Description

Technical Field

[0001] The utility model relates to the technical field of fast road enclosures, in particular to a novel isolation fence used for fast roads. Background Art

[0002] Road isolation fences are mainly used as safety protection nets on the edges of roads such as highways, expressways, and railways. That is, the expressways are separated from ordinary roads and non-motorized vehicle roads through isolation fences, thereby ensuring the safe operation of the roads.

[0003] Since highways or expressways are long, multiple fences are usually assembled during installation. In addition, some roads have corrugated guardrails at their edges, and the fences need to be installed on the corrugated guardrails for protection. At present, adjacent fences are generally directly connected by pins during installation, but the pin connection is firm and unstable, and the connection is prone to loosening under strong winds, posing a safety hazard. In addition, during later maintenance, since the pin connection is fixed, if a fence is disassembled or replaced separately, its error accuracy is required to be high, that is, errors that are too large or too small will affect the installation of the fence. Utility Model Content

[0004] The utility model aims to solve the above problems and provides a new type of isolation fence for expressways.

[0005] The utility model is realized through the following technical scheme: a new type of isolation fence for expressways, characterized in that it includes a plurality of columns, each of which is provided with a pair of fixing holes at the lower end, and bolts pass through the fixing holes to fix the columns to the corrugated guardrails, and an isolation fence is arranged between two adjacent columns, and each isolation fence is provided with a connecting piece 1 at the upper and lower ends of both sides, and the connecting piece 1 is provided with a transverse adjustment hole, and a connecting piece 2 corresponding to the connecting piece 1 is provided on the upper part of the column, and the connecting piece 2 is provided with a longitudinal adjustment hole, and bolts pass through the transverse adjustment hole and the longitudinal adjustment hole in sequence to adjust the isolation fence to the column.

[0006] Furthermore, the isolation grille can be adjusted left and right through a transverse adjustment hole.

[0007] Furthermore, the isolation grille can be adjusted up and down through a longitudinal adjustment hole.

[0008] The beneficial effects of the utility model are as follows: the utility model utilizes upright posts to fix the isolation fence on the corrugated guardrail, thereby improving the road protection effect; the isolation fence is adjusted up and down and left and right during installation by respectively cooperating with the transverse adjustment holes and the longitudinal adjustment holes, thereby reducing its error accuracy and improving the installation efficiency; at the same time, the utility model is easy to disassemble, and the space occupied is reduced after disassembly, which is more conducive to large-scale transportation by workers.

[0009] The lower part of the vertical pole of the utility model is fixed on the corrugated guardrail by bolts, so that the connection between the two is more firm and stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with embodiments.

[0016] like Figures 1 to 4 As shown, a new type of isolation fence 1 for expressway includes several columns 4, each of which is provided with a pair of fixing holes 8 at the lower end of each column 4, and bolts 7 are passed through the fixing holes 8 to fix the columns 4 to the corrugated guardrail, that is, the columns 4 are close to the crest of the corrugated guardrail and the columns 4 are fixed by bolts 7 passing through the fixing holes 8, and an isolation fence 1 is arranged between two adjacent columns 4, and connecting pieces 1 are arranged at the upper and lower ends of both sides of each isolation fence 1, a total of 4 connecting pieces 1 2, each connecting piece 1 2 is provided with a transverse adjustment hole 3, and the isolation fence 1 is adjusted left and right through the transverse adjustment hole 3, and a connecting piece 2 5 corresponding to the connecting piece 1 2 is arranged on the upper part of the column 4, that is, each connecting piece 1 2 has a corresponding connecting piece 2 5 fixed on the column 4, and the connecting piece 2 5 is provided with a longitudinal adjustment hole 6, and the isolation fence 1 is adjusted up and down through the longitudinal adjustment hole 6, and the bolts 7 pass through the transverse adjustment hole 3 and the longitudinal adjustment hole 6 in sequence to adjust the isolation fence 1 on the column 4.

[0017] When in use, the column 4 is fixed to the inner side of the corrugated guardrail by bolts 7, and then the isolation fence 1 is installed between adjacent columns 4. The isolation fence 1 can appropriately adjust the relative position of the bolts 7 and the horizontal adjustment hole 3 according to the distance between adjacent columns 4. At the same time, if the isolation fence 1 needs to be moved up or down, the bolts 7 can be loosened to adjust the installation position. When the isolation fence 1 needs to be maintained or replaced later, it can be directly disassembled.

[0018] The utility model has a wide application range, and the isolation fence 1 can be installed in a normal guardrail section, a strip-shaped basic guardrail section, and a single-column double-wave guardrail section.

[0019] Except for the technical features described in the specification, the other technical features are known to those skilled in the art.
