Abstract
The utility model discloses a flexible energy dissipation type pier prevents that car hits device, establish the battenboard structure anticollision wall on the pier including the cover, battenboard structure anticollision wall includes packs flexible energy dissipation material layer between the steel deck, each steel deck of multilayer nested's tube -shape, the bottom and the welding of base steel sheet of each steel deck, and the base steel sheet passes through the anchor nail fixing on the bottom of foundation, and the interior lateral surface of battenboard structure anticollision wall is all including the waterproof cloth. The utility model discloses use the battenboard structure, on the basis of proof strength, the quality lightens greatly to anti bending strength is greatly improved. When bumping the accident, convert the rigidity collision to the elastoplasticity collision, consume a large amount of energy, reduce to collide the peak stress, this peak stress is even as small as the pier to be enough to resist. And in the protection pier, also protected automobile and pedestrian. Simple structure, the construction is easy, the engineering less investment. Easy maintenance has fine economic value.
Description
Technical field
The utility model belongs to pier anti-collision field, more specifically relates to a kind of flexible energy dissipation type pier anti-collision device, and the bridge pier being applicable to all kinds of highway bridge alleviates the SPS(sandwichplatesystem of automobile impacting disaster) structure anticollision device of pier.
Background technology
At present, the traffic safety situation of China is troubling, due to the growth of the traffic volume, the contradiction of automobile and bridge is also further outstanding, the accident of automobile impacting bridge pier happens occasionally, and can bring that bridge pier collapses, car crash time serious, brings Loss of Life and property without redemption.Tracing it to its cause is that this process lacks energy dissipation because automobile directly clashes into bridge pier and belongs to rigid impact, therefore destroys greatly.Therefore take Anticollision Measures particularly necessary to bridge, its basic goal is: prevent bridge from exceeding the design bearing capacity of bridge pier because of automobile impact force, and cause structural failure, protect automobile as much as possible simultaneously, loss is reduced to minimum level.
The anti-car of existing bridge hits design; employing adds Bridge Pier size, adds Anti-collision railing, or builds up a solid watering bottom pier stud; although ensured the safety of bridge pier to a certain extent; but it is attractive in appearance and applicability is not strong, and mostly just considers the safety of bridge, and does not protect automobile; once there is car to hit accident; bridge can be avoided damaging, but automobile and driver's potential safety hazard are not eliminated or reduce, and do not meet the requirement of safety and human oriented design.
A kind of New type of S PS structure, injects elasticity energy-dissipating material, forms composite construction by elasticity energy-dissipating material and steel plate endosexine strong bond between two-layered steel plates.It is that steel plate is relatively thin up and down, and centre is elastomer core, and relative thickness is large.The thickness on top layer mainly improves the hot strength of sheet material, surperficial impact resistance, and core under the effect of guaranteed strength, can alleviate quality, improves bending stiffness.The anticollision device, collision-prevention device using steel to make with tradition is compared, and Sandwich Plates has light weight, more shock-resistant.
Utility model content
The purpose of this utility model is the problems referred to above for prior art, provides a kind of flexible energy dissipation type pier anti-collision device, is difficult to ensure the problem of safety of automobile, pedestrian, bridge pier when solving the generation rigid collision of automobile and bridge pier.
To achieve these goals, the utility model is by the following technical solutions:
A kind of flexible energy dissipation type pier anti-collision device, comprise the crashproof wall of the Sandwich structure be set on bridge pier, the crashproof wall of Sandwich structure comprises between the steel plate layer of the tubular of multilayer nest, each steel plate layer and is filled with elasticity energy-dissipating material layer, the bottom of each steel plate layer and pedestal Plate Welding, pedestal steel plate is fixing on the foundation by holdfast, and the interior lateral surface of the crashproof wall of Sandwich structure has included canvas cloth.
The flexible energy-dissipating material layer of arranged outside of the outermost steel plate layer of the steel plate layer of the tubular of multilayer nest as above, the inner side of the steel plate layer of innermost layer is provided with elasticity energy-dissipating material layer.
The outer surface fluorescence coating of canvas cloth as above.
Canvas cloth 4 as above is the one in PVC canvas cloth, nylon cloth, PU cloth.
The utility model compared with prior art, has the following advantages and effect:
1, with Sandwich structure, on the basis of guaranteed strength, quality alleviates greatly, and substantially increases flexural strength.When crashing, converting rigid collision to elastic-plastic impact, consuming a large amount of energy, reduce impact stresses peak value, this peak stress is little is enough to opposing to bridge pier.And while protection bridge pier, also protect automobile and pedestrian.
2, this apparatus structure is simple, and construction is easy, less engineering investment.Easy to maintenance, there is good economic worth.
