Abstract
Description
Technical Field
[0001] This utility model belongs to the field of boundary fence technology, and in particular relates to a boundary fence. Background Technology
[0002] Border fencing used on the borders of two countries or the dividing lines between two important locations must not only be impact-resistant but also have anti-climbing capabilities. Currently used border fencing consists of multiple framed sections. Each section comprises a mesh panel welded from warp and weft wires, with a frame positioned behind the panel. The mesh panel includes a front section, and behind it is a frame composed of vertical and horizontal support posts, both of which are solid slats. The aforementioned boundary fence has the following defects: First, the standard length and width of a shipping container are 12.032 meters and 2.352 meters respectively, while the standard boundary fence is 2.8 meters high. A single piece of fence cannot be transported in a container; it requires a container of a specific size, increasing transportation costs. Second, the solid slat frame is prone to bending when impacted on one side of the fence, and the bent slats are difficult to straighten, resulting in an uneven surface. Third, the vertical and horizontal support rods intersect in a cross shape, resulting in poor anti-climbing performance. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a boundary fence that is easy to transport in standard containers, has low transportation costs, is easy to assemble, has a high anti-climbing effect, good overall strength of the mesh, can recover under its own elasticity after being impacted, and has strong impact resistance.
[0004] To solve the above problems, the technical solution adopted by this utility model for a boundary fence is as follows: it includes a mesh sheet welded from warp and weft wires, a frame is provided behind the mesh sheet, the mesh sheet includes an upper mesh sheet and a lower mesh sheet, an upper connecting plate is provided below the upper mesh sheet, a lower connecting plate is provided above the lower mesh sheet, and a connecting bolt is provided between the upper connecting plate and the lower connecting plate. The frame includes vertical reinforcing strips located at both ends of the upper and lower connecting plates, a first stop bar intersecting the warp wires at a certain angle, and a second stop bar intersecting the first stop bar at a certain angle. The first stop bar is fixed to the vertical reinforcing strip by welding. The extension line of the first stop bar located above the upper connecting plate coincides with the corresponding first stop bar located below the lower connecting plate. The first stop bar is a hollow square tube, and the second stop bar is a strip plate.
[0005] Its additional technical features are:
[0006] The angle between the first stop bar and the warp thread is 45 degrees, and the first stop bar is perpendicular to the second stop bar.
[0007] Compared with existing technologies, the boundary fence provided by this utility model has the following advantages: Firstly, it includes a mesh sheet welded from warp and weft wires, with a frame behind the mesh sheet. The mesh sheet includes an upper mesh sheet and a lower mesh sheet. An upper connecting plate is provided below the upper mesh sheet, and a lower connecting plate is provided above the lower mesh sheet. Connecting bolts are provided between the upper and lower connecting plates. The frame includes vertical reinforcing strips at both ends of the upper and lower connecting plates, a first stop bar intersecting the warp wires at a certain angle, and a second stop bar intersecting the first stop bar at a certain angle. The first stop bar is fixed to the vertical reinforcing strip by welding. The extension line of the first stop bar above the upper connecting plate coincides with the corresponding first stop bar below the lower connecting plate. The first stop bar is a hollow square tube, and the second stop bar is a strip plate. The vertical reinforcing strips at both ends of the upper and lower connecting plates, and the first stop bar is fixed to the vertical reinforcing strip by welding. The mesh is fixed in a fixed manner, which increases the strength of the entire mesh. The height of the lower mesh is 2.23 meters, and the height of the upper mesh is 0.55 meters. Connecting bolts are installed between the upper and lower connecting plates, allowing for transportation using standard containers. After transportation to the destination, the two meshes are fixed with connecting bolts. This not only facilitates transportation but also improves the impact resistance of the entire mesh due to the transverse reinforcing bands between the meshes. The first baffle is a hollow square tube. After being impacted, the mesh is deformed first, absorbing some of the impact energy. The hollow square tube also deforms after being impacted. After the external force is removed, the deformed hollow square tube returns to its original shape under its own elasticity. The second baffle is a solid strip plate with an inclined direction, providing good anti-climbing effect. Secondly, since the angle between the first baffle and the warp wire is 45 degrees, and the first baffle is perpendicular to the second baffle, the strength and anti-climbing effect of the entire boundary fence are improved.

[0011] The structure and operating principle of a boundary fence according to this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0012] like Figure 1 , Figure 2 and Figure 3As shown in the schematic diagram, this utility model discloses a boundary fence. The boundary fence includes a mesh panel 3 welded from warp wires 1 and weft wires 2. A frame 4 is provided behind the mesh panel 3. The mesh panel 3 includes an upper mesh panel 31 and a lower mesh panel 32. An upper connecting plate 51 is provided below the upper mesh panel 31, and a lower connecting plate 52 is provided above the lower mesh panel 32. A connecting bolt 6 is provided between the upper connecting plate 51 and the lower connecting plate 52. The frame 4 includes vertical reinforcing strips 7 located at both ends of the upper connecting plate 51 and the lower connecting plate 52, a first stop bar 8 intersecting the warp wires 1 at a certain angle, and a second stop bar 9 intersecting the first stop bar at a certain angle. The first stop bar 8 is fixed to the vertical reinforcing strip 7 by welding. The extension line of the first stop bar 8 located above the upper connecting plate 51 coincides with the corresponding first stop bar located below the lower connecting plate. The first stop bar 8 is a hollow square tube, and the second stop bar 9 is a strip plate.
[0013] The vertical reinforcing strips 7 at both ends of the upper connecting plate 51 and the lower connecting plate 52, and the first stop strip 8 are fixed to the vertical reinforcing strips by welding. In this way, the strength of the entire mesh is increased. The height of the lower mesh is 2.23 meters and the height of the upper mesh is 0.55 meters. Connecting bolts 6 are set between the upper connecting plate 51 and the lower connecting plate 52, so that standard containers can be used for transportation. After transportation to the destination, the two meshes are fixed by connecting bolts 6. Not only is transportation convenient, but the horizontal reinforcing strips between the meshes also improve the impact resistance of the entire mesh. The first stop strip is a hollow square tube. After being impacted, the mesh is deformed first, consuming part of the impact energy. The hollow square tube is also deformed after being impacted. After the external force is removed, the deformed hollow square tube returns to its original shape under the action of its own elasticity. The second stop strip is a solid strip plate in the inclined direction, which has a good anti-climbing effect.
[0014] The angle between the first stop bar 8 and the warp wire 1 is 45 degrees, and the first stop bar 8 is perpendicular to the second stop bar 9. This can improve the strength and anti-climbing effect of the entire boundary fence.
[0015] The scope of protection of this utility model is not limited to the above embodiments. Any structure that is the same as or similar to the boundary fence structure of this utility model falls within the scope of protection of this utility model.
