Roadside protection cover {Protection cover for street tree}

The present invention relates to a protective cover installed in the growth area of the roadside tree in the boundary stone, and more specifically, the roadside protection cover is divided into a support plate formed of a recycled synthetic resin material and a buffer cover formed of a soft elastic material to produce a plurality of them. By forming a partition, each support plate and the buffer cover and to ensure a stable and easy coupling between each other, to solve the problems of the existing various roadside protection cover and to further benefit the growth of roadside trees.

In general, roadside trees refer to trees planted along roadways or roadways, and are generally formed to improve the environment such as providing aesthetics of the city, fresh air, and cool shades.

These trees are the greenery that people most easily encounter, and linear greenery that forms the framework of urban greenery, and plays an important role in improving the urban living environment, such as improving the landscape, reducing air pollution and noise pollution, and reducing heat island phenomena.

Currently, 406,500 trees are planted along the roads of Korea, with a total extension of 28,878km, with 25% cherry trees, 24% ginkgo trees, 8% plane trees, and 7% zelkova trees. In addition, the roadside tree, which serves as an ecological pathway connecting the city and nature, is the best alternative to expand the lack of green space in cities where the road occupies 20%, and the roadside tree planted through structures such as various forms of protective cover. Will grow healthier and stronger.

Here, the roadside protective cover as described above is installed to secure the growth area of the roadside tree and to prevent damage from pedestrians and surrounding objects, and to prevent the hardening of the soil to facilitate the absorption of rainwater and to help the smooth circulation of air for optimal development environment To prevent the contamination of cigarette butts and other foreign matter in the growth area of the roadside tree to prevent contamination and to serve to provide a breeding environment of microorganisms to help the growth of the roadside tree.

Such a roadside protective cover is usually made of a spherical graphite cast iron or a steel plate or a rolled steel, etc., the roadside protective cover made of a spheroidal graphite cast iron is a high strength, but easily damaged by an external impact, general It is not suitable for use in coastal areas due to easy corrosion due to painting, and has a disadvantage in that it is difficult to give various colors reflecting characteristics of installation area and road due to its high price.

In addition, since there is no function to adjust the inner diameter corresponding to the size of the tree growing after installation, the size of the inner diameter is designed to the maximum value. It is easy to inflow of polluting the growing area. In addition, as a heavy weight body, the entire surface touches the soil as it is, and at the same time, it squeezes the ground and accelerates the hardening. do.

In addition, the roadside protective cover made of steel plate is firm and can be used in coastal areas by enhancing the corrosion resistance through powder coating after hot dip plating, but it accelerates hardening of the ground by pressing the soil entirely as a weight body and thereby growing tree trees. It has a high price, it is not competitive, and there is no function of adjusting the inner diameter corresponding to the size of the tree growing after installation. It is easy to inject waste such as cigarette butts to contaminate the growth area, even when the roadside support is not installed, the four support installation holes are always open, there is a problem that various foreign matters are easily introduced.

In addition, the roadside protective cover made of rolled steel has good durability, but it is easy to cause corrosion and is not easy to apply in coastal areas. It is difficult to impart, like the other types of roadside protection cover mentioned above, the gap between the roadside base and the inner diameter of the protection cover is large and the support installation hole is always open. It is.

In particular, all of the various types of roadside protective covers as described above have a high risk of being injured when a pedestrian falls down due to the characteristics of a material without buffering force, and are likely to be lost due to theft when the raw material prices soar, and are heavy and bulky. Due to its large logistics costs and poor installation, it is not easy to lose soil and create an environment in which microorganisms that can be beneficial to tree trees can grow, and wide gaps cause plants such as weeds to grow and damage the landscape of the protective cover. To have.

The present invention is to solve the problems as described above, and to produce a four-part lower support plate made of a hard synthetic resin material such as recycled resin and the cushion cover of the soft elastic material correspondingly coupled from the upper side of the support plate, These support plates and the buffer cover is configured to facilitate the mutual coupling,

It is an object of the present invention to provide a roadside protective cover that can reasonably overcome the various problems that the existing roadside protective cover had, and further benefit the growth of roadside trees.

The present invention for achieving the object as described above, a buffer consisting of a split plate of the same shape that is in close contact with the upper portion of the support plate made of a divided object of the same shape that is raised to the ground in the growth range of the roadside tree in the boundary stone. The cover is formed separately, so that the support plate and the buffer cover are installed in the growth range that is the base of the tree,

The support plate is made of hard synthetic resin, the groove portion is formed on one side and the support mounting hole is formed on the other side, the fastening protrusion is formed on the upper surface of the support plate and the support protrusion is formed on the lower surface,

The cushion cover is made of a soft elastic material, forming an elastic portion having an induction groove on one side and integrally forming a stopper having a cutout groove on the other side, forming a fitting protrusion on the bottom and an excellent inlet hole repeatedly arranged on the upper surface. Penetrating through,

In the state where the support protrusion of the support plate is located on the ground, the fitting protrusions of the shock absorbing cover are engaged with the fastening protrusions of the support plate to be coupled to each other, and the side of the support plate, which is the divided object, and the side of the shock absorbing cover abuts along the tree trunk. It is comprised so that it may arrange continuously in all directions.

First, as a preferred embodiment of the roadside protective cover of the present invention, consisting of a four-part support plate 10 and a four-part buffer cover 20 also divided, the support plate 10 and the buffer cover 20 which are these divided objects ) Is the same shape.

At this time, the support plate 10 and the shock absorbing cover 20 may be manufactured in a rectangular shape or a circle on a plane and may be configured as an object of two or three divisions as necessary. However, the reason for the four-split configuration as described above is to minimize the size of the injection mold to reduce the mold manufacturing cost, as well as the transport and handling of the support plate 10 and the buffer cover 20, which is a divided object This is because of the convenience of installation and installation.

The support plate 10 of the roadside protective cover of the present invention is mounted on the inner surface of the boundary stone 100 installed around the base of the roadside 110 planted on the roadside, using synthetic resin such as general ABS. Since the support plate 10 is a component that is concealed from the ground, it may be desirable to reduce the cost of injection as it is manufactured using recycled resin, which is a waste material, so that it can be superior in price competitiveness.

The support plate 10 of the present invention forms an arc-shaped groove 11 on one side, and the other side of the support plate installation hole 12 is formed vertically through the support plate 10. The fastening protrusions 13 and 13 ′ of the arc-shaped recess 11 extended to the center point are projected upward at a predetermined interval, and the fastening protrusions 13 and 13 are disposed on the lower surface of the support plate 10. The support protrusions 14 and 14 'protrude downward in a position corresponding to').

In addition, a plurality of pin holes 15, 15 'are vertically penetrated at both end portions of the support plate 10 as described above, and connecting pieces 16 and 16 alternately disposed at both end portions of the support plate 10. ') Protrudes outward, and the pin holes 15 and 15' are also penetrated through the respective connecting pieces 16 and 16 '. In particular, the support plate 10 has a plurality of vertical fastening holes 17 formed in all directions, and a drainage hole 18 having a predetermined size is continuous between the fastening protrusions 13 and 13 '. They are formed in a row, and the lower surface of the support protrusions 14 and 14 'is formed with a concave groove 19 having a concave shape that is repeated continuously.

Thus, the groove portion 11 is arranged in such a way that the neighboring side ends of the four support plate 10 adjacent to each other of the support plate 10 in the periphery of the roadway, the four division grooves 11 face each other and the circular It is to form a through portion of the inside of the through-hole 110 formed in this way is to be located. In particular, it is important that the groove 11 has an inner diameter large enough to prevent interference even when the roadway is sufficiently grown. The support plate 10 is formed by the recess 11 because it is a concealed component. The penetrating portion is also to prevent the interference between the growth of the tree because the interference with the support plate 10 by the hard synthetic resin material does not occur even when the road is completely grown.

In addition, the support mounting hole 12 has a rectangular slit hole shape toward the roadway, which is to be installed if you want to install a separate support for inducing vertical growth for the roadway 110 in a small or young state The lower end of the support is to act as a guide hole for inserting the ground through the support mounting hole 12, the rectangular shape is intended to induce work convenience by expanding the available width for the installation position of the support. .

In addition, the fastening protrusions 13 and 13 'protrude upwards at a predetermined interval to induce coupling to the upper cushion cover 20 while supporting external pressure acting from the buffer cover 20. The supporting protrusions 14 and 14 'at the bottom minimize the ground area with the ground so that the ground hardens so that the absorption of moisture and the soil do not interfere with breathing. do. Particularly, the rain passage 19 formed on the lower surface of the support protrusions 14 and 14 'serves to prevent rainwater flowing from the top from being accumulated between the support protrusions 14 and 14'. , Rainwater introduced from the outside is to move freely through the rain passage (19) support protrusions (14, 14 ') and to be quickly and effectively absorbed in the ground.

At this time, the drainage holes 18 arranged repeatedly between the fastening protrusions 13 and 13 'play a role in which the rainwater flowing from the upper portion is rapidly absorbed in the ground, while the support plate 10 is directly connected to the ground. By minimizing the contact area to reduce the hardening action of the ground, it serves to minimize the overall weight of the support plate (10).

In addition, the pin holes 15 and 15 'and the connecting pieces 16 and 16' formed on both sides of the support plate 10 are for coupling between the support plates 10 adjacent to each other, and the support plates 10 adjacent to each other. As shown in FIG. 7, the connecting pieces 16 and 16 ′ are alternately disposed at both ends, so that when the side ends are interviewed so that the support plates 10 are adjacent to each other, the connecting pieces 16 and 16 ′ protrude. 8 is overlapped with each other from the bottom of the support plate 10, and the pin holes 15 and 15 'penetrate each other in the vertical direction so that these pin holes 15 and 15' are shown in FIG. When the separate fixing pin 30 is inserted downward as described above, the fixing pin 30 penetrates the ground through the pin holes 15 and 15 'at the same time as the connection in the transverse direction to the supporting plates 10 adjacent to each other. Therefore, the firm fixed installation state of the support plate 10 will be maintained.

At this time, the fixing pin 30 is formed by bending both ends of the metal pin downward, and the fixing pin 30 by using the pin holes 15, 15 'adjacent to each other by the fixing pin 30 of such a shape. It is to be inserted downward, the length of the fixing pin 30 will be designed to be long enough so that the lower end is embedded in the ground to maintain a predetermined fixing force.

In particular, the support plate 10 is a plurality of fastening holes 17 are vertically penetrated, the fastening hole 17 is in the vertical direction with respect to the buffer cover 20 in close contact with the upper portion of the support plate 10. It is formed to maintain the binding force of.

Another configuration of the present invention, the shock absorbing cover 20 is molded using a soft elastic material such as rubber or PVC, so it is light and productive, and at the same time minimizes injuries when a person falls, and has a variety of colors due to the characteristics of the material. It can be expressed and produced in various colors according to the road and surrounding environment.

Like the support plate 10 described above, the buffer cover 20 is preferably made of an object having the same shape of four divisions, and on one side, an arc-shaped guide groove 21 is formed. On the other side, an integral stopper 24 is formed by a circular cutout 23. In particular, the induction groove 21 is formed at the end of the elastic portion 22 to be gradually thinner from the inner side of the buffer cover 20 toward the end, the elastic portion 22 in the induction groove ( 21 is a plurality of incision line 29 is formed in the groove form.

In addition, the bottom of the buffer cover 20, the fitting protrusions 25, 25 'are continuously projected downward at a predetermined interval, the buffer cover corresponding to between the fitting protrusions 25, 25'. The upper surface of the (20) is formed by repeating the excellent inlet holes 26, 26 'of the vertical through, a plurality of fastening pins 27 protruding downward from the bottom of the buffer cover (20) In the center of the stopper 24, a through hole 28 is formed.

Accordingly, if the shock absorbing cover 20 is closely coupled to the supporting plate 10, the four-part guide groove 21 will form a circular through portion facing each other. Is the base of the road 110 is to be located.

At this time, the guide groove 21 is made of an arc-shaped curvature of a smaller dimension than the recess 11 of the support plate 10 described above, so that the circular through portion by the guide groove 21 also has a relatively small inner diameter. The inner diameter of the circular shape by the guide groove 21 will be ideal to have a value corresponding to the minimum circumference of the roadside trees that can be planted on the road.

Therefore, when the shock absorbing cover 20 is combined with a small or small roadside length 110 planted, the end of the guide groove 21 may be formed due to the inner diameter of the through hole generated by the guide groove 21. Since they are so close to the outer circumferential surface of the roadside tree 110, there is no excessive gap between them, and foreign matter such as cigarette butts or garbage cannot be introduced into these gaps.

On the other hand, when the circumference of the base is increased through the growth of the small tree 110 having a small size as described above, interference with the guide groove 21 occurs. When such interference occurs, the guide groove 21 is formed. Is expanded to be in close contact with the outer surface of the tree 110 due to the upward bending of the elastic portion 22, the incision line 29 formed in the elastic portion 22 is the guide groove 21 as described above And the expansion and deployment of the elastic portion 22 serves to make it uniform but without interference.

In addition, the stopper portion 24 formed integrally by the cutting groove 23 as described above is to serve to fix the support so that the young tree 110 grows vertically straight. If the support is not necessary, it is possible to prevent foreign matter from flowing into the inside by an integral stopper 24, and when the support is to be installed upright, the cutting groove 23 is broken by using a knife. If the plug portion 24 is removed and removed, a vertical through hole will be formed, so that the lower end of the support penetrates the plug portion 24 and the support mounting hole 12 of the support plate 10 separated and removed as described above. So that it can be fixed to the ground.

At this time, the center of the stopper 24 is formed with a through hole 28 of the vertical through, the withdrawal hole 28 is to break the cutting groove 23 to remove the stopper 24 The stopper 24 separated by the use of a skewer or awl serves as a working hole to be easily separated and removed from the buffer cover 20.

As described above, the stopper 24 may be opened or closed as necessary, thereby preventing the problem that the cigarette butts, or the like may be damaged due to the installation holes of the support, which are always open as in the related art. It is.

In addition, the fitting protrusions 25 and 25 ′ are in close contact with the inside or the outside of the fastening protrusions 13 and 13 ′ of the supporting plate 10 described above, and the upper and lower couplings are stable to each other, and stable load distribution is performed. As it is responsible for the transmission and, while providing the unity between the support plate 10 and the shock absorbing cover 20, while acting as a guide for inducing coupling to a certain position when assembling each other, the assembly and construction of the protective cover Will be improved.

In addition, rainwater inlet holes 26, 26 'vertically penetrated between the fitting protrusions 25 and 25' as described above allow the rainwater to quickly flow into the ground to be absorbed in the rain when it rains, thereby ensuring stable underground water. Of course, it can help to prevent the overflow of sewage pipes, etc., the inner width of the rain inlet hole (26, 26 ') has a minimum size so that foreign matters such as cigarette butts are not repeatedly introduced, so as to be repeatedly arranged The external appearance can be prevented from being soiled by these foreign substances, and various and beautiful exteriors can be produced according to various shapes and arrangement positions of the rainwater inlets 26 and 26 '.

In addition, the fastening pins 27 protruding downward to the bottom of the buffer cover 20 correspond to each other with the fastening holes 17 of the supporting plate 10, wherein the fastening pins 27 are fastening holes 17. By interlocking or undercut the fastening of the support plate 10 and the shock absorber cover 20 will produce a solid vertical assembly.

Accordingly, when the protective cover of the present invention is installed in the boundary stone 100 in a state where the tree 110 in a relatively young state is planted as shown in FIG. 9, the lower support plate 10 and the upper cushion cover ( The fastening by 20) is to protect the base and the ground of the roadway 110, the elastic portion 22 of the shock absorbing cover 20 is made to fit the minimum circumference of the roadway, so the elastic portion 22 of the end Only a minimum gap is formed between the guide groove 21 and the outer circumference of the roadway.

In this state, as the circumference becomes larger as the roadway 110 grows, the elastic portion 22 is in close contact with the circumference of the roadway as shown in FIG. The gap between the tree 20 and the tree 110 does not occur at all, but does not interfere with the growth of the tree.

In addition, the support plate 10 and the shock absorbing cover 20 as described above are coupled to each of the fastening protrusions 13 and 13 'by the upward fitting protrusions 25 and 25', respectively. 13 'and the space between the fitting protrusions 25 and 25' are formed, thereby creating a high temperature and high humidity environment for the inside of the protective cover of the present invention, so that microorganisms, etc., which are beneficial to plant growth, can grow. At the same time, weeds (26, 26 ') of small size can not grow out of the ground with weeds, etc., because they do not grow. It can be done.

In particular, the rain inlet hole 26, 26 'is designed to have a width smaller than the diameter of the cigarette butt to block foreign matter or garbage such as cigarette butts to the inside of the protective cover at the same time of the buffer cover 20 By forming an inclined portion (not shown in the drawings) of the expansion form toward the upper surface it can be designed so that the inflow of rainwater can be made smoothly.

Therefore, since the support plate 10 made of the divided object is light and easy to handle, the support plate 10 is placed on the inner surface of the boundary stone 100 in the state where the roadside tree 110 is planted and the boundary stone 100 is installed. Placed in all directions and connected to each other by a fixing pin 30 and fixed to the ground, then put a separate buffer cover 20 on the top of the support plate 10, stepping on each other and easy installation is made of high quality Work can be done very quickly.

In addition, the elastic portion 22 of the buffer cover 20 is bent upward with the growth of the roadside tree to prevent the gap between the roadside tree and the protective cover without any obstacle to the growth of the roadside tree to prevent foreign matter into these gaps. Various problems caused by the inflow can be blocked completely.

Such a roadside protective cover of the present invention may be manufactured so that the circular protective cover can be completed by assembling and installing the support plate 10 and the buffer cover 20 of the divided object as shown in FIG. The support plate 10 and the buffer cover 20 of the same shape may be manufactured and used for the upper circular protective cover, and each of the support plate 10 and the shock absorbing cover 20 may be prepared. It should be formed the same as the main configuration of the protective cover in the form of a square.

In addition, if necessary, the assembled state of the support plate 10 and the buffer cover 20 may be manufactured so as to maintain a triangular shape in a plane, in which case the number of divided objects of the support plate 10 and the buffer cover 20 is the same. It would be ideal to have three divisions in shape.
