Abstract
The utility model relates to a laminating composite energy-dissipation anti-collision element which is mainly applied to anti-collision equipment in the traffic safety field such as highways, rail ways and shipping lanes. The laminating composite energy-dissipation anti-collision element comprises a plurality of C-shaped spring steel plates. The middle portions of the plurality of C-shaped spring steel plates are arranged and stacked at equal intervals. The plurality of C-shaped spring steel plates are arranged inside a C-shaped composite rubber layer as a whole. Two ends of each C-shaped spring steel plate and a connecting ring integrated with the C-shaped spring steel plate are arranged and distributed on the longitudinal section in a mutually staggering mode, and are overlaid in a longitudinal mode to form connecting holes. The connecting holes penetrate through the composite rubber layer in a communicating mode. The laminating composite energy-dissipation anti-collision element has the advantages that when the element is impacted by an outer force, a quality strength ratio of structural whole can be improved by means of staggering distribution of the laminating C-shaped spring steel plates, lightweight structure is benefited, structure yield displacement is large, structure counter-force is high, the structural buffering function is improved to the maximum, the guiding function is achieved, structural deformation energy dissipation is increased due to high damp rubber materials, energy absorption effect is good, durability and adaptability of the energy-dissipation anti-collision element are improved, and service life of the element is prolonged.
Description
Technical field
The utility model is the crashproof element of a kind of lamination composite energy dissipation, is mainly used in the anti-collision facility in the traffic safety fields such as highway, railway and navigation channel.
Background technology
The security performance of means of transportation and the person and property safety are closely bound up; the kind of anticollision device, collision-prevention device is numerous at present; its objective is that the vehicle (or boats and ships) that prevents from sailing out of runway (or navigation channel) knocks the protection facility of fastening devices (or bridge pier), is not directly clashed into building.Anticollision device, collision-prevention device consumes Impact energy by the distortion of element for energy dissipation, prolongs collision time, reduces impact, the safety of protection means of transportation.Ship (car) bump of impact grade when particularly being subjected to to(for) bridge pier is high, most anticollision device, collision-prevention device is to depend on this body structure of bridge pier, so the size of device is larger, cost is higher, how to improve the energy dissipating ability of anticollision device, collision-prevention device and durability and be everybody question of common concern.
Common in the prior art is the monomer structure of C shape steel plate, and its anticollision energy eliminating successful utilizes the conquassation of elastoplasticity steel plate and tears energy-absorbing, but in the situation that outside crashproof power improves, the single structure size will certainly strengthen, thereby increases cost; If adopt merely spring structure, anticollision device, collision-prevention device can't consumed energy, and the bounce of spring also can cause secondary injury to the occupant, will be difficult to return to original shape when plastic strain is larger, and unsuitable long-term outdoor use.
Summary of the invention
The purpose of this utility model provides the crashproof element of a kind of lamination composite energy dissipation, and when be used for consuming external impact power and guide effect is provided, the matter that improves structural entity is by force than, the lightweight of implementation structure; And solve and to recover after being out of shape or bounce can cause to the occupant problem of secondary injury, prolong the application life of energy-dissipating and collision-preventing element;
To achieve these goals, the technical solution adopted in the utility model is:
The crashproof element of a kind of lamination composite energy dissipation, comprise C type steel spring plate, it is characterized in that: described C type steel spring plate comprises several, and the middle part of several C type steel spring plates equidistantly stacks layout, and several C type steel spring plates are arranged in the composite rubber layer of C type as a whole; The connecting ring that is structure as a whole with it at every layer of C type steel spring plate two ends mutually staggers on the longitudinal section and arranges, vertical stacked formation connecting hole, and connecting hole connects composite rubber layer.
The thickness of described composite rubber layer recess side is gradually thin setting from the middle to both ends, protrudes the even thickness of the composite rubber layer of side, and the thickness in the middle of the recess side is greater than the thickness of the composite rubber layer that protrudes side.
Compared with prior art, the utlity model has following advantage and effect:
1. when being subject to external force collision, the connecting ring of arranging by the C type steel spring plate dislocation of lamination makes the external force peptizaiton in the C of individual layer type steel spring plate, the matter that can improve structural entity by force than, be beneficial to light in structure and quantize;
2. the employing high-strength spring steel increases the structure yield displacement, improves the structure counter-force, and structure cushioning effect power is provided to greatest extent, and it realizes guide effect;
3. adopt the high-damping rubber material, increase the malformation power consumption, to greatest extent absorbing impact energy;
4. compounded rubber closely wraps up laminated steel plate and all wrap compounded rubber inside and outside connecting hole, can improve the endurance quality of energy-dissipating and collision-preventing element and compliance, prolongation element for energy dissipation application life.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
The crashproof element of a kind of lamination composite energy dissipation comprises C type steel spring plate, and described C type steel spring plate comprises several, and the middle part of several C type steel spring plates equidistantly stacks layout, and several C type steel spring plates are arranged in the composite rubber layer 1 of C type as a whole; The connecting ring that is structure as a whole with it 5 at every layer of C type steel spring plate two ends mutually staggers on the longitudinal section and arranges, vertical stacked formation connecting hole 6, and connecting hole 6 connects composite rubber layer.The thickness of described composite rubber layer 1 recess side is gradually thin setting from the middle to both ends, protrudes the even thickness of the composite rubber layer 1 of side, and the thickness in the middle of the recess side is greater than the thickness of the composite rubber layer 1 that protrudes side.
