More specifically, the present invention relates to an improvement in the structure of a pressure resistant tube having a strength corresponding to the flow pressure of a fluid flowing inside.
（従来の技術とその問題点） 従来、耐圧管としては、例えば実開昭58-12780号公報に
記載されるもののように、チューブの外周面に、少なく
とも一方向に延伸されたプラスチックテープを所定の角
度で螺旋状に捲回取付けしてなるものが知られている。(Prior Art and Problems Thereof) Conventionally, as a pressure resistant tube, for example, as described in Japanese Utility Model Laid-Open No. 58-12780, a plastic tape stretched in at least one direction is predetermined on the outer peripheral surface of the tube. It is known that a spirally wound attachment is made at an angle of.

耐圧管を得るのが困難であり、用途範囲が限定されると
いう問題がある。However, in this conventional pressure-resistant tube structure, the plastic tape itself functions as a pressure-resistant structure, so the pressure-resistant strength is not sufficient, and in order to obtain the necessary pressure-resistant strength, the tape resin material and Since the draw ratio and the like at the time of tape molding must be selected one by one, it is difficult to obtain a pressure resistant tube having a desired pressure resistance, and there is a problem that the range of applications is limited.
（考案の目的） 本考案は斯る問題点を解決するためになされたものであ

構成を採用する。(Structure of the Invention) In order to achieve the above object, the present invention spirally attaches a synthetic resin tape formed by mixing a large number of continuous reinforcing threads into the inside of the tape in a spiral shape on the outer peripheral surface of the tube. The configuration will be adopted.

（実施例） 以下、本考案の係る耐圧管の実施例を図面に基づいて説
明する。(Embodiment) An embodiment of the pressure resistant tube according to the present invention will be described below with reference to the drawings.
第１図、第２図に示すように、この実施例では、多数の
強化糸１を混入した構造の合成樹脂テープ２をチューブ
３の外周面に螺旋状に捲回取付けし、更に同じ構造の合
成樹脂テープ４を前記合成樹脂テープ２の上から逆方向
へ螺旋状に捲回取付けしている。As shown in FIGS. 1 and 2, in this embodiment, a synthetic resin tape 2 having a structure in which a large number of reinforcing yarns 1 are mixed is spirally attached to the outer peripheral surface of a tube 3, and the same structure is used. The synthetic resin tape 4 is spirally attached in a reverse direction from above the synthetic resin tape 2.

いが、合成樹脂テープ2,4の取付性から外周面に凹凸条
が形成されず平滑であることが好ましい。The tube 3 is made of a synthetic resin material or the like, and may be a single layer as shown in the drawing, or may be a multilayer. In addition, it does not matter if a reinforcing structure such as embedding a reinforcing thread is already adopted inside, but it should be smooth with no uneven lines formed on the outer peripheral surface due to the attachability of the synthetic resin tapes 2 and 4. Is preferred.

片面に接着剤を塗布しておけば、捲回取付けが容易とな

混入は、合成樹脂テープ2,4の成形時に強化系１を一体
的に埋め込む等の混入手段が採られる。The synthetic resin tapes 2 and 4 are made of, for example, PVC resin by extrusion molding or the like. If the adhesive is applied to one surface of each of the synthetic resin tapes 2 and 4, there is an advantage that the winding attachment becomes easy. The reinforced yarn 1 is mixed into the synthetic resin tapes 2 and 4 by a mixing means such as burying the reinforced system 1 integrally at the time of molding the synthetic resin tapes 2 and 4.
強化糸１は、合成樹脂繊維、天然繊維、金属線等任意の
材質で差支えないものである。この強化糸１の合成樹脂
テープ2,4への混入構造は、一方向へ揃えて並列にする
とか、格子状、ダイア状に編成する等、所望の耐圧性に
応じて任意に選択できる。The reinforcing yarn 1 may be made of any material such as synthetic resin fiber, natural fiber, and metal wire. The structure in which the reinforcing yarn 1 is mixed with the synthetic resin tapes 2 and 4 can be arbitrarily selected according to the desired pressure resistance, such as arranging in parallel in one direction and knitting in a lattice shape or a diamond shape.

捲回取付けにおいては、強化糸１が合成樹脂テープ2,4
の柔軟性を規制するため、捲回中に合成樹脂テープ2,4
が捩れたりすることがなく、捲回操作が容易である。When the synthetic resin tapes 2 and 4 are wound and attached, as described above, when the adhesive is not applied, the adhesive is applied to the outer peripheral surface of the tube 3 and the outside of the already wound synthetic resin tape 2. It may be carried out, or may be coated with an adhesive resin and fixed after winding and mounting. Further, in the case of partially reinforcing the compressive strength of the tube 3, it is possible to adopt a means of fixing the wound end portion with a stopper without using an adhesive. In addition, in this winding attachment, the reinforcing yarn 1 is made of synthetic resin tapes 2, 4
Plastic tape 2,4 during winding to control the flexibility of
It is not twisted and the winding operation is easy.

合成樹脂テープ2,4の作用を補完することから、かなり
高い耐圧強度が具備されることになる。In the pressure resistant tube with such a structure, the synthetic resin tape 2,
Since the wall thickness of the tube 3 is increased by 4, and the radial extension of the tube 3 is restricted by the spiral winding of the synthetic resin tapes 2 and 4, the compressive strength is improved. Since the reinforcing yarn 1 regulates the soft extensibility of the synthetic resin tapes 2 and 4 and complements the action of such synthetic resin tapes 2 and 4, a considerably high pressure resistance is provided.
以上、図示実施例の他に、合成樹脂テープ2,4の捲回取
付けを一層のみに、また、三層以上とする実施例とする
こともできる。As described above, in addition to the illustrated embodiment, it is possible to adopt an embodiment in which the synthetic resin tapes 2 and 4 are wound and attached only in one layer or in three or more layers.

が要求される広範な分野での利用が可能となる。(Effect of the Invention) As described above, in the pressure resistant tube according to the present invention, a large number of reinforcing threads mixed in the synthetic resin tape regulate the flexibility of the synthetic resin tape itself, and the synthetic resin tape is attached to the outer circumference of the tube. Since expansion in the radial direction after the spiral attachment to the surface is restricted, the pressure resistance becomes good, and it can be used in a wide range of fields where high pressure resistance is required.
また、合成樹脂テープに混入する強化糸の本数や混入構
造を自由に選択して耐圧強度を適宜調整することがで
き、所望の耐圧強度を有する耐圧管の製造を容易に行な
うことができる。Further, the pressure resistance can be appropriately adjusted by freely selecting the number of reinforcing yarns mixed in the synthetic resin tape and the mixing structure, and the pressure resistant tube having a desired pressure resistance can be easily manufactured.
更に、強化糸を合成樹脂テープに混入してチューブの外

って保護され、その強化糸を摩耗、損傷等から保護する
ために更に合成樹脂テープの表面側に保護層を被覆する
必要がなく、構造簡単な耐圧管とすることができる。Further, since the reinforcing yarn is mixed with the synthetic resin tape and wound around the outer peripheral surface of the tube, the reinforcing yarn is protected by the synthetic resin, and the synthetic resin is further protected to protect the reinforcing yarn from abrasion and damage. Since it is not necessary to cover the protective layer on the surface side of the tape, a pressure resistant tube having a simple structure can be obtained.
しかも、強化糸による合成樹脂テープの柔軟性規制によ
り工作作業が容易となり、耐圧管自体の製造が容易とな
る。Moreover, the workability is facilitated by the restriction of the flexibility of the synthetic resin tape by the reinforcing yarn, and the pressure resistant tube itself is easily manufactured.
