Description
Technical field
The utility model relates to traffic safety equipment, relates in particular to the flexible safety fence termination and has the flexible safety fence of this termination.
Background technology
Guardrail is to ensure one of traffic safety " passive type protection " key facility, can be divided into rigidity, semi-rigid and flexible three kinds of guardrail forms according to the deformation extent after the collision.And flexible safety fence is a kind of namely to effectively protection and to the safer protective equipment of personnel of accident vehicle, in the west such as more than 30 countries and regions such as Britain, the U.S., Australia obtained extensive use, vehicle and occupant are formed good protection.
The eighties of last century the nineties is closed peaceful (Hefei is to Nanjing) and is also once used for reference the product information of Japan, the U.S. at a high speed and tried out this kind guardrail form, and ground such as Anhui, Hubei, Beijing and Jiangsu are also attempted using among a small circle subsequently.But because the domestic strength that do not drop into was carried out special project research to the protective mechanism of flexible cable guardrail at that time, whole transportation industry also rests on eighties of last century to its cognitive level, be typically the most: the cable guardrail related specifications requirement of the recommendatory industry standard of Ministry of Communications " highway traffic safety facilities design detailed rules and regulations " (JTG/T D81-2006) that on September 1st, 2006 implemented, just directly prolong and drawn " expressway traffic safety facilities design and construction technical specification " (JTJ 074-94) related content.
External flexible cable guardrail is patented product, and traffic composition situation, condition of road surface, driveship, vehicle performance, the road management level of external highway and highway in China also are not quite similar, so can't indiscriminately imitate usefulness.And domestic also not carrying out in this respect really furtherd investigate and also do not had to such an extent that appear constructive achievement, therefore, still do not have the flexible protective mechanism system that really can adapt to the highway in China traffic characteristics at present.
Flexible safety fence mainly is made up of column, cable wire and termination, cable wire is set up on the column, two ends apply certain pulling force by the termination, after flexible safety fence is installed, the termination at two ends will be born bigger pulling force for a long time, make the prefastening force stable for extended periods of time of cable wire, then require the termination under the situation of bearing big pulling force for a long time, can keep enough stability; The moment that is bumping; the stressed of termination will increase in moment; make the moment flexible safety fence that collision takes place really to bring into play protective effect; then require the termination to have enough rigidity; flexural deformation or fracture when preventing that its stressed moment from increasing; this shows that the stability of termination and rigidity are the key factors that determines whole flexible safety fence performance.
