特許文献１に記載されるような壁では、経年劣化により接着剤の接着力が低下し、アルミ板が熱膨張したときにアルミ板が部分的に壁本体から浮き上がる場合がある。この場合、壁の外観が悪化する懸念がある。 In the wall as described in Patent Document 1, the adhesive strength of the adhesive is reduced due to aging, and the aluminum plate may partially lift from the wall body when the aluminum plate is thermally expanded. In this case, there is a concern that the appearance of the wall is deteriorated.

そこで、壁本体から浮き上がった部位を含むアルミ板を除去し、新しいアルミ板を接着剤によって壁本体の外側に取り付けることが考えられるが、壁自体が複雑な組立てにより構成されている場合や、壁内に配管や配線等が設けられている場合には、この作業は非常に煩雑なものとなる。 Therefore, it is conceivable to remove the aluminum plate including the part lifted from the wall main body and attach a new aluminum plate to the outside of the wall main body with an adhesive. However, when the wall itself is configured by complicated assembly, When piping, wiring, etc. are provided in the inside, this work becomes very complicated.

本発明の目的は、煩雑な作業を伴うことなく、壁の外観を改善することが可能な壁補修方法を提供することである。 The objective of this invention is providing the wall repair method which can improve the external appearance of a wall, without accompanying a complicated operation | work.

前記課題を解決するための手段として、本発明は、壁本体と、前記壁本体の外側に取り付けられたアルミニウムないしアルミニウム合金からなる既設アルミ板と、を有する壁を補修する方法であって、アルミニウムないしアルミニウム合金からなり、前記既設アルミ板のうち前記壁本体から浮き上がった浮き上がり部を覆う形状を有する補修用アルミ板を準備する準備工程と、前記浮き上がり部を覆うように前記既設アルミ板の外側に前記補修用アルミ板を位置決めする位置決め工程と、前記補修用アルミ板及び前記既設アルミ板を貫通した状態で前記補修用アルミ板を前記既設アルミ板の外側に固定可能な固定具によって前記補修用アルミ板を前記既設アルミ板の外側に固定する補修用アルミ板固定工程と、前記補修用アルミ板の外面及び前記固定具の外面のうち少なくとも前記補修用アルミ板の外面に塗装する塗装工程と、を含む、壁補修方法を提供する。 As means for solving the above-mentioned problems, the present invention is a method for repairing a wall having a wall main body and an existing aluminum plate made of aluminum or an aluminum alloy attached to the outside of the wall main body. Or a preparatory step of preparing an aluminum plate for repair having a shape that covers the raised portion that is lifted from the wall body of the existing aluminum plate, and the outside of the existing aluminum plate so as to cover the raised portion. A positioning step for positioning the repairing aluminum plate, and the repairing aluminum plate by a fixture capable of fixing the repairing aluminum plate to the outside of the existing aluminum plate while penetrating the repairing aluminum plate and the existing aluminum plate. A repairing aluminum plate fixing step for fixing the plate to the outside of the existing aluminum plate, an outer surface of the repairing aluminum plate, and Serial including a coating step of coating the outer surface of at least the repair aluminum plate of the outer surface of the fixture, providing a wall repairing method.

本外壁補修方法では、既設アルミ板の浮き上がり部を覆うように補修用アルミ板が取り付けられ、少なくともその補修用アルミ板の外面に塗装が施されるという簡単な作業で壁の外観が改善される。 In this exterior wall repair method, a repair aluminum plate is attached so as to cover the raised portion of the existing aluminum plate, and at least the exterior surface of the repair aluminum plate is painted, so that the appearance of the wall is improved. .

この場合において、前記準備工程では、前記補修用アルミ板として、前記既設アルミ板の全域を覆う形状を有するものを準備し、前記位置決め工程では、前記既設アルミ板の外面の全域を覆うように前記補修用アルミ板を位置決めすることが好ましい。 In this case, in the preparation step, as the repair aluminum plate, one having a shape covering the entire area of the existing aluminum plate is prepared, and in the positioning step, the entire area of the outer surface of the existing aluminum plate is covered. It is preferable to position the aluminum plate for repair.

このようにすれば、既設アルミ板の外面の全域が補修用アルミ板によって覆われるので、既設アルミ板のうち浮き上がり部を含む部位が部分的に補修用アルミ板によって覆われる場合（既設アルミ板と補修用アルミ板との境界が外観に表れる場合）に比べ、壁の外観が向上する。 In this way, since the entire outer surface of the existing aluminum plate is covered with the repair aluminum plate, the portion including the raised portion of the existing aluminum plate is partially covered with the repair aluminum plate (with the existing aluminum plate and The appearance of the wall is improved compared to the case where the boundary with the repair aluminum plate appears in the appearance.

また、前記壁補修方法において、前記位置決め工程の前に、前記補修用アルミ板を取り外し可能な状態で仮保持することが可能な仮保持部材を前記既設アルミ板の外面に取り付ける仮保持部材取付工程をさらに含むことが好ましい。 Further, in the wall repairing method, before the positioning step, a temporary holding member attaching step for attaching a temporary holding member capable of temporarily holding the repairing aluminum plate in a removable state to the outer surface of the existing aluminum plate It is preferable that it is further included.

このようにすれば、位置決め工程において補修用アルミ板が既設アルミ板の外面に仮保持されるので、補修用アルミ板固定工程での補修用アルミ板の固定が容易になる。 By doing so, the repair aluminum plate is temporarily held on the outer surface of the existing aluminum plate in the positioning step, so that the repair aluminum plate can be easily fixed in the repair aluminum plate fixing step.

さらに、前記壁補修方法において、前記準備工程では、前記補修用アルミ板として、互いに対向する縁部を有し、これら縁部同士が互いに接触した状態で前記浮き上がり部を覆う形状を有する第１アルミ板及び第２アルミ板を準備し、前記位置決め工程では、前記第１アルミ板の縁部と前記第２アルミ板の縁部とが互いに接触する状態で前記第１アルミ板及び前記第２アルミ板を前記仮保持部材に保持させることが好ましい。 Furthermore, in the wall repairing method, in the preparing step, as the aluminum plate for repairing, a first aluminum having a shape that covers edges that face each other and covers the raised part in a state where these edges contact each other. A plate and a second aluminum plate are prepared, and in the positioning step, the first aluminum plate and the second aluminum plate in a state where the edge of the first aluminum plate and the edge of the second aluminum plate are in contact with each other. Is preferably held by the temporary holding member.

このようにすれば、既設アルミ板のうち浮き上がり部を含む部位の面積が比較的大きな場合や、補修のための作業スペースが限られた状況であっても、効率的に補修を行うことができる。また、第１アルミ板の縁部と第２アルミ板の縁部とが互いに接触しているので、これら縁部同士の境界へのシーリングが不要となる。 In this way, even when the area of the part including the raised portion of the existing aluminum plate is relatively large or when the work space for repair is limited, the repair can be performed efficiently. . Moreover, since the edge part of a 1st aluminum plate and the edge part of a 2nd aluminum plate are mutually contacting, the sealing to the boundary of these edge parts becomes unnecessary.

また、前記壁補修方法において、前記位置決め工程の前に、前記既設アルミ板のうち前記浮き上がり部を含む部位を除去する除去工程をさらに含むことが好ましい。 The wall repair method preferably further includes a removing step of removing a portion including the raised portion of the existing aluminum plate before the positioning step.

このようにすれば、特に既設アルミ板の損傷が激しい場合（浮き上がりが大きい場合）においても、位置決め工程において既設アルミ板の外側に補修用アルミ板を位置決めした際の既設アルミ板の補修用アルミ板への接触が回避されるので、補修用アルミ板の位置決めが容易になり、さらに、壁の外観が向上する。 In this way, even when the existing aluminum plate is severely damaged (when the lift is large), the repair aluminum plate of the existing aluminum plate when the repair aluminum plate is positioned outside the existing aluminum plate in the positioning process. Therefore, the positioning of the repair aluminum plate is facilitated, and the appearance of the wall is improved.

また、前記壁補修方法において、前記位置決め工程の後でかつ前記補修用アルミ板固定工程の前に、前記固定具を取り付けるための穴を前記補修用アルミ板、前記既設アルミ板及び前記壁本体に形成する穴形成工程をさらに含み、前記補修用アルミ板固定工程では、前記固定具として、前記穴の直径よりも小さな外径を有する筒部と、前記筒部の基端部から当該筒部の径方向の外向きに張り出すとともに前記穴の直径よりも大きな外形を有する押付部と、を有するブラインドリベットを用い、前記押付部によって前記補修用アルミ板が前記既設アルミ板に押し付けられかつ前記筒部が前記穴に挿入された状態で前記筒部の先端部が前記穴の直径よりも大きな外形となるように前記筒部の先端部を塑性変形させることによって前記補修用アルミ板を前記既設アルミ板の外側に固定することが好ましい。 Further, in the wall repairing method, after the positioning step and before the repairing aluminum plate fixing step, a hole for attaching the fixing tool is provided in the repairing aluminum plate, the existing aluminum plate and the wall body. A hole forming step to be formed; in the repairing aluminum plate fixing step, as the fixture, a cylindrical portion having an outer diameter smaller than the diameter of the hole, and a base end portion of the cylindrical portion, A blind rivet having a pressing portion that projects outward in the radial direction and has an outer shape larger than the diameter of the hole is used, the repair aluminum plate is pressed against the existing aluminum plate by the pressing portion, and the cylinder The repair aluminum is obtained by plastically deforming the tip of the cylindrical portion so that the tip of the cylindrical portion has an outer shape larger than the diameter of the hole in a state where the portion is inserted into the hole. It is preferably fixed to the outside of the existing aluminum plate.

このようにすれば、補修用アルミ板の既設アルミ板への接続強度を確保しながら壁の外観を向上させることができる。具体的に、ブラインドリベットの筒部の先端部は、壁本体に形成された穴の直径よりも大きな外形となるまで塑性変形するので、補修用アルミ板、既設アルミ板及び壁本体に形成する穴の直径を小さくすることができ、これにより外観上目立ちにくい固定具（比較的小さな外形を有する押付部を有する固定具）を選択することが可能となる。 If it does in this way, the external appearance of a wall can be improved, ensuring the connection intensity | strength of the aluminum plate for repair to the existing aluminum plate. Specifically, since the tip of the cylindrical part of the blind rivet is plastically deformed until it has an outer shape larger than the diameter of the hole formed in the wall body, the repair aluminum plate, the existing aluminum plate, and the hole formed in the wall body Accordingly, it is possible to select a fixture that is not noticeable in appearance (a fixture having a pressing portion having a relatively small outer shape).

また、前記壁補修方法において、前記壁は、前記壁本体の内側に前記壁本体から空間を置いて配置された内側壁本体と、前記内側壁本体の内側に取り付けられたアルミニウムないしアルミニウム合金からなる内側既設アルミ板と、をさらに有し、前記穴形成工程では、前記補修用アルミ板から前記壁本体までの範囲にのみ前記穴を形成することが好ましい。 Further, in the wall repairing method, the wall is made of an inner wall body disposed inside the wall body with a space from the wall body, and aluminum or an aluminum alloy attached to the inner side of the inner wall body. It is preferable to further include an inner existing aluminum plate, and in the hole forming step, the hole is formed only in a range from the repair aluminum plate to the wall body.

このようにすれば、内側壁本体及び内側既設アルミ板を有する壁（バルコニー壁等）において、内側壁本体及び内側既設アルミ板を損傷させることなく壁の外観を向上させることができる。 If it does in this way, in the wall (a balcony wall etc.) which has an inner side wall main part and an inner side existing aluminum plate, the external appearance of a wall can be improved, without damaging an inner side wall main body and an inner side existing aluminum plate.

以上のように、本発明によれば、煩雑な作業を伴うことなく、壁の外観を改善することが可能な壁補修方法を提供することができる。 As described above, according to the present invention, it is possible to provide a wall repair method that can improve the appearance of a wall without complicated operations.

The ball portion 77 has an outer shape smaller than the diameter of the hole and larger than the inner diameter of the cylindrical portion 72, and can plastically deform the distal end portion 72b of the cylindrical portion 72 when the shaft portion 76 is pulled out from the cylindrical portion 72. Have high rigidity.

補修用アルミ板固定工程では、図８に示される取付工具Ｔによって固定具７０（ブラインドリベット）が取り付けられる。なお、図８は、取付工具Ｔの例を示すものであり、取付工具Ｔはこれに限られない。具体的に、補修用アルミ板固定工程では、まず、玉部７７を先頭にして固定具７０が穴に挿入される。そして、筒部７２の先端部７２ｂが壁本体１０の内面よりも内側に位置する状態で取付工具Ｔによって軸部７６が外側に引き抜かれる。そうすると、玉部７７がリベット本体７１に対して外向きに相対変位し、これにより筒部７２の先端部７２ｂが穴の直径よりも大きな外形となるように塑性変形する（図９を参照）。筒部７２のうち塑性変形した部位は、壁本体１０の内面に当接している。この状態で、押付部７３が補修用アルミ板５０を既設アルミ板３０の外面に押し付ける。換言すれば、固定具７０は、前記塑性変形した部位と押付部７３とによって補修用アルミ板５０、既設アルミ板３０及び壁本体１０を壁本体１０の厚さ方向の両側から挟持している。その後、取付工具Ｔによって軸部７６の引き抜きを継続することにより、軸部７６が破断する。軸部７６の破断面は、筒部７２内に形成される。 In the repairing aluminum plate fixing step, the fixing tool 70 (blind rivet) is attached by the attaching tool T shown in FIG. FIG. 8 shows an example of the attachment tool T, and the attachment tool T is not limited to this. Specifically, in the repair aluminum plate fixing step, first, the fixing tool 70 is inserted into the hole with the ball portion 77 as the head. Then, the shaft portion 76 is pulled out by the attachment tool T in a state where the distal end portion 72b of the cylindrical portion 72 is located inside the inner surface of the wall body 10. Then, the ball portion 77 is displaced relative to the rivet main body 71 outward, and plastically deforms so that the distal end portion 72b of the cylindrical portion 72 has an outer shape larger than the diameter of the hole (see FIG. 9). The plastically deformed portion of the cylindrical portion 72 is in contact with the inner surface of the wall body 10. In this state, the pressing portion 73 presses the repair aluminum plate 50 against the outer surface of the existing aluminum plate 30. In other words, the fixture 70 holds the repair aluminum plate 50, the existing aluminum plate 30, and the wall body 10 from both sides in the thickness direction of the wall body 10 by the plastically deformed portion and the pressing portion 73. Thereafter, the shaft 76 is broken by continuing the pulling of the shaft 76 with the mounting tool T. A fracture surface of the shaft portion 76 is formed in the cylindrical portion 72.

シーリング工程は、図４及び図５に示されるように、第１アルミ板５１とカバー２との境界や、第２アルミ板５２の他の縁部５２ｂと他の補修用アルミ板５０との境界に、シーリング８０を設ける工程である。なお、第１アルミ板５１と第２アルミ板５２とは互いに接触しており、しかも、第１アルミ板５１の縁部５１ａ及び第２アルミ板５２の縁部５２ａの内側には、止水機能を有する仮保持部材６０が設けられているので、第１アルミ板５１と第２アルミ板５２との境界には、シーリングは設けられない。 As shown in FIGS. 4 and 5, the sealing process includes a boundary between the first aluminum plate 51 and the cover 2, and a boundary between the other edge 52 b of the second aluminum plate 52 and the other repair aluminum plate 50. In this step, the sealing 80 is provided. The first aluminum plate 51 and the second aluminum plate 52 are in contact with each other, and the water stop function is provided inside the edge portion 51a of the first aluminum plate 51 and the edge portion 52a of the second aluminum plate 52. Since the temporary holding member 60 having the above is provided, no sealing is provided at the boundary between the first aluminum plate 51 and the second aluminum plate 52.

塗装工程は、補修用アルミ板５０の外面及び固定具７０の外面に塗装によって塗膜９０（図５及び図９を参照）を形成する工程である。 The painting step is a step of forming a coating film 90 (see FIGS. 5 and 9) on the outer surface of the repair aluminum plate 50 and the outer surface of the fixture 70 by painting.

これらの工程を経ることにより、壁１の補修が完了する。 Through these steps, the repair of the wall 1 is completed.

以上に説明したように、本実施形態の壁補修方法では、既設アルミ板３０の浮き上がり部３２を覆うように補修用アルミ板５０が取り付けられ、その補修用アルミ板５０の外面に塗装が施されるという簡単な作業で壁１の外観が改善される。 As described above, in the wall repair method of the present embodiment, the repair aluminum plate 50 is attached so as to cover the raised portion 32 of the existing aluminum plate 30, and the outer surface of the repair aluminum plate 50 is painted. The appearance of the wall 1 is improved by a simple operation.

また、上記実施形態では、準備工程において、補修用アルミ板５０として、既設アルミ板３０の全域を覆う形状を有するものが準備され、位置決め工程において、既設アルミ板３０の外面の全域を覆うように補修用アルミ板５０が位置決めされるので、既設アルミ板３０のうち浮き上がり部３２を含む部位が部分的に補修用アルミ板５０によって覆われる場合（既設アルミ板３０と補修用アルミ板５０との境界が外観に表れる場合）に比べ、壁１の外観が向上する。 Moreover, in the said embodiment, what has the shape which covers the whole region of the existing aluminum plate 30 is prepared as the repair aluminum plate 50 in a preparation process, and it covers so that the whole outer surface of the existing aluminum plate 30 may be covered in a positioning process. Since the repair aluminum plate 50 is positioned, the portion including the raised portion 32 of the existing aluminum plate 30 is partially covered by the repair aluminum plate 50 (the boundary between the existing aluminum plate 30 and the repair aluminum plate 50). The appearance of the wall 1 is improved as compared with the case where the appearance of the wall 1 appears.

また、上記実施形態では、位置決め工程の前に、仮保持部材６０を既設アルミ板３０の外面に取り付ける仮保持部材取付工程を含むので、位置決め工程において補修用アルミ板５０が既設アルミ板３０の外面に仮保持される。よって、補修用アルミ板固定工程での補修用アルミ板５０の固定が容易になる。 Moreover, in the said embodiment, since the temporary holding member attachment process which attaches the temporary holding member 60 to the outer surface of the existing aluminum plate 30 is included before the positioning process, the repair aluminum plate 50 is the outer surface of the existing aluminum plate 30 in the positioning process. Is temporarily held. Therefore, the repair aluminum plate 50 can be easily fixed in the repair aluminum plate fixing step.

ここで、既設アルミ板３０の壁本体１０からの浮き上がりが著しい部位が存在する場合等には、仮保持部材取付工程の前に、当該部位を除去する除去工程を含むことが好ましい。このようにすれば、位置決め工程において既設アルミ板３０の外側に補修用アルミ板５０を位置決めした際の既設アルミ板３０の補修用アルミ板５０への接触が回避されるので、補修用アルミ板５０の位置決めが容易になり、さらに、壁１の外観が向上する。なお、既設アルミ板３０の壁本体１０からの浮き上がりが著しい部位は、前板部３０ｆ及び側板部３０ｓの境界である角部近傍に比較的生じやすい。 Here, when there is a site where the existing aluminum plate 30 is significantly lifted from the wall body 10, it is preferable to include a removal step of removing the site before the temporary holding member attaching step. By doing so, the contact of the existing aluminum plate 30 with the repairing aluminum plate 50 when the repairing aluminum plate 50 is positioned outside the existing aluminum plate 30 in the positioning step is avoided, so the repairing aluminum plate 50 Positioning becomes easier, and the appearance of the wall 1 is further improved. Note that a portion where the existing aluminum plate 30 is significantly lifted from the wall main body 10 is relatively likely to occur in the vicinity of the corner that is the boundary between the front plate portion 30f and the side plate portion 30s.

さらに、上記実施形態では、補修用アルミ板５０として第１アルミ板５１及び第２アルミ板５２を準備し、位置決め工程において、第１アルミ板５１の縁部５１ａの端面と第２アルミ板５２の縁部５２ａの端面とが互いに接触する状態で第１アルミ板５１及び第２アルミ板５２を仮保持部材６０に保持させる。このため、既設アルミ板３０のうち浮き上がり部３２を含む部位の面積が比較的大きな場合や、補修のための作業スペースが限られた状況であっても、効率的に補修を行うことができる。また、第１アルミ板５１の縁部５１ａの端面と第２アルミ板５２の縁部５２ａの端面とが互いに接触しているので、これら縁部５１ａ，５２ａ同士の境界へのシーリングが不要となる。 Furthermore, in the said embodiment, the 1st aluminum plate 51 and the 2nd aluminum plate 52 are prepared as the aluminum plate 50 for repair, and the end surface of the edge part 51a of the 1st aluminum plate 51 and the 2nd aluminum plate 52 are positioned in the positioning process. The first aluminum plate 51 and the second aluminum plate 52 are held by the temporary holding member 60 in a state where the end surfaces of the edge portion 52a are in contact with each other. For this reason, even when the area of the part including the raised portion 32 in the existing aluminum plate 30 is relatively large or the work space for repair is limited, the repair can be performed efficiently. Further, since the end surface of the edge portion 51a of the first aluminum plate 51 and the end surface of the edge portion 52a of the second aluminum plate 52 are in contact with each other, sealing to the boundary between these edge portions 51a and 52a becomes unnecessary. .

また、上記実施形態では、穴形成工程を有し、補修用アルミ板固定工程では、固定具７０としてブラインドリベットが用いられるので、補修用アルミ板５０の既設アルミ板３０への接続強度を確保しながら、壁１の外観を向上させること、すなわち、比較的小さな外形を有する押付部７３を有する固定具７０を選択することができる。 Moreover, in the said embodiment, since it has a hole formation process and a blind rivet is used as the fixing tool 70 in a repair aluminum plate fixing process, the connection strength to the existing aluminum plate 30 of the repair aluminum plate 50 is ensured. However, it is possible to improve the appearance of the wall 1, that is, to select the fixture 70 having the pressing portion 73 having a relatively small outer shape.

なお、今回開示された実施形態は、すべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は、上記した実施形態の説明ではなく特許請求の範囲によって示され、さらに特許請求の範囲と均等の意味及び範囲内でのすべての変更が含まれる。 The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and further includes meanings equivalent to the scope of claims for patent and all modifications within the scope.

例えば、補修用アルミ板固定工程では、固定具７０としては、ブラインドリベットでなく、ねじが用いられてもよい。この場合であっても、既設アルミ板３０の外側に補修用アルミ板５０が取り付けられる。ただし、上記実施形態のように、固定具７０としてブラインドリベットが用いられることにより、固定具７０としてねじが用いられる場合に比べ、壁本体１０に形成する穴の直径を小さくしつつ固定具７０の接続強度を有効に確保することができる。 For example, in the repair aluminum plate fixing step, a screw may be used as the fixture 70 instead of the blind rivet. Even in this case, the repair aluminum plate 50 is attached to the outside of the existing aluminum plate 30. However, since the blind rivet is used as the fixture 70 as in the above-described embodiment, the diameter of the hole formed in the wall body 10 is reduced while the screw 70 is used as the fixture 70. Connection strength can be secured effectively.
