Description

  The present invention relates to a structure in which a plurality of IC tags are embedded.

  As a structure in which a plurality of IC tags are embedded, it is known that the structure is embedded directly in the ground of a sidewalk such as a pedestrian path, for example, for a navigation system for visually impaired persons (for example, Patent Document 1).

Special table 2008-518314

If the IC tag is directly embedded as in the conventional sidewalk, for example, if the IC tag is damaged, the IC tag must be replaced by excavating the sidewalk. There is a problem that a great amount of labor must be spent.
Moreover, when a huge number of IC tags must be arranged at an appropriate interval from each other as in a navigation system, the work of embedding IC tags is complicated, and a great amount of labor must be spent. There is.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a structure in which a plurality of IC tags can be easily embedded and easily replaced.

  In order to achieve this object, a structure of the present invention is a structure in which a plurality of IC tags are embedded, and includes a tubular member embedded in the structure and exposed at both ends. The IC tag is connected by a connecting line to form an IC tag connecting body, inserted into the tubular member, and stored in a state where the connecting line of the IC tag connecting body can be pulled out from the both ends of the tubular member. It is a structure characterized by that.

  According to such a structure, a plurality of IC tags embedded in the structure are connected by a connecting line to form an IC tag connecting body, and both end portions are exposed to the tubular member embedded in the structure. By inserting the IC tag connector, a plurality of IC tags can be easily arranged. Also, by embedding a tubular member through which the IC tag connector is inserted in the structure portion, it is possible to easily embed a plurality of IC tags in the structure. At this time, since the IC tag is not directly embedded, it can be moved in the tubular member, and the connecting line of the IC tag connecting body is stored in a state where it can be pulled out from the exposed end of the tubular member. It is possible to take out the embedded IC tag by pulling the connecting line in a drawable state.

In addition, since the plurality of tubular members through which the IC tag coupling body is inserted are arranged along a predetermined direction and are arranged side by side in a crossing direction intersecting the predetermined direction, only the IC tags are connected in a line. Instead, it is possible to disperse and arrange them in a predetermined area.

In this structure, it is preferable that the plurality of tubular members into which the IC tag connector is inserted are arranged at equal intervals in the intersecting direction.
According to such a structure, since the plurality of tubular members through which the IC tag connector is inserted are arranged at equal intervals in the crossing direction, the plurality of IC tags are arranged at equal intervals in the crossing direction. It can be easily arranged. In addition, when controlling based on information held in the embedded IC tag, it is possible to control based on the premise that the embedded IC tags are arranged at equal intervals in the crossing direction, so that the control is easy. It is.

In this structure, the IC tag is allowed to move by a predetermined amount and is connected by the connecting line, and the connecting line is disposed on one side along the tubular member in the tubular member. A restriction member that allows movement of the IC tag connector when pulled, and restricts movement of the IC tag within the predetermined amount range and movement of the connection line when pulled to the other side. It is desirable that it is provided corresponding to the IC tag.
According to such a structure, in the tubular member, movement is permitted when the connecting line is pulled to one side along the tubular member, and the IC is within a predetermined range when pulled to the other side. Since the restriction member that restricts the movement of the tag and allows the movement of the connecting line is provided corresponding to the IC tag, the restriction member is pulled by pulling the IC tag coupling body to which the plurality of IC tags are connected to one side. It is possible to arrange each IC tag at a position regulated by a predetermined regulating member by pulling to the other side after passing through. At this time, since the IC tag is allowed to move by a predetermined amount and is connected by a connecting line, all the IC tags are positioned at a position where one IC tag is restricted by the restriction member. It is possible to prevent.

In such a structure, the predetermined amount is an amount that allows an error between an interval between the IC tags in the IC tag coupling body and an interval between the regulating members corresponding to the IC tags. Is desirable.
According to such a structure, the IC tags in the IC tag assembly are allowed to move in an amount that allows an error between the interval between the IC tags and the interval between the regulating members corresponding to each IC tag. Thus, each IC tag can be positioned by a corresponding regulating member and placed at a desired position.

In this structure, the structure is a reinforced concrete structure having reinforcing bars along the predetermined direction, and the tubular member has the reinforcing bars arranged along the predetermined direction on the surface side of the structure. It is desirable that they are arranged so that they do not overlap.
According to such a structure, the tubular member is arranged so that the reinforcing bars arranged along the predetermined direction do not overlap on the surface side of the structure, like the tubular member. Communication with the IC tag embedded in the structure can be performed from the surface side of the structure.

Such a structure, which is recessed with respect to the surface of the structure, exposes the end of the tubular member, and covers the storage part so as to be openable and closable to constitute the surface of the structure. And a lid member.
According to such a structure, since the housing part that is recessed with respect to the surface of the structure and the end of the tubular member is exposed is covered with the lid member, it is exposed in the housing part. It is possible to cover the end portion of the tubular member and the connecting line of the IC tag connector so as not to be exposed outside the accommodating portion. Further, since the lid member can be opened and closed, the IC tag can be exchanged by opening the lid member as necessary. Furthermore, since the lid member covers the accommodating portion and constitutes the surface of the structure, it is possible to constitute an integrated structure including the lid member.

A pipe 15 as a tubular member is embedded. More specifically, as shown in FIG. 2 and FIG. 3, the floor slab 10a has reinforcing bars (hereinafter referred to as vertical bars) 11 along the depth direction and spaced apart from each other in the left-right direction. Reinforcing bars (hereinafter referred to as transverse bars) extending in the left-right direction on the upper side of the upper vertical bars 11 and the lower side of the lower vertical bars 11 so that the reinforcing bars are almost perpendicular to each other. ) 12 is provided. At this time, the interval between the vertical stripes 11 and the interval between the horizontal stripes 12 are substantially equal, and the vertical stripes 11 and the horizontal stripes 12 form a substantially square lattice pattern. Since the pipe 15 used here is embedded in the floor slab 10a, the pipe 15 has rigidity capable of maintaining a hollow shape even when the weight of the concrete to be placed acts.

  FIG. 4 is a longitudinal sectional view showing a maintenance pit of the structure according to the present invention.

It arrange | positions so that the said horizontal stripe 12 may be contacted in the lower side of the horizontal stripe 12, and is fixed to the horizontal stripe 12. FIG. Further, as shown in FIG. 4, both end portions 15a and 15b of the pipe 15 project into maintenance pits 16 provided at both end portions in the depth direction of the warehouse.

  An IC tag connector 22 in which a plurality of IC tags 20 are connected by a non-metallic rope 21 as a connecting line is inserted into the pipe 15 embedded in the floor slab 10a. In the IC tag coupling body 22, each IC tag 20 is provided, for example, at an approximately equal interval with the interval between the longitudinal bars 11 of the reinforcing bar having a lattice shape, and each IC tag 20 is predetermined in the length direction of the rope 21. It is mounted so as to be movable within range. Therefore, as shown in FIG. 2, each IC tag 20 is set so as to be positioned at the center of each quadrilateral formed by the grid-like reinforcing bars 11 and 12, and the inside of each quadrilateral grid is set. The area that is a tangent circle substantially matches the communicable area between each IC tag 20 and the transmission / reception unit of the transfer robot 30.

  FIG. 5 is a longitudinal sectional view for explaining a regulating member provided in the structure according to the present invention.

  A regulating member 18 that regulates the position of the IC tag 20 protruding from the inner peripheral surface of the pipe 15 is provided inside the pipe 15. The restricting member 18 is inclined toward the center of the cross section of the pipe 15 and toward the one end portion 15 a side in the longitudinal direction of the pipe 15. In the example of FIG. 5, the regulating member 18 is inclined toward the center of the cross section of the pipe 15 and toward the right end 15 a side in the longitudinal direction of the pipe 15.

  The IC tag connector 22 inserted from the other end 15b side of the pipe 15 can be moved by pulling to the one end 15a side. The IC tag 20 that has moved from the member 18 to the one end 15a side is restricted by the restricting member 18 from moving toward the other end 15b, and the IC tag 20 is positioned. Further, in the pipe 15 of the present embodiment, when the pipe 15 is embedded, a regulating member position indicating that the regulating member 18 exists in a portion located above the regulating member 18 provided inside. A display unit 15c is provided.

  The rope 21 of each IC tag coupling body 22 protrudes from both end portions 15a and 15b of the pipe 15 protruding into the maintenance pit 16, and is held by a rope holding portion 19 provided in the maintenance pit 16, The top of the maintenance pit 16 is closed with a lid member 17.

  The construction method of such a floor slab 10a is as follows. First, a plurality of IC tags 20 are connected by ropes 21 in accordance with the pitch of the lattice formed by the reinforcing bars 11 and 12 to be embedded, and a plurality of IC tag assemblies 22 is formed. At this time, each IC tag 20 can tolerate the pitch error of the lattice formed by the reinforcing bars 11, 12, the mounting error of the IC tag 20 attached to the rope 21, the pitch error of the regulating member 18 provided on the pipe 15, etc. The rope 21 is attached so as to be movable in the longitudinal direction.

  Next, the IC tag coupling body 22 is inserted into the pipe 15 slightly longer than the interval between the maintenance pits 16 provided at the end of the floor slab 10a, and both end portions 21a of the rope 21 protrude from both end portions 15a and 15b of the pipe 15. At the same time, it is temporarily fixed with a tape or the like so as not to be drawn into the pipe 15.

  Next, the formwork for constructing the floor slab 10a and the maintenance pit 16 is disposed at the construction site, and the reinforcing bars 11 and 12 are disposed therein. At this time, the pipe 15 through which the IC tag connector 22 is inserted is disposed between the longitudinal bars 11 so that both end portions 15a and 15b are located on the side where the maintenance pit 16 is provided.

Then, after placing concrete and curing, remove the formwork.
Then, after temporarily removing the rope 21 at both ends 15a and 15b of the pipe 15 and pulling the rope 21 toward one end 15a, the other IC tag 20 is brought into contact with the regulating member 18 The position of the IC tag 20 is adjusted by pulling toward the end 15 b side, and the adjusted rope 21 is held by the rope holding portion 19 in the maintenance pit 16. Finally, the cover member 17 is attached to the maintenance pit 16 to complete the floor slab 10a, and the floor finishing material 10b is applied to the surfaces of the floor slab 10a and the cover member 17 to complete the floor 10.

  According to such a floor 10, a plurality of IC tags 20 embedded in the floor 10 are connected by a rope 21 to form an IC tag connecting body 22, and both end portions 21 a are protruded and embedded in the floor 10. Since the IC tag connector 22 is inserted into the pipe 15, the plurality of IC tags 20 can be easily arranged. At this time, since the IC tag 20 is not directly embedded, the IC tag 20 can move in the pipe 15, and the rope 21 of the IC tag connector 22 protrudes from the discharged end portions 15 a and 15 b of the pipe 15. The embedded IC tag 20 can be taken out by pulling the protruding rope 21. At this time, when a new IC tag connector 22 is connected to the rope 21 protruding toward the other end 15b and the rope 21 protruding toward the one end 15a is pulled, the IC tag 20 can be easily replaced. Is possible.

  Further, since the IC tags 20 included in the IC tag connector 22 are arranged at equal intervals, a plurality of IC tags 20 can be easily arranged in the pipe 15 at equal intervals. Moreover, when controlling based on the information which the embedded IC tag 20 has, since it can control on the assumption that each embedded IC tag 20 is arrange | positioned at equal intervals, control is easy. is there. In particular, when position control is performed based on the position information of the IC tag 20, more accurate position control can be performed with simpler control.

  In addition, since a plurality of pipes 15 through which the IC tag connector 22 is inserted are provided, it is possible to embed more IC tags 20 easily. In addition, since the plurality of pipes 15 through which the IC tag connector 22 is inserted are arranged along the depth direction and are arranged side by side in the left-right direction intersecting the depth direction, the IC tags 20 are simply connected in a linear shape. Instead, it is possible to disperse and arrange in the entire area of the floor 10.

  At this time, by arranging the plurality of pipes 15 through which the IC tag connector 22 is inserted at equal intervals in the left-right direction, the plurality of IC tags 20 can be easily arranged at equal intervals in the left-right direction. Is possible. Further, when the control is performed based on the information of the embedded IC tag 20, the control can be performed on the assumption that the embedded IC tags 20 are arranged at equal intervals in the left-right direction. Is easy. In particular, when the IC tags 20 are arranged at equal intervals in both the depth direction along which the pipes 15 are arranged and the crossing direction in which the plurality of pipes 15 are arranged, the control is easier. It is possible to control accurately.

  In the pipe 15, a restriction member 18 that is allowed to move when the rope 21 is pulled to one side along the pipe 15 and is restricted to move when the rope 21 is pulled to the other side is attached to the IC tag 20. Since each IC tag 20 is provided in correspondence with each other, the IC tag coupling body 22 to which the plurality of IC tags 20 are coupled is pulled to one side, passed through the regulating member 18, and then pulled to the other side, whereby each IC tag 20 is regulated. It is possible to arrange at a position regulated by. At this time, the IC tags 20 are connected so as to allow an amount of movement that allows an error between the interval between the IC tags 20 and the interval between the regulating members 18 corresponding to each IC tag 20. It is possible to prevent all the IC tags 20 from being positioned at a position where one IC tag 20 is regulated by the regulating member 18, and to position each IC tag 20 using the corresponding regulating member 18. It is possible to arrange in the position.

  Further, since the pipe 15 is arranged so that the reinforcing bars 11 and 12 aligned with the pipe 15 do not overlap on the surface side of the floor 10, communication with the IC tag 20 embedded in the floor slab 10a made of reinforced concrete is performed. Can be carried out from the surface side of the floor 10.

  Further, since the opened maintenance pit 16 in which the end portions 15a and 15b of the pipe 15 are accommodated is closed by the lid member 17, the ends 15a and 15b of the pipe 15 and the IC tag are connected. It is possible to cover the rope 21 of the body 22 and not expose it to the outside. Further, since the lid member 17 can be opened, the IC tag 20 can be exchanged by opening the lid member 17 as necessary. Moreover, since the maintenance pit 16 is recessed with respect to the surface of the floor slab 10a, the pipe 15 having the end portions 15a and 15b protruding into the maintenance pit 16 is bent in the floor slab 10a. Instead, both end portions 15 a and 15 b can be protruded into the maintenance pit 16 by being arranged substantially linearly. For this reason, it is possible to prevent the pipe 15 from interfering with the movement of the IC tag coupling body 22 inserted into the pipe 15, so that the IC tag coupling body 22 is easily moved within the pipe 15. It is possible.

  The above embodiment is for facilitating the understanding of the present invention, and is not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.

That is, both ends 21 a of the rope 21 do not have to protrude from the pipe 15 as long as they are stored in a state where they can be pulled out from the ends 15 a and 15 b of the pipe 15. Further, both end portions 15a and 15b of the pipe 15 are not protruded as long as the end portion 21a of the rope 21 of the IC tag coupling body 22 can be retracted. The end portions 15a and 15b may be exposed on the same surface as the inner surface, or may be exposed in a state of being recessed from the inner surface.
