Abstract

The invention discloses a kind of central guardrail of cellular obstruction block, including column, obstruction block and guardrail board, described obstruction block side is connected by the first screw assembly with guardrail board, the opposite side of described obstruction block is connected by the second screw assembly with column, described obstruction block is combined by the polygon annular solid of more than three, advantage is that the annular solid that four cross sections are hexagonal structure constitutes a cellular obstruction block, alveolate texture is the structure of full blast, can be on the premise of proof strength, farthest reduce the consumption of material, manufacturing cost is low;When guardrail board is being hit, the power that guardrail board is subject to is delivered to the first tetracyclic ring body first, power is passed to second, third and fourth annular body by the first tetracyclic ring body again, each annular solid deforms upon absorption impact, unabsorbed power is finally delivered to power post by fourth annular body, now impact has been greatly reduced, and energy-absorbing effect is good;Multiple hexagonal ring body by integral forming are set, and adjacent ring body shares a connection wall, so simple in construction, and assembling is easy.

Description

A kind of central guardrail of cellular obstruction block
Technical field
The present invention relates to a kind of central guardrail, more particularly to a kind of central guardrail of cellular obstruction block
Background technology
Now, highway, city intersection, overpass etc. are largely built, and transportation network is increasingly intensive, and the whole world Car ownership increases substantially year by year, and traffic accident incidence is therewith in ascendant trend year by year.Counted according to related data, it is average 250 times are there are about on annual every 200 meters of highways and hits central guardrail event;And this kind of event is other types on highway As many as 3 times of traffic accident, the accident that created greater casualties because guardrail is overly hard it is quite a few.Therefore, preventing from operating at a high speed The vehicle of highway goes out the track at place, and to be effectively isolated the vehicle travelled in opposite directions, a kind of energy absorption performance of design and installation is good Central guardrail have important practical significance.
Existing central guardrail includes column, obstruction block and guardrail board, and obstruction block is arranged on column, solid on the outside of obstruction block Surely there is guardrail board.China Patent No. is 201310005107.0 disclosure of the invention:A kind of good highway of energy absorption performance Guardrail, including column and the guardrail board for being arranged on column at least side, feature is that rubber is fixedly installed between column and guardrail board It is fixedly installed on cushion rubber obstruction block, column in the first contiguous block, guardrail board and is fixedly installed the second contiguous block, rubber ring is deterred First collar and second collar are provided with block, the center line of first collar and second collar along rubber ring obstruction block is symmetrically set Put, rubber ring obstruction block is fixed by first collar with the first contiguous block, rubber ring obstruction block is connected by second collar and second Block is connect to fix.The shortcoming of the invention is only to be provided with a rubber ring obstruction block, and energy-absorbing effect is limited;Rubber ring obstruction block Standing finish is more, and assembling is inconvenient, and manufacturing cost is high.
The content of the invention
The technical problems to be solved by the invention are to provide one kind can be on the premise of energy-absorbing effect be strengthened, at utmost Reduction material consumption the central guardrail of cellular obstruction block.
The present invention solve the technical scheme that is used of above-mentioned technical problem for:A kind of central guardrail of cellular obstruction block, bag Column, obstruction block and guardrail board are included, described obstruction block side is connected by the first screw assembly with guardrail board, and described deters The opposite side of block is connected by the second screw assembly with column, it is characterised in that described obstruction block is by the polygon of more than three Annular solid is combined.
Further preferred scheme is the present invention:Described obstruction block is combined by four hexagonal rings bodies.
Further preferred scheme is the present invention:Four hexagonal rings bodies constitute a total ring bodies, four hexagons Annular solid is provided centrally with hollow rectangular elastomer.Rectangular Elastic physical efficiency absorbs the kinetic energy that obstruction block is subject to.
Further preferred scheme is the present invention:Four hexagonal rings bodies are respectively the first hexagonal rings body, second Hexagonal rings body, the 3rd hexagonal rings body and the 4th hexagonal rings body, the first hexagonal rings body and the 4th hexagon Annular solid is disposed adjacent and shares the first connection wall, and the second hexagonal ring body is located at the surface of first connection wall, second Hexagonal rings body and the first hexagonal rings body share the second connection wall, the second hexagonal rings body and the 4th hexagonal ring Body shares the 3rd connection wall, and the 3rd hexagonal ring body is located at the underface of the first connection wall, the 3rd hexagonal rings body and the One hexagonal rings body shares the 4th connection wall, and the 3rd hexagonal rings body shares the 5th with the 4th hexagonal rings body and is connected Wall.Structural reliability is better, when receiving external impact, can faster transmit and absorb energy.
Further preferred scheme is the present invention:Described rectangular elastomer has D3O materials to be made.D3O is a kind of expansion Property foamed material, D3O materials keep loose state under normal conditions, soft and flexible, once by hard hit or squeeze When pressure, intermolecular mutually locking at once is tightened up rapidly and is hardened to digest external force, one layer of overcoat formed, when external force disappears After mistake, material can be returned to the soft bullet state of its initial relaxation.It interior in nanometer second can make in different impact conditions Different reactions.
Further preferred scheme is the present invention:The side wall of described rectangular elastomer passes through the 3rd screw assembly and The side wall connection of one hexagonal rings body, the opposite side wall of described rectangular elastomer passes through the 4th screw assembly and the four or six The side wall connection of side shape annular solid.
Compared with prior art, the advantage of the invention is that four cross sections constitute one for the annular solid of hexagonal structure Individual cellular obstruction block, alveolate texture is the structure of full blast, can be on the premise of proof strength, farthest The consumption of material is reduced, manufacturing cost is low;When guardrail board is being hit, the power that guardrail board is subject to is delivered to the one or four first Power is passed to second, third and fourth annular body by side shape annular solid, the first tetracyclic ring body again, and each annular solid produces shape Become and absorb impact, unabsorbed power is finally delivered to power post by fourth annular body so that impact can be greatly reduced, Energy-absorbing effect is good;Multiple hexagonal ring body by integral forming are set, and adjacent ring body shares a connection wall, the letter of this spline structure Single, assembling is easy.
