  It is desirable to connect the tiles in order to prevent falling off due to peeling of the tiles that are attached to the frame using a fixture or the like. However, if it is hardened in advance until it becomes a panel shape as in Patent Document 1, the joint width between the tiles cannot be adjusted, and it takes time to prepare in advance for making the panel shape.

  In the case of the technique in which the connecting member is point-adhered to the back surface of each tile of the unit tile in advance as in Patent Document 2, each tile is supported by the front side mount and the back side connecting member, and the entire unit is like a panel. Since it can be handled, it has the construction advantage of being easier to handle than conventional unit tiles as well as easily adopting the existing handrail construction method. However, although the joint width can be adjusted to some extent, it is within the range of stretchability of the connecting member and is difficult to adjust. Furthermore, since it is necessary to bond the connecting member in advance, it takes time to prepare.

  An object of the present invention is to easily adjust the joint width in order to prevent falling off due to peeling of a tile that has been applied, and to reduce the effort of adhering a connecting member to the back surface of a unit tile in advance. .

According to the present invention, in the unit tile construction method for attaching the unit tile to the wall surface, the connecting member for connecting the tiles is simply placed on the back surface of the unit tile in the step of attaching the unit tile to the wall surface . There is provided a unit tile construction method characterized in that a mortar is applied from above as a state and then the unit tile is attached to a wall surface.

  According to the present invention, it is easy to adjust the joint width in preventing the falling off due to peeling of the applied tile, and it is possible to reduce the trouble of adhering the connecting member to the back surface of the unit tile in advance. .

  FIG. 1 is a partially exploded perspective view of a unit tile construction structure realized by the unit tile construction method of the present invention. In the construction structure example shown in the figure, the unit tile 10 is attached to the wall surface 1 of the building frame by the attaching mortar 30 with the connecting member 20 interposed.

  In the case of this embodiment, the unit tile 10 is unitized by mounting a mount 12 on the surface 11 a of the plurality of tiles 11. In addition, it may replace with the connection in the base_sheet | mounting_paper 12, and the back surface and side surface of the tile 11 may be partially connected with resin etc.

  Each tile 11 has the same shape (square). The mount 12 is made of, for example, a sheet of paper, a resin film, or a net, and a plurality of tiles 11 are arranged and pasted with gaps corresponding to the joint widths in the vertical and horizontal directions. As will be described later, the mount 12 is peeled off after the construction.

Connecting member 20, in this embodiment, but assumes a mesh sheet made of vinylon fibers, laying mortar 30 is acceptable as long as a mesh shape having a permeable alkali resistance on the back of the tile 11. The size of the connecting member 20 is substantially the same as that of the mount 12 and is preferably about 5 cm smaller on each side than the size of the unit tile. The pasting mortar 30 is, for example, a cement mortar to which a pre-prepared pasting mortar or a thickening water retention agent is added.

  The fixture 40 is an instrument that mechanically fixes the unit tile 10 to the wall surface 1. After the unit tile 10 is stuck to the wall surface 1 and the strength of the tension mortar 30 comes out (for example, after two days or more), the fixture 40 passes the connecting member 20 to the joint between the plurality of tiles 11 and passes through the wall surface 1. Connected to. Although not shown in FIG. 1, the joint material is filled in the joint between the tiles 11 after the fixture 40 is disposed.

  Next, a unit tile construction method according to an embodiment of the present invention will be described with reference to FIGS. 2A to 2C and FIGS. 3A and 3B, the left side of each figure is a view of the work on the unit tile 10 from the side, and the right side is the unit tile 10 after the work. It is the figure which looked at from the upper part.

  In this embodiment, one feature is that each tile 11 of the unit tile 10 and the connecting member 20 are not connected in advance by bonding or the like. Then, at the stage of attaching the unit tile 10 to the wall surface 1, the disposing operation of the connecting member 20 is performed. For this reason, as shown to Fig.2 (a), in the construction site, Preferably the work table 2 is provided in the vicinity of the wall surface 1 to which the unit tile 10 is attached, and the mount 12 is adhered thereon. The unit tile 11 is placed with the mount 12 facing down and the back surface 11b of the tile 11 facing up. Although not particularly illustrated, the back surface 11b of the tile 11 is appropriately provided with unevenness (for example, a groove, particularly a dovetail groove) for improving the bonding property with the tension mortar 30.

  The work table 2 may be anything as long as a substantially horizontal plane on which the unit tile 10 can be placed is secured. If the wall surface 1 is near the ground, the work table 2 may be installed on the ground. In addition, when unit tiles 10 are attached to the wall surfaces of the middle and upper floors apart from the ground among the wall surfaces of apartments, etc., they may be provided on a scaffold 100 provided along the wall surface of the building as shown in FIG. it can.

  In the example of FIG. 5, it is assumed that the unit tile 10 is attached to the wall surface 1 near the balcony, and the work platform 101 is provided on the scaffold 100 so as to protrude into the space between the balconies on the upper and lower levels. By using the space formed by the unevenness of the building in this way, an empty space can be effectively used as the installation space for the work table 101.

  Returning to FIG. 2, when the unit tile 10 is placed on the work table 2, the connecting member 20 is placed thereon as shown in FIG. Since the connecting member 20 is only placed on the back surface 11b of the unit tile 10, the tiles 11 are not connected. In addition, since the connection member 20 is only on the back surface 11b of the unit tile 10, there is a possibility that the connection member 20 may be blown off when a strong wind blows. Therefore, it is preferable to provide a windshield around the work table 2. Examples of windbreaks include a curing mesh sheet. In the configuration in which the work platform 101 is provided on the scaffold 100 as in the example of FIG. 5 described above, it is preferable to provide a curing mesh sheet 102 on the scaffold 100 as a windshield as shown in FIG.

  When the connecting member 20 is placed, the mask material 3 is placed thereon as shown in FIG. The mask material 3 is a sheet or plate that opens so that about 90% of the back surface 11b of each tile 11 is exposed and closes the joint, and is used for normal masking.

  Next, the mortar 30 is applied to the back surface 11 b of each tile 11 from above the mask material 3. FIG. 3A shows a process of applying the sticking mortar 30 with the scissors 4. The sticking mortar 30 passes through the connecting member 20 and is applied to the back surface of the tile 11.

  Next, the mask material 3 is removed (FIG. 3B), and the unit tile 10 is attached to the wall surface 1 as shown in FIG. At that time, it is preferable to apply the mortar 30 to the wall surface 1 as shown in FIG. Moreover, it is preferable that the wall surface 1 is ground-treated in an uneven state by, for example, an ultra-high pressure water cleaning method or an MCR method.

  When the unit tile 10 is attached to the wall surface 1, since the connecting member 20 is not bonded to the tiles 11 in advance, most of the tiles 11 are supported by the mount 12, and part of the back surface is the back surface. The connecting member 20 and the tensioning mortar 30 in 11b bear. The unit tile 10 can be attached to the wall surface 1 by holding the upper end portion of the unit tile 10 and suspending it from above as shown in FIG. Thereafter, the mounting operation of the unit tile 10 is completed by peeling the mount 12 from the unit tile 10.

  A series of pasting operations after the pasting mortar 30 is applied to the tile back surface 11b is the same as the conventional masking or the improved masking, but in the case of this embodiment, the pasting mortar 30 is in a fresh state when the operation is completed. Therefore, each tile 11 is not firmly connected by the connecting member 20. Therefore, the position of each tile 11 on the wall surface 1 can be shifted relatively freely, and the joint width can be easily adjusted.

  As described above, in the present embodiment, at the stage of attaching the unit tile 10 to the wall surface 1, the joint width can be easily adjusted by not substantially connecting the tiles 11 with the connecting member 20. Moreover, since the prior preparation which adhere | attaches between the tiles 11 with the connection member 20 conventionally becomes unnecessary, the effort can be reduced. Since the tiles 11 are connected to each other by the connecting member 20 after the hardening mortar 30 is hardened and the strength is increased, it is possible to prevent the individual tiles 11 from falling off due to peeling.

  Next, the construction procedure of the fixture 40 will be described with reference to FIG. 4A and 4B show cross-sectional views of the construction structure along the joint in the vertical direction. After the strength of the tension mortar 30 comes out from the state of FIG. 3 (c), as shown in FIG. 4 (a), the connecting member 20 and the tension mortar 30 are passed from the front side by a drill or the like to the joint where the fixture 40 is attached. Then, the mounting hole 5 reaching the wall surface 1 is drilled. Since the attachment hole 5 can be formed by a drill or the like, the tile 11 is not damaged. The part where the attachment hole 5 is drilled (the attachment part of the fixture 40) has a wide joint width because the intersection of the vertical joint and the horizontal joint is rounded at the corners of each tile. This is desirable.

  When the attachment hole 5 is formed, the fixture 40 is inserted into the attachment hole 5. In this embodiment, the fixture 40 is an L-shaped metal fitting, and one side portion thereof is inserted into the attachment hole 5. The other side portion of the fixture 40 is arranged along the joint. At the time of insertion, the adhesive 6 such as an epoxy resin is attached to either the inner surface of the mounting hole 5 or the fixing tool 40, and the fixing tool 40 can be fixed to the mounting hole 5 by curing the adhesive 6. As a result, the fixture 40 is connected to the wall surface 1.

  Thereafter, the joint material 7 such as joint mortar is filled in the joint (FIG. 4B). The filling of the joint material 7 is performed, for example, by rubbing the joint material 7 from the surface side of the tile 11 into the joint. As soon as the joint material 7 is tightened, the joint material remaining on the surface of the tile 11 is removed with a sponge or the like to complete the construction. Since the fixture 40 is substantially buried in the joint material 7, it is not conspicuous and does not impair the beauty.

  In the present embodiment, since each tile 11 is mechanically fixed to the wall surface 1 via the fixture 40 and the connecting member 20, the anti-peeling performance can be further improved. Note that the greater the number of fixtures 40, the better the drop-off prevention performance. However, about two are sufficient for one unit tile 10 as in this embodiment.

  In the present embodiment, an L-shaped metal fitting is used as the fixture 40. However, various shapes can be adopted, and the surface can be attached to the wall surface 1 by providing irregularities. You may increase the nature. Further, as a method for attaching the fixture 40, a screw-in type or the like can be employed in addition to the method using the attachment hole 5 and the adhesive 6.

<Summary>
The method of attaching unit tiles on site (hand-clad construction method) is overwhelmingly mosaic tiled, and masking and improved masking are also considered to be reliable methods, but they are used as such, but in rare cases Adhesion tension (Vibrato method) is adopted. The tiling method is closely related to the conditions of the target building, the accuracy of the groundwork, the efficiency, and the reliability of bonding, and it can be said that it has been refined as such.

  Establishing the reliability of the construction method requires a long period of about 10 years, a period in which the degree of peeling or peeling due to aging or the like is known after actual use. For example, adhesion is not often used for unit tiles, but because it is tightened with an electric vibration tool, mortar easily turns around the back of the tile, and it has been developed because it has high construction efficiency and high initial adhesion strength. Immediately after that, it spread rapidly as a method of attaching two-cable tiles.

  However, it has been known for some time that there is a tendency to peel and peel off even if it is properly managed, other than problems caused by insufficient management such as increasing the construction speed too much. It was found that the tiles strongly adhere to each other, but the original stress to peel off the tiles at the same time increases, which is a cause of easy peeling due to aging.

  Thus, changing the way tiles are laid out in the past can be risky and generally tends to dislike changes.

The present invention greatly changes the conventional construction method in that it eliminates the process of previously bonding the connecting member to the unit tile in advance, and various studies are necessary in the creation process. . For example,
○ Whether a working space can be secured in the vicinity of the scaffold,
○ When the connecting member is placed on the unit tile at the site, isn't it harmful to workability, such as being blown by wind?
○ Workability when attaching the unit tile to the wall surface (Because the side where the mount is pasted is inside, the polygonal shape warps, so it vibrates while moving to the place where the unit tile is attached after the attachment mortar is attached. Whether misalignment of mortar, etc. is caused by
○ When tightening, part of the connecting member may splash or each tile may move, etc.
○ Area and amount of mortar
Etc.

  The present invention is an invention that has undergone such a study, and is a novel and novel invention in that the connecting member is disposed on the tile at the stage of attaching the unit tile.
