Description

Guardrail {GUARD RAIL}

The present invention relates to a guard rail to reduce the impact of the vehicle accident is installed on the edge of the road or bridge, and more specifically, when the vehicle is separated from the road due to the accident, the guard rail is installed in multiple stages of the departure and fall of the vehicle The present invention relates to a guardrail which can prevent the damage and obtain the effect of deformation and impact reduction of the vehicle.

In general, the guard rail is installed at the edge of the road in order to prevent the vehicle from falling off the driving lane of the road or falling from the bridge or the cliff, while steel guard rails and concrete barriers are mainly used.

The steel guard rail is constructed by burying pillars made of round, H-shaped or quadrangle, and fixing the guard rails having a corrugated shape by bolting the upper and lower portions of the pillars in two layers. The strut is installed to absorb the impact force, but if excessive impact is applied, the upper side of the strut is deformed larger than the lower side, which may cause an accident that the vehicle falls over or falls off the guard rail.

In addition, the concrete firewall is installed on the center line or the edge of the road to prevent the accident vehicle from invading into the opposite driving lane or falling from the bridge or cliff, rather than reducing the damage of the occupant of the accident vehicle or the vehicle itself in the event of a collision. Is installed. When the vehicle collides with the concrete barrier, the concrete barrier does not absorb the impact force caused by the collision of the vehicle, and a large portion of the impact force is transmitted to the vehicle and the occupant, thereby greatly causing damage and injury to the vehicle. Thus, there is a need for means to protect vehicles and occupants from concrete barriers.

In the conventional steel guard rail or concrete barrier, the vehicle is largely deformed when the vehicle collides, and thus a large damage is generated. Therefore, a special device is required to absorb or disperse the impact to reduce the deformation of the vehicle.

The present invention is to install a multi-stage guard rail at regular intervals to the road or the bridge to minimize the deformation of the vehicle and to absorb or disperse the impact caused by the collision when the vehicle collides with the guard rail off the driving road The purpose is to provide a guard rail using a spring and wire that can prevent the vehicle from falling or falling over the guard rail.

In order to achieve the above object, the present invention embeds a plurality of supporting members made of a pillar having a circular to square section at the bottom and a steel pipe column tapered at the top at regular intervals, such as the edge of the road or bridge, In the guard rail provided to connect the two springs or wires to minimize the impact on the vehicle in the event of an accident of the vehicle, the spring has a ring portion at both ends to be inserted into the steel pipe pillar, buried in the first row A plurality of first springs are inserted into the steel pipe pillars of the supporting members at a predetermined interval upward and fixed, and a plurality of second springs are fixed at a predetermined interval in the steel pipe pillars of the supporting members embedded in the second row. 3 step guard rail by winding the wire around the steel pipe column of the supporting member embedded in the third row. It relates to a guardrail, characterized in that to form.

Here, the support members are buried so as to have a distance (L) of 2m in the lateral direction, and a distance (D) of 0.5 to 0.6m in the front and rear directions, respectively, and the first spring has a diameter of 5 to 30mm and the second spring. Silver guard rails of three stages were formed using each spring formed with a diameter of 5.5-40 mm.

Referring to the configuration of the present invention in more detail with reference to the accompanying drawings as follows.

1 is a perspective view showing a state in which the guard rail 1 according to the present invention is installed, the driving direction and the cross direction of the road (hereinafter, 'the running direction of the road' cross direction ', the road transverse to the edge of the road The guard rails 1 in three stages are installed to extend in the lateral direction at regular intervals in the direction in which they are cut.

In order to install the guard rail 1 according to the present invention, the concrete at one end of the support member 2 made of a concrete support 21 having a circular to square section at the lower end and a steel pipe pillar 22 tapered at the upper end. The support 21 is buried to be perpendicular to the ground, and the support member 2 is embedded to maintain a distance L of 2 m in the lateral direction and a distance D of 0.5 to 0.6 m in the longitudinal direction, respectively. The guard rails 1 are formed by connecting the springs 41 and 42 to the wires 43 to the steel pipe pillars 22 of the buried support member 2, and the tapered steel pipe pillars 22 embedded in the first row. ), The guard rail 1 is assembled by inserting the first spring 41 with a diameter of 5 to 30 mm. The spring may be inserted into three layers or multiple layers upward to form a guard rail, and the spring is inserted into the steel pipe pillar 22 and fixed by filling the fixing band 3 at the upper and lower parts to prevent the spring from being separated. Let it be. In order to assemble the guard rails 1 of the first row, the first springs 41 are continuously connected in the transverse direction. Also, the second spring 42 having a diameter of 5.5 to 40 mm is inserted into the steel pipe column 22 embedded in the second row having the same spacing as the steel pipe pillar 22 embedded in the first row. ) Was assembled and fixed by fixing the upper and lower fixing bands 3 in the same manner as when the first spring 41 was fixed, and the second spring 42 was also inserted upwards in three layers or multiple layers and provided with a guard rail (1). ) And continuously connect the second spring 42 in the transverse direction. On the outermost part of the road, that is, the steel pipe pillars 22 embedded in the third row, the wires 43, which are widely used in the past, were wound two to five times and connected continuously in the transverse direction. In the same manner, the fixing band 3 is fixed by filling the upper and lower portions, and the guard rail 1 is formed in three to several layers upward in the same manner as the assembly of the guard rail 1 by the spring.

When the vehicle collides with the guard rail 1 according to the present invention, the impact and speed are primarily reduced by the first spring 41 installed in the first row of the vehicle, and the first spring 41 is When the vehicle's inertia or impact force cannot be tolerated, the impact and speed are reduced by the second spring 42 installed in the second row, and the vehicle is driven by the first spring 41 and the second spring 42. If this is not prevented, the vehicle is stopped by the wire 43 provided in the third row so that the vehicle does not leave the guard rail 1. To do this, the diameter of the second spring 42 was made larger than that of the first spring 41 so as to take a greater impact. In the case of the conventional guardrail using wire, it is simply placed on a ring provided in the steel pipe column 22. Since it was supported by the jersey, when the wire was extended in the transverse direction when the impact was applied, the wire 43 could not serve as a defence, but the wire 43 connection according to the present invention was wound 2 to 5 times on the steel pipe column 22 to make a connection. As a result, it is possible to exhibit sufficient stopping performance against impact.

It was formed as a circular steel pipe column 22 having a length of 1 m and a maximum diameter of 24 mm tapered at an angle of. FIG. 2B is a first spring 41 inserted into the steel pipe pillar 22 embedded in the first row, and has a length of 2 m and a diameter of 5 to 30 mm, and is fitted into the steel pipe pillar 22. The part 44 is formed in both ends. FIG. 2C is a second spring 42 inserted into the steel pipe pillar 22 embedded in the second row, and has a length of 2 m and a diameter of 5.5 to 40 mm, which may also be inserted into the steel pipe pillar 22. Ring portions 44 are formed at both ends. 2D is a wire 43 wound two to five times on a steel pipe pillar 22 embedded in a third row. The wire 43 is a wire 43 that has been widely used and has a good tensile strength. It is used as a means for stopping a vehicle that has not been blocked by the springs 41 and 42 of the row and the second row.

Figure 3 shows another embodiment of the guard rail 1 according to the present invention, in the installation of the spring guard rail in the steel pipe pillars embedded in the first row and the second row, in three layers to multiple layers in parallel In order to interconnect the first spring 41 or the second spring 42 connected to each other in the vertical direction, the first spring 41 or the second spring 42 is bound to a grid shape by a reinforcing line 6 so as to effectively disperse the impact when the vehicle collides. The guard rail 1 according to another embodiment may also be applied to a case in which it is necessary to form a more compact gap between the grids in some cases to disperse even more impact.

As described above, the present invention absorbs or disperses shocks sequentially when a vehicle collides with a three-step guard rail installed at an edge of a road or a bridge, and at the same time, prevents the vehicle from falling out or falling down the guard rail. In addition, by minimizing the deformation of the vehicle can greatly reduce the damage to life, in particular, it is more effective to install the guard rail according to the present invention in the vicinity of the sharp curve or the cliff.
