Description

A connection structure of boundary stone of road

The present invention relates to a connection structure of road boundary stones, and more particularly, to easily connect road boundary stones with each other in a curved section as well as a straight section of a road, and at the same time, firmly fix the bottom surface and the foundation surface of the road boundary stone. The present invention relates to a curvilinear connection structure of road curbstones, which can be used to construct a curbstone with a solid structure without generating a step between road curbstones.

In general, the boundary stone is used as a landmark and safety means for distinguishing a driveway and a sidewalk or a garden and a sidewalk. In general, a block made of concrete is mainly used, but recently, aesthetics such as a city center or a park are considered. Unlike the boundary stone of concrete block, which is weak in moisture and abrasion, it is a tendency that granite stone boundary stone is used even if the initial cost is considered in consideration of the advantage of saving the aesthetics of the road.

Referring to Figure 1, the boundary stone (1) is formed in addition to the generally flat inner surface (1b) and the bottom surface (1c), the outer surface (1a) is formed of a curved surface rounded top corners to increase the durability of the boundary stone, Improves aesthetics This boundary stone (1) is installed between the sidewalk and the driveway, the general road is used for sidewalks and asphalt (3) and the roadway below, including the sidewalk block (2) and the foundation compaction (4) below It is comprised of the roadway containing the foundation compaction part 5, and the boundary stone 1 is constructed between these sidewalks and the roadway.

Between the driveway and the sidewalk, there is generally a boundary stone of cuboid granite with a length of about 1m for safety and height adjustment. This boundary stone is a structure having a weight of about 150Kg or more, and its construction is usually formed on the boundary of roads and walkways having a straight or curved shape, and then the boundary stone is placed on the non-beam concrete or mortar layer. Repeated construction is followed by laying.

And between the boundary stones are constructed without considering the interval for replacement and repair work due to the partial breakage of the boundary stones generated later. Too large a gap between the boundary walls of the road leads to a poor appearance, so the space between them is finished with white cement mixed mortar.

However, such a conventional road boundary stone construction method is, first, without the means for interconnecting and supporting a heavy road boundary stone, simply by relying on the sense of skilled workers, the horizontal and vertical of the road boundary stone by trial and error method. There is a problem that the appearance of aesthetic failure due to irregular intervals between the road boundary stones and horizontal and vertical misalignment. Second, since the construction is simply placed on the mortar layer in a state that is not connected and supported with each other as described above, there is a problem that displacement occurs when an external force is applied. Third, since the construction is made depending on the sense of the skilled worker as described above, the unskilled worker can not work. Fourth, there is a problem that partial damage occurs due to collision between road boundary stones during construction. Fifth, since the road boundary stone is placed on the mortar layer to some extent, it is difficult to make additional adjustments and filling is impossible. Sixth, there is a problem that the replacement and repair of the road boundary stone due to partial breakage due to road boundary stone engagement is difficult.

In order to solve these problems, a conventional "joint device of a roadside road boundary stone" is disclosed in Korean Laid-Open Patent Publication No. 2000-67469. However, the "jointway jointing device of the sidewalk road" is complicated by the formation process of wood boards, upper and lower insertion grooves, wooden rods and fitting grooves, resulting in a rise in labor costs, and it takes a lot of time to produce a boundary stone. There was a problem. Furthermore, since this is merely attention to the connection between road boundary stones, no action is taken on the coupling structure between the boundary stone and the floor. This has the disadvantage that the boundary stone tends to fall when a force is applied laterally to the boundary stone.

The present invention has been made to solve various defects and problems caused by the connection structure of the conventional road boundary stone in view of the above situation, the object of the present invention is to connect and connect adjacent boundary stones in not only straight road section but also curved road section. As a result of the construction, at the same time, the bottom surface and the base surface of the boundary stone can be firmly combined and fixed to each other, so that the beautiful appearance can be used for a long time without being easily damaged. The purpose of the present invention is to provide a connection structure of road boundary stones, which reduces the number of roads.

Another object of the present invention is to provide a means for interconnecting and supporting heavy road curbstones so that the horizontal and vertical of the road curbstones can be easily matched even if not skilled in construction, resulting in irregular gaps between the curbstones and horizontal and vertical misalignment. The purpose of the present invention is to provide a connection fixing structure for road boundary stones, which does not cause aesthetic defects caused by the aesthetics.

It is still another object of the present invention to provide a connection fixing structure of road boundary stones in which adjacent boundary stones are connected and supported to each other so that no displacement occurs even when an external force is applied, and partial breakage does not occur due to collision between road boundary stones during construction. have.

The object is achieved by the connection fixing structure of the road boundary stone according to the present invention.

The connection fixing structure of the road boundary stone provided according to an aspect of the present invention is a structure for connecting adjacent boundary stones constructed on the base surface between the roadway and the sidewalk to each other, for at least one coupling to the bottom surface of each boundary stone. A structure in which a groove is formed and the coupling member is inserted into the grooves of two adjacent boundary stones to couple the two boundary stones, the coupling member comprising: a connecting plate having a thin and constant length; An insertion rod each formed at both ends of the connecting plate, the inserting rod having at least one boundary end insertion end and at least one base surface insertion end, wherein the insertion rod is provided with respect to the connection plate of the coupling member or the bottom surface of the boundary stone. The position of the insertion rod with respect to is adjustable.

In one embodiment, the bottom surface of the boundary stone is formed with a circular groove having a circular cross section having a constant depth, the connecting plate of the coupling member is provided with guide holes at both ends thereof and the insertion rod is the guide hole You can change the location accordingly.

In another embodiment, the fixing rod further comprises a fixing nut for fixing at a specific position of the guide hole.

In another embodiment, the bottom surface of the boundary stone is formed with a long groove having a cross section of the long long groove at a position close to both sides is formed with a constant depth, the insertion rod is fixed to the connecting plate of the coupling member in the long groove You can change the location at.

The present invention can remove the damaged boundary stone and rebuild it as a new boundary stone because the beautiful aesthetic can be used for a long period of time without being easily damaged by connecting and stacking adjacent boundary stones in not only a straight road section but also a curved road section. It is possible to easily adjust the horizontal and vertical of the road boundary stones even if you are not skilled in construction by providing the means to interconnect and support the road boundary stones. Not only does it occur, but adjacent boundary stones are connected and supported with each other so that no displacement occurs even when an external force is applied, and at the same time, the boundary stone and its floor can be firmly fixed to each other, so that partial breakage occurs due to collision between road boundary stones. There is a special advantage that is not.
