Description

Guardrail reinforcement structure and reinforcement unit {REINFORCING STRUCTURE AND REINFORCING UNIT OF GUARD RAIL}

The present invention relates to a guardrail reinforcing structure and reinforcing unit, and more particularly, to a guardrail reinforcing structure and reinforcing unit for reinforcing the existing guard rail or stretched guard rail to prevent derailment of the vehicle. It is about.

In general, guardrails are installed at the shoulders in the middle of the road or on both sides of the road so as not to be derailed, so that the guardrail is separated from the road and collides with the vehicle being removed from the road. In addition, such guardrails are usually installed on mountain roads or winding roads so that vehicles do not fall out of the road, and are installed on the boundary between sidewalks and roadways to protect pedestrians in the city.

In the conventional guardrail as described above, as shown in FIG. 1, the guardrail plate 5 is long mounted on the side of the support 1 installed at equal intervals along the road so that the vehicle traveling on the road is not separated. That is, the guardrail plate 5 supported by the support 1 prevents the vehicle from derailing on the road while colliding with the vehicle that is separated from the road.

The guardrail plate 5 is bent in a zigzag manner as shown in A of FIG.

≪ Embodiment 1 >

First, a first embodiment of a guardrail reinforcement structure according to the present invention will be described.

3 is a perspective view showing the configuration of the guardrail according to the first embodiment of the present invention, Figure 4 is a cross-sectional view taken along the line AA 'of Figure 3, Figure 5 is a view of the guardrail according to the first embodiment Top view. 6 is a plan view showing a modification of the reinforcing material applied to the guard rail according to the first embodiment.

As shown, the guardrail reinforcement structure according to the present embodiment, the hollow pillar 10 is disposed at a predetermined interval along the roadside, and the plate-shaped guard rail plate mounted on the front of the pillar 10 ( It is for reinforcing the guard rail which consists of 20), and consists of the reinforcement 30 and the filler 40.

In this case, the support 10 and the guardrail plate 20 may be used as long as it is responsible for the configuration and function as described above.

The reinforcing material 30 is installed between the adjacent struts 10, each end is inserted into the interior of each strut 10. To this end, the reinforcing material 30 is composed of a connecting portion 31 disposed between the support 10, and the insertion portion 33 is connected to the connecting portion 31 and inserted into the support 10.

In the present exemplary embodiment, the connection part 31 and the insertion part 33 are illustrated as being integrally formed, but as shown in FIGS. 7 and 8, it may be separated. In this case, the connecting portion 31 can be manufactured in a plurality of sizes according to the change in the space between the support posts 10 to correspond to the change in the space between the support posts 10.

In addition, fastening holes 31a and 33b are formed in the connecting part 31 and the inserting part 33, respectively, and the connecting part 31 is fixed with a fixing member 50, for example, a bolt and a nut. 31 and the insertion part 33 can be fixed.

In addition, as shown in FIG. 8, the fastening hole 33b formed at one end of the insertion part 33 may be configured to have a long hole shape in a direction along a roadside in order to correspond to a minute dimensional change. Alternatively, although not shown, the fastening hole 31a formed at each end of the connection part 31 may be configured in a long hole shape.

In addition, in the present embodiment, although the connection portion 31 and the insertion portion 33 is illustrated as being configured in the form of a plate, it may have a structure such as 'c' shape, square tube shape, cylindrical tube shape.

The material of the reinforcing material 30 is preferably a metal material, but may be changed to a material having rigidity such as a high strength synthetic resin material.

In addition, as shown in FIG. 5, the connection part 31 may be configured in a form of connecting the support 10 and the support 10 in a straight line. As shown in FIG. 6, the connection part 31 may be configured in a curved shape to form a guard rail. It may be configured to support the rear end of the plate 20.

In the case of the conventional guardrail illustrated in FIG. 1, the connection part 31 having the same shape as that of FIG. 5 may be in close contact with the rear end of the guardrail plate 20. In this case, the entirety of the connecting portion 31 is in close contact with the rear end of the guardrail plate 20.

However, as shown in FIG. 5, even when the connecting part 31 forms a structure spaced apart from the guard rail plate 20, the guard rail is supported while being in contact with the guard rail plate 20 when the guard rail plate 20 is deformed. The plate 20 can be reinforced.

And the connection portion 31 of the form as shown in FIG. 6 has a structure in which only a part of the connection portion 31 is in close contact with the rear end of the guard rail plate 20, all of the connection portion 31 is in close contact with the rear end of the guard rail plate 20 The structure is also possible.

On the other hand, the filler 40 is filled in the support 10 to reinforce the rigidity of the support 10, and serves to integrate the support 10 and the reinforcement 30. The filler 40 may be used by adopting a variety of materials, it is preferable to use a material that is cheap and excellent in strength.

In more detail, the filler 40 according to the present invention may be a synthetic resin mixed with 50 ~ 70 parts by weight of the wood powder with respect to the polymer resin, 100 parts by weight of the polymer resin. Here, the polymer resin is not particularly limited in kind, for example, polypropylene resin, polyester resin or polyethylene resin may be used.

Alternatively, the filler 40 according to the present invention may be used by mixing 30 to 95% by weight of coal waste stone and 5 to 70% by weight of resin. This is to allow the resin to solidify the coal waste-rock as it is mixed with the coal waste-rock. At this time, if the resin is blended in less than 5% by weight, it is difficult to evenly mix the resin and coal waste-rock, and the coal waste-rock is not partially solidified. Will rise. Therefore, the resin mixed with coal waste-rock is preferably used in the range of 5 to 35% by weight.

In addition, when the coal waste-rock is mixed with the resin to solidify the resin, the resin exhibits the same effect as coating the coal waste-rock to block the inflow of pollutants from the coal waste-rock into the ground.

In this case, various kinds of resins may be used as the resin, but in the present invention, it is preferable that the resin is a polyester resin or an epoxy resin.

Tack drying and curing drying time of the polyester resin or epoxy resin is 30 minutes and 120 minutes at 5 ℃, respectively 20 minutes and 90 minutes at 20 ℃, it takes 15 minutes and 60 minutes at 30 ℃, respectively. Therefore, since it hardens within 2 hours in the usual temperature range, it is possible to significantly shorten the air than when using cement.

In addition, when the coal waste-rock and the resin according to the present invention is mixed and cured, it can express 20 ~ 40% more strength than when using cement.

Here, the coal waste-rock refers to the waste-rock generated during the operation for mining coal, and because the coal waste-rock and the mined coal contain rock, the rock is contained in the excavation process approaching the coal beds buried underground. It is divided into crushed stone which removes it to control quality.

Double crushed stone is a mineral distinguished from shale. The rough rock mineral is composed of fine minerals centered on clay minerals, and has high hardness and foams at a high temperature of 1000 ° C or higher.

The chemical composition of shale minerals is in the range of 20 to 35% by weight of Al ₂ O ₃ , 40 to 60% by weight of SiO ₂ , and 2 to 10% by weight of Fe ₂ O _3. It contains the same as a component. This is somewhat different in proportions, but shale minerals containing Al ₂ O ₃ , SiO ₂ , and Fe ₂ O ₃ , which are the main components of cement, are the main components of the coal.

In particular, due to the high hardness of the hard coal, the hard coal has a characteristic of serving as an aggregate.

In addition, the excavated waste-rock produced during the mining process of coal mines is produced in various ways according to the types of constituent rocks according to the geological characteristics around coal mines, but most of them are composed of sandstone and shale. Here, the shale can be used as a crushed stone for civil engineering because of its relatively high crushing hardness and hard rock, and the sandstone can be used as fine aggregate.

In this way, by utilizing coal waste-rock that contains cement-like components in cement, coarse aggregate and fine aggregate, which are the main raw materials of concrete, and simultaneously plays the role of coarse aggregate or fine aggregate, it reduces the cost of construction by reducing the use of cement, coarse aggregate and fine aggregate. It can be realized.

The coal waste-rock may be processed to have a uniform particle diameter while drying, but this is only to prevent excessive pressure in the stirrer for stirring the coal waste-rock and the resin, and the coal waste-rock may be dried without further processing. Do.

Alternatively, the filler 40 according to the present embodiment may be formed by mixing 50 to 95% by weight of silica sand and 5 to 50% by weight of the resin.

As the resin, a liquid unsaturated polyester resin may be used. The liquid unsaturated polyester resin is an unsaturated polyester resin dissolved in a reactive monomer (mainly styrene monomer), and is a low viscosity liquid resin. The unsaturated polyester resin is a polymer containing an unsaturated bond in the main chain and is obtained by esterifying an unsaturated acid which is a polybasic acid with a polyhydric alcohol. The reactive monomers induce a chain polymerization by radical reaction upon curing to form a three-dimensional crosslinked network structure with an unsaturated polyester resin. By this three-dimensional structure, the polyester resin has excellent heat resistance and corrosion resistance, and turns into an insoluble thermosetting plastic. Currently unsaturated polyester resins are mostly used as a matrix of fiber-reinforced plastics (FRP), it is applied to many fields such as construction materials, transportation equipment, electrical materials.

The unsaturated polyester resin exhibits excellent adhesion with silica sand.

In addition, methyl methacrylate (MMA) resin or urethane binder may be used instead of the unsaturated polyester resin used in the present embodiment.

As used herein, the silica sand is added as a reinforcing material 30 to increase mechanical strength in the thermosetting plastic and also as a filler to prevent cracking.

The filler 40 may be filled in the support 10 before inserting the insert 33 into the support 10, or may be filled in the support 10 after inserting the insert 33. In this case, the filling time of the filling material 40 indicates whether the filling part 40 does not interfere with the filling operation, and whether the filling material 40 is not evenly filled in the support 10 by the inserting part 33. Can be determined in consideration of this.

The guardrail reinforcement structure configured as described above may increase the rigidity of the support 10 by the filler 40 filling the support 10 of the guard rail, thereby preventing the support 10 from bending and breaking.

In addition, the filler 40 integrates the reinforcement 30 inserted into the support 10 with the support 10. Therefore, the insertion portion 33 of the reinforcing material 30 supports the connecting portion 31 without being separated from the support 10, and the connecting portion 31 supports the rear end of the guardrail and receives tension by the collision of the vehicle. Deforms to derail the vehicle.

The gap adjusting part 60 is such that both ends of the width direction of the insertion part 33 is in close contact with the support 10 so that both ends of the connection part 31 are more firmly fixed when the connection part 31 receives an impact from the vehicle. To do this.

Therefore, when the inner diameter of the pillar is the same, the dimensions of the gap adjusting portion 60 may be the same, so the gap adjusting portion 60 is preferably a fixed structure.

However, if there is an error in the inner diameter of the column or not equal to each other, it is preferable that the gap adjusting unit 60 is a flexible structure.

The structure allowing the gap adjusting unit 60 to be stretchable may be configured in various configurations. For example, as shown in FIG. 12, it may be configured as a turnbuckle 61.

In addition, in the present embodiment, the filler 40 is evenly filled in the support 10, and the filler 40 may be prevented from being separated from the insertion part 33 due to the filler 40. One or more through holes 33a through which are passed are formed in the insertion part 33.

Therefore, in the present embodiment, regardless of the filling time of the filling material 40, the filling is easy and the filling material 40 may be evenly filled in the support 10.
