Abstract
Description
本発明は、例えば、外装材として用いられるスパンドレル及びこのスパンドレルを用いる外装工法に関する。 The present invention relates to, for example, a spandrel used as an exterior material and an exterior construction method using the spandrel.
従来の外装工法は、外装材としての金属製のスパンドレルを複数並べて設置することにより、ローコストで連続的に均質面を構築する工法であり、スパンドレルは、異なる面状どうしを組み合わせて使用するように作られていない。 The conventional exterior construction method is a construction method that constructs a homogeneous surface continuously at low cost by installing a plurality of metal spandrels as exterior materials. The spandrel is used by combining different planar shapes. Not made.
本発明者らは、これまで本格的に取り組まれてこなかったといっても過言ではないスパンドレルによる光の拡散や反射を積極的に利用するための構造の開発に取り組み、ランダムな凹凸を構成する外観を生み出すことが可能なスパンドレルを開発した。そして、この開発にあたり、本発明者らは、従来のスパンドレルでは、隣り合うスパンドレルとの境界部分が一律に定まった角を形成する納まりとなっており、このことが、スパンドレルによる光の拡散や反射をランダムに変化させる上でネックとなることを突き止め、その解決を図った。 The present inventors have worked on the development of a structure for actively utilizing the diffusion and reflection of light by a spandrel, which is not an exaggeration to say that it has not been tackled in earnest until now, and the appearance of forming random irregularities Developed a spandrel capable of producing In this development, the present inventors, in the conventional spandrel, are designed to form a uniform angle at the boundary between adjacent spandrels. This is the diffusion and reflection of light by the spandrel. I found out that it would become a bottleneck in changing randomly, and tried to solve it.
本発明は上述の事柄に留意してなされたもので、その目的は、隣り合うスパンドレルの境目に角をつくらずはっきりとした影が形成され難くなるスパンドレル及び外装工法を提供することにある。 The present invention has been made in consideration of the above-described matters, and an object of the present invention is to provide a spandrel and an exterior construction method in which a sharp shadow is difficult to be formed without forming a corner at the boundary between adjacent spandrels.
上記目的を達成するために、本発明に係るスパンドレルは、複数並べて設置されるスパンドレルであって、本体部と、該本体部の一端側に形成された雄部と、該本体部の他端側に形成された雌部とを具備し、前記雄部及び前記雌部は、それぞれ隣り合うスパンドレルの雌部及び雄部と係合するように形成され、前記雌部は、隣り合うスパンドレルの雄部の先端を背面側に受け入れるための突出部分を有し、該突出部分の先端部の前面は、該先端部の先端に向かうにつれて背面側に後退するように構成してある（請求項１）。 In order to achieve the above object, a span drel according to the present invention is a plurality of span drels installed side by side, and includes a main body portion, a male portion formed on one end side of the main body portion, and the other end side of the main body portion. The male part and the female part are formed to engage with the female part and the male part of the adjacent spandrel, respectively, and the female part is the male part of the adjacent spandrel. The front surface of the front end portion of the projecting portion is configured to recede toward the back surface side toward the front end of the front end portion (claim 1).
上記スパンドレルにおいて、前記本体部は、前方に迫り出す波型部分と、該波型部分の背面を覆う基板部分とを有していてもよい（請求項２）。 In the spandrel, the main body may include a corrugated portion that protrudes forward and a substrate portion that covers a back surface of the corrugated portion (claim 2).
一方、上記目的を達成するために、本発明に係る外装工法は、請求項１または２に記載のスパンドレルを外装材として複数並べて設置する外装工法であって、前記本体部の形状が互いに異なる複数の前記スパンドレルを組み合わせて用いる（請求項３）。 On the other hand, in order to achieve the above object, an exterior construction method according to the present invention is an exterior construction method in which a plurality of spandrels according to claim 1 or 2 are installed side by side as exterior materials, and the shapes of the main body portions are different from each other. The spandrel is used in combination (claim 3).
本願発明では、隣り合うスパンドレルの境目に角をつくらずはっきりとした影が形成され難くなるスパンドレル及び外装工法が得られる。 In the present invention, it is possible to obtain a spandrel and an exterior construction method in which a corner is not formed at the boundary between adjacent spandrels and a clear shadow is hardly formed.
すなわち、本願の各請求項に係る発明のスパンドレルでは、突出部分の先端部の前面を、該先端部の先端に向かうにつれて背面側に後退するように構成してあるので、隣り合うスパンドレルの境界部分にはっきりとした影が形成され難くなる。そのため、例えば、本体部の形状が互いに異なる複数種のスパンドレルを組み合わせて用いると、ランダムな外観を実現することが可能となるが、この際、このランダムな外観がはっきりとした影によって均質的になるのを防止することができる。 That is, in the spandrel of the invention according to each claim of the present application, since the front surface of the tip portion of the protruding portion is configured to recede toward the back side toward the tip of the tip portion, the boundary portion between adjacent span drels This makes it difficult to form a clear shadow. Therefore, for example, when a plurality of types of spandrels having different main body shapes are used in combination, it becomes possible to realize a random appearance. At this time, the random appearance is homogeneous with a clear shadow. Can be prevented.
請求項２に係る発明のスパンドレルでは、本体部の強度の向上を図ることが容易となる。 In the spandrel of the invention according to claim 2, it is easy to improve the strength of the main body.
請求項３に係る発明の外装工法では、本体部の形状が互いに異なる複数種のスパンドレルを組み合わせて用いることにより、ランダムな外観を実現することができ、形成された外装は、視線の移動、太陽の運行、空模様等により、輝きと色が刻々と複雑に変化し、その光の反射挙動が多様で変化に富んだものとなる。 In the exterior construction method of the invention according to claim 3, by using a combination of a plurality of types of spandrels whose main body portions are different from each other, a random appearance can be realized. Due to the operation, sky pattern, etc., the brightness and color change intricately and the reflection behavior of the light is diverse and rich.
本発明の実施の形態について図面を参照しながら以下に説明する。 Embodiments of the present invention will be described below with reference to the drawings.
本実施の形態に係る外装工法は、図１（Ａ）〜（Ｃ）に示す外装材としての三種のパネル状のスパンドレル１（１Ａ，１Ｂ，１Ｃ）を、図２及び図４に示すように、ランダムに複数並べて設置するものである。尚、本例の外装工法は、止水ラインを形成する外壁の外側にダブルスキンとしてスパンドレル１を設けるものであり、既存建築物の改修計画にも応用可能である。 As shown in FIGS. 2 and 4, the exterior construction method according to the present embodiment includes three types of panel-like spandrels 1 (1 </ b> A, 1 </ b> B, 1 </ b> C) as exterior materials shown in FIGS. These are installed at random. In addition, the exterior construction method of this example provides the spandrel 1 as a double skin on the outer side of the outer wall that forms the water stop line, and can be applied to a repair plan for an existing building.
スパンドレル１（１Ａ，１Ｂ，１Ｃ）は、アルミニウム製の押出型材によって構成され、図１（Ａ）〜（Ｃ）に示すように、本体部２と、本体部２の一端側に形成された雄部３と、本体部２の他端側に形成された雌部４とを具備し、雄部３及び雌部４は、それぞれ隣り合うスパンドレル１の雌部４及び雄部３と係合するように形成されている。 The spandrel 1 (1A, 1B, 1C) is made of an aluminum extrusion mold, and as shown in FIGS. 1 (A) to (C), a male part 2 and a male part formed on one end side of the main body part 2. Part 3 and a female part 4 formed on the other end side of main body part 2, and male part 3 and female part 4 engage with female part 4 and male part 3 of adjacent spandrel 1, respectively. Is formed.
本体部２は、前方に迫り出す波型部分５と、スパンドレル１の取付面に略平行に延び、波型部分５の背面を覆う基板部分６とを有し、波型部分５と基板部分６の間には中空部分７が形成されている。 The main body 2 includes a corrugated portion 5 that protrudes forward, and a substrate portion 6 that extends substantially parallel to the attachment surface of the spandrel 1 and covers the back surface of the corrugated portion 5, and the corrugated portion 5 and the substrate portion 6. A hollow portion 7 is formed between them.
雄部３は、先端が背面側に向かって折れ曲がった形状を呈する。 The male part 3 has a shape in which the tip is bent toward the back side.
雌部４は、隣り合うスパンドレル１の雄部３の先端を背面側に受け入れるための突出部分８と、この突出部分８の背面側に位置し、突出部分８よりも側方に延びる取付部分９とを有する。なお、突出部分８と取付部分９とは、ともにスパンドレル１の取付面と略平行に延び、取付部分９において突出部分８の背面側に隠れない部分には、固定部材（例えばねじ部材）１０（図２、図５参照）用の貫通孔１１が形成されている。 The female part 4 has a protruding part 8 for receiving the tip of the male part 3 of the adjacent spandrel 1 on the back side, and a mounting part 9 that is located on the back side of the protruding part 8 and extends to the side of the protruding part 8. And have. The protruding portion 8 and the mounting portion 9 both extend substantially parallel to the mounting surface of the spandrel 1, and a fixing member (for example, a screw member) 10 (on the portion of the mounting portion 9 that is not hidden behind the protruding portion 8) A through hole 11 is formed for use (see FIGS. 2 and 5).
そして、本例の三種のスパンドレル１は、波型部分５が各々異なり、図１（Ａ）に示すスパンドレル１Ａの波型部分５は、凸部を一つのみ有する形状を呈し、図１（Ｂ）に示すスパンドレル１Ａの波型部分５は、凸部を二つ有する形状を呈し、図１（Ｃ）に示すスパンドレル１Ａの波型部分５は、凸部を三つ有する形状を呈する。 The three types of spandrel 1 of this example are different from each other in the corrugated portion 5, and the corrugated portion 5 of the spandrel 1A shown in FIG. 1A has a shape having only one convex portion, and FIG. The corrugated portion 5 of the spandrel 1A shown in FIG. 1 has a shape having two convex portions, and the corrugated portion 5 of the span drel 1A shown in FIG. 1C has a shape having three convex portions.
ここで、スパンドレル１Ａの波型部分５の凸部の左右の曲面は、図３に示すように、凸部の深さを４ａとしたときに、その倍の８ａを短径とし、その三倍の１２ａを長径とする楕円の全周の四分の一に重なる形状を呈する。 Here, as shown in FIG. 3, the left and right curved surfaces of the convex portion of the corrugated portion 5 of the spandrel 1A have a short diameter of 8a, which is twice as long as the depth of the convex portion, and three times that No. 12a has a shape that overlaps a quarter of the entire circumference of an ellipse having a major axis.
スパンドレル１Ｂの波型部分５の二つの凸部の各々左右の曲面は、図３に示すように、その凸部の深さを４ａとしたときに、その倍の８ａを長径とし、その１．５倍の６ａを短径とする楕円の全周の四分の一に重なる形状を呈する。 As shown in FIG. 3, the left and right curved surfaces of the two convex portions of the corrugated portion 5 of the spandrel 1 </ b> B have a long diameter of 8a, twice as long as the depth of the convex portion is 4 a. It has a shape that overlaps a quarter of the entire circumference of an ellipse having a minor axis of 5 times 6a.
スパンドレル１Ｃの波型部分５の三つの凸部の各々左右の曲面は、図３に示すように、その凸部の深さを４ａとしたときに、その倍の８ａを長径とし、その０．７５倍の３ａを短径とする楕円の全周の四分の一に重なる形状を呈する。 As shown in FIG. 3, each of the left and right curved surfaces of the three convex portions of the corrugated portion 5 of the spandrel 1C has a long diameter of 8a, when the depth of the convex portion is 4a. It has a shape that overlaps a quarter of the entire circumference of an ellipse having a minor axis of 75 times 3a.
一方、スパンドレル１Ａ，１Ｂ，１Ｃの左右幅（雄部３の先端から雌部４の突出部分８の先端までの距離）は共通（本例では１７０．３８ｍｍ）であり、波型部分５の凸部の深さ（奥行）も共通（本例では５３ｍｍ）である。 On the other hand, the span widths 1A, 1B, and 1C (the distance from the tip of the male portion 3 to the tip of the protruding portion 8 of the female portion 4) are common (in this example, 170.38 mm), and the corrugated portion 5 is convex. The depth (depth) of the part is also common (in this example, 53 mm).
本例の外装工法では、上述したように、本体部２（波型部分５）の形状が互いに異なる三種のスパンドレル１Ａ，１Ｂ，１Ｃを組み合わせて用いることにより、ランダムな外観を生み出すことができる。すなわち、各スパンドレル１の波型部分５が有する凸部の奥行を一定にして凸部の幅を変える（４：２：１にする）ことにより、凸部の左右に三種の曲面が形成されるようにしている。そのため、スパンドレル１Ａ，１Ｂ，１Ｃの各凸部の左右の曲面をそれぞれＡ，Ｂ，Ｃとすると、これら三種の曲面Ａ，Ｂ，Ｃから六種の反射断面ＡＡ，ＡＢ（ＢＡ），ＡＣ（ＣＡ），ＢＢ，ＢＣ（ＣＢ），ＣＣが形成されることになる（図２参照）。従って、スパンドレル１Ａ，１Ｂ，１Ｃの配置をランダムに行えば（図４参照）、形成された外装は、視線の移動、太陽の運行、空模様等により、輝きと色が刻々と複雑に変化し、その光の反射挙動が多様で変化に富んだものとなる。 In the exterior construction method of this example, as described above, a random appearance can be created by using a combination of three types of spandrels 1A, 1B, and 1C having different shapes of the main body 2 (the corrugated portion 5). That is, by changing the width of the convex portion while keeping the depth of the convex portion of the corrugated portion 5 of each spandrel 1 constant (4: 2: 1), three types of curved surfaces are formed on the left and right sides of the convex portion. I am doing so. Therefore, if the left and right curved surfaces of the convex portions of the spandrels 1A, 1B, and 1C are respectively A, B, and C, six types of reflection cross sections AA, AB (BA), and AC ( CA), BB, BC (CB), and CC are formed (see FIG. 2). Therefore, if the arrangement of the spandrels 1A, 1B, and 1C is performed randomly (see FIG. 4), the formed exterior changes in complexity and shine due to movement of the line of sight, operation of the sun, sky pattern, etc. The reflection behavior of the light is diverse and varied.
しかも、本例の三種のスパンドレル１は、図５に示すように、突出部分７の先端部の前面は、曲面状（断面半円状）であるので、隣り合うスパンドレル１の境界部分にはっきりとした影が形成され難くなっている。そのため、上述したランダムな外観がはっきりとした影によって均質的になるのを防止することもできる。 In addition, as shown in FIG. 5, the three types of spandrel 1 of the present example have a curved surface (a semicircular cross section) at the front end of the protruding portion 7. It is difficult to form shadows. Therefore, it is possible to prevent the random appearance described above from becoming homogeneous due to a clear shadow.
また、突出部分７の先端部に丸みを帯びせることにより、スパンドレル１を並べて設置する際にスパンドレル１が傷つきにくくなるという効果も得られる。 In addition, by rounding the tip of the protruding portion 7, it is possible to obtain an effect that the span drel 1 is less likely to be damaged when the span drel 1 is installed side by side.
さらに、基板部分６を設けつつ波型部分５を前方に大きく迫り出させることにより、本体部２の強度が向上するリブ効果もが得られることになる。 Furthermore, the rib effect which the intensity | strength of the main-body part 2 improves by obtaining the waveform part 5 largely protruding ahead while providing the board | substrate part 6 is also acquired.
なお、本発明は、上記の実施の形態に何ら限定されず、本発明の要旨を逸脱しない範囲において種々に変形して実施し得ることは勿論である。例えば、以下のような変形例を挙げることができる。 In addition, this invention is not limited to said embodiment at all, Of course, it can change and implement variously in the range which does not deviate from the summary of this invention. For example, the following modifications can be given.
図１（Ａ）〜（Ｃ）に示すスパンドレル１は、各々凸部が略左右対称に構成されているが、これに限らず、左右非対称に構成されていてもよい。図６には、コーナー部分に設置されるスパンドレル１Ｄが、左右非対称な二つの凸部を有する例を示している。 1 (A) to 1 (C), the convex portions are configured to be substantially bilaterally symmetric, but the present invention is not limited thereto and may be configured to be bilaterally asymmetric. FIG. 6 shows an example in which the spandrel 1D installed at the corner portion has two left and right asymmetric convex portions.
また、波型部分５の形状は、矩形波状、正弦波状、三角波状等、種々の形状とすることが考えられ、その凸部の数も単複何れであってもよい。 Further, the shape of the corrugated portion 5 may be various shapes such as a rectangular wave shape, a sine wave shape, and a triangular wave shape, and the number of convex portions may be single or plural.
また、図４には、突出部分８の先端が半円状に丸みを帯びた断面形状を呈する例を示しているが、これに限らず、例えば、図７（Ａ）〜（Ｄ）に示すように、突出部分８の先端が、先端に向かって細くなるテーパーがついた断面形状や、先端の角が部分的あるいは全体的に落とされた断面形状を呈するものであってもよい。いずれにしても、隣り合うスパンドレル１の境界部分にはっきりとした影を形成しないようにするという目的からは、突出部分８の先端部の前面を、先端部の先端に向かうにつれて背面側に漸次的に後退するように構成してあるのが好ましい。 FIG. 4 shows an example in which the tip of the protruding portion 8 has a semicircular round cross-sectional shape. However, the present invention is not limited to this, and for example, shown in FIGS. 7 (A) to (D). As described above, the tip of the protruding portion 8 may have a cross-sectional shape with a taper that becomes narrower toward the tip, or a cross-sectional shape in which the corner of the tip is partially or entirely dropped. In any case, for the purpose of preventing a clear shadow from being formed on the boundary portion between adjacent spandrels 1, the front surface of the tip portion of the projecting portion 8 is gradually moved to the back surface side toward the tip of the tip portion. It is preferable to be configured to retreat.
なお、本明細書で挙げた変形例どうしを適宜組み合わせてもよいことはいうまでもない。 Needless to say, the modifications described in this specification may be combined as appropriate.
