Description
Technical field
The utility model relates to a kind of high-grade highway median opening place movable rail that is applicable to.
Background technology
The high-grade highway median opening is to handle vehicle for traffic accident, the interim facility of opening clearance when ambulance vehicles in case of emergency pass through with side construction of the highway sealing.The median opening movable rail under normal circumstances requires to have certain isolation, crashworthiness, should be able to be fast when interim open, flexible movement.The existing movable rail of China mostly is plug-in, and telescopic and water-filling fills the sand formula, and it does not possess the crashproof requirement of regulation.Some place is in order to guarantee the crashproof ability of opening part, original movable rail is removed, changing corrugated beam barrier is closed, perhaps set up wave beams in former plug-in movable rail both sides, adding concrete guardrail between perhaps in two row's plug-in movable rails is strengthened, but so movable rail has lost its function of easily opening again, makes the high-grade highway opening part lose its due effect.Simultaneously, existing movable rail is not tight with being connected of median strip, does not have guidance capability, has formed the hidden danger of security protection.
China's utility model patent 03249189.1 discloses a kind of speedway truss-like movable rail, certain crashproof and guidance capability is arranged, but still following shortcoming is arranged: framework does not have merogenesis, and it is whole mobile to open the back guardrail, needs to double the length of urgent breach on moving direction; The middle part of movable rail does not have column, and the collision back easily produces big displacement, causes second accident.China's utility model patent 03249192.1 discloses a kind of speedway steel pipe prestressing force cable type movable rail, also has certain crashproof and guidance capability, but has above-mentioned shortcoming equally.Simultaneously, above-mentioned two kinds of crashproof movable rails divide the band opening part bigger highway section because the middle part does not have column in the incompatibility speedway, have reached more than 40 meters as the opening part length of some speedways.In addition, the domestic patented technology that also has many about movable rail at present, but angle designs these patent major parts from opening easily, and the partial monopoly technology has been considered crashproof demand, still do not adopted the requirement of the technical standard " freeway guardrail security performance evaluation criterion " of Ministry of Communications's promulgation in 2004 that crashworthiness is carried out analytic demonstration.In a word, up to the present, do not have as yet at home simultaneously satisfy open convenient, handsome in appearance and anti-collision level can reach the median barrier that Ministry of Communications's " highway traffic safety facilities design standard " stipulates highest ranking SAm level, can with the close-connected movable rail in median strip.
The utility model content
The purpose of this utility model is to provide a kind of frame type crashproof movable rail, it can overcome the defective of available frame movable rail, guaranteeing to open easily under the prerequisite, also satisfy following requirement: the one, anti-collision level reaches the SAm level of Ministry of Communications's " highway traffic safety facilities design standard " regulation, fill the domestic gaps, and under this degree of protection required, the security performance of movable rail satisfied the requirement of " freeway guardrail security performance evaluation criterion "; The 2nd, the movable rail end can closely be connected with median barrier, the leak on not having to connect, and have guide function; The 3rd, the outward appearance of movable rail and shape can be adjusted according to the profile of normal reach guardrail before and after the movable rail, the coordination of assurance profile and attractive in appearance.
The crashproof movable rail of frame type of the present utility model is connected to form the guardrail main body by number joint frame construction, under the frame construction castor is housed, and described frame construction is made up of many crossbeams, is multi-layer multi-row and distributes, and is connected by cross bar, montant or brace between the crossbeam; Frame construction detachably flexibly connects by connector and column, detachably flexibly connects between column and the road bed; The frame construction outside is equipped with decoration panel.
Connector between above-mentioned described frame construction and the column can be a bolt, removably connects by connecting bolt between adjacent two frame constructions and the column.
Can be provided with on the cross bar of above-mentioned described frame construction end and reserve ring, the staggered up and down butt joint of the reservation ring on the adjacent two frame construction cross bars, column passes the reservation ring of adjacent butt joint, removably connects by connecting bolt between adjacent two frame constructions and the column.
Above-mentioned described column can be that anchor bolt is connected with the mode of removably connecting of road bed.
Above-mentioned described column bottom can also place the built-in fitting of road bed, and built-in fitting is the preformed hole that has clamping device that is arranged in the road bed, and the column bottom is provided with the rotating disk corresponding with preformed hole.
The outer slope form of described decoration panel is one of them of single sloping type, F type, New Jersey's type, straight wall type, reinforced, double wave ellbeam or three wave beams, also can be adjusted into other shapes according to the opening part successively external surface shape of normal reach guardrail.
The material of described decoration panel is metal sheet roof covering, plastic plate or glass epoxy.
Castor is housed below the framework, it can be moved flexibly, the framework of fractionation can be used as the interim guiding facility that directs traffic.Adopt the theft-proof type bolt to connect between the framework,, taken into account theftproof performance being held open easily simultaneously.Mounted movable rail flexibly connects by column and road bed.The two ends of movable rail are connected with the guardrail end of normal reach.Owing to adopt the structure of frame construction and column cooperative bearing, make the crashproof ability of movable rail be up to the SAm level, and effectively controlled the lateral displacement of movable rail when being subjected to vehicle collision; The guardrail profile of the decoration panel of movable rail and front and back normal reach is consistent, has not only improved the overall appearance effect of middle branch band guardrail, also can possess good guidance capability.Adopt the decoration panel of metal sheet roof covering, have certain ability of bearing crashproof load simultaneously.
