Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a structure for reinforcing a guard rail for a dike,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guardrail stiffening structure for a dike, and more particularly to a stiffening structure of a stiffener for a guardrail or a fence for protecting a vehicle installed on a road equipped with a dike.

The guard rail or fence for protecting the vehicle prevents the vehicle out of the normal traveling route from being separated from the road, the opposite lane, the sidewalk, etc., while at the same time minimizing damage to the occupant and damage to the vehicle, It is a facility.

However, since the vehicle frequently collides with the protective guard rail or the fence and leaves the road, it is necessary to reinforce the safety of the roadside fence to reduce the traffic accident such as overturning or falling of the vehicle. Particularly, since the horizontal support force of the vehicle-guarded fence installed in the embankment is lower than 70% of that of the flat section, even in the case of the guard fence that has passed the crash test of the flat part, it is difficult to secure the safety in the embankment, There is a need for a reinforcement plan.

On the other hand, in order to reinforce the horizontal support force in a vehicle protection fence installed on a road provided with a sidewall along an edge boundary for road surface drainage, a method of integrally forming with a sidewall of a vehicle protection fence has been proposed.

Specifically, in the conventional technique, after the main strut of the vehicle protection fence is driven in the ground, the reinforcing bars are arranged adjacently to the outside of the main strut, and then the main strut and the reinforcing bars are integrally cast , And the main strut, which is horizontally moved by the impact force due to the vehicle collision, is reinforced by the tensile force of the reinforcing bars in the concrete. The reinforcement structure and method of reinforced concrete reinforced concrete integrated type can increase the horizontal support force of the main support of the vehicle protection fence without additional reinforcing pavement when the slope of the slope of the site is considerably urgent or the compaction of the ground is very weak .

However, in the case of such a structure and method for reinforcing a single-unit type vehicle-guard fence, the construction is inconvenient because it involves concrete piling after piling, and partial repair is difficult in case of a car accident. There is a problem that the maintenance work is delayed and the cost is increased because the dismantling and dismantling work of the existing sphere and the rebar must be preceded. Also, in relation to the horizontal displacement behavior of the main stiffener, the initial horizontal displacement is maintained in a state of extremely suppressed by the hard concrete, and after the sudden horizontal displacement with the failure of the concrete, , It is disadvantageous in securing the safety of the vehicle and the passenger while preventing the damage of the main support by ensuring a gentle buffering effect in the event of a vehicle collision.

As shown in Figs. 21 and 22, the second connecting means 300b is a zigzag type horizontal plate type reshaping with a regular repeatability in the left and right direction, and is provided with a pair of symmetrical structures on the dies 20, The other end is fixed to the entire surface of the first connecting portion 220 of the second reinforcing member 200 by welding or the like while the other end is fixed to the second reinforcing member 20 by the anchor bolt, A pulling force is generated in the second connecting means 300b by the external pressure of the pillar 10 and the second reinforcing member 200 at the time of the vehicle collision at the pillar 10 and the curved portion of the second connecting means 300b is spread An opposing stress is generated and at the same time an external pressure relieving action is generated, so that the supporting force of the support 10 is strengthened.

22 (a), 22 (b) and 22 (c), a plurality of buffer holes 301 are formed so as to be spaced apart from each other in the longitudinal direction of the second connecting means 300b, A cushioning hole 301 formed to be spaced apart in the longitudinal direction of the connecting means 300b and a connecting hole 302 formed to be connected to the cushioning hole 301 are formed or a connecting means 300b, And a damper 303 is formed in the longitudinal direction of the guide rail 303. The guide rail support reinforcement structure for a dike is provided.

The upper portion of the dike 20 is positioned at an intermediate position where a plurality of buffer holes 301 or buffering cut holes 303 are arranged in the second connection means 300b and the anchor bolts are fixed to the dies 20 When the second connecting means 300b moves in the direction in which the column 10 is positioned by an external pressure generated in the event of a vehicle collision, the buffer hole 301 or the buffer hole 303 is pressed against the anchor bolt on the basis of the anchor bolt Or the second connection means 300b which is to be moved in close contact with the outer surface of the support 10 gradually exerts a stopping force to relieve and absorb the energy of the external pressure,

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Will be clear to those who have knowledge of.
