Description

Impact absorption and space-material of guide-rail}

The present invention relates to a shock absorbing and spacing member of the guide rail, and in detail, to maintain a certain distance with the road, to sequentially absorb the shock and the spacing member of the guide rail that can be used for a long time step by step to reduce the impact.

Guide rails installed on both sides or the center line of the road to protect the vehicle occupants by limiting the width of the road and preventing the vehicle from moving out of the road or crossing the center line are guided by bolts and nuts. The guide rail is assembled with the prop and the front of the guide rail is formed with one goal or two bones and two or three floors.Therefore, there is no separate device and parts to reduce the impact force when colliding with the vehicle. There has been a problem that the damage of the vehicle and the guide rail is increased.

In order to solve this problem, there have been many studies to reduce the impact in the collision by attaching an anti-shock agent between the guide rail and the support when manufacturing the guide rail.

Korean Utility Model Publication No. 99-156874 discloses that a buffer member disposed between an H-beam and a guide rail has an H-shaped steel receiving groove and a plurality of uneven portions formed, and the buffer member, which is placed between the steel pipe and the guide rail, has a circular cross section. It is a rubber product that takes the shape and has the concave-convex projection on the surface of the rear end and the steel pipe receiving groove and the front end.

The rubber material of the present invention is hard to be used for a long time due to the hardening phenomenon due to the deterioration of the rubber's characteristic properties (elasticity), especially when exposed to the natural environment (sun, moisture, atmosphere) for a long time to the atmosphere, the shock absorbing member There is a high risk of breakage, there is a problem in that the discomfort and construction period is long to find a cushioning member to fit the holding posts are different from each other when assembling.

In order to solve the problems of the prior art, the present invention is designed to primarily absorb shocks by collapsing the shock absorbing and spacing members by collision of the vehicle, and secondaryly unfolding the guide rail plates. It is an object of the present invention to provide a shock absorbing and spacing member of a guide rail that has been improved to absorb shock.

Shock-absorbing and spacing member (1), through hole (2), strut (3), guide rail plate (4), bolt (5)

In order to achieve the above object, the present invention has a cylindrical pipe-shaped support (3) having a plurality of through holes (6) formed on one side of the upper part, and is attached to one side of the front and rear upper parts of the support (3), and has a plurality of through holes ( 2) formed shock absorbing and spacing member (1), and installed on the outside of the shock absorbing and spacing member (1), the guide rail plate (4) to give a plurality of bends (3) to absorb shocks when the vehicle and the impact (4) It relates to the shock absorbing and spacing member of the guide rail consisting of).

When the vehicle collides from the front or side of the guide rail, the invention primarily absorbs the shock as the guide rail is pushed toward the prop and the shock absorbing and spacing members are crushed by the strong impact on the guide rail. As the curve of the rail is unfolded, the shock is absorbed and the shock is gradually absorbed and reduced. The structure is identical to the shape of the standard guide rail currently being implemented by the Ministry of Construction and Transportation. It is devised to make.

The present invention can maintain the overall height of the guide rail as the standard height of the Ministry of Construction and Transportation, and when the road floor is raised by reconstruction, the guide rail plate is installed on the prop and keep the standard height at all times. In the event of a collision, other bones are stretched out to absorb the shock, and the shock absorbing member also absorbs the shock and reduces the phenomenon of being thrown out by reflex action. The structure of the guide rail can be arbitrarily controlled by reducing the collision or the collision damage, and by controlling the shock absorption and the number of fastening of the spacer member.

Hereinafter, with reference to the drawings will be described in detail.

1 is a detailed view of the shock absorbing and spacing member of the guide rail of the present invention, Figure 2 is an exploded view of the shock absorbing and spacing member of the guide rail of the present invention, Figure 3 is a shock absorbing and spacing member of the guide rail of the present invention It is shown that the construction state diagram of the shock absorbing and spacing member (1), through hole (2), strut (3), guide rail plate (4), it can be seen that the bolt (5).

Looking at the structure, as shown in Figure 2, a cylindrical pipe-shaped support (3) having a plurality of through holes (6) formed on one side of the upper, and is attached to the front and rear upper sides of the support (3) and installed a plurality of through holes ( 2) formed shock absorbing and spacing member (1), and installed on the outside of the shock absorbing and spacing member (1), the guide rail plate (4) to give a plurality of bends (3) to absorb shocks when the vehicle and the impact (4) It relates to the shock absorbing and spacing member of the guide rail consisting of).

Fig. 1 shows the shock absorbing and spacing member 1 in detail, which is a cylindrical shape in which two pipes are combined, and when viewed in plan view, the inner side is formed to be gently concave overall so as to coincide with the pipe-shaped support 3. Is formed, and consists of a plurality of through-holes (3) formed to be coupled to the bolt (5) on the inner and outer upper one side,

3 is a view illustrating the construction of the shock absorbing and spacing members of the guide rail of the present invention, and in more detail, the shock absorbing and spacing members 1 are formed in the through hole 6 formed on one side of the upper part before and after the support 3. ) And position the guide rail plate 4 on the outside of the shock absorbing and spacing member 1, then assembling with bolts 5, or the shock absorbing and spacing member on the upper side before and after the strut 3. (1) is welded and attached, and then the guide rail plate 4 is welded and attached to the outside of the shock absorbing and spacing member 1 to assemble and install.

The installation of the shock absorbing and spacing member 1 relates to the shock absorbing and spacing member of the guide rail which can be installed so as to arbitrarily adjust the spacing of both guide rails by adjusting the number of additional fastenings as necessary. .

The present invention manufactured as described above, by absorbing the shock absorbing force and the absorption force of the spacer member and the impact of the steel plate is stretched to absorb the shock, when the car crashes out of the guide rail facilities to reduce the risk of accidents At the same time, it is effective in reducing construction cost and construction cost without requiring additional construction and subsidiary materials.
