Abstract
The invention relates to an elastic obstruction block of a highway barrier, comprising a large arc shrapnel, a small arc shrapnel, bolts, nuts and washers, wherein the large arc shrapnel is connected with an upright column, both ends of the small arc shrapnel are connected with the large arc shrapnel through the bolts, the nuts and the washers, and the middle part of the small arc shrapnel is connected with a barrier corrugated plate through the bolts. Compared with the traditional obstruction block, in the invention, materials and a structure are greatly improved, the connecting size of the obstruction block and the barrier corrugated plate is not changed, the shrapnel accords with relevant national and international standards, the use performance of the obstruction block is improved, and the running safety can be efficiently enhanced. The elastic obstruction block has the advantages of strong shock resistance, favorable deformation effect and long service life.
Description
Technical field
The present invention relates to a kind of elastic obstruction block of highway barrier.
Background technology
Express-way guard-rail plates is most important traffic infrastructure, is important maintenance of speedway and safety guarantee facility.China's speedway grew up from the eighties, and it plays the significant effects effect to the development of national economy and society.An obstruction block is arranged between express-way guard-rail plates and the fence upright; the effect that it not only plays support, connects, if vehicle knocks guardrail board accidentally, obstruction block can also play the effect of buffering; reduce the dynamics that vehicle is hit, protect vehicle and driver's safety to a certain extent.
At present, employed highway barrier obstruction block on the highway, JT/T 281-1995 and JTJ04 standard code have two kinds of form of structure, and the A model specification that is used with steel pipe post is of a size of 17178X200X3, and the Type B specification that is used with the channel-section steel column is 200X200X3.Its shape of cross section except that with the column connection place, its overall structure is shaped as a hexagon, promptly is a rigid structure in other words.Traffic accident takes place on highway, and when automobile and guardrail bumped against, automobile was to bump against with a rigid body, only depends on guardrail, column and obstruction block to be out of shape and absorbs energy, and impact is big, occurs personal injury and automobile easily and damages.
Summary of the invention
Purpose of the present invention just provides a kind of elastic obstruction block, when automobile and guardrail collision, and obstruction block generation elastic deformation energy-absorbing, thus reduce impact force, reduce the probability that personal injury and automobile damage.
Technical scheme of the present invention realizes by following approach, it is made up of big arc spring lamination, little arc spring lamination, bolt, nut, packing ring, wherein big arc spring lamination is connected with column, the both ends of little arc spring lamination are connected with big arc spring lamination by bolt, nuts and washers, and the middle part of little arc spring lamination is connected by bolt with the guardrail corrugated sheet.
The obstruction block that the present invention is more traditional is compared, material and structure have been carried out bigger improvement, do not change the connection dimension of obstruction block and guardrail corrugated sheet, and spring leaf meets relevant country, international standard, improve the functional performance of obstruction block, can improve security of operation effectively.This elastic obstruction block impact resistance is big, and deformation effect is good, long service life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Wherein: the big arc spring lamination of 1-, the little arc spring lamination of 2-, 3-bolt, 4-nut, 5-packing ring, 6-column, 7-guardrail corrugated sheet
The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
The present invention is made up of big arc spring lamination 1, little arc spring lamination 2, bolt 3, nut 4, packing ring 5, wherein, big arc spring lamination 1 is connected with column 6 and contacts the certain initial pressure of generation with guardrail corrugated sheet 7, the both ends of little arc spring lamination 2 are connected with big arc spring lamination 1 by bolt 3, nut 4 and packing ring 5, when being hit, its shell fragment distortion can be moved along the guide groove in the big arc spring lamination, reach the purpose that absorbs impact energy, the middle part of little arc spring lamination 2 is connected by bolt 3 with guardrail corrugated sheet 7, plays fixation.
Big arc spring lamination and little arc spring lamination produce elastic deformation and absorb a large amount of impact energys when being subjected to impacting, being in contact with one another between them produces friction can further absorb impact energy; And arc spring lamination contacts withstand shocks also generation friction and absorption energy with the guardrail corrugated sheet greatly.
Large and small arc spring lamination all adopts the better and bigger engineering material of modulus of elasticity of elasticity, and the material of elastic obstruction block can adopt 60Si2Mn, also can adopt 65Mn.The present invention adopts 60Si2Mn.
Elastic obstruction block assembly size need meet country, the international standard of relevant highway design, to guarantee the requirement of obstruction block interchangeability size conforms the countries concerned, international road standard.
