As shown in FIGS. 1 and 2, the cylindrical structure 10 includes an outer cylindrical membrane 1 made of aramid fibers arranged in the longitudinal direction, circumferential direction, and diagonal direction, and a cylindrical structure 1 arranged on the inner surface of the outer cylindrical membrane 1. The inner cylinder membrane 2 is provided with an injection port 2a projecting outward from the outer cylinder membrane 1, and air is introduced into the inner cylinder membrane 2 from the injection port 2a. It is sealed up to a predetermined pressure. The cylindrical structure 10 is just a flexible membrane when air is not sealed in it, but when it is filled with air up to a predetermined pressure, it is held in a preset shape. Here, the aramid fiber that is the material of the outer cylinder membrane 1 has a high tensile strength of 310 kg・f/mm 2 (the tensile strength is 40 to 50 kg・f/mm 2 for steel material, and 250 to 420 kg・f/mm 2 for carbon fiber) kg・f/mm 2 , glass fiber: 220 kg・f/mm 2 ), and has a low specific gravity of 1.39 (specific gravity is 7.85 for steel, 1.80 for carbon fiber, and 2.54 for glass fiber), making it an unparalleled high material. It has impact strength, heat resistance, chemical resistance, and excellent fatigue strength. In addition, the outer cylinder membrane 1 has a pressing fiber material 3 wound around the aramid fiber materials in the three directions further outside to press them, and an opening/closing valve 4 is provided at the injection port 2a of the inner cylinder membrane 2. ing.
【０００８】 上記構成により、筒状構造体10は主として、アラミド繊維材よりなる外筒膜１ と合成ゴムからなる内筒膜２とから構成されるため超軽量であり、また内部に所 定圧力の空気が封入されることにより、高引張強度のアラミド繊維材よりなる外 筒膜１はあらかじめ引張り応力を与えられ、これにより引張り，圧縮，曲げ，せ ん断，捩りなどの外力に対して大きな強度が発揮される。しかも、構造体として 使用しない際には空気を抜くことによりコンパクト化できて、収納，搬送に便利 であり、また、再度空気を封入することにより所定形状とすることができる。[0008] With the above configuration, the cylindrical structure 10 mainly consists of an outer cylindrical membrane 1 made of aramid fiber material. and an inner cylinder membrane 2 made of synthetic rubber, it is extremely lightweight and has no internal space. By enclosing air at a constant pressure, the outer material is made of aramid fiber material with high tensile strength. The cylindrical membrane 1 is given a tensile stress in advance, which causes it to undergo tension, compression, bending, and shearing. It exhibits great strength against external forces such as shearing and torsion. Moreover, as a structure When not in use, it can be made compact by deflating, making it convenient for storage and transportation. Moreover, it can be made into a predetermined shape by enclosing air again.

In Fig. 3, 11 is a lightweight joint made of aluminum, and an uneven part 12 is formed on the inner surface. It has a cylindrical opening 13. The cylindrical opening 13 of this lightweight joint 11 has a cylindrical shape before being pressurized. By inserting the end of the structure 10 and applying pressure, the outer cylinder membrane 1 is pressed against the uneven portion 12. The cylindrical structure 10 is engaged and fixed to the lightweight joint 11 by this frictional force. This lightweight fitting Various forces such as tension, compression, bending, shearing, and torsion are applied to the cylindrical structure by hand11. can be communicated. In addition, as shown in FIG. 3, the connection between the end of the cylindrical structure 10 and the lightweight joint 11 is The gap is filled with a packing material 14 such as urethane rubber. In addition, lightweight fittings 11 The material is not limited to aluminum, but also synthetic resin and Kepler (aramid). (made of fiber material and synthetic resin) may also be used.

The type lightweight joint 15 has, for example, a through hole 16 penetrated in the vertical direction and a side hole opened laterally. 17, each hole 16, 17 has the structure of the cylindrical opening 13, and the uneven portion 12 is formed. According to this, the cylindrical structures 10 can be easily connected to each other. Wear. In this example, a T-shaped one is shown, but a cross-shaped one or one with multiple connections is also available. A large number of cylindrical structures 10 may be connected to each other by, for example, .

Figure 6 shows a schematic perspective view of the balloon, and as shown in Figures 5 and 6, The skeleton part of the boat 20 and the balloon 30 has a cylindrical structure 10 extending in the circumferential direction, which is duplicated in the longitudinal direction. It is formed by arranging several. Then, the pressure inside the inner cylinder membrane of these cylindrical structures 10 is An airship 20 formed by these cylindrical structures 10 by being raised appropriately Moreover, the balloon 30 can maintain its shape even if the pressure inside the balloon 30 is brought to a near-vacuum state. did Therefore, it is necessary to exhaust the gas inside the airship 20 and the balloon 30 using a vacuum pump or the like. This allows easy adjustment of buoyancy and significantly reduces the amount of helium required to obtain buoyancy. At the same time, it is possible to realize an airship 20 and a balloon 30 with easy buoyancy adjustment.
【００１２】 図７は本考案の筒状構造体を用いたドームを示す概略斜視図で、図７に示すよ うに、ドーム40の骨格部は周方向に延びる筒状構造体10を高さ方向に複数配設し て形成されている。これによれば、従来のように複雑なトラス構造などを用いる ことなく、構造を単純化でき、設計面での制約が大幅に減少し、建設の際の工期 を大幅に短縮でき、建設作業の安全性も向上する。0012 FIG. 7 is a schematic perspective view showing a dome using the cylindrical structure of the present invention, as shown in FIG. In other words, the skeleton of the dome 40 has a plurality of cylindrical structures 10 extending in the circumferential direction arranged in the height direction. It is formed by According to this, using a complex truss structure as in the past The structure can be simplified, design constraints are significantly reduced, and the construction period is reduced. This will significantly shorten the time required and improve the safety of construction work.
【００１３】 図８は本考案の筒状構造体を用いた宇宙基地を示す概略斜視図で、図８および 図９に示すように、宇宙基地50の骨格部は縦横および斜め方向に延びる筒状構造 体10を複数配設して形成されている。また、図10に示すように、受信発信部51の 骨格部も周方向および放射方向に延びる筒状構造体10を複数配設して形成されて いる。これによれば、宇宙基地50の骨格部を小さく折り畳んでロケット内に収納 でき、軽量であるため、輸送エネルギーの低減を図れ、現場で筒状構造体10に気 体を流入させることにより宇宙基地50の構築を短時間で容易にできる。[0013] FIG. 8 is a schematic perspective view showing a space base using the cylindrical structure of the present invention. As shown in Figure 9, the skeleton of the space station 50 has a cylindrical structure extending vertically, horizontally and diagonally. It is formed by arranging a plurality of bodies 10. In addition, as shown in FIG. The skeleton part is also formed by arranging a plurality of cylindrical structures 10 extending in the circumferential direction and the radial direction. There is. According to this, the skeleton of Space Station 50 can be folded into a small size and stored inside the rocket. Because it is lightweight and can reduce transportation energy, it is easy to handle the cylindrical structure 10 at the site. The influx of bodies allows for the construction of a space base 50 in a short period of time.
【００１４】 さらに、図11は本考案の筒状構造体を用いた簡易橋を示す概略斜視図である。 この簡易橋60は、長手方向に延びる筒状構造体10を複数配設して形成されている 。これによれば、取り扱いが容易で、一人でも取り扱え、筒状構造体10への空気 注入により速やかに所定の強度を有する部材を構成できるため、組立，解体を迅 速に行え、コンパクトな状態で輸送できる。また、簡易橋60は軽量であるため、 いかだとして用いることができ、図12に示すように、幅方向に延びる筒状構造体 10を複数配設していかだ70を形成してもよい。[0014] Furthermore, FIG. 11 is a schematic perspective view showing a simple bridge using the cylindrical structure of the present invention. This simple bridge 60 is formed by arranging a plurality of cylindrical structures 10 extending in the longitudinal direction. . According to this, it is easy to handle, even one person can handle it, and the air to the cylindrical structure 10 is By injection, it is possible to quickly construct components with a specified strength, allowing for quick assembly and disassembly. It can be carried out quickly and transported in a compact state. In addition, since the simple bridge 60 is lightweight, A cylindrical structure that can be used as a raft and extends in the width direction, as shown in Figure 12. 10 may be arranged to form the raft 70.
【００１５】 また、図13〜図15に示すように、骨格部および上面部に筒状構造体10を複数並 べて配設して簡易橋80を形成してもよく、この簡易橋80を、図16の(a) 〜(d) に 示すように車載することもできる。これによれば、構成部材としての筒状構造体 10が軽量であり、空気を抜いた状態で非常に小さくできるため、搭載用の車両81 を、従来の無軌道車などを用いることなく、小回りがきき、使い勝手のよい装輪 車で対応できる。そして、筒状構造体10への空気注入により速やかに所定の強度 を有する部材を構成できるため、簡易橋80の架設、撤収を迅速に行える。[0015] In addition, as shown in FIGS. 13 to 15, a plurality of cylindrical structures 10 are arranged in parallel on the skeleton and the upper surface. A simple bridge 80 may be formed by arranging all It can also be mounted on a car as shown. According to this, a cylindrical structure as a component 10 is lightweight and can be very small when deflated, making it suitable for mounting on vehicles81 , a wheeled vehicle that is easy to turn and easy to use, without using conventional trackless vehicles. This can be done by car. Then, by injecting air into the cylindrical structure 10, the predetermined strength is quickly achieved. Since it is possible to construct a member having the following structure, the simple bridge 80 can be quickly erected and dismantled.
【００１６】 また、筒状構造体10をエアジャッキ90として用いてもよい。すなわち図17の(a ) ，(b) に示すように、脱輪やはまり込み状態の車輪90の下に、空気を抜いた状 態の筒状構造体10を挟み込む。この際に、筒状構造体10を薄く押し潰した状態に できるため、車輪91とはまり込み箇所との間にこの筒状構造体10を容易に挟み込 むことができる。この後、図17の(c) に示すように、筒状構造体10を挟み込んだ 状態で、この筒状構造体10に注入口２ａから空気を注入する。この際の空気圧は ４kg・f/cm2 以下で十分であるので、手押しポンプで注入することが可能である 。空気注入後には、エアジャッキ90としての筒状構造体10は十分に強い構造の円 筒形状となるため、この上を車輌で走行することが可能であり、容易に車輌を走 行・脱出できる。Further, the cylindrical structure 10 may be used as an air jack 90. That is, as shown in FIGS. 17(a) and 17(b), the deflated cylindrical structure 10 is sandwiched under the wheel 90 that has fallen off or is stuck. At this time, since the cylindrical structure 10 can be crushed thinly, the cylindrical structure 10 can be easily sandwiched between the wheel 91 and the fitting location. Thereafter, as shown in FIG. 17(c), air is injected into the cylindrical structure 10 from the injection port 2a with the cylindrical structure 10 sandwiched therebetween. Since the air pressure at this time is sufficient to be 4 kg·f/cm 2 or less, it is possible to inject with a hand pump. After the air is injected, the cylindrical structure 10 serving as the air jack 90 has a sufficiently strong cylindrical shape, so that a vehicle can run on it, and the vehicle can easily run and escape.
【００１７】 つまり、従来では、脱輪やはまり込み状態からの車輪の脱出は人力で車輌を持 ち上げる方法や、車輪の下に土砂、石、木ぎれなどを詰め込む方法しかなく、ま た、従来のジャッキでは、まず車輪の下に挟み込むことが困難で、例え、ジャッ キを挟み込んで持ち上げることができたとしても、そのジャッキを支えとして使 用した状態で車輌を走行させて車輪を脱出させることは危険過ぎた。このため、 従来のジャッキは脱出に利用できなかったが、本実施例のエアジャッキ90によれ ば、車輌を容易かつ迅速に、しかも少ない労力で走行・脱出できる。[0017] In other words, in the past, the only way to get a wheel out of a derailed or stuck state was to manually hold the vehicle. The only options are to hoist it up, or to stuff dirt, stones, wood chips, etc. under the wheels. In addition, with conventional jacks, it is difficult to clip them under the wheels; Even if you can lift the jack by holding it in place, do not use the jack as a support. It was too dangerous to drive the vehicle and try to remove the wheels while the wheels were in use. For this reason, Conventional jacks could not be used for escape, but with the air jack 90 of this example, If so, the vehicle can be easily and quickly driven and escaped with less effort.
【００１８】 なお、脱出の際の走行をさらに容易にするために、図18に示すように、複数の 筒状構造体10を連結した構造のエアジャッキ92を用いることも可能である。[0018] In addition, in order to make it easier to run when escaping, there are multiple It is also possible to use an air jack 92 having a structure in which the cylindrical structures 10 are connected.
【００１９】[0019]
