この考案は浮体構造物、とくに大型の浮体構造物に関す
る。[Detailed Description of the Invention] This invention relates to a floating structure, particularly a large floating structure.
海面に設けられる浮体構造物、とくに大型の浮体構造物
においては、波浪の影響を軽減させる必要がある。Floating structures installed on the sea surface, especially large floating structures, need to reduce the influence of waves.
構造物本体の下面に多数の筒状の支持浮体を設け、各支
持浮体の二部外のみが海水中に没して、この部分に作用

所に分散した水平断面積の小さい支持浮体で波浪を受け

、支持浮体に及ぼす波浪の影響をさらに軽減させること
が望１れている。A large number of cylindrical support floats are installed on the underside of the structure, and only the outer two parts of each support float are submerged in seawater, so that the entire weight is supported only by the buoyancy acting on these parts, and the structure is installed at multiple locations. Although the effects of waves can be reduced by being exposed to the waves with dispersed support floating bodies with small horizontal cross-sectional areas, it is desired to further reduce the influence of waves on the support floating bodies.
この考案の目的は、波浪の影響を受けにくぃ浮体構造物
を提供することにある。The purpose of this invention is to provide a floating structure that is not affected by waves.
この考案による支持浮体は、構造物本体の下面に複数個

常時には浮力タンクが海底に沈められるようになされて
いるものである。The supporting floating body according to this invention has a plurality of supporting floating bodies provided on the underside of the structure body, and only a part of each supporting floating body is submerged in seawater, so that the entire weight is supported only by the buoyancy force acting on this part. In this floating structure, a comb-shaped fresh liquid tank with a buoyancy tank at the bottom that can adjust the amount of air is swingably attached to the outer periphery of the structure body, and the amount of air in the buoyancy tank is adjusted. Normally, the buoyancy tank is submerged in seawater and the upper side of the fresh liquid tank protrudes above the sea surface, but in the event of an abnormality, the buoyancy tank is sunk to the seabed.
この考案によれば、構造物本体の外周に設けられた櫛状
の清液槽によって波浪が消波されるため、支持浮体に伝
わる波浪が非常に小さくなり、波浪の影響が著しく軽減
される。According to this invention, waves are dissipated by the comb-shaped fresh liquid tank provided on the outer periphery of the structure body, so the waves transmitted to the supporting floating body become extremely small, and the influence of waves is significantly reduced.
また、通常は浮力タンクが海水中に没して清液槽の上側
が海面上に突出しているので、浮力タンクが波浪の影響
を受けにくく、しかも波浪による上下方向の力はもちろ
ん水平方向の力を受けても清液槽が揺動し、清液槽が揺
動するときに海水中にある浮力タンクが抵抗になって波
浪のエネルギが吸収される。In addition, since the buoyancy tank is usually submerged in seawater and the upper side of the fresh liquid tank protrudes above the sea surface, the buoyancy tank is less susceptible to the effects of waves, and it is not only affected by waves in the vertical direction but also by horizontal forces. The fresh liquid tank oscillates even when exposed to waves, and when the fresh liquid tank oscillates, the buoyancy tank in the seawater acts as a resistance and absorbs the energy of the waves.
このため、波浪による上下方向の力はもちろん水平方向
の力も構造物本体に伝わりにくくなり、その結果、構造
物本体に対する波浪の影響が著しく軽減される。For this reason, not only vertical forces due to waves but also horizontal forces are less likely to be transmitted to the structure body, and as a result, the influence of waves on the structure body is significantly reduced.
さらに、強風等の異常時には、浮力タンクを海底に沈め
ることによって水平方向の移動に対する抵抗力を増大さ
せることができるため、ドルフィン等に加わる荷重を軽
減できるという効果を素する。Furthermore, in the event of an abnormality such as strong winds, the resistance to horizontal movement can be increased by sinking the buoyancy tank to the seabed, which has the effect of reducing the load applied to the dolphin or the like.
以下図面を参照してこの考案の実施例を説明するＯ
浮体構造物は、平面から見て長方形状の構造物本体１と
、その下面に固定された多数の円筒状の支持浮体２とを
備え、構造物本体１外周の２辺に櫛状の清液槽３が揺動
自在に取付けられている。Embodiments of this invention will be described below with reference to the drawings. The floating structure includes a structure main body 1 that is rectangular in plan view and a large number of cylindrical supporting floats 2 fixed to the lower surface of the structure main body 1. A comb-shaped fresh liquid tank 3 is swingably attached to two sides of the outer periphery of the structure main body 1.
浮体構造物は、構造物本体１が水平になるように海面に
浮かべられ、ドルフィン（図示時）等に係留されており
、各支持浮体２の一部分が海水中に没して、この部分に
作用する浮力によって全重量が支えられるようになされ
ている。The floating structure is floated on the sea surface so that the structure body 1 is horizontal and moored to a dolphin (as shown), etc., and a part of each supporting floating structure 2 is submerged in the seawater and acts on this part. The entire weight is supported by the buoyancy.
清液槽３は、軸心が水平になるように配置された円筒状
の細長い浮力タンク４と、浮力タンク４の上部に固定さ
れた枠体５との間に、断面三角形の多数の棒材６が二列
に設げらｋてなるものである。The fresh liquid tank 3 has a cylindrical elongated buoyancy tank 4 arranged so that its axis is horizontal, and a frame 5 fixed to the top of the buoyancy tank 4. 6 are arranged in two rows.
棒材６は各列とも同じピッチで、しかも相互に半ピツチ
ずれた位置に配置されている。The bars 6 are arranged at the same pitch in each row and at positions shifted by half a pitch from each other.
浮力タンク４は、下部に断面Ｖ字形の係止部材７を有し
、外周に固定された多数の連結部材８によって構造物本
体１の側面に取り付けられている。The buoyancy tank 4 has a locking member 7 with a V-shaped cross section at its lower part, and is attached to the side surface of the structure main body 1 by a number of connecting members 8 fixed to the outer periphery.
また、枠体５の上部と連結部材８との間には多数の補助
部材９が設けられている。Further, a large number of auxiliary members 9 are provided between the upper part of the frame 5 and the connecting member 8.
浮力タンク４は図示しない装置により内部の空気量の調
節ができ、通常は、浮力タンク４が完全に海水中に没し
て清液槽３の上側が海面上に突出するようになされてい
る（第１図の実線）。The amount of air inside the buoyancy tank 4 can be adjusted by a device (not shown), and normally the buoyancy tank 4 is completely submerged in seawater and the upper side of the fresh liquid tank 3 protrudes above the sea surface. (solid line in Figure 1).
波浪は清液槽３によって減衰され、清液槽３は波浪によ
って上下動するが、構造物本体１に揺動自在に取付けら
れているので、この動きは構造物本体１に伝わらない。Waves are attenuated by the fresh liquid tank 3, and although the clear liquid tank 3 moves up and down due to the waves, this movement is not transmitted to the structure body 1 because it is swingably attached to the structure body 1.
さらに、波浪は多数の連結部材８によっても減衰される
ので、浮体構造物は波浪の影響を受けにくくなる。Furthermore, since waves are also attenuated by the large number of connecting members 8, the floating structure becomes less susceptible to the effects of waves.
また、浮力タンク４が海水中に没して清液槽３の上側が
海面上に突出しているので、浮力タンク４が波の影響を
受けにくく、しかも波浪による上下方向の力はもちろん
水平方向の力を受けても清液槽３が揺動し、清液槽３が
揺動するときに海水中にある浮力タンク４が抵抗になっ
て波浪のエネルギが吸収される。In addition, since the buoyancy tank 4 is submerged in seawater and the upper side of the fresh liquid tank 3 protrudes above the sea surface, the buoyancy tank 4 is less susceptible to the effects of waves, and moreover, it is not affected by the vertical force caused by waves, but also by the horizontal force. Even when subjected to force, the fresh liquid tank 3 swings, and when the fresh liquid tank 3 swings, the buoyancy tank 4 in the seawater becomes a resistance and the energy of waves is absorbed.
このため、波浪による上下方向の力はもちろん水平方向
の力も構造物本体１に伝わりにくくなり、その結果、構
造物本体１に対する波浪の影響が著しく軽減される。Therefore, not only the vertical force due to waves but also the horizontal force is difficult to be transmitted to the structure main body 1, and as a result, the influence of waves on the structure main body 1 is significantly reduced.
強風等の異常時には、浮力タンク４内に海水を注入して
浮カタ／り４を清液槽３とともに海底に沈めてし渣う（
第１図の鎖線）。In the event of an abnormality such as strong winds, seawater is injected into the buoyancy tank 4 and the floating float 4 is sunk to the seabed together with the fresh liquid tank 3.
(dashed line in Figure 1).
これにより浮体構造物の水平方向の移動に対する抵抗が
増大するので、ドルフィン等に加わる力が軽減される。This increases the resistance to horizontal movement of the floating structure, thereby reducing the force applied to the dolphin and the like.

The buoyancy tank 4 serves to protect the buoyancy tank 4 and increase resistance to horizontal movement by being caught on the seabed, and may be provided integrally over the entire length of the buoyancy tank 4 as in this embodiment, or It may be provided separately into a plurality of pieces, and its shape is also arbitrary.
