Description
本考案は、丸棒を使ったドーム型骨組み構造に関するものである。 The present invention relates to a dome-type frame structure using a round bar.
多面体ドームを形成する方法はいろいろ提案されているが、専用のジョイント金物によってジョイント部を回転自在のピンで結合させ、ドーム形状を形作っていく方法の提案が多い。Various methods for forming a polyhedral dome have been proposed, but there are many proposals for forming a dome shape by connecting joints with a rotatable pin using a dedicated joint hardware.
材の軸方向の抵抗力だけで荷重を受けるトラス型骨組構造であり、ジョイント部に荷重が集中することにより、ジョイント部に強度が求められ、材や金物に高度な強度が求められ特殊な専用金物が必要である。 A truss-type frame structure that receives load only by the axial resistance of the material. When the load concentrates on the joint, strength is required in the joint, and high strength is required in the material and hardware. Hardware is necessary.
精密に計算されたデータが必要で、製作には高度な技術と機械、大がかりな工場が必要である。
本考案は、これらの問題を解決するためになされたものである。Precisely calculated data is required, and advanced technology, machinery, and a large factory are required for production.
The present invention has been made to solve these problems.
本考案のドーム型構造体（Ｅ）は、一定の長さの丸棒（Ａ）の両端を横から見るとハの字になるように鋭角に斜めに切断して、両端に楕円形の切断面（１，１）を形成せしめ、こうして得られた楕円断面付丸棒（Ｂ）三本を各々楕円形の切断面（１）同士を接合させて三角枠素体（Ｃ）を形成させ、この三角枠素体（Ｃ）を多数個用意し、この三角枠素体（Ｃ）同士を隣り合う状態で並べ、構成する楕円断面付丸棒（Ｂ）同士を長さを合わせて結束材（（２）にて、半束縛状態で結束し、このような作業を繰り返し多面体の骨組み（Ｄ）を形成させ、この多面体の骨組（Ｄ）を多数個結合させて得られることを特徴とする。 The dome-shaped structure (E) of the present invention has a round bar (A) of a certain length cut obliquely at an acute angle so that it looks like a letter C when viewed from the side, and an elliptical cut at both ends. The surface (1, 1) is formed, and the three round bars (B) with an elliptical cross section thus obtained are joined to each other with the elliptical cut surfaces (1) to form a triangular frame body (C), A large number of triangular frame elements (C) are prepared, the triangular frame elements (C) are arranged next to each other, and the round bars (B) with elliptical cross sections (B) are combined to form a binding material ( It is characterized in that it is obtained in (2) by binding in a semi-constrained state, repeating such operations to form a polyhedral framework (D), and joining a number of the polyhedral framework (D).
本考案で用いる丸棒（Ａ）とは、例えば、間伐材そのまま、アルミなどの金属製丸棒、プラスチック製丸棒、などが挙げられるが、自然材の活用や環境問題の解決、現地での入手し易さから、間伐材を用いるのが好ましい。The round bar (A) used in the present invention includes, for example, thinned wood as it is, metal round bars such as aluminum, plastic round bars, etc. It is preferable to use thinned wood because of its availability.
本考案で用いる丸棒（Ａ）の一定の長さとは、得ようとするドーム型構造体（Ｅ）の形状や大きさによって、予め計算された長さである。The fixed length of the round bar (A) used in the present invention is a length calculated in advance depending on the shape and size of the dome-shaped structure (E) to be obtained.
本考案では、丸棒（Ａ）の両端を横から見るとハの字状になるよう鋭角に斜めに切断するが、この角度は、得ようとするドーム型構造体（Ｅ）の形状や大きさによって決める。おおむね２５度から３５度がよい。 In the present invention, when both ends of the round bar (A) are viewed from the side, it is cut obliquely at an acute angle so that it becomes a C shape. This angle depends on the shape and size of the dome-shaped structure (E) to be obtained. Decide on it. A good range is 25 to 35 degrees.
本考案で、楕円断面付丸棒（Ｂ）三本を各々楕円形の切断面（１）同士を接合させて三角枠素体（Ｃ）を形成させるのであるが、接合の仕方には、釘、ボルト、ねじ、ダボ接合などいずれでもよく、しっかり接合できればよい。In the present invention, three round bars (B) having an elliptical cross section are joined to each other by cutting the elliptical cut surfaces (1) to form a triangular frame element (C). , Bolts, screws, dowel joints, etc., all are acceptable as long as they can be firmly joined.
本考案で得られた三角枠素体（Ｃ）同士を接合するための結束材としては、針金、紐、バンド、麻縄、プラスチック製のリング体などが挙げられる。Examples of the binding material for joining the triangular frame bodies (C) obtained by the present invention include a wire, a string, a band, a hemp rope, and a plastic ring.
本考案でいう半束縛状とは、楕円断面付丸棒（Ｂ）が長手方向同士に当接したまま、互いの楕円断面付丸棒（Ｂ）は楕円断面付丸棒（Ｂ）と長手方向の軸中心に回転できる状態となるように縛る状態を言う。結束した三角枠素体（Ｃ）が形成する面を、隣の三角枠素体（Ｃ）の形成する面との角度を調整しながら、多面体の骨組み（Ｄ）を形成するための自由度をもった結合状態にするためである。In the present invention, the semi-constrained shape means that the round bars with elliptical cross section (B) are in contact with each other in the longitudinal direction, and the round bars with elliptical cross section (B) are in the longitudinal direction with the round bar with elliptical section (B). The state of being bound so that it can be rotated about the axis center. While adjusting the angle of the surface formed by the bound triangular frame body (C) with the surface formed by the adjacent triangular frame body (C), the degree of freedom for forming the polyhedral frame (D) is increased. This is to achieve a combined state.
本考案でいう多面体の骨組み（Ｄ）とは、前述のように三角枠素体（Ｃ）を結束して得るものであり、多面体の骨組み（Ｄ）としては、５角形又は６角形として用いるのがドーム型構造体（Ｅ）を形成するのに適当である。The polyhedral framework (D) in the present invention is obtained by binding the triangular frame element (C) as described above, and the polyhedral framework (D) is used as a pentagon or a hexagon. Is suitable for forming the dome-shaped structure (E).
複数種類から成る三角枠素体を、辺と辺を接続してドーム型構造体を形成することによって、建設が容易になる。 Construction can be facilitated by connecting a plurality of types of triangular frame elements to each other to form a dome-shaped structure.
三角枠素体を構成する長さや三角枠素体の数を変えることによってドーム型構造体の大きさや形状を変えることができる。 The size and shape of the dome-shaped structure can be changed by changing the length of the triangular frame element and the number of triangular frame elements.
材料のある場所で、一般的な工具があれば誰でも製作することができる。特殊金物や大掛かりな工場がなくてもできる。 Anyone with a general tool can make it where there is material. It can be done without special hardware or a large factory.
本考案で用いる丸棒の材料としては、木材、金属、プラスチック等が挙げられ、中でもコスト、使いやすさ、環境問題等考慮すると間伐材が望ましい。 The round bar material used in the present invention includes wood, metal, plastic, etc. Among them, thinned wood is preferable in consideration of cost, ease of use, environmental problems, and the like.
