Description

Road median and construction method {A MEDIAN STRIP FOR ROAD AND CONSTRUCTION METHOD THEREOF}

The present invention relates to a road divider and its construction method, and more particularly, it is possible to absorb a shock against a light collision of the vehicle to minimize damage to the car body and its own damage, and to directly support the strut on the top of the anchor bolt. The present invention relates to a central separator for roads and a method of construction for easy construction and separation by allowing bolts to be fastened.

In general, the central separator is a structure that separates the reciprocating driveway from four or more roads that run at a relatively high speed, such as a highway, as shown in Figure 1, consisting of a concrete block (1) installed in a certain size in the center of the road It is a structure that allows a vehicle to drive safely by dividing up and down lanes (2, 3).

In addition, in the case of a general national road within four lanes where paper is difficult to secure, as illustrated in FIG. 2, a central separator 15 including a guard rail 11 and a support 13 is installed to allow pedestrian crossing or accidents. Inadvertent traffic accidents caused by driver's carelessness in multiple areas will be prevented.

However, the central separator 15 composed of the guard rail 11 and the support 13 is such that the support 13 is made of a hollow tube made of high-strength steel, and easily bent or broken even in a light contact accident with the vehicle. Even if a light impact occurs, the damage easily occurs, and there is a disadvantage in that damage occurs easily in the vehicle body of the contacting or colliding vehicle.

On the other hand, the central separator 15 composed of the guard rail 11 and the support 13 is driven at least 3-4 anchor bolts on the road surface in order to install one support 13 on the road. As shown in FIG. 2, or as shown in FIG. 2, the asphalt is placed in a state of being buried in advance on the road surface before installation.

However, in the process of constructing the central separator 15 as described above, there is often a case where the spacing between the pillars 13 on which the guard rail 11 is to be installed is not constant, in which case the fastening formed in the guard rail 11 is performed. There is also a disadvantage that the construction method is cumbersome and difficult, such as having to re-perforate the hole or move the position of the support 13 again.

Therefore, the present invention has been invented to solve the disadvantages of the prior art as described above, the problem to be solved by the present invention is to configure the support rod and the guard rod made of a resin material, the end of each guard rod for the support using a spring By installing through a separate joint unit, it minimizes damage to the vehicle body in the event of a light collision with the vehicle, and minimizes the damage by absorbing the impact force by using the elasticity of the resin material and the spring elastic force inside the joint unit. To provide a separator.

In addition, another problem to be solved by the present invention is bolted to the bottom of the support in the fastening hole formed on the top of the anchor bolt in the state in which one anchor bolt is installed by hammering in the correct position with respect to the asphalt road surface of the road By assembling directly, it is to provide a construction method for the central separator for easy road construction and separation.

Road central separator according to the present invention for realizing the above technical problem is at least two pillars formed of a hollow round bar made of a resin; At least one guard rod formed of a hollow round bar based on resin; A joint unit which connects both ends of the tension spring between the connecting ring installed on one side of the support and the connecting bolt provided at the end of each guard rod to install the end of each guard rod with respect to each support. ; And an anchor unit configured to fasten the fastening bolt fixed to the lower end of each strut through a holding cap to a fastening hole formed at an upper end of the anchor bolt, so that each strut is installed perpendicular to the road surface.

The joint unit is a connecting ring installed on one side of each pillar; A nut cover disposed to be supported at each end of each of the guard rods and having a nut groove formed at a center thereof;

A control nut rotatably seated in a nut groove of the nut cover; A rod cap accommodating the nut cover and the adjusting nut to the inside to be fitted to each end of the guard rod, and having a nut hole formed at the center thereof so that the adjusting nut is supported to partially protrude outward; A connection bolt which is fastened to the adjustment nut and has a ring ring integrally formed at a front end thereof; A tension spring connected to the ring ring of the connecting bolt and the connecting ring through rings at both ends; And a rod cover on the guard rod to protect the connecting ring, the rod cap, the connecting bolt, and the tension spring while the outer end is fastened to the guard rod with respect to the post.

The anchor unit has a pointed lower end, a screw is formed along the outer circumferential surface, an anchor bolt is formed on the upper end of the flange, a bolt hole is formed in the center of the upper end; A support cap which is fastened in a state of being fitted at the lower end of the support, and in which a fastening bolt which is fastened to the bolt hole of the anchor bolt is welded downward; And a support plate welded to a lower surface of the support cap.

The construction method of the central separator for the road by hammering the anchor bolt on the road surface of the point to install the support by fastening the hammering bolt to the bolt hole formed on the top of the anchor bolt, and then the hammering bolt Removing and installing the anchor bolt on a road surface; Installing at least two props by fastening the fastening bolts on the support caps to the bolt holes on the anchor bolts; And connecting both ends of at least one guard rod through the joint unit between the respective posts to install the guard rods.

The step of installing the guard rod is fastening a connecting ring on one side of each pillar; Riveting the guard rod and the rod cap by inserting the rod cap together with the nut cover and the adjusting nut at each end of each guard rod; Fastening a connecting bolt to the adjusting nut; Hooking both end rings of the tension spring to the ring and the ring on the connecting bolt; Setting a tension of the tension spring by adjusting a coupling amount of the connection bolt with respect to the adjustment nut; In the state of covering the connecting ring and the rod cap, the connecting bolt and the tension spring through the rod cover, it may comprise a step of installing the rod cover by fastening one end to the guard rod.

As described above, the road median separator according to the present invention has an advantage of minimizing damage to the vehicle body due to the elasticity of the resin material itself in the event of a light collision with the vehicle by configuring the support rod and the guard rod.

In addition, the center separator is connected to the end of each guard rod with respect to the strut through a separate joint unit using a spring, so as to absorb the impact force by the spring elastic force inside the joint unit during a light collision with the vehicle, In addition to minimizing deformation, there is an advantage of minimizing breakage and fracture of the connection of the guard rod to the strut.

In addition, the construction method of the above-described center separator is a state in which one anchor bolt is installed by hammering at an accurate position with respect to the asphalt road surface of the road, the fastening formed at the bottom of the support in the fastening hole formed at the top of the anchor bolt. Direct bolting using bolts has the advantage of easy construction and removal.

In addition, the construction method of the above-mentioned center separator is connected to the end of each guard rod for the support via a separate joint unit using a spring, so that even if an error occurs in the installation interval between each support can be accommodated in the joint unit There is an advantage that can eliminate the disadvantages of the previous, such as re-install.
