  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing the method of the first embodiment of the present invention, FIG. 2 is a cross-sectional view showing the method of the second embodiment, and FIG. 3 is an IC tag for the concrete form surface of the first embodiment. FIG. 4 is a diagram showing a structure, FIG. 4 is a diagram showing an IC tag structure of a concrete mold surface of a second embodiment, and FIG. 5 is a diagram showing a general form of a non-contact IC tag.

  FIG. 1 is a view showing a method of incorporating an IC tag into a concrete structure (first embodiment), and FIG. 1A is a state in which the IC tag 1 is temporarily fixed to a concrete formwork, FIG. Fig. 1 (C) shows a state after concrete is placed, and Fig. 1 (C) shows a state after the mold is removed.

First, a step of preliminarily solidifying the periphery and back surface of the IC tag with a cement material or other molding material is performed. This is performed for the purpose of preliminarily protecting the periphery and the back surface of the IC tag 1 because the IC tag 1 is easily damaged when the IC tag 1 is directly placed in contact with the cement material and placed in concrete. However, if it is formed too thick and its weight increases, it will be easy to drop off from the concrete mold 30, so the thin plate-shaped molded body 10 is formed. The thickness d of the molded body 10 is preferably in the range of about 3 mm to 30 mm. The purpose is to limit the weight and thickness so as not to peel off, but it may be thicker if peeling does not occur in relation to temporary adhesive strength.
Although the surface area of the molded body 10 is related to the size of the IC tag 1, the IC tag 1 is usually the size of the wallet size card or less, and thus the size including the periphery thereof is about.

  The IC tag 1 is preferably protected by covering the antenna surface with a transparent resin or the like. Usually, the antenna surface of the IC tag 1 is covered with a surface protective film. However, in order to withstand long-term use, it is preferable to further protect and enhance the surface with a thermosetting resin, an ultraviolet curable resin, a glass material, or the like. Because.

  The molded body 10 is preferably configured such that the maximum cross-sectional area portion is located in a portion that becomes the inner side of the concrete with respect to the surface on the surface side of the mold 30. This is to make it easier to peel the IC tag 1 from the surface of the concrete mold 30 after the concrete is placed and solidified. For this purpose, the back surface of the thin plate-shaped molded body 10 has a hook-shaped protrusion 11 as shown by the solid line in FIG. 1A, or the entire molded body as shown by the broken line in FIG. However, it is preferable to mold so as to have a truncated cone shape and have a large cross section at the back. It is not always necessary to enlarge the entire area around the back surface of the IC tag 1, and a part thereof may be enlarged.

Next, as shown in FIG. 1A, a step of temporarily fixing the non-contact IC tag 1 to the surface of the concrete mold 30 is performed. Note that this step may be performed before or after the step of forming the molded body. That is, after the non-contact IC tag 1 is temporarily fixed to the surface of the mold 30, the process of hardening the periphery and back surface of the IC tag with a cement material or other molding material may be performed.
Temporary fixing is performed by temporarily bonding the IC tag 1 to the surface of the mold 30 using an adhesive or pressure sensitive adhesive that does not strongly adhere to the surface of the IC tag 1. At this time, it is necessary to prevent the peel strength between the IC tag 1 and the surface of the mold 30 from being larger than the breaking strength of the hook-shaped protrusion 11 when the surface is peeled off. The concrete formwork 30 can be made of steel or wood.

  As molding materials, cement materials such as ordinary cement, lightweight concrete materials, resin-impregnated concrete materials, inorganic materials such as gypsum, lime, dolomite, clay, ceramics, water-soluble or emulsion type natural or polymer materials For example, cellulose, rubber, polyvinyl alcohol resin, vinyl acetate resin, ethylene-vinyl acetate resin, vinyl chloride-vinyl acetate resin and the like can be used, and these materials can be used alone or in combination. It can also be used after being thermoset with a thermosetting resin such as unsaturated polyester, phenol, melamine, urea, epoxy, or silicone.

  Next, as shown in FIG. 1B, when concrete is placed on the IC tag 1 side in the mold 30, the IC tag 1 and the molded body 10 on the back surface thereof are buried in the ready-mixed concrete. Ready-mixed concrete may be a commonly used material. Since the IC tag 1 is protected by the molded body 10, it is not damaged. If the concrete mold 30 is removed after the concrete material is sufficiently hardened, the molded body 10 is incorporated into the concrete and the IC tag 1 is incorporated into the surface of the concrete structure 35 as shown in FIG. Construction is complete.

  The IC tag 1 includes the name of the construction company, form number, construction position (position in the whole concrete structure), construction date, concrete material placed (type of gravel and other concrete materials, production area, etc.), Any of the internal reinforcement structures, etc., or a combination thereof can be recorded. These records will be useful in pursuing the cause if an abnormal situation appears in the concrete structure later.

  Usually, when embedding an embedded object in concrete so as to appear on the surface, it is possible to attach a member that presses from the internal reinforcement toward the mold side and presses the embedded object against the surface of the mold 30. In many cases, in the assembling method of the first embodiment, it is not necessary to use such a member, and the construction can be completed easily. Moreover, it is not necessary to process the concrete mold 30, and the reuse of the mold 30 is facilitated.

FIG. 2 is a view showing a method of incorporating an IC tag into a concrete structure (second embodiment). FIG. 2A shows a state in which the IC tag 1 is temporarily fixed to a concrete formwork, FIG. Fig. 2 (C) shows a state after concrete is placed, and Fig. 2 (C) shows a state after the mold is removed.
The IC tag 1 is temporarily fixed to the surface of the concrete mold 30 as in the first embodiment. In the second embodiment, the IC tag 1 is temporarily fixed to the flange plate 20 with a plastic screw hole and a plurality of pieces. The bolt 21 is used. That is, the concrete mold 30 is provided with a plurality of flaw holes (holes through which bolts can be loosely passed) 32 that allow the bolts 21 to pass therethrough, and screw holes are provided at portions where the bolts 21 of the flange plate 20 abut, The plurality of bolts 21 are screwed. As shown in FIG. 2A, the IC tag 1 is temporarily fixed while being sandwiched between the concrete mold 30 and the flange plate 20 with the screw holes. It is appropriate to use about four bolts 21 and fix the IC tag 1 vertically and horizontally.

  The threaded flange plate 20 is sufficient if it has a thickness of about 3 mm to 10 mm, but if it is too thin, a screw hole cannot be provided. The size of the flange plate 20 is such that the entire back surface of the IC tag 1 is covered and a screw hole is provided outside the IC tag 1 so as not to penetrate the IC tag 1. The IC tag 1 can be temporarily fixed to the mold 30 even if a combination of a single bolt 21 and a single nut is used at multiple locations. However, when the concrete mold is removed, the nut rotates together with the bolt 21. It tends to be difficult to leave.

  The reason why the flange plate 20 with screw holes is made of plastic is that the metal tag is not used to interfere with the IC tag 1. However, when the flange plate 20 has a thickness of about 10 mm or more, or even when the flange plate 20 itself does not have the thickness, the flange plate side of the IC tag 1 is formed with a thickness of 10 mm or more, the flange A metal foil may be attached to the outer surface of the plate 20 (the surface in contact with the concrete), or may be painted or metallized. Metallic coating refers to conducting coating with a paint containing metal powder such as aluminum paste, and metal deposition refers to conducting deposition with aluminum or the like. When the distance between the IC tag 1 and the metal foil is 10 mm or more, the IC tag 1 is not affected by the metal, but the influence of the rear bar arrangement and the like is eliminated and stable communication is possible. It is.

At this time, as in the case of the first embodiment, the IC tag 1 is preferably protected by covering the antenna surface, the periphery, and the back surface on the surface side with a transparent resin or the like. In order to withstand long-term use, it is preferable that the protection is strengthened by a thermosetting resin, an ultraviolet curable resin, a glass material, or the like.
As the plastic material for the flange plate 20, plate-shaped materials such as vinyl chloride resin, polyester resin, polypropylene resin, acrylic resin, ABS resin, and novolac resin can be used. It is not limited to the plate shape, and may be a molded product formed with the back side being formed into an uneven shape in order to increase the contact area with the concrete.

  Next, as shown in FIG. 2B, concrete 31 is placed on the IC tag 1 side using the concrete mold 30. After the concrete has hardened, a step of leaving the IC tag 1 on the surface of the concrete structure and removing the concrete mold 30 is performed. This step is the same as in the first embodiment, but it is necessary to perform an operation of removing the bolt 21 from the concrete mold 30. When the concrete mold 30 is removed, as shown in FIG. 2C, the flange plate 20 is left in the concrete structure, and the IC tag 1 appears on the concrete surface and is completed. The hole of the bolt 21 remaining on the surface side of the IC tag 1 is embedded or concealed with a decorative nail or the like.

  The incorporation method of the second embodiment can reduce the risk of the IC tag 1 dropping off when placing concrete, compared to the incorporation method of the first embodiment. However, it is necessary to drill holes through which the bolts 21 pass through the concrete mold 30.

5A and 5B are diagrams showing a general form of the non-contact IC tag 1, in which FIG. 5A is a plan view and FIG. 5B is a cross-sectional view through the IC chip 3 portion.
As shown in FIG. 5A, the non-contact IC tag 1 has an antenna pattern 2 formed on a base film 5, and IC chips 3 are attached to both ends 2 a and 2 b of the antenna pattern 2. The IC chip 3 is a normal one having a processing function, a storage function, and an input / output function.
The antenna pattern 2 is a planar coil shape in FIG. 5A, but may be composed of two pieces of patch antennas or dipole antennas. Usually, it consists of a pattern formed by etching a metal foil laminated on the base film 5 or printing with an ink made of a conductive pattern.

As shown in the cross-sectional view of FIG. 5B, the surface of the antenna pattern 2 and the IC chip 3 is covered with the surface protective film 4 with the adhesive layer 6 interposed therebetween. For the surface protective film 4, the same base material as the base film 5 or another plastic film can be used.
When it is incorporated in a concrete structure, if the surface protective film 4 is made of a thin film, it is further hardened with a resin layer or protected with a thicker resin sheet or the like in order to protect it from contact or mischief from the outer surface. Is preferred.

In the above, various plastic films can be widely used as the base film. For example, the following films or composite films thereof can be used.
Polyethylene terephthalate (PET), PET-G (terephthalic acid-cyclohexanedimethanol-ethylene glycol copolymer), polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, polycarbonate, polyamide, polyimide, cellulose diacetate, cellulose triacetate, Polystyrene, ABS, polyacrylate, polypropylene, polyethylene, polyurethane, and the like.
The same material can be used for the surface protective film 4.

Next, an example of the IC tag structure of the concrete mold surface of the present invention will be described.
As a non-contact IC tag, a biaxially stretched PET film having a thickness of 38 μm is used as a base film 5 to form a coiled antenna 2 having an antenna shape of 27 mm × 45 mm, and an IC chip 3 having a thickness of 150 μm is connected to both ends 2a and 2b of the antenna pattern. Attached to. Further, a non-contact IC tag 1 was completed by laminating a biaxially stretched PET film having the same thickness as the base film 5 as a surface protective film 4 on the antenna surface and the IC chip 3 surface (see FIG. 5).

  After the surface protective film 4 of the non-contact IC tag 1 is coated and cured with a polyester thermosetting resin colored so that the thickness after curing is 0.5 mm, the IC tag 1 is attached to the boat. After being placed on the bottom surface of a bottom mold (bottom surface 30 mm × 50 mm, top surface 42 mm × 60 mm, thickness 10 mm), a thermosetting polyester resin was poured and cast. The reason why the colored thermosetting resin or the like is used is to clearly indicate the position of the IC tag by making the surface color different from the concrete surface color after completion of the concrete structure.

FIG. 3 is a diagram showing the IC tag structure of the concrete mold surface of the first embodiment, FIG. 3 (A) is a diagram showing the IC tag molded body 10 after molding, and FIG. 3 (B) is the concrete mold 30. It is a figure which shows the state attached to and shows the state just before concrete placement.
After the molding, the molded body 10 of the non-contact IC tag 1 has a thickness of about 10.5 mm (see FIG. 3A). After affixing a 7 μm thick aluminum foil 12 to the back of the molded body 10, the molded body 10 of the IC tag 1 is bonded to the surface of the wooden concrete formwork 30 with starch paste as shown in FIG. Then, it was temporarily fixed and a mold was formed in a predetermined shape.

First, the fool holes 32 were provided at four positions corresponding to the screw holes 22 of the flange plate 20 of the steel concrete mold 30. This hole 32 is a hole through which the bolt 21 passes loosely and is not provided with a thread groove. The flange plate 20 was made of a vinyl chloride plate having a thickness of 4 mm in a rectangular shape of 50 mm × 80 mm, and provided with screw holes 22 at four positions in the vertical and horizontal directions.

As the non-contact IC tag 1, the same IC tag 1 as prepared in Example 3 was used. In the same manner as in Example 3, the IC tag 1 was molded with a thermosetting polyester resin and the front and back sides were solidified to form a molded body 10 having an overall thickness of about 5.0 mm (FIG. 4A). .
Thereafter, the molded body 10 is placed in a predetermined position in the concrete mold 30 where the fool holes 32 are provided, covered with the previously prepared plastic flange plate 20, and bolts 21 are screwed into the four screw holes 22 to temporarily It fixed (refer FIG. 2, FIG. 4 (B)).
