Description

  The present invention relates to an additional member that is attached to a pile and adds a further function to an existing pile.

  Pile is used for displaying survey points, boundaries, etc., but it is also used for various purposes by taking advantage of easy installation. Recently, IC tags are housed in piles and not only the piles and their peripheral information are managed by the IC tags, but also sensors are housed to function as information transmission piles (Patent Document 1).

Patent No. 4299355

  However, in the pile described in Patent Document 1, the IC tag and the sensor are stored inside the pile. Therefore, when exchanging or adding these IC tags and sensors, it is necessary to work by removing the caps placed on the heads of the piles. Therefore, when there are a large number of piles to be worked, a long time is required for the work.

  Then, it aims at providing the extension member which adds a functional further to an existing pile easily by adding functional parts including an IC tag, a sensor, etc. to a pile easily.

  In order to achieve the above object, an additional member according to one configuration of the present invention is an additional member that is attached to a pile and adds a further function to the pile, and has a cylindrical elasticity having three or more side walls. A main body formed from a body, comprising a main body having a first flat plate portion and a second flat plate portion respectively included in two of the three side walls, and the first flat plate portion includes: A mounted portion to be mounted on the pile is configured, and a first functional component mounting portion to which a first functional component that adds a further function to the pile is mounted is configured on the second flat plate portion.

  According to this configuration, since the first functional component can be attached to the main body of the additional member, any function can be added to the existing pile by the first functional component. Moreover, since the main body of the additional member is formed from the elastic body, an impact can be absorbed. In particular, since a space is formed by three or more side walls, the side walls are easily bent when receiving an external force from a direction perpendicular to the axial direction of the cylindrical main body, and effectively absorb the impact. Can do. Furthermore, since the main body of the extension member is cylindrical, the area of the cylindrical main body that receives external force from the axial direction is smaller than when the main body is solid. For example, when a water flow or wind is received from the axial direction of the cylindrical main body, water or wind passes through the space inside the side wall, so that it is not easily affected by water pressure or wind pressure.

Preferably, the main body has a triangular tube shape having three side walls.
Preferably, the elastic body is a rubber body made of synthetic rubber or natural rubber.

  In preferable embodiment of this invention, it is a fixing tool provided in the said to-be-attached part, Comprising: The fixing tool which fixes and attaches the said additional member to the said pile is provided. According to this embodiment, since the fixture for fixing and mounting the additional member on the pile is provided in the mounted portion, the additional member can be easily mounted on the existing pile by this fixture.

  Preferably, the fixture is a nail, a hook or a screw. Since the fixing tool is a nail, a hook, or a screw, the extension member can be easily attached to an existing pile while having a simple configuration.

  Preferably, the fixture is a magnet. Since the fixture is a magnet, the extension member can be attached to and removed from the existing pile very easily as long as the pile contains the metal to which the magnet is adsorbed.

  In another preferred embodiment of the present invention, the mounted portion is provided with an opening that is slightly smaller than the cross-sectional dimension of the head of the pile, and the additional member has the head of the pile inserted into the opening. Attached to the pile. According to this embodiment, the opening is inserted into the head of the pile, and the opening for fixing and mounting the additional member on the pile is provided in the mounted portion. Therefore, the additional member has a simple configuration. Nevertheless, the additional member can be easily attached to an existing pile.

  In a further preferred embodiment of the present invention, the first functional component is an IC tag or a sensor. According to this embodiment, since the IC tag or the sensor is provided on the extension member, when the extension tag is attached to the existing pile, the IC tag or sensor of the existing pile breaks down. Can be used as Therefore, when replacing the IC tag or the sensor housed in the pile, the replacement work performed by removing the cap on the head of the pile is a simple work of simply mounting the additional member. In addition, even when another IC tag or sensor is added to an IC tag or sensor that is operating on an existing pile, it is necessary to remove the cap on the head of the pile and store the additional IC tag or sensor in the pile. There is no need to install additional members. Furthermore, even if the pile does not have a space for storing the IC tag and the sensor, the IC tag and the sensor can be provided on the pile by attaching the additional member to the pile, so that it is particularly effective.

Here, the “IC tag” refers to a non-contact type IC tag (RFID tag), and performs wireless communication using RFID technology via a communication antenna. An “active IC tag” means an active type, that is, an IC tag that transmits a radio wave by providing a battery, whereas a “passive type IC tag” is a passive type, that is, a reader, for example. It means a device that receives radio waves from the above and operates using the power supplied in this way.
The “sensor” includes an acceleration sensor, a temperature sensor, an impact sensor, a gas sensor, and the like, and may be any sensor as long as it can be provided on the additional member.

  In a further preferred embodiment of the present invention, the first functional component is a reflective sheet, and the first functional component mounting portion is configured on the outer surface of the second flat plate portion. According to this embodiment, since the reflection sheet is provided on the extension member, the visibility when light is irradiated can be improved by mounting the extension member on the existing pile. Preferably, the 2nd flat plate part which has the outer surface in which a reflective sheet is provided inclines in the state where it was equipped to the pile. Thereby, for example, when light is irradiated from the front in the horizontal direction toward the outer surface, the light is reflected from the outer surface, so that the pile can be easily seen from the front.

  In a further preferred embodiment of the present invention, the main body further has a third flat plate portion, and a second functional component for adding a further function to the pile is attached to the third flat plate portion. The functional component mounting portion is configured. According to this embodiment, since the second functional component attachment portion to which the second functional component is attached is configured on the third flat plate portion of the main body, the second functional component can be attached to the attachment portion. With the functional component, in addition to the function by the first functional component, an arbitrary function can be added to the existing pile. The second functional component may be the same type or different type from the first functional component.

  In a further preferred embodiment of the present invention, the second functional component is an IC tag or a sensor.

  According to the expansion member of the present invention, when an external force is applied from a direction perpendicular to the axial direction of the cylindrical main body, the side wall can be bent into the space, so that an impact can be effectively absorbed. Since the area of the main body that receives external force from the axial direction is smaller than the case where the main body is made of a solid body, it can be used by being mounted on a pile installed in a harsh environment. That is, for example, even if piles are installed in places that are highly likely to be stepped on by humans or automobiles, or places that receive high-speed water currents or winds, they are attached to the heads of the piles and located on the ground. The possibility that the additional member is damaged under these influences is extremely low.

Hereinafter, an additional member according to the first embodiment of the present invention will be described with reference to the drawings.
1 (a) and 1 (b) show the additional member 1 and the pile 80, FIG. 1 (a) shows a state before the additional member 1 is mounted on the pile 80, and FIG. Shows a state after the additional member 1 is mounted.

  The stake 80 is an installation position information indicator that displays installation position information (for example, positions such as land and road (positions based on longitude, latitude, and altitude) or various information about the site) that are information related to the installation position.

  The stake 80 is a stake that is driven almost vertically into the ground, and has a stake main body 82, and the head 84 is covered with a protective cap 86. The pile body 82 and the cap 86 are made of plastic, for example, but may be made of concrete, and may be made of metal as long as the communication function is not hindered. The pile 1 has a storage space 88 inside, and an upper portion thereof is opened and covered with a cap 86.

  The storage space 88 of the pile 80 includes an IC tag (pile storage IC tag) 92 stored in the pile, a sensor (pile storage sensor) 94 stored in the pile, and a communication antenna (for pile storage communication) stored in the pile. An antenna) 96, a power source 98, and the like are accommodated. The pile storage IC tag 92 is a non-contact IC tag (RFID tag), and performs wireless communication using the RFID technology via the communication antenna 96. The pile storage IC tag 92 may be an active type or a passive type, and is preferably an active type. When the pile storage IC tag 92 is an active type, the power source 98 is used not only for the operation of the pile storage sensor 94 but also for the operation of the pile storage IC tag 92.

  The pile storage sensor 94 is an acceleration sensor, for example, and detects that the pile 80 has received an impact. In addition, the pile storage sensor 94 may be a temperature sensor, a vibration sensor, a gas sensor, or the like. Moreover, the pile storage sensor 94 is not limited to one, and a plurality of pile storage sensors 94 may be provided. If a plurality of types of sensors are provided, a plurality of objects can be detected.

  The information detected by the pile storage sensor 94 is stored in a storage area (not shown) of the pile storage IC tag 92 and transmitted via the pile storage communication antenna 96. The detection information transmitted in this way is managed by a management server (not shown) and is used to detect a change in the vicinity of the place where the pile 80 is installed (for example, occurrence of an abnormality such as the occurrence of vibration). The

  A solar panel (not shown) may be attached to the four side surfaces of the pile 80. The solar panel and storage battery (not shown) can assist the power source 98. Moreover, you may make it produce | generate required electric power only by the electric power generation by a solar panel, without providing the power supply 98. FIG.

  With reference to Fig.2 (a)-(d), the expansion member concerning 1st Embodiment is explained in full detail. The additional member 1 includes a main body 10. The main body 10 is formed of a triangular cylindrical elastic body, and three flat plate portions 12 (a first flat plate portion 12a, a second flat plate portion 12b, and a third flat plate portion 12c) constitute side walls. The three flat plate portions 12 may be formed integrally, or may be formed separately and joined by adhesion or the like. Thus, since the main body 10 has a triangular cylindrical shape, a space S surrounded by the three flat plate portions 12 is formed. Since the main body 10 has a hollow shape in which the space S is formed, it has excellent shock absorption and is not easily destroyed. Moreover, the main body 10 is lighter than the case where it is solid. Furthermore, since the main body 10 has a cylindrical shape, it is easy for an operator to put a hand into the opening at both ends and carry it.

  The main body 10 is formed from an elastic body. In the present embodiment, the elastic body is a rubber body. As rubber, natural rubber, ethylene propylene rubber (EPDM), chloroprene rubber (CR), butadiene rubber (BR), silicone rubber (Si), nitrile rubber (NBR, NBR + PVC (polyvinyl chloride (PVC) blend) ) And other synthetic rubbers. Synthetic rubber is selected according to the application. For example, those having weather resistance such as ethylene propylene rubber, chloroprene rubber, and silicone rubber are suitable for outdoor use. Moreover, when oil resistance is required, chloroprene rubber and nitrile rubber are suitable. The desirable range of rubber hardness of the body 10 depends on environmental conditions.

  The rubber body of the main body 10 may preferably have a fiber reinforcement layer (not shown) made of thread or cloth between the rubber layers. Thereby, the rigidity of the support body 10 is improved and is not easily destroyed. Moreover, even if it is destroyed, the crack stops at the fiber reinforcing layer, so that the crack is prevented from becoming large. In addition, such a fiber reinforcement layer is employ | adopted according to the environmental condition which uses the expansion member 1. FIG.

  Of the three flat plate portions 12, an outer surface 12aa of the first flat plate portion 12a is configured with a mounted portion 12ab to be mounted on the pile 80 (FIG. 1A). That is, as shown in FIG. 1A, the outer surface 12aa of the first flat plate portion 12 a is a portion that comes into contact with the upper surface of the cap 86 of the pile 80. In the additional member 1 according to the first embodiment, a fixture 20 made of a nail is provided on the mounted portion 12ab shown in FIG. Even if the nail 20 protrudes from the outer surface 12aa of the first flat plate portion 12a through the hole 12ac provided near the center of the first flat plate portion 12a, the nail 20 is bonded to the outer surface 12aa of the first flat plate portion 12a. It may be what was done. When the nail 20 is driven into the cap 86 (FIG. 1A) of the pile 80 (FIG. 1A), the additional member 1 is attached to the pile 80. A screw (not shown) may be used as a fixture instead of the nail 20.

  Furthermore, as shown in FIG. 3, a metal cage 20 may be used as a fixture.

  The second flat plate portion 12b intersects the first flat plate portion 12a at an acute angle, the third flat plate portion 12c intersects at a substantially right angle, and the second flat plate portion 12b and the third flat plate portion 12c have an acute angle. Cross at. For this reason, the triangular cylinder shape of the support 10 is a substantially right triangle cylinder shape. In the circumferential direction of the cylindrical shape, the length L1 of the first flat plate portion 12a is preferably 0.5 to 1.7 times the length L3 of the third flat plate portion 12c. In addition, the axial length LL of the cylindrical support 10 is shorter than the length L1 of the first flat plate portion 12a, preferably 0.5 to 1 to the length L1 of the first flat plate portion 12a. 0.8 times.

  Of the three flat plate portions 12, the second flat plate portion 12b is attached with a first functional component (here, an additional IC tag body 30) that adds a further function to the pile 80 (FIG. 1A). It is a part that is The second flat plate portion 12b has an outer surface 12ba, and a first functional component attachment portion 12bb for attaching the additional IC tag body 30 to the outer surface 12ba is configured. The additional IC tag body 30 has a flat plate shape, and preferably has a disk shape. A through hole 32 is formed at the center of the additional IC tag body 30. On the other hand, a through hole 12bc is also formed in the second flat plate portion 12b. The additional IC tag body 30 is fixed to the additional member 1 first by positioning the additional IC tag body 30 so that the through hole 32 of the additional IC tag body 30 matches the through hole 12bc of the second flat plate portion 12b, and these through holes 32, 12bc. And the screw 42 is screwed into the nut 44 positioned on the inner surface 12bd side of the second flat plate portion 12b.

  Since a space S is formed between the first functional component mounting portion 12bb to which the additional IC tag body 30 is mounted and the nail 20, a certain distance is secured between the additional IC tag body 30 and the nail 20. Is done. Therefore, even when the nail 20 is made of metal, the possibility that the nail 20 adversely affects the radio waves communicated between the IC tag of the additional IC tag body 30 and the reader / writer can be suppressed.

  Next, the additional IC tag body 30 attached to the first functional component attachment portion 12bb will be described with reference to FIGS. 4 (a) and 4 (b). The additional IC tag body 30 includes an additional IC tag 36 including an IC chip 33 and an additional antenna 34 including a coil, and a housing 38 that accommodates the additional IC tag 36 therein.

  Since the additional IC tag 36 is a non-contact type as described above, the additional IC tag 36 has an additional antenna 34 and performs wireless communication using RFID technology. Preferably, the additional IC tag 36 is a passive type. Tag information is read from and written into the additional IC tag 36 by a reader / writer (not shown). As an example of a reader / writer, there is one installed in a smartphone (multifunctional mobile phone).

  The housing 38 has a disk shape and includes a base portion 42 and a cover 44. The base part 42 has an annular recess 42c between the peripheral part 42a and the center part 42b. The IC chip 33 and the additional antenna 34 of the additional IC tag 36 are disposed in the recess 42c, and the additional antenna 34 is wound around the central portion 42b along the ring shape of the recess 42c. The disc-shaped cover 44 is supported by the peripheral edge portion 42a and the central portion 42b of the base portion 42 and covers the space 46 constituted by the concave portion 42c.

  Holes 48 and 49 are formed at the centers of the base 42 and the cover 44 of the housing 38, respectively. These holes 48 and 49 constitute the above-described through-hole 32 (FIG. 2D) and are used for screwing the attachment to the main body 1 (FIG. 2D).

  The base portion 42 and the cover 44 of the housing 38 are made of plastic, preferably siloxane copolymer polycarbonate. This siloxane copolymerized polycarbonate has a structure in which polydimethylsiloxane (PDMS) is copolymerized with a molecular chain of polycarbonate (PC) by chemical bonding. Thus, since the exterior of the additional IC tag body 30 is composed of a siloxane copolymer polycarbonate, it is excellent in heat resistance, weather resistance, alkali resistance, acid resistance, impact resistance, cold resistance and flame resistance. In particular, a siloxane copolymer polycarbonate having superior weather resistance, impact resistance, and cold resistance compared to polycarbonate is used for the exterior of the additional IC tag body 30.

  When the casing 38 is made of a siloxane copolymer polycarbonate, the same transparency as that of the polycarbonate can be ensured. Therefore, one or both of the base portion 42 and the cover 44 may be made transparent or semi-transparent so as to be visible from the outside. Since the casing 38 made of siloxane copolymer polycarbonate is more elastic than that made of polycarbonate, it is possible to prevent a gap from being formed between the base portion 42 and the cover 44 that is covered with the base portion 42 by adhesion or the like. The space 46 is excellent in sealing performance.

  The outer surface 44a of the cover 44 of the housing 38 may be designed or a reflective sheet may be attached.

  Since the main body 10 of the additional member 1 shown in FIGS. 2A to 2D is formed of a rubber body, the additional IC tag 36 (FIG. 4B) of the additional IC tag body 30 and the reader / writer The main body 10 itself does not impede obstructions such as shielding and reflection to radio waves communicated between them. In addition, since the rigidity of rubber is small in temperature dependence, it does not cause shape deformation when it exceeds a certain temperature unlike a resin. Furthermore, since rubber is more excellent in resilience than resin, the main body 10 formed from a rubber body is restored to its original shape even if it is stepped on. Since the space S is formed inside the main body 10, the additional member 1 receives an external force from the direction R perpendicular to the axial direction X of the main body 10 (for example, the second flat plate portion 12b is pressed from the outside). ) And the second flat plate portion 12b and the third flat plate portion 12c of the rubber body are greatly bent and then restored to their original shapes. Therefore, an impact can be effectively absorbed. In addition, since rubber has better bending resistance than resin, the main body 10 formed from a rubber body is less likely to crack even if it is repeatedly deformed.

  In the present embodiment, the additional IC tag body 30 is attached to the outer surface 12ba of the second flat plate portion 12b of the main body 10, but the additional IC tag body 30 is attached to the inner surface 12bd of the second flat plate portion 12b. Also good. In this configuration, even if the main body 10 is stepped on, the additional IC tag body 30 can be prevented from being stepped on directly. In this case, a heat reflecting paint may be applied to the outer surface 12ba of the second flat plate portion 12b. Thereby, the temperature rise of the additional IC tag body 30 provided on the inner surface 12bd is prevented.

  Note that the first functional component such as the additional IC tag body 30 may be provided on both the outer surface 12ba and the inner surface 12bd of the second flat plate portion. In this case, the two first functional components may be the same type or different types.

Next, application of the additional member according to the first embodiment will be described.
Returning to FIG. 1A, it is assumed that the pile 80 is partially embedded in the ground. The “operation” of the pile provided with the pile storage sensor 94 as in this embodiment is not only functioning as the pile 80 indicating the installation position information, but also the pile storage sensor 94 (if it is an acceleration sensor). For example, the object is detected and stored), and the detection information is managed, for example, the detection information is transmitted via the pile storage communication antenna 96, and the management server (not shown) or the like It means being managed. The extension member 1 is mounted on the pile 80 operating in this way.

  When the additional member 1 is mounted on the pile 80, the second flat plate portion 12b to which the additional IC tag body 30 is attached forms an inclined surface with respect to the road surface in which the pile 1 is embedded. For this reason, the additional IC tag body 30 is provided on the inclined surface, and the visibility is higher than when the additional IC tag body 30 is provided on the horizontal plane. Further, when the additional IC tag body 30 is provided on the slope, it is easier to hold a reader / writer such as a smartphone than when the additional IC tag body 30 is provided on a horizontal plane or a vertical plane. Furthermore, in this embodiment, since the dimension of the horizontal section of the additional member 1 is larger than the dimension of the horizontal section of the pile 80, the dimension of the slope of the second flat plate portion 12b is also larger than the pile 80. As a result, the visibility of the additional IC tag body 30 is further enhanced and the reader / writer is more easily held over.

  In addition to the information stored in the pile storage IC tag 92, the additional IC tag body 30 of the additional member 1 mounted in this manner can store further management information. For example, while the pile storage IC tag 92 is used for storing and transmitting the detection information of the pile storage sensor 94, the additional IC tag body 30 is managed separately from the pile 80 (for example, the pile 80 Can be used for the management of underground buried objects in the vicinity of

  As an alternative, when the pile storage IC tag 92 breaks down, the additional IC tag body 30 can be used as a substitute for the broken IC tag by mounting the additional member 1 on the pile 80. In this case, if the additional member 1 is attached to the pile 80 while storing the existing pile storage IC tag 92 and the pile storage sensor 94 as they are, the cap 86 of the pile 80 is removed and the parts in the storage space 88 are replaced. There is no need to replenish. However, when wiring is necessary for a component such as the power source 98 in the storage space 88, the cap 86 of the pile 80 is removed as necessary for connection.

  The additional member 1 according to the present embodiment is applied to, for example, a pile 80 embedded in a large number of underground water channels for hydroelectric power generation. In an environment where the work is difficult in this way, the cap 86 of the underwater pile 80 is removed, and it is only necessary to mount the additional member 1 without performing the work. Further, after the expansion member 1 is mounted, the main body 10 shown in FIG. 2A is not a solid body but a cylindrical body, so that the water in the underground water channel passes through the space S inside the main body 10 and is expanded. The member 1 and the pile 80 (FIG. 1A) to which the member 1 is attached are not easily affected by water pressure. Furthermore, if the inclination direction of the outer surface 12bb of the 2nd flat plate part 12b which comprises an inclined surface is made the same about many piles, many piles will be maintained for the maintenance of the pile 80 (FIG. 1 (a)). When checking sequentially, it is easy to check.

  In addition to this, the additional member 1 according to the present embodiment may be applied to, for example, a pile 80 installed on the side of the expressway along the highway. If the additional member 1 is mounted on the pile 80 so that the second flat plate portion 12b (FIG. 2A) constituting the inclined surface can be seen from the traveling vehicle in accordance with the traveling direction of the expressway, the work efficiency is improved. .

  In the present embodiment, as a first functional component, an additional sensor (not shown) is attached to the first functional component mounting portion 12bb of the second flat plate portion 12b of the expansion member 1 instead of the additional IC tag body 30. Also good. The additional sensor may be the same type as or different from the pile storage sensor 94 in FIG. For example, while the pile storage sensor 94 is an acceleration sensor, the additional sensor is a temperature sensor, and in addition to the acceleration generated in the pile 80, a function for detecting the temperature in the pile 80 can be added by the additional member 1. May be.

  In this embodiment, the pile storage sensor 94 may be omitted. That is, the sensor function may be added to the pile 80 by attaching the additional member 1 to the pile 80 that does not store the sensor.

  In this embodiment, the additional member 1 does not necessarily have to be mounted with the pile 80 embedded in the ground. That is, after the extension member is fixed to the pile 80 with the nail 20 of the extension member 1, it may be embedded in the ground.

  Next, an additional member according to the second embodiment of the present invention will be described with reference to FIGS. The difference between the expansion member 1 according to the present embodiment and the expansion member according to the first embodiment is that the fixture is made of a magnet. About the other point, the structure of the additional member concerning 1st Embodiment mentioned above is applied. The same components are denoted by the same reference numerals, and description thereof is omitted.

  The mounted portion 12ab formed on the outer surface 12aa of the first flat plate portion 12a of the additional member 1 according to the present embodiment is provided with a fixture 20A made of a magnet (adsorption magnet). The magnet 20A is a permanent magnet. However, the pile 80 (FIG. 1A) on which the additional member 1 according to the present embodiment is mounted is an adsorbed body including a metal to which the magnet 20 </ b> A is adsorbed. In this way, the magnet 20A is fixed to the main body 10, and the extension member 1 is attached to the extension member 1 only by the adsorption of the magnet 20A. The number of magnets 20A is preferably one, but may be plural.

  In the present embodiment, the magnet 20A is fixed to the main body 10, but the magnet 20 may be integrally formed with the main body 10. Further, a combination of a fixing tool 20 (FIG. 2 (d)) made of a nail or a screw provided on the additional member 1 according to the first embodiment and the magnet 20A is used to not only attract the magnet 20A but also a nail, a screw or a hook. The extension member 1 may be used for mounting.

  Next, an additional member according to the third embodiment of the present invention will be described with reference to FIGS. The expansion member according to the present embodiment is different from the expansion member according to the first and second embodiments in that the head of the pile is pushed into the mounting opening formed on the mounting portion of the expansion member instead of the fixture. The additional member is attached to the pile. About the other point, the structure of the expansion member concerning 1st and 2nd embodiment mentioned above is applied. The same components are denoted by the same reference numerals, and description thereof is omitted. In addition, illustration of a 1st functional component is abbreviate | omitted in FIG. 6 (a) and (b).

  As shown in FIG. 6A, a mounting opening 12ad is formed in the mounted portion 12ab of the first flat plate portion 12a of the additional member 1 according to the present embodiment. The mounting opening 12ad has the same shape as the cross-sectional shape (square in the present embodiment) of the head of the pile 80 to which the main body 1 of the additional member 1 is mounted. It is slightly smaller than the cross-sectional dimension of the head 86.

  As shown in FIG. 6B, the mounting of the additional member 1 to the pile 80 is performed by fitting the head 86 of the pile 80 into the mounting opening 12 ad of the additional member 1. Then, since the mounting opening 12ad is slightly smaller than the cross-sectional dimension of the head portion 86 of the pile 80 after being fitted, the additional member 1 is fixed to the pile 80 as shown in FIG.

  According to the present embodiment, the additional member 1 can be easily mounted on the existing pile 80 while having a simple configuration in which the mounting opening is formed without separately providing a fixture.

  Next, an additional member according to the fourth embodiment of the present invention will be described with reference to FIGS. 7 (a) and (b). The difference between the expansion member according to the present embodiment and the expansion member according to the first to third embodiments is that a second functional component is further provided. About the other point, the structure of the expansion member concerning the 1st-3rd embodiment mentioned above is applied. The same components are denoted by the same reference numerals, and description thereof is omitted.

  The third flat plate portion 12c of the additional member 1 according to the present embodiment has an outer surface 12ca, and a second functional component for attaching a second functional component (here, referred to as an additional sensor 35) to the outer surface 12ca. A mounting portion 12cb is configured. The additional sensor 35 is a temperature sensor, for example. The detection information of the temperature sensor 35 is stored in the additional IC tag 36 (FIG. 4B) of the additional tag body 30 that is the first functional component via a cable (not shown).

  Next, an additional member according to the fifth embodiment of the present invention will be described with reference to FIGS. 8 (a) and 8 (b) and FIG. The difference between the expansion member according to the present embodiment and the expansion member according to the first to fourth embodiments is the shape of the expansion member. About the other point, the structure of the expansion member concerning the 1st-4th embodiment mentioned above is applied. The same components are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 8A, the main body 10 of the additional member 1 according to the present embodiment is not the cylindrical shape of the right triangle shown in the first to fourth embodiments, but the first flat plate portion 12a as the bottom surface. It is made of an isosceles triangular cylinder. With this shape, when mounted on the pile 80, as shown in FIG. 8B, two inclined surfaces are formed by the outer surfaces 12ba and 12ca of the second and third flat plate portions 12b and 12c. Thus, when two inclined surfaces are comprised, these inclined surfaces can be visually recognized from two directions opposite to each other. Therefore, the configuration of this embodiment is particularly effective when the designs D1 and D2 are applied to the outer surfaces 12ba and 12ca of the flat plate portions 12b and 12c shown in FIG.

  In addition, the shape of the main body 10 of the additional member 1 according to the present embodiment is not limited to an isosceles triangular cylindrical shape, and the second and third flat plate portions 12 and 12c are inclined when mounted on the pile 80. Any triangle may be used as long as it is arranged.

  Next, an additional member according to the sixth embodiment of the present invention will be described with reference to FIGS. 10 (a) and 10 (b). The difference between the expansion member according to the present embodiment and the expansion member according to the fifth embodiment is that a reflection sheet is provided as the first and second functional components. About the other point, the structure of the expansion member concerning 5th Embodiment mentioned above is applied. The same components are denoted by the same reference numerals, and description thereof is omitted.

  The first functional component mounting portion 12bb and the third flat plate portion 12c of the second flat plate portion 12b of the cylindrical main body 10 made of an isosceles triangle of the additional member 1 according to the present embodiment and the second functional component mounting portion. Each of 12cb is provided with a reflective sheet 30A. Since the reflection sheets 30A are provided on the outer surfaces 12ba and 12ca constituting the two inclined surfaces as described above, when the additional member 1 is mounted on the pile 80 (FIG. 8A), light is transmitted to these outer surfaces 12ba. , 12ca can be improved in visibility. For example, when the additional member 1 is mounted on the pile 80 (FIG. 8A) installed on the road, the headlight of the traveling vehicle irradiates the inclined surface 12ba (or 12ca) from the front in the horizontal direction. The reflection sheet 30A reflects the irradiation light in the horizontal direction, and can inform the driver of the automobile that the pile 80 is installed. Since the reflection sheet 30A is thus provided on the two outer surfaces 12ba and 12ca having different inclination directions, the pile can be viewed from two different directions.

  In each embodiment, the case where the additional member 1 has a triangular cylindrical shape has been described, but it may have any cylindrical shape as long as it has a polygonal cross section. However, a triangular cylindrical shape is preferable.

  In addition, the first functional component and the second functional component may be any functional component other than those described above. For example, a solar panel may be used, and when the outer surfaces 12ba and 12ca of the second and third flat plate portions 12b and 12c are inclined as shown in FIG. It is possible to efficiently generate power by attaching a solar panel. The electric power generated efficiently in this way is not only consumed by the pile 80 (FIG. 1A), but also via a power cable (not shown) to a storage battery (not shown) housed in the pile 80. May be transmitted to a storage battery of another pile connected.

  If the extension member concerning 1st-6th embodiment has only the pile already installed, various uses can be added to such a pile. Examples of such applications include managing the passage of vehicles at stations or bus terminals, managing inpatients and residents in hospitals, nursing homes or prisons, managing entry and exit at nurseries, schools or companies, and managing evacuation routes. Or there is tourist information.

  As described above, according to the additional members according to the first to sixth embodiments, when an external force is received from a direction perpendicular to the axial direction of the cylindrical main body, the side wall is bent into the space, so that the impact is effectively prevented. On the other hand, the area of the cylindrical body that receives external force from the axial direction is small compared to the case where the body is made of solid material, so it must be attached to a pile installed in a harsh environment. Can do. That is, for example, even if piles are installed in places that are highly likely to be stepped on by humans or automobiles, or places that receive high-speed water currents or winds, they are attached to the heads of the piles and located on the ground. The possibility that the additional member is damaged under these influences is extremely low.
