Description

本願発明は、複数の単位浮体を水上にて平面状に組み立てて、水上作業における組立式作業台船として使用される浮体構造体に関するものである。 The present invention relates to a floating body structure that is used as an assembling work table ship in a water work by assembling a plurality of unit floating bodies in a planar shape on the water.

このような浮体構造体は、海上作業のみにおいて使用されるものではなく、河川とか湖沼等の内水面での作業においても使用されるものであることから、これを単体構造としたのでは陸上輸送ができないことから、通常、トラックにて搬送可能な大きさをもつ単位浮体を複数製作し、これら複数の単位浮体をそれぞれ作業場所まで輸送して作業水面に浮かべるとともに、浮かべた状態で、複数の単位浮体を順次平面方向に連結して組み立てて、水上作業における組立式作業台船として使用するようになっている。 Such floating structures are not only used for offshore work but also used for work on inland waters such as rivers and lakes. Therefore, normally, a plurality of unit floats with a size that can be transported by truck are manufactured, and each of these unit floats is transported to the work place and floated on the working water surface. Unit floating bodies are sequentially connected in a planar direction and assembled to be used as an assembly work platform ship in water work.

この場合における各単位浮体相互間の連結構造としては、従来から種々の構造が提案されている（例えば、特許文献１、特許文献２参照）。 In this case, various structures have been conventionally proposed as a connection structure between the unit floating bodies (see, for example, Patent Document 1 and Patent Document 2).

特許文献１に示されるものは、水上に浮かべられた要素浮体間を連結するに際して、該各要素浮体の幅方向中央部同士を、相対回転を許容する回転継手で連結するとともに、該要素浮体の幅方向両側部にそれぞれ折曲可能なロッドを備えた引張機構で連結するようにしている。 When connecting the element floating bodies floated on water, the one shown in Patent Document 1 connects the center portions in the width direction of each element floating body with a rotary joint that allows relative rotation. It is made to connect with the tension | tensile_strength mechanism provided with the rod which can be bent in the width direction both sides, respectively.

特許文献２に示されるものは、浮体の側面に、該側面から側方へ延出する連結プレートを浮体の上下方向に所定間隔をもって一対配置するとともに、これら上下一対の連結プレートを、浮体の側面の幅方向へ所定間隔で複数配置している。そして、浮体同士の連結に際しては、二つの浮体を、その側面同士を対向させるように位置させ、一方の浮体側の各連結プレートと他方の浮体側の各連結プレートをそれぞれ重合させる。この浮体の上部側において重合した一対の連結プレートと、下部側において重合した一対の連結プレートを、上方側から挿通される単一の連結ピンによって同時に連結するようにしている。 In Patent Document 2, a pair of connecting plates extending laterally from the side surface is arranged on the side surface of the floating body at a predetermined interval in the vertical direction of the floating body, and the pair of upper and lower connecting plates are arranged on the side surface of the floating body. A plurality of them are arranged at predetermined intervals in the width direction. When the floating bodies are connected to each other, the two floating bodies are positioned so that the side surfaces thereof face each other, and the connection plates on one floating body side and the connection plates on the other floating body side are superposed. A pair of connecting plates superposed on the upper side of the floating body and a pair of connecting plates superposed on the lower side are simultaneously connected by a single connecting pin inserted from above.

ところが、特許文献１に示される連結構造においては、その構造が複雑で且つ高価であって、汎用性という点において問題がある。また、回転継手で連結された一対の要素浮体間における所定範囲内の回転動作を許容する必要上、これら一対の要素浮体間の間隔が比較的大きく設定されているところから、この要素浮体間の隙間部分に作業用機器等が落ち込む可能性があり、作業の安全性という点で改善の余地がある。 However, the connection structure disclosed in Patent Document 1 is complicated and expensive, and has a problem in terms of versatility. In addition, since it is necessary to allow a rotational movement within a predetermined range between a pair of element floats connected by a rotary joint, the distance between the pair of element floats is set to be relatively large. There is a possibility that work equipment or the like may fall into the gap, and there is room for improvement in terms of work safety.

また、特許文献２に示される連結構造においては、浮体側面に設けられた連結プレートが全て該側面から側方へ延出する雄型構成であることから、一方の浮体の連結プレートと他方の浮体の連結プレートを重合させて連結ピンで連結した場合、該各連結プレートの先端が他方の浮体の側面と干渉するのを回避する必要上、連結された一対の浮体の側面相互間には所定の隙間が確保されている。そして、この浮体側面間の隙間が浮体上面に現れるのを回避すべく、上面板の周縁を側面より外方へ延出させている。 Moreover, in the connection structure shown by patent document 2, since all the connection plates provided in the floating body side surface are the male type structure extended from this side surface to the side, the connection plate of one floating body and the other floating body When the connecting plates are overlapped and connected with connecting pins, it is necessary to avoid the front end of each connecting plate from interfering with the side surface of the other floating body. A gap is secured. And in order to avoid that the clearance gap between this floating body side surface appears on a floating body upper surface, the peripheral edge of the upper surface board is extended outward from the side surface.

ところが、このように浮体上面板を側面から外方へ延出させた場合、浮体の外形寸法、即ち、浮体をトラック搬送する場合の法定の限界寸法が上面板の寸法によって規定されることから、浮体の浮力確保に寄与しない無駄な幅寸法が発生し、その結果、外形寸法の割には浮力が小さいという浮体性能上の問題が発生することになる。 However, when the floating body upper surface plate is extended outward from the side surface in this way, the outer dimensions of the floating body, that is, the legal limit dimensions when the floating body is transported by the truck, are defined by the dimensions of the upper surface plate. A useless width dimension that does not contribute to securing the buoyancy of the floating body is generated, and as a result, a problem in floating body performance is generated in that the buoyancy is small for the outer dimension.

また、この連結構造では、単一の連結ピンを、上側の一対の連結プレートと下側の一対の連結プレートに対して上方から嵌挿する構成であることから、浮体同士の連結及び分離作業時には、一旦、連結ピンを完全に取外す必要があることから、作業が煩雑で、且つ作業性が悪く作業の迅速性が損なわれるという問題があった。 Moreover, in this connection structure, since it is the structure which inserts a single connection pin from upper direction with respect to a pair of upper connection plate and a pair of lower connection plate, at the time of connection and isolation | separation work of floating bodies Since it is necessary to completely remove the connecting pin once, there is a problem that the work is complicated and the workability is poor and the speed of the work is impaired.

そこで本願発明は、高い浮力性能及び作業上の安全性を確保するとともに、連結・分離作業における作業性を高めて迅速且つ確実な作業を可能とする浮体構造体を提供することを目的としてなされたものである。 Therefore, the present invention has been made with the object of providing a floating structure that ensures high buoyancy performance and work safety, and improves workability in connection / separation work to enable quick and reliable work. Is.

（ａ）本願の第１の発明に係る浮体構造体によれば、上記単位浮体２の側面に設けられた第１連結部Ｐが該側面から外方へ延出した上下一対の上側雄型連結具３と下側雄型連結具４で構成され、また上記第２連結部Ｑが該側面から内部側へ陥没した上下一対の上側雌型連結具６と下側雌型連結具７で構成されているので、
（ａ−１）これら雄型連結具３，４と雌型連結具６，７の平面視における重合幅を該雌型連結具６，７側の陥没部分で確保することができることから、相互に連結される一方の単位浮体２Ａ側の各雄型連結具３、４と、他方の単位浮体２Ｂ側の各雌型連結具６、７をロッキングバー８によって同時に連結した状態においては、これら各単位浮体２Ａ、２Ｂの側面間の隙間を可及的に小さくすることができ、その結果、該隙間への作業用機器等の落下が未然に防止されることから、作業上の安全性が向上する、
（ａ−２）上記第２連結部Ｑの各雌型連結具６，７が、上記単位浮体２の側面から内部側へ陥没した構成であることから、該第２連結部Ｑが形成された側面側においては、該側面の位置を、該単位浮体２の輸送上の法規制寸法の限界位置近くまで拡大することで、浮力性能を法規制寸法の範囲内で可及的に高めることができ、それだけ単位浮体２の性能向上が図られる、
等の効果が得られる。 (A) According to the floating structure according to the first invention of the present application, a pair of upper and lower upper male connections in which the first connecting portion P provided on the side surface of the unit floating body 2 extends outward from the side surface. It is composed of a tool 3 and a lower male connector 4, and the second connector Q is composed of a pair of upper and lower upper female connectors 6 and 7 whose inner side is depressed from the side surface. Because
(A-1) Since the overlapping width in the plan view of the male couplers 3 and 4 and the female couplers 6 and 7 can be secured at the recessed portions on the female couplers 6 and 7 side, In a state in which the male connectors 3 and 4 on the one unit float 2A side and the female connectors 6 and 7 on the other unit float 2B side are simultaneously connected by the locking bar 8, these units are connected. The gap between the side surfaces of the floating bodies 2A and 2B can be made as small as possible. As a result, the work equipment or the like can be prevented from falling into the gap, thereby improving operational safety. ,
(A-2) Since each of the female couplers 6 and 7 of the second coupling part Q is recessed from the side surface of the unit floating body 2 to the inside, the second coupling part Q is formed. On the side surface side, the buoyancy performance can be enhanced as much as possible within the legally regulated dimension by expanding the position of the lateral surface to near the limit position of the legally regulated dimension for transportation of the unit floating body 2. Therefore, the performance improvement of the unit floating body 2 is achieved.
Etc. are obtained.

（ａ−３）上記ロッキングバー８を一体構成とし、該ロッキングバー８の上端側に位置して上記一方の単位浮体２Ａ側の上側雄型連結具３と上記他方の単位浮体２Ｂ側の上側雌型連結具６との間に嵌挿されてこれら両者を連結する上側ロック部１５と、該ロッキングバー８の下端側に位置して上記一方の単位浮体２Ａ側の下側雄型連結具４と上記他方の単位浮体２Ｂ側の下側雌型連結具７との間に嵌挿されてこれら両者を連結する下側ロック部１６を備えるとともに、上記ロッキングバー８と上記上側雄型連結具３又は上記上側雌型連結具６の間に、上記ロッキングバー８が連結状態から上方へ引き上げられて上記上側ロック部１５による連結作用と上記下側ロック部１６による連結作用が共に解除された状態において上記ロッキングバー８を上側雄型連結具３又は上側雌型連結具６から側方へ係合離脱させる係合離脱手段Ｒを備えているので、
（ａ−３−１）例えば、一方の単位浮体２Ａと他方の単位浮体２Ｂが分離状態にあり、且つ該第１連結部Ｐ側又は第２連結部Ｑ側の何れかに上記ロッキングバー８が挿通保持された状態から、一方の単位浮体２Ａと他方の単位浮体２Ｂを引き寄せてこれらを非連結状態から連結させる場合には、一旦、上記ロッキングバー８を引き上げて上記上側ロック部１５及び下側ロック部１６による連結作用を解除するような状態（即ち、上記上側ロック部１５が上記第１連結部Ｐ側の上側雄型連結具３及び上記第２連結部Ｑ側の上側雌型連結具６より上方に位置し、また上記下側ロック部１６が上記第１連結部Ｐ側の下側雄型連結具４及び上記第２連結部Ｑ側の下側雌型連結具７より上方に位置した状態）とすれば、該ロッキングバー８をこれ以上に上方へ引き抜かなくても、上記係合離脱手段Ｒの係合離脱作用により、該ロッキングバー８をこれが嵌挿されていない側の上側雄型連結具３又は上側雌型連結具６に対してその側方から嵌入させ得る状態となる（換言すれば、上記ロッキングバー８が、上記第１連結部Ｐの上側雄型連結具３と上記第２連結部Ｑの上側雌型連結具６を横方向へ相対移動させてこれらを上下方向に重合させる際に支障とならない）。 (A-3) The above - mentioned locking bar 8 is integrated, and the upper male connector 3 on the one unit floating body 2A side and the upper female on the other unit floating body 2B side are located on the upper end side of the locking bar 8. An upper locking portion 15 which is inserted between the mold coupling 6 and couples them, and a lower male coupling 4 located on the lower end side of the locking bar 8 on the one unit floating body 2A side. The lower locking part 16 is inserted between the lower female connector 7 on the side of the other unit floating body 2B and connects the two, and the locking bar 8 and the upper male connector 3 or In the state where the locking bar 8 is pulled upward from the connected state between the upper female connector 6 and the connecting action by the upper locking part 15 and the connecting action by the lower locking part 16 are both released. Locking bar 8 Since the upper male connector 3 or the upper female connector 6 and a disengaged means R for disengaging laterally,
(A-3-1) For example, one unit floating body 2A and the other unit floating body 2B are in a separated state, and the locking bar 8 is provided on either the first connection part P side or the second connection part Q side. When the one unit floating body 2A and the other unit floating body 2B are pulled together from the inserted and held state and are connected from the unconnected state, the locking bar 8 is once lifted to raise the upper lock portion 15 and the lower side. A state in which the connecting action by the lock part 16 is released (that is, the upper lock part 15 is connected to the upper male connector 3 on the first connecting part P side and the upper female connector 6 on the second connecting part Q side). The lower lock portion 16 is located above the lower male connector 4 on the first connecting portion P side and the lower female connector 7 on the second connecting portion Q side. State), the locking bar 8 should be Even when the locking bar 8 is not pulled out, the locking bar 8 is moved away from the upper male connector 3 or the upper female connector 6 on the side where the locking bar 8 is not inserted by the engagement / disengagement action of the engagement / disengagement means R. (In other words, the locking bar 8 causes the upper male connector 3 of the first connecting portion P and the upper female connector 6 of the second connecting portion Q to move in the lateral direction. It will not interfere with the vertical polymerization of these by moving them relative to each other).

従って、この状態から、上記一方の単位浮体２Ａと他方の単位浮体２Ｂを引き寄せることで、該ロッキングバー８を上記第１連結部Ｐ側の上側雄型連結具３又は第２連結部Ｑ側の上側雌型連結具６に対して側方から嵌入させることができる。そして、このロッキングバー８の嵌入後、該ロッキングバー８を下方へ降下させることで、該ロッキングバー８の上側ロック部１５及び下側ロック部１６による連結作用が達成され、該ロッキングバー８によって上記各単位浮体２Ａ、２Ｂが確実に連結保持される。 Accordingly, by pulling the one unit floating body 2A and the other unit floating body 2B from this state, the locking bar 8 is moved to the upper male connector 3 on the first connecting part P side or the second connecting part Q side. The upper female connector 6 can be fitted from the side. Then, after the locking bar 8 is fitted, the locking bar 8 is lowered to achieve a connecting action by the upper lock portion 15 and the lower lock portion 16 of the locking bar 8. Each unit floating body 2A, 2B is securely connected and held.

（ａ−３−２）一方、上記ロッキングバー８により各単位浮体２Ａ、２Ｂを連結した状態から、これらを分離させて解体する場合には、一旦、上記ロッキングバー８を引き上げて上記上側ロック部１５及び下側ピン６による連結作用を解除すると、これ以上に上記ロッキングバー８を上方へ引き抜かなくても、上記係合離脱手段Ｒの係合離脱作用により、上記ロッキングバー８を上記第１連結部Ｐ側の上側雄型連結具３又は第２連結部Ｑ側の上側雌型連結具６から側方へ離脱させることができる状態となる。従って、この状態から、上記一方の単位浮体２Ａと他方の単位浮体２Ｂを引き離すことで、上記ロッキングバー８が上記第１連結部Ｐの上側雄型連結具３側及び上記第２連結部Ｑの上側雌型連結具６側にそれぞれ存在しているのも拘らず、該各単位浮体２Ａ、２Ｂを容易に分離させてこれを解体することができる。 (A-3-2) On the other hand, when the unit floating bodies 2A and 2B are connected to each other by the locking bar 8 and separated from each other, the upper locking portion is temporarily lifted by lifting the locking bar 8 once. When the connecting action by the lower pin 6 and the lower pin 6 is released, the locking bar 8 is connected to the first connecting member by the engaging / disengaging action of the engaging / disengaging means R without further pulling the locking bar 8 upward. The upper male connector 3 on the part P side or the upper female connector 6 on the second connector Q side can be detached from the side. Therefore, from this state, when the one unit floating body 2A and the other unit floating body 2B are separated from each other, the locking bar 8 is connected to the upper male connector 3 side of the first connection part P and the second connection part Q. The unit floating bodies 2A and 2B can be easily separated and disassembled regardless of the existence on the upper female connector 6 side.

（ａ−３−３）以上のように、この発明の浮体構造体によれば、上記各単位浮体２Ａ、２Ｂの連結・分離作業に際して上記ロッキングバー８を大きく引き抜かなくても、該各単位浮体２Ａ、２Ｂを連結したり、分離させたりすることができるものであり、例えば、従来のように、連結・分離作業毎にロッキングバーを一旦取外す必要がある場合に比して、連結・分離作業における作業性が格段に向上し、迅速且つ確実な連結・分離作業が実現されることになる。

（ｂ）本願の第２の発明に係る浮体構造体によれば、上記（ａ）に記載の効果に加えて次のような特有の効果が得られる。即ち、この発明では、上記係合離脱手段Ｒを、上記ロッキングバー８の上記上側ロック部１５の直下側位置に設けられた扁平断面部１８と、上記上側雄型連結具３又は上側雌型連結具６に設けられて上記扁平断面部１８の通過を許容する切込溝３５で構成しているので、上記係合離脱手段Ｒを簡単な構造で、且つ安価に得ることができ、延いては浮体構造体全体の低コスト化にも寄与し得る。 (A-3-3) As described above, according to the floating body structure of the present invention, each unit floating body can be obtained without largely pulling out the locking bar 8 when connecting and separating the unit floating bodies 2A and 2B. 2A and 2B can be connected or separated. For example, compared to the case where it is necessary to remove the locking bar for each connection / separation operation as in the prior art, the connection / separation operation is possible. Thus, the workability in the process is greatly improved, and quick and reliable connection / separation work is realized.

(B) According to the floating structure according to the second invention of the present application, in addition to the effect described in the above (a) , the following specific effect is obtained. That is, according to the present invention, the engagement / disengagement means R is connected to the flat cross section 18 provided at a position directly below the upper lock portion 15 of the locking bar 8, the upper male connector 3 or the upper female connector. Since it is constituted by the cut groove 35 provided on the tool 6 and allowing the flat cross section 18 to pass therethrough, the engagement / disengagement means R can be obtained with a simple structure and at a low cost. It can also contribute to the cost reduction of the whole floating structure.

（ｃ）本願の第３の発明に係る浮体構造体によれば、上記（ａ）又は（ｂ）に記載の効果に加えて次のような特有の効果が得られる。即ち、この発明では、上記第１連結部Ｐ又は上記第２連結部Ｑに、上記ロッキングバー８の中段部分を支承する中間受部９を備えている。この場合、上記ロッキングバー８において、本来の連結機能の確保上、高い強度性能が要求されるのは、上記上側ロック部１５及び下側ロック部１６であって、それ以外の部分はこれら両ピン部１５、１６を連結してこれらの一体構造を保持し得れば十分であるため、該各ピン部１５，１６に対して低強度構造としてその軽量化及び低コスト化を図るようにしている。従って、この発明のように、上記中間受部９を設けることで、例え上記ロッキングバー８の上記上側ロック部１５と下側ロック部１６の中間部位が低強度構造とされていても、該中間受部９によってこれが支持されることでその座屈強度が確保され、該ロッキングバー８の使用上における信頼性が確保され、延いては上記ロッキングバー８による上記各単位浮体２Ａ、２Ｂの連結強度及びその信頼性が確保されることになる。 (C) According to the floating structure according to the third invention of the present application, in addition to the effect described in the above (a) or (b) , the following specific effect is obtained. That is, according to the present invention, the first connecting portion P or the second connecting portion Q is provided with an intermediate receiving portion 9 that supports the middle portion of the locking bar 8. In this case, in the locking bar 8, high strength performance is required for securing the original connecting function, the upper lock portion 15 and the lower lock portion 16, and the other portions are these two pins. Since it is sufficient that the parts 15 and 16 can be connected to hold the integrated structure, the pin parts 15 and 16 have a low-strength structure so as to reduce the weight and cost. . Therefore, by providing the intermediate receiving portion 9 as in the present invention, even if the intermediate portion between the upper lock portion 15 and the lower lock portion 16 of the locking bar 8 has a low strength structure, The buckling strength is ensured by being supported by the receiving portion 9, the reliability in use of the locking bar 8 is ensured, and the connection strength of the unit floating bodies 2A and 2B by the locking bar 8 is extended. And its reliability is ensured.

以下、本願発明を好適な実施形態に基づいて具体的に説明する。 Hereinafter, the present invention will be specifically described based on preferred embodiments.

図１には本願発明に係る浮体構造体１を、また図２には上記浮体構造体１を構成する単位浮体２を、それぞれ示している。 FIG. 1 shows a floating structure 1 according to the present invention, and FIG. 2 shows a unit floating body 2 constituting the floating structure 1.

上記浮体構造体１は、例えば、海面とか内水面に浮設されて水上作業における作業基地として使用されるものであって、所定の平面積が要求される。しかし、これを単一構成とすると、トラック輸送ができないことから、次述の単位浮体２を多数用意し、浮体構造体１としての必要平面積及び要求平面形状に応じて、上記単位浮体２を所定の配置パターンで順次横方向へ連設するようにしている。そして、この場合、最も問題となるのが単位浮体２相互間の連結構造であり、この実施形態では後述するような新規有用な連結構造を採用している。 The floating structure 1 is used, for example, as a work base for floating work by being floated on the sea surface or the inner water surface, and a predetermined plane area is required. However, if this is a single structure, truck transportation is not possible. Therefore, a large number of unit floating bodies 2 described below are prepared, and the unit floating bodies 2 are arranged according to the required plane area and the required plane shape as the floating structure 1. A predetermined arrangement pattern is sequentially arranged in the horizontal direction. In this case, the most problematic is the connection structure between the unit floating bodies 2. In this embodiment, a new useful connection structure as described later is adopted.

上記単位浮体２は、図２に示すように、鋼板製函体で構成され、平面視長矩形の天面２ａと、該天面２ａの長辺側に位置する第１長側面２ｂ及び第２長側面２ｃと、該天面２ａの短辺側に位置する第１短側面２ｄと第２短側面２ｅを備えている。ここで、上記単位浮体２の縦横比、即ち、各短側面２ｄ，２ｅの幅寸法と、各長側面２ｂ，２ｃの幅寸法の比率は、該単位浮体２を適宜組み合わせて上記浮体構造体１を構成する場合における組合せ形態を考慮して、「１：２」に設定している。係る設定によって、図１に示すように、上記単位浮体２を同方向へ連設する形態と、９０度回転させて連設する形態を任意に採ることができるものである。 As shown in FIG. 2, the unit floating body 2 is formed of a steel plate box, and has a top surface 2a having a rectangular shape in plan view, and a first long side surface 2b and a second side surface located on the long side of the top surface 2a. A long side surface 2c, a first short side surface 2d and a second short side surface 2e, which are located on the short side of the top surface 2a, are provided. Here, the aspect ratio of the unit floating body 2, that is, the ratio of the width dimension of each short side surface 2d, 2e and the width dimension of each long side surface 2b, 2c is appropriately combined with the unit floating body 2 to form the floating structure 1 Is set to “1: 2” in consideration of the combination form in the case of configuring.

Further, a slit-like engagement groove 27 is formed in the central portion of the inner periphery of the receiving groove portion 28 of the stop plate 26.

以上のように構成された上記第１連結部Ｐと第２連結部Ｑは、図２に示すように、上記単位浮体２の側面に取付けられる。 The 1st connection part P and the 2nd connection part Q which were comprised as mentioned above are attached to the side surface of the said unit floating body 2, as shown in FIG.

即ち、上記第１連結部Ｐは、上記単位浮体２の第１長側面２ｂの幅方向に離間した４位置と、上記第２短側面２ｅの幅方向に離間した２位置に、それぞれ設けられている。また、上記第２連結部Ｑは、上記単位浮体２の第２長側面２ｃの幅方向に離間した４位置と、上記第１短側面２ｄの幅方向に離間した２位置に、それぞれ設けられている。 That is, the first connecting portion P is provided at four positions spaced in the width direction of the first long side surface 2b of the unit floating body 2 and two positions spaced in the width direction of the second short side surface 2e. Yes. The second connecting portion Q is provided at four positions spaced in the width direction of the second long side surface 2c of the unit floating body 2 and two positions spaced in the width direction of the first short side surface 2d. Yes.

そして、上記各第１連結部Ｐは、間隔Ｓをもって配置された二つの第１連結部Ｐで一つの連結部ユニットＵ１を構成する。また、上記各第２連結部Ｑは、間隔Ｓをもって配置された二つの第２連結部Ｑで一つの連結部ユニットＵ２を構成する。このように各連結部ユニットＵ１，Ｕ２を構成することで、二つの単位浮体２、２を連結する場合、一方の単位浮体２側の連結部ユニットＵ１を、他方の単位浮体２側の連結部ユニットＵ２の何れをも選択して連結させることが可能となり、その結果、図１に示す浮体構造体１のように、上記各単位浮体２を任意に組み合わせて、所要形状及び所要寸法（所要平面積）をもつ浮体構造体１を得ることができるものである。 And each said 1st connection part P comprises one connection part unit U1 by the two 1st connection parts P arrange | positioned with the space | interval S. As shown in FIG. In addition, each of the second connecting portions Q constitutes one connecting portion unit U2 with two second connecting portions Q arranged with an interval S therebetween. By connecting each of the unit floating bodies 2 and 2 by configuring each of the connection unit U1 and U2 in this way, the connection unit U1 on one unit floating body 2 side is connected to the connection unit on the other unit floating body 2 side. Any of the units U2 can be selected and connected. As a result, the unit floating bodies 2 can be arbitrarily combined as in the floating body structure 1 shown in FIG. A floating structure 1 having an area) can be obtained.

一方、上記第１連結部Ｐ及び第２連結部Ｑに取付けられるロッキングバー８は、図１１に示すように、その上端側に位置し且つ円形の断面形状をもつピン状の上側ロック部１５と、その下端に位置し且つ円形の断面形状をもつピン状の下側ロック部１６を管体でなる連結杆１７によって同軸上に連結して構成されるが、この場合、上記上側ロック部１５の直下部分、即ち、上記連結杆１７の上端部分はこれを管体とするのに代えて、所定厚さの板材で構成し、これを扁平断面部１８としている。尚、この扁平断面部１８は、後述のように、上記第１連結部Ｐの上側雄型連結具３の切込溝３５内に進入可能とされるが、その一方で、上記上側雌型連結具６の嵌合穴３６をその軸方向へ通過し得る必要があることから、この実施形態では、上記扁平断面部１８の幅寸法を上記上側ロック部１５の径寸法より僅かに小さな寸法に設定している。 On the other hand, the locking bar 8 attached to the first connecting part P and the second connecting part Q, as shown in FIG. 11, is located on the upper end side thereof and has a pin-like upper lock part 15 having a circular cross section. The pin-like lower lock portion 16 located at the lower end and having a circular cross-sectional shape is coaxially connected by a connecting rod 17 made of a tubular body. In this case, the upper lock portion 15 is The portion directly below, that is, the upper end portion of the connecting rod 17 is formed of a plate material having a predetermined thickness instead of the tubular body, and this is a flat cross-sectional portion 18. As will be described later, the flat cross-sectional portion 18 can enter the cut groove 35 of the upper male connector 3 of the first connecting portion P. On the other hand, the upper female connector In this embodiment, the width dimension of the flat cross section 18 is set to be slightly smaller than the diameter dimension of the upper lock section 15 because the fitting hole 36 of the tool 6 needs to be able to pass in the axial direction. is doing.

また、上記連結杆１７の中段位置には、その軸方向に所定間隔をもって上側ストッパー２０と下側ストッパー２１が取付けられるとともに、これら各ストッパー２０、２１の間の外周面の一側には、該連結杆１７に軸方向に延びる回止リブ１９が設けられている。さらに、上記上側ロック部１５の頂部には、操作用の取手２２が設けられている。 Further, an upper stopper 20 and a lower stopper 21 are attached to the middle position of the connecting rod 17 with a predetermined interval in the axial direction thereof, and on one side of the outer peripheral surface between the stoppers 20 and 21, The connecting rod 17 is provided with a rotation stopping rib 19 extending in the axial direction. Further, a handle 22 for operation is provided on the top of the upper lock portion 15.

ここで、図３〜図１０を参照し、二つの単位浮体２間の連結・分離操作を、図１における浮体構造体１の隣接する一対の単位浮体（２Ａ及び２Ｂの符号を付した部分）を例にとって説明する。 Here, referring to FIG. 3 to FIG. 10, the connection / separation operation between the two unit floating bodies 2 is performed by a pair of adjacent unit floating bodies of the floating body structure 1 in FIG. Will be described as an example.

Ａ：連結状態の説明
図３には、一方の単位浮体２Ａと他方の単位浮体２Ｂの連結状態を示している。この連結状態では、これら二つの単位浮体２Ａ、２Ｂが接近し、該一方の単位浮体２Ａ側の上側雄型連結具３及び下側雄型連結具４が、他方の単位浮体２Ｂ側の上側雌型連結具６及び下側雌型連結具７に嵌合し、上下方向に重合した上記上側雄型連結具３の嵌合穴３４と上記上側雌型連結具６の嵌合穴３６には上記ロッキングバー８の上側ロック部１５が嵌挿され、また
上記下側雄型連結具４の嵌合穴４１と上記下側雌型連結具７の嵌合穴４２には上記ロッキングバー８の下側ロック部１６が嵌挿され、これら各ピン部１５，１６によって上記一方の単位浮体２Ａと他方の単位浮体２Ｂは強固に且つ確実に連結されている。 A: Description of Connected State FIG. 3 shows a connected state of one unit floating body 2A and the other unit floating body 2B. In this connected state, these two unit floats 2A and 2B approach each other, and the upper male connector 3 and the lower male connector 4 on the one unit float 2A side are connected to the upper female connector on the other unit float 2B side. The fitting hole 34 of the upper male connector 3 and the fitting hole 36 of the upper female connector 6 are fitted in the mold connector 6 and the lower female connector 7 and overlapped in the vertical direction. The upper locking portion 15 of the locking bar 8 is fitted and inserted into the fitting hole 41 of the lower male connector 4 and the fitting hole 42 of the lower female connector 7. The lock portion 16 is inserted and the one unit floating body 2 </ b> A and the other unit floating body 2 </ b> B are firmly and securely connected by the pin portions 15 and 16.

この場合、上記ロッキングバー８に設けられた扁平断面部１８は、上記上側雌型連結具６の下側に位置し、且つ図５に示すように、その断面長手方向が上記上側雄型連結具３側の切込溝３５の溝方向に直交する状態となっている。また、上記ロッキングバー８の連結杆１７の中段部に設けた上下一対のストッパー２０、２１のうち、上側ストッパー２０は上記中間受部９の止板２６の上面に係合しており、これによって上記ロッキングバー８の下動が規制されている（即ち、上記上側ストッパー２０は、上記ロッキングバー８の連結状態での位置保持機能を為す）。 In this case, the flat cross section 18 provided in the locking bar 8 is located below the upper female connector 6 and the longitudinal direction of the cross section is the upper male connector as shown in FIG. It is in a state orthogonal to the groove direction of the cut groove 35 on the 3 side. Of the pair of upper and lower stoppers 20, 21 provided at the middle stage of the connecting bar 17 of the locking bar 8, the upper stopper 20 is engaged with the upper surface of the stop plate 26 of the intermediate receiving part 9, thereby The downward movement of the locking bar 8 is restricted (that is, the upper stopper 20 performs a position holding function when the locking bar 8 is connected).

さらに、上記回止リブ１９は、上記中間受部９の受材２５の下側にあって、しかも図８に示すように、上記止板２６に設けた係合溝２７と直交する回動位置にある。従って、この回止リブ１９は、その上端が上記受材２５に係合することで上記ロッキングバー８の上方移動を規制し、上記ロッキングバー８による連結作用を確実ならしめている。 Further, the rotation rib 19 is located below the receiving member 25 of the intermediate receiving portion 9 and, as shown in FIG. 8, the rotation position orthogonal to the engagement groove 27 provided in the stop plate 26. It is in. Accordingly, the upper end of the locking rib 19 is engaged with the receiving member 25 to restrict the upward movement of the locking bar 8, thereby ensuring the connecting action by the locking bar 8.

ところで、このように一方の単位浮体２Ａと他方の単位浮体２Ｂを上記ロッキングバー８によって連結した状態においては、図３に示すように、これら両者が極めて接近した状態となっている。これは、上述のように、一方の単位浮体２Ａに設けられた上記第１連結部Ｐの上側雄型連結具３と下側雄型連結具４が該単位浮体２Ａの側面から外方へ延出した構成とされ、また他方の単位浮体２Ｂに設けられた上記第２連結部Ｑの上側雌型連結具６及び下側雌型連結具７が該単位浮体２Ｂの側面から内部側へ陥没した構成であって、これら各雄型連結具３，４と各雌型連結具６，７の平面視における重合幅を該雌型連結具６，７側の陥没部分で確保することができ、その分だけこれら各単位浮体２Ａ，２Ｂの側面を接近させて上記隙間を狭めることができたものである。このように、上記隙間を小さくできた結果、例えば、該隙間からの作業用機器等の落下が可及的に防止され、上記浮体構造体１としての作業上の高い安全性が確保される。 By the way, in the state where one unit floating body 2A and the other unit floating body 2B are connected by the locking bar 8 as described above, they are in an extremely close state as shown in FIG. As described above, the upper male connector 3 and the lower male connector 4 of the first connecting portion P provided on one unit floating body 2A extend outward from the side surface of the unit floating body 2A. The upper female connector 6 and the lower female connector 7 of the second connecting portion Q provided in the other unit floating body 2B are recessed from the side surface of the unit floating body 2B to the inner side. The overlapping width in the plan view of each of the male connectors 3 and 4 and each of the female connectors 6 and 7 can be secured at the recessed portion on the female connector 6 and 7 side, The gaps can be narrowed by bringing the side surfaces of these unit floating bodies 2A and 2B closer to each other. As described above, as a result of reducing the gap, for example, a work device or the like can be prevented from dropping from the gap as much as possible, and high safety in working as the floating structure 1 is ensured.

また、上述のように、上記第２連結部Ｑの各雌型連結具６，７が、上記単位浮体２Ｂの側面から内部側へ陥没した構成であることから、該第２連結部Ｑが形成された側面側においては、該側面の位置を、該単位浮体２Ｂの輸送上の法規制寸法の限界位置近くまで拡大することで、浮力性能を法規制寸法の範囲内で可及的に高めることができ、それだけ該単位浮体２Ｂの性能向上が図られることになる。 Further, as described above, each of the female couplers 6 and 7 of the second coupling part Q is recessed from the side surface of the unit floating body 2B to the inside, so that the second coupling part Q is formed. By increasing the position of the side surface to near the limit position of the legally regulated dimension for transportation of the unit floating body 2B, the buoyancy performance is increased as much as possible within the legally regulated dimension. As a result, the performance of the unit floating body 2B can be improved accordingly.

Ｂ：連結状態からの分離操作の説明
一方、上記各単位浮体２Ａ、２Ｂを、その連結状態（図３に示す状態）から分離させる場合には、先ず、上記ロッキングバー８を、上記取手２２を持って９０度回転させ、上記連結杆１７に設けた上記回止リブ１９を上記受材２５の係合溝２７に重合させる（図９参照）。
この状態で上記ロッキングバー８を、上記下側ストッパー２１が上記受材２５に当接するまで上方へ引き上げる（図４に示す状態）。この場合、上記回止リブ１９は、上記受材２５の係合溝２７に係入することで、上記ロッキングバー８の回動を規制し、上記扁平断面部１８を上記一方の単位浮体２Ａ側の上側雄型連結具３における上記切込溝３５と平行な姿勢で保持し、該扁平断面部１８が上記切込溝３５の側縁と干渉するのを防止する。尚、この下側ストッパー２１による上記扁平断面部１８の上記切込溝３５の側縁への干渉防止作用は、上記各単位浮体２Ａ、２Ｂを連結状態から分離させる場合のみならず、該各単位浮体２Ａ、２Ｂを分離状態から連結させる場合においても同様に得られるものである。 B: Description of Separation Operation from the Connected State On the other hand, when the unit floating bodies 2A, 2B are separated from the connected state (the state shown in FIG. 3), first, the locking bar 8 is moved to the handle 22 The rotating rib 19 provided on the connecting rod 17 is overlapped with the engaging groove 27 of the receiving member 25 (see FIG. 9).
In this state, the locking bar 8 is pulled upward until the lower stopper 21 contacts the receiving member 25 (the state shown in FIG. 4). In this case, the rotation rib 19 is engaged with the engagement groove 27 of the receiving member 25, thereby restricting the rotation of the locking bar 8, and the flat cross section 18 is moved to the one unit floating body 2A side. The upper male connector 3 is held in a posture parallel to the cut groove 35 to prevent the flat cross section 18 from interfering with the side edge of the cut groove 35. The interference of the lower stopper 21 to the side edge of the cut groove 35 of the flat cross section 18 is not limited to the case where the unit floating bodies 2A and 2B are separated from the connected state. The same can be obtained when the floating bodies 2A and 2B are connected from the separated state.

上記ロッキングバー８の引上げによって、上記上側ロック部１５及び下側ロック部１６は上記第１連結部Ｐ側の上側雄型連結具３及び下側雄型連結具４から上方へ離脱し、該各ピン部１５，１６による連結作用が解除される。これと同時に、図４及び図６に示すように、上記ロッキングバー８の扁平断面部１８の面方向が上記上側雄型連結具３の切込溝３５の溝方向に合致し、該扁平断面部１８が上記切込溝３５内を通って側方へ離脱し得る状態となっている（図７参照）。 When the locking bar 8 is pulled up, the upper lock portion 15 and the lower lock portion 16 are disengaged upward from the upper male connector 3 and the lower male connector 4 on the first connecting portion P side. The connecting action by the pin portions 15 and 16 is released. At the same time, as shown in FIGS. 4 and 6, the surface direction of the flat cross section 18 of the locking bar 8 matches the groove direction of the cut groove 35 of the upper male connector 3, and the flat cross section 18 is in a state where it can be detached laterally through the inside of the cut groove 35 (see FIG. 7).

従って、ここで、上記各単位浮体２Ａ，２Ｂを相互に離間させる方向に移動させることで、上記ロッキングバー８が上記上側雄型連結具３部分から下側雄型連結具４部分に掛けて存在しているにも拘らず、これに何等阻害されることなく、上記各単位浮体２Ａ，２Ｂが分離されるものである。尚、この実施形態では、上記ロッキングバー８の扁平断面部１８と上記上側雄型連結具３の切込溝３５によって特許請求の範囲中の「係合離脱手段Ｒ」が構成されている。 Therefore, here, by moving the unit floating bodies 2A and 2B in the direction of separating from each other, the locking bar 8 is hung from the upper male connector 3 portion to the lower male connector 4 portion. However, the unit floating bodies 2A and 2B are separated without being obstructed by this. In this embodiment, the flat section 18 of the locking bar 8 and the cut groove 35 of the upper male connector 3 constitute the “engagement / disengagement means R” in the claims.

上記各単位浮体２Ａ，２Ｂの分離後は、上記ロッキングバー８をそのまま上記下側ストッパー２１が上記受材２５に当接してそれ以上の降下が阻止されるまで降下させ、しかる後、該ロッキングバー８を９０度回転させて上記回止リブ１９を上記スリット２７に略直交させることで、上記ロッキングバー８はその上側ロック部１５を上記上側雌型連結具６側に、上記下側ロック部１６を上記下側雌型連結具７側にそれぞれ嵌挿させた状態で、保持され且つ抜け止めされる。 After the unit floating bodies 2A and 2B are separated, the locking bar 8 is lowered as it is until the lower stopper 21 abuts against the receiving member 25 to prevent further lowering, and then the locking bar 8 8 is rotated 90 degrees so that the locking rib 19 is substantially orthogonal to the slit 27, whereby the locking bar 8 has its upper locking portion 15 on the upper female connector 6 side and the lower locking portion 16. Are held and prevented from coming off in a state in which they are respectively inserted into the lower female connector 7 side.

このように、この実施形態の浮体構造体１においては、上記各単位浮体２Ａ、２Ｂの連結・分離作業に際して上記ロッキングバー８を大きく引き抜かなくても、該各単位浮体２Ａ、２Ｂを連結したり、分離させたりすることができるものであり、例えば、従来のように、連結・分離作業毎にロッキングバーを一旦取外す必要がある場合に比して、連結・分離作業における作業性が格段に向上し、迅速且つ確実な連結・分離作業が実現されることになる。 As described above, in the floating body structure 1 of this embodiment, the unit floating bodies 2A and 2B can be connected without largely pulling out the locking bar 8 when connecting and separating the unit floating bodies 2A and 2B. For example, as compared with the conventional case where the locking bar needs to be removed once for each connection / separation work, the workability in the connection / separation work is greatly improved. Thus, a quick and reliable connection / separation operation is realized.

また、この実施形態の浮体構造体１においては、上記第２連結部Ｑ側に、上記ロッキングバー８の中段部分を支承する中間受部９を備えているので、例え上記ロッキングバー８の上記上側ロック部１５と下側ロック部１６の中間に位置する連結杆１７部分が低強度構造とされていても、該中間受部９によってこれが支持されることでその座屈強度が確保され、該ロッキングバー８の使用上における信頼性が確保され、延いては上記ロッキングバー８による上記各単位浮体２Ａ、２Ｂの連結強度及びその信頼性が確保されることになる。 Moreover, in the floating body structure 1 of this embodiment, since the intermediate receiving portion 9 for supporting the middle portion of the locking bar 8 is provided on the second connecting portion Q side, for example, the upper side of the locking bar 8 Even if the connecting rod 17 portion positioned between the lock portion 15 and the lower lock portion 16 has a low-strength structure, the intermediate receiving portion 9 supports the buckling strength to secure the buckling strength. Reliability in use of the bar 8 is ensured, and as a result, the connection strength and reliability of the unit floating bodies 2A and 2B by the locking bar 8 are ensured.

尚、上記実施形態では、上記各単位浮体２Ａ，２Ｂの分離状態においては上記第２連結部Ｑ側に上記ロッキングバー８を保持するようにし、且つこれに対応して、上記上側雄型連結具３側に上記ロッキングバー８の扁平断面部１８の通過を許容する上記切込溝３５を形成していたが、本願発明は係る構成に限定されるものではなく、例えば、これとは逆に、
上記第１連結部Ｐ側に上記ロッキングバー８を保持するようにし、且つこれに対応して、上記上側雌型連結具６側に上記ロッキングバー８の扁平断面部１８の通過を許容する上記切込溝３５を形成することもできるものである。 In the above embodiment, in the separated state of the unit floating bodies 2A, 2B, the locking bar 8 is held on the second connecting portion Q side, and correspondingly, the upper male connecting tool The cut groove 35 that allows the flat cross-sectional portion 18 of the locking bar 8 to pass through is formed on the 3 side, but the present invention is not limited to such a configuration, for example, on the contrary,
The locking bar 8 is held on the first connecting part P side, and correspondingly, the cutting section that allows the flat cross section 18 of the locking bar 8 to pass on the upper female connector 6 side. The insertion groove 35 can also be formed.

Ｃ：その他
上記実施形態においては、上記ロッキングバー８の上側ロック部１５と下側ロック部１６を共に円形断面形状をもつピン状としているが、本願発明では係る構成に限定されるものではなく、他の実施形態においては、例えば、上記各ロック部１５、１６を方形の断面形状をもつ構成とすることもできる。尚、係る構成とした場合には、上記各ロック部１５、１６が方形の断面形状をもち、それ自体が回り止め機能を有することから、上記実施形態における「回止リブ１９」の付設は不要である。また、上記ロッキングバー８の上下方向における位置規制手段としては、上記実施形態のような連結杆１７の全周に跨るストッパー２０，２１を備える必要はなく、例えば、閂等の簡単な構成のものを適用することができる。 C: Others In the above embodiment, the upper lock portion 15 and the lower lock portion 16 of the locking bar 8 are both pin-shaped with a circular cross-sectional shape, but the present invention is not limited to such a configuration, In another embodiment, for example, each of the lock portions 15 and 16 may have a square cross-sectional shape. In the case of such a configuration, since each of the lock portions 15 and 16 has a square cross-sectional shape and itself has a non-rotating function, it is unnecessary to provide the “rotation rib 19” in the above embodiment. It is.
