Abstract
The utility model discloses a special aluminum alloy wave-shaped protection guard which comprises a guide plate, a pillar and a prevention stop block. The guide plate and the pillar are fixedly connected through the prevention stop block. The guide plate is in a wave shape in the horizontal direction and the lengthwise direction. A certain angle can be formed between the guide plate and a vehicle by means of waves, thus the stress of the guide plate is reduced. The buffering effect of the guard is enhanced and the probability of changing the driving direction of the vehicle is reduced.
Description
Technical field
The utility model belongs to the building field of road, railway or bridge, relates to a kind of special-shaped aluminium alloys waveform protective guard.
Background technology
Guardrail is that livestock stable breeding, Large Residential District, speedway, bridge, large scale industry base and large-scale public place of entertainment on being often used in agriculture is as the anticollision facility of race course, cycling track etc.; Wherein, of paramount importance security protection is traffic, and particularly speedway, through street and bridge, all needs protective guard, and the Main Function of protective guard is to driving vehicle protection, prevents that when accident from appearring in vehicle, going out road causes larger personnel and vehicle loss.
Waveform protective guard of the prior art is generally double wave protective guard and three ripple protective guards, be unidirectional waveform, only there is waveform at horizontal direction (perpendicular to road surface direction), it utilizes the distortion of soil matrix, column, crossbeam to absorb collision energy, and force errant vehicle to change direction, be returned to normal travel direction, prevent that vehicle is run-off-road.But on the higher speedway of the speed of a motor vehicle or urgent bend, because the speed of a motor vehicle is very fast, bump against on guardrail take charge very easily occurs, cause vehicle generation secondary collision, thereby increase the weight of casualty effect; When impact force is larger, adopt the protective guard that galvanized steel plain sheet processes to produce fracture because bearing too large impact force, cause vehicle run-off-road.
Summary of the invention
In view of this, the purpose of this utility model is to provide one can absorb more impact forces, and buffering effect is better, in the time that automobile bumps, can effectively hinder automobile changes the Novel protective handrail of travel direction.
For achieving the above object, the utility model provides following technical scheme: comprise protected apron, column and the obstruction block that both are fixed together, it is characterized in that: the horizontal and vertical waveform that is of described protected apron.
Further, described protected apron adopts double-layer aluminium alloy section bar to make.
The beneficial effects of the utility model are:
(1) longitudinal cross-section of protected apron adopts wave structure, in the time of vehicle and protective guard generation shock, longitudinally wave can make shape between protected apron and vehicle have a certain degree, therefore reduced the stressing conditions of protected apron, strengthen the buffering effect of protective guard, reduced the probability of automobile change travel direction.
(2) protected apron adopts aluminum alloy extrusion section bar, and corrosion resistance is better, and recovery utilization rate is high, has larger impact absorbing energy and impact toughness, can absorb more collision energy, prevents from continuing to move ahead run-off-road because car hit splits protective guard; Reduce the damage that impact force causes automobile simultaneously, guaranteed occupant's safety.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, the utility model provides following accompanying drawing to describe:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional schematic diagram of aluminium alloy extrusions.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, the special-shaped aluminium alloys waveform protective guard of the present embodiment, comprise protected apron 1, column 2 and the obstruction block 3 that both are fixed together, wherein, protected apron 1 is for being laterally longitudinally the integral structure of waveform: the structure of protected apron 1 horizontal (perpendicular to road surface direction) direction is still common wavy surface or double-deck wavy surface, but the structure of longitudinal direction (along road surfacing direction) has also adopted wavy surface; In the time that automobile and protected apron 1 bump, impact makes protected apron 1 longitudinal direction produce certain angular distortion, awave structure has strengthened the angular distortion of protected apron 1, and larger deformation angle will reduce the pulling force of rum point two side protective plates 1, thereby increases crashproof ability; Meanwhile, due to the special construction shape of wave, can continuously change the force direction that is subject to of the rear automobile of collision, prevent that it from directly changing travel direction and secondary collision occurs, and guaranteed the driving safety of other vehicles; Longitudinally the actual size of wave is determined according to road conditions situation.
Protected apron 1 in the present embodiment adopts double-layer aluminium alloy extrudate to make, and because aluminum alloy materials has larger impact toughness, compared with the galvanized steel plain sheet that adopts with routine, can absorb more the collision energy of mistake, to reduce the impact of impact force to automobile itself; Meanwhile, this aluminium alloy extrusions is double-decker, between two-layer aluminium alloy plate, connects with muscle, as shown in Figure 2, can strengthen protective capacities, and extrusion modling material structure is out better, has better mechanical performance, has further guaranteed the impact resistance of protected apron.
Finally explanation is, above preferred embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is described in detail by above preferred embodiment, but those skilled in the art are to be understood that, can make various changes to it in the form and details, and not depart from the utility model claims limited range.
Claims (2)
