Abstract

The utility model discloses a device capable of adjusting height of a highway guardrail. The device comprises a steel pipe with one closed end and one open end, wherein the pipe body of the steel pipe is provided with at least two rows of screw perforations, the perforations on each row are corresponding, four perforations are arranged from a first row of the closed end of the pipe body, every two perforations are corresponding and are mutually and vertically distributed with the other two corresponding holes, from the perforations in the second row, two perforations are mutually corresponding in the perforations in each row, the perforations in the lower row and the perforations in the upper row are mutually and vertically distributed and are sequentially arranged, the outer diameter of an opening end of the pipe body is welded with a steel jacket, and the pipe body is provided with at least one screw hole provided with a screw thread and is screwed with a screw. The device capable of adjusting height of a highway guardrail disclosed by the utility model can increase the height of a guardrail for multiple times under the condition that the original fixed upright dose not move, and a protection function of the guardrail is fully played.

Description

A kind of device of scalable freeway guardrail height

Technical field

The utility model relates to a kind of device of scalable freeway guardrail height.

Background technology:

No matter be domestic or external, it all is fixed that speedway is reviewed one's lessons by oneself the Jianshi guardrail, but As time goes on; The highway pavement damage is serious day by day, and the road surface is increased inevitable, and this just causes the relative reduction of guardrail; The defencive function of guardrail is had a greatly reduced quality; For this reason, then should improve the height of guardrail, give full play to the defencive function of guardrail.

Summary of the invention:

The utility model has solved the deficiency that exists in the prior art, and a kind of device that can regulate the freeway guardrail height is provided, and can to greatest extent under the prerequisite of practicing thrift human and material resources, financial resources, guarantee giving full play to of freeway guardrail function.

The technical scheme that the utility model adopted is, a kind of device that can regulate guardrail height is characterized in that, comprises end sealing, the steel pipe of other end opening, and said steel pipe can be enclosed within on the cylinder of vertical columns.

Have at least two row's screw perforations on the said steel pipe body, the hole on every row is corresponding.

The said body blind end beginning first, row had four perforation, and per two holes are corresponding, and with other two orthogonal distributions of corresponding aperture; Said second round beginning, every round has two, whenever next round and the orthogonal distribution of a last round; Be arranged in order; Such arrangement not only can make the adjusting of guardrail more meet the height standard, and can make steel pipe have anti-destructive power more.

Weld steel bushing on the said steel pipe openend external diameter, to strengthen the tearing toughness of body openend.

Have the screw hole of at least one band screw thread on the said steel pipe body, and be screwed with screw,, make steel pipe be fixed on not parallel rocking on the vertical columns through tighten the screws.

Description of drawings:

Fig. 1 is a vertical columns structural representation original on the speedway.

Structural representation when Fig. 2 implements for the utility model.

Fig. 3 is the structural representation of the utility model.

Among the figure: the sealing of 1 vertical columns, 2 screw perforations, 3 screws, 4 one ends, steel pipe 5 screws 6 steel bushings of other end opening

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further, but not as the qualification to the utility model.

Referring to Fig. 1; This column is to build the speedway vertical columns 1 of beginning certainly, and its characteristic is to have corresponding screw perforation 2 on the vertical columns 1 upper end body; 2 penetrate screw 3 through boring a hole; Fix guardrail and vertical columns 1, thus guardrail, vertical columns 1 is integrated, thus the defencive function of performance guardrail.

Referring to Fig. 2: be inserted in the steel pipe 4 of end sealing on the cylinder of vertical columns 1, steel pipe 4 blind ends beginning first row's perforation 2 penetrates screw 3 and fixes with each other with guardrail, then, again according to guardrail the requirement that should heighten; Select following certain row's perforation 2 to penetrate screw 3 and fix, like this, guardrail has just been heightened as requested; Then, tighten the screw 5 on the body again, make steel pipe 4 fix not parallel rocking; Like this, just that guardrail, steel pipe 4 and vertical columns 1 is integrated, thus give full play to the defencive function of guardrail; In future,, can move to following certain row perforation again and intert, tighten descending to arrange screw like increasing once more of road surface; Can accomplish heightening once more of guardrail, thereby under the prerequisite of saving human and material resources, financial resources, give full play to the defencive function of guardrail.

Referring to Fig. 3, have at least one row's perforation 2 on the steel pipe 4 of end sealing, an end opening, have the screw hole of at least one band screw thread on the body 4, and be screwed with screw 5, welding steel bushing 6 on the body 4 openend external diameters is to strengthen the tearing toughness of body 4 openends.

Above-described embodiment, the utility model specific embodiment a kind of more preferably just, common variation that those skilled in the art carries out in the utility model technical scheme scope and replacement all should be included in the protection domain of the utility model.

Claims

1. a device of regulating the freeway guardrail height is characterized in that end sealing, the steel pipe of other end opening; Have at least two row's screw perforations on the said steel pipe body, the hole on every row is corresponding; The said body blind end beginning first, row had four perforation, and per two holes are corresponding, and with other two orthogonal distributions of corresponding aperture, said second round beginning, every round has two, and is corresponding each other, every round and the orthogonal distribution of last round down are arranged in order; Weld steel bushing on the said steel pipe openend external diameter; Have the screw hole of at least one band screw thread on the said steel pipe body, and be screwed with screw.
