Description

この発明は防舷材構造体に関し、特に船舶が接舷する際に岸壁等に設置して用いられる防舷材構造体に関するものである。   The present invention relates to a fender structure, and more particularly to a fender structure used by being installed on a wharf or the like when a ship is connected.

従来、防舷材の受衝部の表面(受衝面)を別の素材や別の部材で覆うことで、防舷材そのものを保護したり、接舷する船舶の汚れを防止したりする技術が種々提案されている。   Conventionally, the technology to protect the fender itself or to prevent the contamination of the ship to be connected, by covering the surface (the impact receiving surface) of the fender facing part with another material or another member Various proposals have been made.

例えば、特許文献1では、漁港を明るいイメージに変え、且つ、薄暮から夜間の船舶の接舷や作業時の安全向上のために、ソリッド型ゴム製防舷材に着色可能な素材からなる受衝板を本体の受衝面の上部から被せて一体として構成された岸壁用カラー防舷材が開示されている。   For example, in Patent Document 1, a fishing port is changed to a bright image, and for the purpose of improving the safety at the time of connection of a ship from night to night with a ship, the impact made of a material that can be colored with solid rubber fenders There is disclosed a collar fender for a quaywall integrally formed by covering a plate from the top of the impact surface of the main body.

又、特許文献2では、ゴム防舷材の外面にそれぞれが異なる色を有する複数層からなる受衝部材を固定したことを特徴とする防舷材が開示されている。この受衝部材が摩耗によって露出している部分の色が変化することで、受衝部材の寿命が容易に分かるようになっている。   Further, Patent Document 2 discloses a fender having a plurality of layers of impact receiving members fixed to an outer surface of a rubber fender, each having a different color. The life of the impact receiving member can be easily understood by changing the color of the exposed portion of the impact receiving member due to wear.

更に、特許文献3では、ゴム防舷材の船舶と接触する頭部表面にゴムよりも摩擦係数の小さい合成樹脂層を設けた防舷材が開示されている。この防舷材は、ゴムからなる部分と船舶との接触を避けて防舷材の摩耗による劣化を防ぐと共に、頭部部分が座屈しにくいようになっている。   Further, Patent Document 3 discloses a fender having a synthetic resin layer having a friction coefficient smaller than that of rubber on a head surface of the rubber fender to be in contact with a ship. This fender prevents contact between the rubber portion and the ship to prevent deterioration due to wear of the fender and makes the head portion less likely to buckle.

更に、特許文献4では、防舷材の劣化を防ぐために、中空の緩衝部を有するゴム等の弾性体にて形成された防舷材の表面を被覆するゴム製又は合成樹脂製のカバーと、緩衝部の上下開口部に配設され板面に挿通孔を有しカバーをその上下部で脱着自在に固定するための固定部を有する板状の固定板と、緩衝部に挿入され挿通孔に挿通され固定板を固定する固定軸とを備えた構成を有する防舷材カバーが開示されている。   Furthermore, in Patent Document 4, a rubber or synthetic resin cover that covers the surface of a fender formed of an elastic body such as rubber having a hollow buffer portion to prevent deterioration of the fender. A plate-like fixing plate having insertion holes in the plate surface and having fixing portions for detachably fixing the cover on the upper and lower portions thereof, and insertion holes inserted in the buffer portion and inserted in the insertion holes There is disclosed a fender cover having a configuration including a fixed shaft which is inserted and fixed a fixed plate.

上記の特許文献1のような従来の岸壁用カラー防舷材は、防舷材本体と受衝板とを嵌合させるために、防舷材本体を所定形状に加工する必要がある。そのため、加工の手間が生じると共に既存の防舷材には容易に適用できないものであった。   In the conventional color fender for quaywall as in Patent Document 1 described above, it is necessary to process the fender main body into a predetermined shape in order to fit the fender main body and the impact receiving plate. As a result, it takes time and effort to process and can not be easily applied to existing fenders.

又、上記の特許文献2のような従来の防舷材では、ゴム防舷材と受衝部材とを一体化するのに受衝部材側からボルト等の固定部材で固定するものである。そのため、受衝部材の脱着に手間がかかるものであった。又、雌ねじを設けた鋼板又は合成樹脂板をゴム防舷材の内部に埋め込む必要があり、既存の防舷材に適用できないものであった。   Further, in the conventional fender as in Patent Document 2 described above, the rubber fender and the impact receiving member are integrated with a fixing member such as a bolt from the impact receiving member side. Therefore, it took time to desorb the impact receiving member. In addition, it is necessary to embed a steel plate or a synthetic resin plate provided with a female screw in the inside of the rubber fender, which is not applicable to existing fenders.

更に、上記の特許文献3のような従来の防舷材では、合成樹脂層はゴム防舷材部分と加硫工程を経て一体形成されているものであるため分離ができず、合成樹脂層が破損した場合は防舷材そのものを取り替える必要があった。   Furthermore, in the conventional fenders such as Patent Document 3 described above, the synthetic resin layer can not be separated because it is integrally formed with the rubber fender portion through the vulcanization step, and the synthetic resin layer can not be separated. In the case of breakage, it was necessary to replace the fender itself.

更に、上記の特許文献4のような従来の防舷材カバーでは、防舷材カバーが複数の部材から構成されているため、その脱着に手間がかかるものであった。又、防舷材カバーを構成するカバー及び固定板を防舷材の形態に合わせて製作しなくてはならないため、防舷材カバーの汎用性が低かった。   Furthermore, in the conventional fender cover as in Patent Document 4 described above, since the fender cover is composed of a plurality of members, it takes time to remove and install the same. Moreover, since the cover and fixing plate which comprise a fender cover must be manufactured according to the form of a fender, the versatility of a fender cover was low.

これらの図を参照して、防舷材構造体1は、ゴム等の弾性材料からなり、図示しない船舶の接舷時の衝撃を和らげるための受衝部13及び防舷材構造体1を図示しない岸壁に取り付けるための岸壁取付部19a、19bを含む防舷材本体11と、防舷材構造体1と同一のゴム等の弾性材料からなる受衝部カバー体41とから構成されている。この受衝部カバー体41は、防舷材本体11の受衝部13の表面14(受衝面)の全体を覆うように脱着自在に取り付けられている。この防舷材本体11及び受衝部カバー体41の詳細な構造等については後述する。防舷材構造体1は、岸壁取付部19a、19bを岸壁に配置し、ボルト取付穴20a〜20d等を用いてアンカーボルト(図示せず)によって固定される。即ち、岸壁にアンカーボルトを埋設し、防舷材本体11のボルト取付穴20a〜20dにこのアンカーボルトを挿通させ、これにナット(図示せず)を螺合させて締め付けることにより、防舷材構造体1を岸壁に固定することができる。   Referring to these drawings, fender structure 1 is made of an elastic material such as rubber, and illustrates not-shown impact portion 13 and fender structure 1 for cushioning an impact at the time of landing of a ship (not shown). It comprises a fender main body 11 including quay attaching parts 19a and 19b for attaching to a quay where there is no space, and a shock receiving part cover body 41 made of an elastic material such as rubber similar to that of the fender structure 1. The impact cover member 41 is detachably attached so as to cover the entire surface 14 (incident surface) of the impact receiving portion 13 of the fender main body 11. Detailed structures and the like of the fender main body 11 and the impact receiving portion cover body 41 will be described later. The fender structure 1 has the quay mounting parts 19a and 19b disposed on the quay, and is fixed by anchor bolts (not shown) using bolt mounting holes 20a to 20d and the like. That is, the anchor bolt is embedded in the quay, the anchor bolt is inserted into the bolt mounting holes 20a to 20d of the fender main body 11, and a nut (not shown) is screwed into and tightened with this. The structure 1 can be fixed to the quay.

防舷材構造体1に図示しない船舶が接舷する際には、防舷材本体11の受衝部13でその衝撃を吸収するが、受衝部13の表面14は受衝部カバー体41に覆われているため、船舶は防舷材本体11には直接接触しにくくなる。これにより、防舷材本体11よりも船舶と直接接触する頻度の高い受衝部カバー体41が先に損傷することが多い。その際には、上述のように、受衝体カバー体41は防舷材本体11に脱着自在に取り付けられているため、損傷した受衝部カバー体41のみを交換することができる。よって、防舷材本体11を長期間使用できると共に、防舷材構造体1全体の交換頻度が低減する。   When a ship (not shown) is connected to the fender structure 1, the impact receiving portion 13 of the fender main body 11 absorbs the impact, but the surface 14 of the impact receiving portion 13 has the impact receiving portion cover body 41. Because it is covered by the above, it is difficult for the ship to directly contact the fender main body 11. As a result, in many cases, the impact receiving part cover body 41, which is more frequently in direct contact with the ship than the fender body 11, is damaged earlier. At that time, as described above, since the impact receiving body cover body 41 is detachably attached to the fender main body 11, only the damaged impact receiving portion cover body 41 can be replaced. Thus, the fender body 11 can be used for a long time, and the frequency of replacement of the entire fender structure 1 is reduced.

次に、防舷材本体11の具体的な構造について説明する。   Next, the specific structure of the fender main body 11 will be described.

図5は、図1で示した防舷材構造体の防舷材本体の概略正面図であり、図6は、図5で示した防舷材本体の概略右側面図であり、図7は、図5で示した防舷材本体の概略平面図であり、図8は、図5で示したVIII−VIIIラインから見た概略断面図である。   FIG. 5 is a schematic front view of the fender body of the fender structure shown in FIG. 1, FIG. 6 is a schematic right side view of the fender body shown in FIG. 5 is a schematic plan view of the fender body shown in FIG. 5, and FIG. 8 is a schematic cross-sectional view seen from the line VIII-VIII shown in FIG.

これらの図を参照して、防舷材本体11は、長手方向に延びる平面視略V字形状であって、長手方向の両端部27a、27bが開放された中空部23を有している。   Referring to these drawings, the fender main body 11 has a hollow portion 23 which is generally V-shaped in plan view extending in the longitudinal direction and in which both longitudinal end portions 27a and 27b are open.

又、防舷材本体11の受衝部13の短手方向の両端部28a、28bには、凹形状の窪みである4つの第1係合部55a〜55dが設けられている。この第1係合部55a〜55dの各々は、後述する受衝部カバー体に設けられている第2係合部と互いに係合するように配置されている。   Further, at the both end portions 28a and 28b of the impact receiving portion 13 of the fender main body 11 in the lateral direction, four first engagement portions 55a to 55d which are concaves having a concave shape are provided. Each of the first engagement portions 55a to 55d is arranged to engage with a second engagement portion provided on the impact cover body described later.

上記の各々のように構成した理由については後述する。   The reasons for the above-described configurations will be described later.

続いて、受衝部カバー体41の具体的な構造について説明する。   Subsequently, a specific structure of the impact cover body 41 will be described.

図9は、図1で示した防舷材構造体の受衝部カバー体の概略正面図であり、図10は、図9で示した受衝部カバー体の概略背面図であり、図11は、図9で示した受衝部カバー体の概略右側面図であり、図12は、図9で示した受衝部カバー体の保護部材を外した状態の概略平面図であり、図13は、図9で示した受衝部カバー体の保護部材を外した状態の概略底面図であり、図14は、図10で示したXIV−XIVラインから見た概略断面図である。   FIG. 9 is a schematic front view of the impact cover body of the fender structure shown in FIG. 1, and FIG. 10 is a schematic rear view of the impact cover body shown in FIG. 12 is a schematic right side view of the impact part cover body shown in FIG. 9, and FIG. 12 is a schematic plan view of a state in which the protection member of the impact part cover body shown in FIG. FIG. 14 is a schematic bottom view of a state in which the protective member of the impact part cover body shown in FIG. 9 is removed, and FIG. 14 is a schematic cross-sectional view seen from the XIV-XIV line shown in FIG.

これらの図を参照して、受衝部カバー体41は、正面視略矩形形状且つ平面視略台形形状である。又、受衝部カバー体41の防舷材本体11の受衝部13と接する面である背面46には、図5で示す防舷材本体11の受衝部13の周縁に合わせてくり抜かれている。即ち、背面46に凹部50が形成され、この凹部50内に、受衝部13の表面14側の一部を収納可能となっている。   Referring to these drawings, impact receiving part cover body 41 has a substantially rectangular shape in a front view and a substantially trapezoidal shape in a plan view. The back surface 46 of the fender cover 11 in contact with the impact part 13 of the fender cover 11 is hollowed out in conformity with the periphery of the impact part 13 of the fender main body 11 shown in FIG. ing. That is, the recess 50 is formed in the back surface 46, and a part of the surface 14 side of the impact receiving portion 13 can be stored in the recess 50.

又、この受衝部カバー体41の背面46(凹部50の内表面)には、ゴム等からなる半球形状の突起体51が一定の間隔で複数設けられている。   Further, on the back surface 46 (the inner surface of the recess 50) of the impact receiving portion cover body 41, a plurality of hemispherical protrusions 51 made of rubber or the like are provided at regular intervals.

更に、受衝部カバー体41の背面46側の短手方向の両端部48a、48b(凹部50の長手方向に沿った内側面)には、図5に示す第1係合部55a〜55dの形状に対応する、凸形状の4つの第2係合部56a〜56dが設けられている。この第2係合部56a〜56dの各々は、上述したように、図5に示す防舷材本体11に設けられている第1係合部55a〜55dと互いに係合するものである。   Further, both end portions 48a and 48b in the short direction of the back surface 46 side of the impact receiving portion cover body 41 (inner side surface along the longitudinal direction of the recess 50) of the first engaging portions 55a to 55d shown in FIG. Four convex second engaging portions 56a to 56d corresponding to the shape are provided. As described above, the second engaging portions 56a to 56d engage with the first engaging portions 55a to 55d provided on the fender main body 11 shown in FIG.

更に、防舷材構造体1が長手方向を水平方向にして設置される場合、受衝部カバー体41は、図9及び図11で示すように長手方向(水平方向)の両端部47a、47bに略かまぼこ形状の保護部材61a、61bを更に備えている。この保護部材61a、61bは、対応する防舷材本体11の側面部17a、17bのうち、受衝部13側の一部を覆うものである。   Furthermore, when the fender structure 1 is installed with the longitudinal direction in the horizontal direction, the impacting part cover body 41 has both end portions 47a and 47b in the longitudinal direction (horizontal direction) as shown in FIGS. In addition, it has further protective members 61a and 61b of substantially semicylindrical shape. The protective members 61 a and 61 b cover a part of the side surface parts 17 a and 17 b of the corresponding fender main body 11 on the side of the impact receiving part 13.

上記の各々のように構成した理由については後述する。   The reasons for the above-described configurations will be described later.

更に、この受衝部カバー体41の背面46側の長手方向の両端部49a、49bには、それぞれ受衝部カバー体41を防舷材本体11に固定するための固定部材65が取り付けられている。この固定部材65は、ゴム等からなる平らな紐状部材である帯66と、帯66を固定する紐状部材固定具であるバックル67とからなる。受衝部カバー体41の底面側には帯66の基端部が取り付けられており、上面側にはバックル67が取り付けられている。   Further, fixing members 65 for fixing the impact cover body 41 to the fender main body 11 are attached to both end portions 49a and 49b in the longitudinal direction of the rear face 46 side of the impact cover body 41. There is. The fixing member 65 includes a band 66 which is a flat cord-like member made of rubber or the like, and a buckle 67 which is a cord-like member fixing member for fixing the band 66. The base end of the band 66 is attached to the bottom surface side of the impact receiving part cover body 41, and the buckle 67 is attached to the top surface side.

固定部材65を用いて受衝部カバー体41を防舷材本体11に固定するにあたっては、図3及び図4を再度参照して、帯66の先端部を防舷材本体11の中空部23内に、底面側の開口から上面側の開口に向かって挿通させ、これをバックル67に通して固定する。この際、帯66が防舷材本体11の受衝部13側の裏面15に沿うように引き締める。すると、帯66は、中空部23を介して受衝部13側の裏面に沿って配置される。   In fixing the impact receiving part cover body 41 to the fender main body 11 by using the fixing member 65, referring to FIGS. 3 and 4 again, the tip end portion of the band 66 is the hollow portion 23 of the fender main body 11. Inside, it is inserted from the opening on the bottom side toward the opening on the top side, and fixed by passing it through the buckle 67. At this time, the band 66 is tightened along the back surface 15 of the fender body 11 on the side of the impact receiving portion 13. Then, the band 66 is disposed along the back surface on the side of the impact receiving portion 13 via the hollow portion 23.

こうすることで、防舷材本体11と受衝部カバー体41とが不用意に分離しにくくなるため、防舷材構造体1の使用時の信頼性が向上する。又、受衝部カバー体41を取り外す時には、バックル67から帯66を取り外せばよいので、受衝部カバー体41の脱着が容易となり、防舷材構造体1の使い勝手がよくなる。   By doing this, since the fender body 11 and the impact receiving part cover body 41 are difficult to be separated carelessly, the reliability when using the fender structure 1 is improved. Further, when removing the impact receiving portion cover body 41, the band 66 may be removed from the buckle 67, so that the impact receiving portion cover body 41 can be easily detached and the fender structure 1 can be used easily.

引き続き、防舷材構造体の防舷材本体や受衝部カバー体に設けられた突起体等の働きについて説明する。   Subsequently, the functions of the fender main body of the fender structure and the projections provided on the impact receiving portion cover body will be described.

図15は、図1で示した防舷材構造体の突起体の働きを示す概略模式図であって、(1)は、船舶が防舷材構造体に接舷する前の状態を示す図であり、(2)は、船舶が防舷材構造体に接舷すると共に水平方向に更に移動する状態を示す図である。   FIG. 15 is a schematic view showing the function of the protrusion of the fender structure shown in FIG. 1, wherein (1) shows a state before the ship comes in contact with the fender structure. (2) is a figure which shows the state which a ship further moves to a horizontal direction while making contact with a fender structure.

図15の(1)を参照して、防舷材構造体1は、長手方向が水面に対して垂直になるように岸壁80に設置されているものである。船舶81が接舷していない場合には、防舷材本体11の受衝部13の表面14と受衝部カバー体41の背面46に形成された突起体51の先端が接している状態である。   Referring to (1) of FIG. 15, the fender structure 1 is installed on the quay 80 so that the longitudinal direction is perpendicular to the water surface. When the ship 81 is not in contact with the front surface 14 of the impact receiving portion 13 of the fender main body 11 and the tip end of the projection 51 formed on the back surface 46 of the impact receiving portion cover body 41 is there.

図15の(2)を参照して、防舷材構造体1に船舶81が接舷すると、受衝部カバー体41は防舷材本体11の受衝部13の表面14に押し付けられる。その際、防舷材本体11は、ゴム等の弾性材料から構成されているため、受衝部13の表面14が受衝部カバー体41の突起体51の表面形状に合わせて変形し、受衝部カバー体41と防舷材本体11とが接している部分の表面積が大きくなる。そのため、防舷材本体11と受衝部カバー体41との間に発生する摩擦力が大きくなる。すると、船舶81の接舷時にはその移動に合わせて矢印で示す水平方向の力Fがかかる場合があるが、その際に防舷材本体11と受衝部カバー体41とがずれにくくなる。 Referring to (2) of FIG. 15, when the ship 81 is brought into contact with the fender structure 1, the impact cover portion 41 is pressed against the surface 14 of the impact portion 13 of the fender body 11. At that time, since the fender main body 11 is made of an elastic material such as rubber, the surface 14 of the impact receiving portion 13 is deformed in accordance with the surface shape of the protrusion 51 of the impact receiving portion cover body 41. The surface area of the portion where the impact portion cover body 41 and the fender main body 11 are in contact is increased. Therefore, the frictional force generated between the fender main body 11 and the impact receiving portion cover body 41 is increased. Then, at the time Seffunabata of the ship 81 there is a case where horizontal force F 1 indicated by the arrow in accordance with the movement thereof is applied, this time the fender main body 11 and the impact receiving portion cover body 41 is hardly displaced in the.

図16は、図1で示した防舷材構造体の係合部の働きを模式的に示す概略図であって、(1)は、係合部にせん断力がどのように働くかを示すものであり、(2)は、平行な向きの力が受衝部カバー体に生じる第2せん断強度を超えるせん断力を発生させる場合を示すものである。尚、図16では、理解を容易にするため、第1係合部55及び第2係合部56の形状を単純化すると共に、形成位置を中央部に変更している。   FIG. 16 is a schematic view schematically showing the function of the engaging portion of the fender structure shown in FIG. 1, wherein (1) shows how shear force acts on the engaging portion. (2) shows the case where a force in a parallel direction generates a shear force exceeding the second shear strength generated in the impact portion cover body. In FIG. 16, in order to facilitate understanding, the shapes of the first engagement portion 55 and the second engagement portion 56 are simplified, and the formation position is changed to the central portion.

図16の(1)を参照して、防舷材構造体1は、長手方向が水面に対して垂直になるように岸壁80に設置されているものである。防舷材本体11は、受衝部13の表面14に凹形状の窪みである第1係合部55を備えている。又、受衝部カバー体41は、防舷材本体11の受衝部13と接する平面である背面46に第1係合部55の窪みに対応するような凸形状の第2係合部56を備えている。この第1係合部55と第2係合部56とは、互いに係合するように配置されている。   Referring to (1) of FIG. 16, the fender structure 1 is installed on the quay 80 so that the longitudinal direction is perpendicular to the water surface. The fender main body 11 is provided with a first engaging portion 55 which is a concave having a concave shape on the surface 14 of the impact receiving portion 13. Further, the impact receiving portion cover body 41 has a convex second engaging portion 56 corresponding to the recess of the first engaging portion 55 on the back surface 46 which is a flat surface contacting the impact receiving portion 13 of the fender main body 11. Is equipped. The first engagement portion 55 and the second engagement portion 56 are arranged to engage with each other.

防舷材本体11に外力が作用した場合において、この外力における受衝面14と平行な方向の成分、即ち矢印で示す力Fが受衝部カバー体41に加わると、防舷材本体11の二点鎖線で示されたエリアAと受衝部カバー体41の一点鎖線で示されているエリアAとには各々せん断力がかかることになる。このせん断力の大きさは、力Fの大きさによって変化すると言える。エリアA及びエリアAにかかるせん断力に応じて、防舷材本体11や受衝部カバー体41に生じるせん断応力が、これらのせん断強度を超えた場合、防舷材本体11又は受衝部カバー体41はせん断破壊を起こすことになる。この実施の形態による防舷材本体11と受衝部カバー体41とは同一の素材であるため、防舷材本体11のせん断強度S及び受衝部カバー体41のせん断強度Sは同一であると言える。 In the case where external force to the fender main body 11 is applied, the impact receiving surface 14 parallel to the direction of the components in the external force, i.e. the force F 2 indicated by an arrow is applied to the impact receiving portion cover member 41, the fender main body 11 each will be shearing force is applied to the area a 2, shown in the indicated area a 1 and the impact receiving portion dashed line of the cover body 41 by a two-dot chain line in. The magnitude of this shearing force can be said to vary with the magnitude of the force F 2. When the shear stress generated in the fender main body 11 or the impact receiving part cover body 41 exceeds the shear strength in accordance with the shear force applied to the area A 1 and the area A 2 , the fender main body 11 or the impact receiving The partial cover body 41 causes shear failure. Because the fender main body 11 and the impact receiving portion cover 41 according to this embodiment is the same material, the shear strength S 2 of the shear strength S 1 and the impact receiving portion cover body 41 of the fender main body 11 are the same It can be said that

ここで、防舷材構造体1は、力Fがかかった時における、第1係合部55を介して防舷材本体11にせん断破壊を生じさせる第1の力Pは、第2係合部56を介して受衝部カバー体41にせん断破壊を生じさせる第2の力Pより大きく設定されるものである。この設定は、例えばエリアAの面積をエリアAの面積に比べて十分大きくすることによって可能である。 Here, when the fender structure 1 is subjected to the force F 2 , the first force P 1 causing the fender body 11 to cause shear failure via the first engagement portion 55 is the second force P 2. The second force P 2 is set to be larger than the second force P 2 that causes the impact cover body 41 to cause a shear failure via the engagement portion 56. This setting is possible by sufficiently larger than for example the area of the area A 1 to the area of the area A 2.

力Fが受衝部カバー体41にせん断破壊を生じさせない程度の第2の力P未満の大きさで受衝部カバー体41にかかった場合には、第2係合部56と第1係合部55とは係合したままの状態となり、力Fに対する受衝部カバー体41の移動が抑えられるため、防舷材本体11と受衝部カバー体41との嵌合状態が安定する。 When the force F 2 is applied to the impact cover body 41 with a magnitude smaller than the second force P 2 to the extent that the impact cover body 41 does not cause shear failure, the second engagement portion 56 and the second engagement portion 56 The engagement state between the fender cover body 41 and the impact cover body 41 is obtained because the movement of the impact cover body 41 with respect to the force F 2 is suppressed. Stabilize.

次に図16の(2)を参照して、力FがFまで大きくなると、それに合わせて、エリアA及びエリアAに作用するせん断力も大きくなる。すると、防舷材本体11や受衝部カバー体41にせん断強度S及びSを超えるせん断応力が発生することがある。その際には、上述したように第1の力P>第2の力Pの関係であるため、力Fが第2の力Pを超えると、防舷材本体11より先に受衝部カバー体41がエリアAでせん断破壊を生じさせることにより、防舷材本体11は破損しにくくなる。よって、破壊された受衝部カバー体41のみを交換すればよくなる。 Referring now to (2) in FIG. 16, when a force F 2 is increased up to F 3, accordingly, the greater the shearing force acting on the area A 1 and the area A 2. Then, it may shear stress exceeding the shear strength S 1 and S 2 to the fender main body 11 and the impact receiving portion cover body 41 is generated. At that time, since the relationship of the first force P 1 > the second force P 2 as described above, if the force F 3 exceeds the second force P 2 , the fender body 11 is preceded by by impact receiving portion cover body 41 causes a shear fracture in the area a 2, fender body 11 is hardly damaged. Therefore, it is sufficient to replace only the destroyed impact cover body 41.

反対に、第2の力Pが第1の力Pより大きく設定されていると仮定する。この場合、力FがFまで大きくなると、防舷材本体11のせん断強度Sを超えるせん断応力が発生することがある。その際には、第1の力P<第2の力Pの関係から、受衝部カバー体41より先に防舷材本体11がエリアAで破壊され、防舷材本体11が損傷することになる。 Conversely, assume that the second force P 2 is greater than the first force P 1. In this case, the force F 2 is increased up to F 3, which may shear stress exceeding the shear strength S 1 of the fender main body 11 is generated. At that time, the fender main body 11 is destroyed in the area A 1 earlier than the impact receiving part cover body 41 from the relationship of the first force P 1 <the second force P 2 , and the fender main body 11 is It will be damaged.

図17は、図1で示した防舷材構造体の保護部材の働きを示す概略模式図であって、(1)は、船舶が防舷材構造体に接舷する前の状態を示す図であり、(2)は、船舶が防舷材構造体の一方に偏って接舷した状態を示す図である。   FIG. 17 is a schematic view showing the function of the protective member of the fender structure shown in FIG. 1, wherein (1) shows a state before the ship comes in contact with the fender structure. (2) is a figure which shows the state which the ship was biased to one side of a fender structure, and was connected.

図17の(1)を参照して、防舷材構造体1は、長手方向が水面と平行になるように岸壁80に設置されているものである。このような状態の防舷材構造体1に船舶81が接舷する際、その接舷状態によっては防舷材構造体1の一部にのみ船舶81が接触することで、防舷材構造体1全体に均等に力がかからず、その一部のみに力がかかる場合がある。   Referring to (1) of FIG. 17, the fender structure 1 is installed on the quay 80 so that the longitudinal direction is parallel to the water surface. When the ship 81 is in contact with the fender structure 1 in such a state, depending on the contact state, the ship 81 contacts only a part of the fender structure 1 to make the fender structure (1) The force may not be evenly applied to the whole, but only a part of it may be applied.

具体的には、図17の(2)を参照して、受衝部カバー体41における水平方向の一方の端部47a側に力がかかった場合、防舷材構造体1は一方の端部47a側が他方の端部47b側に対して大きく変形する。もし仮に、保護部材61aがなければ、一点鎖線で示すように、船舶81は防舷材本体11の側面部17aに直接接触する虞がある。これに対し保護部材61aがあれば、船舶81は実線で示すように保護部材61aに先に接触することになる。これにより、防舷材本体11の側面部17aが保護部材61aによって保護されるため、船舶81の接舷によって防舷材本体11の側面部17aが破損する虞を低減できる。   Specifically, referring to (2) in FIG. 17, when a force is applied to one end 47 a side in the horizontal direction in impact receiving part cover body 41, fender structure 1 is one end The 47a side is largely deformed with respect to the other end 47b side. If the protective member 61a is not present, the ship 81 may be in direct contact with the side surface portion 17a of the fender main body 11, as indicated by the one-dot chain line. On the other hand, if there is the protective member 61a, the ship 81 comes in contact with the protective member 61a first as shown by the solid line. As a result, the side surface portion 17a of the fender main body 11 is protected by the protective member 61a, so that the possibility of the side surface portion 17a of the fender main body 11 being damaged by contact of the ship 81 can be reduced.

尚、上記の実施の形態では、受衝部カバー体は、防舷材本体の受衝部の表面の全体を覆うものであったが、受衝部の表面の少なくとも一部を覆うものであればよい。   In the above embodiment, although the impact receiving part cover body covers the entire surface of the impact receiving part of the fender main body, it may cover at least a part of the surface of the impact receiving part Just do it.

又、上記の実施の形態では、受衝部カバー体の裏面には複数の突起体が設けられる構成であったが、突起体はなくてもよい。   Further, in the above embodiment, the plurality of projections are provided on the back surface of the impact receiving part cover body, but the projections may be omitted.

又、上記の実施の形態では、受衝部カバー体の裏面に設けられた複数の突起体は半球形状のものであったが、別の形状のものであってもよい。   Moreover, in said embodiment, although the some protrusion provided in the back surface of the impact part cover body was a hemispherical shape, it may be another shape.

更に、上記の実施の形態では、防舷材本体の受衝部に第1係合部と、受衝部カバー体の防舷材本体の受衝部と接する平面に第2係合部が設けられる構成であったが、この第1係合部及び第2係合部は設けなくてもよい。   Furthermore, in the above embodiment, the second engagement portion is provided on the plane contacting the first engagement portion at the impact receiving portion of the fender main body and the impact receiving portion of the fender main body of the impact receiving portion cover body. However, the first engaging portion and the second engaging portion may not be provided.

However, the present invention is not limited to this. At least one first engagement portion and at least one second engagement portion may be provided at positions corresponding to each other. In addition, the first engagement portion may be formed in a convex shape, and the second engagement portion may be formed in a concave shape. Even in these cases, when a force in a direction parallel to the plane in contact with the impact receiving portion of the fender main body is applied to the impact receiving portion cover body, the fender main body via the first engaging portion If the first force causing the shear failure is set to be larger than the second force causing the impact failure cover body to cause the shear failure via the second engagement portion, the force in the parallel direction is When the increase is made, the impact part cover body is first destroyed as in the above embodiment. As a result, the risk of breakage of the fender main body is reduced, and it is sufficient to replace only the impact cover portion.

更に、上記の実施の形態では、保護部材は受衝部カバー体の長手方向の両端部に設けられる構成であったが、長手方向の端部の少なくとも一方に設けられる構成であればよい。又、保護部材は設けなくてもよい。   Furthermore, in the above embodiment, the protection members are provided at both end portions in the longitudinal direction of the impact receiving part cover body, but may be provided at at least one of the end portions in the longitudinal direction. Also, the protective member may not be provided.

更に、上記の実施の形態では、保護部材は防舷材本体の側面部であって受衝部側の一部を覆うものであったが、防舷材本体の側面部の全面を覆う構成としてもよい。   Furthermore, in the above embodiment, the protective member is a side surface portion of the fender main body and covers a part on the impact receiving portion side, but as a configuration which covers the entire side surface portion of the fender main body It is also good.

更に、上記の実施の形態では、固定部材の紐状部材(帯)と紐状部材固定具(バックル)とを備えるものであったが、固定部材はなくてもよい。   Furthermore, in the above embodiment, the cord-like member (band) of the fixing member and the cord-like member fastener (buckle) are provided, but the fastening member may be omitted.

更に、上記の実施の形態では、固定部材の紐状部材と紐状部材固定具とは帯とバックルとからなるものであったが、これに限らない。紐状部材が防舷材本体の中空部を介して受衝部側の裏面に配置され紐状部材固定具によって固定されるものであれば、例えばワイヤーとフック等といった他の部材を用いてもよい。又、紐状部材は、ゴムや樹脂によって被覆したり、ゴムや樹脂からなる筒状体によって覆ったりしてもよい。   Furthermore, in the above-mentioned embodiment, although the string-like member of a fixed member and a string-like member fastener consisted of a belt and a buckle, it is not restricted to this. As long as the string-like member is disposed on the rear surface of the impact receiving portion via the hollow portion of the fender main body and fixed by the string-like member fastener, other members such as a wire and a hook may be used. Good. Further, the string-like member may be covered with rubber or resin, or covered with a cylindrical body made of rubber or resin.

更に、上記の実施の形態では、固定部材の紐状部材と紐状部材固定具とが固定される位置は防舷材本体の中空部の一方の開口付近であったが、固定位置はこれに限らない。例えば、中空部の中央付近等、他の位置で固定する構成としてもよい。   Furthermore, in the above embodiment, the position where the string-like member of the fixing member and the string-like member fixture are fixed is near one opening of the hollow portion of the fender body, but the fixing position is Not exclusively. For example, it is good also as composition fixed at other positions, such as near the center of a hollow part.

更に、上記の実施の形態では、防舷材本体は中空部を有するものであったが、中空部はなくてもよい。   Furthermore, although the fender body has the hollow portion in the above embodiment, the hollow portion may be omitted.

更に、上記の実施の形態では、防舷材本体は平面視略V字形状のものであったが、例えば円錐台形状等といった他の形状の防舷材にも同様に適用できる。   Furthermore, in the above embodiment, the fender body is substantially V-shaped in a plan view, but the present invention is similarly applicable to fenders of other shapes such as a truncated cone shape.

更に、上記の実施の形態では、受衝部カバー体は正面視矩形形状且つ平面視略台形形状のものであったが、その他の形状であってもよい。   Furthermore, in the above embodiment, the impact cover body has a rectangular shape in a front view and a substantially trapezoidal shape in a plan view, but may have other shapes.

更に、防舷材本体と受衝部カバー体との素材はゴムからなるものであったが、これに限らない。   Furthermore, although the material of the fender body and the impact cover body is made of rubber, it is not limited thereto.

更に、上記の実施の形態では、受衝部カバー体の素材は、防舷材本体と同一のものを用いる構成であったが、異なる素材に置き替えたり、受衝部カバー体の表面に異なる素材を層のように追加したりする構成であってもよい。例えば、受衝部カバー体の表面を超高分子ポリエチレンで覆うようにしてもよい。この場合、超高分子ポリエチレンはゴム材料と比較して摩擦係数が低く、接舷時において船舶が受衝部カバー体の表面を滑りやすくなるため、船舶を傷つける虞が低減する。   Furthermore, in the above embodiment, the material of the impact cover body is the same as that of the fender main body, but may be replaced with a different material or may be different on the surface of the impact cover body. The material may be added as a layer. For example, the surface of the impact cover body may be covered with ultra-high molecular weight polyethylene. In this case, the ultra high molecular weight polyethylene has a lower coefficient of friction than the rubber material, and the ship slips easily on the surface of the impact cover body at the time of contact, thereby reducing the possibility of damaging the ship.

更に、上記の実施の形態では、新たな防舷材本体を前提としたものであったが、既存の防舷材本体にも同様に適用できる。   Furthermore, in the above embodiment, a new fender main body is premised, but the present invention can be applied to an existing fender main body as well.

尚、上記の実施の形態において、突起体や第1、第2係合部の有無にかかわらず、外力を受けたときに、受衝部カバー体が防舷材本体の受衝面に対してずれる方向へ相対移動するものとしてもよい。例えば、外力を受けた場合において、この外力における受衝面に平行な方向の成分が、防舷材本体にせん断破壊を生じさせる大きさを超えたときに、受衝部カバー体がずれる方向へ相対移動するように構成すればよい。これにより、過大な外力が作用したときに、受衝部カバー体が相対移動して外力の影響を緩和し、防舷材本体が損傷するのを回避することができる。   In the above embodiment, regardless of the presence or absence of the protrusion and the first and second engaging portions, the receiving portion cover body is against the impact receiving surface of the fender main body when receiving an external force. It is also possible to move relative to the direction of displacement. For example, when an external force is applied, if the component in the direction parallel to the impact receiving surface in the external force exceeds the size that causes shear failure in the fender body, the impact receiving portion cover body shifts in the direction It may be configured to move relatively. Thereby, when an excessive external force acts, the impact receiving part cover body relatively moves to reduce the influence of the external force, and it is possible to avoid that the fender main body is damaged.

図18は、この発明の第2の実施の形態による防舷材構造体を岸壁に取り付けた状態の斜視図であり、図19は、図18で示した防舷材構造体の分解斜視図であり、図20は、図18で示した防舷材構造体のXX−XXラインから見た断面図である。   FIG. 18 is a perspective view of the fender structure according to the second embodiment of the present invention attached to a quay, and FIG. 19 is an exploded perspective view of the fender structure shown in FIG. FIG. 20 is a cross-sectional view of the fender structure shown in FIG. 18 as seen from line XX-XX.

この実施の形態は、防舷材本体12が中空部を持たない場合でも、受衝部カバー体41を取り付けることを可能にしたものである。本例の防舷材構造体2にあっては、受衝部カバー体41が、防舷材本体12の受衝部13の表面(受衝面)14の少なくとも一部を覆うカバー本体部43と、このカバー本体部43に一体的に設けられ、岸壁80等に脱着自在に固定される支持部44とを備えるものである。これにより、支持部44を岸壁80等に固定することによって、カバー本体部43が受衝面14の少なくとも一部を覆うように、受衝部カバー体41を防舷材本体12に取り付けることが可能である。   In this embodiment, even when the fender body 12 does not have a hollow portion, the impact receiving portion cover body 41 can be attached. In the fender structure 2 of this embodiment, the impact cover portion 41 covers at least a part of the surface (impact surface) 14 of the impact portion 13 of the fender body 12. And a supporting portion 44 provided integrally with the cover main body 43 and detachably fixed to the quay 80 or the like. Thus, by fixing the support portion 44 to the quay 80 or the like, the impact cover body 41 may be attached to the fender body 12 such that the cover main body 43 covers at least a part of the impact receiving surface 14. It is possible.

更に、この実施の形態では、受衝部カバー体41が複数の第1〜5のカバーユニット42a〜42eで構成される。第1〜5のカバーユニット42a〜42eは、ほぼ同一形態に形成されるので、これらの詳細な説明を、第1のカバーユニット42aについての説明で代表させる。   Furthermore, in this embodiment, the impact part cover body 41 is comprised by several 1st-5th cover units 42a-42e. Since the first to fifth cover units 42a to 42e are formed in substantially the same form, the detailed description thereof will be represented by the description of the first cover unit 42a.

第1のカバーユニット42aは、受衝面14上に重ね合わされるカバー本体部43と、カバー本体部43における防舷材本体12の長手方向に沿う両側部に一体的に設けられた一対の支持部44とを備える。   The first cover unit 42 a includes a cover main body 43 superimposed on the impact receiving surface 14, and a pair of supports integrally provided on both sides of the cover main body 43 along the longitudinal direction of the fender main body 12. And a unit 44.

カバー本体部43は、受衝面14側の一部を収納できるように背面側を開放した断面台形状に形成される。又、防舷材本体12が長手方向を鉛直方向とするように固定される場合、最上部に位置する第1のカバーユニット42aについては、カバー本体部43aに、防舷材本体12の上端側の側面部18の一部を覆う保護部62が設けられる。この保護部62は、第2〜第5のカバーユニット42b〜42eでは省略される。   The cover main body 43 is formed in a trapezoidal cross-sectional shape in which the back side is opened so as to be able to accommodate a part on the impact surface 14 side. In addition, when the fender body 12 is fixed so that the longitudinal direction is the vertical direction, the upper end side of the fender body 12 is attached to the cover body portion 43a of the first cover unit 42a located at the top. The protection part 62 which covers a part of side part 18 of is provided. The protection portion 62 is omitted in the second to fifth cover units 42b to 42e.

支持部44は、カバー本体部43から岸壁80側へ向かって伸びるシート状の形態を有し、その先端側領域に、後述するアンカーボルト30を挿通させるための開孔57が形成される。本例では、一方の支持部44につき2個の開孔57が形成される。更に本例では、支持部44の上に配置して、岸壁80への固定状態を確実化するための押さえ部材60a〜60eが、第1〜5のカバーユニット42a〜42eの支持部44ごとに用いられる。各押さえ部材60a〜60eにもアンカーボルト30を挿通させるための開孔58が形成される。   The support portion 44 has a sheet-like form extending from the cover main body 43 toward the quay 80, and an opening 57 for inserting an anchor bolt 30 described later is formed in the front end side region. In the present example, two openings 57 are formed in one support portion 44. Furthermore, in the present embodiment, pressing members 60a to 60e are disposed on the support portion 44 to ensure the fixing state to the quay 80, for each of the support portions 44 of the first to fifth cover units 42a to 42e. Used. Openings 58 for inserting the anchor bolts 30 are also formed in the pressing members 60a to 60e.

防舷材構造体2を施工するには、図19に示すように、防舷材本体12を岸壁80にアンカーボルト25とナット26とで固定したのち、この防舷材本体12を覆うように、第1〜5のカバーユニット42a〜42eを順に岸壁80に固定する。そのため、予め岸壁80における防舷材本体12の近傍に、第1〜5のカバーユニット42a〜42eの支持部44に形成した各開孔57の位置に合わせてアンカーボルト30を埋設しておく。そして先ず、最上部に位置させる第1のカバーユニット42aのカバー本体部43を受衝部13の上に重ねると共に、支持部44を、その開孔57にアンカーボルト30を挿通させて、岸壁80の表面に配置する。次いで、この支持部44の上に、押さえ部材60aをその開孔58にアンカーボルト30を挿通させて配置する。その後、アンカーボルト30にワッシャ31を介してナット32を螺合させ、これを締め付けることにより、第1のカバーユニット42aを固定する。   In order to construct the fender structure 2, as shown in FIG. 19, the fender body 12 is fixed to the quay 80 by the anchor bolt 25 and the nut 26, and then the fender body 12 is covered. The first to fifth cover units 42a to 42e are fixed to the quay 80 in order. Therefore, the anchor bolt 30 is embedded in advance in the vicinity of the fender main body 12 in the quay 80 in accordance with the positions of the openings 57 formed in the support portions 44 of the first to fifth cover units 42a to 42e. Then, first, the cover main body 43 of the first cover unit 42a positioned at the uppermost portion is superimposed on the impact receiving portion 13, and the support bolt 44 is inserted into the opening 57 of the anchor bolt 30. Place on the surface of Subsequently, the holding member 60 a is disposed on the support portion 44 by inserting the anchor bolt 30 through the opening 58. Thereafter, the nut 32 is screwed into the anchor bolt 30 via the washer 31, and the first cover unit 42a is fixed by tightening the nut 32.

続いて第2のカバーユニット42bを上記と同様の手順で、第1のカバーユニット42aに隣接するように、岸壁80に固定する。引き続き第3〜第5のカバーユニット42c〜42eも同様の手順にてそれぞれ隣接するように順に岸壁80に固定することにより、防舷材本体12の受衝面14全体を覆う受衝部カバー体41が構成される。   Subsequently, the second cover unit 42b is fixed to the quay 80 so as to be adjacent to the first cover unit 42a in the same manner as described above. Subsequently, the third to fifth cover units 42c to 42e are also sequentially fixed to the quay 80 so as to be adjacent to each other in the same procedure, so that the impact receiving portion cover body covering the entire impact receiving surface 14 of the fender main body 12 41 are configured.

このように本例の受衝部カバー体41は、支持部44を岸壁80に固定することによって、カバー本体部43が受衝面14の少なくとも一部を覆うように、防舷材本体12に取り付けることができるものであるため、中空部を持たない防舷材本体12に対しても取り付けが可能である。   As described above, the impact portion cover body 41 of this example fixes the support portion 44 to the quay 80 so that the cover main body portion 43 covers at least a part of the impact receiving surface 14. Since it can be attached, it can be attached also to the fender body 12 having no hollow portion.

又、受衝部カバー体41を複数のカバーユニット42a〜42eで構成したので、カバーユニットの使用個数によって構成される受衝部カバー体41の大きさを変更することができる。即ち、防舷材本体12の大きさに応じた適切な個数のカバーユニットを使用することによって、長さの異なる防舷材本体12であっても、受衝面14を適切に覆うことが可能となる。具体的には、図18、19に示した防舷材本体12に対しては5つのカバーユニット42a〜42eを使用したが、これより短い防舷材本体12に対してはカバーユニットの使用個数を4つ以下に減らせばよく、反対に長い場合は、6つ以上のカバーユニットを使用することで対処できる。   Further, since the impact receiving portion cover body 41 is configured of the plurality of cover units 42a to 42e, the size of the impact receiving portion cover body 41 configured by the number of used cover units can be changed. That is, by using an appropriate number of cover units according to the size of the fender body 12, even the fender body 12 with different lengths can appropriately cover the impact surface 14. It becomes. Specifically, although five cover units 42a to 42e are used for the fender main body 12 shown in FIGS. 18 and 19, the number of cover units used for the fender main body 12 shorter than this is used. If you want to reduce it to four or less, on the contrary, if it is long, it can be dealt with by using six or more cover units.

尚、受衝部カバー体41は、防舷材本体12に対し相対移動が困難なように設けることも出来るが、外力を受けたときに、防舷材本体12の受衝面14に対してずれる方向へ相対移動することができるように構成してもよい。例えば、撓みを持たせて僅かに弛緩させた状態で支持部44を岸壁80へ固定することにより、受衝部カバー体41が外力を受けた場合に、カバー本体部43が受衝面14と平行な方向へ相対移動可能に構成することができる。このとき、受衝部カバー体41が相対移動する条件としては、例えば、作用した外力における受衝面14に平行な方向の成分が、防舷材本体12にせん断破壊を生じさせる大きさを超えた場合に設定することが考えられる。これにより、防舷材本体に過大な外力が作用したときに、受衝部カバー体41がずれる方向へ胴体移動することにより外力を緩和し、防舷材本体12が損傷するのを回避することができる。   Although the impact cover member 41 can be provided so that relative movement with respect to the fender body 12 is difficult, it is possible to provide the impact face 14 of the fender body 12 when receiving an external force. You may comprise so that relative movement can be carried out to the direction which shifts. For example, by fixing the support portion 44 to the quay 80 in a state of being slightly flexed and slightly loosened, the cover main body 43 and the impact surface 14 can receive the external force when the impact portion cover body 41 receives an external force. It can be configured to be relatively movable in parallel directions. At this time, as a condition for relative movement of the impact receiving part cover body 41, for example, the component in the direction parallel to the impact receiving surface 14 in the applied external force exceeds the size that causes the fender main body 12 to cause shear failure. It is possible to set in case of Thereby, when an excessive external force acts on the fender main body, the external force is alleviated by moving the body in the direction in which the impact receiving part cover body 41 shifts, and the fender main body 12 is prevented from being damaged. Can.

尚、支持部44を緊張させて緩みのない状態で岸壁80へ固定することにより、外力を受けても受衝部カバー体41が容易には相対移動しないように構成することもできる。   The support portion 44 may be configured to be tensioned and fixed to the quay 80 without loosening so that the impact cover member 41 does not easily move relative to each other even when receiving an external force.

図21は、この発明の第3の実施の形態による防舷材構造体を岸壁に取り付けた状態の斜視図である。図21に示す防舷材構造体3は、受衝部カバー体41を、防舷材本体12の長さに合わせて製作して単一の部材としたものである。又、受衝部カバー体41を岸壁80へ固定する際に用いられる押さえ部材60についても、防舷材本体12の長さに合わせた長尺の部材としている。本例の防舷材構造体3は、前述のカバーユニットを用いる実施の形態と比較して構成要素の個数が少なくなるので、設置時の作業工数が減少し、施工性を向上させることができる。尚、長さの異なる防舷材本体12に対しては、長さの異なる受衝部カバー体41を用意することで対応すればよい。   FIG. 21 is a perspective view of the fender structure according to the third embodiment of the present invention attached to a wharf. The fender structure 3 shown in FIG. 21 is manufactured as a single member by manufacturing the receiving portion cover body 41 in accordance with the length of the fender body 12. Further, the pressing member 60 used when fixing the impact receiving portion cover body 41 to the quay 80 is also a long member in accordance with the length of the fender main body 12. In the fender structure 3 of this example, the number of components is reduced as compared with the embodiment using the above-mentioned cover unit, so the number of operation steps at the time of installation can be reduced and the workability can be improved. . The fender body 12 having a different length may be dealt with by preparing the impact receiving part cover body 41 having a different length.

図22は、この発明の第4の実施の形態による防舷材構造体の斜視図であり、図23は、図22で示した防舷材構造体の分解斜視図であり、図24は、図22で示した防舷材構造体の水平方向の断面図である。   FIG. 22 is a perspective view of a fender structure according to a fourth embodiment of the present invention, FIG. 23 is an exploded perspective view of the fender structure shown in FIG. 22, and FIG. It is horizontal sectional drawing of the fender structure shown in FIG.

これら図22〜24に示すように、この実施の形態は、円錐台状の形態を有する防舷材本体21に対して受衝部カバー体70を取り付けて、防舷材構造体4を構成したものである。図23に示すように、本例の防舷材本体21は、先端側に円形の受衝面22を有し、基端側に全周にわたりフランジ状に形成された取付部24を有する。そして受衝部カバー体70は、このような防舷材本体21の形態に合わせて、浅い円錐台状のカバー本体部71と、その周縁部から突出するように設けられた複数本の支持部72で構成される。各支持部72の先端側には、後述するアンカーボルトを挿通させるための開孔73が形成される。   As shown in FIGS. 22 to 24, in this embodiment, the fender cover 4 is attached to the fender main body 21 having a truncated cone shape, and the fender structure 4 is configured. It is a thing. As shown in FIG. 23, the fender main body 21 of the present example has a circular impact surface 22 on the distal end side, and has a mounting portion 24 formed in a flange shape over the entire circumference on the proximal end side. The impact cover body 70 has a shallow truncated cone-like cover main body 71 and a plurality of supporting parts provided so as to protrude from the peripheral edge thereof according to the form of the fender main body 21. It consists of 72. An opening 73 for inserting an anchor bolt described later is formed on the tip end side of each support portion 72.

上記の受衝部カバー体70の取り付けは、第2、第3の実施の形態と同様の手順で行われる。即ち、防舷材本体21を岸壁80にアンカーボルト25とナット26とで固定したのち、予め岸壁80における防舷材本体21の近傍に、受衝部カバー体70の支持部72に形成した各開孔73の位置に合わせてアンカーボルト30を埋設しておく。次いで、受衝部カバー体70のカバー本体部71を受衝面22の上に重ねると共に、支持部72を、その開孔73にアンカーボルト30を挿通させて、岸壁80の表面に配置する。そして、このアンカーボルト30にワッシャ31を介してナット32を螺合させ、これを締め付けることにより、受衝部カバー体70を、防舷材本体21を覆うように、岸壁80に固定することができる。   The attachment of the impact cover body 70 described above is performed in the same procedure as in the second and third embodiments. That is, after fixing the fender main body 21 to the quay 80 with the anchor bolt 25 and the nut 26, each formed in advance on the support portion 72 of the impact cover body 70 near the fender main body 21 in the quay 80 The anchor bolt 30 is embedded according to the position of the opening 73. Next, the cover body 71 of the impact cover 70 is placed on the impact surface 22, and the support 72 is disposed on the surface of the quay 80 by inserting the anchor bolt 30 into the opening 73 thereof. Then, the nut 32 is screwed to the anchor bolt 30 via the washer 31 and tightened to fix the impact receiving part cover body 70 to the quay 80 so as to cover the fender main body 21. it can.

尚、上記の第2〜第4の実施の形態において、受衝部カバー体は、防舷材本体の受衝面の全体を覆うものであったが、受衝面の少なくとも一部を覆うものであればよい。   In the second to fourth embodiments described above, although the impact receiving portion cover body covers the entire impact receiving surface of the fender main body, it covers at least a part of the impact receiving surface. If it is

更に、上記の第3、第4の実施の形態においても、防舷材構造体が外力を受けたときに、受衝部カバー体が防舷材本体の受衝面に対してずれる方向へ相対移動するものとしてもよい。例えば、外力を受けた場合において、この外力における受衝面に平行な方向の成分が、防舷材本体にせん断破壊を生じさせる大きさを超えたときに、受衝部カバー体が防舷材本体に対してずれる方向へ相対移動するように構成することができる。   Furthermore, also in the third and fourth embodiments described above, when the fender structure is subjected to an external force, the impact receiving part cover body is in the direction of being displaced relative to the impact receiving face of the fender main body. It is also possible to move. For example, when an external force is applied, when the component in the direction parallel to the impact receiving surface under the external force exceeds a size that causes the fender main body to cause a shear failure, the impact receiving portion cover body is a fender It can be configured to move relative to the body in the direction of displacement.

更に、上記の第2〜第4の実施の形態において、受衝部カバー体の裏面に複数の突起体を設けてもよい。この場合、突起体は半球形状のものでもよく、別の形状であってもよい。   Furthermore, in the second to fourth embodiments described above, a plurality of protrusions may be provided on the back surface of the impact portion cover body. In this case, the protrusion may have a hemispherical shape or may have another shape.

更に、上記の第2〜第4の実施の形態において、防舷材本体の受衝部に第1係合部を設け、受衝部カバー体に第2係合部を設ける構成としてもよい。この場合、第1係合部及び第2係合部は、一方を凹形状、他方を凸形状に形成してもよい。第1係合部及び第2係合部の個数は、例えば4つずつでもよいが、少なくとも1つずつ設けられていればよい。第1係合部及び第2係合部は、受衝面に平行な方向の力が受衝部カバー体に加わった時に、防舷材本体にせん断破壊を生じさせる前に、受衝部カバー体の第2係合部がせん断破壊されるように設定してもよい。これにより、防舷材本体の破損のおそれが低減する。   Furthermore, in the second to fourth embodiments described above, the impact receiving portion of the fender main body may be provided with the first engaging portion, and the impact receiving portion cover body may be provided with the second engaging portion. In this case, one of the first engagement portion and the second engagement portion may be formed in a concave shape, and the other may be formed in a convex shape. The number of first engagement portions and the number of second engagement portions may be four, for example, but may be at least one. The first engaging portion and the second engaging portion are configured to receive the impact cover before causing the fender body to shear when the force in the direction parallel to the impact surface is applied to the impact cover body. The second engagement portion of the body may be set to be sheared. This reduces the risk of damage to the fender body.

更に、上記の第2、第3の実施の形態において、受衝部カバー体の長手方向の両端部、又は長手方向の端部の少なくとも一方に、保護部材を設けてもよい。この場合、保護部材は、防舷材本体の側面部であって受衝部側の一部又は側面部の全面を覆う構成としてもよい。   Furthermore, in the second and third embodiments described above, protective members may be provided on at least one of the longitudinal ends or the longitudinal ends of the impact cover body. In this case, the protective member may be a side surface portion of the fender main body, and may be configured to cover a part of the impact receiving portion side or the entire surface of the side surface portion.

更に、上記の第2、第3の実施の形態において、受衝部カバー体の長手方向の端部の少なくとも一方に設けられる保護部を肉厚に形成して、耐摩耗性を向上させてもよい。この場合、保護部は、第1の実施の形態の保護部材のような形態としてもよい。   Furthermore, in the second and third embodiments described above, even if the protective portion provided on at least one of the end portions in the longitudinal direction of the impact receiving portion cover body is formed thick, the abrasion resistance is improved. Good. In this case, the protective portion may be in the form of the protective member of the first embodiment.

更に、上記の第2、第3の実施の形態では、受衝部カバー体は正面視矩形形状且つ平面視略台形形状のものであったが、その他の形状であってもよい。   Furthermore, in the second and third embodiments described above, the impact receiving part cover body has a rectangular shape in a front view and a substantially trapezoidal shape in a plan view, but may have other shapes.

更に、上記の第2〜第4の実施の形態において、防舷材本体及び受衝部カバー体はゴムからなるものであったが、これに限らない。又、受衝部カバー体及び防舷材本体は、同一の素材でも、異なるものでもよい。   Furthermore, in the above second to fourth embodiments, the fender main body and the impact receiving part cover body are made of rubber, but the present invention is not limited to this. Further, the impact cover body and the fender body may be the same material or different ones.

更に、上記の第2〜第4の実施の形態において、受衝部カバー体の表面に異なる素材を層状に付加する構成であってもよい。例えば、受衝部カバー体の表面を超高分子ポリエチレン層で被覆するように構成してもよい。超高分子ポリエチレンはゴム材料と比較して摩擦係数が低く、接舷時において船舶が受衝部カバー体の表面を滑りやすくなるため、これで被覆すると、船舶を傷つける虞が低減する。   Furthermore, in the second to fourth embodiments described above, different materials may be added in layers to the surface of the impact portion cover body. For example, the surface of the impact portion cover body may be covered with the ultrahigh molecular weight polyethylene layer. The ultrahigh molecular weight polyethylene has a lower coefficient of friction than a rubber material, and the ship slips easily on the surface of the impact cover body at the time of contact, so covering with this reduces the risk of damaging the ship.

更に、上記の第2〜第4の実施の形態は、新たな防舷材本体を前提とするものでもよいが、既存の防舷材本体にも同様に適用することができる。   Furthermore, although the second to fourth embodiments described above may be premised on a new fender body, the present invention can be applied to existing fender bodies as well.

更に、上記の第2、3の実施形態において、防舷材本体は、中空部を有するものであってもよく、断面V字形であってもよい。この場合、紐状部材と紐状部材固定具とからなる固定部材を更に備えてもよい。固定部材は、帯とバックルとからなるもののほか、例えばワイヤーとフック等とで構成してもよい。紐状部材は、ゴムや樹脂によって被覆した筒状体や、ゴムや樹脂からなる筒状体によって覆ったりしてもよい。固定部材の紐状部材と紐状部材固定具とが固定される位置は、防舷材本体の中空部の一方の開口付近のほか、中空部の中央付近等、他の位置としてもよい。   Furthermore, in the second and third embodiments described above, the fender body may have a hollow portion and may have a V-shaped cross section. In this case, a fixing member consisting of a string-like member and a string-like member fastener may be further provided. The fixing member may be composed of, for example, a wire and a hook as well as the band and the buckle. The string-like member may be covered with a tubular body covered with rubber or resin, or a tubular body made of rubber or resin. The position where the string-like member of the fixing member and the string-like member fastener are fixed may be another position such as near the center of the hollow portion besides the vicinity of one opening of the hollow portion of the fender body.
