Technical Field

[0001] The utility model belongs to the technical field of connecting columns, in particular to a composite guardrail net connecting column. Background Art

[0002] In order to prevent people and animals from entering, fence nets are installed on both sides of closed sections such as highways and railways. The fence net includes a mesh and a connecting column, and a hook is set on the connecting column, and the horizontal steel bars of the mesh are hung on the hook. There are mainly two types of fence net posts currently used: first, the connecting column is made of metal material, and the hook is welded on the connecting column. The column has poor corrosion resistance and short service life. In order to avoid corrosion and extend the service life, it is necessary to spray paint on the surface of the connecting column regularly, and it is easy to be stolen; second, in order to improve the corrosion resistance of the column, increase the service life of the column, and avoid theft, people use non-metallic materials with strong corrosion resistance, such as fiberglass, plastic, etc. In this way, although the above problems are solved, the impact resistance is poor and it is easy to break. In order to improve the impact resistance, the wall thickness is increased, which not only increases the material cost, but also the damaged and replaced columns are difficult to recycle materials, which is easy to cause environmental pollution. Utility Model Content

[0005] Its additional technical features are:

[0006] There are four longitudinal support ribs, and the cross-sections of the longitudinal support ribs are located at the four vertices of the rectangle;

[0007] The outer sleeve comprises a structural layer located on the inner side and an anti-aging layer located on the radial outer side of the structural layer;

[0008] The cross section of the outer sleeve is square, the side length of the cross section of the outer sleeve is 0.5-0.5m, and the overall thickness of the anti-aging layer and the structural layer is 0.6-1mm;

In an environment with large temperature differences, the separation of the steel bars and the concrete can be effectively avoided. The connecting hub is inserted into the annular groove or the spiral groove. Even if the connecting hub and the longitudinal support ribs are welded when pouring concrete, the connecting hub will not move, and the structure is more solid. Secondly, since there are four longitudinal support ribs, the cross-sections of the longitudinal support ribs are located at the four vertices of the rectangle, and the impact resistance is greater. Thirdly, since the outer sleeve includes an inner structural layer and an anti-aging layer located radially outside the structural layer, the structural layer adopts a material that focuses on impact resistance, and the anti-aging layer is added with more anti-ultraviolet and other materials, so the material cost is lower. Fourthly, since the cross-section of the outer sleeve is square, the side length of the cross-section of the outer sleeve is 0.5-0.5m, and the overall thickness of the anti-aging layer and the structural layer is 0.6-1mm. The anti-aging layer adopts PVC Material, the structural layer adopts recycled PVC material, which has strong anti-aging performance and longer service life; fifthly, since the hook includes an outer hook head, a connecting rod and an inner hook head, the inner hook head is hung on the connecting hub, and the inner hook head is hung on the connecting hub before pouring the concrete filler or after pouring and the concrete is basically solidified, the structure is more solid and the tensile strength of the hook is large; sixthly, since the hook includes an outer hook and a connecting screw, the connecting screw is embedded in the concrete filler, after the pouring is completed and the concrete is basically solidified, the connecting screw is screwed into the concrete filler and waits for it to be completely solidified, and the tensile strength of the hook is large.

[0018] The structure and use principle of the composite guardrail net connecting columns of the utility model are further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a schematic diagram of the structure of the composite guardrail net connecting column of the utility model, the composite guardrail net connecting column of the utility model comprises a column body 1 and a hook 2, the column body 1 comprises an outer sleeve 3, a filling skeleton 4 and a concrete filler 5, the filling skeleton 4 comprises a plurality of longitudinal support ribs 6 and a connecting hub 7 fixed to the longitudinal support ribs, the connecting hub 7 is a plurality of vertically spaced arrangements, annular grooves 8 or spiral grooves 9 are spaced apart on the longitudinal support ribs 6, and the connecting hub 7 is inserted into the annular groove 8 or the spiral groove 9.

[0020] The outer sleeve is provided with a filling skeleton 4 and a concrete filler 5, which improves the impact resistance of the connecting column. The outer sleeve prevents the filling skeleton and the concrete filler from being exposed to rain and sun, prolongs the service life, and improves the corrosion resistance. The longitudinal support ribs 6 are provided with annular grooves 8 or spiral grooves 9 at intervals, so that the bonding strength between the concrete and the filling skeleton is greater. In addition, since the temperature linear expansion coefficient of the steel bar is 0.12 / 10000, and the temperature linear expansion coefficient of the concrete is 0.10 / 10000. In an environment with a large temperature difference, the separation of the steel bar and the concrete can be effectively avoided. The connecting hub 7 is stuck in the annular groove 8 or the spiral groove 9. When pouring concrete, even if the connecting hub 7 and the longitudinal support rib 6 are welded, it will not cause the connecting hub to move, and the structure is more solid.

[0021] There are four longitudinal supporting ribs 6, and the cross-sections of the longitudinal supporting ribs are located at the four vertices of the rectangle, so the impact resistance is greater.

[0022] The outer sleeve 3 includes an inner structural layer 31 and an anti-aging layer 32 radially outside the structural layer 31. The structural layer 31 is made of impact-resistant materials or recycled plastics, while the anti-aging layer 32 is added with more anti-ultraviolet materials, so the material cost is lower.

[0023] The cross section of the outer sleeve 3 is square, the side length of the cross section of the outer sleeve 3 is 0.5-0.5m, and the overall thickness of the anti-aging layer and the structural layer is 0.6-1mm; the anti-aging layer adopts PVC material, and the structural layer adopts recycled PVC material, which has strong anti-aging performance and longer service life.

[0024] like Figure 1 As shown, the hook 2 includes an outer hook head 21, a connecting rod 22 and an inner hook head 23. The inner hook head 23 is hung on the connecting hub 7. Before pouring the concrete filler or after pouring and after the concrete is basically solidified, the inner hook head is hung on the connecting hub. The structure is more solid and the tensile strength of the hook is large.

[0025] like Figure 6 As shown, the hook 2 includes an outer hook 24 and a connecting screw 25. The connecting screw 25 is embedded in the concrete filler. After the concrete is poured and basically solidified, the connecting screw is screwed into the concrete filler and waits for it to solidify completely. The hook has a large tensile strength.

[0026] The protection scope of the present invention is not limited to the above-mentioned embodiments. As long as the structure is the same or similar to the structure of the composite guardrail net connecting the columns of the present invention, it falls within the protection scope of the present invention.
