Description
Technical field
The utility model relates to the anti-collision facility of highway and bridge, particularly relates to a kind of reinforced ring ripple joist steel guardrail.
Background technology
Along with the fast development of highway in China construction and communication, traffic safety is faced with severe situation, and anticollision barrier, as a kind of safety device, plays important protective action to the traffic safety of highway and bridge.And current traffic safety facilities field, the utilization rate of traditional double corrugated beam barrier occupies the market share of more than 95%, this guardrail form oneself state uses till today when starting to build speedway always, along with the progressively development of China's road design and its construction level, the limitation of traditional corrugated beam barrier is more outstanding:
1, the unicity of guardrail height.Vehicle in China's road driving, from large, medium and small type and passenger vehicle and lorry, vehicle and technical data more and more abundanter, and traditional double wave beam guardrail just simply adopts the guardrail board of one piece of fixed dimension as crossbeam, and guardrail board width and be highly all fixing, from height of interception, the large car height of interception requirement different with compact car cannot be taken into account at all.
2, the unicity of guardrail rigidity.Tradition double wave beam guardrail only realizes the object of both anti-large cars anti-compact car again by one piece of guardrail board, and the collision energy that large and small type vehicle has an accident when colliding guardrail is widely different, all first guardrail board guarantees to tackle large car on thickness is arranged, and compact car has an accident collision guardrail, traditional corrugated beam barrier lacks flexibility in protection vehicle needed for driver and crew's safety and pooling feature.
3, the cost of guardrail.Traditional double wave beam guardrail is in order to increase the impact resistance of crossbeam, crossbeam lower edges all can be set to aduncate multi-layer annular structure, and add cable wire in loop configuration inside, this design adds the consumptive material of crossbeam undoubtedly, increase cost, in addition cable wire add the consumption also further increasing cost.
4, column damping, buffering effect are poor.The column of existing ring ripple joist steel guardrail all adopts cylindrical hollow body, and top cover is added a cover on column top, and this column cannot play the effect of good damping, buffering when there is traffic accident, is ring ripple joist steel guardrail significant components to be improved.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of structure is simple, good buffer effect, safe and reliable reinforced ring ripple joist steel guardrail.
The utility model reinforced ring ripple joist steel guardrail, wherein, comprise the first column, second column, upper strata crossbeam, lower floor's crossbeam, obstruction block and reinforcement backboard, the tubular structure of the first column and the second column to be all cross section be " C " shape, the centre position of adjacent two first columns is equipped with the second column, first column is fixedly connected with obstruction block rear end respectively with the outer wall of the second column, the upper and lower of obstruction block front end has been arranged side by side upper strata crossbeam and lower floor's crossbeam respectively in the horizontal direction, upper strata crossbeam and lower floor crossbeam are respectively polylith guardrail board head and the tail and are connected successively, overlapping covering place of head and the tail of adjacent two pieces of guardrail board is fixedly connected with the obstruction block on the first column respectively, each guardrail board centre position is fixedly connected with the obstruction block on the second column, the contact position of obstruction block front end and upper strata crossbeam and lower floor's crossbeam is bonded to each other, obstruction block and be also equipped with reinforcement backboard between upper strata crossbeam and lower floor's crossbeam.
The utility model reinforced ring ripple joist steel guardrail, wherein said guardrail board comprises again body and is positioned at the edge part of body both sides, body is arc, and both sides of the edge portion is connected with the top of body and bottom respectively, and is bent to form loop configuration to the opposite direction of body.
The utility model reinforced ring ripple joist steel guardrail, the arc-shaped recess place of the body of wherein said obstruction block front end and upper strata crossbeam and lower floor's crossbeam is bonded to each other.
The utility model reinforced ring ripple joist steel guardrail, wherein said obstruction block is loop configuration, obstruction block is vertically arranged on the outer wall of the first column and the second column, and the end of tightening of the first bolt makes the rear end of obstruction block be separately fixed at the first column and the second column through the side sidewall of the first column and the second column and opposite side sidewall respectively successively.
The utility model reinforced ring ripple joist steel guardrail, the shape of wherein said reinforcement backboard is identical with the shape of obstruction block front end.
The utility model reinforced ring ripple joist steel guardrail, the material of wherein said first column, the second column, upper strata crossbeam, lower floor's crossbeam, obstruction block and reinforcement backboard is all Q235 steel.
The utility model reinforced ring ripple joist steel guardrail difference from prior art is: the first column and the second column are all designed to the tubular structure that cross section is " C " shape by the utility model, further buffering and damping effect can be played when there is traffic accident, casualties and property loss that accident causes can be reduced.Be provided with double-deck guard bar structure, the horizontal depth of beam of upper strata crossbeam and lower floor is respectively the collision height of large car and compact car, increase the stressed width of guardrail entirety, improve the barrier propterty to large car and compact car simultaneously, be particularly suitable for using above city expressway in the majority with dolly in driving vehicle and speedway.The body both sides of guardrail board are bent to form the edge part of loop configuration respectively to self opposite direction, when vehicle and guardrail board collide, edge part carries out the action of opening, curling, flattening deformation these three absorbs vehicle energy successively, thus extend collision time, to the buffer time that vehicle is enough, be vehicle release kinetic energy.Between adjacent two first columns, be equipped with the second column, better reinforcement effect is played to upper strata crossbeam and lower floor's crossbeam, ensure that the impact resistance of reinforced ring ripple joist steel guardrail.
Be described further below in conjunction with the novel reinforced ring ripple joist steel guardrail of accompanying drawing to this practicality.
