  The tile finishing layer of the outer wall of the building floats and peels off due to the expansion and contraction due to repeated daily changes in temperature and dryness. In addition, there are many problems that tiles are peeled off from the building frame due to external forces such as seismic force, wind pressure, and vehicle vibration. There has been a history of incurring major accidents such as passersby's lives and car damage. In addition, peeling off of the finishing layer such as tiles may expose the structural frame and impair the durability of the building.

  So far, various methods have been proposed to deal with some of these problems, but it is difficult to find an effective and accurate method with a wide range of applications.

  In the conventional general method, drill the hole from the surface side into the joint mortar part of the existing floating tile with the concrete outer wall, insert the anchor pin into the hole, and also inject the resin from the epoxy resin injection hole, the tile There is a method for seeking integration of the finishing layer, the base mortar layer, and the concrete frame. However, the construction period is long and expensive. In addition, this method is not applicable when the concrete mortar layer is preliminarily coated with a base mortar layer as a tile base and is directly tiled.

  On the other hand, in tile direct finishing, for example, (1) removal of the existing tile floating finishing layer and repairing the entire tile to be newly tiled, (2) net or sheet-like covering layer on the entire tile outer wall (3) Drill a hole in the center of each ceramic piece surface of the floating tile, insert the anchor pin, and put the ceramic piece into the frame. (4) A method of embedding a stainless steel plate along the joints around the floating tile and bonding and fixing the tile and the case with an epoxy resin.

  Regarding (4), Japanese Patent Application Laid-Open No. 2001-323638 discloses a pinning hole continuously drilled from a surface of an existing tiled joint to a concrete frame, and an existing joint mortar around the pinning hole. A groove is engraved in the shape of a horizontal letter until it is exposed, and is folded into a tweezers shape made of a steel plate material such as flexible stainless steel such as a shape that fits into the pinning hole and the horizontal letter groove, and the bent overhang A tile peeling prevention connecting material and a method for preventing peeling of existing floating tiles have been proposed in which the shape of the part is formed into a rectangular shape with a square corner.

  Japanese Patent Laid-Open No. 2008-63848 discloses that the existing joint mortar is exposed to the concrete frame from the surface of the existing tiled joint, the vertical end of the tile reaching the concrete frame, and a substantially semicircular horizontal single character or A groove is engraved in the shape of a single vertical character, and a shape that fits in the horizontal or vertical single-character groove portion, that is, a steel plate material such as stainless steel is formed into a substantially semicircular plate having a height less than half the length of the diameter, There has been proposed a connecting member for preventing tile peeling, which has a structure in which a pin portion is integrally formed so as to be substantially T-shaped at substantially the center of a substantially semicircular portion.

  In a similar manner, when the object is not a tile finish but a mortar finish, Japanese Patent Application Laid-Open No. 8-199830 discloses a flexible hairpin-like bifurcated shaft body and an arc shape of the shaft body. Stripping of existing mortar to alleviate moisture permeation resistance due to partial binding of existing mortar to concrete frame and partial removal of organic finishing material with insertion of anti-separation connecting material having rod-like locking member connected to bulge Preventive materials have been proposed.

The housing 30 is bonded and fixed (FIGS. 1B, 2D, and 3C).

  Here, when the adhesive / fixing material is infiltrated into the fiber bundle 23a and integrated, when the adhesive / fixing material is infiltrated and integrated so as to slide into the fiber bundle 23a, the integration is performed as described later. The structure is advantageous as if it were a composite material with improved strength by placing fibers in a synthetic resin, as if it were fiber reinforced plastics (FRP).

  For example, in the groove 13 portion, a fiber bundle 23a bundled in a unidirectional manner on the adhesive / fixing material filled in the groove 13 using a jig having a width of the joint portion 21 such as a spatula is used. By pressing strongly and extending, the adhesive / fixing material can be infiltrated into the fiber bundle 23a and integrated.

  As described above, the adhesive / fixing material infiltrates into the fiber bundle 23a in which a plurality of fibrous materials 28 shown in FIG. 3C and FIG. The converted structure becomes the fibrous floating tile locking material in the present invention.

After that, the surface finishing joint mortar 24a and the like can be applied to this portion from the surface side so that the fibrous floating tile anchoring material of the present invention indicated by reference numeral 24 is not visible from the outside ( FIG. 3 (d)).
As the adhesive / fixing material, one or more of polymer cement paste, polymer cement mortar, epoxy resin, and structural sealant grazing system (SSGS) can be used.

  When using a plurality of types, for example, an epoxy resin is used as an adhesive / fixing material to be injected into the insertion holes 13a, 13b, a polymer cement paste or a polymer cement mortar is used as an adhesive / fixing material to be filled in the groove 13, and the fiber bundle 23a is formed.

Can be adopted.

  As shown in FIG. 4A, the fiber bundle 23a is a bundle of a plurality of fibrous materials 28 aligned in one direction.

  As the fibrous material 28, one or more of nylon fiber, polypropylene fiber, aramid fiber, vinylon fiber, vinylidene chloride fiber, glass fiber, carbon fiber, and stainless steel fiber can be used. When using multiple types, for example, considering a combination in which the properties of each fiber are most effectively exhibited, such as a combination of a plurality of nylon fibers and a plurality of polypropylene fibers combined and bundled in one direction. Can be used.

  As the fiber bundle, a plurality of fibrous materials 28 aligned in one direction are bundled as shown by reference numeral 23a in FIG. 4 (a), and as shown by reference numeral 23b in FIG. 4 (b). As shown by reference numerals 23c and 23d in FIG. 4 (c) and FIG. 4 (d), the fiber bundles 23a and the fiber bundles 23b are twisted. Can be used in which a plurality of are twisted together.

  In the present specification, claims, and drawings, a fiber bundle 23a (FIG. 4A) in which a plurality of fibrous materials 28 aligned in one direction are bundled, is aligned in one direction. A fiber bundle 23b (FIG. 4 (b)) in which a plurality of fibrous materials 28 are twisted together, a fiber bundle 23c (FIG. 4 (c)) in which a plurality of the fiber bundles 23a and fiber bundles 23b are twisted together, 23d (FIG. 4D) and the like may be collectively referred to as “fiber bundle” or “fiber bundle 23”.

  Further, a predetermined amount of the adhesive / fixing material is infiltrated into the fiber bundle 23 in which a plurality of fibrous materials 28 are bundled in one direction, and the infiltrated predetermined amount of the adhesive / fixing material is not yet solidified. It is also possible to use an adhesive / fixing material infiltrating fiber bundle 33 (FIG. 4e). The adhesive / fixing material infiltrating fiber bundle 33 in a state where the predetermined amount of adhesive / fixing material infiltrates into the fiber bundle 23 and the infiltrated predetermined amount of adhesive / fixing material is not yet solidified has flexibility.

  In the case of such an adhesive / fixing material infiltrating fiber bundle 33, the amount of the adhesive / fixing material infiltrating the fiber bundle 23 is such that the adhesive / fixing material infiltrates into the fiber bundle 23 and is integrated as described above. The adhesive / fixing material infiltrating fiber bundle 33 in a state in which the amount is insufficient and is not solidified and in which such an amount of the adhesive / fixing material is infiltrated has flexibility, for example, FIG. 4 (e) Both ends 33a and 33b can be bent into a certain shape as shown. In this case, both ends 33a and 33b are partially mixed with the adhesive / fixing material, so that the plurality of fibrous materials 28 are not disassembled apart and maintain a rod-like form, It can be easily inserted into the insertion holes 13a to 13d.

  4 (a) to 4 (d), the fiber bundles 23 shown in FIGS. 4 (a) to 4 (d) are infiltrated with adhesive / fixing material in advance at both ends of the fiber bundle 23 so that both ends can maintain a rod-like form to some extent. By inserting the ring into the insertion holes 13a and 13b, or by previously fitting and bundling a ring at both ends of the fiber bundle 23, the plurality of fibrous materials 28 are disentangled separately at both ends of the fiber bundle 23. Therefore, it can be easily inserted into the insertion holes 13a and 13b while maintaining the rod-like form.

  In any case, when both ends of the fiber bundle 23 are inserted into the insertion holes 13a and 13b, a thin push rod that enters the insertion holes 13a and 13b is used, and the adhesive / fixing material is infiltrated in advance to some extent. The ends of the fiber bundles 23 in the state of being formed, or the ends of the fiber bundles 23 in the state of being integrated without being disassembled in pieces by fitting a ring and binding the insertion holes 13a, Can be pushed into 13b.

  Although not shown, instead of the fiber bundle 23 described above, a string of synthetic polymer such as nylon, polypropylene, vinylon, or a string formed by bundling a plurality of the strings in one direction. A bundle can also be used.

  As the synthetic polymer string, a single synthetic polymer string having a flat cross section, such as a unidirectional packing string, but compressed into a string shape in a crimped shape can be used. Such a synthetic polymer string is applied to the length of the groove 13 in the longitudinal direction, cut into a length longer than the length of the groove 13 in the longitudinal direction, and inserted into the insertion holes 13a and 13b and the groove 13. Buried.

  Alternatively, such a synthetic polymer string is applied to the length of the groove 13 in the longitudinal direction, and is folded several times in consideration of the length of the groove 13 and the depth of the insertion holes 13a and 13b. Further, it is also possible to use a string-like bundle in which a plurality of the string-like bodies are bundled in a unidirectional manner from one continuous synthetic polymer string-like body.

  In the case of such a string-like body or a bundle of string-like bodies in which a plurality of the string-like bodies are bundled in a unidirectional manner, the string-like body or the string-like body is the same as the adhesive / fixing material infiltrating fiber bundle 33 described above. Adhesive with a predetermined amount of adhesive / fixing material infiltrated into a bundle of string-like bodies bundled in a unidirectional manner, and with the infiltrated predetermined amount of adhesive / fixing material still not solidified It can be used as a fixed material infiltrated string or a bonded / fixed material infiltrated bundle.

  The insertion holes formed at both ends of the groove 13 can be inclined and drilled at right angles from the tile wall as shown in FIG. 2 (e). You can also

  When the above-described adhesive / fixing material-impregnated fiber bundle 33 (FIG. 4E) is used as the fiber bundle 23, the flexible adhesive / fixing material-impregnated fiber bundle 33 is shaped into the grooves 13 and the insertion holes 13a to 13d. 4 (e), the groove 13 and the insertion holes 13a to 13d can be easily embedded and inserted while being arbitrarily deformed as shown in FIG.

  As described above, nylon fiber, polypropylene fiber, or the like is used for the fibrous material 28, and a synthetic polymer string-like body or a string-like body obtained by bundling a plurality of the string-like bodies in a unidirectional manner. Also in the case of bundles, nylon, polypropylene, vinylon, etc. are used as synthetic polymers. Moreover, an epoxy resin or the like is used as an adhesive / fixing material.

  Therefore, a fiber bundle 23 in which a plurality of fibrous materials 28 are bundled in one direction, or a synthetic polymer string or a string in which a plurality of string members are bundled in one direction. The structure in which the adhesive / fixing material is infiltrated and integrated into the body bundle is like a composite material in which the strength is improved by putting fibers in a synthetic resin, just like fiber reinforced plastic (FRP).

  The epoxy resin and structural sealant used mainly as adhesives and fixing materials are organic materials, and the fiber material 28 mainly composed of synthetic fibers, or a string of synthetic polymers or a plurality of such strings are aligned in one direction. They are well-matched (compatible) with bundles of bundles of cords and can be integrated together.

  According to the construction method of the present invention, the space between the end side surfaces of the tiles 20b, 20e, 20c, and 20f, which are floating tiles, and the concrete housing 30, is as if it were fiber reinforced plastic (FRP).
