Description

  The present invention relates to a distance marker installed on a road shoulder of a railway or a road, or a shoulder of a river embankment and its installation structure, and more specifically, excellent workability that can be easily installed in combination with a grass protection sheet. It relates to distance markers and their installation structures.

  As shown in FIG. 14, a normal distance marker 100 installed on the shoulder of the track is a triangular pillar-shaped wooden sign with a sharp upper end, and the upper portion 101 of the distance marker is painted in white, and its right angle The number of distances is displayed with black Arabic numerals 102 on the two side faces. The middle part 103 of the distance marker is painted black and the lower part 104 is coated with a preservative. Such a distance marker 100 is installed by embedding the lower half 104 and the lower half of the intermediate portion 103 in the ground of the road shoulder 105.

However, the distance marker 100 has a problem that a series of distance marker installation operations such as a hole digging operation, a lower half embedding operation, and a soil backfilling operation are troublesome and time-consuming, and the workability is inferior. there were.
Further, if the distance indicator 100 is simply installed on the shoulder 105, the weeds that grow on the shoulder 105 make it difficult to see the number 102 indicating the distance number of the upper portion 101 of the distance indicator 100, and the weed is left as it is. There is also a problem that the weeds must be cut regularly because the distance marker 100 may be hidden and invisible.

  On the other hand, an in-tunnel range finder has been proposed in which a first display surface and a second display surface for displaying distance numbers are respectively bent and formed with attachment surfaces for attachment to wall surfaces at both ends ( Patent Document 1).

  This tunnel distance marker is simple in structure and can be easily attached to the wall surface of the tunnel, but it is installed on the shoulders of railroads, roads, or river embankments. It is impossible, and it is impossible to prevent weeds from growing.

Utility Model Registration No. 3160825

  The present invention has been made under the above circumstances, and the problem to be solved is a distance indicator excellent in workability that can be easily installed on a road shoulder or a shoulder by combining with a weedproof sheet so that weeds do not grow. It is to provide the installation structure.

In order to solve the above-mentioned problems, a distance marker according to the present invention is a distance sample body made of a plate-like body having an L-shaped horizontal cross-sectional shape, and a support that supports the surface or / and the back surface of the lower end portion of the distance sample body. And a support that is erected from a fixed portion that is fixed to the installation surface.
In the distance marker of the present invention, it is desirable that the distance specimen and the support are formed of a regenerated synthetic resin such as regenerated PET.

  As a preferable support, a support having an L-shaped vertical cross-section in which a vertical piece-like support part supporting the front or back surface of the lower end part of the distance specimen is erected from one end of a horizontal piece-like fixing part, Examples include a support body in which a support portion formed of a sandwiching piece that supports a distance sample body with a front surface and a back surface sandwiched between the lower end portion and a horizontal plate-shaped fixing portion.

  Further, the distance marker installation structure according to the present invention is the distance marker according to the present invention is installed in a standing posture on the grass protection sheet laid on the installation surface, and penetrates the distance marker support body and the grass protection sheet. It is fixed by a pile driven into the installation surface.

  As in the distance marker of the present invention, a distance sample body made of a plate-like body having an L-shaped horizontal cross-sectional shape and a support portion that supports the front surface and / or the back surface of the lower end portion of the distance sample body are provided on the installation surface. The one provided with a support standing from the fixed part to be fixed has a simple structure for both the distance specimen and the support and is easy to mass-produce, and the surface or / and the back surface of the lower end of the distance specimen in the factory or construction site The support part of the support body can be easily attached and assembled with bolts, nuts, etc., and, like the distance indicator installation structure of the present invention, on the grass protection sheet laid on the installation surface such as the road shoulder or the shoulder The distance indicator of the present invention is installed in an upright position, and it is simply installed and constructed in combination with the weed protection sheet by fixing the distance indicator support and the weed protection sheet with a pile driven into the installation surface. Can do. Therefore, a series of troublesome operations such as digging work, embedding work in the lower half of the distance sign, and earth backfilling work, which were necessary when installing the conventional distance sign 100, are not required. Therefore, the weed-proof sheet prevents weeds from growing around the distance indicator, so that cumbersome and expensive weed cutting operations are unnecessary, and maintenance is facilitated.

  Then, as the support, a support having an L-shaped vertical cross-sectional shape in which a vertical piece-shaped support portion is erected from one end of a horizontal piece-shaped fixing portion is used, and a plate-like body having an L-shaped horizontal cross-sectional shape is used. The support is disposed on the front side and the back side of the lower end portion of the distance sample body, and the front and back surfaces of the lower end portion of the distance sample body are sandwiched between the vertical piece-like support portions of each support body. For example, when the distance specimen is tilted to the front side due to wind pressure or avalanche load acting from the back side of the distance specimen, the L-shaped support on the front side is deformed into an acute angle and its elasticity While the vertical piece-like support part tries to push back the distance specimen by the restoring force, the L-shaped support part on the back side is deformed to an obtuse angle, and the vertical piece-like support part becomes a distance indicator by the elastic restoring force. In order to pull back the main body, the distance specimen is firmly supported so as not to fall down. Therefore, even if a large wind pressure acts on the distance specimen or an avalanche load acts on the distance specimen, there is almost no fear that the distance specimen will fall or break.

  In addition, as a support, a support that is formed by holding a support piece composed of a holding piece that supports the front and back surfaces of the lower end portion of the distance specimen from a horizontal plate-like fixing portion is used. When supporting the front and back surfaces of the lower end portion of the main body, the surface of the lower end portion of the distance sample body is supported when the distance sample body is inclined to the surface side by, for example, wind pressure or avalanche load, as described above. The front side holding piece tries to push back the distance sample body, while the back side holding piece that supports the back of the lower end of the distance sample body tries to pull back the distance sample body so that the distance sample body does not fall down. Since it is firmly supported, there is almost no fear that the distance specimen will fall or break even if a large wind pressure or avalanche load is applied.

  Furthermore, if the distance specimen and the support are made of a regenerated synthetic resin such as a regenerated pet, it will be possible to reduce the production cost and to mass-produce it at low cost, which will greatly contribute to the reuse of resources. Become.

  Hereinafter, a distance marker according to the present invention and its installation structure will be described in detail with reference to the drawings.

  1 is a front view of a distance marker according to one embodiment of the present invention, FIG. 2 is a plan view of the distance marker, FIG. 3 is a rear view of the distance marker, and FIG. 4 is an exploded plan view of the distance marker. As shown in the figure, the distance marker 10 includes a distance sample body 1 and a plurality of (four) support bodies 2 attached and fixed to the lower end portion thereof.

  The distance specimen 1 is made of a white plate-like body having an L-shaped horizontal cross-sectional shape, and is bent at a right angle so as to protrude forward at a bent portion 1a on the center line in the width direction, and this bent portion 1a. Arabic numerals 1c and 1c representing the number of distances are formed of a black paint on the front surfaces (front surfaces) of the side plates 1b and 1b on both sides. And the bolt insertion hole 1d (refer FIG. 4) is perforated | pierced by two at the lower end part of the both-sides board 1b and 1b. The Arabic numeral 1c may be formed by sticking a resin film on which numbers are printed with black ink or a black numeral plate cut out according to the shape of the numbers, to the surfaces of both side plates 1b and 1b with an adhesive or an adhesive. Good.

  The distance specimen 1 is formed of a regenerated synthetic resin such as regenerated PET (polyethylene terephthalate), and is colored white by blending an appropriate amount of a white colorant. The material of the distance specimen 1 is not limited, and may be made of a metal plate such as an aluminum plate, or heat such as high density polyethylene (HDPE), polyvinyl chloride (PVC), or polyethylene terephthalate (PET). Although it may be molded with a plastic synthetic resin, if it is molded with a regenerated synthetic resin such as regenerated PET as in the distance specimen 1 of this embodiment, it becomes possible to reduce the production cost and to mass-produce it at low cost. There is an advantage that can contribute to reuse. In addition, when producing the distance specimen 1 with a metal plate or the like, it is only necessary to apply a white paint and color it white. When molding the distance specimen 1 with synthetic resin or regenerated synthetic resin, as described above. What is necessary is just to mix | blend a white coloring agent and to color white. The distance specimen 1 may be a bent plate obtained by bending a synthetic resin plate or a metal plate into an L shape, or a molded plate extruded or injection molded into an L shape using a synthetic resin, a recycled synthetic resin, or the like. It may be.

  Although the size of the distance specimen 1 is not limited, for example, the height dimension is preferably set to about 550 mm, and the width dimension of the side plate 1b is preferably set to about 150 mm. For example, a large Arabic numeral 1c having a height of about 150 mm and a width of about 80 mm can be displayed on the surface (front surface), and the display position of the Arabic numeral 1c is also high, so that the number of distances can be easily confirmed.

  Further, the thickness of the distance specimen 1 (plate thickness) is not limited, but when the distance specimen 1 is formed of synthetic resin or regenerated synthetic resin, the thickness is preferably set to about 5 mm. Since the mechanical strength of the distance specimen 1 is increased with such a thickness, there is no risk of damage even when a large wind pressure or avalanche load acts on the distance specimen 1.

  The height dimension of the distance specimen 1, the width dimension of the side plate 1 b, the size of the Arabic numeral 1 c, and the like are adjusted to the distance marker dimensions and numeral sizes defined in the track gauge facility standard. Needless to say, you can.

  As shown in FIGS. 1 to 4, the support 2 that supports the distance sample 1 is a vertical piece-like support that supports the front or back surface of the lower end portions of the side plates 1 b and 1 b of the distance sample 1. 2b has an L-shaped vertical cross-sectional shape standing from one end of a horizontal piece-like fixing portion 2a fixed to the installation surface, and the horizontal piece-like fixing portion 2a of the support 2 includes A hole 2c for driving a pile 4 to be described later is formed, and two bolt insertion holes 1d, 1d drilled in the lower end portion of the side plate 1b of the distance specimen 1 are formed in the vertical piece-like support portion 2b. Two bolt insertion holes 2d and 2d (see FIG. 4) that match (see FIG. 4) are perforated.

This support 2 is formed of a regenerated synthetic resin such as regenerated PET, like the distance sample 1, but is not colored white like the distance sample 1, but contains a black colorant. By doing so, it is colored in the same black color as the weedproof sheet 3 described later. If the herbicidal sheet 3 is colored brown or green, a brown or green colorant is blended with the regenerated synthetic resin accordingly, and the support 2 is the same brown or green as the herbicidal sheet 3. It is good to color.
Needless to say, the support 2 may be made of the metal plate or formed of the thermoplastic synthetic resin.

  As shown in FIGS. 1 to 3, the above-described support 2 has both vertical plates 1 b in contact with the lower end portions of the both side plates 1 b and 1 b of the distance specimen 1. , 1b, two on each of the front side and the back side of the lower end portion, and a total of four are arranged. As shown in FIGS. 2 and 3, the horizontal support of the two supports 2, 2 arranged on the back side is provided. The piece-like fixing portions 2a and 2a are stacked one above the other with the positions of the holes 2c for driving the piles. And the vertical piece-like support parts 2b and 2b of the two support bodies 2 and 2 arrange | positioned at the surface side, and the vertical piece-like support parts 2b and 2b of the two support bodies 2 and 2a arrange | positioned at the back surface side. From the bolt insertion holes 2d and 2d (see FIG. 4) of the respective vertical piece-like support portions 2b on the surface side with the lower end portions of the both side plates 1b and 1b of the distance specimen 1 being sandwiched from the front and back, 5a and 5a are inserted into bolt insertion holes 1d and 1d (see FIG. 4) at the lower ends of both side plates 1b and 1b and bolt insertion holes 2d and 2d (see FIG. 4) of the respective vertical piece-like support portions 2b on the back side. By inserting and tightening with the nuts 5b, 5b, the vertical piece-like support portions 2b of the four supports 2, 2, 2, 2 are brought into contact with the surfaces of the lower end portions of the side plates 1b, 1b of the distance sample body 1, respectively. It is firmly attached and fixed to the back, and these supports 2, 2, 2, Range sampling body 1 is supported so as not fall by.

  Thus, if the vertical piece-like support portions 2b of the four support bodies 2 are supported with the front and back surfaces of the lower end portion of the distance sample body 1 sandwiched between them, wind pressure or avalanche load acts from the back surface side of the distance sample body 1. When the distance specimen 1 is inclined to the surface side, the L-shaped support body 2 on the surface side is deformed into an acute angle, and the vertical piece-like support portion 2b pushes back the distance specimen body 1 by its elastic restoring force. On the other hand, the L-shaped support 2 on the back side is deformed to an obtuse angle, and the vertical piece-like support 2b tries to pull back the distance sample 1 by its elastic restoring force, so that the distance sample 1 cannot be tilted. It becomes possible to support firmly. Therefore, the fear that the distance specimen 1 will fall or break due to a large wind pressure or avalanche load is almost eliminated.

In the distance marker 10 of this embodiment, two supports 2 and 2 are attached and fixed to the front and back surfaces of the lower end portion of one side plate 1b with two bolts 5a and 5a and two nuts 5b and 5b. However, it goes without saying that the number of bolts and nuts may be increased or decreased as appropriate.
Further, the means for attaching and fixing the supports 2 and 2 to the front and back surfaces of the lower end portion of the side plate 1b is not limited to the bolt 5a and the nut 5b. For example, bonding with an adhesive or caulking material, ultrasonic welding, etc. Various means can be employed.

  The size and thickness of the L-shaped support 2 are not limited. For example, when the L-shaped support 2 is attached to the distance specimen 1 having a height of about 550 mm, the side plate 1b having a width of about 150 mm, and a thickness of about 5 mm. The width of the horizontal piece-like fixing part 2a of the support 2 attached to the front surface side is set to about 150 mm in accordance with the width of the side plate 1b, the depth dimension (front-rear dimension) is about 100 mm, and the vertical piece-like support part 2b. It is preferable that the height dimension of the support 2 is set to about 100 mm, and the support 2 attached to the back surface side has a horizontal piece-like fixing portion 2a having a width dimension of about 110 mm, a depth dimension of about 125 mm, and a vertical piece-like support. It is preferable to set the height dimension of the portion 2b to about 100 mm. The thickness is preferably set to about 4 to 7 mm for both the front-side support 2 and the back-side support 2. When the support 2 is set to such a size and thickness, and a pile 4 to be described later is driven into the installation surface from the hole 2c of the horizontal piece-like fixing portion 2a of each support 2, the distance indicator 10 is fixed. Even when a load or the like acts on the distance marker 10, the distance sample body 1 can be reliably supported by the four support bodies 2 so as not to fall down, and there is no fear of the support body 2 being damaged.

  For reference, the four support bodies 2 having the above dimensions are attached and fixed to the front and back surfaces of the lower end portions of the both side plates 1b and 1b of the distance specimen 1 having the above dimensions with a total of four bolts 5a and four nuts 5b. The distance marker 10 of the present embodiment was examined for wind pressure resistance performance by applying a load equivalent to a wind speed of 30 m / sec using a load tester. As a result, neither the distance sample 1 nor the support 2 was damaged. It was found that there was no dropout and sufficient wind pressure resistance.

Next, a distance marker installation structure according to the present invention will be described with reference to FIGS.
5 is a front view of the distance indicator installation structure according to the present invention, FIG. 6 is a rear view of the distance indicator installation structure, FIG. 7 is a partial sectional view of a weedproof sheet used in the distance indicator installation structure, and FIG. 8 is a washer. It is a partial front view of the same range marker installation structure which struck a pile through.

  As shown in FIGS. 5 and 6, the distance marker installation structure of the present invention is a weedproof sheet in which the distance marker 10 described above is laid on an installation surface 6 such as a railroad, a road shoulder, or a river shoulder. 3 is installed in an upright position on the board 3, and the pile 4 is installed through the weedproof sheet 3 from the hole 2c (see FIG. 4) formed in the horizontal piece-like fixing part 2a of each support 2 of the distance marker 10. The distance marker 10 is fixed to the installation surface 6 in combination with the weedproof sheet 3 by driving into the surface 6.

The herbicidal sheet 3 is a water-impervious sheet made of a thermoplastic synthetic resin, and exhibits excellent herbicidal function by adding colorants such as black, brown, and green to impart light shielding properties. This is a sheet that can be made. As shown in FIG. 7, the weedproof sheet 3 used in the distance marker installation structure of this embodiment has an appropriate rigidity and bending workability in which a large number of frustoconical convex portions 3a are alternately formed on both surfaces of the sheet. A black embossed sheet having a total thickness (thickness from one convex tip to the opposite convex tip) of 5 to 20 mm from the viewpoints of handleability, rigidity, bending workability, strength, etc. Those having an average thickness of about 0.5 to 1.5 mm are preferably used. As the material resin of the herbicidal sheet 3, various known thermoplastic resins are used, and among them, high density polyethylene (HDPE) having good moldability, stickiness, strength and weather resistance is particularly preferable. Preferably used.
Of course, a synthetic resin flat sheet having a thickness of about 0.5 to 3.0 mm may be used as the weedproof sheet.

  In addition, the pile 4 uses a simple metal saddle-shaped pile as shown in the distance indicator installation structure of this embodiment, but instead of this, a spiral pile (metal iron wire having a high pulling strength) is used. It is also possible to use a spiral pile main body and a "" -shaped pile head integrally formed by bending, and screw them into the installation surface 6.

  In the distance marker installation structure shown in FIGS. 5 and 6, a pile is driven into the peripheral portion of the weedproof sheet 3 to fix the weedproof sheet 3, but the weedproof sheet 3 is not lifted by wind. It is preferable to fix the peripheral part and the intermediate part of the weedproof sheet 3 with the pile 4. Further, if necessary, the fixing strength is further improved by forming a plurality of holes 2c in the horizontal piece-like fixing portion 2a of each support 2 and fixing each support 2 with a plurality of piles 4. It may be.

  Moreover, in the distance marker installation structure shown in FIGS. 5 and 6, the pile 4 is directly driven from the hole 2c formed in the horizontal piece-like fixing portion 2a of the support 2, but the distance marker installation structure shown in FIG. As in the case of the washer 7, the cut piece of the herbicidal sheet 3 may be stacked on the hole 2c of the horizontal piece-like fixing portion 2a, and the pile 4 may be driven from above the washer 7. Then, the fixing strength by the pile 4 is increased, and the distance marker 10 can be installed and fixed more firmly.

  As can be understood from the above description, the distance sample body 1 made of a plate-shaped body having an L-shaped horizontal cross-sectional shape, and fixed to the front and back surfaces of the lower end portion of the distance sample body 1 by bolts 5a and nuts 5b. The distance indicator 10 having four support bodies 2 having an L-shaped vertical cross-sectional shape is simple in structure and easy to mass-produce both the distance specimen 1 and the support body 2 and can be applied to the distance specimen 1 at a factory or construction site. The support 2 can be easily attached and fixed, and the distance indicator 10 stands up on the grass protection sheet 3 laid on the installation surface 6 such as a road shoulder or a shoulder as in the distance indicator installation structure of the present invention. Simply install it in the posture, and fix it with the pile 4 pierced into the installation surface 6 through the hole 2c of the horizontal piece-like fixing part 2a of the support body 2 and drive it into the installation surface 6, and easily combined with the grass protection sheet 3 Can be installed and constructed. Therefore, a series of troublesome operations such as a hole digging operation, an embedding operation of the lower half of the distance marker 100, and a soil backfilling operation, which are necessary when the conventional distance marker 100 is installed, become unnecessary. Therefore, the workability is greatly improved, and the weed-proof sheet 3 prevents the weeds from growing around the distance marker 10. Therefore, the cumbersome and expensive weed cutting operation becomes unnecessary, and the maintenance becomes easy.

  In addition, the distance specimen 1 formed of a plate-like body having an L-shaped horizontal cross-sectional shape is a vertical piece of four support bodies 2 having an L-shaped vertical cross-sectional shape that is fixedly attached to the front and back surfaces of the lower end portion thereof. The support member 2b is firmly supported by being sandwiched from the front surface side and the back surface side. Therefore, even if a large wind pressure or avalanche load acts on the distance sample body 1, the distance sample body 1 falls or breaks. As described above, it can sufficiently withstand the wind pressure of a strong wind of 30 m / sec.

  FIG. 9 is an exploded perspective view of a distance marker according to another embodiment of the present invention in which bolts and nuts are omitted, and FIG. 10 is a plan view of the distance marker.

  The distance indicator 11 shown in FIGS. 9 and 10 includes a distance sample body 1 made of a regenerated synthetic resin having a U-shaped horizontal cross-sectional shape and a reinforcing body 1f made of a regenerated synthetic resin attached to the back surface side. The body 1 is provided with three supports 2 made of regenerated synthetic resin that are attached and fixed with bolts 5a and nuts 5b to the surface of the lower ends of both side plates 1b, 1b and the back of the lower end of the reinforcing body 1f. . The reinforcing body 1f has the same height as the distance sample body 1, and the joining edges 1g and 1g bent forward from the both side ends of the reinforcing body 1f are on the side of the both side plates 1b and 1b of the distance sample body 1. It fits inside the joining edge 1e, 1e bent backward from the end, and is joined with an adhesive. As this adhesive, a urethane-based adhesive suitable for adhesion of a recycled synthetic resin such as recycled PET is preferably used. The joining means of the joining edges 1g and 1e is not limited to an adhesive, and may be joined by means such as joining with a caulking material, welding with ultrasonic waves, and screwing. Further, the reinforcing body 1f may be made of the metal plate, or may be molded of the thermoplastic synthetic resin.

  Since the other configuration of the distance marker 11 is the same as that of the distance marker 10 described above, only the same reference numerals are given to the same portions in FIGS.

  In addition to the same effect as the above-mentioned distance marker 10, the distance marker 11 has a large wind pressure because the strength of the entire distance marker 11 is greatly improved by the reinforcing body 1f attached to the back surface side of the distance sample body 1. Even if an avalanche load is applied, there is a remarkable effect that there is no risk of collapse or breakage.

  11 is an exploded perspective view of a distance marker according to still another embodiment of the present invention, FIG. 12 is a front view of the distance marker, and FIG. 13 is a cross-sectional view taken along line AA of FIG. The structure of the support 20 is different from the support 2 having the L-shaped vertical cross-sectional shape described above.

That is, the support 20 has an L-shaped horizontal cross-sectional shape that is supported by sandwiching the front and back surfaces of the lower end portion of the distance sample body 1 from a circular horizontal plate-shaped fixing portion 20a fixed to the installation surface. A support portion composed of a pair of sandwiching pieces 20b, 20b is erected, and the dimension of the gap between the sandwiching piece 20b and the sandwiching piece 20b is substantially the same as the plate thickness of the distance sample body 1, The height of the piece 20b is set to about 100 mm similarly to the height of the vertical piece-like support portion 2b of the support 2. The horizontal plate-shaped fixing portion 20a is formed with a plurality of (three in FIG. 11) holes 20c into which piles are inserted.
Such a support 20 can be easily manufactured, for example, by injection molding the above-mentioned recycled synthetic resin or thermoplastic resin.

The distance marker 12 is configured such that the lower end portion of the distance sample body 1 having an L-shaped horizontal cross-sectional shape is inserted between the sandwiching piece 20b and the sandwiching piece 20b of the support body 20 from above and the lower end portion of the distance sample body 1 The distance sample body 1 and the support body 2 are not separated unless the distance sample body 1 is artificially pulled upward. However, in order to increase the attachment strength between the lower end portion of the distance specimen 1 and the sandwiching pieces 20b, 20b, it is desirable to fix the lower end portion of the distance specimen 1 and the sandwiching pieces 20b, 20b with an adhesive or bolts and nuts. .
In addition, since the structure of the distance sample body 1 is the same as the above, in FIG. 11-FIG. 13, only the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted.

  As described above, the distance marker 12 supported and fixed by sandwiching the front and back surfaces of the lower end portion of the distance sample body 1 with the holding pieces 20b and 20b of the support body 20 has the distance sample body 1 on the surface side due to wind pressure or avalanche load. Is inclined, the front-side holding piece 20b that supports the surface of the lower end portion of the distance sample body 1 tries to push back the distance sample body 1, and the rear-side holding piece that supports the back surface of the lower end portion of the distance sample body 1 20b tries to pull back the distance specimen 1 and firmly supports the distance specimen 1 so that it does not fall down. Therefore, even if a large wind pressure or avalanche load is applied, the distance specimen 1 is almost never fallen or damaged. Absent.

  Similar to the distance marker 10 described above, such a distance marker 12 is installed in a standing posture on the grass protection sheet 3 laid on the installation surface 6, and is formed on the horizontal plate-like fixing portion 20 a of the support 20. The pile 4 is driven into the installation surface 6 from the hole 2c through the weed protection sheet 3, so that the pile 4 is installed and constructed in combination with the grass protection sheet 3.
