A structure is known in which a fixing bracket is attached to a large tile (see Patent Document 4).

  Insert a mounting member having a split groove into a mounting hole formed on the back surface of the tile and having a bottom that extends to the back, screw a fixing pin into the inner diameter of the mounting member, and expand and hold the mounting member. A structure for attaching a mounting member to a base is known (see Patent Document 5).

  As another mounting means, a tile mounting structure is known in which a groove is formed on the back surface of a tile, a part of the fixture is inserted into the groove, and the fixture is fixed to the structural wall of the building via the fixture. Yes.

  For example, a holding groove having an ant-like vertical cross-sectional shape is cut in the width direction on the back surface of the tile, and a fixing tool for connecting to a mounting member fixed to the wall is inserted from the side of the holding groove to hold this fixing tool. The structure joined to a tile is known as three-surface restraint applied to the bottom surface of the innermost part of the groove and the engagement surface that is positioned above and below the groove and tapers in the back direction (see Patent Document 6).

JP 2010-13887 A (see FIG. 1) JP-A-6-264594 (see FIG. 4) Japanese Patent Laid-Open No. 7-54461 (see FIG. 6) Japanese Patent Laid-Open No. 10-205058 (see FIGS. 3 and 4) JP-A-9-125653 (see FIGS. 2 and 3) JP-A-7-279361 (see FIG. 1) Japanese Patent Laying-Open No. 2004-244852 (see FIG. 6) JP-A-8-135137 (see FIG. 1) Japanese Patent Laid-Open No. 11-229586 (see FIG. 1) Japanese Patent Publication No. 7-100967 (see FIGS. 1 and 5)

  In the conventional tile attachment means, the means for filling the mortar between the tile and the concrete wall such as concrete and fixing the tile to the structure wall requires work for filling the mortar, and the attachment work is not necessarily required. Not efficient.

  In addition, the conventional mounting structure in which a mounting bolt is screwed into a mounting member inserted into the mounting hole on the back side of the tile and is attached to a structural wall such as concrete via a support fitting by this mounting bolt is bonded with the mortar or the like. The working efficiency is improved compared to the mounting means.

  However, in any of the mounting structures of Patent Documents 1 to 4, a mounting member (fastening member, trunk, anchor nut, etc.) is inserted into a mounting hole formed on the back surface of the tile, and a mounting bolt is attached to the mounting member. Since it is a configuration to be screwed, in order to screw the mounting bolt, a hole such as a drill must be drilled to some extent on the back surface of the tile. Then, the tile may be damaged. This is especially true when the tiles are relatively thin.

  Furthermore, when a commercially available mounting bolt is used, the screw formed on the inner diameter of the expanded mounting member may not be screwed in smoothly and smoothly. There is a possibility that a looseness or a gap is generated between the screw formed on the inner diameter of the mounting member and it is difficult to fix it firmly.

  Further, in the conventional example, as disclosed in Patent Documents 5 to 10, a groove is formed on the back surface of the tile, and a part of the fixture is inserted and attached to the groove, and the structure of the building is provided via the fixture. Since the mounting structure of the tile fixed to the wall surface does not use a screw for mounting the mounting tool to the tile, damage due to drilling does not occur.

  However, in the conventional example, the attachment structure of the fixture to the groove on the back surface of the tile is not necessarily sufficient to be easily attached and firmly attached, and it is considered that there is room for further improvement. .

  In particular, the tile mounting structure described in Patent Document 10 has a structure in which the locking groove recessed in the base panel is a single line with respect to the tile, and the tile will come off unless it is always lifted upward from below by a spring member. From this point of view (the spring member is an indispensable constituent element of the invention), it is considered that the mounting stability is not perfect.

  In addition, the configuration in which the upper inner wall in the locking groove and the upper surface of the projection of the tile that abuts on the inner wall are unevenly fitted is considered to have improved mounting stability. Forming an uneven surface on the inner wall cannot be easily cut.

  An object of the present invention is to solve the above-described conventional problems, and it is possible to easily and securely attach a tile fixture to a tile without causing looseness or looseness. It is an object of the present invention to realize a tile mounting structure that can be firmly fixed to the structural wall of the above by a simple operation.

The vertical portion 28 of the portion 26 is biased toward the inclined upper surface 51 of the lower engagement groove 43.

  As a result, the tile fixture 11 is securely engaged with and attached to the engagement groove 8 of the tile 7 and cannot be removed even if the tile fixture 11 is pulled away from the back surface 12 of the tile 7.

  In the state in which the upper engagement portion 21 and the lower engagement portion 26 of the tile fixture 11 are engaged with the upper engagement groove 42 and the lower engagement groove 43 of the tile 7, respectively, The front end portion and the deepest portion 46 of the upper engagement groove 42 are left in contact with each other and have a margin. Further, the vertical portion 28 of the lower engagement portion 26 and the vertical surface 53 of the lower engagement groove 43 do not come into contact with each other so that there is a margin.

  When removing the tile fixture 11 from the tile 7, the tile fixture 11 may be pulled downward once against the leaf spring 56 and pulled outward.

  As described above, the upper engagement portion 21 and the lower engagement portion 26 of the tile fixture 11 are engaged with the upper engagement groove 42 and the lower engagement groove 43 of the tile 7, respectively. After the fixture 11 is attached, the hook portion 18 of the tile fixture 11 is inserted into the receiving portion 13 of the attachment plate 6 and locked. Thus, the tile 7 and the tile fixture 11 can be mounted on the mounting plate 6 and the tile 7 can be fixed to the structural wall 2 of the building.

  When the tile attachment 11 attached to the tile 7 is engaged with the receiving portion 13 of the attachment plate 6 and attached, the tile 7 is its own weight, and the upper engagement groove 42 and the lower engagement groove 43 are The upper and lower engaging portions 21 and 26 of the tile fixture 11 are engaged with each other in both the upper and lower sides.

  For this reason, the tile 7 is locked and restrained by the tile fixture 11 and does not come off easily. Therefore, the tile 7 is firmly fixed to the structural wall surface 2 of the building and does not come off or peel off.

  In particular, the very characteristic configuration of the tile mounting structure according to the present invention and the remarkable function thereof are pushed toward the structural wall 2 of the building using the weight of the tile itself as follows: In addition, it is difficult to come off from the structural wall of the building.

  That is, since the upper engagement groove 42 and the lower engagement groove 43 are formed to be inclined obliquely upward, the tile 7 has its upper weight and the lower engagement portion 21 of the tile fixture 11 by its own weight. 26, a force that moves downward and relatively shifted toward the tile fixture 11 side acts, so that the tile 7 is pressed against the tile fixture 11 side, and the upper engaging portion 21 and the lower engagement portion are engaged. Engagement of the portion 26 with the upper engagement groove 42 and the lower engagement groove 43 is ensured, and the tile 7 is not easily detached from the structural wall surface 2 of the building and is firmly attached.

  Incidentally, the distance s ′ between the deepest portion 46 of the upper engagement groove 42 and the back surface 12 of the tile 7 is formed to be larger than the horizontal distance s from the vertical portion 22 of the tile fixture body 17 to the tip of the upper engagement portion 21. ing. Further, the distance d ′ between the vertical surface 53 of the lower engagement groove 43 and the back surface 12 of the tile 7 is formed to be larger than the folding width d of the horizontal portion 27 of the lower engagement portion 26 of the fixture.

  Therefore, as described above, the tile 7 is moved by its own weight by being shifted relative to the upper engagement portion 21 and the lower engagement portion 26 of the tile fixture 11 downward and relative to the tile fixture 11 side. Even if the tile 7 is pressed against the tile fixture 11 side, the upper engaging portion 21 and the lower engaging portion 26 are perpendicular to the deepest portion 46 of the upper engaging groove 42 and the lower engaging groove 43. There is no such thing as being pressed against the surface 53.

  In this manner, since the tile 7 is firmly attached to the tile fixture 11 by its own weight, it is not always necessary to attach the leaf spring 56 between the tile fixture 11 and the tile 7 attachment hole.

  However, by mounting the leaf spring 56, synergistically with the effect of the tile 7 due to its own weight, a remarkable effect of pressing the tile fixture 11 upward by the leaf spring 56 and engaging it more firmly occurs. .

  Further, the upper engaging groove 42 and the lower engaging groove 43 of the tile 7 are formed by cutting with a disk disc cutter 47 or the like, but the processed surface is not necessarily smooth and unevenness remains. Therefore, when the tile fixture 11 is mounted, rattling occurs.

  However, by attaching the leaf spring 56, the engagement state between the tile 7 and the tile fixture 11 is made uniform, and rattling at the engagement portion between the tile 7 and the tile fixture 11 is eliminated. 7 and the tile fixture 11 are prevented from being displaced in the lateral width direction.

  In addition, although the operation | work which engages the tile fixture 11 with the engagement groove | channel 8 of the tile 7 may be performed at the construction site which attaches the tile 7, if the tile attachment structure 1 which concerns on this invention is used, the tile 7 will be used. If it is performed in advance on the manufacturing side and the unloading side, the work on the construction site becomes extremely simple, and a short time installation work is possible.

  Note that the tile mounting structure according to the present invention may have a configuration in which mortar or the like is not particularly filled between the tile 7 and the structural wall surface 2 of the building. However, after applying an adhesive to a part of the back surface 12 of the tile 7, the hook portion 18 of the tile fixture 11 is inserted into the receiving portion 13 of the mounting plate 6 and locked, so that the tile is bonded with the adhesive. 7 may be configured such that a part of the rear surface 12 of 7 and the structural wall surface 2 of the building are bonded, and the tile 7 is attached more firmly.

  In the tile mounting structure according to the present invention, the gap between the adjacent tiles 7 may not be filled with joint material. However, it is good also as a structure filled with joint materials, such as mortar normally used, or it is good also as a structure filled with the caulking agent made from rubber | gum or resin.

  As mentioned above, although the form for implementing the tile mounting structure which concerns on this invention was demonstrated based on the Example, this invention is not limited to such an Example, It was described in the claim It goes without saying that there are various embodiments within the scope of technical matters.

  The tile mounting structure according to the present invention having the above-described configuration can also be applied to mounting various tiles fixed to a structural wall of a building, exterior members such as siding boards, roof members, and the like.
