the light-emitting board body 410; a first nut 420b, the first screw 420a passes through the strip hole 240 and is threadedly connected to the first nut 420b; and a light-emitting sticker 430, which is pasted on the side of the reinforcing plate 230 close to the LED board 400.

[0066] In the above embodiment, one side of the light-emitting board body 410 is a light-emitting surface, and the other side is a backlight surface. The backlight surface is threadedly connected to the first nut 420b through the first screw 420a through the bar hole 240. The light-emitting surface is set to the side away from the isolation area. The LED board 400 can be quickly loaded and unloaded through the first screw 420a and the first nut 420b, and the installation position of the LED board 400 can be adjusted portably. The light-emitting sticker 430 is affixed to the surface of the reinforcing plate 230. The frame 100 without the LED board 400 or the voice warning board 500 installed can also have a warning effect through the light-emitting sticker 430.

[0067] Reference Figures 1 to 9 In some embodiments, the voice warning board 500 includes: a mounting plate 510, which is provided on the surface of the mesh panel unit 200; a human body sensing switch 520, which is installed on the mounting plate 510; a microcontroller, whose input pin is connected to the signal output end of the human body sensing switch 520; a voice player 530, whose first output pin of the microcontroller is connected to the power enable end of the voice player 530; a screen flashing warning light 540, whose second output pin of the microcontroller is connected to the power enable end of the screen flashing warning light 540; a second screw 550a, one end of which is connected to the side of the mounting plate 510 close to the mesh panel unit 200; a second nut 550b, which is provided on the side of the reinforcing plate 230 away from the mounting plate 510, and the second screw 550a passes through the strip hole 240 and is threadedly connected to the second nut 550b.

[0068] In the above embodiment, when a pedestrian enters the perimeter of the fence at night, the human body sensing switch 520 captures the infrared signal emitted by the human body, and the signal output end outputs a high-level trigger signal to the input pin of the microcontroller. After the microcontroller receives the trigger signal, the first output pin immediately pulls up the level, and the power circuit of the voice player 530 is turned on through the driving circuit. After the power circuit of the voice player 530 is turned on, the warning voice is played, and at the same time, the second output pin drives the switching circuit of the screen flashing warning light 540, causing the screen flashing warning light 540 to flash red and blue.

[0069] Reference Figures 1 to 9In some embodiments, the connecting assembly 600 includes: a first sleeve 610a and a second sleeve 610b, which are respectively installed on adjacent surfaces of adjacent frames 100; a short-distance steel cable 620, which is respectively arranged between the first sleeve 610a and the frame 100 and the second sleeve 610b and the frame 100; a rubber plug 630, which is provided in two groups, and the two groups of rubber plugs 630 are respectively arranged on the end walls of the opposite surfaces of the first sleeve 610a and the second sleeve 610b; a metal ring 640, which is provided in two groups, and the two groups of metal rings 640 are respectively arranged on the opposite surfaces of the two groups of rubber plugs 630; a bolt 650, one end of which is rotatably connected to the inner wall of one of the metal rings 640, and the other end is threadedly connected to the inner wall of the other metal ring 640.

[0070] In the above embodiment, the first sleeve 610a and the second sleeve 610b are respectively installed on the adjacent surfaces of the adjacent frames 100, and the circumferential outer wall of the first sleeve 610a and the second sleeve 610b close to the frame 100 is welded to the surface of the column 110. When fixing the two adjacent frames 100 by the connecting assembly 600, the first sleeve 610a and the second sleeve 610b are brought together so that the axes of the first sleeve 610a and the second sleeve 610b coincide with each other, and the bolts 650 are tightened. Pass through the first sleeve 610a and the second sleeve 610b, and rotate one end of the bolt 650 to connect to one of the metal rings 640, screw the nut end of the bolt 650, so that the two metal rings 640 are close to each other, and then the metal rings 640 push the rubber plugs 630 at both ends to move closer to each other, and the adjacent surfaces of the rubber plugs 630 abut against the facing surfaces of the first sleeve 610a and the second sleeve 610b, thereby achieving the clamping and tightening of the first sleeve 610a and the second sleeve 610b.

[0071] It is worth noting that one end of the short-distance steel cable 620 is welded to the surface of the column 110, and the other end is welded to the first sleeve 610a or the second sleeve 610b, so that when the planes where the two frames 100 are located have an angle, the short-distance steel cable 620 can change the angle between the axis of the first sleeve 610a or the second sleeve 610b and the column 110, so that adjacent frames 100 can also be fixed by the connecting assembly 600 when they are at a certain angle to each other.

[0072] Reference Figures 1 to 9In some embodiments, the auxiliary fixing assembly 700 includes: a mounting block 710, the bottom surface of which is rotatably mounted on the surface of the second beam 130; a first hook 720a, the mounting end of which is rotatably mounted on the side wall of the mounting block 710; a second hook 720b, the mating end of which is hung on the mating end of the first hook 720a; a steel wire rope 730, one end of which is connected to the mounting end of the second hook 720b; a third hook 740a, the mounting end of which is connected to the other end of the steel wire rope 730; a ground anchor 740b, anchored on the ground, and the mating end of the third hook 740a is hung on the ground anchor 740b; a limiting hole 750, which is provided on the side wall of the second beam 130, and the first hook 720a is clamped in the limiting hole 750 after being folded.
