Description

Boundary stone gutter {Apparatus for cut a groove of boundary stone}

The present invention relates to a boundary stone grooving device for forming a luminous groove and a concrete groove in order to increase the luminous function for the boundary stone and the binding capacity with the floor, and more specifically, to improve the identification function. Boundary stone grooving device that not only can form grooved concrete grooves formed on the back and bottom of boundary stone to improve the binding capacity with concrete of the floor in a single work line, but also smoothly process the edges of boundary stones. It is about.

In general, road safety boundary stones are installed on the side of the road as a landmark that separates roads and sidewalks to structurally prevent invasion of vehicles on the sidewalk. Instead of concrete materials that are vulnerable to moisture and abrasion, most of these boundary stones are currently used as boundary stones, which have almost no circular damage and thus can be used for a long time and save the aesthetics of the road.

As such, the boundary stone installed on the side of the road using stone has been used as a construction method in which in most cases, cement mortar is first placed on the floor between the boundary stone and the boundary stone, the boundary stone is leveled on it, and then the concrete is poured again. A boundary stone is to be installed between the road and the asphalt road.

By the way, after installation of road safety boundary stone, concrete is easy to freeze through the use of calcium chloride in winter due to the high absorption rate. Therefore, the conventional construction structure for the boundary stone has a problem that the repair cost caused by the repair work as well as the structural inconvenience of excavating the roadway and sidewalks without any limitation when repairing the boundary stone takes much more than necessary.

In particular, cement mortar and concrete have to be cast more than once because the cement mortar is placed on the floor between the boundary stone and the boundary stone to adjust the horizontal and inclined height of the boundary stone when constructing the boundary stone. As a result of the weakening of the binding state with the boundary stone, the support strength for structurally binding the boundary stone is lowered.

In addition, most kerbstones are inclined or curved at the corners of the roadway to structurally reduce the damage of the tires of the vehicle by the corners of the kerbstones. Apart from the cutting process, the inclined or curved cutting of the edge is additionally performed.

However, the conventional processing method for cutting edges of boundary stones is that the upper cutting wheel is lowered while the boundary stones are mounted on the work line so that the edges of the boundary stones are cut. Even if there was a slight difference in the cutting size of, there could be a structural limitation that the precision of the cutting level could not be made smoothly due to the difference in the cutting degree of the cutting wheels for the edges.

On the other hand, when concrete pours into the boundary stone itself during the concrete placement of the boundary stone on the floor, the binding state of the boundary stone on the floor is naturally increased. Concrete grooves such as luminous grooves on the front should be recessed to the back and bottom of the boundary stone. However, until now, the boundary stone cutting device has not introduced a technology capable of treating such a luminous groove as well as a concrete groove on a single work line.

The present invention was developed in view of the above circumstances, and solves all the inconveniences of the boundary stone structure, which has been cut only in the corner portion or only the luminous groove is formed, as well as structurally with the concrete of the floor in the boundary stone construction process. Not only can the boundary stone shape with concrete grooves, which can be reliably stabilized, be formed on a single work line, but also the edges of the boundary stone can be cut from the bottom, so there is a difference in the cutting size of the boundary stone in the pretreatment process.
