Description
本発明は、立体トラスの単位架構となる４面体架構の接合装置及びそれを用いた構造物に関するものである。 The present invention relates to a joining device for a tetrahedral frame, which is a unit frame for a three-dimensional truss, and a structure using the same.
接合基材を介して軸材を相互に接合して４面体架構を造り、４面体架構を相互に接合して立体トラスを構築するための接合装置の技術及びそれを用いて構築する構造物の技術を提案した。（特許文献１参照） Joining shaft materials to each other via a joining base material to form a tetrahedral frame, joining a tetrahedral frame to each other to construct a solid truss, and a structure to be constructed using the same Proposed technology. (See Patent Document 1)
前記技術の接合基材は、正４面体を４等分割した接合基材の元の正４面体の面にねじ孔を３本、元の正４面体の中心に向けて、相互の角度を６０度にして設け、さらに接合基材を相互に接合するためにボルト孔を３箇所設けた接合基材であった。従って、その接合基材は、所定の大きさが必要とされ、例えば、２階建ての住宅を建てる人工地盤を構築するため、１６５.２φ×６.０ｍｍの軸材を相互に接合して４面体架構を造り、さらにその４面体架構を相互に接合するために、接合基材のねじ孔とボルト孔を設ける面に少なくとも直径４００φｍｍの面を必要とした。その接合基材（ジョイント）は、人力で持ち上げることができない。また、海洋構造物等のために防食性の高いチタンを使用するとなると質量の大きい分だけ非常に高価になる。接合装置の質量を最小にすることが望まれる。
本発明の接合装置と軸材を用いた構造物は、溶接を必要としない。従って、チタンなどの防食性の高い部材による接合装置と軸材を用いることによって永久的な構造物も可能である。
The joining base material of the above-mentioned technique is such that the regular tetrahedron is divided into four equal parts, the screw base has three screw holes on the surface of the original regular tetrahedron, and the angle of the mutual base is 60. It was a joined base material provided with three bolt holes for joining the joined base materials to each other. Therefore, the joining base material is required to have a predetermined size. For example, in order to construct an artificial ground for constructing a two-story house, 165.2φ × 6.0 mm shaft members are joined to each other. In order to make a face frame and to join the tetrahedron frames to each other, it is necessary to provide a surface having a screw hole and a bolt hole on the bonding base material with a diameter of at least 400 mm. The joining base material (joint) cannot be lifted manually. Further, when titanium having high anticorrosion properties is used for an offshore structure or the like, it becomes very expensive due to its large mass. It is desirable to minimize the mass of the joining device.
The structure using the joining device and shaft material of the present invention does not require welding. Therefore, a permanent structure can be obtained by using a joining device and a shaft member made of a highly corrosion-resistant member such as titanium.

(36).
構造骨組を３角形で構成された立体トラスにすることによって部材の質量を、架構が４角形で構成されるラーメン構造の約５０％〜６０％にすることができる。また、３角形による構成なので、軸材の接合はボルト１本で済み、構造物の組立、解体が容易である。 The mass of the member can be reduced to about 50% to 60% of the rigid frame structure in which the frame is a quadrangle by using a three-dimensional truss having a triangular structure. In addition, since the structure is a triangle, the joining of the shaft member is only one bolt, and the assembly and disassembly of the structure is easy.
４個の接合基材（ジョイント）を用いて軸材を相互に接合して４面体架構を造り、連接し、立体トラス構造の構造物を構築する。従ってその構築は、地上であればクレーンととび職によって、水上であれば４面体架構内に浮体を入れて水上に浮かべることによって可能である。仮設足場を必要としないのでコストがかからず、足場のない傾斜地、水上、宇宙空間等に構築できる。軸材を相互にヒンジ接合することによって、４面体架構は、軸材（傾斜部材）の長さの調整だけで、傾斜地にも自由に接地できる。構造物の拡大、縮小も自由にできる。 The shaft members are joined to each other using four joining base materials (joints) to form a tetrahedral frame, and connected to construct a structure having a three-dimensional truss structure. Therefore, it can be constructed by cranes and jumpers on the ground and by floating on a tetrahedral frame and floating on the water. Since there is no need for a temporary scaffold, there is no cost, and it can be built on slopes, water, and outer space without a scaffold. By connecting the shaft members to each other by hinges, the tetrahedral frame can be freely grounded on the sloped land only by adjusting the length of the shaft member (inclined member). The structure can be expanded and contracted freely.
４面体架構の接合装置の質量を小さくし、人力でも持ち上げられる大きさにすることによって、４面体架構の組み立てを容易にすることができる。また、防食性が高く高価なチタンなどの材料も使用しやすくなり、海洋構造物等に供することもできる。 Assembling of the tetrahedral frame can be facilitated by reducing the mass of the tetrahedral frame joining device so that it can be lifted by human power. In addition, it is easy to use an expensive material such as titanium that has high anticorrosion properties, and can be used for offshore structures.
以下、本発明を図示する実施形態に基づいて説明する。
図１の図（Ａ）は接合装置実施例の平面図、図（Ｂ）は接合装置実施例の正面図、図（Ｃ）は接合装置実施例の背面図である。図６において、立体トラスを構築するまでの過程を、Ａ、Ｂ、Ｃの３段階に分けて図示する。
立体トラス構造の単位架構となる４面体架構（１１）を造り、４面体架構（１１）を相互に接合して立体トラス構造物（１２）を構築する接合装置であって、
平面視３角形またはＹの字型にして、端部に接合のためのボルト孔（１３）を設け
背面視３角形またはＹの字型の中心部（１８）と前記ボルト孔（１３）中心を結ぶ稜線（１４）を１２０度、稜線（１４）相互の実際の角度を１０９.５度にして設けてなる第１の接合基材（１）と、
端部にボルト孔（１７）一つを有した孔付プレート（１５）を３枚鉛直にして、平面視相互の角度を１２０度にしてつなげてなる第２の接合基材（２）を備え、
第２の接合基材（２）を第１の接合基材（１）に垂直に、
平面視第１の接合基材（１）の中心（１６）とボルト孔（１３）中心を結ぶ線（３０）と、第２の接合基材（２）の中心（１６）と（１５）の端部を結ぶ線（４０）の角度を６０度に、
前記（１５）端部のボルト孔（１７）中心と第１の接合基材（１）裏面の稜線（１４）の交点（１８）を結ぶ線（１９）の相互の実際の角度を６０度に配置し、接合して第３の接合基材（３）を造り、
４面体架構（１１）の上部材である上弦材（２０）または４面体架構（１１）の傾斜部材（２１）の各端部を、第３の接合基材（３）の孔付プレート（１５）に接合し（Ａ）（図６のＡ参照）、
上弦材（２０）または傾斜部材（２１）の各端部を、第３の接合基材（３）を介し相互に接合して４面体架構（１１）を造り、４面体架構の前記第３の接合基材（３）裏面の稜線（１４）を相互に合わせ（Ｂ）（図６のＢ参照）、
前記４面体架構（１１）を、上弦材（２０）を重複しないように連接し、
外周部位置する上弦材交点（２６）を、前記接合基材（１）に接合されたボルト（５２）と上弦つなぎ材（２２）を接合し（Ｃ）（図６のＣ参照）、つなぐことによって、立体トラス構造物（１２）を構築できることを特徴とする接合装置である。
図２は、本発明の原理を示す図である。正４面体（１１０）の中心（１８０）と正４面体（１１０）の端部（１２０）を結ぶ線（１４０）の相互の角度が１０９.５度であることを示している。前記接合基材（１）裏面の稜線（１４）は、この線（１４０）に相当する。４個の接合基材（３）を相互に背面を合わせて合体することができるのである。図６参照。
接合基材（２）を、ヒンジ付プレート（１５）を３枚垂直に、平面視相互の角度を１２０度になるように合わせ、前記３枚の孔付プレート（１５）端部にボルト孔（１７）を設け、前記孔付プレート（１５）端部のボルト孔（１７）中心と第１の接合基材（１）裏面の稜線（１４）の交点（１８）を結ぶ線（１９）の相互の実際の角度が６０度になるようにしたのは、第３の接合基材（３）を介して上弦材（２０）または傾斜部材（２１）を相互に接合して正４面体架構（１１）を造れるようにし、正４面体架構（１１）を連接して立体トラスを構築した時に、全ての上弦材（２０）及び傾斜部材（２１）が一直線状になるようにするためである。そうすることによって、接合部に曲げ応力が生じず、接合部の部材断面を最小にすることができる。第１の接合基材（１）の端部の厚み（４７）及び中央部の厚み（４８）を構造強度的に必要最小限にして、第１の接合基材（１）を加工することによって、第１の接合基材（１）の質量を最小にすることができる。第２の接合基材（２）についても同様である。
傾斜部材（２１）と接合基材（３）をヒンジ接合することによって傾斜部材（２１）の角度を変えることは可能である（図１０のＺ０〜Ｚ１参照）。
軸材を上弦材（２０）と傾斜部材（２１）に分けているのは、地上または水面上の構造物は一般的に床を受ける上弦材を必要とするので、軸材を上弦材（２０）と傾斜部材（２１）に区別している。
「外周部上弦材交点（２６）を、第１の接合基材（１）に接合されたボルト（５２）と上弦つなぎ材（２２）を接合し、つなぐ」の実施例は、図８によって示される。図（Ａ）〜（Ｃ）は、接合基材（３Ａ）にヒンジ付きボルト（４３）が接合されており、そのヒンジ付きボルト（４３）によって上弦材交点（２６）と上弦つなぎ材（２２）が接合され、上弦材交点（２６）が上弦つなぎ材（２２）によってつながれる。ヒンジ付きボルト（４３）とボルト（５２）は同じものであって良い。上弦材交点（２６）が上弦つなぎ材（２２）によってつながれる実施例は、図１１によっても示されている。上弦材交点（２６）とは、隣接する上弦材（２０）どうしを接合するための交点です。
第１の接合基材（１）を平面視概略３角形またはＹの字型とし、図１の（１）で３角形の場合を、図３でＹの字型とした場合を示している。概略３角形の場合は、第１の接合基材（１）と第２の接合基材（２）の接合長さが取れるので、第２の接合基材（２）の厚みを最小にしても、第１の接合基材（１）と第２の接合基材（２）の必要な接合面積を得やすい。図３のようにして第１の接合基材（１）と第２の接合基材（２）の必要な接合面積が得られる、または、一体加工して必要な強度が得られるのであれば、第１の接合基材（１）をＹの字型として第３の接合基材（３）の質量を小さくすることができる。
図６は、４基の４面体架構（１１）が連接される直前の配置を示している。第３の接合基材（３）裏面の稜線（１４）相互の実際の角度が１０９.５度であることによって、４個の第３の接合基材（３）が隙間なく接合されるのである。上段の４面体架構（１１）を無くする場合には、接合部（Ｂ）において、第３の接合基材（３）を上部において接合する。または、図２の４面体の中心（１８０）を上げて、上部の３角形の中心にした場合の稜線（１４０）を用いた接合基材に、第３の接合基材（３）を変えることによって、前記の上部におく第３の接合基材（３）を無くすることができる。
図７の（Ａ）は、４個の４面体架構（１１）を連接した接合部の平面図を示しており、同時に図６を、４面体架構（１１）が接合された後中央の接合部を上から見た図でもある。
図７の（Ｂ）は、図７の（Ａ）の正面図である。図７の（Ａ）において、３個の４面体架構（１１）の上弦材（２０）相互の角度６０度を示し、図７の（Ｂ）において、上弦材（２０）が水平になっていることが示されている。

The ends of the upper chord member (20) or the inclined member (21) are joined to each other via the third joining base material (3) to form a tetrahedral frame (11), and the third structure of the tetrahedral frame is formed . Bonding substrate (3) ridge lines (14) on the back surface are aligned with each other (B) (see B in FIG. 6),
The tetrahedral frame (11) is connected so as not to overlap the upper chord material (20),
Join the upper chord material intersection (26) located at the outer peripheral portion by joining the bolt (52) joined to the joining base material (1) and the upper chord joint material (22) (C) (see C in FIG. 6). By this, the three-dimensional truss structure (12) can be constructed.
FIG. 2 is a diagram showing the principle of the present invention. The mutual angle of the line (140) connecting the center (180) of the regular tetrahedron (110) and the end (120) of the regular tetrahedron (110) is 109.5 degrees. The ridge line (14) on the back surface of the bonding substrate (1) corresponds to this line (140). Four joining base materials (3) can be united together with their back surfaces aligned. See FIG.
Bonding substrate (2), vertically three plates hinged (15), combined angle in plan view each other such that the 120 degrees, the three perforated plates (15) end to the bolt hole ( 17), and the line (19) connecting the intersection (18) of the center of the bolt hole (17) at the end of the plate (15) with the hole and the ridge line (14) on the back surface of the first joining base (1) actual the angle was set to 60 degrees, upper chord member through a third bonding substrate (3) to (20) or inclined member (21) joined to each other regular tetrahedron Frame (11 ), And when the three-dimensional truss is constructed by connecting the regular tetrahedral frame (11), all the upper chord members (20) and the inclined members (21) are arranged in a straight line. By doing so, no bending stress is generated in the joint, and the member cross section of the joint can be minimized. By processing the first bonding substrate (1) with the thickness (47) of the end portion and the thickness (48) of the central portion of the first bonding substrate (1) set to the minimum necessary for structural strength. The mass of the first bonding substrate (1) can be minimized. The same applies to the second bonding substrate (2).
The angle of the inclined member (21) can be changed by hinge-joining the inclined member (21) and the joining base material (3) (see Z0 to Z1 in FIG. 10).
The shaft material is divided into the upper chord material (20) and the inclined member (21) because the structure on the ground surface or the water surface generally requires the upper chord material to receive the floor. ) And the inclined member (21).
Example of "the outer peripheral portion upper chord member intersections (26), joined joined bolts in the first bonding substrate (1) and (52) top chord ties (22), connecting" is illustrated by Figure 8 It is. In FIGS. (A) to (C), a hinged bolt (43) is joined to the joining base material (3A), and the upper chord material intersection (26) and the upper chord connecting material (22) are joined by the hinged bolt (43). Are joined, and the upper chord material intersection (26) is connected by the upper chord connecting material (22). The hinged bolt (43) and the bolt (52) may be the same. An embodiment in which the upper chord material intersection (26) is connected by the upper chord joint (22) is also shown in FIG. The upper chord material intersection (26) is the intersection for joining adjacent upper chord materials (20).
The first bonding base material (1) has a triangular shape or Y shape in plan view, and the case of the triangular shape in FIG. 1 (1) is the Y shape in FIG. In the case of a roughly triangular shape, since the joining length of the first joining base material (1) and the second joining base material (2) can be taken, the thickness of the second joining base material (2) can be minimized. It is easy to obtain the necessary bonding area of the first bonding substrate (1) and the second bonding substrate (2). If the required bonding area of the first bonding substrate (1) and the second bonding substrate (2) can be obtained as shown in FIG. 3, or the necessary strength can be obtained by integral processing, The mass of the third bonding substrate (3) can be reduced by using the first bonding substrate (1) as a Y-shape.
FIG. 6 shows an arrangement immediately before the four tetrahedral frames (11) are connected. Since the actual angle between the third bonding substrate (3) and the ridge line (14) on the back surface is 109.5 degrees, the four third bonding substrates (3) are bonded without gaps. . When the upper tetrahedral frame (11) is eliminated, the third bonding substrate (3) is bonded at the upper portion at the bonding portion (B). Alternatively, the third bonding substrate (3) is changed to a bonding substrate using the ridgeline (140) when the center (180) of the tetrahedron in FIG. 2 is raised to the center of the upper triangle. Thus, the third bonding substrate (3) placed on the upper portion can be eliminated.
FIG. 7A shows a plan view of a joint portion in which four tetrahedral frames (11) are connected, and FIG. 6 shows a joint portion in the center after the tetrahedral frame (11) is joined. It is the figure which looked at from the top.
FIG. 7B is a front view of FIG. 7A shows the angle of 60 degrees between the upper chord members (20) of the three tetrahedral frames (11). In FIG. 7B, the upper chord member (20) is horizontal. It has been shown.
