Description

  The present invention relates to a line-of-sight guide support device for attaching and supporting a line-of-sight guide to a concrete wall, a guard rail post, or the like.

  Conventionally, most line-of-sight guides installed on guard pipes, guard rails, utility poles, etc. mainly consist of a round hard resin (polycarbonate or acrylic) lens and a hard resin housing (case). . For installation, mounting using metal fittings such as bands and struts is common. On the other hand, as a line-of-sight guide that is not easily damaged and can be easily attached at low cost, a method of winding a reflective sheet around a support such as a guard rail may be employed. There is also a line-of-sight guidance mark in which a reflective sheet (or reflective material) is affixed to a rubber-based line-of-sight guide support device, a type in which a reflective sheet of a predetermined shape is embedded in the line-of-sight guide support device, The shape of the line-of-sight guide support equipment is also a predetermined shape.

  In addition, in the line-of-sight guidance mark and the line-of-sight guide mounting bracket, the reflector is provided by attaching the inclined plate portion of the mounting bracket to the inclined surface, the inclined plate portion of the main body is provided along the inclined surface, and the reflector is provided. A reflector can be provided by sandwiching between the two body sandwiching portions using a sandwiching portion, and means that can be retrofitted even if the upper surface of the support column is an inclined surface has been proposed.

  However, the line-of-sight guide support equipment for installing the line-of-sight guide on the pillars such as guard pipes, guard rails, and utility poles adapts the sticking surface to the column depending on the diameter of the pillar such as the pillar to be installed. It was necessary to form a shape having a predetermined diameter in advance, or to manufacture a dedicated mounting bracket or the like.

  For example, there are various diameter standards for the pillars, etc. that are to be installed, depending on the roads managed by the national and local governments and other roads managed by business operators. The line-of-sight guide support equipment is manufactured accordingly. Furthermore, there are various sizes and shapes in the reflective equipment (including reflective material) used for the gaze guidance mark. Most of the line-of-sight guide support equipment attached to such a columnar body is made of metal, and the equipment bends due to external forces such as snow pressure and impact. If the equipment is bent, the retroreflective performance is lost because there is no self-restoration. In addition, when the reflective equipment used for the line-of-sight guide is a hard plastic lens, it easily breaks or breaks due to external force, and the retroreflective performance is lost due to cracks or breakage.

  On the other hand, there is a type in which the line-of-sight guide support device is integrally formed of resin or the like, but the type in which the reflective material is embedded in the line-of-sight guide support device or the shape of the line-of-sight guide support device is a predetermined shape. To do. Such a line-of-sight guide support device is designed in accordance with the shape and size of the line-of-sight guide or the shape of a post such as a guard pipe, a guard rail, or a utility pole to be installed.

  In addition, there is also a method of wrapping a reflective sheet around a guard rail or other pillar as a visual guide that is difficult to break and can be easily attached at low cost. May cause sex problems. Also, since the pedestrian side can see the state of being wrapped around a guard rail or other pillar, there are also problems in the landscape when there are many pedestrians, sightseeing spots, etc.

  In the above-described line-of-sight guide support equipment, it was necessary to manufacture it individually to cope with the difference in the size of the pillar to be installed, the shape of the reflector, or the thickness of the reflector. For example, when the line-of-sight guide support device is manufactured by integral molding with resin or the like, it is necessary to manufacture the mold individually. As a result, production costs such as design costs and production costs have been pushed up for the producers to produce products corresponding to each. On the other hand, installers had to deal with many types of line-of-sight guides depending on the various shapes of reflectors, installation targets, etc., which increased construction costs. In addition, maintenance personnel who manage and maintain must have multiple types of inventory as maintenance items, which increases maintenance costs.

  In view of the above-mentioned problems of the prior art, the present invention has a wide range of applications for the shape of structures such as support columns to be installed and the shape of reflectors. It is an object of the present invention to provide a gaze guidance mark support device that is difficult to break even when the gaze is added and the gaze guidance mark is difficult to peel off.

  The line-of-sight guide support apparatus according to the present invention is a line-of-sight guide support apparatus for attaching a line-of-sight guide to an adherend structure. The line-of-sight guide support device has a plate-like structure attachment portion whose bottom surface is fixed in contact with the adherend structure, and a predetermined center portion of the upper surface opposite to the bottom surface of the structure attachment portion. A guide marker support portion having two plate-like portions facing each other at a predetermined interval that rises in an inverted T-shape at a support angle and sandwiches and sandwiches the line-of-sight guide marker from above. The thickness of the structure mounting part changes so that peaks and valleys are formed alternately on the upper surface side of the structure mounting part in parallel with the direction of the guide mark support part. Have a shape to

  According to the gaze guidance mark support device of the present invention, the shape, size, etc. of the gaze guidance mark to be attached can be provided with a width, and the thickness of the structure mounting portion can be changed, and the bottom surface thereof can be changed. Is easy to bend along the mounting surface of the adherend structure, so it can handle a wide range of pillar diameters, such as guardrails and utility poles, and wall surfaces of concrete railings, etc. . As a result, the number of types of line-of-sight guide support equipment manufactured can be reduced, and manufacturing costs, inventory costs, and the like can be reduced. In addition, since the types of line-of-sight guide support materials used for the line-of-sight guide can be reduced, construction costs, maintenance costs, and the like can be reduced.

  Moreover, according to the gaze guidance mark support apparatus of this invention, since it can attach to support | pillars, such as a guardrail of installation object, by simple work, the effort concerning installation work can be reduced. Thereby, construction cost, maintenance cost, etc. can be reduced.

  In addition, according to the line-of-sight guide support material of the present invention, since the main material is manufactured from a flexible thermoplastic elastomer, it is flexible and has restorability. As a result, when the line-of-sight guide is installed on a support such as a guardrail or a utility pole, external force due to a vehicle collision or the like is received, so that damage or the like can be avoided. Furthermore, since it deforms in response to an external force caused by a vehicle collision or the like, and when the external force is released, it automatically returns to its original state, so that labor such as maintenance work can be reduced.

  As described above, the line-of-sight guide support device of the present invention can reduce each cost from the viewpoints of manufacturing, construction, and maintenance.

FIG. 2 is a view showing the structure of the line-of-sight guide support device 1 shown in FIG. 1, and in particular, FIG. 2 (A) is a top view, FIG. 2 (B) is a side view, and FIG. A front view is shown. FIG. 3 is a diagram for explaining the structure of the line-of-sight guide support device 1 shown in FIG. 1, and in particular, FIG. 3 (A) shows a detailed side view shown in FIG. 2 (B). 3B shows a diagram for explaining the shape shown in FIG. Hereinafter, the gaze guidance mark support device 1 will be described mainly with reference to FIGS. 1 to 3.

  As shown in FIGS. 1 (A) and 1 (B), the line-of-sight guide support device 1 is a device for attaching the line-of-sight guide mark 2 to the adherend structure 5 (shown in FIG. 6). The line-of-sight guide mark 2 to be attached is a reflection device (a delineator) and is a sign for guiding the line of sight of a driver such as a vehicle traveling on a road. The adherend structure 5 is, for example, a guard pipe, a guard rail, a guard fence, a support pole such as a utility pole, a wall surface of a concrete railing, or the like. When the driver is traveling toward the vehicle facing direction X # 1 or X # 2, light such as headlights is retroreflected to the line-of-sight guide 2, so that the driver has a guardrail or the like. You can call attention.

  The line-of-sight guidance mark support device 1 includes a guidance mark support portion 11 and a structure attachment portion 12 as shown in FIG. The arrangement direction Z of the guide mark support portion 11 with respect to the structure attachment portion 12 is a direction perpendicular to the directions X # 1 and X # 2, as shown in FIG.

  The guide mark support part 11 further includes a sandwiching part 111 having two plate-like portions facing each other at a predetermined interval (U # 1) for sandwiching the line-of-sight guide sign 2 from above and sandwiching the structure. And a connection support portion 112 that rises in an inverted T shape at a predetermined support angle from the bottom surface of the portion 12 and the central portion of the upper surface on the opposite side.

  As shown in FIGS. 3 (A) and 3 (B), the sandwiching part 111 of the guide mark support part 11 faces at a predetermined interval U # 1 that sandwiches the line of sight guide sign 2 from above. It is formed so as to have two plate-like portions. The width W # 2 of the U-shaped portion of the sandwiching portion 111 is assumed to be larger than the predetermined interval U # 1. As shown in FIG. 3B, the groove depth U # 2 of the U-shaped portion of the sandwiching portion 111 and the height H # 2 of the U-shaped portion of the sandwiching portion 111. is there.

  As will be described later, since the main molding material of the line-of-sight guide support device 1 is a thermoplastic elastomer, the sandwiched portion 111 can be easily expanded by the U-shaped portion, and the thickness of the predetermined line-of-sight guide mark 2 is increased. It can be flexibly deformed in the range of (plate thickness). As a result, the line-of-sight guide mark 2 can be easily sandwiched, and since it acts so that an elastic force is applied in the direction of bonding the adhesive or the like, it can be adhered stably. 2 is difficult to peel off. In addition, since the U-shaped portion can be easily expanded, it is possible to sandwich a wide range of thicknesses of the line-of-sight guide mark 2.

  The connection support part 112 is a structural part that connects the guide mark support part 11 and the structure attachment part 12. The connection support portion 112 is formed so as to rise in an inverted T shape at a predetermined support angle from a central portion of the top surface opposite to the bottom surface of the structure attachment portion 12. As shown in FIG. 3B, the height H # 1 of the portion forming the inverted T-shape of the guide mark support portion 11 is shown.

  In this embodiment, the predetermined support angle is around 90 degrees. In this case, the predetermined support angle = about 90 degrees is an angle at which the attached line-of-sight guide 2 obtains sufficient reflection performance in the front-facing directions X # 1 and X # 2 in the vehicle traveling direction. As shown in FIG. 1A, the line-of-sight guidance mark 2 having a reflective material is attached to the line-of-sight guidance mark support device 1 so as to face the facing directions X # 1 and X # 2. In addition to the present embodiment, for use in vehicle traffic from one direction (X # 1 or X # 2), a reflective material may be used only in one direction. Further, in the line-of-sight guidance target support device 1 for such use, a predetermined support angle may be formed in a range of 60 degrees to 90 degrees in advance.

  As shown in FIGS. 3A and 3B, the connection support portion 112 is formed in a curved shape so as to be thinner than the width W # 2 of the guide mark support portion 11, for example. Hereinafter, the curved structure S # 1 in the connection support portion 112 shown in FIG. 3A is referred to as a hinge structure.

  The line-of-sight guidance mark support device 1 has the above-described hinge structure so that the thickness of the connection support portion 112 is changed to the width W of the guidance mark support portion 11 when the connection support portion 112 is bent by an external force such as contact or impact of the vehicle. The external force can be more dispersed compared to the case of forming the same size as # 2. As a result, as compared with the case where the thickness of the connection support portion 112 is formed to be approximately the same as the width W # 2 of the guide mark support portion 11, the line-of-sight guide mark support device 1 is easily bent, thereby causing stress in other portions. Since (pulling force) is reduced, the peeling force (peeling force) applied to the structure attachment portion 12 when the adhesive is installed is also reduced.

  In FIG. 2, the upper surface of the structure mounting portion 12 is the surface on the side from which the guide mark support portion 11 shown in FIG. 2A protrudes, and the bottom surface of the structure mounting portion 12 is the opposite surface. . Further, the arrangement direction Z shown in FIG. 1A corresponds to the horizontal direction shown in FIG. 2C, and the cross section perpendicular to the arrangement direction Z corresponds to the cross section shown in FIG.

  The structure attachment portion 12 has a plate-like structure in which the bottom surface is fixed in contact with the adherend structure 5. The structure attachment portion 12 further has a concavo-convex structure including a plurality of crest (convex) portions 121 and trough (concave) portions 122. As shown in FIG. 2 (B), this uneven structure has peaks 121 and valleys 122 formed alternately on the upper surface side of the structure mounting portion 12 in parallel with the arrangement direction Z of the guide mark support portion 11. In this way, the thickness of the structure mounting portion 12 is changed. 2 (B) is indicated by a solid line at the corresponding position in FIG. 2 (A), and the valley 122 (center) shown in FIG. 2 (B) is shown in FIG. It is shown by a one-dot chain line at a corresponding position in (A).

  Specifically, as shown in FIGS. 3A and 3B, the uneven structure shown in FIG. 2 is such that the thickness t # 1 of the peak 121 is greater than the thickness t # 2 of the valley 122. Is also formed thick. Further, both end sides of the width W # 1 of the structure attachment portion 12 are valleys 122, arranged so that the valleys 122 and the peaks 121 are alternately repeated toward the center side, and the center side In the connection part (root part) of this connection support part 112, it arrange | positions so that it may become the trough part 122, and is formed in parallel with the arrangement direction Z of the guidance mark support part 11. FIG.

  As shown in FIGS. 1 to 3, a plurality of corrugated peaks 121 and troughs 122 are provided on the upper surface of the structure mounting portion 12, but the embodiment is limited to the corrugated shape. Alternatively, the corrugated shape is not necessarily required if the thick concavo-convex molds (thick part and thin part) are alternately arranged. Further, the number of the mountain parts 121 and the valley parts 122 is not limited to the number shown in the figure.

  Due to the concavo-convex structure of the plurality of peak portions 121 and valley portions 122, for example, a plurality of bent portions P # 1 to P # 6 can be provided as shown in FIG. Thereby, the plate-shaped part of the structure attachment part 12 has the outstanding flexibility.

  If the structure mounting portion 12 does not include the peak portion 121 and the valley portion 122 as shown in FIG. 3A, the stress when the structure mounting portion 12 is bent by the sticking installation. , The degree of bending of the connection portion (base portion) between the structure mounting portion 12 and the connection support portion 112 is the highest, and stress is concentrated on the portion. On the other hand, by providing a plurality of crests 121 and troughs 122 shown in FIG. 3 (A), in each of the bent portions P # 1 to P # 6 of the structure mounting portion 12, along the diameter of the column. And bend. Thereby, the stress at the time of the structure attachment part 12 by sticking installation bending can be disperse | distributed to multiple. Accordingly, the burden on the base portion of the connection support portion 112 on the center side is reduced.

  In addition, due to the excellent bendability of the plurality of peaks 121 and valleys 122 as described later, the adherend surface of the adherend structure 5 to be installed is flat or has a wide range of column diameters. Even a curved surface can be flexibly bent and attached to the attachment surface of the adherend structure 5 to be installed. Further, the bent portions P # 1 to P # 6 having the concavo-convex structure can also disperse stresses such as shearing force and peeling force acting on the structure mounting portion 12.

  Further, in the cross section perpendicular to the arrangement direction Z of the guide mark support portion 11, preferably, the bottom surface of the structure mounting portion 12 has a predetermined diameter Rs having a center on the lower side as shown in FIG. It is formed in a circular arc shape. Thereby, the flexibility of the plate-shaped part of the structure attachment part 12 can be improved further. Therefore, due to this excellent flexibility, when the attachment surface of the adherend structure 5 to be installed is a curved surface such as a column, the circle of the structure mounting portion 12 can be applied to a wider range of column diameters. The bottom surface along the arc shape can be familiarized and pasted. On the other hand, even when the adherend surface of the adherend structure 5 to be installed is a flat surface, the bottom surface along the arc shape of the structure mounting portion 12 is flexibly and closely adhered by an appropriate pressing force. Can be easily attached. The predetermined diameter Rs may be determined in consideration of the application range such as the diameter of the column to be installed.

(Main molding material)
The line-of-sight guide support device 1 has the structure as described above, and is formed by, for example, extrusion molding using a thermoplastic elastomer as a main molding material.

  The line-of-sight guide support material 1 uses thermoplastic elastomer (TPE) as a main molding material, and is formed by extrusion or the like so as to have the above structure. For example, the main molding material of the thermoplastic elastomer is olefin-based TPE / styrene-based TPE / vinyl chloride-based TPE / urethane-based TPE / polyester-based TPE / polyamide-based TPE.

  According to the line-of-sight guide support device 1, since it is formed of a thermoplastic polyurethane elastomer having flexibility and elasticity so as to have the above-described structure, it is flexible and has a restorability. For this reason, the line-of-sight guide support device 1 can be easily expanded by the U-shaped portion of the sandwiched portion 111 and can be flexibly deformed within the range of the thickness (plate thickness) of the line-of-sight guide 2. Can do. Accordingly, the line-of-sight guide mark 2 can be easily sandwiched and acts so that an elastic force is applied in the direction in which the adhesive or the like is adhered, so that it can be stably adhered and hardly peeled off even after the adhesion. Since the U-shaped portion can be easily expanded, it is possible to sandwich the thickness of the line-of-sight guide mark 2 in a wide range.

  In addition, even when the line-of-sight guide support device 1 is installed on the adherend structure 5 and receives an external force due to a vehicle collision or the like, the external force is circulated, so that it is possible to avoid dropping or damage. Further, the line-of-sight guide support device 1 is configured such that the angle formed between the structure mounting portion 12 and the guide-target support unit 11 with respect to the pressure applied to the plane on which the line-of-sight guide target 2 of the guide target support unit 11 is attached is the support angle. When the connection support 112 is bent so as to be smaller and the pressure is released, the connection support 112 is restored to the original support angle. As a result, labor such as repair and construction work can be reduced.

  Specific examples will be described below with reference to the drawings.

(Example 1)
FIG. 4 is a diagram illustrating an example of sticking of the reflective material to the line-of-sight guide support device 1. In FIG. 4, a broken line portion M # 1 shows the pinched portion 111 of the guide mark support portion 11 in an enlarged manner.

  When the line-of-sight guide mark 2 is clamped to the clamping part 111, the pair of left and right flat plates of the clamping part 111 are formed in a U-shape, so that the U-shaped part can be easily expanded. , The line-of-sight guide mark 2 in a predetermined thickness range can be sandwiched. At this time, as shown in FIG. 4, the adhesive 3 or the like is applied to the clamping part 111 so that the line-of-sight guide mark 2 can be easily clamped, and an elastic force is applied in the direction in which the adhesive 3 or the like is bonded. Because it acts on the surface, it can be adhered stably. Moreover, since it sticks with the flat plate on either side of the clamping part 111, the gaze guidance mark 2 cannot peel easily after sticking.

  As described above, since the sandwiched portion 111 can easily expand the U-shaped portion, the thickness of the line-of-sight guide 2 can be sandwiched corresponding to a wide range of thicknesses. Further, the line-of-sight guide mark 2 can be sandwiched and firmly adhered.

  Next, an example of the reflecting material of the line-of-sight guide mark 2 shown in FIG. 4 will be described.

  For the line-of-sight guide support device 1, for example, a microprism sheet having a structure in which a metal vapor deposition layer is disposed on the back side of the microprism layer is used as a reflective material (reflection sheet 22) of the line-of-sight guidepost 2. The microprism sheet is thin, flexible, and has a high retroreflectance. In general, a sheet or plastic lens using glass beads is thicker than the above-described microprism sheet, is liable to crack when bent, and has poor line-of-sight inductivity. Note that a single-layer microprism sheet is less susceptible to cracking when bent than a multi-layer structure.

  FIG. 4 is a view showing an example of the reflection sheet 22 (microprism sheet) having a single-layer structure, and is an explanatory view of sticking the line-of-sight guide 2 to the line-of-sight guide support device 1 (shown in FIG. 1). is there.

  As the line-of-sight guide mark 2, for example, a reflection sheet 22 having a desired size and shape is used. The reflection sheet 22 is made of a retroreflecting material that reflects light so as to have visibility, and is a microprism sheet having a single layer structure, for example.

  For example, a typical microprism sheet has a metal vapor deposition layer disposed on one side of the microprism layer as the reflection sheet 22, and a colored layer (or non-colored) and a substrate layer on the other side of the microprism layer. The resin layer is positioned. This colored layer may be integrated with the microprism layer by performing a thick casting for forming the microprism layer, or by attaching a resin protective coating (or resin film) separately from the microprism layer. It may be provided.

  The resin layer plays a role of protecting the microprism layer, and by coloring or non-coloring the resin layer, the color tone of the metal vapor deposition layer can be changed to gold or silver. In addition, you may provide a vapor deposition base layer in order to ensure adhesiveness between a microprism layer and a metal vapor deposition layer. A protective coating layer for protecting the surface of the reflective material is further provided on the resin layer.

  The thickness of the reflection sheet 22 is not particularly limited, but is usually about 0.1 to 2 mm, for example. The reflective sheet 22 is preferably thin in the above range from the viewpoint of bending performance and impact performance. When the reflective sheet 22 has an adhesive layer, the release paper of the reflective sheet 22 is peeled and removed, and is then pressed and pasted to the outer surface of the plate 21 shown in FIG. The plate 21 is, for example, polycarbonate. The thickness of the plate 21 is not particularly limited, but in the example shown in FIG. 4, a thickness that is the same as or thinner than the plate-like interval U # 1 of the sandwiching portion 111 is preferable.

  In this way, the reflection sheet 22 is pasted on both surfaces of the plate 21 in advance, and the plate 21 is used as the line-of-sight guide mark 2, and the adhesive 3 (or adhesive) or the like is applied to the surface of the sandwiched portion 111 of the line-of-sight guide support material 1. Affix it. Even when the thickness of the line-of-sight guide mark 2 combined with the plate 21 and the reflection sheet 22 is larger than the plate-like interval U # 1 of the sandwiched portion 111, the U-shaped portion of the sandwiched portion 111 is flexible. The line-of-sight guide mark 2 can be sandwiched.

  As described above, even if a physical force from the outside acts on the guidance mark support portion 11 of the line-of-sight guidance mark support device 1, since it has a hinge structure, the guidance mark support portion 11 is flexibly deformed, and the plate There is no possibility that the reflective sheet 22 affixed to 21 will be damaged. Further, by using the reflection sheet 22 of a micro-prism sheet having a single layer structure as the line-of-sight guide mark 2, it is strong against water entering / cracking / breaking, etc., and strong against impact. Therefore, when the gaze guidance mark support device 1 to which the gaze guidance mark 2 is affixed is installed on a guard rail or the like, for example, cracking, breakage, or the like due to snow pressure or impact during vehicle contact can be avoided.

(Example 2)
FIG. 5 is a diagram showing another example in which the visual guidance indicator 2 is attached to the visual guidance indicator support device 1.

  FIG. 5A shows a front view of the visual guidance indicator support device 1A having a length L # 1 to which the visual guidance indicator 2A is attached, and FIG. 5B shows a length L # to which the visual guidance indicator 2B is attached. The front view of 2 gaze guidance mark support equipment 1B is shown. 5A and 5B, the concavo-convex structure of the peak portion 121 and the valley portion 122 is not illustrated. The length L # 1 of the line-of-sight guide mark 2A is several times longer than the length L # 2 of the line-of-sight guide mark 2B, and the heights H # 1 of the lines are the same.

  In FIG. 5A, the shape of the line-of-sight guidance mark 2A is a trapezoid, the length of the lower base of the trapezoid is approximately the same as L # 1, and the length of the upper base of the trapezoid is shorter than L # 1. A trapezoidal reflection sheet 22 is attached to both sides of a trapezoidal plate 21 corresponding to the dimension on the line-of-sight guide mark 2A.

  Also, in FIG. 5B, the shape of the line-of-sight guide mark 2B is a rectangle, and one side of the rectangle is approximately the same as L # 2, for example, the other side is longer than L # 2. A rectangular reflection sheet 22 is attached to both sides of a rectangular plate 21 corresponding to the dimension on the line-of-sight guide 2B.

  Since the line-of-sight guide support device 1 can be manufactured by extrusion molding, the length L of the line-of-sight guide support device 1 according to the line-of-sight guides 2A and 2B as shown in FIGS. 5 (A) and 5 (B). The line-of-sight guide support devices 1A and 1B corresponding to # 1 and L # 2 can be manufactured by cutting from the extruded product. That is, the line-of-sight guide support equipment 1A, 1B corresponding to the line-of-sight guide 2 of various shapes and sizes can be obtained by simple processing such as cutting or fusing from one type of line-of-sight guide support equipment 1 molded product. Etc. can be produced.

  5A and 5B are examples, and the shape and size of the visual guidance indicator 2 shown in FIG. 5 and the length and height of the visual guidance indicator support equipment 1 are limited. is not.

  As described above, the line-of-sight guidance mark support device 1 (1A, 1B) has a structure that can handle the shape and size of the line-of-sight guidance mark 2 (2A, 2B) to be affixed. The number of production types can be reduced, and production costs, inventory costs, etc. can be greatly reduced.

FIG. 6 is a diagram for explaining the adherend structure 5 that is the installation target of the line-of-sight guidance mark support device 1 (1C). In particular, FIG. 6A shows a cross section in which the adherend structure 5 has a strut diameter R # 1, and similarly, FIG. 6B shows a cross section of the strut diameter R # 2. 6 (C) shows a cross section of the column diameter R # 3, and FIG. 6 (D) shows a cross section of the side wall of the adherend structure 5 of the concrete structure. In addition, the diameter of a support | pillar shall differ in a magnitude | size order of R # 1> R # 2> R # 3.

  Here, specifically, as an example, in the shape of the line-of-sight guidance mark support device 1 shown in FIG. 3B, the height H # 1 of the guidance mark support part 11 = 12.5 mm and the width of the sandwiching part 111 W # 2 = 8 mm, the distance U # 1 = 2 mm between the left and right plates of the sandwiching portion 111, the groove depth U # 2 of the U-shaped portion of the sandwiching portion 111 = 5 mm, the width of the sandwiching portion 111 The height of the character-shaped portion is H # 2 = 6 mm. Further, the width W # 1 of the structure mounting portion 12 is 40 mm, the thickness t # 1 of the mountain portion 121 is 3 mm, and the thickness t # 2 of the valley portion 122 is 1.7 mm. The diameter Rs = 95 mm.

  As an example of the installation target of the line-of-sight guide support device 1C, the diameter R # 1 of the support 5A shown in FIG. 6A is 114.3 mm, and the diameter R # 2 of the support 5B shown in FIG. 6B is 89.1 mm. , The diameter R # 3 of the column 5C shown in FIG. 6C is 60.5 mm. Note that the specific dimensions of the line-of-sight guide support device 1C and the example of the diameter of the support shown in FIG. 6 are merely examples, and are not limited to this example.

  In the structure attachment portion 12, the portion where the bending occurs is an uneven structure that can be easily bent, so that the line-of-sight guide support device 1 can be attached to the adherend structure 5 to be installed.

  Specifically, in the line-of-sight guide support equipment 1C, as shown in FIGS. 6 (A) to 6 (C), for example, by setting a predetermined diameter Rs = 95 mm, a support such as a guard pipe, a guard rail, A wide range of struts such as the diameter R # 1 = 114.3 (mm) of the pillar 5A, the diameter R # 2 = 89.1 (mm) of the pillar 5B, and the diameter R # 3 = 60.5 (mm) of the pillar 5C. The bottom surface along the arc shape of the structure mounting portion 12 can be fitted to and adhered to the diameter.

  In addition, as shown in FIG. 6D, the line-of-sight guide support material 1C has a flexible bottom surface along the arc shape of the structure mounting portion 12 by a suitable pressing force on a wall surface such as a side wall of a concrete rail 5D, for example. Since it bends and adheres, it can be attached easily. In addition, when the beam part of a guardrail, etc. are installation targets, it can be considered that the mounting (sticking) surface is substantially flat and corresponds to FIG.

  In FIG. 6 (A) thru | or FIG. 6 (D), it has shown in the state before sticking the gaze guidance mark 2 and the gaze guidance mark support apparatus 1C for the comparison. When actually installed, the installer or the like applies an appropriate force to the top surface of the structure mounting portion 12 so that the bottom surface of the structure mounting portion 12 is along the bonding surface of the adherend structure 5. Since it is deformed and pasted, the bottom surface of the structure mounting portion 12 is in close contact with the pasting surface of the adherend structure 5.

  As described above, in the cross-section (shown in FIG. 6) perpendicular to the arrangement direction Z of the guide mark support portion 11, the bottom surface of the structure mounting portion 12 is on the lower side along with the uneven structure on the top surface of the structure mounting portion 12. Is formed in a circular arc shape with a predetermined diameter Rs having a center at the center, so that the bottom surface of the adherend structure 5 can be easily adapted to the surface of the adherend structure 5. The line-of-sight guide support device 1 (1C) can be attached (attached). Accordingly, a wide range of installation targets can be covered with one type of visual guidance indicator support device 1 (1C).

(Example 4)
FIG. 7 is a diagram illustrating an example of attachment of the line-of-sight guidance mark support device 1.

  In the example of the sticking installation, the structure attaching portion 12 of the line-of-sight guide support device 1 is used as the bottom surface, and the bottom surface is stuck using the fixing means so that the bottom surface is in contact with and fixed to the adherend structure 5. .

  Specifically, in a state where the line-of-sight guide mark 2 is affixed to the line-of-sight guide support device 1, the installer / maintenance person, for example, double-sides the bottom surface of the structure mounting portion 12 from the direction of the dashed arrow in FIG. The line-of-sight guide support device 1 is attached to the adherend structure 5 with an adhesive tape 4 or the like. Preferably, an adhesive or the like is applied to the peripheral area of the double-sided pressure-sensitive adhesive tape 4 in order to further prevent the dropout. In the example shown in FIG. 7, the adherend structure 5 is a column, and the column has a diameter R # 4.

  In sticking installation, the bottom surface of the structure mounting portion 12 flexibly adapts to the sticking surface of the adherend structure 5 due to the excellent flexibility in the structure mounting portion 12 of the line-of-sight guide support device 1 as described above. The line-of-sight guide support device 1 can be easily attached to the adherend structure 5. Thereby, a construction worker, a maintenance person, etc. can perform installation (attachment) easily by simple work.

  As described above, the line-of-sight guide support device 1 can be attached to the adherend structure 5 to be installed by a simple operation, so that the labor required for the installation operation can be reduced. As a result, construction costs, maintenance costs, etc. can be reduced.

  In addition, in the case of the above-mentioned sticking installation, it is preferable that the fixing means of sticking installation is an adhesive or / and an adhesive which can apply | coat or stick to the bottom face of the structure attachment part 12, for example. When an adhesive is used, it is often installed in the form of a double-sided adhesive tape 4. In this case, the double-sided adhesive tape 4 is attached to the bottom surface of the structure mounting portion 12 in advance (peeling of release paper or the like). Covered with a sheet), the double-sided adhesive tape 4 can be applied on site.

  Examples of the adhesive include a butyl rubber adhesive and an acrylic adhesive. Examples of the adhesive include epoxy-based, synthetic rubber-based, and epoxy-modified silicone-based adhesive. In order to improve the adhesion by the adhesive or the adhesive, the bottom surface of the structure attachment portion 12 may be treated with urethane or other primer. By applying the primer treatment, vibrations due to wind pressure, strong wind, rain pressure, etc. are reduced, and firm fixation against expansion and contraction due to heat can be achieved. Moreover, you may use combining an adhesive and an adhesive agent.

FIG. 8 is a view showing the structure of another embodiment of the line-of-sight guide support device 1.

  The line-of-sight guidance mark support device 1D has a gap U # 3 having a gap U # 3 larger than the gap U # 1 of the clamping part 111 at the lower part of the clamping part 111 which is two plate-like parts facing each other in the guidance mark support part 11. The unit 113 is provided. As shown in FIG. 8, the gap 113 is formed with a round cross section. Note that definitions of other shapes and dimensions (not shown) are the same as those in FIG. 3B, and thus description thereof is omitted here.

  The gaze guidance mark support apparatus 1D shown in FIG. 8 can further easily expand the U-shaped portion by the gap portion 113 as compared with the gaze guidance mark support equipment 1 of the embodiment shown in FIG. Thereby, the gaze guidance mark 2 having a thicker plate thickness than that of the gaze guidance mark support equipment 1 of the embodiment shown in FIG. 3 can be sandwiched. For example, when a reflective material such as the reflective sheet 22 shown in FIG. 4 with a different thickness is used, a thicker reflective material or the like can be used.

(Example 6)
FIGS. 9 and 10 are views showing an example in which the line-of-sight guide support device 1 is installed on the adherend structure 5. In particular, FIG. 9A shows an installation example in which the line-of-sight guide support device 1 is attached to the column 51 supporting the guard pipe 52, and FIG. 9B shows the line-of-sight guide mark on the column 53 of the guard rail 54. The example of installation which stuck supporter material 1 is shown. FIG. 10 (A) shows an installation example in which the gaze guidance mark support device 1 is attached to the column supporting the protective fence 55, and FIG. 10 (B) shows the gaze guidance mark support on the wall of the concrete column 56. The example of installation which stuck the equipment 1 is shown. The length of the line-of-sight guide support device 1 is different in the examples shown in FIGS.

  As shown in FIG. 9 (A), the line-of-sight guide support device 1 to which the line-of-sight guide 2 is attached can correspond to an installation form in which it is attached to a column 51 between two guard pipes 52. Note that the shape and size of the line-of-sight guide 2 are such that the line-of-sight guide 2 does not become a problem of visibility, such as being hidden by the column 51 or the guard pipe 52 when viewed from the driver of the vehicle. The same applies to the other examples shown in FIGS.

  Further, as shown in FIG. 9B, it is possible to cope with an installation form in which the visual guidance indicator support device 1 to which the visual guidance indicator 2 is attached is attached to a column 53 that supports the guard rail 54.

  Similarly, as shown in FIG. 10 (A), the gaze guidance mark support device 1 to which the gaze guidance mark 2 is affixed can be applied to an installation form in which the gaze guidance mark support device 1 is affixed to the support fence 55 column.

  In the installation form of the wall surface 561 of the concrete rail 56 shown in FIG. 10 (B), the attachment surface of the structure mounting portion 12 in the line-of-sight guide support material 1 is a plane, but as described above, the line-of-sight guide support device 1 Therefore, the bottom surface along the arc shape of the structure mounting portion 12 can be flexibly bent by an appropriate pressing force, and can be adhered and adhered to the wall surface 561 of the concrete balustrade 56. In addition, it is durable against peeling force even after sticking.

  As described above, the line-of-sight guide support device 1 can be widely used regardless of the diameter of the column 51 of the guard pipe 52, the column 53 of the guard rail 54, the column of the protective fence 55, etc. Moreover, it can respond also to the wall surface 561 etc. of the concrete balustrade 56 where a sticking surface is near a plane.

(Example 7)
FIG. 11 is a diagram illustrating another example in which the line-of-sight guidance mark support device 1 is installed, and FIG. 12 is a diagram illustrating another example in which the line-of-sight guidance mark support device 1 is installed.

  FIG. 11 shows a main road for a vehicle traveling in the direction X # 4 and a junction where a ramp road for a vehicle traveling from the direction X # 3 that merges with the main road meets. A situation in which a group 57 of a plurality of lane markings 571 in the vicinity of the point is installed.

  The lane marking 571 alerts the driver of the vehicle traveling on the main road and the driver of the vehicle traveling on the ramp side road to prevent erroneous entry and to travel in the reverse direction (reverse running). It is a cylindrical sign used for the purpose. As shown in FIG. 11, the plurality of lane separators 571 are installed at a predetermined interval near the boundary between the main road and the ramp road so as to form a group 57.

  Such lane markings 571 are provided, for example, at existing locations throughout the country as existing equipment, and are often employed even when newly established. For example, in the existing lane marking 571, a pole diameter of about Φ = 80 mm is generally used. In order to improve the line-of-sight guidance performance, a conventional method of winding a reflective sheet around a cylindrical pipe, A painted method that includes beads is used. In addition, there is a method of using a new cylindrical cap on the old main body for the lane marking 571 whose reflection performance is remarkably deteriorated due to dirt or aging.

  In such a lane separation marker 571, the sight guidance marker support device 1 can be used for the existing lane separation marker 571 in order to improve the line-of-sight guidance performance of the existing lane separation marker 571. In other words, a reflector that makes it easy for the driver to recognize the vehicle approach direction and that has high line-of-sight guidance performance is adopted, and this is attached to the line-of-sight guide support device 1 (1H) as the line-of-sight guidance mark 2 (2H). It can be attached to the separation mark 571.

  A specific example thereof will be described below with reference to FIG. In FIG. 12, in particular, FIG. 12A shows a gaze guidance mark set 10H installed on an existing lane separation gage 571, and FIG. 12B shows a gaze guidance of a plurality of installed gaze guidance mark sets 10H. It is a figure explaining an effect.

  The line-of-sight guidance mark set 10H includes a line-of-sight guidance mark support device 1H and a line-of-sight guidance mark 2H. The line-of-sight guidance mark set 10H is obtained by attaching the line-of-sight guidance mark 2H to the line-of-sight guidance mark support equipment 1H as described above. As shown in FIG. 571 is installed.

For example, in order to make a driver of a vehicle traveling on a ramp-side road more strongly recognize the traveling direction X # 3, as shown in FIG. 12A, the line-of-sight guidance installed in a group 57 of lane separators 571 The mark set 10H is visually recognized as an arrow (such as a chevron). Specifically, as shown in FIG. 12B, the arrow layout is divided into a plurality of visual guidance indicators 2H, and each of them is attached to the visual guidance indicator support device 1H to form a visual guidance indicator set 10H. .
As shown in FIG. 12A, the line-of-sight guide mark set 10H is attached to each lane separation mark 571 with the angle with respect to the direction X # 3 adjusted.

  In addition, in the junction part of an automobile exclusive road as shown in FIG. 11, a vehicle that flows into the main road (direction X # 4) from the ramp side road (direction X # 4) is accidentally turned (U-turn) at the time of merging. In order to prevent accidents caused by reverse running, a lane marking 571 is installed. In this case, it is effective to clearly indicate the approach direction to the main road with a chevron or the like as shown in FIG. 12A for a vehicle entering the main road from the ramp side. Conversely, if this is visible from the main road, the driver may be confused. For this reason, it is desirable to set the angle of the line-of-sight guidance mark set 10H where chevron or the like is difficult to visually recognize from the main line side.

  According to the gaze guidance mark support apparatus 1 (1H) of the present invention, it can be adapted to the length of the gaze guidance mark 2H. Further, as described above, it can be affixed to the clamping part 111 of the guide mark support part 11 so that it can be clamped with sufficient strength. It can be bent to the curved surface of the separation mark 571 and firmly attached to the sticking surface. Even after the installation, the uneven structure of the line-of-sight guide support material 1 can disperse stresses such as shearing force and peeling force acting on the structure mounting portion 12.

  As described above, the line-of-sight guide support device 1 (1H) can be easily attached to the column such as the lane separation mark 571 in order to attach the line-of-sight guide mark 2H for enhancing the line-of-sight guide function effect. . As a result, the line-of-sight guidance mark set 10H using the line-of-sight guidance mark support equipment 1 (1H) can be easily installed on the existing and new lane markings 571 and the like, so that the construction cost can be reduced.

  In addition, since the existing lane separator 571 can be replaced with new equipment having a new line-of-sight guide sign function, no construction work related to the installation of new equipment is required. The installation cost can be reduced because it can be installed easily.

  Further, in the case of a vehicle collision / stepping, etc., as described above, the visual guidance indicator support equipment 1H receives an external force, so that damage or the like can be avoided and maintenance costs can be reduced.

  FIG. 11 shows an example in which the line-of-sight guide set 10H is installed on the lane separator 571 with respect to the traveling direction X # 3 of the ramp side road. May be installed. Further, the target on which the line-of-sight guidance mark support equipment 1 is installed is not limited to the lane separation mark 571, and may be a spot-type line-of-sight guidance mark, a snow pole, or the like.

  These line-of-sight guide support materials 1 described in the above example can be manufactured from a few types of extruded molded products by simple processing such as cutting and fusing to a corresponding length. As a result, the producers can reduce the number of types of equipment, thereby reducing production costs, inventory costs, and the like. In addition, since there are few types of equipment for installers, maintenance personnel, etc., installation can be performed with simple operations, construction costs, maintenance costs, and the like can be reduced.

  From the viewpoint of landscape, it is space-saving and can be installed so as not to stand out from the side of pedestrians, etc., which is effective when considering landscape.
