The present inventors have been working on the development of an organic-inorganic hybrid bonding method for large-sized floor tiles (see Patent Document 1, for example). In this construction method, after applying a thin layer of organic adhesive to the concrete base, a thick layer of mortar is applied in a short period of time for tiling. In recent years, this method has been applied to floor tiles (600 mm x 150 mm, 600 mm square) in cold regions. It has been confirmed that the improved crimping tension) can be applied efficiently while ensuring sufficient filling performance.

Recently, tiles with a long side exceeding 600 mm are on the market. Large floor tiles with a side of 900 mm or 1200 mm have also come to be seen.

The inventors of the present invention have proposed a bonding method for such large floor tiles with a size exceeding 600 mm that makes it difficult for air to be entrained when bonding the tile surface and the base surface together, and allows air to escape easily when the tiles are pushed in. inside. This method can be expected to have the effect of ensuring the fillability of the mortar during the construction process for larger tiles.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a filling property confirmation method and a filling property confirmation device for an adhesive material according to the present invention will be described in detail below with reference to the drawings. In addition, this invention is not limited by this embodiment.

As described above, the present inventors found that in large floor tiles with a long side exceeding 600 mm, when the tile surface and the base surface are bonded together, it is difficult to entrain air, and when the tiles are pushed in, the air does not flow. We proposed an easy-to-remove bonding method. In this method, as shown in FIG. 1, a tile 10 (finishing material) and a base material 12 made of concrete are pre-applied with an attachment mortar 14 (attachment material), and the attachment mortar 14 on the tile 10 side is smoothed. The tile surface is bonded to the underlying surface before the bonding mortar 14 hardens, and the tile 10 is pushed toward the underlying material 12.例文帳に追加Here, the mortar 14 is not applied to the end portion 10A of the tile surface before bonding. This is to use it as an escape route for the mortar 14 when the tile 10 is pushed in. According to this method, the larger the size of the tile, the higher the filling property of the mortar 14 between the tile surface and the base surface.

In this construction method, the mortar 14 is not adhered around the edge 10A of the tile 10 . Therefore, in the present embodiment, a sensor 18 whose state changes when the mortar 14 touches the corner portion (end portion 10A) of the tile 10 is attached in advance.

When the mortar 14 sticks out from the end portion 10A and comes into contact with the sensor 18 by pressing after the tile surface and the base surface are stuck together, the state of the sensor 18 changes. Through this change in state of the sensor 18, the state of filling in the corner of the tile 10 is monitored and stored as a process inspection record of the fillability of the back surface of the tile.

FIG. 2 is a top view illustrating where fill monitoring by sensor 18 is required. As shown in this figure, when the rectangular tiles 1, 2, . Gender is difficult to ascertain. It is desirable to attach a sensor 18 to such a location to check the filling state of the mortar 14 .

In addition, before applying the mortar 14 to the tile 10, the procedure for attaching the sensors 18 only to the corners where filling monitoring is required may result in a wrong attachment location. Therefore, it is desirable to attach sensors to the corners of all the tiles 10 and monitor all the tiles 10 in order to prevent errors.

The sensor 18 can be of any size and shape as long as it changes state when it comes into contact with the mortar before hardening and can be placed at the edge of the tile. It is more preferable to have Examples of such sensors include a sensor using litmus test paper that changes color when it comes into contact with the mortar (hereinafter referred to as a litmus sensor), and a moisture detection sensor that detects moisture by changing the voltage when it comes into contact with the moisture in the mortar. can be used. Since such sensors are inexpensively available, it is possible to relatively easily and inexpensively check the fillability of the plastering mortar.

<Example 1>
Next, as Example 1 of the present invention, a fillability confirmation method and a fillability confirmation device using a sensor using litmus test paper (litmus sensor) will be described.

The upper part of FIG. 3 (1) shows the state of installation of the litmus sensor, and (2) shows an enlarged view of the upper right part. As shown in these figures, the litmus sensors are pre-wound around the corners of the large floor tiles. In the example shown in the figure, the litmus sensors are provided at the upper left and right corners of the large floor tile made of the acrylic plate, but the litmus sensors may be provided at the upper, lower, left, and right corners. In this configuration, when the large floor tiles are pushed into the substrate, the litmus paper of the litmus sensor is brought into contact with the affixing mortar, and the litmus paper becomes alkaline and turns blue. Fig. 4 (1) shows the state of discoloration in the upper left portion, and Fig. 4 (2) shows the state of discoloration in the upper right portion.

FIG. 5 shows the structure of the litmus sensor. As shown in this figure, the litmus sensor 20 is composed of three layers: a transparent sheet 22, a transparent adhesive glue 24, and a litmus test paper 26, in this order from the top. The transparent sheet 22 has cut lines L so that the parts S1 and S2 can be cut out. When attaching the litmus sensor 20, the litmus sensor 20 is wound around the corner portion P (end portion 10A) of the large floor tile 10 in a U-shape when viewed from the side, and the surface of the large floor tile 10 is attached via the adhesive glue 24. Paste it on the back side. Here, the part S1 side in FIG.

After the sticking mortar 14 is applied to the back surface of the large floor tile 10, the transparent sheet 22 in the portion S1 of FIG. The large floor tile 10 is then pushed in and the exposed litmus paper 26 changes color when the applied mortar 14 contacts the litmus sensor 20 . Since the litmus test paper 26 is connected from the back side to the front side of the large floor tile 10, the litmus test paper 26 on the front side of the large floor tile 10 gradually changes color. As a result, it can be seen that the attachment mortar 14 has filled the entire back side of the large floor tile 10 . After visually confirming this, the transparent sheet 22 of the portion S2 in FIG. 5(2) is peeled off. Since the transparent sheet 22 of the portion S2 is also adhered to the litmus test paper 26 via the adhesive glue 24, the litmus test paper 26 is also removed together with the transparent sheet 22. FIG. As a result, a clean tile surface from which the litmus sensor 20 has been removed appears on the surface side of the large floor tile 10. - 特許庁By doing so, it is possible to check the filling state of the mortar 14 on the back side without peeling off the large floor tile 10 stuck on the base material 12 .

<Example 2>
Next, as Example 2 of the present invention, a method for confirming filling property and a device for confirming filling property using a moisture detection sensor will be described.

The lower part of FIG. 3(1) shows the installation status of the moisture detection sensor. As shown in this figure, moisture detection sensors are attached to the corners of large floor tiles in advance. In the example shown in the figure, the moisture detection sensors are provided at the left and right corners of the bottom of the large floor tile made of an acrylic plate, but the moisture detection sensors may be provided at the top, bottom, left, and right corners. In this configuration, when the large floor tile is pushed into the base material, the moisture detection sensor is brought into contact with the attached mortar, and the voltage value of the moisture detection sensor changes as shown in FIG. 7, for example. Fig. 6 (1) shows an enlarged view of the installation state of the moisture detection sensor, and (2) shows the filling state. In addition, in the legend in FIG. 7, the sensor (right) is the moisture detection sensor at the bottom right corner of the large floor tile, and the sensor (left) is the moisture detection sensor at the bottom left corner of the large floor tile. The detected voltage value of each sensor rises sharply in about 25 seconds from the start of detection. Therefore, it can be seen that the mortar for application reaches the left and right corners at the time of about 25 seconds, and the filling is completed.

In the moisture detection sensor of FIG. 6, the sensor portion is composed of a lead wire, and the lead wire is exposed to the outside of the tile, but the present invention is not limited to such a wired type moisture detection sensor. For example, a wireless type moisture detection sensor may be provided at the edge of the back surface of the tile, and the detection result may be transferred to a data logger or the like outside the tile by wireless communication. As such a wireless type sensor, for example, like the RFID strain measurement system shown in Reference 1 below, those that sense using RFID (registered trademark) tags, and those shown in Reference 2 below A wireless organic sensor system that transfers sensed data externally via a wireless communication standard such as BlueTooth (registered trademark) can be used.

Conventionally, it has been difficult to peel off a large floor tile having a long side of more than 1 m and check the filling property of the mortar by peeling the tile immediately after it is attached to the base surface. Even if the tiles could be peeled off, it was also difficult to reattach the tiles while paying attention to the state of filling. Furthermore, after the mortar has hardened, the tiles are subjected to a hammering test. Considering this point, the larger the tile size, the fewer the number of tiles to be installed, so even if the above sensors are attached to the four corners of each tile to monitor the total number of tiles, it will not cause an excessive increase in cost. Therefore, the method of checking the fillability without removing the tiles as in the present invention is very effective as a quality control method.
