Abstract
Description
本発明は、建築物タイル張り壁面の補修方法に関する。 The present invention relates to a method for repairing a building tiled wall surface.
ビルやマンション等の建築物の外装材料として、意匠性に優れるタイルを用いることが広く行われている。
タイルは、セメントモルタルを介して躯体と一体化される。
As an exterior material for buildings such as buildings and condominiums, tiles having excellent design properties are widely used.
The tile is integrated with the housing through cement mortar.
しかしながら、タイル施工部分は、経年劣化により、例えば施工後１５年程度を経過すると、一部のタイルが脱落し、あるいは一部のタイルがセメントモルタルから浮き上がる等の現象を生じる。
このような経年劣化を促進する主な原因は、大気中の湿気や雨水等の水分である。水分がタイル間の目地から壁の内部に浸入し、あるいは目地やタイルに生じた亀裂から壁の内部に浸入することにより、さらには浸入した水分が氷結することにより、セメントモルタルを侵食して亀裂を生成し、またタイルの剥離等を生じる。
However, in the tile construction part, for example, when about 15 years have passed since construction, a part of the tiles fall off or a part of the tiles rise from the cement mortar.
The main cause of promoting such aged deterioration is moisture in the atmosphere and moisture such as rainwater. Moisture enters the walls from the joints between the tiles, or enters the walls from the cracks generated in the joints and tiles, and the infiltrated moisture freezes, causing the cement mortar to erode and crack. , And tile peeling or the like occurs.
このようなタイル施工部分の経年劣化を生じたときの補修方法として、通常、樹脂注入、アンカーピンニング、タイル張替え等の各種工法が採用されている。 Various repair methods such as resin injection, anchor pinning, tile replacement, etc. are usually employed as repair methods when such aged construction has deteriorated over time.
ところが、上記の各種工法は、一般に、大規模な補修工事となり、多大の補修費用を必要とする。また、防水性等の観点からは必ずしも十分な補修効果を得られない場合もある。 However, the above-mentioned various construction methods are generally large-scale repair work and require a large repair cost. In addition, there are cases where a sufficient repair effect cannot always be obtained from the viewpoint of waterproofness or the like.
上記の不具合に鑑み、例えば、ＦＲＰ樹脂層を主層とする塗布層をタイル貼り壁の表面に形成する方法が提案されており、この方法によれば、長期間にわたって補修効果を維持することができるとされている（例えば、特許文献１、２参照）。
しかしながら、上記したＦＲＰ樹脂層を主層とする塗布層を形成する方法は、樹脂注入等の各種従来工法に比べて補修工事の規模や費用が軽減されるものの、それでも、依然として補修作業が煩雑であり、補修費用も多大である。 However, the method of forming the coating layer having the FRP resin layer as the main layer described above reduces the scale and cost of repair work compared to various conventional methods such as resin injection, but the repair work is still complicated. Yes, the repair cost is great.
本発明は、上記の課題に鑑みてなされたものであり、補修作業が簡易で、補修費用が安価な建築物タイル張り壁面の補修方法を提供することを目的とする。 The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a method for repairing a building tiled wall surface that is easy to repair and inexpensive to repair.
本発明者は、補修作業が簡易で、補修費用が安価な建築物タイル張り壁面の補修方法について鋭意検討した過程で、ゴム状弾性体材料をタイル張り壁面に塗布する方法を着想した。そして、構造力学的シミュレーションを重ねた結果、この方法によりタイルの脱落を充分に防止できることを見出し、本発明に想達した。 The present inventor has conceived a method of applying a rubber-like elastic material to a tiled wall surface in the process of earnestly studying a method for repairing a building tiled wall surface that is easy to repair and inexpensive to repair. As a result of repeated structural mechanical simulations, it was found that this method can sufficiently prevent the tile from falling off, and the present invention has been conceived.
本発明に係る建築物タイル張り壁面の補修方法は、タイル張り壁面に、透明性を有するゴム状弾性体材料を主成分として含む材料を主塗布層として塗布することを特徴とする。 The method for repairing a building tiled wall surface according to the present invention is characterized in that a material containing a rubber-like elastic material having transparency as a main component is applied to the tiled wall surface as a main application layer.
また、本発明に係る建築物タイル張り壁面の補修方法は、前記主塗布層の塗布厚みが０．１５ｍｍ〜１ｍｍであることを特徴とする。 Moreover, the repair method of the building tiled wall surface which concerns on this invention is that the application | coating thickness of the said main application layer is 0.15 mm-1 mm, It is characterized by the above-mentioned.
また、本発明に係る建築物タイル張り壁面の補修方法は、前記ゴム状弾性体材料がアクリルゴムを主成分とすることを特徴とする。 Moreover, the repair method of the building tiled wall surface which concerns on this invention is characterized by the said rubber-like elastic body material having acrylic rubber as a main component.
また、本発明に係る建築物タイル張り壁面の補修方法は、前記主塗布層を中塗り材として、該中塗り材の下層に少なくとも１層からなる下塗り材を、該中塗り材の上層に少なくとも１層からなる上塗り材を、それぞれ塗布することを特徴とする。 Further, the method for repairing a wall surface of a building tiled according to the present invention is characterized in that the main coating layer is used as an intermediate coating material, and an undercoating material comprising at least one layer is provided as a lower layer of the intermediate coating material, and at least an upper layer of the intermediate coating material.

本発明に係る建築物タイル張り壁面の補修方法は、タイル張り壁面に、透明性を有するゴム状弾性体材料を主成分として含む材料を主塗布層として塗布するため、主塗布層によってタイルを目地に繋ぎ止めることでタイルの脱落を防止することができる。
また、十分な防水効果を得ることができるとともに、補修によってタイルの意匠性が損なわれるおそれも少ない。
In the method for repairing a building tiled wall surface according to the present invention, a material containing a rubber-like elastic material having transparency as a main component is applied to the tiled wall surface as a main application layer. The tiles can be prevented from falling off by tying them together.
In addition, a sufficient waterproof effect can be obtained, and there is little possibility that the design of the tile is impaired by the repair.
本発明に係る建築物タイル張り壁面の補修方法の好適な実施の形態（以下、本実施の形態例という。）について、以下に説明する。 A preferred embodiment (hereinafter, referred to as this embodiment) of a method for repairing a building tiled wall according to the present invention will be described below.
本実施の形態例に係る建築物タイル張り壁面の補修方法は、ビルやマンション等の建築物の躯体の外面に塗布したモルタル層に張り付けた、外装材料としてのタイルが、例えば施工後２０年程度経過したときに、経年劣化によりタイルが脱落することを防止するために行うものである。補修は、タイルの脱落が始まった時点で行なってもよいが、施工後一定期間が経過した時点で予防的に行なうことがより好ましい。 The method of repairing the wall surface of a building tiled according to the present embodiment is a tile as an exterior material attached to a mortar layer applied to the outer surface of a building frame such as a building or an apartment, for example, about 20 years after construction. This is to prevent the tile from dropping off due to aging when it has passed. The repair may be performed at the time when the dropping of the tile starts, but it is more preferable that the repair is carried out preventively when a certain period of time has elapsed after the construction.
本実施の形態例に係る建築物タイル張り壁面の補修方法（以下、単に本発明の補修方法ということがある。）は、タイル張り壁面に、透明性を有するゴム状弾性体材料を主成分として含む材料を主塗布層として塗布するものである。なお、塗膜形成主要素として、ゴム状弾性体材料以外の樹脂、油脂等を含んでもよく、また、分散剤、消泡剤、可塑剤等の塗膜形成副要素や、溶剤等を適宜含んでよい。
これにより、例えばタイルがモルタルから剥離して脱落するおそれがあっても、タイルおよびタイル間の目地の全面にわたって塗布したゴム状弾性体材料によってタイルが目地に繋ぎ止められ、タイルの脱落を防止することができる。
透明性を有するゴム状弾性体材料としては、透明性とゴム状弾性を備えるものである限り適宜の材料を選択して用いることができるが、アクリルゴムを主成分とする材料を用いることがより好ましい。ゴム状弾性体材料として透明性を有する材料を用いることにより、タイルが汚損等するおそれが少なく、また、補修材料として不透明材料を用いたときのようにタイルの意匠性を損なうおそれも少ない。
The repair method for a building tiled wall surface according to the present embodiment (hereinafter, simply referred to as the repair method of the present invention) is mainly composed of a rubber-like elastic material having transparency on the tiled wall surface. The containing material is applied as a main application layer. In addition, as a coating film forming main element, a resin other than a rubber-like elastic material, oils and fats may be included, and a coating film forming sub-element such as a dispersant, an antifoaming agent, a plasticizer, a solvent, etc. It's okay.
Thereby, even if the tile may peel off from the mortar, for example, the tile is fixed to the joint by the rubber-like elastic material applied over the entire joint between the tile and the tile, and the tile is prevented from falling off. be able to.
As the rubber-like elastic material having transparency, an appropriate material can be selected and used as long as it has transparency and rubber-like elasticity. However, it is more preferable to use a material mainly composed of acrylic rubber. preferable. By using a material having transparency as the rubber-like elastic material, the tile is less likely to be stained, and the design of the tile is less likely to be impaired as when an opaque material is used as the repair material.
アクリルゴムは、アクリル酸エステルの重合または共重合により得られるゴム状弾性体をいう。アクリルゴムを主成分とする材料は、例えば、屋上や外壁に防水機能を持たせるために塗布する市販の塗材を用いることができる。これにより、充分な防水効果を得ることができ、外壁中への水分の浸入による劣化の進行を抑制することができる。 Acrylic rubber refers to a rubber-like elastic body obtained by polymerization or copolymerization of an acrylate ester. The material which has acrylic rubber as a main component can use the commercially available coating material apply | coated in order to give a waterproof function to a rooftop or an outer wall, for example. As a result, a sufficient waterproof effect can be obtained, and the progress of deterioration due to the penetration of moisture into the outer wall can be suppressed.
本発明の補修方法において、ゴム状弾性体材料をタイルおよびタイル間の目地の全面に直接塗布してもよいが、例えば使用するゴム弾性体材料がタイルに対して直接充分な付着力を示さない場合等において適宜の接着剤を予め塗布して接着層を形成した上にゴム状弾性体材料を塗布することがより好ましく、また、例えば使用するゴム弾性体材料が紫外線等により物性が劣化しやすい場合等において主塗布層を中塗り材として、中塗り材の下層に下塗り材を、中塗り材の上層に上塗り材を、それぞれ塗布することがさらに好ましい。
ゴム状弾性体材料で形成される主塗布層は１層であってもよく、また、材料種類の異なる複数層であってもよい。また、同様に、下塗り材および上塗り材も、それぞれ１層であってもよく、また、材料種類の異なる複数層であってもよい。さらにまた、これら各層は、同種材料を重ね塗りするものであってもよい。
下塗り材は、例えば、アクリル・シリコン系の塗料を接着材として用い、例えば、３０μｍ〜５０μｍの厚みに塗布する。上塗り材は、例えば、下塗り材と同様にアクリル・シリコン系の塗料を汚損防止および中塗り材保護用材料として例えば、３０μｍ〜１００μｍの厚みに塗布する。
In the repair method of the present invention, the rubber-like elastic material may be directly applied to the entire surface of the tile and the joint between the tiles. However, for example, the rubber elastic material used does not show sufficient adhesion directly to the tile. In some cases, it is more preferable to apply an appropriate adhesive in advance to form an adhesive layer, and then apply a rubber-like elastic material. Further, for example, the rubber elastic material to be used tends to deteriorate in physical properties due to ultraviolet rays or the like. In some cases, it is more preferable to apply the main coating layer as the intermediate coating material, apply the undercoating material to the lower layer of the intermediate coating material, and apply the upper coating material to the upper layer of the intermediate coating material.
The main coating layer formed of a rubber-like elastic material may be a single layer, or may be a plurality of layers with different material types. Similarly, each of the undercoat material and the topcoat material may be a single layer or a plurality of layers having different material types. Furthermore, each of these layers may be formed by repeatedly applying the same material.
As the undercoat material, for example, an acrylic / silicon-based paint is used as an adhesive, and is applied to a thickness of 30 μm to 50 μm, for example. For the top coat material, for example, an acrylic / silicon-based paint is applied to a thickness of 30 μm to 100 μm, for example, as an anti-fouling and intermediate coat material protecting material as in the case of the undercoat material.
下塗り材、中塗り材、および上塗り材の塗布方法は、刷け塗り、ローラーブラシ塗り、吹き付け塗装等の適宜の方法のなかから適宜選択することができる。 The application method of the undercoat material, the intermediate coat material, and the top coat material can be appropriately selected from appropriate methods such as brush coating, roller brush coating, and spray coating.
中塗り材（主塗布層）の厚みは特に限定するものではなく、塗布対象のタイル張り外壁の状況に応じて、適宜好適な厚みを設定することができるが、タイルの落下防止および防水効果を確実に得るためには、厚みが厚いほど好ましい。ただし、中塗り材の厚みが極端に厚すぎると非経済的である。このため、中塗り材の厚みは、好ましくは、０．１５ｍｍ〜１ｍｍである。さらにまた、中塗り材の伸び性能(例えばJIS-A-6021に規定する防水材料の規格を定義している破断時の伸び)が高いほど好ましく、この観点から、例えば、タイル張り壁面の置かれている温度条件において上記破断時の伸びの値として１００％を確保するときは中塗り材の厚みは０．５ｍｍ〜１．０ｍｍが好ましく、４００％を確保するときは０．２ｍｍ〜０．４ｍｍが好ましい。
なお、本発明の補修方法は、例えば寸法が数十ｍｍの方形の小タイルを張った壁面に好適に用いることができるが、これに限らず、上記中塗り材の厚みや、材料を適宜選択することにより、寸法の大きなタイルを張った壁面にも用いることができる。
The thickness of the intermediate coating material (main coating layer) is not particularly limited, and a suitable thickness can be set as appropriate according to the situation of the tiled outer wall to be coated. In order to obtain reliably, it is so preferable that thickness is thick. However, it is uneconomical if the thickness of the intermediate coating material is too thick. For this reason, the thickness of the intermediate coating material is preferably 0.15 mm to 1 mm. Furthermore, it is preferable that the elongation performance of the intermediate coating material (e.g., elongation at break defining the standards for waterproofing materials specified in JIS-A-6021) is higher. From this viewpoint, for example, a tiled wall surface is placed. The thickness of the intermediate coating material is preferably 0.5 mm to 1.0 mm when 100% is secured as the elongation value at the time of breaking under the above temperature conditions, and 0.2 mm to 0.4 mm when 400% is secured. Is preferred.
The repair method of the present invention can be suitably used, for example, on a wall surface with a small square tile with a dimension of several tens of millimeters, but is not limited thereto, and the thickness and material of the intermediate coating material are appropriately selected. By doing so, it can be used also on the wall surface where the tile of the large dimension was stretched.
本実施の形態例に係る建築物タイル張り壁面の補修方法によれば、簡易、かつ安価に建築物タイル張り壁面の補修を行い、タイルの脱落および外壁への水分の浸入の進行を防止することができる。
また、補修作業によって生じうるタイル張り外壁の意匠性を損なうおそれが少ないとともに、従来工法の樹脂注入やアンカーピンニング施工によって生じるタイル張り外壁の意匠性の低下を生じるおそれもない。
According to the method for repairing a wall surface of a building tile according to the present embodiment, repair of the wall surface of the building tile is performed easily and inexpensively, and the progress of the falling of the tile and the infiltration of moisture into the outer wall is prevented. Can do.
In addition, there is little risk of impairing the design of the tiled outer wall that may occur due to repair work, and there is no possibility of causing a decrease in the design of the tiled outer wall caused by resin injection or anchor pinning by a conventional method.
施工後十数年〜二十数年経過して、タイルの脱落が始まり、あるいはセメントモルタルからのタイルの浮き上がりが感じられる建築物のタイル張り外壁８例を対象に、本実施の形態例に係る建築物タイル張り壁面の補修方法を施した。
