Abstract

The present invention relates to a grating used to prevent a wild animal invasion; and to a roadkill-preventive road gate using the same. The grating used to prevent a wild animal invasion comprises: a zig-zag bent member which is bent in zig-zags so a longitudinal part and a horizontal part bent diagonally widthwise are sequentially repeated to repeatedly form an isosceles trapezoid, and has a joint hole formed on the flank of the longitudinal part; a flank support member with a joint hole corresponding to the joint hole of the longitudinal part; and a joint device penetrating the joint holes to fasten the zig-zag bent member and the flank support member. The zig-zag bent member and the flank support member are repeatedly arranged and fastened by the joint device so the grating is easily fastened. A maximum tangent circle touching an isosceles trapezoidal gap is larger than a maximum tangent circle touching a rectangular gap, thereby increasing a probability that the foot of a wild animal will be stuck into the isosceles trapezoidal gap. Accordingly, the wild animal can hardly pass the grating. The road gate embedding the grating therein is installed by cutting a road between a main road equipped with a fence and an auxiliary road and embedding the grating. Accordingly, a wild animal is prevented from approaching the main road. Furthermore, an open passage is formed widthwise during an embedding process of the grating, thereby forming an escape route and a passage for a small organism stuck into the isosceles trapezoidal gap. In addition, the grating is mounted on a road without a road cutting process, and an inclined part is formed on both longitudinal ends of the grating so the grating is easily mounted and also functions as a speed hump.

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a grating for preventing intrusion of wild animals and a grill for anti-intrusion and road-

[0001] The present invention relates to a grating for preventing invasion of wild animals and a road kill prevention gate gate to which the grating is applied. First, the grating for preventing invasion of wild animals is folded in a zigzag form and the longitudinal part in the longitudinal direction and the transversely bent part in the width direction are sequentially A zigzag bending member in which an isosceles trapezoid is repeatedly formed; A zigzag folding member and a side support member are repeatedly arranged and fastened by the joint means, including a side support member in contact with the longitudinal portions in a straight line, so that, by an isosceles trapezoidal gap maximum opening larger than the rectangular gap maximum opening, To prevent the wild animals from easily passing through the grating. Next, the road-kill-prevention road surface gate to which this grating is applied cuts off the road surface between the main road and the auxiliary road where the fence is installed and buries the grating Thereby preventing the entrance of wild animals into the main ledge and forming an open passage in the width direction when the grating is buried so as to form an escape opening and a moving passage for the small creatures that have fallen into the gap and place the grating on the road surface without cutting the road surface, By forming an inclined portion at both ends of the length, it is easy to install, Also to be president.

Generally, the grating is used for the lid of the outdoor drainage hole or the lid of the ventilation hole of the underground facility, so that it is possible to ventilate the inflow hole and the ventilation hole with the drainage port and prevent the inflow of the dirt, A plurality of longitudinal bars are welded to form a rectangular grid in a planar shape and are made strong enough to withstand the loads of persons passing over the gratings and vehicles.

These gratings are used for the purpose of preventing intrusion of wildlife roads. Some roads are cut off from roads, such as tangential roads and trench roads in the areas surrounding roads and wild animals, and gratings are installed on the cut roads. The visual sense of disappearance of the wild animals in the grating gap of the grating or the visual rejection of the grating below the gap of the grating and the grating of the grating which is felt when the grating is applied do not exceed the grating provided by the wild animal, Have prevented the load kills.

As described above, the conventional grating is installed on the lid of the outdoor drainage hole or the lid of the ventilation hole of the underground facility, and is designed to prevent infiltration of dirt, A technique of an intrusion preventing grating and a technique of a road surface provided with such a grating are being developed.

For example, in Korean Patent Registration No. 1067734, both ends of a footrest supporting shaft inserted into a hole at the center of a sleeve formed on one side of a pivotal footrest are provided on the frame inner side left wall and right wall, respectively, Shaped concave sleeve supporting surface for supporting the rotation shoe so as to be in close contact with the groove formed in the sleeve at the upper end of the bearing bar supported at the inner front side wall and the rear side wall of the frame, A stopper for restricting the downward rotation angle of the rotary footrest is formed at the upper end of the bearing bar, a spring retaining piece spaced from the side of the bearing bar is formed at one side of the sleeve, both ends of the spring return spring are connected to the spring retaining piece and the bearing bar And a stopper for restricting the upward rotation angle of the rotation shoe so as to meet the spring engagement piece is provided on the side surface of the bearing bar And an environment-friendly anti-invasive road surface structure installed on an access road of a road, characterized in that a spacer provided between the sleeves is installed on a foot support shaft.

In Korean Patent Registration No. 1142778, a locking protrusion having a reverse " T " -shaped cross section is formed on the inner opposite wall surface of the frame, and both ends of a channel bar having a reverse " U " A connecting plate is installed downward from the bottom surface of the seesaw plate positioned between the channel bars, and a clevis-shaped hanger arm formed downward from the channel bars The upper and lower parallel link centers are connected to each other by a hinge pin, both ends of the parallel link are connected by circular pins, the upwardly bent pieces formed on the spring support plate are installed on the hanger arms on one side by bolts, The up-and-down steel plate inserted in the formed rectangular guide hole and guided in the up-and-down direction is formed to be bent downward at both ends of the upper spring seat, And a vertical guide rod inserted into the press-in hole formed at the center of the upper spring seat is inserted into a guide hole formed in the spring support plate through the center of the return spring, And a flat spring portion which is in contact with the end portion of the parallel link of the hanger arm of the hanger arm is provided on the other side of the hanger arm, And an engaging step for restricting the lowering position of the seesaw plate is formed on the steel plate, and an " eco-friendly anti-invasive road surface structure provided on the road access road " have.

1. Registration number / date 1010677340000 (September 20, 2011) 2. Registration number / date 1011427780000 (April 24, 2012)

However, in the case of the "environment friendly anti-invasive road surface structure installed on the road access road" of domestic patent registration No. 1067734 and the environmentally friendly anti-invasive road surface structure installed on the road access road of domestic patent registration No. 1142778, There is a problem that costs due to fabrication and costs due to maintenance and repair increase.

In addition, the conventional grating manufactured for the purpose of the lid of the outdoor drain hole or the lid of the ventilation hole of the underground facility is a welded structure in the form of a predetermined standard in advance, so that when installed on the road for the purpose of preventing intrusion of wild animals, It is necessary to connect a plurality of gratings, which may result in additional processes such as perforation, riveting, welding, etc., and the strength of the connected portion may be lowered to cause breakage. There is a problem in that the road surface of the road to be installed should be broken in accordance with the connected state.

Particularly, when the wheels of the vehicle passing over the grating pass through the connecting portion, that is, when the wheel passes over the grating, the load is concentrated on the transverse connecting portion on the right side where the wheel passes, There is a problem that it is easily broken, and when the connection is made to improve the strength in order to prevent such damage, there is a problem that the cost is rapidly increased.

Conventional gratings for outdoor drain cap and underfloor vent cover are mainly formed with a rectangular gap having a large planar width and a short length. The maximum circle tangent to the inside of the rectangular clearance is a circle corresponding to a short length of the gap The small depth of the grating is so small that the small wild animals do not incur the inconvenience of passing through the conventional grating, and the wild animals can not enter the road There is a problem in that the effect of preventing the leakage is small.

Accordingly, it is possible to easily install the device in accordance with the road to be installed, to make the feet of the middle and large animals fall into the gap of the grating, There has been a need to develop wildlife intrusion prevention gratings and road surface gates that prevent wild animals from easily reaching beyond the grating.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a zigzag bending member that is folded in a zigzag manner and is repeatedly bent in a longitudinal direction and a width direction. A side support member in which a joint hole corresponding to the joint hole of the vertical portion is perforated; A zigzag bending member and a side support member cut by a length corresponding to a length to be installed on the road surface are provided such that the side support members are disposed at both ends of the width, It is installed on the road surface which is as fine as the length, width and thickness of the grating by being repeatedly arranged by the width and fastened with the seam material, so that the intrusion of wild animals is prevented by the way of over the grating.

The width of the horizontal maximum portion is 7.5 to 12.5 cm. The gap between the zigzag bent member and the side support member is an isosceles trapezoidal shape. The diameter of the maximum gap contact with the three sides of the isosceles trapezoid is 7.5 to 12.5 cm. And the side elevation supporting el- eal steel is fastened to the zig-zag bending member at intervals of a width and at both ends of the width of the grating and at a constant width interval so that the isosceles trapezoidal gaps The maximum gap of contact between the legs is larger than the maximum gap of the rectangular gap formed by bending the legs at right angles, thereby enhancing the possibility that the foot of the wild animal falls into the gap and the height of the feet is decreased. So that medium and large wild animals can not easily pass through the grating .

The upper surface of the zigzag folding member is formed as an uneven surface, and the adjacent zigzag folding members form a line-symmetry with respect to the side support members, and are fastened to both ends of the length of the grating, Thereby imparting a sense of heterogeneity to the wild animals on the uneven surface and strengthening the binding force of the adjacent zig-zag bending members.

In addition, a grating for preventing intrusion of wild animals is formed, a groove is formed in the auxiliary road surface connected to the main road with a fence for preventing intrusion of wild animals, and a grating is buried in the buried groove. A grating height support for preventing the wild animals from being loaded in the main road and supporting both ends of the grating length at a certain height from the bottom; and when forming the buried grooves, The support and the grating are buried in succession, and the open passage is formed between the grating and the buried grooves so that the small wildlife moves in the opened passage or the small wildlife falling into the gap of the grating can be released .

In addition, since the grating is mounted on the auxiliary road surface connected to the main road and the inclined portion extending from the road surface to the grating height is formed at both ends of the grating length, the road surface cutting process is not required and installation is easy.

The grating for preventing invasion of wild animals according to the present invention is constructed such that a zigzag bent member and a side support member cut by a length corresponding to a length to be installed on a road surface are repeatedly arranged and arranged by a width to be installed, The structure and the fastening of each structure are simple, so that it is easy to manufacture, manage and repair, there is no separate connection in the longitudinal direction, there is no problem due to the fracture weakness of the longitudinal connecting part, And the grating of the present invention is mounted on the grating.

The diameter of the gap maximum contact between the three sides in the gap of the isosceles trapezoidal shape of the zigzag bending member and the side support member is 7.5 to 12.5 cm and the height of the side height supporting elongated bar is 15 to 20 cm, A wild boar of 20 to 27 cm in length or a wild animal with a foot size of 7.5 to 12.5 cm or less and a leg length of 20 cm or more should be able to pull the foot off the gap and remove the missing foot by itself. It is effective to prevent intrusion of medium and large-sized wild animals by preventing it from being easily removed.

The zigzag bent member is prevented from slipping by the uneven surface of the zigzag bending member while imparting a sense of heterogeneity to the wild animals pressing on the uneven surface. The zigzag bent member is linearly symmetrical with respect to the side support member, The binding force of the adjacent zig-zag bending members is enhanced.

In addition, since the road-kill preventing road surface gate is provided on the auxiliary road surface connected to the main road where the fence is installed, there is an effect of preventing the load kill caused by the intrusion of wild animals into the main road, The open path formed by the grating height support supporting the grating at a certain height can move the small wildlife, or the small wildlife falling into the gap of the grating can escape, which is effective for the ecological movement of small wildlife.

In addition, since the grating is mounted on the road surface without cutting the road surface, and the inclined portion is formed so as to extend to the grating height, it is possible to install the vehicle easily and quickly, There is also an effect.
