Description

Protective fence assembly with wedge fixing function

The present invention relates to a safety fence assembly in which a guard rail is stably fixed through a wedge-shaped anchor bolt for fixing a guard rail post disposed on a boundary stone of a road.

Guard rail refers to the protective measures installed on both sides of the road for the safety of road traffic. Generally, it is a facility installed to prevent secondary damage from accidents caused by falls or intrusion of the center line, and to protect pedestrians and animals. It is simply made into a fence shape on the edge of a road or bridge, but it is also installed to prevent reverse driving due to intrusion of the center line on a highway.

Guard rails are installed to prevent cars from falling out of the road on mountain roads or roads with many curves. . The guard rail must have enough structural rigidity to withstand the collision of a moving vehicle with the rail, and also have the ability to absorb shock for the safety of occupants.

As described above, the role of the guard rail is an important facility that determines the life of a driver. On the other hand, safety and life-saving guardrails sometimes lead to more serious accidents, but there may be guardrails that penetrate the vehicle due to poor or faulty construction or fail to function due to the low height. Even recently, the number of fatalities due to accidents after the collision of guard rails is a serious matter, and the way to prevent such accidents is to install properly standardized products.

The protection fence assembly having a wedge-shaped anchor bolt according to the present invention is characterized in that it is constructed along a boundary stone disposed on a road, and specifically, a plurality of guard rail holding modules 100 disposed at a predetermined interval on the boundary stone; a guard rail 200 arranged in such a way that a plurality of guard rail holding modules 100 are connected; and a shock absorber 300 disposed between the guard rail 200 and the plurality of guard rail post modules 100 .

The guard rail post module 100 is a guard rail post 110 exposed on the upper portion of the boundary stone 2 formed in the ground 1, and a lower post extending and coupled to the lower portion of the guard rail post 110. (120), the inner reinforcement pole 130, the lower strut 120 is coupled to the lower end of the pole fixing anchor bolt 140 and the lower strut connected between the guard rail strut 110 and the lower strut 120. It is formed to protrude outward from the upper end of the 120 and includes a post fixing bracket 150 to be seated on the upper end of the boundary stone. The post fixing bracket 150 is welded on the upper end of the lower post 120 . That is, after inserting the post fixing anchor bolt 140 in a state in which a hole is machined using a concrete drill on the upper end of the boundary stone, it is fixed with a nut in the state in which the boundary stone fixing anchor bolt is inserted on the post fixing bracket 150 .

The lower post 120 may be configured as a plurality of stepped posts, for example. Specifically, the lower post 120 is stepped with a cross-sectional area smaller than that of the upper lower post on the lower end of the upper lower post and the upper lower post extended along the longitudinal direction on the lower end of the guard rail post 110 . and a lower lower post to which it is coupled. The lower part of the lower post is a part that goes deep into the ground when the guard rail is installed, and there is a risk of deformation when a long pipe is strongly driven, so it is installed in two stages.

The post fixing bracket 150 and the boundary stone of the plurality of guard rail holding modules 100 are coupled through the boundary stone fixing anchor bolts 160, and the plurality of guard rail holding modules 100 and the guard rail 200 are It is bound with the provisional shock absorber 300 interposed therebetween.

The post fixing anchor bolt 140 and the boundary stone fixing anchor bolt 160 are stably fixed on the boundary stone through a wedge-shaped structure coupled to be rotatably operable.

In the state in which the first bolt striking body is driven to a predetermined depth, through the operation of rotating the first nut rotatably coupled to the thread formed on the upper portion of the first bolt striking body, the first bolt striking body is in a state covered with the first bolt striking body. The first wedge pressing body enables rotation of the first wedge fixing body while moving in the downward direction. That is, in a state where the lower end of the first wedge pressing body having a cylindrical shape is in contact with the inclined wedge surface 143 of the first wedge fixing body 142, the rotation of the first nut in contact with the upper end of the first wedge pressing body enables the rotation of the first wedge fixing body by enabling the lower movement of the first wedge pressing body.

That is, through the process of the first wedge pressing body continuously pressing the inclined upper surface of the first wedge fixing body, the first wedge fixing body rotates about the first fixing pin and spreads outward of the first bolt striking body does work. As a result, in a state in which the post fixing anchor bolt 140 is driven on the boundary stone, if the unfolded structure of the first wedge fixing body is maintained, it makes it very difficult to separate the upper part of the post fixing anchor bolt 140, thereby enabling stable fixing. .

When the first nut is tightened, the first wedge pressing body in the shape of a pipe goes down.

As the first wedge pressing body descends, the first wedge fixing body digs into the ground or strongly presses the wall surface of the boundary stone in the process of opening in both directions to prevent the first bolt striking body, which is the fixing bolt, from being pulled upward.

The upper end of the first wedge fixing body constituting the post fixing anchor bolt 140 has an angle and a width of a certain interval, which is to prevent the wedge fixing body from entering into the first wedge pressing body.

A pair of the first wedge fixing body 142 is symmetrically disposed on the first bolt striking body, and specifically inclined on the opposite side of the first pin coupling hole 141b to which the first fixing pin 144 is coupled. In this state, the wedge surface 143 may be formed. The first wedge fixing body 142 is a structure that can move only at a certain angle, and when the post fixing anchor bolt 140 is driven into the fixed position, the wedge surface 143 automatically rises upward, and in this state, the first nut ( In the case of fixing using 146), the first wedge fixing body 142 has a structure in which the first wedge fixing body 142 is fixed by spreading to both sides about the first pin coupling hole 141b through the first wedge pressing body. That is, a pair of first wedge fixing bodies 142 are spread apart on both sides so that a pair of wedge surfaces 143 may form a straight line.

On the other hand, the boundary stone fixing anchor bolt 160 is a second wedge pressing body 165 having a pipe shape, a second bolt striking body 161 having a sharp lower end which is inserted and disposed in the second wedge pressing body 165, A second wedge fixing body 162 rotatably coupled through a second fixing pin 164 coupled through a second pin coupling hole 161b formed on a side surface of the second bolt striking body 161 and the and a second nut 166 rotatably coupled to a thread formed on an upper portion of the second bolt striking body.

The process of fixing the boundary stone fixing anchor bolts 160 on the boundary stone 2 proceeds in the same manner as the post fixing anchor bolts 140 .

The process of fixing the guard rail holding module 100 is as follows.

First, the post fixing anchor bolt 140 and the lower post 120 are fixed on the ground or the boundary stone using a separate machine.

Specifically, after drilling the ground primarily using a core drill, the lower post 120, which is a base post, is buried. In the above state, a second hole is drilled on the lower end of the buried portion of the lower post 120 using a core drill. In the above state, the post fixing anchor bolt 140 is fixed.

Fix the post fixing anchor bolt 140 and the lower post 120 by using a nut to the post fixing anchor bolt 140 using a special tool such as a box connecting rod. That is, through the process of rotating the first nut 146 coupled on the upper end of the post fixing anchor bolt 140 coupled through the lower end of the lower post 120 through the box connecting rod, the first wedge pressing body It enables downward movement and bi-directional flaring of the first wedge fixture.
