Description

高層の建築物、及びそのメンテナンス方法High-rise building and its maintenance method
　本発明は、高層の建築物のメンテナンス方法に関する。なお、本願における「高層の建築物」の「建築物」の語には、人がその内部に入る用いられ方が本来的な用途として想定されているビルディング等に限らず、人がその内部に入る用いられ方が本来的な用途として想定されていない煙突や、橋梁等も含むものとする。また、本願における「高層の建築物」の「高層の」の語は、その外壁のメンテナンスに技術的な困難が生じる程度の高さ、少なくとも２０ｍ以上の高さを意味するものとする。 The present invention relates to a method for maintaining a high-rise building. The term “building” in “high-rise building” in the present application is not limited to a building or the like that is supposed to be used by a person inside, but a person inside the building. It also includes chimneys and bridges that are not supposed to be used for their intended purpose. In addition, the term “high-rise” in “high-rise building” in the present application means a height at which technical difficulty occurs in the maintenance of the outer wall, that is, a height of at least 20 m.
　高層の建築物に限られないが、高層の建築物においては特に、点検、清掃、塗料の塗りなおし等を含む建築物の外壁等のメンテナンスが困難になりがちである。
　それほど高層でない建築物であれば、ビテイ足場などの足場を場合によっては建築物の外壁に固定しつつ建築物の外壁等に沿って立て、足場の上に乗った作業員が建築物のメンテナンスを行う。しかしながら、この方法は、建築物が高層になると足場の構築の労力が過大になるか、そのような高層の足場の構築自体が不可能となるから実用が難しい。
　そのような事情から、高層の建築物のメンテナンスは一般に、建築物の最上方から吊り下げられたゴンドラに乗った作業員が行う。例えば、ビルディングの場合であれば、屋上に設けたウインチで吊り下げられたゴンドラに乗った作業員がビルディングのメンテナンスを行う。 Although not limited to high-rise buildings, maintenance of outer walls of buildings including inspection, cleaning, repainting, and the like tends to be difficult particularly in high-rise buildings.
If the building is not so high-rise, a scaffolding such as a bite scaffold may be fixed along the outer wall of the building, depending on the case, and a worker on the scaffold may perform maintenance on the building. Do. However, this method is difficult to put into practical use because the construction effort of the scaffold becomes excessive when the building is high-rise, or the construction itself of such a high-rise scaffold becomes impossible.
Under such circumstances, maintenance of high-rise buildings is generally performed by workers on a gondola suspended from the top of the building. For example, in the case of a building, a worker on a gondola suspended by a winch provided on the roof performs maintenance of the building.
　ゴンドラに乗った作業員に建築物のメンテナンスを行わせるのは上述のように一般的であるが、ゴンドラを吊り下げる箇所に制限があったり、揺れにより足場の悪くなりがちなゴンドラに乗っての作業員が行う作業に危険が生じやすい点で課題を残す。 As mentioned above, it is common for workers on a gondola to perform maintenance on the building. The task is left in the point that danger is likely to occur in the work performed by the worker.
　他方、建築物のメンテナンスに、昇降足場を応用することも最近はある。昇降足場は、高いマストと、マストを昇降できる足場とを備えており、足場に乗った作業員がメンテナンス等の作業を行えるようなものとされている。昇降足場は、基本的に建築物の外壁の全面に沿って配することが必要となるビテイ足場と異なり、昇降足場を支えるために必要なだけのマストを立てそれに足場を取付けるだけで使用のための準備が済むのでその使用に際しての労力やコストが小さい。また、昇降足場は、その足場の安定性が宙吊りにされるゴンドラよりも良いから、ゴンドラを用いる場合に比べて、建築物のメンテナンスを行う作業員の安全性の確保が容易となる。
　しかしながら、マストがある程度以上高くなると、マストをその下端で支えるだけではマストの安定性を保つのが難しくなる。他方、マストの上方（本願で「マストの上方」の語は、マストの下端ではない部分を意味する。以下も同じである。）を建築物の適当な部分と固定できればマストの安定性を高めることが可能となるが、一般的に建築物の側壁にはそのような固定が可能な場所がない。また、仮にそのような場所が存在していたとしても、建築物の側壁にマストの上方を固定できる場所が限られているから、マストを立てる場所に制限が生じる、という課題は残ってしまう。また、マストを固定するための何らかの部材を建築物の側壁に後付け的に設けることも考えられるが（実際、ビテイ足場等の足場を、建築物に後付けした第１の金具と、その一端を第１の金具にその他端を足場に固定する第２の金具を用いて、建築物の側壁に接続する技術は実用されている。）、その部材と建築物との接続の強度を必ずしも十分なものとすることが難しく、またそのような部材を建築物の側壁の所望の位置に常に取付けられるわけでもなく、また何よりそのようなことをして建築物を傷つけることを例えば建築物の所有者が嫌う、という事情がある。 On the other hand, recently, lifting scaffolds have been applied to the maintenance of buildings. The lifting / lowering scaffold is provided with a high mast and a scaffold capable of lifting / lowering the mast, so that a worker on the scaffold can perform work such as maintenance. Unlike a scaffold that basically needs to be arranged along the entire outer wall of a building, a lifting scaffold is used only by setting up a mast as much as necessary to support the lifting scaffold. Therefore, the labor and cost for using it are small. In addition, since the scaffolding is better than the gondola in which the scaffolding is suspended in the air, it is easier to ensure the safety of the worker who performs the maintenance of the building compared to the case where the gondola is used.
However, if the mast becomes higher than a certain level, it becomes difficult to maintain the stability of the mast simply by supporting the mast at its lower end. On the other hand, if the upper part of the mast (in the present application, the word “above the mast” means a part that is not the lower end of the mast. The same shall apply hereinafter) can be fixed to an appropriate part of the building to increase the stability of the mast. In general, however, there is no place on the side wall of a building where such fixation is possible. Moreover, even if such a place exists, since the place where the upper part of the mast can be fixed to the side wall of the building is limited, the problem that the place where the mast is raised is limited remains. It is also conceivable to provide a member for fixing the mast on the side wall of the building as a retrofit (actually, the first metal fitting that is retrofitted to the building with a scaffold such as a bite scaffold and one end thereof The technique of connecting to the side wall of the building using the second metal fitting that fixes the other end to the scaffolding to the metal fitting of 1 is practically used.), The strength of the connection between the member and the building is not always sufficient And it is not always possible to attach such a member to the desired location on the side wall of the building, and above all, for example, the owner of the building may hurt the building. I hate it.
　本願発明は、高層の建築物の側壁の所望の部分とマストの上方とを固定できるようにするための技術を提供することをその直接的な目的とし、それにより昇降足場を用いての建築物のメンテナンスを、マストの安定性や、マストの立てる位置についての従来の不具合なしに行えるようにすることをその間接的な目的とする。 The present invention has as its direct object to provide a technique for allowing a desired part of the side wall of a high-rise building to be fixed to the upper part of the mast, whereby a building using a lifting scaffold. It is an indirect purpose to enable maintenance of the mast without the conventional problems with respect to the stability of the mast and the position where the mast stands.
　上述の課題を解決するため、本願発明者は以下の発明を提案する。
　本願発明者が提案するのは、高層の建築物であって、前記建築物の側壁に並行して立てられることが想定されている少なくとも一つのマストと接続するための接続金具が、その側壁の、前記接続金具と接続された前記マストを前記接続金具が安定して支持できるだけの位置に、前記接続金具と接続された前記マストを前記接続金具が安定して支持できるだけの数、取付けられている、建築物、である。
　この建築物は、上述のように、当初から、マストの上方と接続することのできる接続金具をその側壁に備えている。したがって、この建築物によれば、その接続金具を用いることにより、高層の建築物の側壁の所望の部分とマストの上方とを固定できるようになる。また、それにより昇降足場を用いての建築物のメンテナンスを、マストの安定性を保ちながら行えるようになる。更に、マストの上方を固定できる場所が接続金具のある位置に制限されはするものの、接続金具を適当な位置に当初から設けておくことにより、マストの立てる位置についての制限を事実上なきものにできる。
　なお、マストは、建築物の側壁に並行して立てられることが想定されているが、ここで言う「並行」はマストと建築物の側壁とが「平行」である場合も含むが、必ずしも両者が「平行」であることを要しない。マストは、例えば地面に対して垂直に立てられるが、立てられたマストが側壁に、完全ではないものの「沿う」状態となることが想定されていれば、「マストが建築物の側壁に並行して立てられることが想定されている」、という要件が充足されるものとする。例えば、建築物の側面がその縦方向に多少波打っており、マストが地面に対して垂直である場合であっても、「マストが建築物の側壁に並行して立てられることが想定されている」、という要件が充足されるものとする。 In order to solve the above-mentioned problems, the present inventor proposes the following invention.
The inventor proposes a high-rise building, and a connection fitting for connecting to at least one mast that is supposed to stand in parallel with the side wall of the building is provided on the side wall. The masts connected to the connection fittings are attached at positions where the connection fittings can stably support the masts, and the masts connected to the connection fittings are attached in a number sufficient to stably support the masts. , Building.
As described above, this building is provided with a connection fitting on its side wall that can be connected to the upper side of the mast from the beginning. Therefore, according to this building, it becomes possible to fix a desired portion of the side wall of the high-rise building and the upper portion of the mast by using the connection fitting. This also allows maintenance of the building using the lifting scaffold while maintaining the stability of the mast. In addition, although the location where the upper part of the mast can be fixed is limited to the position where the connection bracket is located, by providing the connection bracket from the beginning at an appropriate position, there is virtually no restriction on the position where the mast stands. it can.
It is assumed that the mast is set up in parallel with the side wall of the building, but the term "parallel" here includes the case where the mast and the side wall of the building are "parallel". Does not need to be "parallel". If the mast stands upright, for example, perpendicular to the ground, but it is assumed that the upright mast will be "along", but not perfect, on the side wall, then "mast will run parallel to the side wall of the building. It is assumed that “ For example, even if the side of a building is somewhat wavy in its vertical direction and the mast is perpendicular to the ground, “it is assumed that the mast will stand up against the side wall of the building. The requirement “Yes” is satisfied.
　また、接続金具は、マストと固定できるようになっていればその具体的な構成は問わない。
　例えば、前記接続金具の少なくとも１つの基端が前記側壁に前記建築物の完成時から埋め込まれていても良い。そうすることで、接続金具と建築物の側壁との接続を強固にすることができる。前記接続金具の基端には、前記側壁から前記接続金具が抜けるのを防止するアンカーが設けられていても良い。アンカーの形状は、接続金具の側壁からの抜け止めを実現できるようなものであれば、その詳細を問わない。
　前記接続金具の少なくとも一つの基端は、建築物の柱又は梁に固定されていても良い。建築物の柱又は梁はその強度が高いため、それに接続金具を固定することにより接続金具の建築物の側壁への固定を強固なものにし易くなる。前記接続金具の少なくとも一つの基端は、建築物の柱又は梁に埋め込まれていてもよい。そうすることで、接続金具の側壁への固定をより強固にすることができるようになる。接続金具のすべての基端が、建築物の柱又は梁に固定されていても良く、また、接続金具のすべての基端が、建築物の柱又は梁に埋め込まれていても良い。
　また、後述するように建築物はビルディングである場合がある。そして最近のビルディングは、その側壁が、予め工場等で製造されたパネル（例えば、カーテンウォール工法で用いられるパネル）である場合がある。ビルディングの側壁がパネルで構築されている場合、接続金具の少なくとも一部の基端はパネルに固定されていてもよい。パネルは比較的その強度が高くなるように作られているので、それに接続金具を固定することにより接続金具の建築物の側壁への固定を強固なものにし易くなる。前記接続金具の少なくとも一部の基端は、前記建築物の側壁の外面を構成するパネルに埋め込まれていても良い。そうすることで、接続金具の側壁への固定をより強固にすることができるようになる。接続金具のすべての基端が、パネルに固定されていても良く、また、パネルに埋め込まれていても良い。
　また、建築物がビルディングであり、且つその側壁がパネルで構築されている場合、すべての前記接続金具の基端は、前記建築物の側壁の外面を構成するパネルか、前記建築物の柱又は梁のいずれかに固定されていても良い。また、建築物がビルディングであり、且つその側壁がパネルで構築されている場合、すべての前記接続金具の基端は、前記建築物の側壁の外面を構成するパネルか、前記建築物の柱又は梁のいずれかに埋め込まれていても良い。例えば、パネルが、コンクリート製の板状の本体を備えている場合、前記接続金具の基端は、前記本体に埋め込まれていても良い。
　接続金具の建築物の側壁への埋め込みは、側壁の製造時に行うことができる。例えば、側壁がコンクリート製なのであれば、コンクリートを打設する時点で接続金具の基端を打設されるコンクリートの中に埋め込んでおき、養生後コンクリートが硬化したときには既に接続金具が側壁の内部に埋め込まれているようにすることができる。また、建築物がビルディングであり、その側壁がパネルでできている場合、接続金具は、その基端をパネルの製造時にパネルに埋め込まれるようにすることができる。ビルディングの外壁を構成するためのパネルとしては例えば、ＡＬＣ（Ａｕｔｏｃｌａｖｅｄ　Ｌｉｇｈｔｗｅｉｇｈｔ　Ｃｏｎｃｒｅｔｅ／軽量コンクリート）パネル、ＰＣ（Ｐｒｅｓｔｒｅｓｓｅｄ　Ｃｏｎｃｒｅｔｅ／高強度コンクリート）パネルというコンクリート製のパネルが知られている。ＡＬＣパネルであれば、その厚さが数百ｍｍ程度あるのが一般的なので、コンクリートの打設時にその内部に、接続金具の基端を埋め込んで、その固定を十分に強固なものとすることが可能である。接続金具の基端にアンカーが設けられていれば、パネルと接続金具の結合、ひいては建築物の側壁と接続金具の結合は益々強固になる。
　建築物が例えばマンションその他のビルディングである場合、前記建築物の側壁には少なくとも１つのベランダが設けられている場合がある。その場合、前記接続金具の少なくとも１つは、前記ベランダの少なくとも１つに設けられていても良い。ベランダも接続金具を設けるに適した部分であると言える。
　接続金具がベランダに取付けられる場合、前記接続金具は、前記ベランダの先端面又は下面に設けられていても良い。ベランダの上は一般に、居住者等が歩くスペースとなっているが、その先端面又は下面は居住者等が歩くスペースではないため、そこに接続金具を設けても居住者等に不便をかけることがない。 Moreover, the specific structure is not ask | required if a connection metal fitting can be fixed with a mast.
For example, at least one base end of the connection fitting may be embedded in the side wall from the completion of the building. By doing so, the connection between the connection fitting and the side wall of the building can be strengthened. An anchor that prevents the connection fitting from coming off from the side wall may be provided at the base end of the connection fitting. The shape of the anchor is not particularly limited as long as the anchor can be prevented from coming off from the side wall of the connection fitting.
At least one base end of the connection fitting may be fixed to a pillar or beam of a building. Since the pillar or beam of the building has high strength, fixing the connection fitting to the side wall of the building is facilitated by fixing the connection fitting thereto. At least one base end of the connection fitting may be embedded in a building pillar or beam. By doing so, fixation to the side wall of a connection metal fitting can be strengthened more now. All the base ends of the connection fitting may be fixed to the building column or beam, and all the base ends of the connection fitting may be embedded in the building column or beam.
In addition, as will be described later, the building may be a building. In recent buildings, the side wall may be a panel manufactured in advance in a factory or the like (for example, a panel used in a curtain wall method). When the side wall of the building is constructed of a panel, at least a part of the base end of the connection fitting may be fixed to the panel. Since the panel is made to have a relatively high strength, fixing the connection fitting to the side wall of the building is facilitated by fixing the connection fitting thereto. At least a part of the base end of the connection fitting may be embedded in a panel constituting the outer surface of the side wall of the building. By doing so, fixation to the side wall of a connection metal fitting can be strengthened more now. All the base ends of the connection fittings may be fixed to the panel or may be embedded in the panel.
Further, when the building is a building and the side wall is constructed of a panel, the base ends of all the connection fittings are the panels constituting the outer surface of the side wall of the building, the pillars of the building, It may be fixed to any of the beams. Further, when the building is a building and the side wall is constructed of a panel, the base ends of all the connection fittings are the panels constituting the outer surface of the side wall of the building, the pillars of the building, It may be embedded in any of the beams. For example, when the panel includes a plate-shaped main body made of concrete, the base end of the connection fitting may be embedded in the main body.
The connection fitting can be embedded in the side wall of the building at the time of manufacturing the side wall. For example, if the side wall is made of concrete, the base end of the connection fitting is embedded in the concrete to be placed at the time of placing the concrete, and when the concrete is cured after curing, the connection fitting is already inside the side wall. Can be embedded. Further, when the building is a building and the side wall is made of a panel, the connection fitting can be embedded in the panel at the base end when the panel is manufactured. As panels for constituting the outer wall of a building, for example, concrete panels such as ALC (Autoclaved Lightweight Concrete) panels and PC (Prestressed Concrete / high-strength concrete) panels are known. If it is an ALC panel, its thickness is generally about several hundreds of millimeters. So, when placing concrete, the base end of the connection fitting should be embedded inside to make the fixing sufficiently strong. Is possible. If the anchor is provided at the base end of the connection fitting, the connection between the panel and the connection fitting, and hence the connection between the side wall of the building and the connection fitting becomes stronger.
When the building is, for example, a condominium or other building, at least one veranda may be provided on the side wall of the building. In that case, at least one of the connection fittings may be provided on at least one of the verandas. It can be said that the veranda is also a suitable part for providing the connection fitting.
When the connection fitting is attached to the veranda, the connection fitting may be provided on the front end surface or the lower surface of the veranda. Residents etc. are generally a space for walking on the veranda, but the tip or bottom of the veranda is not a space for residents to walk. There is no.
　接続金具とマストの固定は、接続金具とマストが直接固定されるものでも、また接続金具が他の金具などの他の手段を介してマストと間接的に固定されるものでも良い。また、マストと接続金具の固定は、基本的には着脱自在なものとすべきである。
　前記接続金具は、ナットであってもよい。ナットである前記接続金具は、ネジ切りされたその内周面の一方の開口を前記側壁から露出させるようにして、少なくともその基端側を前記側壁に埋め込まれていてもよい。なお、ナットの他方の開口は存在しなくても（つまり、覆われている状態となっていても）良い。建築物の側壁の、上述した位置に、上述した数のナットを埋め込んでおくだけで、マストを立てる位置についての制限なく、安定した状態でマストを立てられるようになる。 The connection metal fitting and the mast may be fixed directly by fixing the connection metal fitting and the mast, or by fixing the connection metal fitting indirectly to the mast through other means such as other metal fittings. Also, the fixing of the mast and the connecting bracket should be basically detachable.
The connection fitting may be a nut. The connection fitting that is a nut may be embedded in the side wall at least on the base end side so that one opening of the threaded inner peripheral surface is exposed from the side wall. The other opening of the nut may not exist (that is, it may be covered). Just by embedding the above-mentioned number of nuts in the above-mentioned position on the side wall of the building, the mast can be stood in a stable state without any restriction on the position where the mast is to be stood.
　前記接続金具は、前記マストと接続されるときに除去可能とされた、前記接続金具の露出を防ぐカバーによりその表面を覆われていてもよい。
　接続金具が建築物の側壁に設けられていると、建築物の美観が損ねられる可能性がある。また、何らかの原因で舞い上がった何らかの物体が例えば高い位置に位置する接続金具に引っかかる可能性がないとも限らない。上述の如きカバーがあれば、そのような事態を防ぐことが可能となる。例えば、カバーの外観を、建築物の外壁との馴染みの良いものとすることで、建築物の外観を損なう可能性を小さくすることができる。カバーは、建築物の美観を維持する機能と、何らかの物体が接続金具に引っかかる可能性を低減できる機能の一方のみを備えるものであっても良い。
　前記カバーは、前記側壁に対して着脱自在とされていても良い。そのようなカバーであれば、マストと接続金具を接続するときにはカバーを外し、マストと接続金具の接続を解除するときにはカバーを再度取付けることにより、繰り返しカバーを用いることができるようになる。
　また、前記カバーは、それが破壊されることで（不可逆に除去される場合を含む。）その内部にあった前記接続金具が露出するようなものとされていてもよい。例えば、粘土を始めとする粘土状のもの、モルタルを始めとするモルタル状のもの、発泡ウレタン、ウレタン、発泡スチロールなどの樹脂などをカバーとして用いることが可能である。これらの一つをカバーとして用いた場合には、雨水の含浸を防止することにより、雨水による接続金具への影響を低減することが可能となる。 The surface of the connection fitting may be covered with a cover that is removable when connected to the mast and prevents the connection fitting from being exposed.
If the connection fitting is provided on the side wall of the building, the beauty of the building may be impaired. In addition, there is no possibility that any object that has soared for some reason will be caught by a connection fitting located at a high position, for example. If there is a cover as described above, such a situation can be prevented. For example, by making the appearance of the cover familiar with the outer wall of the building, the possibility of impairing the appearance of the building can be reduced. The cover may be provided with only one of the function of maintaining the aesthetics of the building and the function of reducing the possibility of any object being caught by the connection fitting.
The cover may be detachable from the side wall. With such a cover, it is possible to repeatedly use the cover by removing the cover when connecting the mast and the connection fitting, and reattaching the cover when releasing the connection between the mast and the connection fitting.
In addition, the cover may be configured such that the connection fitting that is inside the cover is exposed when the cover is destroyed (including a case where the cover is irreversibly removed). For example, a clay-like material including clay, a mortar-like material including mortar, a resin such as urethane foam, urethane, and polystyrene foam can be used as the cover. When one of these is used as a cover, it is possible to reduce the influence of the rain water on the connection fitting by preventing the rain water from being impregnated.
　接続金具は、上述のように、高層の建築物の側壁の、接続金具と接続されたマストを接続金具が安定して支持できるだけの位置に、前記接続金具と接続されたマストを接続金具が安定して支持できるだけの数、取付けられる。その目的が達成される限りにおいて、接続金具の数は一つでも構わないし、複数であっても構わない。
　例えば、前記接続金具は、前記側壁の外面の少なくとも一つの縦方向の線上（典型的には垂直の線上）に少なくとも２つ設けられていても良い。そのように接続金具が配置されていれば、１本のマストを側壁に固定する場合において、そのマストの下端以外に、そのマストの上方の２箇所を接続金具と固定することができるようになるので、マストの安定性を増すに有用である。 As described above, the connection bracket is connected to the mast connected to the connection bracket in a position where the connection bracket can stably support the mast connected to the connection bracket on the side wall of the high-rise building. As many as can be supported. As long as the object is achieved, the number of connection fittings may be one or plural.
For example, at least two of the connection fittings may be provided on at least one vertical line (typically a vertical line) on the outer surface of the side wall. If the connection fitting is arranged in such a manner, when one mast is fixed to the side wall, two places above the mast can be fixed to the connection fitting other than the lower end of the mast. So it is useful for increasing the stability of the mast.
　本願発明による建築物は、オフィス用途の、或いは居住用のマンションであるビルディングであっても良い。もっとも、建築物は、人がその内部に入る用いられ方が本来的な用途として想定されていない煙突や、橋梁等の所謂構築物と呼ばれる建築物であっても構わない。 The building according to the present invention may be a building for office use or a residential apartment. Of course, the building may be a so-called structure such as a chimney or a bridge that is not supposed to be used as a primary use by humans.
　接続金具は建築物の側壁に設けられる。接続金具はマストと固定できるようになっている必要があるから、上述の、或いは後述するカバーがない状態では外部に少なくともその一部が露出する状態となる。
　前記接続金具の少なくとも一つは、前記側壁の外面に設けられた凹部の内部に取付けられており、前記接続金具は、前記側壁の略面一の面である外面から露出しないようになっていてもよい。建築物の美観を維持する機能、或いは何らかの物体が接続金具に引っかかる可能性を低減できる機能を発揮させるための手段として、カバーを用いることができることを既に述べた。同様の機能を、接続金具を凹部の中に設けることにより得られることがある。すべての接続金具が凹部の中にあることも当然に許容される。
　上述のように本願の建築物は、ビルディングである場合があり、ビルディングの側壁はパネルにて構成されている場合がある。その場合、接続金具がその内部に設けられる凹部はパネルに設けられていても良い。パネルが例えばＡＬＣパネル、ＰＣパネルなどのコンクリート製のパネルであれば、その厚さは上述したように数百ｍｍあるので、凹部を作り、且つその凹部の底に接続金具の基端を固定し、或いは接続金具の基端を埋め込んだとしても、パネルと接続金具の結合を十分に強固なものとするに問題はない。
　凹部は建築物がビルディングである場合、ビルディングの側壁の外面を構成するパネルの隙間に設けられていても良い。つまり、前記接続金具の少なくとも一つは、前記側壁の外面に設けられた凹部の内部に取付けられており、前記接続金具は、前記側壁の前記外面の外側の略面一の面である前記外面の表面から露出しないようになっている場合において、前記凹部は、ビルディングの側壁の外面を構成するパネルの隙間であっても良い。
　いずれの場合においても前記凹部には、前記接続金具の露出を隠すカバーが設けられていても良い。つまり、パネルの凹部にカバーを設けることもできる。カバーの構成、機能については既に述べた通りである。
　例えば、パネルがコンクリート製の本体を備えている場合、前記本体の外面には凹部が設けられているとともに、前記接続金具は、前記凹部の内部に取付けられ、前記側壁の略面一の面である外面から露出しないようになっていても良い。そしてパネルの本体に設けられた前記凹部には、前記接続金具の露出を隠すカバーが設けられていても良い。前記カバーは、前記凹部の開口を覆う板であっても良い。板は凹部の開口に対して着脱自在であってもよい。それにより、繰り返しカバーを用いることができるようになる。カバーの外観を建築物の外壁との馴染みの良いものとするために、板であるカバーの外側に、建築物の側壁の表面に配された素材（例えばタイル）を配しておくことも可能である。前記本体の少なくとも外面は板で被覆されていても良い。この場合、前記板のうち前記凹部に対応する部分は、他の部分から除去可能とされており、その除去可能な部分が前記カバーとして機能するようになっていても良い。この板は、例えば金属板であり、本体の背面を除く、外面、上下面、及び左右面を覆うものとなっていても良い。
　前記カバーは、前記凹部に充填される充填材であってもよい。この場合のカバーは、それが破壊されることでその内部にあった前記接続金具が露出するようなものとされていてもよい。例えば、粘土を始めとする粘土状のもの、モルタルを始めとするモルタル状のもの、発泡ウレタン、ウレタン、発泡スチロールなどの樹脂などを充填材であるカバーとして凹部に充填することができる。
　この場合、前記凹部は、その内部で、前記接続金具と、前記接続金具と前記マストとを繋ぐ連結金具との、前記接続金具側の接続を行えるような形状、大きさになっていても良い。凹部の中の接続金具が連結金具の一方と接続され、マストが連結金具の他方と接続されることにより、接続金具とマストは固定的に接続される。ここで、凹部を、その内部で、接続金具と、接続金具とマストとを繋ぐ連結金具との、接続金具側の接続を行えるような形状、大きさ（言い換えれば、そのような接続を行えるような空間的な余裕のある形状、大きさ）にすることにより、接続金具と連結金具の接続を行えるのみならず、接続金具と連結金具の接続の解除を行うことによりマストと接続金具の固定を解除した後において凹部の内部に残る接続金具を、再利用できることになる。かかる再利用を行うに際して、凹部に対して再度カバーを設けることも可能である。 The connection fitting is provided on the side wall of the building. Since the connection fitting needs to be able to be fixed to the mast, at least a part of the connection fitting is exposed to the outside in the absence of the cover described above or described later.
At least one of the connection fittings is attached to the inside of a recess provided on the outer surface of the side wall, and the connection fitting is not exposed from the outer surface which is substantially flush with the side wall. Also good. It has already been mentioned that a cover can be used as a means for exhibiting the function of maintaining the aesthetics of a building or the function of reducing the possibility that any object will be caught by the connection fitting. A similar function may be obtained by providing the connection fitting in the recess. Of course, it is also acceptable for all the fittings to be in the recesses.
As described above, the building of the present application may be a building, and the side wall of the building may be constituted by panels. In that case, the recess in which the connection fitting is provided may be provided in the panel. If the panel is a concrete panel such as an ALC panel or PC panel, the thickness is several hundred mm as described above. Therefore, a recess is formed, and the base end of the connection fitting is fixed to the bottom of the recess. Alternatively, even if the base end of the connection fitting is embedded, there is no problem in sufficiently strengthening the coupling between the panel and the connection fitting.
When the building is a building, the recess may be provided in a gap between panels constituting the outer surface of the side wall of the building. That is, at least one of the connection fittings is attached to the inside of a recess provided on the outer surface of the side wall, and the connection fitting is the outer surface that is substantially flush with the outside of the outer surface of the side wall. In the case where the surface is not exposed from the surface, the concave portion may be a gap between panels constituting the outer surface of the side wall of the building.
In any case, the concave portion may be provided with a cover that hides the exposure of the connection fitting. That is, a cover can be provided in the recess of the panel. The structure and function of the cover are as described above.
For example, when the panel includes a main body made of concrete, a concave portion is provided on the outer surface of the main body, and the connection fitting is attached inside the concave portion, and is substantially flush with the side wall. It may not be exposed from a certain outer surface. And the cover which hides the exposure of the said connection metal fitting may be provided in the said recessed part provided in the main body of the panel. The cover may be a plate that covers the opening of the recess. The plate may be detachable with respect to the opening of the recess. Thereby, the cover can be used repeatedly. In order to make the appearance of the cover familiar with the outer wall of the building, it is also possible to arrange the material (for example, tiles) arranged on the surface of the side wall of the building on the outside of the cover, which is a board It is. At least the outer surface of the main body may be covered with a plate. In this case, a portion of the plate that corresponds to the concave portion can be removed from other portions, and the removable portion may function as the cover. This plate is, for example, a metal plate, and may cover the outer surface, the upper and lower surfaces, and the left and right surfaces excluding the back surface of the main body.
The cover may be a filler that fills the recess. The cover in this case may be configured such that the connection fitting that is inside the cover is exposed when the cover is broken. For example, a clay-like thing including clay, a mortar-like thing such as mortar, a resin such as urethane foam, urethane, and polystyrene foam can be filled in the recess as a cover that is a filler.
In this case, the concave portion may have a shape and a size such that the connection fitting and the connection fitting connecting the connection fitting and the mast can be connected on the connection fitting side. . The connection fitting in the recess is connected to one of the connection fittings, and the mast is connected to the other of the connection fittings, whereby the connection fitting and the mast are fixedly connected. Here, the concave portion has a shape and a size (in other words, so that such a connection can be performed) in which the connection metal fitting and the connection metal fitting connecting the connection metal fitting and the mast can be connected on the connection metal fitting side. In addition to being able to connect the connection bracket to the connection bracket, the mast and the connection bracket can be fixed by releasing the connection between the connection bracket and the connection bracket. The connection fitting remaining inside the recess after being released can be reused. When performing such reuse, it is also possible to provide a cover for the concave portion again.
　本願発明者は、また、ビルディングの側壁の外面を構成するパネルであって、その外面に接続金具の基端が固定されており、そのパネルをビルディングである高層の建築物の予定された位置に取付けることで、前記建築物の側壁に並行して立てられることが想定されている少なくとも一つのマストと接続するための接続金具が、その側壁の、前記接続金具と接続された前記マストを前記接続金具が安定して支持できるだけの位置に、前記接続金具と接続された前記マストを前記接続金具が安定して支持できるだけの数、取付けられた建築物を建築することができるようになっている、パネルをも本願発明の一形態として提案する。このパネルにも凹部を設けることができ、接続金具が凹部の中に設けられていて良いのは当然である。また、凹部の有無を問わず、このパネルにも既に説明した、或いは後述するのと同様のカバーが設けられていても良い。
　凹部がパネルに設けられている場合であっても、前記凹部は、その内部で、前記接続金具と、前記接続金具と前記マストとを繋ぐ連結金具との、前記接続金具側の接続を行えるような形状、大きさになっていても良い。これによる利点は、凹部がパネルに設けられていない場合と同様である。 The inventor of the present invention is also a panel constituting the outer surface of the side wall of the building, and the base end of the connection fitting is fixed to the outer surface, and the panel is placed at a predetermined position of the high-rise building as the building. A connection fitting for connecting to at least one mast that is supposed to be stood in parallel with the side wall of the building by attaching the mast connected to the connection fitting on the side wall. In a position where the metal fitting can be stably supported, the number of the masts connected to the connection metal fitting can be stably supported by the connection metal fitting so that the attached building can be built. A panel is also proposed as an embodiment of the present invention. This panel can also be provided with a recess, and it is natural that the connection fitting may be provided in the recess. Moreover, the cover similar to what was already demonstrated or mentioned later may be provided also in this panel irrespective of the presence or absence of a recessed part.
Even when the recess is provided in the panel, the recess can connect the connection fitting and the connection fitting connecting the connection fitting and the mast on the connection fitting side. It may be any shape or size. The advantage by this is the same as the case where the recessed part is not provided in the panel.
　本願発明者は、また、高層の建築物のメンテナンス方法をも提供する。
　その方法は、前記建築物の側壁に並行して立てられることが想定されている少なくとも一つのマストと接続するための接続金具が、その側壁の、前記接続金具と接続された前記マストを前記接続金具が安定して支持できるだけの位置に、前記接続金具と接続された前記マストを前記接続金具が安定して支持できるだけの数、取付けられている高層の建築物の前記接続金具のうちの少なくとも１つに、少なくとも接続した状態で、その下端を固定された少なくとも１つのマストを前記建築物の側壁に並行して立て、前記マストを昇降することのできる足場を取付け、前記足場を前記マストに沿って昇降させるとともに、前記足場に乗った作業員に前記建築物のメンテナンス作業を行わせる、メンテナンス方法である。
　この方法によれば、昇降足場を用いての建築物のメンテナンスを、マストの安定性を保ちながら行えるようになるとともに、マストの立てる位置についての制限を事実上ない状態にできる。 The present inventor also provides a maintenance method for a high-rise building.
In the method, a connection fitting for connecting to at least one mast that is supposed to stand in parallel with a side wall of the building is connected to the mast of the side wall connected to the connection fitting.

≪第１実施形態≫
　図１に、第１実施形態における建築物１００を示す。
　建築物１００は、ビルディングである。建築物１００たるビルディングは、例えば、オフィスビル、マンションである。建築物１００は、地盤５００に立っている。後述する接続金具を備える点を除き、建築物１００の構成はごく一般的なものである。図１には、出入り口、窓等の記載がないが、当然に建築物１００は通常の建築物が、或いは通常のビルディングが要求される機能を充足させるための構成を備えている。
　建築物１００は高層である。建築物１００は、その高さが２０ｍ以上であり、そのメンテナンスに困難が生じやすい程度の高さである。建築物１００の高さは例えば数百ｍ以上であってもよい。 << First Embodiment >>
FIG. 1 shows a building 100 in the first embodiment.
The building 100 is a building. The building which is the building 100 is, for example, an office building or a condominium. The building 100 stands on the ground 500. The structure of the building 100 is very general except that it includes a connection fitting described later. Although FIG. 1 does not show entrances and exits, windows, and the like, naturally, the building 100 has a structure for satisfying the functions required for a normal building or a normal building.
The building 100 is a high-rise building. The building 100 has a height of 20 m or more, and is high enough to cause difficulty in maintenance. The height of the building 100 may be several hundred meters or more, for example.
　接続金具１１０は、金属製であり、後述するように、これも後述するマストの上方（マストの下端以外の部分）と接続可能となっている。また、接続金具１１０は、マストの上方と接続されたときにマストを安定して支持できるだけの強度を備えている。後述のように、マストは、昇降足場の一部をなすものである。
　建築物１００の側壁１０１には、少なくとも一つの接続金具１１０が設けられている。図１の例では複数の、より詳細には７つの接続金具１１０が建築物１００の側壁１０１に設けられている。なお、図１では理解の容易のために、接続金具１１０を大きめに記載している。
　接続金具１１０は建築物１００の側壁１０１の所定の位置に設けられている。接続金具１１０が設けられる側壁１０１における位置は、追って立てられるマストを、接続金具１１０と固定することができるような位置である。
　つまり、接続金具１１０は、接続金具１１０と接続されたマストを接続金具１１０が安定して支持できるだけの位置に、接続金具１１０と接続されたマストを接続金具１１０が安定して支持できるだけの数、側壁１０１に取付けられる。
　建築物１００が略直方体形状のビルディングである場合には側壁１０１は４面存在する。その場合接続金具１１０は、側壁１０１の１面にのみ存在する場合もあるし、側壁１０１の２面又は３面に存在する場合もあるし、或いはすべての側壁１０１に存在する場合もある。
　また、接続金具１１０は、側壁１０１の全体に存在している場合もあるし、側壁１０１の一部の範囲にのみ存在している場合がある。
　また、接続金具１１０が側壁１０１のある範囲に存在する場合、接続金具１１０は接続金具１１０が存在する範囲の全面に一様に配されている場合もあるし、ある範囲では密に、ある範囲では疎に配されている場合もありうる。 The connection fitting 110 is made of metal and can be connected to the upper portion of the mast (a portion other than the lower end of the mast), which will be described later, as will be described later. In addition, the connection fitting 110 has a strength sufficient to stably support the mast when connected to the upper side of the mast. As will be described later, the mast forms a part of the lifting scaffold.
At least one connection fitting 110 is provided on the side wall 101 of the building 100. In the example of FIG. 1, a plurality of, more specifically, seven connection fittings 110 are provided on the side wall 101 of the building 100. In FIG. 1, the connecting metal fitting 110 is shown in a larger size for easy understanding.
The connection fitting 110 is provided at a predetermined position on the side wall 101 of the building 100. The position on the side wall 101 where the connection fitting 110 is provided is such a position that a mast that can be stood up can be fixed to the connection fitting 110.
In other words, the number of connecting fittings 110 is such that the connecting fitting 110 can stably support the mast connected to the connecting fitting 110, and the number capable of stably supporting the mast connected to the connecting fitting 110. Attached to the side wall 101.
When the building 100 is a substantially rectangular parallelepiped building, there are four side walls 101. In that case, the connection fitting 110 may exist only on one surface of the side wall 101, may exist on two or three surfaces of the side wall 101, or may exist on all the side walls 101.
Further, the connection fitting 110 may exist on the entire side wall 101 or may exist only on a part of the side wall 101.
Further, when the connection fitting 110 exists in a certain range of the side wall 101, the connection fitting 110 may be uniformly arranged on the entire surface of the range where the connection fitting 110 exists, or in a certain range, a certain range. Then, it may be distributed sparsely.
　接続金具１１０は、例えば、図１２（Ａ）に示したようにして側壁１０１に取付けられている。接続金具１１０の基端には、アンカー１１０Ａが設けられている。
　接続金具１１０のアンカー１１０Ａは、側壁１０１を製造する段階で、例えば、側壁１０１を形成するためにコンクリートを打設する前段階で後に側壁１０１が位置することとなる空間に位置させられる。その状態でコンクリートを打設し、コンクリートを硬化させることで、接続金具１１０のアンカー１１０Ａは側壁１０１の中に埋め込まれた状態となる。アンカー１１０Ａは例えば、傘が開いたような形状をしている。この形状は、アンカー１１０Ａが側壁１０１から抜け落ちるのを防止する。アンカー１１０Ａの存在により、接続金具１１０は、強固に側壁１０１に固定される。なお、アンカー１１０Ａの形状は必ずしも図示したような傘型である必要はなく、アンカー１１０Ａが側壁１０１から抜け落ちるのを防止できる形状であれば良い。アンカー１１０Ａの形状は、公知のものを採用し得る。アンカー１１０Ａは、建築物１００の柱又は梁を含む側壁１０１に埋め込まれる。
　建築物１００がビルディングである場合、その側壁１０１は、パネルの集合により構成されている場合がある。パネルは例えば、ＡＬＣパネル又はＰＣパネルである。パネルは例えば矩形の板状であり、一般的には隣接するもの同士の縦横の長さが揃っている。パネルは、縦横に配列され、側壁１０１を構成する。接続金具１１０のアンカー１１０Ａは、パネルの製造時にパネルに埋め込むことができる。パネルが、コンクリートにより形成されている場合には、側壁１０１の製造時にアンカー１１０Ａを側壁１０１に埋め込む上述の方法と同様の方法で、パネルの製造時にアンカー１１０Ａを埋め込むことができる。パネルの厚さは、そのようなアンカー１１０Ａの埋め込みを行ってもなおパネルの強度、及びパネルとアンカー１１０Ａの結合の強度が十分な程度にし、例えば３００ｍｍ程度とする。建築物１００の側壁１０１がパネルの集合により構成されている場合、すべてのパネルに接続金具１１０が取付けられている必要はないし、また一つのパネルに２つ以上の接続金具１１０が取付けられている場合もあり得る。パネルは建築物１００の建築現場ではなく一般的に工場で製造されるものであるが、工場でパネルを製造する段階で、多数のパネルを配列して建築物１００の側壁１０１を構築した際に、最終的に必要な部分に接続金具１１０が位置するように設計しておけば良い。
　なお、側壁１０１或いはパネルへの接続金具１１０の固定は、必ずしも側壁１０１或いはパネルにそのアンカー１１０Ａを埋め込むことによらなくても良い。例えば、図１２（Ｂ）に示したように、接続金具１１０は、その基端に板状のベース１１０Ｂを備えておりそのベースを側壁１０１或いはパネルの表面に当接させた上で、ベース１１０Ｂに設けられた図示を省略の孔を貫通させたビス１１０Ｃを側壁１０１或いはパネルに打込んで螺合させることにより、側壁１０１或いはパネルへの接続金具１１０の固定を行っても良い。
　なお、側壁１０１或いはパネルへの接続金具１１０の固定は、すべての接続金具１１０について同一である必要はない。
　この実施形態では、建築物１００はビルディングであり、その側壁１０１はパネルでできている。そして、必ずしもこの限りではないが、すべての接続金具１１０はアンカー１１０Ａを備えており、すべての接続金具１１０のアンカー１１０Ａは、パネルか、側壁１０１の一部である柱又は梁に埋め込まれている。 For example, the connection fitting 110 is attached to the side wall 101 as shown in FIG. An anchor 110 </ b> A is provided at the proximal end of the connection fitting 110.
The anchor 110 </ b> A of the connection fitting 110 is positioned in a space in which the side wall 101 is positioned after the side wall 101 is manufactured, for example, before the concrete is placed in order to form the side wall 101. In this state, concrete is placed and the concrete is hardened, whereby the anchor 110 </ b> A of the connection fitting 110 is embedded in the side wall 101. The anchor 110A has, for example, a shape in which an umbrella is opened. This shape prevents the anchor 110A from falling off the side wall 101. Due to the presence of the anchor 110 </ b> A, the connection fitting 110 is firmly fixed to the side wall 101. The shape of the anchor 110 </ b> A is not necessarily an umbrella shape as illustrated, and may be any shape that can prevent the anchor 110 </ b> A from falling off the side wall 101. A well-known thing can be employ | adopted for the shape of the anchor 110A. The anchor 110 </ b> A is embedded in the side wall 101 including the pillar or beam of the building 100.
When the building 100 is a building, the side wall 101 may be constituted by a set of panels. The panel is, for example, an ALC panel or a PC panel. The panel is, for example, a rectangular plate, and generally the lengths and widths of adjacent ones are aligned. The panels are arranged vertically and horizontally and constitute the side wall 101. The anchor 110A of the connection fitting 110 can be embedded in the panel when the panel is manufactured. When the panel is made of concrete, the anchor 110A can be embedded at the time of manufacturing the panel by the same method as described above for embedding the anchor 110A in the side wall 101 when the side wall 101 is manufactured. The thickness of the panel is set such that the strength of the panel and the strength of the coupling between the panel and the anchor 110A are still sufficient even when such anchor 110A is embedded, for example, about 300 mm. When the side wall 101 of the building 100 is constituted by a set of panels, it is not necessary that the connection fittings 110 be attached to all the panels, and two or more connection fittings 110 are attached to one panel. There may be cases. The panel is generally manufactured at a factory, not at the construction site of the building 100, but when the panel is manufactured at the factory, when the side wall 101 of the building 100 is constructed by arranging a large number of panels. What is necessary is just to design so that the connection metal fitting 110 is located in a finally required part.
Note that the connection fitting 110 may not be fixed to the side wall 101 or the panel by embedding the anchor 110A in the side wall 101 or the panel. For example, as shown in FIG. 12B, the connection fitting 110 is provided with a plate-like base 110B at its base end, and the base 110B is brought into contact with the side wall 101 or the surface of the panel. The connection fitting 110 may be fixed to the side wall 101 or the panel by driving and screwing the screw 110C, which is provided in FIG.
The fixing of the connection fitting 110 to the side wall 101 or the panel does not have to be the same for all the connection fittings 110.
In this embodiment, the building 100 is a building and its side wall 101 is made of a panel. Although not necessarily limited to this, all the connection fittings 110 are provided with anchors 110A, and the anchors 110A of all the connection fittings 110 are embedded in a panel or a column or beam that is a part of the side wall 101. .
　一の側壁１０１の正面図を図２に示す。図２には、接続金具１１０が側壁１０１に取付けられる幾つかのパターンをまとめて示している。
　この例で示された側壁１０１への接続金具１１０の取付け方のパターンは、Ａ～Ｄの４つである。各パターンで示された接続金具１１０のうち、側壁１０１の同一の縦方向の線上に並ぶ接続金具１１０はそれぞれ、一本のマストを支えるのに用いられる。Ａ～Ｄのパターンとも側壁１０１の縦方向の線（典型的には垂直な線）に沿って配列された、或いは垂直方向に配列された、複数の接続金具１１０が含まれている。各パターンに含まれた一連の接続金具１１０により、マストは垂直ないしそれに近い状態で、建築物１００の側壁１０１に並行した状態で支えられることになる。
　まずＡのパターンについて説明する。Ａのパターンでは、垂直方向では等間隔となるようにして、接続金具１１０が側壁１０１の高さ方向の略全体に亘って、一列に配列されている。各接続金具１１０は、マストを接続するために使用可能であるが、マストの接続時に、すべての接続金具１１０がマストと接続されるとは限らない。なお、この点は以下のＢ～Ｄでも同様である。
　次にＢのパターンについて説明する。Ｂのパターンでは、垂直方向での間隔が不規則になるようにして、接続金具１１０が側壁１０１の高さ方向の略全体に亘って、一列に配列されている。
　次にＣのパターンについて説明する。Ｃのパターンでは、垂直方向での間隔が等間隔になるようにして、接続金具１１０が側壁１０１の高さ方向の一部に、一列に配列されている。このように接続金具１１０は側壁１０１の縦方向においても一様に存在する必要はない。
　次にＤのパターンについて説明する。Ｄのパターンでは、垂直方向では等間隔となるようにして、接続金具１１０が側壁１０１の高さ方向の略全体に亘って二列に配列されている。この例では、横並びの２つの接続金具１１０を用いて、マストの同じ高さを支持することで、マストの固定の強度をあげることができる。
　また、パターンＣとパターンＤの間には接続金具１１０が存在しない部分がある。このように、接続金具１１０は、横方向においても一様に存在する必要はない。 A front view of one side wall 101 is shown in FIG. FIG. 2 collectively shows several patterns in which the connection fitting 110 is attached to the side wall 101.
There are four patterns A to D for attaching the connection fitting 110 to the side wall 101 shown in this example. Of the connection fittings 110 shown in each pattern, each of the connection fittings 110 arranged on the same vertical line of the side wall 101 is used to support one mast. Each of the patterns A to D includes a plurality of connection fittings 110 arranged along a vertical line (typically a vertical line) of the sidewall 101 or arranged in the vertical direction. The mast is supported in a state of being parallel to the side wall 101 of the building 100 in a vertical state or a state close thereto by a series of connection fittings 110 included in each pattern.
First, the pattern A will be described. In the pattern A, the connection fittings 110 are arranged in a line over substantially the entire height of the side wall 101 so as to be equally spaced in the vertical direction. Each connection fitting 110 can be used to connect a mast, but not all the connection fittings 110 are connected to the mast when the mast is connected. This also applies to B to D below.
Next, the pattern B will be described. In the pattern B, the connection fittings 110 are arranged in a line over substantially the entire height of the side wall 101 such that the intervals in the vertical direction are irregular.
Next, the pattern C will be described. In the pattern C, the connection fittings 110 are arranged in a line in a part of the side wall 101 in the height direction so that the intervals in the vertical direction are equal. Thus, the connection fitting 110 does not need to exist even in the longitudinal direction of the side wall 101.
Next, the pattern D will be described. In the pattern D, the connection fittings 110 are arranged in two rows over substantially the entire height of the side wall 101 so as to be equally spaced in the vertical direction. In this example, the strength of fixing the mast can be increased by supporting the same height of the mast using the two connecting fittings 110 arranged side by side.
In addition, there is a portion where the connection fitting 110 does not exist between the pattern C and the pattern D. Thus, the connection fitting 110 does not need to exist uniformly also in the horizontal direction.
　接続金具１１０でマストを固定して、マストを垂直ないしそれに近い状態で、建築物１００の側壁１０１に並行した状態に立てた状態を図３に示す。
　図３の側面図に示したように、マスト２００は接続金具１１０と、連結金具３００を介して接続することが可能である。
　接続金具１１０と、連結金具３００の構造の詳細と、接続の方法とを、図４の斜視図を用いて説明する。なお、連結金具３００は、この実施形態では金属製である。また、接続金具１１０と連結金具３００とは、それらを互いに着脱自在に接続できるようになっていれば足りる。つまり、以下に説明する、接続金具１１０と連結金具３００の構成は、あり得る構成の一例に過ぎない。 FIG. 3 shows a state where the mast is fixed by the connecting metal fitting 110 and the mast is set in a state of being parallel to the side wall 101 of the building 100 in the vertical state or close to it.
As shown in the side view of FIG. 3, the mast 200 can be connected to the connection fitting 110 via the connection fitting 300.
Details of the structure of the connection fitting 110 and the connection fitting 300 and the connection method will be described with reference to the perspective view of FIG. Note that the connecting metal fitting 300 is made of metal in this embodiment. Moreover, the connection metal fitting 110 and the connection metal fitting 300 are sufficient if they can be detachably connected to each other. That is, the configurations of the connection fitting 110 and the connection fitting 300 described below are merely examples of possible configurations.
　接続金具１１０は側壁１０１から垂直に伸びる接続本体部１１１と、これには限られないが接続本体部１１１を上方に折り曲げてなる接続係止部１１２とからなる。接続本体部１１１の基端（図４の左奥）側は、適当な方法で側壁１０１に固定されている。例えば、接続本体部１１１の基端には板状のベースが設けられており、そのベースに穿たれた孔を貫通したボルトを側壁１０１に螺合させることにより、或いは接続本体部１１１の基端は側壁の中に埋め込まれて抜け出さない形状となっているアンカーを備えており、そのアンカーを側壁１０１中に固定することにより、接続本体部１１１の基端側は側壁１０１に固定されている。
　他方、連結金具３００は、棒状の連結本体部３０１を備えている。連結本体部３０１は、図示と詳述を省略するが、適当な構造により、その基端（図４の右手前）側を、マスト２００と固定できるようになっている。連結本体部３０１の先端側には、把持部３０２が設けられている。把持部３０２は、連結本体部３０１と接続金具１１０の固定をなすものである。把持部３０２は下が開いたコの字型をしている。また、把持部３０２の両先端には図示を省略のネジ孔が空けられている。把持部３０２の下端には、板状の部材である蓋３０３が取付けられるようになっている。蓋３０３は把持部３０２の下側の開口を塞ぐものである。把持部３０２の両先端部分には、図示を省略の孔が穿たれており、蓋３０３の両側のその孔に対応する位置には、これも図示を省略のネジ穴が設けられている。２つの把持部３０２の先端部分に設けられた孔を貫通させたボルト３０４の先端を、蓋３０３の両側のネジ穴に螺合させることによって、蓋３０３は把持部３０２にしっかりと固定される。そのとき、蓋３０３でその下側を、把持部３０２の内側面でその上側と左右両側とを囲まれた矩形の孔ができる。その矩形の孔の断面形状と大きさは、接続金具１１０の接続本体部１１１の断面形状に対応したものとなっている。つまり、２つの把持部３０２で接続金具１１０の接続本体部１１１を跨いだ状態で、把持部３０２に蓋３０３を固定すると、接続本体部１１１の先端の太さが接続係止部１１２を備えているから太くなっていることもあり、把持部３０２と蓋３０３に囲まれた上述の矩形の孔から接続本体部１１１が抜けなくなる。
　つまり、上述の矩形の孔（の周囲）が接続係止部１１２と係止し合うことにより、接続金具１１０と連結金具３００をしっかり固定することができる。 The connection fitting 110 includes a connection main body 111 extending vertically from the side wall 101 and a connection locking portion 112 formed by bending the connection main body 111 upward, although not limited thereto. The base end (left back in FIG. 4) side of the connection main body 111 is fixed to the side wall 101 by an appropriate method. For example, the base end of the connection main body 111 is provided with a plate-like base, and a bolt penetrating a hole drilled in the base is screwed into the side wall 101 or the base end of the connection main body 111. Is provided with an anchor that is embedded in the side wall and does not come out, and by fixing the anchor in the side wall 101, the base end side of the connection main body 111 is fixed to the side wall 101.
On the other hand, the connection fitting 300 includes a rod-like connection main body 301. Although the illustration and detailed description of the connection main body 301 are omitted, the base end (right front side in FIG. 4) side can be fixed to the mast 200 by an appropriate structure. A grip portion 302 is provided on the distal end side of the connection main body portion 301. The grip portion 302 fixes the connection main body portion 301 and the connection fitting 110. The grip portion 302 has a U-shape with an open bottom. Further, screw holes (not shown) are formed at both ends of the grip portion 302. A lid 303, which is a plate-like member, is attached to the lower end of the grip portion 302. The lid 303 closes the lower opening of the grip portion 302. Both end portions of the grip portion 302 are provided with holes (not shown), and screw holes (not shown) are also provided at positions corresponding to the holes on both sides of the lid 303. The lid 303 is firmly fixed to the gripping portion 302 by screwing the tip ends of the bolts 304 penetrating the holes provided at the tip portions of the two gripping portions 302 into the screw holes on both sides of the lid 303. At that time, a rectangular hole is formed with the lid 303 surrounded by the lower side and the inner side surface of the gripper 302 surrounded by the upper side and the left and right sides. The cross-sectional shape and size of the rectangular hole correspond to the cross-sectional shape of the connection main body 111 of the connection fitting 110. That is, when the lid 303 is fixed to the gripping portion 302 with the two gripping portions 302 straddling the connection main body portion 111 of the connection fitting 110, the thickness of the tip of the connection main body portion 111 includes the connection locking portion 112. Therefore, the connection main body 111 cannot be removed from the rectangular hole surrounded by the grip portion 302 and the lid 303.
In other words, the above-described rectangular hole (around) engages with the connection locking portion 112, so that the connection fitting 110 and the connection fitting 300 can be firmly fixed.
　次いで、接続金具１１０を備えた建築物１００のメンテナンス方法について説明する。
　メンテナンスには昇降足場を用いる。昇降足場は周知であり、当業者において特に説明を要することはないためその詳細の説明を省略するが、昇降足場は、マストとそれに沿って昇降を自由に行えるようにされた足場とを備えている。足場は駆動装置を含んでいる。駆動装置は、マストに対して昇降するための動力を発生させるものであるとともに、マストに対して任意の高さで固定することができるものとなっている。 Next, a maintenance method for the building 100 including the connection fitting 110 will be described.
A lifting scaffold is used for maintenance. Lifting scaffolds are well known and need not be described in detail by those skilled in the art, so detailed description thereof will be omitted. However, the lifting scaffolds include a mast and a scaffold that can freely move up and down along the mast. Yes. The scaffold includes a drive. The drive device generates power for moving up and down with respect to the mast and can be fixed at an arbitrary height with respect to the mast.
　メンテナンスを行うためには、メンテナンスのための作業を行うために足場が必要となる部分に足場を位置させられるようにするために、足場を位置させるに適当な位置にマスト２００（図３、及び図１３を参照。）を立設する。
　この実施形態では、建築物１００の各側壁１０１の幅方向の両端付近に、マスト２００を立てることとしている。ある側壁１０１の幅方向の両端付近に立てられたマスト２００は、その側壁１０１の横幅に略相当する足場２１０の両端付近をそれぞれ支持するものとなっている。ある側壁１０１に面した足場２１０は、その足場２１０が面した側壁１０１をメンテナンスするのに用いられる。側壁１０１に設けられる接続金具１１０の配列の仕方については図２を用いて例示的に説明したが、図１３の位置にマスト２００を立てるのであれば、接続金具１１０は、側壁１０１の幅方向の両端付近、言い換えれば側壁１０１のマスト２００と対面する部分に、垂直方向に複数存在するようにして設けられていれば良い。
　なお、図１３では、４つの側壁１０１のすべてに対して２本のマスト２００が立てられ、そこに足場２１０が取付けられることになっているが、建築物１００のメンテナンスは必ずしもすべての側壁１０１に対して同時に行う必要はない。つまり、そのときメンテナンスの対象となっている側壁１０１に対してのみ、２本のマスト２００を立て足場２１０を取付けることも可能である。例えば、図１３で言えば、実線で描かれた足場２１０がそれに面するようにされている左側の側壁１０１のメンテナンスをこの段階で行い、二点鎖線で示された足場２１０がそれに面するようにされているその他３つの側壁１０１のメンテナンスを追って行うことが可能である。 In order to perform maintenance, the mast 200 (see FIGS. 3 and 3) is placed at an appropriate position for positioning the scaffold so that the scaffold can be positioned at a portion where the scaffold is necessary for performing maintenance work. (See FIG. 13).
In this embodiment, the mast 200 is set up in the vicinity of both ends in the width direction of the side walls 101 of the building 100. The mast 200 erected near both ends in the width direction of a certain side wall 101 supports the vicinity of both ends of the scaffold 210 that substantially corresponds to the lateral width of the side wall 101. A scaffold 210 facing a certain side wall 101 is used to maintain the side wall 101 facing that scaffold 210. The method of arranging the connection fittings 110 provided on the side wall 101 has been exemplarily described with reference to FIG. 2. However, if the mast 200 is erected at the position of FIG. 13, the connection fitting 110 is arranged in the width direction of the side wall 101. It suffices if a plurality of portions are provided in the vicinity of both ends, in other words, in the portion facing the mast 200 of the side wall 101 so as to exist in the vertical direction.
In FIG. 13, two masts 200 are erected on all of the four side walls 101, and a scaffold 210 is attached thereto, but maintenance of the building 100 is not necessarily performed on all the side walls 101. It is not necessary to do it at the same time. That is, it is also possible to stand the two masts 200 and attach the scaffolding 210 only to the side wall 101 that is the object of maintenance at that time. For example, referring to FIG. 13, maintenance of the left side wall 101 where the scaffold 210 drawn with a solid line faces it is performed at this stage so that the scaffold 210 shown with a two-dot chain line faces it. It is possible to follow the maintenance of the other three side walls 101.
　マスト２００は通常、長さ方向の適当な位置で分割されたマスト体の集合とされており、それを接続していくことで、必要な高さまで上方に伸ばしていくことができる。
　まず、マスト体の下端を、地盤５００（図３参照）に公知の方法で固定する。次いで、マスト２００（地盤５００に固定したマスト体）に足場２１０を取付ける（図３、及び図１３参照）。図３に示したように、足場２１０は上述の駆動装置２２０を備えている。なお、足場２１０は本来、足場２１０に乗った作業員の安全性を確保するための、その周囲を囲む柵等の設備を備えているが、その図示も説明も省略する。
　次いで、その足場２１０に、その上に取付けるべきマスト体を載せ、足場２１０を地盤に固定されたマスト体の上方付近まで上げ、足場２１０に載せられていたマスト体を、その下のマスト体の上方に接続する。これを繰り返しながら、マスト２００は、上へ上へと伸びていく。
　また、接続金具１１０があり、マスト２００の安定性を増すためにマスト２００と接続金具１１０の接続が必要な場合には、その接続金具１１０とマスト２００の接続を行う。マスト２００と接続金具１１０の接続の方法は上述した通りであるが、マスト２００と連結金具３００とを固定するとともに、連結金具３００と接続金具１１０とを接続することにより、それを行う。なお、マスト２００と連結金具３００の接続と、連結金具３００と接続金具１１０の接続とは、いずれを先に行なっても構わない。
　以上の作業を繰り返すことにより、図３に示したように、側壁１０１に並行した状態で、略垂直にマスト２００が立てられる。
　次いで、マスト２００に取付けられた足場２１０に作業者が乗り、足場を上下させ、適当な高さで足場を止める。作業者は安全に、建築物１００のメンテナンスを行うことができる。 The mast 200 is usually a set of mast bodies divided at appropriate positions in the length direction, and can be extended upward to a required height by connecting them.
First, the lower end of the mast body is fixed to the ground 500 (see FIG. 3) by a known method. Next, the scaffold 210 is attached to the mast 200 (mast body fixed to the ground 500) (see FIG. 3 and FIG. 13). As shown in FIG. 3, the scaffold 210 includes the driving device 220 described above. The scaffold 210 is originally provided with facilities such as a fence surrounding the periphery of the scaffold 210 to ensure the safety of workers on the scaffold 210, but the illustration and description thereof are omitted.
Next, the mast body to be mounted on the scaffold 210 is placed on the scaffold 210, the scaffold 210 is raised to near the upper part of the mast body fixed to the ground, and the mast body placed on the scaffold 210 is moved to the lower mast body. Connect upward. While repeating this, the mast 200 extends upward.
In addition, when there is the connection fitting 110 and the connection of the mast 200 and the connection fitting 110 is necessary to increase the stability of the mast 200, the connection fitting 110 and the mast 200 are connected. The method for connecting the mast 200 and the connection fitting 110 is as described above, and this is done by fixing the mast 200 and the connection fitting 300 and connecting the connection fitting 300 and the connection fitting 110. It should be noted that either the connection between the mast 200 and the connection fitting 300 or the connection between the connection fitting 300 and the connection fitting 110 may be performed first.
By repeating the above operation, the mast 200 is erected substantially vertically in a state parallel to the side wall 101 as shown in FIG.
Next, an operator rides on the scaffold 210 attached to the mast 200, raises and lowers the scaffold, and stops the scaffold at an appropriate height. The worker can perform maintenance of the building 100 safely.
　メンテナンスが終わったら、マスト２００を上述の手順とは逆の作業を行うことによりマスト体に解体し、マスト体、足場２１０を搬出する。 When the maintenance is completed, the mast 200 is disassembled into a mast body by performing the reverse of the above procedure, and the mast body and the scaffold 210 are carried out.
＜変形例１＞
　次に、第１実施形態の変形例について説明する。
　第１実施形態における接続金具１１０は、側壁１０１に固定された状態で外部に露出していた。接続金具１１０は露出していない方が、建築物１００の美観という点で好ましい場合が多く、また、接続金具１１０に対して何らかの物体が係止されるという不具合も軽減される。
　変形例１の建築物１００は第１実施形態の建築物１００と略同じであり、第１実施形態の場合と同様に接続金具１１０を備えているが、変形例１の接続金具１１０は、側壁１０１に設けられた凹部１０２の内部に固定されている（図５参照）。それにより、接続金具１１０は、凹部１０２の周囲に広がる側壁１０１の略面一の面である側壁１０１の外面から露出しないようになっている。なお、変形例１では、接続金具１１０の側壁１０１への固定は、第１実施形態で説明したアンカー１１０Aが用いられているが、必ずしもかかる固定はアンカー１１０Aによらなくても良い。この事情は以下の変形例、実施形態でも同様である。
　この限りではないが、変形例１の建築物１００における凹部１０２は、その開口に対して着脱自在に取付けることのできる板状の開口蓋１０３を備えている。開口蓋１０３を開口に対して着脱自在に取付けるための方法は、周知の方法を応用することができる。開口蓋１０３が存在している場合には、接続金具１１０は、完全に外部に露出しない状態となる。また、この限りではないが、開口蓋１０３の外面は、側壁１０１の外面と同様に仕上げられている。例えば、側壁１０１の外面にタイルが貼り付けられているのであれば、それと同様のタイルが開口蓋１０３の外面に貼り付けられている。そうすることにより開口蓋１０３は、側壁１０１との馴染みの良いものとなるため、その存在が建築物１００の外観に与える影響を小さくすることができる。
　なお、接続金具１１０を凹部１０２の内部に設け、凹部１０２の開口に開口蓋１０３を設けるという以上の構造は、少なくとも一つの接続金具１１０について採用すれば良いが、この変形例１ではすべての接続金具について採用している。 <Modification 1>
Next, a modification of the first embodiment will be described.
The connection fitting 110 in the first embodiment is exposed to the outside while being fixed to the side wall 101. In many cases, it is preferable that the connection fitting 110 is not exposed in view of the beauty of the building 100, and a problem that any object is locked to the connection fitting 110 is also reduced.
The building 100 of the modification 1 is substantially the same as the building 100 of the first embodiment, and includes the connection fitting 110 as in the case of the first embodiment, but the connection fitting 110 of the modification 1 has a side wall. It is being fixed inside the recessed part 102 provided in 101 (refer FIG. 5). As a result, the connection fitting 110 is not exposed from the outer surface of the side wall 101 which is substantially flush with the side wall 101 extending around the recess 102. In the first modification, the anchor 110A described in the first embodiment is used to fix the connection fitting 110 to the side wall 101. However, the anchor 110A does not necessarily have to be fixed. This situation is the same in the following modifications and embodiments.
Although it is not this limitation, the recessed part 102 in the building 100 of the modification 1 is provided with the plate-shaped opening cover 103 which can be attached to the opening so that attachment or detachment is possible. As a method for detachably attaching the opening lid 103 to the opening, a known method can be applied. When the opening lid 103 is present, the connection fitting 110 is not completely exposed to the outside. Although not limited to this, the outer surface of the opening lid 103 is finished in the same manner as the outer surface of the side wall 101. For example, if a tile is attached to the outer surface of the side wall 101, the same tile is attached to the outer surface of the opening lid 103. By doing so, since the opening lid 103 becomes familiar with the side wall 101, the influence of the presence of the opening lid 103 on the appearance of the building 100 can be reduced.
The above-described structure in which the connection fitting 110 is provided inside the recess 102 and the opening lid 103 is provided in the opening of the recess 102 may be adopted for at least one connection fitting 110. Adopted for metal fittings.
　変形例１の建築物１００のメンテナンス方法は、基本的に第１実施形態の場合と同じである。異なるのは、マスト２００と接続金具１１０とを連結金具３００を介して接続するにあたり、接続金具１１０を外部に露出させるために、開口蓋１０３を凹部１０２の開口から外さないといけないという点である。
　なお、凹部１０２は、その内部で、接続金具１１０と、連結金具３００の把持部３０２との接続を行えるような形状、大きさになっている。凹部１０２の内部にそのような空間的な余裕があるように凹部は設計されているから、凹部１０２の中で、接続金具１１０と、連結金具３００の把持部３０２とを接続するに困難はない。
　また、メンテナンスが終了して昇降足場を撤収するに際しては、開口蓋１０３を凹部１０２の開口に再び取付けても良い、という点も変形例１と第１実施形態の相違点である。凹部１０２の中に接続金具１１０が完全に入り込んでいるので、接続金具１１０がその内部にある凹部１０２に再度開口蓋１０３で蓋を行うのは容易である。なお、凹部１０２が、その内部で、接続金具１１０と、連結金具３００の把持部３０２との接続を行えるような形状、大きさになっている点は、以下の記載でも同様である。 The maintenance method for the building 100 of the first modification is basically the same as that in the first embodiment. The difference is that when the mast 200 and the connection fitting 110 are connected via the connection fitting 300, the opening lid 103 must be removed from the opening of the recess 102 in order to expose the connection fitting 110 to the outside. .
The recess 102 has a shape and a size such that the connection fitting 110 and the holding portion 302 of the connection fitting 300 can be connected inside thereof. Since the recess is designed so that there is such a space in the interior of the recess 102, it is not difficult to connect the connection fitting 110 and the gripping portion 302 of the connection fitting 300 in the recess 102. .
Moreover, when the maintenance is completed and the lifting scaffold is withdrawn, the opening lid 103 may be reattached to the opening of the recess 102, which is a difference between the first modification and the first embodiment. Since the connection fitting 110 is completely inserted into the recess 102, it is easy for the connection fitting 110 to cover the recess 102 inside thereof again with the opening lid 103. The same applies to the following description in that the concave portion 102 has a shape and a size that allow the connection fitting 110 and the holding portion 302 of the connection fitting 300 to be connected.
　なお、変形例１では、凹部１０２の内部に接続金具１１０を取付けたが、凹部１０２の内部に接続金具１１０を取付ける構成は採用せず、側壁１０１の外面に接続金具１１０を取付けるともに、例えば一面の開口した箱状、或いはドーム状のカバーを側壁１０１に取付け、そのカバーの内部に接続金具１１０が位置するようにすることで、接続金具１１０の露出を防ぐというのも可能である。
　カバーも、その内部で、接続金具１１０と、連結金具３００の把持部３０２との接続を行えるような形状、大きさとし、その内部空間に余裕を持たせることができる。以下のカバーでも同様である。 In Modification 1, the connection fitting 110 is attached to the inside of the recess 102. However, the configuration in which the connection fitting 110 is attached to the inside of the recess 102 is not adopted, and the connection fitting 110 is attached to the outer surface of the side wall 101. It is also possible to prevent the connection fitting 110 from being exposed by attaching a box-shaped or dome-shaped cover having an opening to the side wall 101 so that the connection fitting 110 is positioned inside the cover.
The cover is also shaped and sized so that the connection fitting 110 and the gripping portion 302 of the connection fitting 300 can be connected inside thereof, so that the internal space can be given a margin. The same applies to the following covers.
＜変形例２＞
　次に、変形例２について説明する。
　変形例２の建築物１００は概ね変形例１の場合と同様である。
　図６に示されたように、接続金具１１０は、凹部１０２の内部に取り付けられる。
　ただし、変形例２では、凹部１０２の開口に開口蓋１０３はない。
　凹部１０２の内部に取付けられた接続金具１１０は、変形例１における開口蓋１０３を用いるのとは異なる方法で、その外部への露出を完全に防止されている。
　変形例２では、凹部１０２の内部に、充填材１０４を充填させることにより、接続金具１１０は、その外部への露出を完全に防止されている。充填材１０４は、粘土を始めとする粘土状のもの、モルタルを始めとするモルタル状のもの、発泡ウレタン、ウレタン、発泡スチロールなどの樹脂などである。 <Modification 2>
Next, Modification 2 will be described.
The building 100 of Modification 2 is generally the same as that of Modification 1.
As shown in FIG. 6, the connection fitting 110 is attached inside the recess 102.
However, in Modification 2, the opening lid 103 is not provided in the opening of the recess 102.
The connection fitting 110 attached to the inside of the recess 102 is completely prevented from being exposed to the outside by a method different from the method using the opening lid 103 in the first modification.
In the second modification, the connection fitting 110 is completely prevented from being exposed to the outside by filling the concave portion 102 with the filler 104. The filler 104 is a clay-like material such as clay, a mortar-like material such as mortar, or a resin such as urethane foam, urethane, or polystyrene foam.
　変形例２の建築物１００のメンテナンス方法は、基本的に変形例１の場合と同じである。異なるのは、マスト２００と接続金具１１０とを連結金具３００を介して接続するにあたり、接続金具１１０を外部に露出させるために、開口蓋１０３を凹部１０２の開口から外す代わりに、凹部１０２内の充填材１０４を除去乃至破壊して除去しないといけないという点である。つまり、この充填材１０４は、その破壊により、その内部にあった接続金具１１０を露出させるようなものとなっている。
　また、メンテナンスが終了して昇降足場を撤収するに際しては、開口蓋１０３を凹部１０２の開口に再び取付ける代わりに、凹部１０２内に充填材１０４を再度充填しても良い、という点も変形例２と変形例１の相違点であるといえる。変形例２の場合、充填材１０４の色彩や風合いを、側壁１０１の外壁のそれと合わせておくことにより、充填材１０４の外観を建築物１００の外観により馴染ませることが可能となる。 The maintenance method of the building 100 of the second modification is basically the same as that of the first modification. The difference is that, in connecting the mast 200 and the connection fitting 110 via the connection fitting 300, in order to expose the connection fitting 110 to the outside, instead of removing the opening lid 103 from the opening of the recess 102, The point is that the filler 104 must be removed or destroyed. That is, the filler 104 is configured to expose the connecting metal fitting 110 in the interior due to the destruction.
In addition, when the lifting scaffold is withdrawn after the maintenance is completed, instead of reattaching the opening lid 103 to the opening of the recess 102, the recess 104 may be filled with the filler 104 again. It can be said that this is a difference between the first modification and the first modification. In the case of the second modification, by matching the color and texture of the filler 104 with that of the outer wall of the side wall 101, the appearance of the filler 104 can be adapted to the appearance of the building 100.
　なお、変形例２では、凹部１０２の内部に接続金具１１０を取付けたが、凹部１０２の内部に接続金具１１０を取付ける構成は採用せず、側壁１０１の外面に取付けられた接続金具１１０を、そのまま上述の充填材１０４と同様の物質で覆うことも可能である。
　また、変形例２の凹部１０２の開口に、変形例１と同様の開口蓋１０３を更に取付けることも可能である（図７）。 In the second modification, the connection fitting 110 is attached to the inside of the recess 102. However, the configuration in which the connection fitting 110 is attached to the inside of the recess 102 is not adopted, and the connection fitting 110 attached to the outer surface of the side wall 101 is not changed. It is also possible to cover with the same material as the filler 104 described above.
Further, it is also possible to further attach an opening lid 103 similar to that of the first modification to the opening of the recess 102 of the second modification (FIG. 7).
＜変形例３＞
　次に、変形例３について説明する。
　変形例３の建築物１００は概ね変形例１、２の場合と同様である。
　変形例３の建築物１００の側壁１０１は、図８に示したようなパネル１０１Ｐを縦横に配列することにより構成されている。図８に示したパネル１０１Ｐは、ＡＬＣパネル又はＰＣパネルであり、コンクリート製で板状の本体１０１Ｐ１を備えている。そしてその本体１０１Ｐ１の外面には、変形例１で説明したのと同様の凹部１０２が設けられている。凹部１０２の内部には接続金具１１０が取付けられており、且つ凹部１０２の開口には開口蓋１０３が取付けられている。この実施形態では、これには限られないが、接続金具１１０のアンカー１１０Aが凹部１０２の底に埋め込まれることで、接続金具１１０が凹部１０２内に固定されている。
　このようなパネル１０１Ｐを用いた、変形例３の建築物１００は、側壁１０１がパネル１０１Ｐに分割されている点を除き、凹部１０２や接続金具１１０の位置も含めて、変形例１の建築物と同様の構成を持つものとされる。パネル１０１Ｐのうち、凹部１０２が存在しない（それにともなって、接続金具１１０及び開口蓋１０３も存在しない。）パネル１０１Ｐが存在しても良い。また、パネル１０１Ｐに複数の凹部１０２（それに加えて、接続金具１１０及び開口蓋１０３）が存在しても良い。また、パネル１０１Ｐの正面における凹部１０２（及び、接続金具１１０、並びに開口蓋１０３）の位置は、パネル１０１Ｐ毎に異なる場合もある。
　なお、変形例１、変形例２で説明した他の工夫を、変形例３のパネル１０１Ｐに応用することができる。 <Modification 3>
Next, Modification 3 will be described.
The building 100 of Modification 3 is generally the same as that of Modifications 1 and 2.
The side wall 101 of the building 100 of Modification 3 is configured by arranging panels 101P as shown in FIG. 8 vertically and horizontally. The panel 101P shown in FIG. 8 is an ALC panel or a PC panel, and includes a plate-like main body 101P1 made of concrete. A recess 102 similar to that described in the first modification is provided on the outer surface of the main body 101P1. A connection fitting 110 is attached inside the recess 102, and an opening lid 103 is attached to the opening of the recess 102. In this embodiment, although not limited thereto, the anchor 110 </ b> A of the connection fitting 110 is embedded in the bottom of the recess 102, so that the connection fitting 110 is fixed in the recess 102.
The building 100 of the modification 3 using such a panel 101P includes the position of the concave portion 102 and the connection fitting 110, except that the side wall 101 is divided into the panel 101P. It shall have the same configuration as Of the panel 101P, there may be a panel 101P in which the recess 102 does not exist (and accordingly, the connection fitting 110 and the opening lid 103 do not exist). Further, the panel 101P may have a plurality of recesses 102 (in addition to the connection fitting 110 and the opening lid 103). In addition, the position of the recess 102 (and the connection fitting 110 and the opening lid 103) on the front surface of the panel 101P may be different for each panel 101P.
Note that the other devices described in the first and second modifications can be applied to the panel 101P of the third modification.
＜変形例４＞
　次に、変形例４について説明する。
　変形例４の建築物１００は概ね変形例３の場合と同様である。
　変形例４の建築物１００の側壁１０１は、図１５に示したようなパネル１０１Ｐを縦横に配列することにより構成されている。図１５に示したパネル１０１Ｐには、変形例１で説明したのと同様の凹部１０２が設けられている。凹部１０２の内部には接続金具１１０が取付けられており、且つ凹部１０２の開口には開口蓋１０３が取付けられている。変形例４のパネル１０１Ｐが変形例３のパネル１０１Ｐと異なるのは、変形例４のパネル１０１Ｐは、本体１０１Ｐ１の外面、及びその上下左右の面が、この実施形態では金属製の板である金属板１０１Ｐ２で覆われている点である。金属板１０１Ｐ２の一部は変形例３と同様に開口蓋１０３となっていて、金属板１０１Ｐ２から、換言すればパネル１０１Ｐに対して着脱自在となっている。
　このようなパネル１０１Ｐを用いた、変形例４の建築物１００は、側壁１０１がパネル１０１Ｐに分割されている点を除き、変形例３の建築物と同様の構成を持つ。 <Modification 4>
Next, Modification 4 will be described.
The building 100 of Modification 4 is generally the same as that of Modification 3.
The side wall 101 of the building 100 of Modification 4 is configured by arranging panels 101P as shown in FIG. 15 vertically and horizontally. The panel 101P shown in FIG. 15 is provided with a recess 102 similar to that described in the first modification. A connection fitting 110 is attached inside the recess 102, and an opening lid 103 is attached to the opening of the recess 102. The panel 101P of the modification 4 is different from the panel 101P of the modification 3 in that the panel 101P of the modification 4 is a metal in which the outer surface of the main body 101P1 and its upper, lower, left, and right surfaces are metal plates in this embodiment. It is a point covered with the plate 101P2. A part of the metal plate 101P2 serves as an opening lid 103 as in the third modification, and is detachable from the metal plate 101P2, in other words, the panel 101P.
The building 100 of the modification 4 using such a panel 101P has the same configuration as the building of the modification 3 except that the side wall 101 is divided into the panels 101P.
＜変形例５＞
　次に、変形例５について説明する。
　変形例５の建築物１００は概ね第１実施形態の建築物１００と変わらない。
　変形例５の建築物１００は、第１実施形態の場合と同様ビルディングである。また、変形例５の建築物１００は、図１６に示したように、その側壁１０１の各階毎（必ずしもすべての階である必要はない。）にベランダ１０１Ｂを備えている。
　変形例５の建築物１００では、そのベランダ１０１Ｂに接続金具１１０が取付けられている。接続金具１１０は、図１７（Ａ）に示したようにベランダ１０１Ｂの下面に取付けられる場合があり、また、図１７（Ｂ）に示したようにベランダ１０１Ｂの先端面に取付けられる場合がある。接続金具１１０は、必ずしもすべてのベランダ１０１Ｂに取付けられている必要はない。また、接続金具１１０は、１つのベランダ１０１Ｂに複数取付けられていても良い。
　ベランダ１０１Ｂに接続金具１１０を固定する方法は、アンカー１１０Aを使ったものでも使わないものでも良い。ベランダ１０１Ｂに取付けられた接続金具１１０も、変形例１で説明したのと同様のカバーで隠すことができる。 <Modification 5>
Next, Modification 5 will be described.
The building 100 of the modified example 5 is almost the same as the building 100 of the first embodiment.
The building 100 of the modified example 5 is a building similar to the case of the first embodiment. Moreover, the building 100 of the modification 5 is provided with the veranda 101B for every floor (it does not necessarily need to be all the floors) of the side wall 101, as shown in FIG.
In the building 100 of the modified example 5, the connection fitting 110 is attached to the veranda 101B. The connection fitting 110 may be attached to the lower surface of the veranda 101B as shown in FIG. 17A, and may be attached to the front end surface of the veranda 101B as shown in FIG. 17B. The connection fitting 110 does not necessarily have to be attached to all the verandas 101B. A plurality of connection fittings 110 may be attached to one veranda 101B.
The method of fixing the connection fitting 110 to the veranda 101B may be either using the anchor 110A or not. The connection fitting 110 attached to the veranda 101B can also be hidden with a cover similar to that described in the first modification.
＜変形例６＞
　次に、変形例６について説明する。
　変形例６の建築物１００は概ね第１実施形態の建築物１００と同様である。変形例６の建築物１００が第１実施形態の建築物１００と異なるのは、接続金具１１０の構成である。
　この接続金具１１０は、ナットである。ナットであるこの接続金具１１０は、その内周面にネジ切りのなされたネジ穴１１７を備えている。ネジ穴１１７の、フランジで囲まれたその先端側の開口は、建築物１００の側壁１０１から外部に露出している。例えば、側壁１０１がコンクリートである場合、ナットである接続金具１１０は、その位置を図１０に示した位置に固定した状態でコンクリートを打設することにより、側壁１０１の中に埋め込まれる。接続金具１１０の基端には、幅広のフランジとして形成されたアンカー１１０Ａが設けられている。このアンカー１１０Ａの存在により、接続金具１１０Ａは側壁１０１から抜け落ちにくくなっている。
　変形例６で接続金具１１０と連結される連結金具３００は、図示を省略するが、その先端側に、ネジ穴１１７と螺合するボルトを備えている。そのボルトを、ネジ穴１１７に螺合させることにより、連結金具３００は接続金具１１０と固定される。
　なお、変形例６の接続金具１１０は、ある意味、側壁１０１に設けられた凹部に嵌め込まれているとも言える。そのようにされた接続金具１１０は、変形例１、変形例３の場合と同様に、開口蓋１０３によって、隠されていても良い。この開口蓋１０３は、変形例１、変形例３の場合と同様に側壁１０１に対して着脱自在となっていても良い（図１１）。 <Modification 6>
Next, Modification 6 will be described.
The building 100 of the modification 6 is substantially the same as the building 100 of the first embodiment. The structure 100 of the modification 6 differs from the structure 100 of the first embodiment in the configuration of the connection fitting 110.
The connection fitting 110 is a nut. The connection fitting 110, which is a nut, includes a screw hole 117 that is threaded on its inner peripheral surface. The opening on the front end side of the screw hole 117 surrounded by the flange is exposed to the outside from the side wall 101 of the building 100. For example, when the side wall 101 is concrete, the connection fitting 110 which is a nut is embedded in the side wall 101 by placing concrete in a state where the position is fixed at the position shown in FIG. An anchor 110 </ b> A formed as a wide flange is provided at the proximal end of the connection fitting 110. The presence of the anchor 110A makes it difficult for the connecting fitting 110A to fall off the side wall 101.
Although not shown in the drawings, the connection fitting 300 that is connected to the connection fitting 110 in Modification 6 includes a bolt that is screwed into the screw hole 117 on the tip side. The coupling fitting 300 is fixed to the connection fitting 110 by screwing the bolt into the screw hole 117.
In addition, it can be said that the connection fitting 110 of the modified example 6 is fitted in a recess provided in the side wall 101 in a sense. The connection fitting 110 thus configured may be hidden by the opening lid 103 as in the case of the first and third modifications. The opening lid 103 may be detachable from the side wall 101 in the same manner as in the first and third modifications (FIG. 11).
＜変形例７＞
　変形例７の建築物１００は、図１４に示したように、その側壁１０１を、多数のパネル４００により構成されている。そして隣接するパネル４００の間には間隙４０１がある。この間隙４０１はパネル４００の表面である側壁１０１の外面よりも凹んでいる。変形例７では、この間隙４０１を、変形例１、２の凹部１０２と同様に用いることとしている。
　接続金具１１０は、図１４に示したように、２枚のパネルの間の縦、横いずれかの間隙に設けることもできるし、４枚のパネルの間の２本の間隙がクロスする部分に設けることもできる。
　変形例１の開口蓋１０３、及び変形例２の充填材１０４を変形例７に応用することも可能である。 <Modification 7>
As shown in FIG. 14, the building 100 of the modified example 7 is configured with a large number of panels 400 on the side wall 101. There is a gap 401 between adjacent panels 400. The gap 401 is recessed from the outer surface of the side wall 101 that is the surface of the panel 400. In the modified example 7, the gap 401 is used in the same manner as the concave portion 102 of the modified examples 1 and 2.
As shown in FIG. 14, the connection fitting 110 can be provided in either the vertical or horizontal gap between the two panels, or at the portion where the two gaps between the four panels cross. It can also be provided.
It is also possible to apply the opening lid 103 of Modification 1 and the filler 104 of Modification 2 to Modification 7.
≪第２実施形態≫
　第２実施形態の建築物１００は、所謂構築物と呼ばれる類のものであり、より詳細には煙突である。焼却炉の煙突などには、高さ２０ｍを超える高層のものがある。
　第２実施形態の建築物１００の曲面である側壁１０１には、第１実施形態の場合と同様に多数の接続金具１１０が設けられている。
　第２実施形態の建築物１１０のメンテナンス方法も、第１実施形態の場合と同様に、マスト２００に取付けた足場２１０に乗った作業員が行う。
　第２実施形態の足場２１０は、複数の足場板２１１からできている。足場板２１１は隣接する足場板２１１との重なり幅を調節でき、且つ隣接する足場板２１１との角度を可変とされている。それにより足場２１０は、煙突である建築物１００の側壁１０１の曲率に合わせて曲折させることができる。なお、このような、伸縮と曲折を行うことのできる複数の足場板２１１を有する足場２１０を持つ昇降足場も、既に実用されている。
　図９に示した場合であれば、足場２１０は、側壁１０１の半周分に略対応するので、接続金具１１０は、煙突の中心を挟む位置に縦に２列設けられていれば、昇降足場を用いて建築物１００の側壁１０１全面のメンテナンスを行える。 << Second Embodiment >>
The building 100 of the second embodiment is a kind of so-called structure, and more specifically a chimney. Some of the chimneys of incinerators are high-rise with a height of over 20m.
On the side wall 101 which is the curved surface of the building 100 of the second embodiment, a large number of connection fittings 110 are provided as in the case of the first embodiment.
As in the case of the first embodiment, the maintenance method for the building 110 according to the second embodiment is also performed by a worker on the scaffolding 210 attached to the mast 200.
The scaffold 210 of the second embodiment is made up of a plurality of scaffold plates 211. The overlapping width of the scaffold plate 211 with the adjacent scaffold plate 211 can be adjusted, and the angle with the adjacent scaffold plate 211 is variable. Thereby, the scaffold 210 can be bent according to the curvature of the side wall 101 of the building 100 which is a chimney. In addition, the raising / lowering scaffold which has the scaffold 210 which has the several scaffold board | plate 211 which can perform such expansion-contraction and bending is already practically used.
In the case shown in FIG. 9, the scaffold 210 substantially corresponds to the half circumference of the side wall 101. Therefore, if the connecting metal fittings 110 are provided in two vertical rows at a position sandwiching the center of the chimney, the lifting scaffold is provided. By using this, maintenance of the entire side wall 101 of the building 100 can be performed.
