An assembled fence

Abstract

This utility model relates to a prefabricated fencing in the field of municipal construction. The prefabricated fencing includes a base and two uprights mounted on the base. Each of the two uprights has an installation groove on one side. The fencing is formed by installing the base, two uprights, two crossbars, and multiple ventilation panels with corresponding windbreaks. This facilitates convenient handling and transportation. During installation, only the two uprights, one crossbar, and the base need to be installed first. Then, the U-shaped blocks mounted on both sides of the ventilation panels are placed into the installation grooves, and the other crossbar is installed with the two uprights to form the fencing. The installation process is convenient. Furthermore, if one ventilation panel or its corresponding windbreak is damaged during use, it can be easily replaced by removing the ventilation panel from the U-shaped block and moving it horizontally, eliminating the need to replace multiple windbreaks as a whole, thus reducing costs.

Description

Technical Field

[0001] This utility model relates to the field of municipal construction, and in particular to a prefabricated fence. Background Technology

[0002] Standardized construction site fencing is a crucial aspect of construction and reflects a city's level of civilized construction practices. When using fencing, its installation position needs to be adjusted according to different construction locations to isolate the construction site from the external environment and prevent unauthorized personnel from accidentally entering dangerous areas.

[0003] A search revealed that the Chinese patent for "A Prefabricated Fence" (authorization announcement number CN 213710666 U) describes a prefabricated fence with a windproof baffle comprising a fence base, columns connected to the top of the fence base, and windproof baffles connected between the columns. The windproof baffle includes multiple parallel, spaced-apart inclined baffles and horizontal wind guide plates connected between the ends of adjacent inclined baffles. The horizontal wind guide plates have multiple vertically penetrating air holes, which helps reduce overturning due to wind resistance and effectively ensures the safety of pedestrians and vehicles. Furthermore, the base design improves the impact resistance of the fence's bottom, reduces installation and dismantling time, minimizes traffic pressure on adjacent areas, quickly forms a construction area, accelerates construction progress, and facilitates application to different types of fencing in municipal road reconstruction and expansion projects.

[0004] While the aforementioned application improved the stability of the fencing for protecting the construction area through the air guide holes and base, the windbreak panels and columns in the fencing are integrated, which makes it inconvenient to handle and transport. Furthermore, when the surface of the windbreak panel is damaged, the entire windbreak panel needs to be replaced, increasing costs. Utility Model Content

[0005] Therefore, it is necessary to provide a prefabricated fencing solution to address the problem that the windbreak panels and columns in the above-mentioned scheme are integrated, which leads to inconvenience during handling and transportation, and that the entire windbreak panel needs to be replaced when the surface of the windbreak panel is damaged, increasing costs.

[0006] Includes: a base and two columns mounted on the base, each of the two columns having an installation groove on one side;

[0007] It also includes two crossbars, each with a U-shaped groove at both ends that matches the uprights. The two ends of the crossbars are respectively installed to the two uprights by bolts and nuts.

[0008] It also includes multiple ventilation panels, with a wind baffle fixedly connected to one side of the bottom end of each ventilation panel. The wind baffle is inclined, and U-shaped blocks are installed in the middle of both sides of each ventilation panel. The surface of the U-shaped blocks is slidably connected to the inner wall of the mounting groove, and the surface of the ventilation panel is in contact with the inner wall of the U-shaped blocks. The ventilation panels and U-shaped blocks are installed by bolts and nuts.

[0009] In one embodiment, a movable plate is slidably connected to the inner wall of one of the columns, and a threaded rod is rotatably connected to the lower end of the inner wall of another column. The lower end of the inner wall of the movable plate is threadedly connected to the surface of the threaded rod. Multiple locking blocks are fixedly connected to the side of the movable plate near the mounting groove, and a locking hole is provided on the side of one of the U-shaped blocks away from the ventilation plate. Using multiple locking blocks and multiple locking holes facilitates the reinforcement of the ventilation plate installation via the U-shaped blocks. Furthermore, the locking blocks and locking holes help to fix the installed ventilation plate in a designated position, ensuring that when one ventilation plate and its corresponding windbreak are removed, the other ventilation plates and their corresponding windbreaks remain stable.

[0010] In one embodiment, multiple springs are fixedly connected to both sides of the wind deflector, and a protective plate is fixedly connected to the other end of each spring. By incorporating springs, the protective plate can have a certain amount of expansion and contraction space under the action of wind. The cooperation between the protective plate and the springs helps to disperse wind force, reducing the force exerted by the wind on the wind deflector and thus enhancing its stability during use.

[0011] In one embodiment, a round rod is rotatably connected to both the top and bottom ends of the protective plate, with the surface of the upper round rod contacting the bottom end of the ventilation plate. This helps reduce the friction between the protective plate and the ventilation plate when the protective plate moves.

[0012] In one embodiment, a baffle is fixedly connected to the bottom end of the U-shaped block, and the surface of the baffle is slidably connected to the inner wall of the mounting groove. This facilitates the sealing of the mounting groove by multiple U-shaped blocks and multiple baffles forming a whole after multiple ventilation panels and columns are installed.

[0013] In one embodiment, the end of the card block away from the moving plate is bent into an arc shape, and the shape of the card hole matches the shape of the card block. This facilitates better insertion of the card block into the corresponding card hole.

[0014] In one embodiment, a groove is formed at the lower end of the other side of one of the columns, and the end of the threaded rod away from the mounting groove passes through the groove and is fixedly connected to a knob. This facilitates easier rotation of the threaded rod by the operator, and the knob's placement within the groove helps prevent accidental activation of the knob during use.

[0015] Beneficial effects

[0016] 1. In this solution, the enclosure is formed by installing the base, two columns, two crossbars, and multiple ventilation panels with corresponding wind deflectors. This makes the device easier to handle and transport. When installing the enclosure, it is only necessary to first install the two columns, one crossbar, and the base. Then, the U-shaped blocks installed on both sides of the multiple ventilation panels are placed into the installation slots to form a whole with the corresponding wind deflectors. Finally, the other crossbar is installed with the two columns to form the enclosure. The installation steps are relatively convenient. Furthermore, when one of the ventilation panels and its corresponding wind deflector is damaged during the use of the enclosure, it is only necessary to remove the ventilation panel from the U-shaped block and move it horizontally to remove the ventilation panel for replacement. There is no need to replace multiple wind deflectors as a whole, thus reducing costs.

[0017] 2. After multiple ventilation panels are installed with two columns, multiple clips and multiple clip holes are used to secure them. This helps to reinforce the installation of the ventilation panels with U-shaped blocks. The clips and clip holes also help to fix the installed ventilation panels in the designated position, ensuring that when one ventilation panel and its corresponding wind deflector are removed, the other multiple ventilation panels and their corresponding wind deflectors are in a stable state.

[0018] 3. By incorporating springs, the protective plate can expand and contract under wind force. The cooperation between the protective plate and the springs helps to disperse wind force, reducing the force exerted by the wind on the wind deflector and thus enhancing its stability during use.

[0033] The following is combined with Figures 1-6 This invention describes a prefabricated enclosure.

[0034] In one embodiment, a prefabricated enclosure includes: a base 100 and two columns 200 installed on the base 100, each of the two columns 200 having an installation groove 210 on one side.

[0035] It also includes two crossbars 300, each of which has a U-shaped groove 310 at both ends that matches the column 200. The two ends of the two crossbars 300 are respectively installed to the two columns 200 by bolts and nuts.

[0036] It also includes multiple ventilation panels 400. A wind baffle 500 is fixedly connected to one side of the bottom end of the ventilation panel 400. The wind baffle 500 is set at an angle. U-shaped blocks 410 are installed in the middle of both sides of the ventilation panel 400. The surface of the U-shaped block 410 is slidably connected to the inner wall of the mounting groove 210. The surface of the ventilation panel 400 is in contact with the inner wall of the U-shaped block 410. The ventilation panel 400 and the U-shaped block 410 are installed by bolts and nuts.

[0037] In this embodiment, the base 100 is made of concrete and has a convex design. The base 100 has a water tank inside and a water injection hole connected to the water tank at the top. The weight of the base 100 is increased by injecting water into the water tank. This method is the same as in the original solution and will not be described in detail.

[0038] Threaded holes are provided on both sides of the top of the base 100. When installing the two columns 200 and the base 100, the bottom end of the column 200 fits against the top end of the base 100, and the column 200 and the base 100 are fixed by bolts and threads in the threaded holes. After the two columns 200 and the base 100 are fixed, the mounting grooves 210 opened on the two columns 200 are located on opposite sides of the two columns 200.

[0039] Mounting holes are provided at the lower and upper ends of the inner walls of the two uprights 200 and on both sides of the inner wall of the crossbar 300. When installing the two uprights 200 and the crossbar 300, bolts are used to pass through the mounting holes of the crossbar 300 and the uprights 200 in sequence, and nuts are used to connect the bolts with threads for fixation. A sealing plate is fixedly connected to the upper end of the inner wall of the U-shaped groove 310 of the crossbar 300 installed above the two uprights 200, and the sealing plate seals the top of the mounting groove 210 of the two uprights 200.

[0040] When the U-shaped block 410 is inserted into the mounting groove 210, the surface of the U-shaped block 410 fits against the inner wall of the mounting groove 210. Mounting holes are provided on both sides of the surface of the U-shaped block 410 and the inner wall of the ventilation plate 400. Before transporting multiple ventilation plates 400 to the construction site, the ventilation plate 400 and the U-shaped blocks 410 on both sides are installed. During installation, one end of the bolt is passed through the mounting hole of the U-shaped block 410 and the mounting hole of the ventilation plate 400 in sequence, and then fixed by connecting the nut and the bolt.

[0041] like Figure 5 and Figure 6 As shown, a movable plate 220 is slidably connected to the inner wall of one of the columns 200, and a threaded rod 240 is rotatably connected to the lower end of the inner wall of another column 200. The lower end of the inner wall of the movable plate 220 is threadedly connected to the surface of the threaded rod 240. Multiple locking blocks 230 are fixedly connected to the side of the movable plate 220 near the mounting groove 210. A locking hole 411 is provided on the side of one of the U-shaped blocks 410 away from the ventilation plate 400. The end of the locking block 230 away from the movable plate 220 is bent into an arc shape, and the shape of the locking hole 411 matches the shape of the locking block 230.

[0042] In this embodiment, the inner wall of one of the columns 200 is provided with a moving groove that matches the moving plate 220. The ends of the multiple locking blocks 230 away from the moving plate 220 pass through the mounting groove 210. In the initial state, the ends of the multiple locking blocks 230 away from the moving plate 220 are on the same vertical plane as one side of the inner wall of the mounting groove 210. The number of the multiple locking blocks 230 is the same as the number of the multiple ventilation plates 400.

[0043] like Figure 4 As shown, multiple springs 510 are fixedly connected to both sides of the wind deflector 500, and a protective plate 511 is fixedly connected to the other end of the spring 510.

[0044] In this embodiment, in the initial state, the spring 510 is in the released state, and there is a certain distance between the protective plate 511 near the U-shaped block 410 and the U-shaped block 410. The protective plate 511 near the U-shaped block 410 moves away from the U-shaped block 410 during use. Therefore, the protective plate 511 and the U-shaped block 410 do not affect each other during use after the device is installed.

[0045] After the device is installed and in use, when the wind acts on the protective plate 511 and is discharged through the ventilation plate 400 by the guide of the protective plate 511, the protective plate 511 will squeeze the spring 510 under the action of the wind and move towards the wind deflector 500.

[0046] like Figure 4 As shown, the top and bottom of the protective plate 511 are rotatably connected to round rods 512, and the surface of the upper round rod 512 is in contact with the bottom of the ventilation plate 400.

[0047] In this embodiment, after multiple ventilation panels 400 and columns 200 are installed, the surface of the round rod 512 below the protective plate 511 contacts the top of the ventilation panel 400 below.

[0048] like Figure 3 and Figure 4 As shown, a baffle 412 is fixedly connected to the bottom end of the U-shaped block 410, and the surface of the baffle 412 is slidably connected to the inner wall of the mounting groove 210.

[0049] In this embodiment, when the U-shaped block 410 is installed with the mounting groove 210, the surface of the baffle 412 is in contact with the inner wall of the mounting groove 210. After the multiple ventilation plates 400 and the column 200 are installed, the bottom end of the baffle 412 contacts the top end of the corresponding lower U-shaped block 410, so that after the multiple U-shaped blocks 410 are connected with the mounting groove 210, the multiple baffles 412 seal the exposed mounting groove 210.

[0050] like Figure 6 As shown, a groove 250 is provided at the lower end of the other side of one of the columns 200, and the end of the threaded rod 240 away from the mounting groove 210 passes through the groove 250 and is fixedly connected to a knob.

[0051] In this embodiment, multiple protrusions are fixedly connected to the surface of the knob. The surface of the protrusions is curved into an arc. The operator can rotate the threaded rod 240 by turning the knob.

[0052] Working principle: The base 100, two uprights 200, two crossbars 300, and multiple ventilation panels 400 and corresponding windbreaks 500 are transported to the construction site for installation. During installation, first install the two uprights 200 and one of the crossbars 300. Insert the two uprights 200 into the U-shaped grooves 310 and engage them. Then move the crossbar 300 downwards to the bottom and use bolts and nuts to fix the crossbar 300 to the uprights 200. Then, install the two uprights 200... The ventilation panels 400 are installed to the base 100 via bolts and threaded holes. After this operation, multiple ventilation panels 400 and two columns 200 are installed. During installation, the U-shaped blocks 410 installed on both sides of the ventilation panel 400 are inserted into the mounting groove 210 from the top of the column 200, causing the ventilation panel 400 to move downwards. When the ventilation panel 400 can no longer move downwards, the U-shaped blocks 410 installed on both sides of another ventilation panel 400 are inserted into the mounting groove 210 from the top of the column 200. After being placed in, the U-shaped block 410 continues to move downwards. When it can no longer move downwards, the bottom end of the lower baffle plate 500 of the ventilation plate 400 contacts the top end of the lower ventilation plate 400, and the bottom end of the baffle plate 500 is away from the top end of the lower baffle plate 500. The installation position of the U-shaped block 410 and the ventilation plate 400 is between the baffle plate 500 and the lower baffle plate 500. Following the above installation method, the U-shaped blocks 410 on both sides of the ventilation plate 400 are sequentially placed into the installation groove 210 for installation. Multiple ventilation panels 400 and corresponding windbreak panels 500 form a whole, and multiple locking blocks 230 and multiple locking holes 411 correspond one-to-one on the horizontal plane. At this time, another horizontal bar 300 is inserted from the top of the two columns 200 and installed with the two columns 200 by bolts and nuts, thereby forming a enclosure. After installation, the threaded rod 240 is rotated to make the moving plate 220 drive the multiple locking blocks 230 into the locking holes 411 and engage with the locking holes 411, thereby reinforcing the multiple U-shaped blocks 410.

[0053] If the ventilation plate 400 or the wind baffle 500 is damaged during use, the installation of the corresponding ventilation plate 400 and U-shaped block 410 can be removed by bolts and nuts. After removal, the ventilation plate 400 can be moved horizontally to remove the ventilation plate 400 and the corresponding wind baffle 500 for replacement.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
