A partial perspective view showing a joint portion of a wall body in an object, FIG. 5 is a partially enlarged view of FIG. 1, and FIG. 6 is a view taken along the line A of FIG.

図1から図6において、1は、壁体としての一対の側部壁、2は、側部壁1間を連結する壁体としての頂部壁、3は、側部壁1と頂部壁2とを補強する骨組である。 1 to 6, 1 is a pair of side walls as a wall body, 2 is a top wall as a wall body connecting the side walls 1, and 3 is a side wall 1 and a top wall 2. It is a skeleton that reinforces.

側部壁1と頂部壁2とは、波付け方向と直交する方向に弧状に折り曲げられた大型デッキプレートからなる波形鋼板からなり、それぞれの波形寸法は、同一である。側部壁1と頂部壁2とは、ボルト4(図2、図3参照)によりアーチ状に接合されている。骨組3は、H形鋼等の形鋼からなり、基礎5上に台座6を介して固定されている。側部壁1と頂部壁2とは、形鋼等の取付け部材7によって骨組3の外側に取り付けられている。 The side wall 1 and the top wall 2 are made of corrugated steel plates made of large deck plates bent in an arc shape in a direction orthogonal to the corrugating direction, and their corrugated dimensions are the same. The side wall 1 and the top wall 2 are joined in an arch shape by bolts 4 (see FIGS. 2 and 3). The frame 3 is made of shaped steel such as H-shaped steel, and is fixed on the foundation 5 via a pedestal 6. The side wall 1 and the top wall 2 are attached to the outside of the frame 3 by an attachment member 7 such as a shaped steel.

側部壁1の上端部には、段差絞り加工が施され、これによって段部8が形成されている(図4参照)。頂部壁2の端部は、側部壁1の上端部上に重ね合わされ、頂部壁2の端部は、側部壁2の段差絞り加工が施されることによって形成された段部8に当接する。この結果、段部8が頂部壁2のストッパーの作用をするので、アーチ状構造物に内側に向かって作用する力に対するアーチ状構造物の強度が上昇する。 The upper end portion of the side wall 1 is subjected to a step drawing process, whereby a step portion 8 is formed (see FIG. 4). The end portion of the top wall 2 is overlapped on the upper end portion of the side wall 1, and the end portion of the top wall 2 hits the step portion 8 formed by the step drawing process of the side wall 2. Contact. As a result, since the step portion 8 acts as a stopper for the top wall 2, the strength of the arch-shaped structure against the force acting inward on the arch-shaped structure increases.

また、段差絞り加工を側部壁1の上端部に施し、側部壁1の上端部上に頂部壁2の端部を重ね合わすことによって、側部壁1と頂部壁2との接合部からの雨水等の浸入を防止することができる。 Further, by applying a step drawing process to the upper end portion of the side wall 1 and superimposing the end portion of the top wall 2 on the upper end portion of the side wall 1, from the joint portion between the side wall 1 and the top wall 2. It is possible to prevent the infiltration of rainwater and the like.

また、段差絞り加工を側部壁1の上端部に施し、側部壁1の上端部上に頂部壁2の端部を重ね合わすことによって、側部壁1と頂部壁2との接合部に段差が形成されないので、外観が優れる。 Further, by applying a step drawing process to the upper end portion of the side wall 1 and superimposing the end portion of the top wall 2 on the upper end portion of the side wall 1, the joint portion between the side wall 1 and the top wall 2 is formed. Since no step is formed, the appearance is excellent.

次に、この発明のアーチ状構造物における壁体の別の例について説明する。 Next, another example of the wall body in the arched structure of the present invention will be described.

図7は、この発明のアーチ状構造物における壁体の別の例を示す部分斜視図、図8は、図7の壁体を別の方向から見た部分斜視図、図9は、図7の壁体を使用した場合の壁体の接合部を示す部分斜視図である。 7 is a partial perspective view showing another example of the wall body in the arched structure of the present invention, FIG. 8 is a partial perspective view of the wall body of FIG. 7 from another direction, and FIG. 9 is FIG. 7. It is a partial perspective view which shows the joint part of the wall body when the wall body of is used.

図7から図9に示すように、この別の壁体は、段差絞り加工が施された壁体の端部の谷部の幅を先広がりテーパー状に形成したものである。 As shown in FIGS. 7 to 9, this other wall body is formed in a tapered shape in which the width of the valley portion at the end of the wall body that has been subjected to the step drawing process is widened and tapered.

この別の壁体を、上述したスノーシェルターに適用した場合で説明すると、側部壁1の端部の谷部の幅は、先広がりテーパー状に形成されている。すなわち、図8に示すように、側部壁1の谷部の幅をB1とすると、側部壁1の端部の谷部の幅B2は、テーパー状に広がっている。すなわち、B1<B2になっている。これにより、図8に示すように、側部壁1の山部の幅をT1とすると、側部壁1の端部の山部の幅T2は、テーパー状に狭まっている。すなわち、T2<T1になっている。 Explaining the case where this other wall body is applied to the above-mentioned snow shelter, the width of the valley portion at the end of the side wall 1 is formed in a tapered shape. That is, as shown in FIG. 8, assuming that the width of the valley portion of the side wall 1 is B1, the width B2 of the valley portion at the end portion of the side wall 1 is widened in a tapered shape. That is, B1 <B2. As a result, as shown in FIG. 8, assuming that the width of the mountain portion of the side wall 1 is T1, the width T2 of the mountain portion at the end portion of the side wall 1 is narrowed in a tapered shape. That is, T2 <T1.

これによって、図9に示すように、側部壁1の上端部上に頂部壁2の端部を重ね合せた場合、図7に示すように、側部壁1と頂部壁2との接合部の可動域が広がるので、アーチ状構造物を曲線状に構築することが容易に行える。図7に、接合部の可動域をLで示す。 As a result, as shown in FIG. 9, when the end portion of the top wall 2 is overlapped on the upper end portion of the side wall 1, the joint portion between the side wall 1 and the top wall 2 is as shown in FIG. Since the range of motion of the arched structure is widened, it is easy to construct the arched structure in a curved shape. FIG. 7 shows the range of motion of the joint in L.

以上の例では、一箇所の接合部の谷部および山部のボルト4の本数がそれぞれ2本になっているが、ボルト4の本数を1本にすることによって、接合部の可動域がより広くなる。 In the above example, the number of bolts 4 in the valley and the mountain of one joint is two, but by reducing the number of bolts 4 to one, the range of motion of the joint can be increased. It gets wider.

以上、説明したように、この発明によれば、波付け方向と直交する方向に弧状に折り曲げられた波形鋼板からなる側部壁1および頂部壁2を、アーチ状に接合することにより構築されるアーチ状構造物において、側部壁1の上端部に段差絞り加工を施し、頂部壁2の端部を、側部壁1の上端部上に重ね合わせることによって、側部壁1と頂部壁2との接合部に段差が形成されないので、外観が優れる。 As described above, according to the present invention, it is constructed by joining the side wall 1 and the top wall 2 made of corrugated steel plates bent in an arc shape in a direction orthogonal to the wavy direction in an arch shape. In the arched structure, the upper end portion of the side wall 1 is subjected to a step drawing process, and the end portion of the top wall 2 is overlapped on the upper end portion of the side wall 1, so that the side wall 1 and the top wall 2 are overlapped. Since no step is formed at the joint with the wall, the appearance is excellent.

また、この発明によれば、段差絞り加工が施された側部壁1の上端部の谷部の幅を、先広がりテーパー状に形成することによって、側部壁1と頂部壁2との接合部の可動域が広がるので、アーチ状構造物を曲線状に構築することが容易に行える。 Further, according to the present invention, the width of the valley portion of the upper end portion of the side wall 1 that has been subjected to the step drawing process is formed in a tapered shape so as to join the side wall 1 and the top wall 2. Since the movable range of the portion is widened, the arch-shaped structure can be easily constructed in a curved shape.

また、この発明によれば、側部壁1の上端部に段差絞り加工を施し、頂部壁2の端部を、側部壁1の上端部上に重ね合わせることによって、側部壁1と頂部壁2との接合部からの雨水等の浸入を防止することができる。 Further, according to the present invention, the upper end portion of the side wall 1 is subjected to a step drawing process, and the end portion of the top wall 2 is overlapped on the upper end portion of the side wall 1, so that the side wall 1 and the top portion are overlapped. It is possible to prevent rainwater or the like from entering from the joint with the wall 2.

また、この発明によれば、側部壁1の上端部に段差絞り加工を施し、頂部壁2の端部を、側部壁1の上端部上に重ね合わせることによって、頂部壁2の端部が側部壁1の段差絞り加工が施されることによって形成された段部8に当接する結果、この段部8が頂部壁2のストッパーの作用をするので、アーチ状構造物に内側に向かって作用する力に対するアーチ状構造物の強度が上昇する。 Further, according to the present invention, the upper end portion of the side wall 1 is subjected to a step drawing process, and the end portion of the top wall 2 is overlapped on the upper end portion of the side wall 1, so that the end portion of the top wall 2 is overlapped. As a result of contacting the stepped portion 8 formed by the step drawing of the side wall 1, the stepped portion 8 acts as a stopper for the top wall 2 and thus faces the arched structure inward. The strength of the arched structure against the acting force increases.
