Abstract

The utility model discloses a design structure of a highway isolating guard fence which is formed by the connection of sectional steel upright posts with concave sections, and supporting rod braiding net sheets. The upright posts of the isolating guard fence dispense with punching holes and hooks and inclined supports and have the advantage of convenient, flexible and firm connection so that the utility model is a highway isolating guard fence with simple structure, convenient installation and beautiful design.

Description

Highway isolating guard fence

The utility model relates to the structure design category of speedway gauze wire cloth isolated gate.

For avoiding people, animal to cross express highway pavement, guarantee the safety of turnpike driving, the gauze wire cloth isolated gate is all installed in the outside at speedway both sides anticollision barrier, and this isolated gate generally is made up of column, gauze wire cloth, bearing diagonal, connector and silk screen tensioning apparatus.(be generally 2m) across a certain distance mutually, column is fixed on the ground, location with concrete (9) casting, goes out the gauze wire cloth hook on the column at a certain distance, and gauze wire cloth strikes back hook after hanging thereon again, and gauze wire cloth just is fixed on the column.For preventing that column from tilting and the globality of raising isolated gate, (be generally 100m) at a certain distance, additional one group of bearing diagonal on the column of spaced points.For making gauze wire cloth smooth tensioning up and down, use three tensioning steel wires usually, divide upper, middle and lower break-through gauze wire cloth, add one group of euphroe every 100m and adjust tensile force.

Existing this isolated gate, its column manufacturing process complexity, easily broken when hammering compresses after the gauze wire cloth hook linked network that punch process goes out, gauze wire cloth is hung not only but also draw, and it is wavy that last bottom still is, and is difficult in alignment.Outward appearance is not beautiful, and installs cumbersome.

The purpose of this utility model is that design is a kind of simple in structure, and column does not need towards hook, and manufacturing process is simple, gauze wire cloth highway isolated gate easy for installation.

The highway isolated gate of the utility model design mainly be by "

" the type section shaped steel column (1), strut (2), mesh grid sheet (3), "

" type compresses other hook (6), and the fastening assembly of being made up of bolt (4), rectangular nut (5) and pad (7) assembles (see figure 1).The concrete structure of realizing the isolated gate that the utility model designs is as follows:

1. "

" type section profiled bar column (1) (see figure 2)

The isolated gate column be cold roll forming " " type section steel block by certain altitude, and Yu Yiduan extrudes the inclination angle.

2. strut mesh grid chip architecture (see figure 8)

Strut mesh grid sheet is combined by strut (2) and mesh grid sheet (3).Two ends and tilting position are respectively worn the steel pipe strut that two ends flattened and dashed the about 20mm of diameter that slotted hole is arranged about the mesh grid sheet, and the steel pipe strut also can be pressed into elliptic jet to improve the rigidity on the main stress direction.The available welded wire fabric sheet of strut mesh grid sheet (see figure 9) replaces.

Bolt (4), rectangular nut (5), strut (2) with "

" type section profiled bar column (1) syndeton (see figure 3).

Bolt (4) pass strut (2) one end slotted holes and column " " rectangular nut (5) in locating is fixedly connected.

4. "

" type compress other hook (6), strut mesh grid sheet with "

" type section profiled bar column (1) syndeton (seeing Fig. 4, Fig. 5).

Strut mesh grid sheet or welded wire fabric sheet except that key positions such as end are connected and fixed with bolt (4), rectangular nut (5), pad (7) fastening assembly and column, other general place can any part of column be shaped as "

" to compress other hook (6) fixing for type, earlier with "

" type compresses other rhampotheca and lives mesh grid sheet (or welded wire fabric sheet), will compress again other hook be pressed into column "

" locate in.Mesh grid sheet steel wire is out of shape to column one lateral bending song because of pressurized, pressure relief when compressing two fastener posture in standing (qigong) posts of other hook, and pressure hook just is anchored on the mesh grid sheet on the column under the bounce effect of steel wire.

Bolt, rectangular nut, pad, welded wire fabric sheet with " " type section profiled bar upright post connection structure (seeing Fig. 6, Fig. 7).

Bolt pass pad, welded wire fabric sheet and column "

" rectangular nut in locating is fixedly connected.

Realize that best design of the present utility model is:

Isolated gate column usefulness "

" the type section profiled bar blocks by certain altitude, and Yu Yiduan extrudes the inclination angle.Be that up and down two ends and tilting position are respectively worn two ends and flattened and dash the steel pipe strut that slotted hole is arranged at the mesh grid sheet with strut mesh grid sheet, strut mesh grid sheet between column.Strut mesh grid sheet be with bolt pass strut one end slotted hole and column "

" rectangular nut in locating links to each other, be shaped as "

" type compresses other rhampotheca and lives the mesh grid sheet, will compress again other hook be pressed into column "

" fixedly form in locating.The available welded wire fabric sheet of strut mesh grid sheet replaces.

The isolation railings for road of the utility model design has been compared following advantage with the existing highway isolated gate:

1. column does not need the punched hole punching hook, good manufacturability, and strut pieces of fabric net and column are connected and fixed very convenient, flexible and firm.

2. strut can be straightly with mesh grid sheet stretching, after installing the isolated gate total length up and down along in line, neat appearance.

3. the strut two ends are fixed on the column, make to form a sealing rigid body between column, and the isolated gate globality is strong, can save the side direction bearing diagonal.

4. simple in structure, easy for installation, cost significantly reduces.
