この発明は、各種の適性を有するいけす装置用
枠部材の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in frame members for cage apparatuses having various suitability.
海中を網で囲い、その内部における魚介類の養

けす装置の容量、とくに平面投影面積の大きいい
けす装置を必要とする。 A cage device that surrounds the sea with a net and is used for cultivating or capturing and housing fish and shellfish inside the net has a frame that floats on the sea surface to suspend and support the net.To improve the efficiency of aquaculture or capture and transportation, A cage device with a large capacity, especially a planar projected area, is required.

枠体を形成する補強ホースのキンクが発生してそ
の破損をきたす問題があつた。 However, for this purpose, multiple reinforcing hoses with embedded tensile reinforcement layers were interconnected with direct joints, and due to the curvature of the reinforcing hoses, the planar projected shape was approximately circular and the diameter was 30 to 100 m. When constructing a large-scale cage device, the capacity can be increased by 6 to 70 times compared to a cage device constructed with a rigid frame made of steel pipes or other materials. When towing a cage frame, when a strong current from the open ocean acts on the frame, a strong external force from a specific direction acts on the cage frame, forcing it into a curved initial position due to the straight joint. There was a problem in that the reinforcing hose that had been inserted into the cage returned to its straight state and a crease with a small radius of curvature was formed near the direct joint, causing a kink in the reinforcing hose that formed the cage frame and causing its breakage.
そこで出願人は先に、曵航や潮流に十分耐え得

A locking portion 5 of a mooring line 4 is provided at the bent joint 2, and a net 6 is suspended from the cage frame 3.

生じない程度の剛性を有するとともに、折れる

通常の潮流および曵航からは予期し得ない程
大きな外力の作用によつて仮りに折れたとして

維持する形状保持性をもたらすものである。 Based on this knowledge, the present invention fully satisfies all of the above conditions required for a cage frame by providing a floating frame member that has all of these characteristics. The elastic body that forms the main part of the chamber is made of rubber or rubber-like elastic body, and is reinforced with organic or inorganic fiber cords to provide resilience, and the outer diameter of this reinforced elastic body is approximately 279.4 ~ Approximately 609.6mm
(11 to 24 inches) to provide the necessary excess buoyancy, and the wall thickness of this reinforcing elastic body, which is assumed to be filled with gas such as nitrogen or air, to be approximately 12.7 to 24 inches.
50.8 mm (1/2 to 2 inches) provides sufficient fender, and in addition to this, the reinforcing elastic body itself has an E/I of 100 to 3000.
By selecting the number and angle of the layers of the elastic member and fiber cord so that the weight of the reinforcing elastic body is 0.1 to 20 Kg/cm 2 so that the The E.I.
10 3 to 10 4 Kg-m 2 to provide sufficiently satisfactory wave resistance, stiffness, and kink resistance, and furthermore, the ratio of circumferential stress to axial stress generated when the reinforcing elastic body is filled with internal pressure. By setting the value to 1.5 to 2.5, it is possible to maintain a constant length and diameter at all times.
ここにおいて補強弾性体の外径を約279.4〜約
609.6mm（11〜24インチ）とするのは、約279.4mm
未満では50Kg／ｍの余剰浮力をもたらすことがで

て過剰設計となるからである。 Here, the outer diameter of the reinforcing elastic body is approximately 279.4 to approximately
609.6mm (11-24 inches) is approximately 279.4mm
If it is less than 50Kg/m, it will not be possible to provide a surplus buoyancy of 50Kg/m, while if it is greater than about 609.6mm,
This is because the design would be excessive, exceeding the requirements described above. In addition, the thickness of the reinforcing elastic body should be adjusted to approximately 12.7 to approximately
The reason for choosing 50.8 mm (1/2 to 2 inches) is not only for fender properties but also for the E/I value of the reinforcing elastic body itself and the stress ratio when filling it with internal pressure.
This is because if it is less than 12.7 mm, it will be difficult to maintain kink resistance, and if it is larger than about 50.8 mm, the design will be excessive compared to the required conditions.

性体自身のＥ・Ｉ値を変更した場合には、図示の
各曲線はそのＥ・Ｉの増加につれて勾配が強くな
ることが確認されている。 In addition, the fiber cord used here as a reinforcing material is because the fiber cord, which is made of twisted wires of organic, inorganic, or metal fibers, does not undergo fracture plastic deformation even if the reinforcing elastic body breaks, and has sufficient elasticity. This is because it has a restoring force, and the filling pressure is limited to 0.1 to 20 Kg/cm 2 as shown in Figure 2.
As is clear from the graph showing the relationship between curvature, bending moment, and E/I, as an example of the reinforcing elastic body, the outer diameter is 438 mm, the wall thickness is 24 mm, and the inner rubber + 8 cord layers + intermediate rubber + 4 cord layers are used. In a reinforcing elastic body with + jacket rubber and E・I = 1000 Kgm 2 , the E・I after filling with nitrogen gas as an example of gas is 10 3 to 10 4 Kg that satisfies various performances.
-m 2 , and a value of 0.1 here means that some amount of nitrogen gas is filled. It has been confirmed that when the E/I value of the reinforcing elastic body itself is changed, the slope of each curve shown in the figure becomes stronger as the E/I increases.
従つて、気体充填後における所要のＥ・Ｉ値を
もたらすためには、充填圧力のみならず補強弾性
体自身のＥ・Ｉ値をも適宜に選択することが必要
になるが、ここでは、そのＥ・Ｉ値が100Kg−m2
未満のときには内圧を増してもゴム枠構造の安全

剛性が得られず、また3000Kg−m2より大きいとき
は内圧を充填する必要を欠き、内圧充填による本
システムの経済的メリツトを生かせなくなるか
ら、100〜3000Kg−m2の範囲としている。 Therefore, in order to obtain the required E・I value after gas filling, it is necessary to appropriately select not only the filling pressure but also the E・I value of the reinforcing elastic body itself. E・I value is 100Kg−m 2
If it is less than 3000Kg-m2, even if the internal pressure is increased, the appropriate rigidity required within the pressure resistance range considering the safety of the rubber frame structure cannot be obtained, and if it is greater than 3000Kg- m2 , there is no need to fill the internal pressure. Since the economical benefits of this system due to internal pressure filling cannot be utilized, it is set in the range of 100 to 3000 kg- m2 .

I is 100 to 3000 Kg- m2 , the internal pressure of filling the reinforcing elastic body is 0.1 to 20 Kg/ cm2 , and the ratio of the circumferential stress to the axial stress generated in the reinforcing elastic body when filling the internal pressure is 1.5 to 2.5. This provides sufficient wave handling properties, rigidity, and kink resistance, as well as extra buoyancy, fenderability, and shape retention, making it possible to construct large-scale cage equipment and use it in the open ocean. This has the great practical benefit of being able to be towed as well.
