【発明の属する技術分野】
本発明は水道管又はヒーター付き水道管を収納して気温から断熱保護する水道管用養生管並びにその養生管施工方法に関する。
【０００２】
【従来の技術】
従来、水道管が気温の影響を受けないように収納して、断熱保護する養生管が使用されている。特に、寒冷地では建物の外部に配置する水道管の凍結を防止するため、その外周にニクロム線のヒーターコードを巻き付けた後に、その外側に養生管を施工する。その際には、図６に示すように養生管をほぼ同一形状、構造の２等分割型にする。そして、その各管部材１（１ａ、１ｂ）は図６に示すような本体２とそこに一体に施した外装３との二重構造にし、その本体２には接触面４に水道管又はヒーター付き水道管収納用凹所５を一端面から他端面まで貫いて設けた断熱材を用い、その外装３にはプラスチック製シートを用いる。
【０００３】
すると、施工時に両管部材１の収納用凹所５内に水道管６又はヒーター７付き水道管６を収納し、その接触面４同士を合せ結合して管体にし、養生管を形成できる。なお、両管部材１を結合するため、一方の例えば管部材１ｂの接触面４の両端に内面に接着剤を貼付したシート状の結合用突部８（８ａ、８ｂ）を夫々設けておく。
【０００４】
このような水道管は一般的施工方法によると、施工時に一端に取付部９を設け、他端に巻付部１０を設けた金属製ブラケット１１を用いる。そして、ブラケット１１毎にその取付部９を水道管配置箇所の付近にある建物の外壁、躯体等に固定して取り付ける。次に、そのブラケット１１の巻付部１０を水道管６の外周に１回り巻き付けて、ブラケット１１で水道管６を支持する。その後、水道管６に養生管の施工を行なう、或いは水道管６にヒーター７を巻き付けた後に、養生管の施工を行なうという工程を踏む。それ故、養生管を形成する管部材１の少なくとも一方、例えば管部材１ａを一部切り欠いて、ブラケット１１の腕部１２が通るブラケット設置穴１３を形成しなければならない。なお、養生管を用いない場合には、水道管６にヒーター７を巻き付けた後、更にそれ等の上に断熱材シートを巻き付けてビニールテープ等で留める。
【０００５】
【発明が解決しようとする課題】
しかしながら、このように管部材１にブラケット設置穴１３を設けると、外部の冷気がその穴１３から直接入り込んで水道管６に接触し、同時に冷気の温度がブラケット１１を介して水道管６に伝達する。それ故、養生管施工による断熱作用が損なわれ易い。又、養生管施工が複雑化し、施工時間が長くなり易い。しかも、養生管の外装３としてプラスチック製シートを施しておくと、その外装３が短期間の内に劣化し易く、外装３に穴が開き、又めくれて内部の断熱材２が露出して外観が悪くなる。
【０００６】
本発明はこのような従来の問題点に着目してなされたものであり、外装の強度を増して養生管の強度を大きくし、ブラケット設置穴を開ける必要をなくし、断熱作用に優れ、施工が容易で、施工時間が短く、外装が劣化し難く、長期間経過しても外観を維持できる水道管用養生管並びにその養生管施工方法を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上記目的を達成するために、本発明による水道管用金属外装養生管は、外装を施し、接触面の中央に水道管又はヒーター付き水道管収納用凹所を一端面から他端面まで貫いて設けた断熱材からなる管部材を２個用いて対にし、施工時に両管部材の収納用凹所内に水道管又はヒーター付き水道管を収納し、その両接触面同士を合せ結合して管体を形成する。そして上記外装に金属体を用いる。
又、上記金属体をアルミニウム製にすると好ましくなる。
又、上記金属体に塗装を施してカラー化するとよい。
【０００８】
又、本発明による水道管用金属外装養生管施工方法では、一端に取付部を設け、他端に巻付部を設けたブラケットを用い、そのブラケットの取付部を水道管配置箇所の付近に固定し、その巻付部を水道管又はヒーター付き水道管を収納した養生管の外周の少なくとも一部に巻き付けて施工する。
【０００９】
【発明の実施の形態】
以下、添付の図１〜５を参照して、本発明の実施の形態を説明する。
図１は本発明を適用したストレート水道管用金属外装養生管の施工過程を示す斜視図、図２はその金属外装養生管の施工に用いるブラケットの主要部を示す斜視図である。このストレート水道管用金属外装養生管は、図１に示すようにやはり外装１４を施した本体１５からなる二重構造の管体にして、２等分割型にする。しかし、各管部材１６（１６ａ、１６ｂ）の外装１４には強度を大きくするため、アルミニウム、ステンレス等の金属体例えば厚みが０．１〜０．２ｍｍ程の半円筒体を用いる。その際、アルミニウム製の半円筒体を用いると、比較的柔らかであるため、切断等の加工が容易であり好都合となる。
【００１０】
そして、本体１５には例えば従来と同様の接触面１７に水道管６又はヒーター７付き水道管６を収納する収納用の凹所１８を一端面から他端面まで貫いて設けた断熱材、例えばポリウレタン等のプラスチック製発泡断熱材を用いる。なお、各管部材１６の製造工程で外装１４を本体１５に施す際、リサイクルに備えて接着箇所を少なくし、両者を分離し易くしておく。
【００１１】
このような金属外装養生管の施工には、図２に示すようなＴ字状金具１９とリング状金具２０とを組み合せ、更に図示を省略した２個の止めねじと、２組のボルト、ナットとを用いたブラケット２１を用いる。そして、Ｔ字状金具１９の長穴２２を２箇所に設けた長方形状板体２３をブラケット２１の腕部にする。又、その板体２３の一端に結合している丸穴２４を２箇所設けた長方形状板体２５をブラケット２１の取付部にする。
【００１２】
又、リング状金具２０の中央に丁番２６を設けた板状円リング部２７をブラケット２１の巻付部にする。又、その巻付部２７の一端から丸穴２８を２箇所設けた長めの長方形状板体２９を突設し、その他端から丸穴３０を１箇所設けた短めの長方形状板体３１を突設して、それ等の両板体２９、３１を腕部２３の両側に配置し、その腕部２３との夫々結合部にする。なお、巻付部２７にはその内面中央にリングに沿って合成ゴム等からなる帯状の弾性部材３２を配設しておく。
【００１３】
施工時、建物、躯体等の外部に水道管を付設する場合、ブラケット２１を必要数用意し、その各ブラケット２１を建物の外壁、躯体等の水道管配置箇所に沿わせて順次配置して取り付ける。その際、各ブラケット２１毎に、先ずＴ字状金具１９の取付部２５を両丸穴２４にねじ３３を嵌めて建物の外壁、躯体等に夫々固定する。すると、その取付部２５を建物の外壁、躯体等の例えば垂直部に固定した時に、腕部２３の主面を水平にできる。
【００１４】
次に、そのＴ字状金具１９に対し、リング状金具２０を取り付け固定する。その際、リング状金具２０の長め結合部２９をＴ字状金具１９の腕部２３に結合するが、先に長め結合部２９の先端側、腕部２３の基端側のみを対応する丸穴２８と長穴２２とにボルト３４を嵌め、ナット３５で締め付けて結合する。すると、リング状金具２０の巻付部２７の丁番２６で分かれる半円状の下半分が受部になり、その半円状上半分が丁番２６により開閉自在になる。
【００１５】
そこで、水道管配置箇所に沿って水平方向に配置されている複数のブラケット２１を利用し、各ブラケット２１の巻付部２７の下半分内に、先ず一方の管部材１６ａを入れる。次に、その管部材１６ａの収納用凹所１８に水道管６又はヒーター７付き水道管６を収納し、更に各ブラケット２１の巻付部２７の下半分内に他方の管部材１６ｂを入れる。次に、両管部材１６の接触面１７同士を合せ、その両合せ目を片面に接着剤を貼付したアルミニウム等の金属テープを用いて塞ぎ、両管部材１６を結合する。
【００１６】
すると、管体が形成でき、養生管の本体が完成する。そこで、本体の両端部に、図３に示すようなアルミニウム等の金属製エンドキャップ３６を夫々施す。すると、本体両端の切断面をキャップ３６で各々隠して整えた養生管が完成する。なお、３７は水道管６又はヒーター７付き水道管６を通す挿通穴である。
【００１７】
次に、ブラケット２１の巻付部２７の下半分で支えた養生管上に、その巻付部２７の上半分を夫々被せる。その後、長め結合部２９の基端側、腕部２３の先端側、短め結合部３１を重ね合わせ、対応する丸穴２８、３０、長穴２３にボルトを嵌め、ナットで締め付けて結合する。すると、ブラケット２１の巻付部２７を、水道管６又はヒーター７付き水道管６を収納した養生管の外周全体に巻き付け、それ等を水平方向に配置し、良好に支持できる。
【００１８】
このようにして、外装１４に金属体を施し強度を増して養生管の強度を大きくし、その外周にブラケット２１の巻付部２７を巻き付けて施工すると、養生管に水道管６を支えるブラケット設置穴を開ける必要がない。それ故、養生管の断熱作用を損なうことがなく、優れた断熱効果を発揮できる。又、養生管とその内部に収納した水道管６又はヒーター７付き水道管６とを一度に施工すると、その養生管にブラケット設置穴を開ける必要もないので、施工が容易であり、施工時間を短くできる。又、養生管の外装１４に金属体を施しておくと、長期間経過してもその外装１４が劣化し難く、外観を維持できる。
【００１９】
又、このような養生管の外装１４たる金属体に塗装を施してカラー化すると、塗装により外装１４の強度が更に増して外装１４が一層劣化し難くなり、建物の外壁、躯体等の色に一致した色選択が可能になって、建物、躯体等の美観を損うことなく維持できる。又、養生管を廃棄処理する場合には外装１４たる金属体と本体１５たる断熱材との接着箇所を少なくして分離し易くしておくことにより、両者を簡単に分離できる。それ故、外装１４たるアルミニウム等の金属体をリサイクルし、残りの本体１５たる断熱材を廃棄処分すると、廃棄物を少なくすることができる。
【００２０】
上記の実施の形態ではブラケット２１の巻付部２７を養生管の外周全体に巻き付ける場合について説明したが、養生管をブラケットにより支持できれば、ブラケットの巻付部を養生管の外周の一部のみに巻き付けて施工してもよい。
【００２１】
又、上記の実施の形態ではストレートの水道管を収納するため、養生管がストレートである場合について説明したが、Ｌ字状に屈曲する水道管を収納するには、図４に示すような対となるＬ字状管部材３８（３８ａ、３８ｂ）を用いて、Ｌ字状養生管を形成する。なお、３９は外装たる金属体、４０は本体たる断熱材、４１はその断熱材４０に設けた収納用凹所である。
又、Ｔ字状に結合する水道管を収納するには、図５に示すような対となるＴ字状管部材４２（４２ａ、４２ｂ）を用いて、Ｔ字状養生管を形成する。なお、４３は外装たる金属体、４４は本体たる断熱材、４５はその断熱材４４に設けた収納凹所である。
【００２２】
【発明の効果】
以上説明した本発明によれば、請求項１記載の発明では外装に金属体を施して外装の強度を増し、養生管の強度を大きくすることにより、その外周をブラケットで直接支持できる。それ故、養生管に水道管を支えるブラケット設置穴を開ける必要がなく、養生管の断熱作用を損なわないので、優れた断熱効果を発揮できる。
【００２３】
又、養生管とその内部に収納した水道管又はヒーター付き水道管とを一度に施工でき、その養生管にブラケット設置穴を開ける必要もないので、施工が容易であり、施工時間を短くできる。又、養生管の外装として金属体を施しておくと、その外装が劣化し難く、長期間経過しても外観を損なわずに維持できる。
【００２４】
又、請求項２記載の発明では外装たる金属体をアルミニウム製にすることにより、アルミニウムが比較的柔らかで、切断等の加工が容易であるため、施工に好都合となる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a water pipe curing pipe for accommodating a water pipe or a water pipe with a heater for insulation protection from temperature, and a method for constructing the curing pipe.
[0002]
[Prior art]
Conventionally, a curing pipe has been used in which a water pipe is housed so as not to be affected by the temperature and is insulated and protected. In particular, in cold regions, in order to prevent water pipes placed outside the building from freezing, a heater cord of a nichrome wire is wound around the outer periphery of the pipe, and then a curing pipe is constructed on the outside thereof. In this case, as shown in FIG. 6, the curing tube is made into a two-part split type having substantially the same shape and structure. Each of the pipe members 1 (1a, 1b) has a double structure of a main body 2 and an exterior 3 integrally provided thereon as shown in FIG. A heat insulating material provided with a water pipe storage recess 5 penetrating from one end face to the other end face is used, and a plastic sheet is used for the exterior 3.
[0003]
Then, at the time of construction, the water pipe 6 or the water pipe 6 with the heater 7 is stored in the storage recess 5 of the both pipe members 1, and the contact surfaces 4 are joined together to form a pipe, thereby forming a curing pipe. In order to connect the two pipe members 1, for example, sheet-like connecting projections 8 (8a, 8b) each having an adhesive adhered to the inner surface thereof are provided at both ends of the contact surface 4 of one of the tube members 1b, for example.
[0004]
According to a general construction method, such a water pipe uses a metal bracket 11 provided with a mounting portion 9 at one end and a winding portion 10 at the other end at the time of construction. Then, for each bracket 11, the mounting portion 9 is fixed to and attached to an outer wall, a skeleton, or the like of a building near a water pipe arrangement location. Next, the winding part 10 of the bracket 11 is wound around the outer periphery of the water pipe 6 once, and the water pipe 6 is supported by the bracket 11. Thereafter, a step of performing the curing pipe on the water pipe 6 or winding the heater 7 around the water pipe 6 and then performing the construction of the curing pipe is performed. Therefore, at least one of the tube members 1 forming the curing tube, for example, the tube member 1a must be partially cut out to form a bracket installation hole 13 through which the arm portion 12 of the bracket 11 passes. When the curing pipe is not used, the heater 7 is wound around the water pipe 6, and then a heat insulating material sheet is further wound thereon and fastened with a vinyl tape or the like.
[0005]
[Problems to be solved by the invention]
However, when the bracket installation hole 13 is provided in the pipe member 1 in this manner, external cold air enters directly through the hole 13 and contacts the water pipe 6, and at the same time, the temperature of the cold air is transmitted to the water pipe 6 via the bracket 11. I do. Therefore, the heat insulating effect by the construction of the curing pipe is easily damaged. In addition, the curing pipe construction becomes complicated, and the construction time tends to be long. Moreover, if a plastic sheet is applied as the exterior 3 of the curing pipe, the exterior 3 is liable to deteriorate in a short period of time, a hole is opened in the exterior 3, and the inside heat insulating material 2 is exposed and the exterior 3 is exposed. Gets worse.
[0006]
The present invention has been made in view of such conventional problems, and increases the strength of the exterior to increase the strength of the curing pipe, eliminates the need to drill bracket mounting holes, has excellent heat insulating action, and construction is excellent. An object of the present invention is to provide a water pipe curing pipe that is easy, has a short construction time, hardly deteriorates the exterior, and can maintain its appearance even after a long period of time, and a method for constructing the curing pipe.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a metal exterior curing pipe for a water pipe according to the present invention is provided with an exterior, and a water pipe or a water pipe storage recess with a heater is provided in the center of the contact surface so as to penetrate from one end face to the other end face. Two pipe members made of heat insulating material are used as a pair, and a water pipe or a water pipe with a heater is stored in the storage recess of both pipe members at the time of construction, and the contact surfaces thereof are joined together to form a pipe body. I do. Then, a metal body is used for the exterior.
It is preferable that the metal body is made of aluminum.
Further, it is preferable that the above-mentioned metal body is painted and colored.
[0008]
Further, in the method for constructing a metal exterior curing pipe for a water pipe according to the present invention, a mounting part is provided at one end, and a bracket provided with a winding part at the other end is used, and the mounting part of the bracket is fixed in the vicinity of the location of the water pipe. The wound part is wound around at least a part of the outer circumference of a curing pipe containing a water pipe or a water pipe with a heater.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a perspective view showing a construction process of a metal exterior curing pipe for a straight water pipe to which the present invention is applied, and FIG. 2 is a perspective view showing a main part of a bracket used for construction of the metal exterior curing pipe. As shown in FIG. 1, this straight water pipe metal exterior curing pipe is a two-part pipe having a double structure composed of a main body 15 also provided with an exterior 14. However, in order to increase the strength, a metal body such as aluminum or stainless steel, for example, a semi-cylindrical body having a thickness of about 0.1 to 0.2 mm is used for the exterior 14 of each pipe member 16 (16a, 16b). At that time, if a semi-cylindrical body made of aluminum is used, it is relatively soft, so that processing such as cutting is easy and convenient.
[0010]
A heat insulating material, such as polyurethane, is provided in the main body 15 such that a recess 18 for accommodating the water pipe 6 or the water pipe 6 with the heater 7 is penetrated from one end face to the other end face on the contact surface 17 similar to the conventional one. Use plastic foam insulation such as. When the exterior 14 is applied to the main body 15 in the manufacturing process of each tube member 16, the number of bonded portions is reduced in preparation for recycling, and the two are easily separated.
[0011]
For the construction of such a metal exterior curing tube, a T-shaped fitting 19 and a ring-shaped fitting 20 as shown in FIG. 2 are combined, and two set screws (not shown) and two sets of bolts and nuts are omitted. Is used. Then, a rectangular plate 23 provided with two long holes 22 of the T-shaped fitting 19 is used as an arm of the bracket 21. In addition, a rectangular plate 25 having two round holes 24 connected to one end of the plate 23 is used as a mounting portion of the bracket 21.
[0012]
Further, a plate-shaped circular ring portion 27 provided with a hinge 26 at the center of the ring-shaped bracket 20 is used as a winding portion of the bracket 21. A long rectangular plate body 29 having two round holes 28 protruded from one end of the winding portion 27 and a short rectangular plate body 31 having one round hole 30 protruded from the other end. The two plate bodies 29 and 31 are arranged on both sides of the arm 23, and serve as joints with the arm 23. Note that a band-shaped elastic member 32 made of synthetic rubber or the like is provided in the center of the inner surface of the winding portion 27 along the ring.
[0013]
At the time of construction, when attaching a water pipe outside a building, a skeleton, etc., a necessary number of brackets 21 are prepared, and the brackets 21 are sequentially arranged and attached along the outer wall of the building, the location of the water pipe, such as the skeleton. . At this time, for each bracket 21, first, the mounting portion 25 of the T-shaped bracket 19 is fixed to the outer wall, the building, or the like of the building by fitting the screws 33 into the both round holes 24. Then, when the mounting portion 25 is fixed to, for example, a vertical portion such as an outer wall or a frame of a building, the main surface of the arm portion 23 can be made horizontal.
[0014]
Next, the ring-shaped fitting 20 is attached and fixed to the T-shaped fitting 19. At this time, the long connecting portion 29 of the ring-shaped fitting 20 is connected to the arm 23 of the T-shaped fitting 19, but only the distal end side of the long connecting portion 29 and the base end of the arm 23 correspond to the corresponding round holes. A bolt 34 is fitted into the elongated hole 28 and the elongated hole 22, and the bolt 34 is fastened with a nut 35 for connection. Then, the lower half of the semicircular shape divided by the hinge 26 of the winding portion 27 of the ring-shaped metal fitting 20 becomes the receiving portion, and the upper half of the semicircular shape can be opened and closed by the hinge 26.
[0015]
Therefore, one of the pipe members 16a is first inserted into the lower half of the winding portion 27 of each bracket 21 by using a plurality of brackets 21 arranged in the horizontal direction along the water pipe arrangement location. Next, the water pipe 6 or the water pipe 6 with the heater 7 is stored in the storage recess 18 of the pipe member 16a, and the other pipe member 16b is put in the lower half of the winding portion 27 of each bracket 21. Next, the contact surfaces 17 of the two pipe members 16 are joined together, and both joints are closed with a metal tape such as aluminum having an adhesive stuck on one side, and the two pipe members 16 are joined.
[0016]
Then, a tube can be formed, and the main body of the curing tube is completed. Therefore, end caps 36 made of metal such as aluminum as shown in FIG. 3 are provided on both ends of the main body. Then, a curing tube in which the cut surfaces at both ends of the main body are hidden by the caps 36 and trimmed is completed. Reference numeral 37 denotes an insertion hole through which the water pipe 6 or the water pipe 6 with the heater 7 passes.
[0017]
Next, the upper half of the winding part 27 is put on the curing pipe supported by the lower half of the winding part 27 of the bracket 21, respectively. Thereafter, the base end side of the long connecting portion 29, the distal end side of the arm portion 23, and the short connecting portion 31 are overlapped, bolts are fitted into the corresponding round holes 28, 30, and the long hole 23, and tightened with a nut to be connected. Then, the winding part 27 of the bracket 21 is wound around the entire outer periphery of the water pipe 6 or the curing pipe containing the water pipe 6 with the heater 7, and these are arranged in the horizontal direction, so that they can be favorably supported.
[0018]
In this way, when the metal body is applied to the exterior 14 and the strength is increased to increase the strength of the curing pipe, and the winding portion 27 of the bracket 21 is wound around the outer periphery thereof, the bracket is installed to support the water pipe 6 on the curing pipe. There is no need to make holes. Therefore, an excellent heat insulating effect can be exhibited without impairing the heat insulating effect of the curing pipe. Further, when the curing pipe and the water pipe 6 housed in the curing pipe or the water pipe 6 with the heater 7 are constructed at one time, there is no need to drill a bracket installation hole in the curing pipe, so the construction is easy and the construction time is reduced. Can be shortened. In addition, if a metal body is applied to the exterior 14 of the curing tube, the exterior 14 is hardly deteriorated even after a long period of time, and the appearance can be maintained.
[0019]
In addition, when a color is applied to the metal body which is the exterior 14 of such a curing pipe by painting, the strength of the exterior 14 is further increased by the coating, and the exterior 14 is hardly deteriorated. Matching color selection becomes possible, and it is possible to maintain the appearance of buildings, frames, and the like without impairing them. When the curing tube is discarded, the metal body serving as the exterior 14 and the heat insulating material serving as the main body 15 can be easily separated from each other by reducing the number of adhesion points and facilitating separation. Therefore, when the metal body such as aluminum as the exterior 14 is recycled and the remaining heat insulating material as the main body 15 is discarded, the amount of waste can be reduced.
[0020]
In the above-described embodiment, the case where the winding portion 27 of the bracket 21 is wound around the entire outer periphery of the curing tube has been described. However, if the curing tube can be supported by the bracket, the winding portion of the bracket may be limited to only a part of the outer periphery of the curing tube. It may be wound and constructed.
[0021]
Further, in the above-described embodiment, the case where the curing pipe is straight is described in order to store the straight water pipe. However, in order to store the L-shaped bent water pipe, a pair as shown in FIG. An L-shaped curing pipe is formed using the L-shaped pipe member 38 (38a, 38b). In addition, 39 is a metal body as an exterior, 40 is a heat insulating material as a main body, and 41 is a storage recess provided in the heat insulating material 40.
In addition, in order to store a water pipe connected in a T shape, a T-shaped curing pipe is formed by using a pair of T-shaped pipe members 42 (42a, 42b) as shown in FIG. In addition, 43 is a metal body as an exterior, 44 is a heat insulator as a main body, and 45 is a storage recess provided in the heat insulator 44.
[0022]
【The invention's effect】
According to the present invention described above, in the first aspect of the present invention, the outer periphery can be directly supported by the bracket by increasing the strength of the outer casing by applying a metal body to the outer casing and increasing the strength of the curing tube. Therefore, it is not necessary to make a bracket installation hole for supporting the water pipe in the curing pipe, and the heat insulating effect of the curing pipe is not impaired, so that an excellent heat insulating effect can be exhibited.
[0023]
Further, the curing pipe and the water pipe housed therein or the water pipe with a heater can be constructed at once, and it is not necessary to make a bracket installation hole in the curing pipe, so that the construction is easy and the construction time can be shortened. Further, if a metal body is provided as an exterior of the curing tube, the exterior is hardly deteriorated, and can be maintained without deterioration even after a long period of time.
[0024]
According to the second aspect of the present invention, since the metal body as the exterior is made of aluminum, the aluminum is relatively soft and the processing such as cutting is easy, which is convenient for construction.
[0025]
According to the third aspect of the present invention, by applying a color to a metal body as an exterior by applying a coating, the strength of the exterior can be further increased, and the exterior can be further hardly deteriorated. In addition, the color of the curing tube can be selected so as to match the color of the outer wall of the building, the skeleton, and the like, and the appearance of the building, the skeleton, and the like can be maintained without impairing the appearance.
