Description
Technical field
The utility model relates to highway traffic safety facility field, particularly relates to the plug-in movable rail that a kind of Expressway Central Strip opening part arranges.
Background technology
Movable rail is mainly arranged at Expressway Central Strip opening part position, for preventing vehicle turning around arbitrarily on speedway, affects vehicle pass-through, cause traffic accident, in emergency situation, can also open fast, for passing through of emergency management and rescue vehicle temporarily; But movable rail, as the part in the anticollision barrier system of median strip, also should require it to possess enough crashproof abilities, to prevent pouring subtend track when errant vehicle from clashing into, cause pernicious traffic accident.
At present, in the industry design specifications of China, proposed, at central separating belt opening place, plug-in movable rail is set, therefore, the plug-in movable rail all adopting in existing Expressway Central Strip opening part major part, this movable rail mainly adopts steel pipe welding to be connected into " opening " character form structure, inserts and stands on road surface.Practice shows, this plug-in movable rail structure does not possess crashproof ability, even if this plug-in movable rail of minibus collision out of control all easily thrusts guardrail and enters subtend track, has serious potential safety hazard.Along with going deep into and development of safety of China facility research, China has developed a series of anti-collision movable guardrail, can effectively eliminate the potential safety hazard of central separating belt opening place, based on this technological progress, speedway related management department also progressively existing plug-in movable rail is being carried out to upgrading, the major way of its transformation, for original plug-in movable rail is removed, is changed by the Novel crashproof movable rail that possesses crashproof ability.But because the built speedway of China has reached 100,000 kilometers more than, by the every 2 kilometers basic principles that the movable rail at 30 meters, a place is set, calculate, in upgrading process, need altogether the plug-in movable rail total length of removing will reach 1500 kms, every meter of plug-in movable rail calculates by the steel weight of 20 kilograms, and the mode of this upgrading will cause the waste of 30000 tons of steel.
In sum, at present in the urgent need to developing a kind of reinforcement structure that can improve the crashproof ability of plug-in movable rail, to meet the upgrading of speedway plug-in movable rail, when improving the crashproof ability of plug-in movable rail, can farthest to existing plug-in movable rail member, recycle, save improvement cost.
Utility model content
The purpose of this utility model is to provide a kind of reinforced plug-in movable rail, to improve the crashproof ability of existing plug-in movable rail structure, meet the upgrading of existing plug-in movable rail, can farthest to existing plug-in movable rail member, recycle, save improvement cost simultaneously.
For realizing above-mentioned target, the utility model adopts following technical scheme: the utility model comprises end support shelves, pipe rope framed bent unit, junction plate, latch, pretension bar and clamp nut, pipe rope framed bent unit is comprised of steel pipe framed bent, cable wire, connector, ground tackle, steel pipe framed bent is supported and is " opening " font formation by longitudinal steel pipe, supporting leg, vertical supporting and vertical arc, longitudinally the two ends of steel pipe arrange respectively connector, cable wire is arranged in longitudinal steel pipe, and adopts ground tackle to carry out pretension anchoring in connector position.
Described cable wire can be one of them of wire rope, steel strand.
Described ground tackle can be one of them or combination of Extrusion anchor ground tackle, intermediate plate ground tackle, screw thread ground tackle.
Described connector can be one of them or combination of board-like, tubular type, ring type, and the mode of moulding can adopt one of them or combination of monoblock cast, welding.
The cross sectional shape that longitudinal steel pipe of described steel pipe framed bent, supporting leg, vertical supporting and vertical arc support can be one of them of circular, oval, rectangle.
Described pretension bar consists of round steel pipe, connector and screw thread, and connector and screw thread are arranged at respectively the two ends of round steel pipe.
Described end support shelves is by column, diagonal brace and support and be welded, and column, diagonal brace and the cross sectional shape that supports can be one of them of circle, rectangle, flute profile.
