Abstract

The buried reinforcing structure of the guard rail for the guard rail of the present invention is a guard rail for the guard rail which is installed standing on the ground while supporting the beam of the ground. It consists of inserting and fixing.

This structure supports the back of the support post by the ground when the vehicle collides, since the reinforcement is embedded with the support post after inserting and fixing the reinforcement in the through hole of the support post. It is possible to easily reduce the collision of the vehicle to the rear of the guardrail, and since the reinforcement inserted into the through hole of the support is formed in a flat shape, no bending work is required, so the thickness of the thick reinforcement can be easily used. The reinforcement can be easily manufactured in accordance with the holding post, thereby reducing the unit cost of the product due to improved workability.

Description

Buried reinforcement structure of guard rail for guardrail {STRUCTURE OF SUPPORTER FOR GUARDRAIL}

The present invention relates to a buried reinforcement structure of a guardrail support, and in particular, it is possible to easily prevent the props buried in the ground from falling easily in a vehicle crash and to improve workability and easily reduce the unit cost of the product. The buried reinforcement structure for guard rail props.

In general, guardrails are installed on roadsides, sidewalks and driveway boundaries, in the middle of highways to protect pedestrians by preventing cars from falling out of lanes, falling down hills, or rushing vehicles to sidewalks.

And the guardrail is to install a beam between a plurality of struts to be installed on the ground, the surface of the beam is painted in bright colors to be visible to the driver.

The guardrails thus formed absorb the collision of the vehicle and prevent the vehicle from overturning behind the guardrail of the vehicle, leading to the vehicle's original course.

However, since the lower end of the guard rail is conventionally installed on the ground as it is, when the vehicle collides, the vehicle does not pierce through the beam of the guard rail, but instead the vehicle is continuously rushed out as the guard rail of the guard rail falls backward. The disadvantage is that it can cause an accident.

Therefore, in order to supplement the above disadvantages of the prior art, there is a buried reinforcement structure of the guard rail support pillar registered by the applicant No. 20-365454, which is shown in FIG. Fixing the reinforcement (102) in the transverse direction at any one of the front and rear of the lower end portion, fastening the reinforcement (102) to the support base 101 with bolts (102a) and nuts (102b) or welded It is structured.

Here, conventionally, the center portion of the reinforcing tool 102 is bent to coincide with the half surface of the support stand 101, and the center portion of the reinforcing tool 102 is brought into close contact with the support stand 101, and the support stand is welded. Fixing the reinforcement 102 to the 101 or using a bolt and nut to fix it to the holding base (101).

However, in the prior art, the center portion of the reinforcement is bent to match the half surface of the support, so the bending work of the reinforcement is difficult and the workability is very low, and the reinforcement is not precisely processed since the reinforcement is fixed to the surface of the support. Without it, the reinforcement can not be firmly fixed to the props, there is a disadvantage that the overall workability is very poor.

The present invention is designed to solve the conventional problems as described above, the present invention is easy to prevent the props buried in the ground easily fall in the event of a vehicle collision and improve the workability to easily reduce the unit cost of the product The purpose is to provide a buried reinforcement structure for guardrail props.

Therefore, the present invention, in order to achieve the above object, in the support for the guardrail to be installed standing on the ground while supporting the beam of the ground, forming a through-hole in the lower end of the support, and reinforces the through hole of the support It provides a buried reinforcement structure for guardrail props consisting of inserting and fixing a sphere.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, a preferred embodiment of a buried reinforcing structure for guardrail support according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing an example of the guardrail to which the buried reinforcement structure according to the present invention is applied, wherein the guardrail 1 is a beam in the longitudinal direction between a plurality of struts 11 erected on the ground (2) It consists of a structure in which (12) is installed.

In the present embodiment, the shock absorbing opening 13 is installed between the support base 11 and the beam 12 to reduce the impact force of the vehicle as the shock absorbing opening 13 is deformed when the vehicle collides.

The present invention is to prevent the fall of the support base 11 by fixing the reinforcement (10) to the lower portion of the support base (11) embedded in the ground (2).

That is, the buried reinforcing structure of the guard rail support post of the present invention, as shown in Fig. 2 and 3, the through hole (11a) is formed at the lower end of the support post 11 in the vertical direction, the support post 11 The reinforcing hole 10 is inserted into and fixed to the through hole 11a of).

In this case, in order to fix the reinforcement 10, the support base 11 and the reinforcement 10 may be welded as shown in FIG. 2, and the support base 11 and the reinforcement as shown in FIG. It is also possible to fix the (10) with the bolt nut (14).

On the other hand, it is preferable to position the support stand 11 in the central portion of the reinforcement 10, it is preferable to improve the workability, as shown in Figure 4 in the center of the upper and lower sides of the reinforcement 10, the locking projection (10a) Is formed to be caught outside of the through hole (11a) of the support base (11).

Then, the worker inserts the reinforcement tool 10 into the through hole 11a of the support stand 11 and pushes it until the catching protrusion 10a is engaged, and the reinforcement tool 10 and the support stand 11 are simply It will be fixed.

The buried reinforcement structure of the guardrail for the guardrail according to the present invention made as described above acts as follows.

First, the reinforcement 10 is fixed to the lower end of the support base 11, and then the lower end of the support base 11 is embedded in the ground 2 together with the reinforcement 10, and the support base 11 protrudes to the ground. In FIG. 1, the shock absorber 13 and the beam 12 are installed.

In this state, even when the vehicle strikes the beam 12 and the props 11 fall, the reinforcement 10 embedded in the ground 2 acts as a reaction force by the ground 2, so the reinforcement 10 ) Is fixed to the support stand 11 is not easy to fall.

Thus buried reinforcement structure of the present invention makes it easy to maintain the buried state of the support base 11 is installed as it is on the ground (2).

As described above, the buried reinforcement structure of the guardrail support post according to the present invention embeds the reinforcement with the support post after fixing the reinforcement to the through-hole of the support post, so when the vehicle collides, the support post is supported by the ground. By supporting the rear side, the props can be easily prevented from falling easily, and the crashed vehicle can be easily reduced from rushing behind the guardrail.

In addition, since the present invention forms a flat shape of the reinforcement inserted into the through hole of the support, there is no need for bending work so that the thickness of the thick reinforcement can be easily used, and the reinforcement can be easily manufactured in accordance with various props. There is a further advantage that the cost of the product can be reduced due to the improved workability.
