Description

本発明は、凍害によって生じた外壁材のクラック部を被覆する化粧幕板材と、当該クラック部を補修する外壁補修構造及び外壁材の補修方法に関する。 The present invention relates to a decorative curtain plate material that covers a crack portion of an outer wall material caused by frost damage, an outer wall repair structure for repairing the crack portion, and a method for repairing the outer wall material.

従来より、寒冷地の建物において、外壁材の内部に侵入した水が、凍結、膨張して爆裂することにより、外壁材に損傷を与える所謂凍害を引き起こすことがある。水は、外壁材に形成された外傷から外壁材内部へと侵入するが、特に、外壁材の下端面は部材の端部となるため傷がつきやすく、且つ、外壁下端は外壁表面に付着した雨水が表面張力で滞留しやすいため、水はこの下端面から外壁材内部へ浸入することが多い。その結果、外壁材下端部で凍害が発生し、外壁材の表面にはクラックが形成される。一般的に、凍害により損傷を受けた建物外壁は、クラックにパテ材を充填して補修した後、外壁全面を塗装することにより外壁を塗膜で保護し、且つ、美観を保持する。しかしながら、外壁全面の塗装は費用や施工手間がかかるため、施主に大きな負担がかかるという問題があった。そこで、凍害により外壁材下端部に生じたクラックのみを被覆する外壁材の補修構造が提案されている（例えば、特許文献１）。 Conventionally, in a building in a cold region, water that has entered the inside of the outer wall material freezes, expands and explodes, which may cause so-called frost damage that damages the outer wall material. Water invades the inside of the outer wall material from the trauma formed on the outer wall material, but in particular, the lower end surface of the outer wall material becomes the end portion of the member, so that it is easily scratched, and the lower end surface of the outer wall adheres to the outer wall surface. Since rainwater tends to stay due to surface tension, water often infiltrates into the outer wall material from the lower end surface. As a result, frost damage occurs at the lower end of the outer wall material, and cracks are formed on the surface of the outer wall material. Generally, the outer wall of a building damaged by frost damage is repaired by filling cracks with putty material, and then the entire outer wall is painted to protect the outer wall with a coating film and maintain the aesthetic appearance. However, there is a problem that painting the entire outer wall is costly and laborious, which imposes a heavy burden on the owner. Therefore, a repair structure for the outer wall material that covers only the cracks generated at the lower end of the outer wall material due to frost damage has been proposed (for example, Patent Document 1).

特許文献１に記載の発明は、外壁材下端部と、建物基礎との境界に補修用化粧材を設置することにより、外壁材下端部に生じたクラックを隠蔽することができる。 According to the invention described in Patent Document 1, cracks generated in the lower end of the outer wall material can be concealed by installing the decorative decorative material for repair at the boundary between the lower end of the outer wall material and the building foundation.

一方、外壁面の上下階の境界に化粧幕板材を設置することにより、外壁全体の意匠性を向上させることができる発明が知られている（例えば、特許文献２、特許文献３）。これらの発明に記載の化粧幕板材で外壁材に生じたクラックを被覆すれば、外壁材の美観を保持することができる。 On the other hand, there are known inventions in which the design of the entire outer wall can be improved by installing a decorative curtain plate material at the boundary between the upper and lower floors of the outer wall surface (for example, Patent Documents 2 and 3). By covering the cracks generated in the outer wall material with the decorative curtain plate material described in these inventions, the aesthetic appearance of the outer wall material can be maintained.

しかしながら特許文献１に記載の発明は、補修用化粧材によって外壁材のクラックを被覆するものの、クラック自体の補修について記載されておらず、外壁材の劣化が進行する可能性がある。また、補修用化粧材の上端部には、シーリング材を打設するための溝が形成されていないため、補修用化粧材と、外壁材の表面との間に十分な量のシーリングを打設することができない。そのため、シーリング材が劣化しやすく、水が容易に外壁材のクラックへ侵入してしまう虞がある。また、特許文献２及び特許文献３に記載の化粧幕板材は、外壁材表面に生じたクラックを被覆することはできるが、防水性について考慮されていないため、凍害を再発させる可能性が高い。 However, although the invention described in Patent Document 1 covers cracks in the outer wall material with a decorative material for repair, the repair of the cracks themselves is not described, and deterioration of the outer wall material may progress. Further, since a groove for placing the sealing material is not formed at the upper end of the repair decorative material, a sufficient amount of sealing is placed between the repair decorative material and the surface of the outer wall material. Can not do it. Therefore, the sealing material is liable to deteriorate, and water may easily enter the cracks of the outer wall material. Further, the decorative curtain plate materials described in Patent Documents 2 and 3 can cover cracks generated on the surface of the outer wall material, but since waterproofness is not considered, there is a high possibility that frost damage will reoccur.

そこで、本発明は、上述した課題を鑑みてなされたものであって、外壁材のクラック部を被覆する防水性に優れた化粧幕板材と、凍害により損傷した外壁材を補修し、且つ、凍害の再発を効果的に防止する外壁補修構造及び外壁材の補修方法を提供することを目的とする。 Therefore, the present invention has been made in view of the above-mentioned problems, and repairs a decorative curtain plate material having excellent waterproofness for covering a crack portion of an outer wall material and an outer wall material damaged by frost damage, and also causes frost damage.

Therefore, the following description will be omitted.

次に、外壁補修構造８について説明する。図４に示す外壁補修構造８は、凍害により外壁材２下端部の表面２ａに生じたクラック部３を補修するための構造であって、第１平面幕板材１１と、外壁材２の表面２ａ及び第１平面幕板材１１の折曲部１１４の境界部分に打設されるシーリング材６と、を備えている。 Next, the outer wall repair structure 8 will be described. The outer wall repair structure 8 shown in FIG. 4 is a structure for repairing a crack portion 3 generated on the surface 2a of the lower end portion of the outer wall material 2 due to frost damage, and is a structure for repairing the first flat curtain plate material 11 and the surface 2a of the outer wall material 2. And a sealing material 6 to be cast at the boundary portion of the bent portion 114 of the first flat curtain plate material 11.

外壁材２は、工場で所定形状に切断された板状の外装材であり、裏面には予め補強材２１が設置されている。施工現場に搬入された外壁材２は、建物の外壁下地材２２に固定されるが、その際、下端部に専用器具を当接し、バールなどの工具でレベルを調整される。外壁材２の下端面２ｂは、部材の端部となるため、表面２ａと比較して傷がつきやすく、このレベル調整時に生じた細かい傷から水が外壁材２内部へ浸入する。そして、外壁材２内部へ侵入した水は、凍結、膨張して爆裂し、外壁材２の表面２ａにクラック部３を発生させる。このようにして形成されたクラック部３は、補修（後述）され、第１平面幕板材１１によって被覆される。 The outer wall material 2 is a plate-shaped exterior material cut into a predetermined shape at a factory, and a reinforcing material 21 is installed on the back surface in advance. The outer wall material 2 brought into the construction site is fixed to the outer wall base material 22 of the building, and at that time, a special tool is brought into contact with the lower end portion, and the level is adjusted with a tool such as a crowbar. Since the lower end surface 2b of the outer wall material 2 is the end portion of the member, it is more easily scratched than the surface 2a, and water penetrates into the outer wall material 2 from the fine scratches generated during this level adjustment. Then, the water that has entered the inside of the outer wall material 2 freezes, expands and explodes, and a crack portion 3 is generated on the surface 2a of the outer wall material 2. The crack portion 3 thus formed is repaired (described later) and covered with the first flat curtain plate material 11.

第１平面幕板材１１は、上側固定部１１１及び下側固定部１１２を外壁材２の表面２ａに当接してパッキン付きのビス５を打設することにより、外壁材２に固定することができる。このとき、外壁材２の表面２ａと、第１平面幕板材１１の折曲部１１４と、によって溝Ｖが形成される。シーリング材６は、現場打ちされる不定形シーリング材であり、溝Ｖに沿って打設される。このように、溝Ｖを形成することにより、十分な量のシーリング材６を打設することができるので、外壁材２の表面２ａを伝う水が第１平面幕板材１１の上端からクラック部３の補修箇所４へ侵入することを効果的に防止し、凍害の再発を抑制することができる。なお、ここでは第１平面幕板材１１を用いる場合について説明したが、その他の第１化粧幕板材１である第１出隅幕板材１２、第１入隅幕板材１３、及び第２化粧幕板材７を使用してもよい。外壁補修構造８は、建物破風の外壁材２の切り替え部分（図４）の他、図８（ａ）〜（ｄ）に示すように、上階の外壁材２と下階の外壁材２との境界部分、１階外壁材２と基礎Ｂとの境界部分、軒天井Ｃ上方や建物用サッシＤ上方の外壁材２下端部、などに用いられる。 The first flat curtain plate member 11 can be fixed to the outer wall material 2 by contacting the upper fixing portion 111 and the lower fixing portion 112 with the surface 2a of the outer wall material 2 and driving a screw 5 with packing. .. At this time, the groove V is formed by the surface 2a of the outer wall material 2 and the bent portion 114 of the first flat curtain plate material 11. The sealing material 6 is an amorphous sealing material that is cast in the field, and is cast along the groove V. By forming the groove V in this way, a sufficient amount of the sealing material 6 can be cast, so that the water propagating on the surface 2a of the outer wall material 2 flows from the upper end of the first flat curtain plate material 11 to the crack portion 3 It is possible to effectively prevent the invasion of the repaired portion 4 and suppress the recurrence of frost damage. Although the case where the first flat curtain plate material 11 is used has been described here, the first decorative curtain plate material 1, the first outer corner curtain plate material 12, the first entrance corner curtain plate material 13, and the second decorative curtain plate material 1 have been described. 7 may be used. In the outer wall repair structure 8, in addition to the switching portion (FIG. 4) of the outer wall material 2 of the building storm, as shown in FIGS. 8A to 8D, the outer wall material 2 on the upper floor and the outer wall material 2 on the lower floor It is used for the boundary portion of the first floor outer wall material 2 and the foundation B, the lower end portion of the outer wall material 2 above the eaves ceiling C and above the building siding D, and the like.

続いて、本発明にかかる外壁材の補修方法の最良の実施形態について各図を参照しつつ説明する。外壁材の補修方法は、凍害により生じた外壁材のクラック部を補修するための方法である。外壁材の補修方法は、図９に示すように、外壁材２の表面２ａに生じたクラック部３を補修する補修工程（Ｓ１）と、その後、第１化粧幕板材１でクラック部３の補修箇所４を被覆する被覆工程（Ｓ２）と、最後に外壁材２の表面２ａと第１化粧幕板材１との境界にシーリング材６を打設するシーリング工程（Ｓ３）と、を順次施工するものである。 Subsequently, the best embodiment of the method for repairing the outer wall material according to the present invention will be described with reference to each figure. The method of repairing the outer wall material is a method for repairing a crack portion of the outer wall material caused by frost damage. As shown in FIG. 9, the method of repairing the outer wall material includes a repair step (S1) for repairing the crack portion 3 generated on the surface 2a of the outer wall material 2, and then repairing the crack portion 3 with the first decorative curtain plate material 1. A coating step (S2) for covering the portion 4 and finally a sealing step (S3) for placing the sealing material 6 at the boundary between the surface 2a of the outer wall material 2 and the first decorative curtain plate material 1 are sequentially performed. Is.

補修工程（Ｓ１）は、図４に示すクラック部３を補修し、外壁材２の劣化の進行を防止することを目的とする。クラック部３が、正面から見て隙間の見える幅の大きな割れである場合は、まず、カッターで割れに沿ってＶカットを入れ、続いてシーラー材（不図示）を塗布する。そして、クラック部３を埋設するように防水性に優れたパテ材３１を充填し、水がクラック部３に侵入することを防止する。また、クラック部３が隙間の見えない軽微な割れである場合は、クラック部３の端縁から所定間隔（１５ｍｍ〜２５ｍｍ程度）ごとに直径３ｍｍ程度の穴を開け、上方の穴から順に接着剤を注入する。穴又はクラック部３から接着剤が溢れ出ることを確認した後、クラック部３廻りにシーラー材を塗布する。 The purpose of the repair step (S1) is to repair the crack portion 3 shown in FIG. 4 and prevent the deterioration of the outer wall material 2 from progressing. When the crack portion 3 is a crack having a large width in which a gap can be seen when viewed from the front, first, a V-cut is made along the crack with a cutter, and then a sealer material (not shown) is applied. Then, the putty material 31 having excellent waterproofness is filled so as to bury the crack portion 3, and water is prevented from entering the crack portion 3. If the crack portion 3 is a slight crack with no visible gap, holes with a diameter of about 3 mm are made at predetermined intervals (about 15 mm to 25 mm) from the edge of the crack portion 3, and the adhesive is sequentially formed from the upper hole. Inject. After confirming that the adhesive overflows from the hole or the crack portion 3, a sealer material is applied around the crack portion 3.

被覆工程（Ｓ２）では、図４に示すように、補修工程（Ｓ１）で補修されたクラック部３の補修箇所４を第１化粧幕板材１で被覆する。ここでは、第１平面幕板材１１でクラック部３を被覆する場合について説明する。まず、第１平面幕板材１１の折曲部１１４を屋外側へ向けた状態で、補修箇所４を第１平面幕板材１１で被覆する。このとき、第１平面幕板材１１の長さや端縁の形状を調整したい場合は、金のこで切断する。そして、屋外側からパッキン付きのビス５を上側固定部１１１及び下側固定部１１２の第１ビス孔１１ａに挿入し、外壁材２に打設して第１平面幕板材１１を固定する。 In the coating step (S2), as shown in FIG. 4, the repaired portion 4 of the crack portion 3 repaired in the repair step (S1) is covered with the first decorative curtain plate material 1. Here, a case where the crack portion 3 is covered with the first flat curtain plate material 11 will be described. First, the repaired portion 4 is covered with the first flat curtain plate 11 with the bent portion 114 of the first flat curtain plate 11 facing the outdoor side. At this time, if it is desired to adjust the length and the shape of the edge of the first flat curtain plate material 11, it is cut with a gold saw. Then, a screw 5 with packing is inserted into the first screw hole 11a of the upper fixing portion 111 and the lower fixing portion 112 from the outdoor side, and is driven into the outer wall material 2 to fix the first flat curtain plate material 11.

なお、補修箇所４が水平方向へ長く延出する場合や、建物外壁の意匠上、第１平面幕板材１１を水平方向へ延出したい場合は、図１０に示すジョイナー材１４によって第１平面幕板材１１同士を水平方向へ連結することができる。ジョイナー材１４は、第１平面幕板材１１の返し片１１５に該当する部分を除く他は第１平面幕板材１１と同一の断面形状となるように加工されており、第１平面幕板材１１と重ね合わせることができる。また、ジョイナー材１４には、第１平面幕板材１１に形成された第１ビス孔１１ａと整合する位置に第３ビス孔１４ａが形成されている。 If the repaired portion 4 extends in the horizontal direction for a long time, or if the first flat curtain plate material 11 is desired to extend in the horizontal direction due to the design of the outer wall of the building, the joiner material 14 shown in FIG. 10 is used to extend the first flat curtain. The plate members 11 can be connected to each other in the horizontal direction. The joiner material 14 is processed so as to have the same cross-sectional shape as the first flat curtain plate material 11 except for the portion corresponding to the return piece 115 of the first flat curtain plate material 11. Can be overlaid. Further, in the joiner material 14, a third screw hole 14a is formed at a position consistent with the first screw hole 11a formed in the first flat curtain plate material 11.

図１０に示すように、ジョイナー材１４は、第１平面幕板材１１の屋内側の面１１ｃに配置されるとともに、隣り合う第１平面幕板材１１の各端縁１１ｂに跨って設置される。水平方向へ第１平面幕板材１１同士を連結固定する際は、まず、ジョイナー材１４の屋外側の面のうち、一方の第１平面幕板材１１に当接する部分へシーリング材（不図示）を塗布し、ジョイナー材１４と他方の第１平面幕板材１１とを重ね合わせて接着固定する。そして、ビス５を第１ビス孔１１ａ及び第３ビス孔１４ａに挿入して一方の第１平面幕板材１１を外壁材２に固定し、続いて、他方の第１平面幕板材１１を屋外側からジョイナー材１４に重ね合わせる。最後に、一方の第１平面幕板材１１の端縁１１ｂと他方の第１平面幕板材１１の端縁１１ｂとを突き合わせ、他方の第１平面幕板材１を外壁材２にビス固定する。このように、ジョイナー材１４を第１平面幕板材１１の裏あて板とすることにより、第１平面幕板材１１のずれを防止して両幕板材１１同士を精度よく連結することができ、また、隣り合う第１平面幕板材１１の境界から水が容易に浸入することをある程度抑制することができる。なお、ジョイナー材１４は、予め一方の第１平面幕板材１１に接着固定された状態で現場に搬入してもよい。さらに、ジョイナー材１４を両方の第１平面幕板材１１にシーリング材で接着固定し、防水性をより向上させてもよい。 As shown in FIG. 10, the joiner material 14 is arranged on the indoor side surface 11c of the first flat curtain plate material 11 and is installed so as to straddle each end edge 11b of the adjacent first flat curtain plate material 11. When connecting and fixing the first flat curtain plate materials 11 to each other in the horizontal direction, first, a sealing material (not shown) is applied to a portion of the outdoor side surface of the joiner material 14 that abuts on one of the first flat curtain plate materials 11. It is applied, and the joiner material 14 and the other first flat curtain plate material 11 are overlapped and fixed by adhesion. Then, the screw 5 is inserted into the first screw hole 11a and the third screw hole 14a to fix one first flat curtain plate material 11 to the outer wall material 2, and then the other first flat curtain plate 11 is placed on the outdoor side. Overlay on the joiner material 14. Finally, the edge 11b of one first flat curtain plate 11 and the edge 11b of the other first flat curtain plate 11 are butted against each other, and the other first flat curtain plate 1 is fixed to the outer wall material 2 with screws. In this way, by using the joiner material 14 as the backing plate of the first flat curtain plate material 11, it is possible to prevent the first flat curtain plate material 11 from shifting and connect the two curtain plate materials 11 to each other with high accuracy. It is possible to suppress the infiltration of water easily from the boundary between the adjacent first flat curtain plate members 11 to some extent. The joiner material 14 may be brought to the site in a state of being adhesively fixed to one of the first flat curtain plate materials 11 in advance. Further, the joiner material 14 may be adhered and fixed to both first flat curtain plate materials 11 with a sealing material to further improve the waterproof property.

また、第１平面幕板材１１は、ジョイナー材１４を使用することによって、第１出隅幕板材１２及び第１入隅幕板材１３ともそれぞれ水平方向に連結することができる。なお、第２化粧幕板材７においても、第１化粧幕板材１と同様、ジョイナー材１４を使用することにより互いに水平方向へ連結することが可能となる。 Further, the first flat curtain plate material 11 can be connected to the first outer corner curtain plate material 12 and the first inner corner curtain plate 13 in the horizontal direction by using the joiner material 14. As with the first decorative curtain plate material 1, the second decorative curtain plate material 7 can be connected to each other in the horizontal direction by using the joiner material 14.

そして、図１１に示すように、補修箇所４の高さが高く、第１平面幕板材１１のみでは補修箇所４を被覆できない場合は、第２平面幕板材７１を組み合わせることにより補修箇所４を被覆することができる。すなわち、第１平面幕板材１１を外壁材２の下端部に固定した後、第１平面幕板材１１の上方に第２平面幕板材７１を固定することができる。なお、図示例では２種類の平面幕板材１１、７１を用いているが、図１２に示すように、第２平面幕板材７１のみを上下方向に複数設置してもよい。また、外壁材２の部位に応じて各出隅幕板材１２、７２、及び各入隅幕板材１３、７３を上下方向に複数設置してもよい。 Then, as shown in FIG. 11, when the height of the repaired portion 4 is high and the repaired portion 4 cannot be covered only by the first flat curtain plate material 11, the repaired portion 4 is covered by combining the second flat curtain plate material 71. can do. That is, after fixing the first flat curtain plate material 11 to the lower end portion of the outer wall material 2, the second flat curtain plate material 71 can be fixed above the first flat curtain plate material 11. In the illustrated example, two types of flat curtain plate members 11 and 71 are used, but as shown in FIG. 12, a plurality of only the second flat curtain plate members 71 may be installed in the vertical direction. Further, a plurality of outside corner curtain plate members 12, 72 and each inside corner curtain plate members 13, 73 may be installed in the vertical direction depending on the portion of the outer wall material 2.

シーリング工程（Ｓ３）は、外壁材２と第１平面幕板材１１との境界から水が補修箇所４へ侵入することを防止するためのものである。すなわち、図４に示すように、外壁材２の表面２ａと第１平面幕板材１１とによって形成された溝Ｖに、シーリング材６を打設し防水性を向上させる。このとき、シーリング材６は、上端面６ａが、第１平面幕板材１１の折曲部１１４の上端１１４ａから外壁材２の表面２ａに向かって上り勾配となるように打設される。シーリング材６の上端面６ａにこのような勾配をつけることによって、外壁材２の表面２ａを伝い落ちてきた水をより確実に下方へ流れ落とすことができ、防水性を向上させることができる。また、図１１及び図１２に示すように、第１平面幕板材１１や第２平面幕板材７１を上下方向へ設置した場合は、それぞれの溝Ｖにシーリング材６を打設することにより、一層防水性を向上させることができる。 The sealing step (S3) is for preventing water from entering the repaired portion 4 from the boundary between the outer wall material 2 and the first flat curtain plate material 11. That is, as shown in FIG. 4, the sealing material 6 is cast into the groove V formed by the surface 2a of the outer wall material 2 and the first flat curtain plate material 11 to improve the waterproof property. At this time, the sealing material 6 is cast so that the upper end surface 6a has an upward slope from the upper end 114a of the bent portion 114 of the first flat curtain plate material 11 toward the surface 2a of the outer wall material 2. By providing such a gradient on the upper end surface 6a of the sealing material 6, the water that has flowed down the surface 2a of the outer wall material 2 can be more reliably flowed downward, and the waterproof property can be improved. Further, as shown in FIGS. 11 and 12, when the first flat curtain plate material 11 and the second flat curtain plate material 71 are installed in the vertical direction, the sealing material 6 is placed in each groove V to further increase the thickness. The waterproof property can be improved.

このように、本願の外壁材の補修方法は、クラック部３を補修したうえで補修箇所４を第１平面幕板材１１で被覆するため、外壁材２の劣化の進行を確実に抑制するとともに凍害の再発を効果的に防止することができる。また、クラック部３のみを被覆するので、建物外壁全面を塗装する場合と比較して、補修にかかるコストを大幅に抑制することができる。 As described above, in the method of repairing the outer wall material of the present application, since the crack portion 3 is repaired and the repaired portion 4 is covered with the first flat curtain plate material 11, the progress of deterioration of the outer wall material 2 is surely suppressed and frost damage is caused. Can be effectively prevented from recurring. Further, since only the crack portion 3 is covered, the cost for repair can be significantly suppressed as compared with the case where the entire outer wall of the building is painted.

本発明の実施の形態は上述の形態に限ることなく、本発明の思想の範囲を逸脱しない範囲で適宜変更することができる。 The embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the idea of the present invention.
