Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention aims to provide a novel highway protective guard, which is used for improving the buffer capacity of the highway protective guard.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
As shown in fig. 1 to 3, the present embodiment provides a novel highway protective guard, which comprises a column 1, a corrugated steel plate 2, an energy absorption box 3 and a fastener.
The energy absorption box 3 is used as an intermediate structure for connecting the upright posts 1 and the corrugated steel plate 2, and plays a role in buffering and absorbing energy. The energy absorption box 3 is welded and fixed on the side surface of the upright post 1, and one surface of the energy absorption box 3, which is opposite to the upright post 1, is a curved surface which is consistent with the side surface of the upright post 1 in shape. One side of keeping away from stand 1 on the energy-absorbing box 3 distributes along vertical direction has a plurality of first connecting holes 7, and first connecting hole 7 is the round hole, and first connecting hole 7 supplies bolt 4 to pass.
The corrugated steel plate 2 is provided with outward protruding wave crests and inward sunken wave troughs, the wave troughs are flat plates, and the wave troughs are used for being attached to one surface, far away from the upright post 1, of the energy absorption box 3. A plurality of second connecting holes 8 are symmetrically formed in the two ends of the corrugated steel plate 2, and the second connecting holes 8 are linearly distributed along the width direction of the corrugated steel plate 2. Each second connecting hole 8 corresponds to a wave trough, the second connecting holes 8 at the adjacent ends of the two corrugated steel plates 2 are mutually overlapped, and the bolts 4 can penetrate through the overlapped second connecting holes. The first connection holes 7 and the second connection holes 8 are the same in number and correspond in position. The fastener comprises a bolt 4 and a nut 5, and the bolt 4 penetrates through a second connecting hole 8 at the overlapped part of the corrugated steel plate 2 and a first connecting hole 7 on the energy absorption box 3 and then is in threaded connection with the nut 5.
When the energy-absorbing box is used, the upright post 1 is fixed at two sides of a highway, the energy-absorbing box 3 is fixedly welded on the upright post 1, the energy-absorbing box 3 is positioned at one side of the upright post 1 close to the highway, after the adjacent end parts of the two corrugated steel plates 2 are overlapped, the bolt 4 penetrates through the second connecting hole 8 of the overlapped part and the first connecting hole 7 on the energy-absorbing box 3, the nut 5 is screwed on the bolt 4 in the energy-absorbing box 3, and finally the cover plate of the box body is covered. In this embodiment, the box body is formed for the welding of polylith steel sheet, and the apron is welded at last.
When an automobile runs at a high speed and collides against a guard rail, there are two cases. If the automobile collides against the upright post 1, the energy absorption box 3 and the corrugated steel plate 2 play a role in buffering double deformation energy absorption. If the automobile collides against the corrugated steel plate 2 between the two upright posts 1, on one hand, the corrugated steel plate 2 is compressed and flattened and absorbs energy, and on the other hand, two energy absorption processes exist in the stretching deformation process of the corrugated steel plate 2. In the first process, the corrugated steel plate 2 is firstly stretched by the bolts 4 in the circular second connecting holes 8, after the bolts 4 in the oval second connecting holes 8 are stretched to a certain degree, the bolts are contacted with the edges of the oval holes, and the corrugated steel plate 2 is stretched for the second time. The length of the oblong second connecting hole 8 should be determined according to the tensile properties of the steel plate, and the bolt 4 in the oblong second connecting hole 8 should be in the middle position.
In order to further improve the cushioning effect, the present embodiment further includes an elastic filler filled in the crash box 3. The elastic filler in this embodiment is a plurality of elastic spheres 6, and those skilled in the art can select other elastic fillers such as elastic blocks. Compared with an elastic block, the direction of the interaction force of the elastic ball body 6 is the connecting line direction of the ball centers, so that the elastic ball body 6 can be impacted and can transmit impact force to a plurality of directions after being impacted. When the elastic ball 6 is squeezed, on one hand, the elastic ball is compressed to absorb energy, on the other hand, the elastic ball moves up, down, left and right (similar to a sandbag) by taking an impact point as a center, and a part of force which originally collides with the upright post 1 in the front-back direction is converted into pressure on the inner wall of the energy absorption box 3 and is rubbed to absorb energy. When the energy absorption box 3 bears impact, the energy absorption box is firstly compressed and absorbs energy, and then is tensioned and absorbs energy by the outward extrusion force of the elastic block. The elastic ball 6 should not be overfilled, and the filling height of the elastic ball 6 is preferably 60% to 80% of the height of the space in the energy-absorbing box 3.
The elastic ball 6 is made of various materials, and those skilled in the art can select the material according to actual needs, and the elastic ball 6 in this embodiment is made of rubber. The rubber elastic ball is a common structure and can be directly purchased in the market, and the details are not repeated.
Specifically, the second connecting holes 8 at the two ends of the corrugated steel plate 2 in this embodiment are three, and include a round hole located in the middle and two oblong holes located on the upper side and the lower side, respectively, and the length direction of the oblong holes is parallel to the length direction of the corrugated steel plate 2.
In order to prevent the upright 1 from falling down, the present embodiment further includes a support rib 9, and the support rib 9 is fixed to the bottom side of the upright 1. The support rib plate 9 is a triangular plate and is welded with the upright post 1. Three supporting rib plates 9 are provided, two of which are respectively distributed on the front side and the rear side of the upright post 1 along the road direction, and the other one is positioned on one side of the upright post 1 far away from the road.
The principle and the implementation mode of the present invention are explained by applying specific examples in the present specification, and the above descriptions of the examples are only used to help understanding the method and the core idea of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.
