Description
Technical field
The utility model relates to a kind of freeway guardrail post device, and it is applicable in the divided shielding in speedway track, is mainly used to the mid portion of nonfloating rail plate.
Background technology
In the prior art, the divided shielding in speedway track is realized by guardrail board; Because the length of guardrail board is longer, intermediate demand supports by post and fixes; For this reason, the post structure Design just is related to the result of use and the intensity of guardrail integral body.
China Patent No. 92213037X discloses the utility model patent that a kind of name is called " highway W waveform erosion control guardrail ", and the W waveform erosion control guardrail board that it has a different cross section size by two ends is successively with the screw overlap joint and be fixed on the column of road.Because the guardrail board of this utility model patent is directly fixed on the column with screw, its impact resistance is bad, and the safety of use is not high; Simultaneously, it is base material that plate body neither adopt polyvinyl chloride resin, so its easy oxidation and rusting damages automobile easily during collision.
China Patent No. 200820157983X discloses the utility model patent that a kind of name is called " speedway anticollision barrier ", it connects corrugated sheet and column with the U-shaped spring, when the Vehicular impact corrugated sheet, the U-shaped reed has the better elastic impact, has reduced the damage of vehicle.Although this structure is more much better with the structure that screw is directly fixed on the column than guardrail board, in actual use, this structure only is applicable to the steel guardrail, can not be used for the PVC guardrail board.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design, the effective freeway guardrail of nonfloating rail post device are provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this freeway guardrail comprises at least one cylinder and guardrail board with the post device, guardrail board is positioned at the middle and upper part of cylinder, it is characterized in that: between described cylinder and guardrail board, also be provided with carriage, described carriage and cylinder are fixed, and guardrail board and carriage are fixed; Bolt by frame construction between described guardrail board and the carriage; Described guardrail board is made with polyvinyl chloride resin.Make that thus structure design of the present utility model is more reasonable, impact resistance is better, and the safety of use is higher; Guardrail board is made with polyvinyl chloride resin, need not to carry out processing such as anticorrosion, spraying aborning, has really realized environmental protection; Simultaneously, because the proportion of polyvinyl chloride resin is significantly less than steel, its integrated cost is low.
As preferably, its two ends of the bolt of described frame construction are provided with external screw thread, and this bolt is an integral structure, is coated with guardrail board in the frame construction of this bolt; Make that the structure design of bolt is more reasonable, bonding strength is better, and its result of use of the guardrail board that is coated is better.
As preferably, described bolt is coated with guardrail board between frame construction and carriage, makes fixing more reasonable between guardrail board and the carriage, and intensity is better.
As preferably, on two planes of symmetry of described carriage, have cylinder fixing hole and guardrail board fixing hole, the two ends coupling of described guardrail board fixing hole and described bolt makes that the structure design of carriage is more reasonable, can connect cylinder and guardrail board easily.
As preferably, two plane of symmetry indents of described carriage so that be connected and fixed with cylinder and guardrail board attractive in appearancely, and can better reach bonding strength, and safety in utilization is higher.
The utility model compared with prior art, have the following advantages and effect: overall construction design is reasonable, shock resistance is good, cost is low, long service life; Have good resiliency during vehicle collision, be difficult for the scratch automobile during collision, and greatly reduced the secondary injury of people's car; Simultaneously, the material environmentally safe of use, environmental protection belongs to the product that country should actively promote.

The specific embodiment
Embodiment 1:
Referring to Fig. 1-Fig. 8, this is that the utility model adopts two guardrail board and guardrail board to be provided with the embodiment of projection.
The utility model mainly is made up of cylinder 1, guardrail board 2 and carriage 3, and guardrail board 2 is positioned at the middle and upper part of cylinder 1, and carriage 3 is arranged between cylinder 1 and the guardrail board 2, and is fixing by plain bolt 5 between carriage 3 and the cylinder 1; Bolt 4 by frame construction 41 between guardrail board 2 and the carriage 3 is fixing; Guardrail board 2 usefulness polyvinyl chloride resins are made.
In the present embodiment, adopted two guardrail board 2, and used two carriages 3, wherein: can be fixed together between bracket 301 and the bottom bracket 302; Usually, the thickness of bottom bracket 302 is littler than the thickness h of bracket 301, so that play better cushioning effect when vehicle collision; Here said thickness H, h are seen as the distance of the external surface of bracket 301, bottom bracket 302 to cylinder 1 external surface from Fig. 2.Certainly, the thickness of bottom bracket and bracket also can be identical.
