Description
本発明はタイル貼り面のひび割れを周囲と同化させ、その後、繰返してタイルのひび割れが発生する恐れをなくすと共に、タイル貼り面全体を防水工事し、且つ、内外装面からタイルが剥落して落下させないための内外装用タイルひび割れ修復時に於けるタイル剥落防止及び防水工法に関する。 The present invention assimilates the cracks on the tiled surface with the surroundings, and then eliminates the possibility of repeated cracking of the tile, waterproofs the entire tiled surface, and the tiles fall off from the interior and exterior surfaces and fall. The present invention relates to a tile peeling prevention and waterproofing method for repairing cracks in the interior and exterior tiles.
一般に外装仕上げ材としてタイル貼り仕上げの建物は、高級感あふれ、耐久性にも優れているので、近年多く見受けられる。しかし、長期間に渡る紫外線，雨水，酸性ガス，地震などのさまざまな影響によりタイル面の汚れ，ひび割れ，浮き，剥離，目地部のエフロレッセンスの流出，コンクリートの中性化の進行，そして漏水によるさまざまな劣化現象が見られ、タイル貼り面の適切な補修処置は重要になってきている。このため、現在ではタイル貼り面に撥水性処理や汚れ防止程度の薄膜塗料などが塗布されている場合も多く見受けられるが、高い防水性能は望めなかった。この理由としてはタイル貼り面に透明な塗膜で、且つ厚膜で、更にクラック追従性に優れた防水材がなかったためと考えられる。しかもタイル貼り仕上げされたマンション等に於いては、建設後１０年経過すると、地震による影響やコンクリートの収縮等により、躯体側にひび割れを生じ、且つ、タイル陶片までひび割れが発生し［図１（ａ）参照］、雨水がコンクリート内部まで浸入して白いエフロレッセンスを流出して汚れたものが多く見受けられる。 In general, buildings with tiled finishes as exterior finishing materials are often seen in recent years because they are full of luxury and have excellent durability. However, due to various effects such as ultraviolet rays, rainwater, acid gas, earthquakes, etc. over a long period of time, dirt on the tile surface, cracking, floating, peeling, effluent effusion of joints, progress of neutralization of concrete, and water leakage Various deterioration phenomena have been observed, and appropriate repairing of the tiled surface has become important. For this reason, at present, there are many cases where a water-repellent treatment or a thin-film paint with a degree of dirt prevention is applied to the tiled surface, but high waterproof performance cannot be expected. The reason for this is considered to be that there was no waterproof material having a transparent coating film on the tile-attached surface, a thick film, and an excellent crack following ability. Moreover, in apartments with tiled finishes, when 10 years have passed since construction, cracks have occurred on the frame side due to the effects of the earthquake and concrete shrinkage, and cracks have also occurred to the tile ceramic pieces [Fig. (Refer to (a)], many rainwater infiltrates into the concrete and flows out of the white efflorescence and becomes dirty.
この場合の外壁用タイル貼り面の割れ修復工法としては、一般にひび割れたタイル及び修復作業に必要な最小限のタイル陶片を剥離して撤去し、躯体側のひび割れにエポキシ樹脂などの注入材を注入してコンクリートの奥深くまで浸透させ、ひび割れを埋める工程が行われ、或いは、ひび割れに沿って深くＵカットし、Ｕカットした溝にシーリング材を充填させる工程が行われていた［図１（ｂ）参照］。そして注入材或いはシーリング材が固化後、新たなタイル陶片を、剥離した位置に貼付けるタイル貼り工程が行われ、前記タイル陶片間に目地材が埋められてタイル貼り面の割れ修復工法を終了していた。 In this case, the method of repairing cracks on the tiled surface of the outer wall is generally to peel off and remove the cracked tiles and the minimum tile ceramic pieces required for repair work, and then use an injection material such as epoxy resin for cracks on the housing side. A process of filling and infiltrating deep into the concrete and filling the crack was performed, or a process of U-cutting deeply along the crack and filling the U-cut groove with a sealing material was performed [FIG. )reference]. Then, after the injection material or the sealing material is solidified, a tile attaching process is performed in which a new tile ceramic piece is attached to the peeled position, and a joint material is buried between the tile ceramic pieces to repair the crack of the tile attachment surface. It was finished.
しかしながら、前記ひび割れを埋める工程或いはＵカットした溝にシーリング材を充填させる工程が行われて新たにタイル陶片を貼付けて修復しても、躯体側が一度動いてひび割れた箇所は補強しても地震等で動き易いため、修復箇所のタイル陶片は極めてひび割れが発生し易く、タイル陶片の貼り替えを繰返さなければならなかった。このため、弾性を有した接着剤を使用する方法が施される場合もあるが、有効なひび割れ対策が施されたものがないのが現状である。 However, even if the process of filling the crack or the process of filling the U-cut groove with a sealing material is performed and a new tile ceramic piece is attached and repaired, even if the cracked part is moved and the cracked part is reinforced, the earthquake The tile ceramic pieces at the repaired site are very susceptible to cracking, and it was necessary to repeat the replacement of the tile ceramic pieces. For this reason, there are cases where a method using an adhesive having elasticity is applied, but there is no effective countermeasure against cracks at present.
一方、近年に於いて、地震時にタイル貼りした外壁面からタイルが剥離して落下する事故が頻繁に発生しているため、タイル剥落防止工法が多種提案されている。しかしながら、これらの提案は建築する際に、コンクリート打設面の形状を工夫して地震時にタイルの剥落防止を可能とするものであった。他方、建築済みのタイル貼り面の上から施工する外壁タイル剥落防止工法としては、浮きの発生した場所を確認し、そのタイルや石の中央に孔をあけ、孔内の清掃を行った後、アンカーピンをセットすると共にエポキシ樹脂の接着剤を注入して浮いた空間部に充填させる。そして、外壁タイルを洗い、下塗り（シーラー塗布）が行われ、１層目の剥落防止材を塗る。その後、２層目を塗り、上塗りが行われて仕上げられていた。 On the other hand, in recent years, there have been frequent accidents in which tiles peel and fall from the tiled outer wall surface during an earthquake, and therefore various methods for preventing tile peeling have been proposed. However, these proposals made it possible to prevent the tiles from falling off in the event of an earthquake by devising the shape of the concrete placement surface during construction. On the other hand, as an outer wall tile peeling prevention construction method to be constructed from above the tiled surface that has already been built, after confirming the place where the float occurred, drilling a hole in the center of the tile and stone, and cleaning the hole, An anchor pin is set and an epoxy resin adhesive is injected to fill the floating space. Then, the outer wall tile is washed, undercoating (sealer application) is performed, and a first layer anti-peeling material is applied. After that, the second layer was applied and finished by overcoating.
しかしながら、後施工の前記タイル剥落防止工法はタイルや石の中央に孔をあける際、タイルや石が割れ易く、硬質のものに対しては非常に時間が掛かるものとなっていると共に見た目も悪いものとなっていた。また中央の孔からエポキシ樹脂の接着剤を注入して浮いた空間部に充填させると、タイルの周囲が浮き上がってしまうことがあり、見た目が悪いものとなっていた。更にアンカーピンによって壁側に固定されたタイルは、浮きの発生した場所の補修範囲の剥落防止が可能となっても、補修範囲以外のタイルの剥落の恐れが依然として解消されないものであった。従って、浮きの発生した場所の補修が完了した後に、外壁全面に剥落防止材を塗布する場合も見受けられるが、タイルの剥離強さは、始めに施工した際の壁側との固定状態によって決まり、タイルの貼着力だけが頼りとなり、地震時にタイルが壁側と剥離されると、タイルが個々に落下することはないが、タイル全体の落下或いはタイルの部分的な落下と共に固化した剥落防止材も一緒に落下してしまい、タイルの剥落を完全に防止することは難しいものであった。 However, in the post-installation method, the tile peeling prevention method is easy to break when drilling a hole in the center of a tile or stone, and it takes a very long time for a hard material and also looks bad. It was a thing. In addition, when an epoxy resin adhesive is injected from the center hole and filled into the floating space, the periphery of the tile may be lifted, which makes the appearance worse. Furthermore, the tile fixed to the wall side by the anchor pin can prevent the peeling of the repaired area in the place where the floating has occurred, but the fear of the tiles outside the repairing area still cannot be eliminated. Therefore, it can be seen that after the repair of the place where the floating occurred, the anti-strip material is applied to the entire outer wall, but the peel strength of the tile is determined by the fixed state with the wall side when it is first constructed. If the tile is peeled off the wall side in the event of an earthquake, the tile will not fall individually, but the anti-falling material solidified with the fall of the entire tile or the partial fall of the tile. It was difficult to completely prevent the tiles from falling off.
このため、タイル陶片を撤去せずに、ひび割れに沿って深くＵカットし、Ｕカットした溝に柔軟なパテ材を充填させると共にタイル陶片を擬似的に周囲に同化させる工法が、本発明者によって特開２００６−３４８６８７で「内外装用タイル貼り面の割れ修復工法」として提案したところである。また内外装用タイル貼り面の上から施工して、内外装用からタイルが剥落して落下させないための内外壁のタイル剥落防止工法としては、本発明者が特開２００９−１４４４５５で提案したところである。尚、従来の工法に於いて、タイル剥落防止効果と防水効果が同時に得られる施工方法はなかった。 For this reason, without removing the tile ceramic pieces, a method of deeply U-cutting along the cracks, filling the U-cut groove with a flexible putty material, and assimilating the tile ceramic pieces to the surroundings in the present invention is a method of the present invention. Has been proposed by a person in Japanese Patent Application Laid-Open No. 2006-348687 as “a method for repairing cracks on the inner and outer tile-attached surfaces”. Moreover, the present inventor has proposed in Japanese Patent Application Laid-Open No. 2009-144455 as a tile peeling prevention method for the inner and outer walls in order to prevent the tiles from being peeled off from the inner and outer exteriors by dropping from the inner and outer tiles. In addition, in the conventional construction method, there was no construction method capable of obtaining the tile peeling prevention effect and the waterproof effect at the same time.
本発明はタイルひび割れを周囲と同化させ、その後、繰返してタイルのひび割れが発生する恐れをなくすと共に、軽くて脱落しにくく、且つ、防水効果も同時に得られる内外装用タイルひび割れ修復時に於けるタイル剥落防止及び防水工法を提供することを目的とする。 The present invention makes it possible to assimilate tile cracks with the surroundings, and then eliminates the possibility of repeated tile cracks and is also light and difficult to drop off, and at the same time, the tiles can be removed when repairing tile cracks for interior and exterior tiles, which also provide a waterproof effect. The purpose is to provide prevention and waterproofing methods.
本発明は上記現状に鑑み成されたものであり、つまり、タイル貼り面のひび割れ修復時に於いて、少なくとも、予め擬似的に周囲と同化するように表面を着色すると共にその表面にマスキングテープを貼着し、且つ、可撓性を有したウレタン樹脂製のタイルを弾性接着剤でタイル貼り面に所定枚数貼付け、目地用プライマーを目地部の底面及びタイルの側面に塗布し、そのタイル間に軟質の目地材を目地部に充填させた後、マスキングテープを剥がして、タイルひび割れ修復を終了し、次いでタイル剥落防止及び防水工法を行う。 The present invention has been made in view of the above-described situation.In other words, at the time of repairing cracks on the tile attachment surface, the surface is colored in advance so as to be assimilated with the surroundings in advance and a masking tape is applied to the surface.

図１は本発明の実施形態を示す図であり、この図番について説明する。（１）は内外装壁に貼着されたタイルであるが、貼着されたものとしては、タイルに限定されるものではなく、例えば、レンガや石板などでも良い。又、修復用のタイル（１）としては、可撓性を有したウレタン樹脂製のものを用い、且つ、該タイル（１）は撤去したタイル陶片と同形で且つ同じ大きさのものが良い。このタイル（１）には、擬似的に周囲と同化するように表面を着色させる。この時のタイル（１）の表面には、プライマー塗膜と、周囲のタイル陶片と同化するために調合された塗料で塗布した塗膜と、該塗膜の表面に塗布し形成する透明な防護膜とから成る多層膜が設けられている。この多層膜は本発明者が提案した特開２００４−３３２２８０に於いて形成する多層膜と同じものを設ければ良い。更にタイル（１）の表面には、図２に示すように中間部に剥離用の折返し部（12）を設けたマスキングテープ（11）が貼着されている。この時の折返し部（12）の位置としては、図２（ａ）のように端部よりも少し中央寄りに設けるか、或いは図２（ｂ）のように端部側に設けておくと、剥離し易いものとなる。又、前記タイル（１）の材質をウレタン樹脂とすることにより、表面に着色する塗料の密着性が極めて良いものとなると共に躯体のひび割れの挙動部に対し、追従性の良いものとなり、より一層タイル（１）のひび割れの防止が可能なものとなる。尚、前記タイル（１）の可撓性としては、弾力性を有するものが特に好ましい。 FIG. 1 is a diagram showing an embodiment of the present invention, and this figure number will be described. (1) is a tile attached to the inner and outer walls, but the attached thing is not limited to a tile, and for example, a brick or a stone plate may be used. Further, as the tile (1) for repair, a flexible urethane resin is used, and the tile (1) should be the same shape and the same size as the removed tile ceramic piece. . The surface of the tile (1) is colored so as to be assimilated with the surroundings in a pseudo manner. On the surface of the tile (1) at this time, a primer coating, a coating applied with a paint prepared for assimilation with surrounding tile ceramic pieces, and a transparent coating applied to the surface of the coating are formed. A multilayer film comprising a protective film is provided. The multilayer film may be the same as the multilayer film formed in Japanese Patent Application Laid-Open No. 2004-332280 proposed by the present inventor. Further, on the surface of the tile (1), as shown in FIG. 2, a masking tape (11) provided with a folded back portion (12) for peeling is attached at the intermediate portion. As the position of the folded portion (12) at this time, it is provided slightly closer to the center than the end as shown in FIG. 2 (a), or provided on the end side as shown in FIG. 2 (b). It becomes easy to peel. In addition, by using urethane resin as the material of the tile (1), the adhesion of the paint coloring on the surface becomes extremely good and the followability to the cracking behavior part of the casing becomes better, and further. It becomes possible to prevent the tile (1) from cracking. In addition, as the flexibility of the tile (1), one having elasticity is particularly preferable.
（２）は修復したタイル（１）とタイル（１）との間に軟質の目地材を充填させた目地部である。（３）はステンレス製のアンカーピンであり、該アンカーピン（３）には、外径５ｍｍ前後で長さ３０〜８０ｍｍ前後のステンレス製筒状の鞘と、頭付きステンレス製棒状のピンとから成されているものを用いるのが良い。尚、前記ピンの先端は尖り部が設けられ、鞘内部にピンを挿入して行くと、鞘の下部が開く一体型のアンカーピン（３）を用いるのが好ましい。 (2) is a joint part in which a soft joint material is filled between the repaired tile (1) and the tile (1).

The anchor pin (3) is composed of a stainless steel cylindrical sheath having an outer diameter of about 5 mm and a length of about 30 to 80 mm and a headed stainless steel rod pin. It is good to use what is done. In addition, it is preferable to use the integral anchor pin (3) in which the tip of the pin is provided with a pointed portion and the lower portion of the sheath opens when the pin is inserted into the sheath.
次に本発明のタイルひび割れ修復時に於けるタイル剥落防止及び防水工法を図面に基づいて説明する。先ず、タイルひび割れ修復を図１に示す工程に沿って行う。つまり、図１（ａ）のようにひび割れが生じた場合には、ひび割れたタイル（１）と、修復作業に必要な最小限のタイル（１）を図１（ｂ）のように剥離して撤去させると共にひび割れに沿って深くＵカットし、Ｕカットした溝にシーリング材を充填させる［図１（ｂ）参照］。この時、躯体側のひび割れの修復時、Ｕカットせずに直接ひび割れから注入材を注入して、躯体側のコンクリートの奥深くまで注入材を浸透させておくのが良い。前記シーリング材が固化した後、タイル貼り面を平らにして躯体側のひび割れ修復を終了させる。そして、擬似的に周囲と同化するように表面が着色されると共に可撓性を有するタイル（１）を用意し、それを剥離した位置に、弾性を有した接着剤で貼付ける［図１（ｃ）参照］。その後、目地用プライマーを目地部（２）の底面及び貼付けたタイル（１）の側面に塗布し、タイル（１）間に軟質の目地材を図１（ｄ）に示す斜線部分のように注入して充填し、軟質の目地部（２）が形成される。そして、図２に示す折返し部（12）を指で摘まみ、それを引張ってマスキングテープ（11）をタイル（１）から剥がせば、タイル貼り面を清掃しなくても、その表面はきれいであるので、これで修復作業は完了するのである。 Next, tile peeling prevention and waterproofing methods at the time of repairing tile cracks according to the present invention will be described with reference to the drawings. First, tile crack repair is performed along the process shown in FIG. That is, when a crack occurs as shown in FIG. 1A, the cracked tile (1) and the minimum tile (1) necessary for the repair work are peeled off as shown in FIG. 1B. It is removed and deeply U-cut along the cracks, and the U-cut groove is filled with a sealing material [see FIG. 1 (b)]. At this time, when repairing the crack on the housing side, it is preferable to inject the injecting material directly from the crack without U-cutting, and to infiltrate the injecting material deep into the concrete on the housing side. After the sealant is solidified, the tile attachment surface is flattened and the crack repair on the housing side is completed. Then, a tile (1) having a surface that is colored so as to be assimilated with the surroundings in a pseudo manner and having flexibility is prepared, and is attached to the position where the tile is peeled with an adhesive having elasticity [FIG. c)]. Then, a primer for joints is applied to the bottom surface of the joint part (2) and the side surface of the attached tile (1), and a soft joint material is injected between the tiles (1) as shown by the hatched portion in FIG. 1 (d). Thus, a soft joint portion (2) is formed. Then, if the folded part (12) shown in FIG. 2 is picked with a finger and then pulled to remove the masking tape (11) from the tile (1), the surface is clean even without cleaning the tiled surface. Thus, the repair work is completed.
修復作業終了後、内外装用タイル貼り面の全面に、タイル剥落防止効果及び防水効果を同時に得るための施工を行う。この施工方法を図３、図４に基づいて説明する。先ず始めに、タイル貼りの壁面全体に約５０ｃｍ間隔で縦横にマスキングテープで図３の図中の黒丸で示すようにマーキングする。この時、水性マジックなどの筆記具を使用して、図３の図中の極細線にて目安線を引き、桝目を描く。その桝目の各交点の目地部（２）位置にマーキングしても良い。その後、各マーキング位置にドリルで図４（ａ）に示すような穴をあけるイ）穴あけ工程が行われる。この時の穴の深さは、アンカーピン（３）の鞘の長さよりも１０ｍｍ以上深くするのが好ましい。このようにして全ての各マーキング位置に、上記同様にして穴を穿設しておく。 After the restoration work is completed, construction is performed on the entire surface of the interior and exterior tiles to simultaneously obtain a tile peeling prevention effect and a waterproof effect. This construction method will be described with reference to FIGS. First, the entire tiled wall is marked with a masking tape vertically and horizontally at intervals of about 50 cm as shown by black circles in FIG. At this time, using a writing instrument such as a water-based magic, draw a reference line with a fine line in the drawing of FIG. You may mark in the joint part (2) position of each intersection of the mesh. Thereafter, a drilling step is performed in which holes as shown in FIG. The depth of the hole at this time is preferably 10 mm or more deeper than the length of the sheath of the anchor pin (3). In this manner, holes are formed in all the marking positions in the same manner as described above.
穴加工後、アクリルシリコン系樹脂をタイル貼り面の全面に下塗りとしてシーラーを塗布するロ）下塗り工程が行われる。乾燥後、塗布したシーラーの上に、剥落防止材であるナイロン繊維入りで且つ透明なアクリル樹脂で第１回目の中塗りを図４（ｂ）のように塗布するハ）第１塗膜形成工程が行われる。この時、ナイロン繊維入りで且つ透明なアクリル樹脂塗料としては、例えば発売元の株式会社ヤグチ技工の商品名プラチナコートを用いるのが好ましい。また前記シーラー塗布する下塗り作業はウールローラーで０．１〜０．１５Ｋｇ／ｍ２塗布するのが好ましく、又、第１回目の中塗りとしては、ナイロン繊維入りで且つ透明なアクリル樹脂をゴム鏝で０．４〜０．６Ｋｇ／ｍ２塗布するのが好ましい。このゴム鏝を用いることにより、タイル（１）に凹凸があっても均一に塗布することが可能となる。 After the hole is processed, an acrylic silicon resin is applied as an undercoat to the entire surface of the tile attaching surface. After drying, on the applied sealer, the first intermediate coating is applied with a transparent acrylic resin containing nylon fibers as a peeling prevention material as shown in FIG. 4B. C) First coating film forming step Is done. At this time, as a transparent acrylic resin paint containing nylon fibers, it is preferable to use, for example, a platinum coat of trade name of Yaguchi Technical Co., Ltd. The undercoating operation for applying the sealer is preferably 0.1 to 0.15 Kg / m 2 with a wool roller. For the first intermediate coating, a transparent acrylic resin containing nylon fibers and rubber It is preferable to apply 0.4 to 0.6 kg / m 2 . By using this rubber basket, even if the tile (1) is uneven, it can be applied uniformly.
乾燥して第１塗膜が形成された後、第１塗膜を突き抜いてアンカーピン（３）を例えば、図３に示すＡからＤの穴に挿入すると共にアンカーピン（３）のピンの頭部を打込む二）塗膜固定工程が行われる。この場合、アンカーピン（３）の鞘の下部が拡張してアンカーピン（３）は固定される。またアンカーピン（３）のピンを打込むことによって、形成された第１塗膜の一部が図４（ｃ）のようにアンカーピン（３）と一緒に穴へ引込まれ、第１塗膜が引張られた状態で壁面と固定されるのである。そして図３に示すように全ての穴にアンカーピン（３）を打込む。その後、打込まれたアンカーピン（３）のピンの頭部上面に、目地部（２）と同じ色の無機質の耐候性塗料で図４（ｄ）に示すように塗布されるホ）着色工程を行う。 After drying to form the first coating film, the first coating film is penetrated and the anchor pin (3) is inserted into, for example, holes A to D shown in FIG. 2) The coating film fixing step is performed. In this case, the lower part of the sheath of the anchor pin (3) expands and the anchor pin (3) is fixed. Further, by driving the pin of the anchor pin (3), a part of the formed first coating film is drawn into the hole together with the anchor pin (3) as shown in FIG. Is fixed to the wall surface in a tensioned state. Then, as shown in FIG. 3, anchor pins (3) are driven into all the holes. Thereafter, the top surface of the head of the anchor pin (3) that has been driven in is applied with an inorganic weather-resistant paint having the same color as the joint (2) as shown in FIG. I do.
次にナイロン繊維入りで且つ透明なアクリル樹脂で第２回目の中塗りが図４（ｅ）のように塗布される第２塗膜形成工程を行い、乾燥後、同様にして第３回目の中塗りを行うへ）第２・第３塗膜形成工程を行う。この場合、砂骨ローラーを用いて０．６〜０．８Ｋｇ／ｍ２塗布する。そして透明なアクリル樹脂のトップコートがウールローラーで縦方向と横方向１回ずつ合計で０．２〜０．３Ｋｇ／ｍ２塗布するト）仕上げ工程を行い、壁面全体のタイル剥落防止工程と防水工程は完了するのである［図４（ｆ）参照］。尚、前記塗膜は乾燥すると透明になるので、この透明度を見て乾燥具合をチェックする。また第２塗膜と第３塗膜を分けずに１回で形成させると、透明度が悪くなってしまう。 Next, a second coating film forming step is performed in which the second intermediate coating is applied with a transparent acrylic resin containing nylon fibers as shown in FIG. 4E. After drying, the second coating is performed in the same manner. (To apply) The second and third coating film forming steps are performed. In this case, 0.6 to 0.8 kg / m 2 is applied using a sand bone roller. Then perform 0.2~0.3Kg / m DOO 2 coating) finishing a total topcoat transparent acrylic resin by longitudinal and transverse directions once with wool roller, and waterproof the entire tile spalling prevention step wall The process is completed [see FIG. 4 (f)]. In addition, since the said coating film becomes transparent when dried, the degree of drying is checked by checking this transparency. Moreover, if the second coating film and the third coating film are formed at one time without being divided, the transparency is deteriorated.
このように本実施形態の剥落防止材であるアクリル樹脂の透明塗膜は、第１塗膜がアンカーピン（３）によって穴内部に引込まれており、且つ、第２塗膜と第３塗膜は第１塗膜と一体化されているため、剥落防止用の塗膜がアンカーピン（３）を介して壁側としっかりと固定された状態となるため、地震時にタイル（１）の剥落はナイロン繊維入りの強度の強い塗膜によって防止出来るものとなると共にこの塗膜には高い防水性能が期待できるため、従来の如きタイル面のひび割れ，浮き，剥離，目地部のエフロレッセンスの流出，コンクリートの中性化の進行、そして漏水によるさまざまな劣化現象が殆ど防止可能となる。 Thus, the transparent coating film of the acrylic resin which is a peeling prevention material of this embodiment has the first coating film drawn into the hole by the anchor pin (3), and the second coating film and the third coating film. Since it is integrated with the first paint film, the paint film for preventing peeling is firmly fixed to the wall side via the anchor pin (3), so that the tile (1) is peeled off during an earthquake. Since it can be prevented by a strong coating film containing nylon fibers and this coating film can be expected to have high waterproof performance, the tile surface is cracked, floated, peeled off, efflorescence flows out of joints, concrete, etc. The progress of neutralization and various deterioration phenomena due to water leakage can be almost prevented.
