Description
Technical field
The utility model relates to a kind of speedway and uses guard bar device, and it mainly is applicable in the divided shielding in speedway track.
Background technology
In the prior art, the divided shielding in speedway track is to lean on guardrail board to realize with being connected of column; Because the length of guardrail board is longer, the centre just needs post to support and fixes; Simultaneously, because the length of guardrail board can not endless, guardrail board needs butt joint each other, and this butt joint need connect and fix through column broad in the middle; Meanwhile, the two ends of guardrail board also need connect and fix through the big column in termination.For this reason, the design of post, the big pillar construction of column broad in the middle and termination just is related to the result of use and the intensity of whole guard bar device.
Chinese patent 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.
Chinese patent 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.
Chinese patent numbers 2010200145262 discloses the utility model patent that a kind of name is called " express highway pavement maintenance corrugated beam barrier device "; It comprises the fence upright of wave beams, obstruction block and hollow; And fence upright comprises extension pipe and inner sleeve, and extension pipe and inner sleeve all are positioned at the steel duct of fence upright.The main purpose of this structure design is for the fence upright that extends, and guardrail wherein is not to process with polyvinyl chloride resin, and the guardrail shape also only is suitable for to be had in wave beams, and is to fix through plain screw between wave beams and the obstruction block; So its integrated cost is high, uses not enough environmental protection; Simultaneously, narrow application range, impact resistance are good inadequately, and application life is lower.
In addition, also have utility model and the utility application of some other speedway, but their structure design is more unreasonable with guard bar device.Simultaneously, existing structure can not simple combination, otherwise can cause intensity poorer, perhaps causes result of use bad, perhaps causes polluting, and perhaps causes cost very high, perhaps causes and can't implement.
