Description

The Impact Absorbing Panel for the Concret Median Barrier and the Protective Walls}

The present invention relates to a shock absorbing panel, and more particularly, to the attachment of the shock absorbing panel to one side of the concrete structure of the central partition of the road and the firewall.

In general, the central separator used in the prior art is a self-healing central separator (SERB), a sand-filled central separator, a concrete-type central separator, earthquake central separator and the like. And the most used of these is the concrete type median. In any case, the wider the median, the better its function, but it is problematic to make the median wider only in consideration of road site acquisition and land use. Therefore, it is basic to install the separator with a smaller width and higher than the roadway drawing.

In addition, the most widely used is the concrete concrete type centrifuge, which is considered to be the most intact for safety and economic feasibility, but in case of a vehicle crash, rollover or interlacing occurs frequently. And because the material is too rigid, the damage of the crash vehicle is not only great, but the driver loses consciousness in the first collision, which makes the vehicle impossible to control, causing a second accident that collides with the vehicle driving behind. Often followed. For this reason, in the past, the New Jersey type with the slope change point height of 325 mm has been used in the concrete median divider. However, through the steady development and experiment, the change in the height of the slope change point is changed to the F type with 250 mm height, which reduces the vehicle's rollover accident. The problem is not solved.

The biggest problem among these problems is that these median separators are designed based on passenger cars. For this reason, when a heavy vehicle is shocked, a sufficient margin protection device is required, but the margin protection device is not sufficiently considered as a conventional median separator. However, if the central separator is installed mainly on heavy vehicles, a great economic burden is required.

In addition, no protection device or related technology has been introduced to the rigid concrete firewall on the slope of the roadside due to the vehicle crash.

The present invention is to solve this problem, and the most economical and the most economical way to the impact of the shock absorbing structure by changing the material of the concrete partition from rigidity to elastic material The solution is to solve the problem. In addition, the present invention facilitates maintenance, attaches a reflector, improves visibility, promotes safe driving, freely selects colors, improves aesthetics, and provides eco-friendly products using recycled materials. It is a technical task of the present invention to have a secondary function that is. The technical problem of the present invention is that the present technology can be attached to concrete barriers on mountain slopes so as to ensure safety during a collision of the vehicle.

The vehicle protective shock absorbing plate according to the present invention for achieving the above object is characterized in that the buffer plate is fixed to the concrete surface of the center separator and the protective wall is provided with a shock-absorbing plate when colliding with the vehicle.

The buffer plate protrudes forward and has a plurality of curved portions having a curved shape; A concave portion having the curved portion connected to the flat portion; Characterized in that it consists of a buffer portion protruding in a concave-convex shape in front of the bent portion is provided with a buffer space portion for reducing the impact therein.

The shock absorbing material is embedded in the buffer space portion, and the reflector is preferably attached to the front surface and the concave portion of the buffer portion.

Hereinafter, an embodiment of a vehicle protective shock absorber according to the present invention will be described in detail with reference to the accompanying drawings.

In this case, the same reference numerals are given to components that perform the same function in FIGS. 1 and 2, and illustrations of components for connection, coupling, and fixing of main elements in each drawing are briefly or omitted. The illustration of the components that can be applied basically to the practitioners in the field is omitted, and shown mainly on the parts related to the present invention. In particular, although the ratio of the size between the components is expressed somewhat differently or the size between the parts that are combined with each other is expressed, the representation difference of such drawings can be easily understood by those skilled in the art Parts are omitted here.

1 is a perspective view of a vehicle protective shock absorber according to a preferred embodiment of the present invention, Figure 2 is a cross-sectional view taken along the line A-A of FIG. 1 to 2, the vehicle protective shock absorbing plate according to the present invention is provided with a shock absorbing plate 30 that is tightly coupled to the concrete front portion of the barrier wall of the center separator and the slope to absorb the impact when colliding with the vehicle, which It is preferably formed of thermoplastic synthetic resin (including recycled plastics and rubbers). The buffer plate 30 protrudes forward to have a plurality of curved portions 32 having a curved shape and the curved portions 32 are connected to a concave-convex portion 34 having a flat surface and an uneven shape in front of the curved portion 32. It is composed of a buffer unit 32 is repeatedly formed by protruding to absorb and attenuate the impact amount of the vehicle.

As shown in FIG. 2, the shock absorbing portion 33 is protruded forward of the curved portion 32 such that the shock absorbing space portion 35 continuously absorbs the impact energy generated when the vehicle collides with the vehicle. It is formed a plurality of, the shock absorbing material 36 is charged in the buffer space (35).

In the present embodiment, the buffer space 35 is shown as a closed type, but will not be limited to that form. For example, an injection process or secondary processing (air) may be used, or a shock absorber such as sand or water may be filled to improve the buffering effect.

In addition, the buffer portion 33 is formed to protrude toward the front surface at regular intervals along the bent portion (32). Such a configuration of the shock absorbing portion 33 not only makes it possible to form a shock absorbing space therein, but also can be easily transported while reducing the volume by staggering the uneven shape of the shock absorbing portion 33 when overlapping or rolling. To be created. On the other hand, in the buffer part 33 of the present embodiment, the uneven shape is to have a rectangular shape, but other uneven shapes may be formed.

A delineator 37 is attached to the front face and the concave part 34 of the shock absorbing part 33 to support safe driving of the vehicle driver at night and in the middle of the rain.

3 shows that the shock absorbing member 36 is omitted because the buffer space 35 is filled with air.
