Description

防舷材の交換方法How to change fenders
　この発明は防舷材の交換方法に関し、特に船舶が接舷する際に岸壁に設置して用いられる防舷材の交換方法に関するものである。 The present invention relates to a method of replacing fenders, and more particularly to a method of replacing fenders installed and used on a quay when a ship is connected.
　図３６は、従来の防舷材の交換方法に関連する防舷材構造体を示す概略斜視図である。 FIG. 36 is a schematic perspective view showing a fender structure relating to a conventional fender replacement method.
　図を参照して、従来の防舷材構造体７２は、船舶の接舷のために岸壁７に設置して用いられるものであって、ゴム材料からなり、開口７６が設けられた平面視略台形形状を有して垂直方向に延び、接舷する船舶に当接する受衝部７４と、受衝部７４に接続され、垂直方向に延びる一対の支衝部７７ａ及び７７ｂとから構成される。 With reference to the drawing, the conventional fender structure 72 is used by being installed on the quay 7 for contact of a ship, is made of a rubber material, and has an opening 76. The impact portion 74 has a trapezoidal shape, extends in the vertical direction, and contacts the vessel to be connected, and a pair of abutment portions 77a and 77b connected to the impact portion 74 and extending in the vertical direction.
　防舷材構造体７２の支衝部７７ａは、ボルト７９ａ～７９ｄを介して岸壁７に固定されている。同様に、防舷材構造体７２の支衝部７７ｂは、図示しないボルトを介して岸壁７に固定されている。 The bearing portion 77a of the fender structure 72 is fixed to the quay 7 via bolts 79a to 79d. Similarly, the support portion 77b of the fender structure 72 is fixed to the quay 7 via a bolt (not shown).
　図３７は、図３６で示した防舷材構造体の使用状態を示す概略平面図であって、小型船舶用の防舷材構造体と大型船舶用の防舷材構造体とが交互に隣接して岸壁に設置された状態を示す図である。 FIG. 37 is a schematic plan view showing the state of use of the fender structure shown in FIG. 36, in which fender structures for small vessels and fender structures for large vessels are alternately adjacent to each other. It is a figure which shows the state installed in the quay.
　図を参照して、いわゆる通常の船舶に対応した小型船舶用の防舷材構造体７１ａと、防舷材構造体７１ａの右方側に隣接し、いわゆる大型観光客船舶に対応した大型船舶用の防舷材構造体７２ａと、防舷材構造体７２ａの右方側に隣接した小型船舶用の防舷材構造体７１ｂと、防舷材構造体７１ｂの右方側に隣接した大型船舶用の防舷材構造体７２ｂとが各々、岸壁７に固定設置されている。 Referring to the figure, a fender structure 71a for a small ship corresponding to a so-called ordinary ship and a large ship corresponding to a so-called large tourist ship adjacent to the right side of the fender structure 71a. Of the fender structure 72a, a fender structure 71b for a small vessel adjacent to the right side of the fender structure 72a, and a large vessel adjacent to the right side of the fender structure 71b The fender structure 72b is fixedly installed on the quay 7.
　防舷材構造体７１ａ及び７１ｂは、図３６で示した防舷材構造体７２と同一構成であるが、防舷材構造体７２に比べて全体の大きさを小さくしたものである。防舷材構造体７１ａ及び７１ｂは、その受衝部７３ａ及び７３ｂが岸壁７から第１の距離Ｌ１を有するように岸壁７に固定設置されている。 The fender structures 71a and 71b have the same configuration as the fender structure 72 shown in FIG. 36, but the overall size is smaller than that of the fender structure 72. Fender structure 71a and 71b, the impact receiving portion 73a and 73b are fixedly installed on the quay 7 so as to have a first distance L 1 from the quay 7.
　防舷材構造体７２ａ及び７２ｂは、その受衝部７４ａ及び７４ｂが岸壁７から第２の距離Ｌ２を有するように岸壁７に固定設置されている。尚、第２の距離Ｌ２は、第１の距離Ｌ１よりも大きい。 Fender structure 72a and 72b, the impact receiving portion 74a and 74b are fixedly installed on the quay 7 to have a second distance L 2 from the quay 7. Incidentally, the second distance L 2 is greater than the first distance L 1.
　使用に際して、図示しない大型船舶が接舷するとき、大型船舶は、図３７に示した二点鎖線において防舷材構造体７２ａ及び７２ｂの受衝部７４ａ及び７４ｂに当接する。 In use, when a large vessel (not shown) comes into contact, the large vessel abuts on the impact parts 74a and 74b of the fender structural members 72a and 72b along the two-dot chain line shown in FIG.
　上記のような岸壁７において、図示しない小型船舶が接舷するとき、小型船舶は、図３７に示した破線において防舷材構造体７１ａ及び７１ｂの受衝部７３ａ及び７３ｂに当接することになる。しかし、小型船舶は、防舷材構造体７１ａ及び７１ｂの受衝部７３ａ及び７３ｂに当接する前に、防舷材構造体７２ａ及び７２ｂの受衝部７４ａ及び７４ｂに当接してしまう虞があった。そのため、図３７で示したような大型船舶用の防舷材構造体７２ａ及び７２ｂが設置されている岸壁７には、小型船舶は接舷できないことがあった。 In the quay 7 as described above, when a small ship (not shown) comes into contact, the small ship will abut on the impact receiving parts 73a and 73b of the fender structure 71a and 71b in the broken line shown in FIG. . However, there is a risk that the small-sized vessel will abut against the impact parts 74a and 74b of the fender constructions 72a and 72b before coming into contact with the impact parts 73a and 73b of the fender constructions 71a and 71b. The Therefore, the small boat can not be connected to the quay 7 on which the fender structures 72a and 72b for a large boat as shown in FIG. 37 are installed.
　そこで、上述の課題を解決するものとして、次に示すような岸壁７がある。 Then, there exist quay walls 7 as shown below as a thing which solves the above-mentioned subject.
　図３８は、図３６で示した防舷材構造体のその他の使用状態を示す概略平面図であって、小型船舶用の防舷材構造体の群と大型船舶用の防舷材構造体の群とが別々に岸壁に設置された状態を示す図である。 FIG. 38 is a schematic plan view showing another state of use of the fender structure shown in FIG. 36, which is a group of fender structures for small vessels and a fender structure for large vessels. It is a figure which shows the state in which the group was separately installed in the quay.
　図を参照して、小型船舶用の防舷材構造体７１ａと、防舷材構造体７１ａの右方側に隣接して小型船舶用の防舷材構造体７１ｂとが各々、岸壁７に固定設置されている。防舷材構造体７１ｂの右方側に隣接して大型船舶用の防舷材構造体７２ａと、防舷材構造体７２ａの右方側に隣接して大型船舶用の防舷材構造体７２ｂとが各々、岸壁７に固定設置されている。即ち、小型船舶用の防舷材構造体７１ａ及び７１ｂは岸壁７の左方側に、大型船舶用の防舷材構造体７２ａ及び７２ｂは岸壁７の右方側にそれぞれ群として設置されている。 Referring to the figure, a fender structure 71a for a small vessel and a fender structure 71b for a small vessel adjacent to the right side of the fender structure 71a are fixed to the wharf 7, respectively. is set up. A fender structure 72a for a large vessel adjacent to the right side of the fender structure 71b, and a fender structure 72b for a large vessel adjacent to the right side of the fender structure 72a And are each fixedly installed on the quay 7. That is, the fender structures 71a and 71b for small vessels are installed as a group on the left side of the quay 7, and fender structures 72a and 72b for large vessels are installed as a group on the right of the quay 7 respectively. .
　使用に際して、図示しない小型船舶は、図３８で示した破線において防舷材構造体７１ａ及び７１ｂの受衝部７３ａ及び７３ｂに当接するように接舷する。一方、図示しない大型船舶は、図３８で示した二点鎖線において防舷材構造体７２ａ及び７２ｂの受衝部７４ａ及び７４ｂに当接するように接舷する。 In use, the small vessel (not shown) is in contact with the impact receiving parts 73a and 73b of the fender structure 71a and 71b at the broken line shown in FIG. On the other hand, a large ship (not shown) is in contact with the impact receiving parts 74a and 74b of the fender structure 72a and 72b in the two-dot chain line shown in FIG.
　ここで、小型船舶は、大型船舶用の防舷材構造体７２ａ及び７２ｂを使用することはできない。小型船舶は、大型船舶に比べて、岸壁７に接舷する頻度が高いにも関わらず、防舷材構造体７２ａ及び７２ｂが設置されている岸壁７には接舷できないため、不便が生じていた。 Here, small vessels can not use the fender structures 72a and 72b for large vessels.

　尚、小型船舶用の防舷材構造体７１ａ及び７１ｂは、図３７で示した従来の小型船舶用の防舷材構造体７１ａ及び７１ｂと同一である。ここでは、説明を繰り返さない。 The fender structures 71a and 71b for small vessels are the same as the conventional fender structures 71a and 71b for small vessels shown in FIG. Here, the description will not be repeated.
　図１の（１）を参照して、第１の防舷材構造体である、いわゆる通常の船舶に対応した小型船舶用の防舷材構造体７１ａと、第２の防舷材構造体である、防舷材構造体７１ａの右方側に隣接し、いわゆる大型観光客船舶に対応した大型船舶用の防舷材構造体１１ａと、防舷材構造体１１ａの右方側に隣接した小型船舶用の防舷材構造体７１ｂと、防舷材構造体７１ｂの右方側に隣接した大型船舶用の防舷材構造体１１ｂとが各々、岸壁７に固定設置されている。 Referring to (1) of FIG. 1, it is a first fender structure, that is, a fender structure 71a for small vessels corresponding to a so-called ordinary ship, and a second fender structure. There is a fender structure 11a adjacent to the right side of the fender structure 71a and a small structure adjacent to the right side of the fender structure 11a for a so-called large tourist vessel, A fender structure 71b for ships and a fender structure 11b for a large ship adjacent to the right side of the fender structure 71b are respectively fixedly installed on the quay 7.
　防舷材構造体７１ａ及び７１ｂは、その受衝部７３ａ及び７３ｂが岸壁７から第１の距離Ｌ１を有するように岸壁７に固定設置されている。 Fender structure 71a and 71b, the impact receiving portion 73a and 73b are fixedly installed on the quay 7 so as to have a first distance L 1 from the quay 7.
　防舷材構造体１１ａ及び１１ｂは、後述する、その受衝部４３ａ及び４３ｂが岸壁７から第２の距離Ｌ２を有するように岸壁７に固定設置されている。尚、第２の距離Ｌ２は、第１の距離Ｌ１よりも大きい。又、防舷材構造体１１ａ及び１１ｂの受衝部４３ａ（後述する防舷材本体４１ａ）及び４３ｂ（後述する防舷材本体４１ｂ）は、後述するガイド２１ａ～２１ｄに脱着自在に取り付けられている。 Fender structures 11a and 11b will be described later, the impact receiving portion 43a and 43b are fixedly installed on the quay 7 to have a second distance L 2 from the quay 7. Incidentally, the second distance L 2 is greater than the first distance L 1. Also, the impact receiving parts 43a of the fender structure 11a and 11b (fender main body 41a described later) and 43b (fender main body 41b described later) are detachably attached to guides 21a to 21d described later. There is.
　後述する防舷材構造体１１ａ及び１１ｂのガイド２１ａ～２１ｄは、岸壁７から第３の距離Ｌ３を有するように岸壁７に固定設置されている。尚、第３の距離Ｌ３は、第１の距離Ｌ１よりも小さい。このように構成した理由については後述する。 The guides 21a to 21d of the fender structure 11a and 11b described later are fixedly installed on the quay 7 so as to have a third distance L3 from the quay 7. The third distance L 3 is smaller than the first distance L 1. The reason for this configuration will be described later.
　使用に際して、図示しない大型船舶が接舷するとき、大型船舶は、図１の（１）に示した二点鎖線において防舷材構造体１１ａ及び１１ｂの受衝部４３ａ及び４３ｂに当接する。 In use, when a large vessel (not shown) comes into contact, the large vessel abuts on the impact receiving parts 43a and 43b of the fender structure 11a and 11b at the two-dot chain line shown in (1) of FIG.
　図１の（２）を参照して、図１の（１）において、後述する防舷材構造体１１ａの防舷材本体４１ａを、ガイド２１ａ及び２１ｂから取り外した状態である。又、図１の（１）において、防舷材構造体１１ｂの受衝部４３ｂを、防舷材構造体１１ｃの受衝部４３ｃに置き換えた状態である。尚、防舷材構造体１１ｃは、その受衝部４３ｃが岸壁７から第１の距離Ｌ１を有するように岸壁７に固定設置されている。 Referring to (2) of FIG. 1, in (1) of FIG. 1, a fender main body 41 a of a fender structure 11 a described later is removed from the guides 21 a and 21 b. Further, in FIG. 1 (1), the impact receiving portion 43b of the fender structure 11b is replaced with the impact portion 43c of the fender structure 11c. Incidentally, fender structure 11c, the impact receiving portion 43c is fixedly installed on the quay 7 so as to have a first distance L 1 from the quay 7.
　使用に際して、図示しない小型船舶は、図１の（２）に示した破線において防舷材構造体７１ａ及び７１ｂの受衝部７３ａ及び７３ｂと、防舷材構造体１１ｃの受衝部４３ｃとに、当接することになる。このとき、防舷材構造体１１ａ及び１１ｃのガイド２１ａ～２１ｄは、第１の距離Ｌ１よりも小さい第３の距離Ｌ３を岸壁７から有しているので、小型船舶がガイド２１ａ～２１ｄに当接する虞はない。 In use, the small vessel (not shown) is shown by broken lines shown in FIG. 1 (2) in the impact receiving portions 73a and 73b of the fender structure 71a and 71b and the impact portion 43c of the fender structure 11c. , Will abut. At this time, the guide 21a ~ 21d of the fender structure 11a and 11c, because the first distance L third distance L 3 is smaller than 1 has the quay 7, a small boat guide 21a ~ 21d There is no risk of contact with
　よって、大型船舶が接舷する際には、図１の（１）で示した状態に第２の防舷材構造体である防舷材構造体１１ａ及び１１ｂを岸壁７に設置して、通常の小型船舶が接舷する際には、図１の（２）で示した状態に、防舷材構造体１１ａ及び１１ｃを変更することで対応できる。従って、第２の防舷材構造体である、第１の距離Ｌ１よりも大きい第２の距離Ｌ２を有する防舷材構造体１１ａの受衝部４３ａ（防舷材本体４１ａ）は、岸壁７に取り付けられたガイド２１ａ及び２１ｂから取り外すことができるため、接舷する船舶の大きさ等に応じて、適切な防舷材構造体を選択できると共に、岸壁７の使用態様が拡大する。 Therefore, when a large ship is in contact, the fender constructions 11a and 11b, which are the second fender constructions, are installed in the quay 7 in the state shown in (1) of FIG.

Therefore, it becomes possible to select an appropriate fender structure according to the size and the like of the ship to be connected. The specific steps of the method of replacing the fender body will be described later.
　使用に際して、図５を参照して、防舷材構造体１１の防舷材本体４１の支衝部４７ａ及び４７ｂの一部が、ガイド２１ａ及び２１ｂの隙間２２ａ及び２２ｂを介してガイド２１ａ及び２１ｂに係合するように脱着自在に設置される。 In use, referring to FIG. 5, a part of the support portions 47a and 47b of the fender main body 41 of the fender structure 11 is guided by the guides 21a and 21b via the gaps 22a and 22b between the guides 21a and 21b. It is releasably installed to engage with the
　以上、この実施の形態による防舷材の交換方法に関連する防舷材構造体１１は、上述したように構成されているが、防舷材の交換方法は具体的には以下のような工程となる。ここでは、図１の（１）における防舷材構造体１１ｂの受衝部４３ｂ（防舷材本体４１ｂ）を、図１の（２）における防舷材構造体１１ｃの受衝部４３ｃ（防舷材本体４１ｃ）に入れ替えることに当てはめて説明する。又、以降の他の実施の形態においても、防舷材本体４１ｂを防舷材本体４１ｃに入れ替えることに当てはめて説明する。 As mentioned above, although the fender structure 11 related to the fender replacement method according to this embodiment is configured as described above, the fender replacement method is specifically the following steps. It becomes. Here, the impact receiving portion 43b (the fender main body 41b) of the fender structure 11b in (1) of FIG. 1 is the same as the impact portion 43c of the fender structure 11c in (2) of FIG. It applies to changing to the main material 41c) of a covering material, and demonstrates. Moreover, also in the other following embodiments, it applies to replacing the fender main body 41b with the fender main body 41c.
　図１から図４を再度参照して、上述したように、防舷材構造体１１ｂは、岸壁７に固定され、互いに対向する一対のガイドであるガイド２１ｃ及び２１ｄに対して垂直方向に脱着自在に係合する防舷材本体である防舷材本体４１ｂが取り付けられている。又、ガイド２１ｃ及び２１ｄは垂直方向に延びると共に、その下端には水平方向に延びるストッパー３１が取り付けられており、防舷材本体４１ｂの下方への移動を阻止している。 Referring again to FIGS. 1 to 4, as described above, the fender structure 11b is fixed to the quay 7, and can be vertically detached from the guides 21c and 21d, which are a pair of guides facing each other. A fender main body 41b, which is a fender main body, is attached. The guides 21c and 21d extend in the vertical direction, and a horizontally extending stopper 31 is attached to the lower end of the guides 21c and 21d to prevent the downward movement of the fender body 41b.
　まず、防舷材本体４１ｂを取り出す第１工程として、図示しないクレーン等から延びる図示しないワイヤー等を、防舷材本体４１ｂの開口４４ｂの内側と受衝部４３ｂの外側の上端から下端までを垂直方向に通るようにして、輪のようにして取り付ける。その後、クレーン等により防舷材本体４１ｂを吊り上げて、ガイド２１ｃ及び２１ｄから図２の矢印で示した方向の逆方向に引き抜くようにして取り出す。 First, as a first step of taking out the fender body 41b, a wire or the like (not shown) extending from a crane or the like (not shown) is vertically vertical from the upper end to the lower end of the inside of the opening 44b of the fender body 41b and the outer side of the impact receiving portion 43b. Pass in the direction and attach like a ring. Thereafter, the fender main body 41b is lifted by a crane or the like and taken out from the guides 21c and 21d in a direction opposite to the direction shown by the arrow in FIG.
　この際、防舷材本体４１ｂはボルト等で岸壁７に直接固定されていないため、従来の防舷材の交換方法のように、足場を組み、その上でボルト等を取り外すは必要ない。 At this time, since the fender main body 41b is not directly fixed to the quay 7 by bolts or the like, it is not necessary to set up a scaffold and remove the bolts or the like on it as in the conventional fender replacement method.
　次に、新たな防舷材本体である防舷材本体４１ｃを取り付ける第２工程として、防舷材本体４１ｂを取り外した後は、防舷材本体４１ｃを防舷材本体４１ｂと同様にクレーン等を介して吊り下げて、ガイド２１ｃ及び２１ｄの上方から図２の矢印で示した方向に差し込み、ガイド２１ｃ及び２１ｄに係合するように取り付ける。この時に、ガイド２１ｃ及び２１ｄと防舷材本体４１ｃとの滑りをよくするために、図示しない水や潤滑剤を用いても良い。防舷材本体４１ｃは、その下端がガイド２１ｃ及び２１ｄのストッパー３１の上端に当接するまで降下し、ストッパー３１によって防舷材本体４１ｃのそれ以上の下方への移動が阻止される。 Next, as a second step of attaching the fender body 41c, which is a new fender body, after removing the fender body 41b, the fender body 41c may be a crane or the like in the same manner as the fender body 41b. , And inserted from above the guides 21c and 21d in the direction indicated by the arrow in FIG. 2 and attached so as to engage with the guides 21c and 21d. At this time, in order to improve the sliding between the guides 21c and 21d and the fender main body 41c, water or a lubricant (not shown) may be used. The fender body 41c is lowered until its lower end abuts on the upper ends of the stoppers 31 of the guides 21c and 21d, and the stopper 31 prevents further downward movement of the fender body 41c.
　この際、防舷材本体４１ｃは、ガイド２１ｃ及び２１ｄによって取付け位置が予め決まっているので、取付け時に位置合わせを再度行う必要はない。又、防舷材本体４１ｃは、ガイド２１ｃ及び２１ｄを介して岸壁に係合するため、足場の上でボルト等で固定する必要もない。 At this time, since the attachment position of the fender main body 41c is predetermined by the guides 21c and 21d, it is not necessary to perform alignment again at the time of attachment. Further, since the fender body 41c is engaged with the quaywall via the guides 21c and 21d, it is not necessary to fix it with bolts or the like on the scaffold.
　最後に、防舷材本体４３ｃに取り付けたワイヤー等を取り外して、防舷材の交換は完了する。 Finally, the wire or the like attached to the fender main body 43c is removed to complete the replacement of the fender.
　このように構成すると、防舷材本体４１ｂ及び４１ｃはガイド２１ｃ及び２１ｄを介して岸壁７に設置されるため、足場の設置や固定用のボルトの取り外し及び取り付け等の工程が不要となり、防舷材の交換時の作業効率が向上する。又、防舷材本体４１ｂ及び４１ｃの下端の一部がストッパー３１の一部と当接するため、防舷材本体４１ｂ及び４１ｃがガイド２１ｃ及び２１ｄの下端から落下しない。 According to this structure, the fender main bodies 41b and 41c are installed on the quay 7 through the guides 21c and 21d, thereby eliminating the need for steps such as removing and attaching bolts for installing and fixing the scaffold, Work efficiency at the time of material replacement improves. In addition, since a part of the lower ends of the fender main bodies 41b and 41c abuts on a part of the stopper 31, the fender main bodies 41b and 41c do not fall from the lower ends of the guides 21c and 21d.
　図１４は、この発明の第２の実施の形態による防舷材の交換方法に関連する防舷材構造体の防舷材本体を示す概略正面図であって、図１０に対応した図であり、図１５は、図１４で示した防舷材本体の概略右側面図であって、図１２に対応した図であり、図１６は、図１４で示したＸＶＩ－ＸＶＩラインから見た概略断面図であって、図１３に対応した図である。 FIG. 14 is a schematic front view showing a fender body of a fender structure relating to a method of replacing a fender according to a second embodiment of the present invention, the view corresponding to FIG. 15 is a schematic right side view of the fender body shown in FIG. 14 corresponding to FIG. 12, and FIG. 16 is a schematic cross section viewed from the XVI-XVI line shown in FIG. It is a figure, Comprising: It is a figure corresponding to FIG.
　尚、この第２の実施の形態による防舷材の交換方法に関連する防舷材構造体１２は、図２で示した第１の実施の形態による防舷材の交換方法に関連する防舷材構造体１１と基本的な構成は同一である。ここでは、その相違点を中心に説明する。 The fender structure 12 related to the fender replacement method according to the second embodiment is a fender related to the fender replacement method according to the first embodiment shown in FIG. The basic configuration is the same as that of the material structure 11. Here, the differences will be mainly described.
　これらの図を参照して、防舷材構造体１２の防舷材本体４１は、受衝部４３と、後述するスタッドボルト５４ａ～５４ｆと係合する開口４９ａ～４９ｆが形成された支衝部４７ａ及び４７ｂと、スタッドボルト５４ａ～５４ｆが設置され、防錆性を有するステンレス鋼板等からなる平板形状を有する基板５３とから構成される。 Referring to these drawings, the fender main body 41 of the fender structure 12 has a receiving portion 43 and a supporting portion having openings 49a to 49f engaged with stud bolts 54a to 54f described later. 47a and 47b, and stud bolts 54a to 54f are provided, and they are composed of a substrate 53 having a flat plate shape made of a stainless steel plate or the like having corrosion resistance.
　又、基板５３の支衝部４７ａ及び４７ｂ側の面の上部には、金属製の丸棒等をコの字形状に折り曲げる等して形成した、防舷材本体４１を吊るすための一対の連結部５６ａ及び５６ｂが、横並びで取り付けられている。 In addition, a pair of connections for suspending the fender main body 41 formed by bending a metal round bar or the like in a U-shape on the upper part of the surface on the support portions 47a and 47b side of the substrate 53 The parts 56a and 56b are mounted side by side.
　防舷材構造体１２の支衝部４７ａ及び４７ｂは、ナット５５ａ～５５ｆと螺合したスタッドボルト５４ａ～５４ｆを介して基板５３に当接して一体的に取り付けられている。 The bearing portions 47a and 47b of the fender structure 12 are integrally attached in contact with the substrate 53 via stud bolts 54a to 54f screwed with the nuts 55a to 55f.
　使用に際して、図５と同様にして、防舷材構造体１２の防舷材本体４１の支衝部４７ａ及び４７ｂの一部と基板５３の一部とが、ガイド２１ａ及び２１ｂの隙間２２ａ及び２２ｂを介してガイド２１ａ及び２１ｂに係合するように脱着自在に設置される。 In use, in the same manner as in FIG. 5, a part of the support portions 47a and 47b of the fender main body 41 of the fender structure 12 and a part of the substrate 53 form the gaps 22a and 22b between the guides 21a and 21b. Are detachably installed so as to engage with the guides 21a and 21b.
　従って、防舷材構造体１２の防舷材本体４１の支衝部４７ａ及び４７ｂの一部が基板５３の一部によって固定されるため、防舷材構造体１２のガイド２１ａ及び２１ｂへの設置が容易となる。 Therefore, since a part of the support portions 47a and 47b of the fender main body 41 of the fender structure 12 is fixed by a part of the substrate 53, installation of the fender structure 12 on the guides 21a and 21b Becomes easy.
　以上のように、この実施の形態による防舷材の交換方法に関連する防舷材構造体１２は構成されているが、防舷材の交換方法は以下のような工程となる。 As described above, although the fender structure 12 related to the fender replacement method according to this embodiment is configured, the fender replacement method is the following steps.
　尚、この実施の形態の防舷材の交換方法の基本的な工程は第１の実施の形態と同様であるため、ここでは相違点を中心に説明する。 The basic steps of the method of replacing fenders of this embodiment are the same as those of the first embodiment, and therefore, the differences will be mainly described here.
　図１及び図１４から図１６を再度参照して、第１の実施の形態では、防舷材本体４１ｂを取り出す第１工程と、防舷材本体４１ｃを取り付ける第２工程とのいずれにおいても、防舷材本体４１ｂ及び４１ｃの吊り上げ及び吊り下げを行うために、図示しないワイヤー等を防舷材本体４１ｂ及び４１ｃの開口４４ｂの内側と受衝部４３ｂの外側の上端から下端までを垂直方向に通るようにして、輪のようにして取り付けていた。しかしながら、この実施の形態では、防舷材本体４１ｂ及び４１ｃはそれぞれ、連結部５６ａ及び５６ｂを備えた基板５３と固定されている。これにより、第１工程及び第２工程のいずれにおいても、図示しないワイヤー等を防舷材本体４１ｂ及び４１ｃの連結部５６ａ及び５６ｂの各々に連結させて、基板５３ごと吊り上げ及び吊り下げを行うことができる。 Referring again to FIGS. 1 and 14 to 16, in the first embodiment, in both the first step of taking out the fender body 41 b and the second step of attaching the fender body 41 c, In order to lift and suspend the fender main bodies 41b and 41c, wires (not shown) are vertically arranged from the upper end to the lower end of the inside of the opening 44b of the fender main bodies 41b and 41c and the outer side of the impact receiving portion 43b. It passed through and was attached like a ring. However, in this embodiment, the fender main bodies 41b and 41c are fixed to the substrate 53 provided with the connecting portions 56a and 56b, respectively. Thus, in any of the first step and the second step, a wire or the like (not shown) is connected to each of the connection portions 56a and 56b of the fender members 41b and 41c, and the whole substrate 53 is lifted and suspended. Can.
　従って、連結部５６ａ及び５６ｂを介しての防舷材本体４１ｂ及び４１ｃの吊り上げ及び吊り下げ移動が可能となるため、ワイヤー等の連結作業が容易となり、防舷材の交換時の作業効率が向上する。又、連結部５６ａ及び５６ｂは基板５３の支衝部４７ａ及び４７ｂ側の面の上部に取り付けられているため、潮位が高い状態でも防舷材の交換が容易となる。 Accordingly, lifting and suspending movement of the fender main bodies 41b and 41c through the connecting portions 56a and 56b can be performed, so connection work of a wire or the like is facilitated, and work efficiency at the time of fender replacement is improved. Do. Further, since the connection parts 56a and 56b are attached to the upper part of the surface on the side of the support parts 47a and 47b of the substrate 53, replacement of the fenders becomes easy even in a high tide state.
　図１７は、この発明の第３の実施の形態による防舷材の交換方法に関連する防舷材構造体の防舷材本体を示す概略正面図であって、図１０に対応した図であり、図１８は、図１７で示した防舷材本体の概略右側面図であって、図１２に対応した図であり、図１９は、図１７で示したＸＩＸ－ＸＩＸラインから見た概略断面図であって、図１３に対応した図である。 FIG. 17 is a schematic front view showing a fender body of a fender structure relating to a method of replacing fenders according to a third embodiment of the present invention, the view corresponding to FIG. FIG. 18 is a schematic right side view of the fender body shown in FIG. 17, corresponding to FIG. 12, and FIG. 19 is a schematic cross section viewed from the XIX-XIX line shown in FIG. It is a figure, Comprising: It is a figure corresponding to FIG.
　尚、この第３の実施の形態による防舷材の交換方法に関連する防舷材構造体１３は、図１４で示した第２の実施の形態による防舷材の交換方法に関連する防舷材構造体１２と基本的な構成は同一である。ここでは、その相違点を中心に説明する。 The fender structure 13 related to the fender replacement method according to the third embodiment is a fender related to the fender replacement method according to the second embodiment shown in FIG. The basic configuration is the same as that of the material structure 12. Here, the differences will be mainly described.
　これらの図を参照して、防舷材構造体１３の防舷材本体４１の支衝部４７ａ及び４７ｂは、その内部において平板部４８ａ及び４８ｂを有していない。又、防舷材構造体１３の支衝部４７ａ及び４７ｂは、図１４で示した防舷材構造体１２において、正面視左右外方側の端部がなくなって短くなり、左右外方側の端部には基板５３のみがある。防舷材構造体１３の支衝部４７ａ及び４７ｂは、基板５３に接着剤等によって一体化して取り付けられている。 Referring to these drawings, support portions 47a and 47b of fender main body 41 of fender structure 13 do not have flat portions 48a and 48b inside. Further, in the fender structure 12 shown in FIG. 14, the abutment portions 47 a and 47 b of the fender structure 13 are shortened because the end portions on the left and right outward sides in front view are eliminated and the left and right outward sides are shortened. There is only a substrate 53 at the end. The supporting portions 47 a and 47 b of the fender structure 13 are integrally attached to the substrate 53 by an adhesive or the like.
　使用に際して、図５と同様にして、防舷材構造体１３の防舷材本体４１の基板５３の一部が、ガイド２１ａ及び２１ｂの隙間２２ａ及び２２ｂを介してガイド２１ａ及び２１ｂに係合するように脱着自在に設置される。 In use, as in FIG. 5, a part of the substrate 53 of the fender main body 41 of the fender structure 13 engages the guides 21a and 21b via the gaps 22a and 22b between the guides 21a and 21b. It is installed in a detachable manner.
　従って、防舷材構造体１３の防舷材本体４１が基板５３の一部によって固定されるため、防舷材構造体１３のガイド２１ａ及び２１ｂへの設置が容易となる。 Therefore, since the fender main body 41 of the fender structure 13 is fixed by a part of the substrate 53, the installation of the fender structure 13 on the guides 21a and 21b is facilitated.
　又、防舷材構造体１３の防舷材本体４１の支衝部４７ａ及び４７ｂを介して基板５３に取り付けられる受衝部４３は、図１４で示した平面視略台形形状以外であっても良く、例えば円錐台形状等のように様々な形状に適用できるため、防舷材構造体１３のバリエーションが増加する。 Further, even if the impact receiving portion 43 attached to the substrate 53 via the supporting portions 47a and 47b of the fender main body 41 of the fender structure 13 has a shape other than the generally trapezoidal shape in plan view shown in FIG. For example, since it can be applied to various shapes such as a truncated cone shape, the variation of the fender structure 13 is increased.
　以上のように、この実施の形態による防舷材の交換方法に関連する防舷材構造体１３は構成されているが、防舷材の交換方法は以下のような工程となる。 As described above, although the fender structure 13 related to the fender replacement method according to this embodiment is configured, the fender replacement method is the following steps.
　図１及び図１７から図１９を再度参照して、この実施の形態の防舷材本体４１ｂ及び４１ｃは、支衝部４７ａ及び４７ｂを有しない点や基板５３への取り付け方において第２の実施の形態のものとは相違するものの、基板５３の支衝部４７ａ及び４７ｂ側の面の上部には、金属製の丸棒等をコの字形状に折り曲げる等して形成した、防舷材本体４１を吊るすための一対の連結部５６ａ及び５６ｂが、横並びで取り付けられている。 Referring again to FIGS. 1 and 17 to 19, the fender main bodies 41b and 41c of this embodiment do not have the supporting portions 47a and 47b, and are attached to the substrate 53 in the second embodiment. Although it is different from the one of the above-mentioned embodiment, a fender main body is formed by bending a metal round bar or the like in a U-shape on the upper part of the surface on the support portions 47a and 47b side of the substrate 53 A pair of connectors 56a and 56b for hanging 41 are mounted side by side.
　そのため、この実施の形態による防舷材の交換方法は、防舷材本体４１ｂを取り出す第１工程と、防舷材本体４１ｃを取り付ける第２工程とのいずれにおいても、第２の実施の形態と同様となる。 Therefore, in the method of replacing the fender according to this embodiment, the second embodiment and the second step both in the first step of taking out the fender main body 41b and in the second step of attaching the fender main body 41c. It becomes the same.
　従って、連結部５６ａ及び５６ｂを介しての防舷材本体４１ｂ及び４１ｃの吊り上げ及び吊り下げ移動が可能となるため、図示しないワイヤー等の連結作業が容易となり、防舷材の交換時の作業効率が向上する。又、連結部５６ａ及び５６ｂは基板５３の支衝部４７ａ及び４７ｂ側の面の上部に取り付けられているため、潮位が高い状態でも防舷材の交換が容易となる。 Therefore, lifting and suspending movement of the fender main bodies 41b and 41c through the connecting portions 56a and 56b is possible, so that connection work of a wire or the like (not shown) becomes easy, and the work efficiency at the time of fender replacement Improve. Further, since the connection parts 56a and 56b are attached to the upper part of the surface on the side of the support parts 47a and 47b of the substrate 53, replacement of the fenders becomes easy even in a high tide state.
　図２０は、この発明の第４の実施の形態による防舷材の交換方法に関連する防舷材構造体を示す概略正面図であって、図２に対応した図であり、図２１は、図２０で示した防舷材構造体の概略平面図であり、図２２は、図２０で示した防舷材構造体の概略右側面図であって、図４に対応した図であり、図２３は、図２０で示したＸＸＩＩＩ－ＸＸＩＩＩラインから見た概略断面図であり、図２４は、図２０で示した防舷材構造体の防舷材本体を示す概略正面図であって、図１０に対応した図であり、図２５は、図２４で示したＸＸＶ－ＸＸＶラインから見た概略断面図であって、図２３に対応した図である。 FIG. 20 is a schematic front view showing a fender structure relating to a method of replacing fenders according to a fourth embodiment of the present invention, which corresponds to FIG. 2, and FIG. FIG. 22 is a schematic plan view of the fender structure shown in FIG. 20, and FIG. 22 is a schematic right side view of the fender structure shown in FIG. 20, corresponding to FIG. 23 is a schematic cross-sectional view seen from line XXIII-XXIII shown in FIG. 20, and FIG. 24 is a schematic front view showing a fender body of the fender structure shown in FIG. FIG. 25 is a diagram corresponding to FIG. 23, and FIG. 25 is a schematic cross-sectional view as seen from line XXV-XXV shown in FIG.
　尚、この第４の実施の形態による防舷材の交換方法に関連する防舷材構造体１４は、図２で示した第１の実施の形態による防舷材の交換方法に関連する防舷材構造体１１と基本的な構成は同一である。ここでは、その相違点を中心に説明する。 The fender structure 14 related to the fender replacement method according to the fourth embodiment is a fender relevant to the fender replacement method according to the first embodiment shown in FIG. The basic configuration is the same as that of the material structure 11. Here, the differences will be mainly described.
　これらの図を参照して、防舷材構造体１４のガイド２１ａ及び２１ｂは、図２で示した防舷材構造体１１のストッパー３１を有していない。図２４及び図２５を参照して、防舷材構造体１４の防舷材本体４１の支衝部４７ａ及び４７ｂは、その上端の一部に接続された位置固定部５０ａ及び５０ｂを有している。支衝部４７ａ及び４７ｂの内部の平板部４８ａ及び４８ｂの上端と、位置固定部５０ａ及び５０ｂの内部の平板部５１ａ及び５１ｂとは固定接続されている。位置固定部５０ａ及び５０ｂの下面は、ガイド２１ａ及び２１ｂの上端の一部に当接している。尚、位置固定部５０ａ及び５０ｂは、防舷材構造体１４の支衝部４７ａ及び４７ｂの上端以外の例えば中央位置等で接続されても良く、防舷材構造体１４の防舷材本体４１における接続位置を変えることで、防舷材本体４１の垂直方向における位置を調整できる。 Referring to these drawings, guides 21a and 21b of fender structure 14 do not have stopper 31 of fender structure 11 shown in FIG. Referring to FIGS. 24 and 25, the support portions 47a and 47b of the fender main body 41 of the fender structure 14 have position fixing portions 50a and 50b connected to a part of the upper end thereof. There is. The upper ends of the flat plate portions 48a and 48b inside the support portions 47a and 47b and the flat plate portions 51a and 51b inside the position fixing portions 50a and 50b are fixedly connected. The lower surfaces of the position fixing portions 50a and 50b are in contact with part of the upper ends of the guides 21a and 21b. The position fixing portions 50a and 50b may be connected at, for example, a central position other than the upper ends of the abutment portions 47a and 47b of the fender structure 14, and the fender body 41 of the fender structure 14 may be connected. The position of the fender main body 41 in the vertical direction can be adjusted by changing the connection position of the fender.
　従って、防舷材構造体１４の防舷材本体４１は、位置固定部５０ａ及び５０ｂによって下方への移動が阻止されるため、防舷材構造体１４を垂直方向において所望の位置に設置できる。 Therefore, since the fender body 41 of the fender structure 14 is prevented from moving downward by the position fixing portions 50a and 50b, the fender structure 14 can be installed at a desired position in the vertical direction.
　以上のように、この実施の形態による防舷材の交換方法に関連する防舷材構造体１４は構成されているが、防舷材の交換方法は以下のような工程となる。 As described above, although the fender structure 14 related to the fender replacement method according to this embodiment is configured, the fender replacement method is the following steps.
　尚、この実施の形態の防舷材の交換方法の基本的な工程は第１の実施の形態と同様であるため、ここでは相違点を中心に説明する。 The basic steps of the method of replacing fenders of this embodiment are the same as those of the first embodiment, and therefore, the differences will be mainly described here.
　図１、図２及び図２０から図２５を再度参照して、第１の実施の形態では、防舷材本体４１ｂを取り出す第１工程と、防舷材本体４１ｃを取り付ける第２工程とのいずれにおいても、防舷材本体４１ｂ及び４１ｃの下方への移動を阻止するために、ガイド２１ｃ及び２１ｄにストッパーが設けられていた。しかしながら、この実施の形態では、ストッパーを有しない代わりに防舷材本体４１の上端にはそれぞれ、位置固定部５０ａ及び５０ｂが取り付けられている。これにより、第１工程及び第２工程のいずれにおいても、防舷材本体４１に取り付けられた位置固定部５０ａ及び５０ｂの下面が、ガイド２１ａ及び２１ｂの上端の一部に当接し、防舷材本体４１はそれ以上、下方へは移動しないことになる。 Referring again to FIGS. 1, 2 and 20 to 25, in the first embodiment, any of the first step of taking out the fender main body 41 b and the second step of attaching the fender main body 41 c. Also in the above, in order to prevent the downward movement of the fender main bodies 41b and 41c, the guides 21c and 21d are provided with stoppers. However, in this embodiment, the position fixing portions 50a and 50b are attached to the upper end of the fender main body 41 instead of having no stopper. Thereby, in any of the first step and the second step, the lower surfaces of the position fixing portions 50a and 50b attached to the fender main body 41 abut on a part of the upper ends of the guides 21a and 21b, The main body 41 will not move further downward.
　従って、防舷材本体４１自体によって下方への移動が阻止されるため、防舷材本体４１の取付け状態の信頼性が向上する。 Therefore, the downward movement is blocked by the fender main body 41 itself, so the reliability of the attachment state of the fender main body 41 is improved.
　図２６は、この発明の第５の実施の形態による防舷材の交換方法に関連する防舷材構造体を示す概略正面図であって、図２に対応した図であり、図２７は、図２６で示した防舷材構造体の概略平面図であって、図２１に対応した図であり、図２８は、図２６で示したＸＸＶＩＩＩ－ＸＸＶＩＩＩラインから見た概略断面図であって、図２３に対応した図である。 26 is a schematic front view showing a fender structure relating to a method of replacing fenders according to a fifth embodiment of the present invention, which corresponds to FIG. 2, and FIG. FIG. 27 is a schematic plan view of the fender structure shown in FIG. 26, corresponding to FIG. 21, and FIG. 28 is a schematic cross-sectional view seen from line XXVIII-XXVIII shown in FIG. It is a figure corresponding to FIG.
　尚、この第５の実施の形態による防舷材の交換方法に関連する防舷材構造体１５は、図２で示した第１の実施の形態による防舷材の交換方法に関連する防舷材構造体１１と基本的な構成は同一である。ここでは、その相違点を中心に説明する。 The fender structure 15 related to the fender replacement method according to the fifth embodiment is a fender relevant to the fender replacement method according to the first embodiment shown in FIG. The basic configuration is the same as that of the material structure 11. Here, the differences will be mainly described.
　これらの図を参照して、防舷材構造体１５のガイド２１ａ及び２１ｂは、ガイド２１ａ及び２１ｂの上端に脱着自在に取り付けられる平板形状を有して、係合した防舷材本体４１の上方への移動を阻止する蓋部３５を備えている。蓋部３５は、ボルト３６ａ及び３６ｂを介して矢印の方向に、ガイド２１ａ及び２１ｂの連結部２６ａ及び２６ｆに取り付けられる。 Referring to these figures, guides 21a and 21b of fender structure 15 have a flat plate shape detachably attached to the upper ends of guides 21a and 21b, and are located above engaged fender body 41. A lid 35 is provided to prevent movement to the side. The lid 35 is attached to the connecting portions 26a and 26f of the guides 21a and 21b in the direction of the arrows via the bolts 36a and 36b.
　従って、係合した防舷材本体４１が上方に移動したときに、防舷材本体４１の上端の一部が蓋部３５の下面の一部に当接するため、防舷材構造体１５の防舷材本体４１が不用意にガイド２１ａ及び２１ｂから外れない。 Therefore, when the fender main body 41 engaged moves upward, a part of the upper end of the fender main body 41 abuts against a part of the lower surface of the lid portion 35. The main body 41 does not come off the guides 21a and 21b carelessly.
　又、蓋部３５は、蓋部３５を取り付ける際に、ガイド２１ａ及び２１ｂと係合した防舷材本体４１との隙間２２ａ及び２２ｂに挿入される、楔形状の突出部３７ａ及び３７ｂを備えている。このように構成した理由については後述する。 In addition, the lid portion 35 includes wedge-shaped projecting portions 37a and 37b which are inserted into the gaps 22a and 22b between the fender main body 41 engaged with the guides 21a and 21b when the lid portion 35 is attached. There is. The reason for this configuration will be described later.
　以上のように、この実施の形態による防舷材の交換方法に関連する防舷材構造体１５は構成されているが、防舷材の交換方法は以下のような工程となる。 As described above, although the fender structure 15 related to the fender replacement method according to this embodiment is configured, the fender replacement method is the following steps.
　尚、この実施の形態の防舷材の交換方法の基本的な工程は第１の実施の形態と同様であるため、ここでは相違点を中心に説明する。 The basic steps of the method of replacing fenders of this embodiment are the same as those of the first embodiment, and therefore, the differences will be mainly described here.
　図１及び図２６から図２８を再度参照して、防舷材本体４１を取り出す第１工程には、防舷材本体４１をガイド２１ａ及び２１ｂから取り出す前に、ボルト３６ａ及び３６ｂを図２６の二点鎖線の矢印で示す方向とは逆方向に取り外して蓋部３５を図２６の実線の矢印で示す方向とは逆方向に取り外す工程が含まれる。この時、蓋部３５に備えられ、ガイド２１ａ及び２１ｂと防舷材本体４１との隙間２２ａ及び２２ｂに挿入されていた突出部３７ａ及び３７ｂは蓋部３５と共に外れる。 Referring again to FIGS. 1 and 26 to 28, in the first step of removing the fender body 41, the bolts 36a and 36b are removed in FIG. 26 before the fender body 41 is removed from the guides 21a and 21b. The process of removing in the reverse direction to the direction shown by the arrow of a dashed-two dotted line and removing the lid part 35 in the reverse direction to the direction shown by the solid arrow of FIG. 26 is included. At this time, the protrusions 37 a and 37 b provided in the lid 35 and inserted in the gaps 22 a and 22 b between the guides 21 a and 21 b and the fender main body 41 are detached together with the lid 35.
　その後、第１の実施の形態と同様に防舷材本体４１を取り出し、新たな防舷材本体を取り付ける。 Thereafter, as in the first embodiment, the fender body 41 is taken out and a new fender body is attached.
　又、この防舷材本体４１を取り付ける第２工程には、防舷材本体４１をガイド２１ａ及び２１ｂに係合するように取り付けた後に、取り外された蓋部３５を図２６の実線の矢印で示す方向に再度取り付ける工程が含まれる。その際には、蓋部３５に備えられた突出部３７ａ及び３７ｂが、ガイド２１ａ及び２１ｂと新たな防舷材本体４１との隙間２２ａ及び２２ｂにそれぞれ挿入される。その後、ボルト３６ａ及び３６ｂを図２６の二点鎖線の矢印で示す方向に取り付けて固定する。 Further, in the second step of attaching the fender body 41, after attaching the fender body 41 to engage with the guides 21a and 21b, the lid 35 removed is indicated by the solid arrow in FIG. Reattaching in the direction shown is included. At this time, the protrusions 37a and 37b provided on the lid 35 are inserted into the gaps 22a and 22b between the guides 21a and 21b and the new fender main body 41, respectively. Thereafter, bolts 36a and 36b are attached and fixed in the direction indicated by the two-dot chain arrow in FIG.
　従って、蓋部３５が防舷材本体４１の上方向の移動を抑制するため、防舷材本体４１の設置状態の安定性が向上する。又、突出部３７ａ及び３７ｂが防舷材本体４１の前後方向の揺れを抑制するため、防舷材本体４１の設置状態の安定性が更に向上する。 Therefore, since the cover 35 suppresses the upward movement of the fender main body 41, the stability of the installation state of the fender main body 41 is improved. Moreover, since the protrusions 37a and 37b suppress the swing of the fender main body 41 in the front-rear direction, the stability of the installation state of the fender main body 41 is further improved.
　図２９は、この発明の第６の実施の形態による防舷材の交換方法に関連する防舷材構造体のガイドの設置状態を示す概略斜視図である。 FIG. 29 is a schematic perspective view showing the installation state of the guides of the fender structure relating to the method of replacing fenders according to the sixth embodiment of the present invention.
　図を参照して、この実施の形態による防舷材の交換方法に関連する防舷材構造体１６のガイド６１ａ及び６１ｂは、各々の断面がコの字形状に形成されている。岸壁７には、窪み部９が壁面８ａ側に開放されるように略凹形状に形成されている。ガイド６１ａ及び６１ｂの隙間６４ａ及び６４ｂは、互いに対向するように窪み部９の側壁に沿うように図示しないボルト等によって取り付けられている。その際、ガイド６１ａ及び６１ｂの各々の外面６２ａ及び６２ｂは、岸壁７の壁面８ａに整列するように、又、ガイド６１ａ及び６１ｂの内面６３ａ及び６３ｂは、岸壁７（窪み部９）の壁面８ｂと整列するように取り付けられる。 Referring to the drawing, guides 61a and 61b of fender structure 16 related to the fender replacement method according to this embodiment are each formed in a U-shaped cross section. The quay 7 is formed in a substantially concave shape so that the depression 9 is opened to the wall surface 8 a side. The gaps 64a and 64b of the guides 61a and 61b are attached by bolts or the like (not shown) along the side wall of the recess 9 so as to face each other. At that time, the outer surfaces 62a and 62b of the guides 61a and 61b are aligned with the wall surface 8a of the wharf 7, and the inner surfaces 63a and 63b of the guides 61a and 61b are the wall surface 8b of the wharf 7 (recessed portion 9). Attached to align with.
　このように構成すると、窪み部９の壁面８ｂが図２で示す第１の実施の形態の固定基板２７に相当するものとなる。又、窪み部９の底面１０が図２で示す第１の実施の形態のストッパー３１に相当するものとなる。 When configured in this manner, the wall surface 8b of the recess 9 corresponds to the fixed substrate 27 of the first embodiment shown in FIG. Further, the bottom surface 10 of the recess 9 corresponds to the stopper 31 of the first embodiment shown in FIG.
　図３０は、この発明の第６の実施の形態による防舷材の交換方法に関連する防舷材構造体を示す概略正面図であって、図２に対応した図であり、図３１は、図３０で示した防舷材構造体の概略平面図である。 FIG. 30 is a schematic front view showing a fender structure relating to the method of replacing fenders according to the sixth embodiment of the present invention, which corresponds to FIG. 2, and FIG. FIG. 31 is a schematic plan view of the fender structure shown in FIG. 30.
　尚、この第６の実施の形態による防舷材の交換方法に関連する防舷材構造体１６は、図２で示した第１の実施の形態による防舷材の交換方法に関連する防舷材構造体１１と基本的な構成は同一である。ここでは、その相違点を中心に説明する。 The fender structure 16 related to the fender replacement method according to the sixth embodiment is a fender related to the fender replacement method according to the first embodiment shown in FIG. The basic configuration is the same as that of the material structure 11. Here, the differences will be mainly described.
　これらの図を参照して、防舷材構造体１６の使用に際しては、第１の実施の形態と同様の構成を有する防舷材本体４１を、第１の実施の形態と同様に、ガイド６１ａ及び６１ｂの上方から、図３０の矢印が示す方向に差し込むようにして取り付ける。 With reference to these drawings, when using the fender structure 16, the fender body 41 having the same configuration as that of the first embodiment is set to the guide 61a in the same manner as the first embodiment. And 61b so as to be inserted in the direction indicated by the arrow in FIG.
　すると、ガイド６１ａ及び６１ｂとによって形成される隙間６４ａ及び６４ｂに防舷材本体４１の支衝部４７ａ及び４７ｂの一部がそれぞれ挿入される状態となる。又、窪み部９の底面１０により、防舷材本体４１の下方への移動が阻止される。 Then, parts of the support portions 47a and 47b of the fender main body 41 are respectively inserted into the gaps 64a and 64b formed by the guides 61a and 61b. Further, the bottom surface 10 of the recess 9 prevents the downward movement of the fender main body 41.
　以上のように、この実施の形態による防舷材の交換方法に関連する防舷材構造体１６は構成されているが、防舷材の交換方法は第１の実施の形態によるものと同様の工程となるため、ここでは説明を省略する。 As described above, although the fender structure 16 related to the fender replacement method according to this embodiment is configured, the fender replacement method is the same as that according to the first embodiment. Since this is a process, the description is omitted here.
　図３２は、この発明の第６の実施の形態による防舷材の交換方法に関連する防舷材構造体のガイドと第１の実施の形態によるガイドとを並設した状態を示す図である。 FIG. 32 is a view showing a state in which the guide of the fender structure and the guide according to the first embodiment related to the method of replacing fenders according to the sixth embodiment of the present invention are juxtaposed .
　第１の実施の形態によるガイド２１ａ及び２１ｂは、岸壁７の壁面８ａに窪み部等を設けることなく設置されている。そのため、岸壁７からガイド２１ａ及び２１ｂまでの第３の距離Ｌ３の分、岸壁７から突出している。一方、この実施の形態によるガイド６１ａ及び６１ｂは、上述したように、ガイド６１ａ及び６１ｂの各々の外面６２ａ及び６２ｂが、岸壁７の壁面８ａに整列するように設置されている。そのため、ガイド６１ａ及び６１ｂは、壁面８ａから突出しない。 The guides 21a and 21b according to the first embodiment are installed on the wall surface 8a of the quay 7 without providing a depression or the like. Therefore, minute third distance L 3 from the quay 7 to guide 21a and 21b, protrude from the quay 7. On the other hand, the guides 61a and 61b according to this embodiment are installed such that the outer surfaces 62a and 62b of the guides 61a and 61b are aligned with the wall surface 8a of the quay 7, as described above. Therefore, the guides 61a and 61b do not protrude from the wall surface 8a.
　従って、防舷材本体を外していた場合でも、図示しない船舶や水上の浮遊物等がガイド６１ａ及び６１ｂに接触しにくくなるため、接触の衝撃によるガイド６１ａ及び６１ｂの変形を抑制できる。 Therefore, even when the fender main body is removed, it is difficult for ships not shown and floating objects on water to contact the guides 61a and 61b, so that deformation of the guides 61a and 61b due to the impact of contact can be suppressed.
　又、断面コの字形状のガイド６１ａ及び６１ｂのみが、岸壁７の窪み部９に直接取り付けられることで、例えば、図２から図４で示す第１の実施の形態によるガイド２１ａ及び２１ｂのように、固定基板２７と保持部２３ａ及び２３ｂの各々と支持部２５ａ及び２５ｂの各々とを固定接続する連結部２６ａ～２６ｊに相当するものは設けられていない。そのため、ガイド６１ａ及び６１ｂを構成する部材が他の実施の形態の物に比べて少なくて済み、軽量化につながると共にコスト的に有利になる。 Further, only the guides 61a and 61b having a U-shaped cross section are directly attached to the depressions 9 of the quay wall 7, as in the guides 21a and 21b according to the first embodiment shown in FIGS. 2 to 4, for example. In addition, there is not provided one corresponding to the connecting portions 26a to 26j for fixedly connecting the fixed substrate 27, the holding portions 23a and 23b, and the supporting portions 25a and 25b. Therefore, the members constituting the guides 61a and 61b can be reduced in number as compared with those of the other embodiments, leading to weight reduction and cost advantages.
　図３３は、この発明の第７の実施の形態による防舷材の交換方法に関連する防舷材構造体のタラップ本体を示す概略正面図であって、図１０に対応した図であり、図３４は、この発明の第７の実施の形態による防舷材の交換方法に関連する防舷材構造体に相当するタラップ構造体を示す概略正面図であって、図２に対応した図である。 FIG. 33 is a schematic front view showing the flap body of the fender structure relating to the method of replacing fenders according to the seventh embodiment of the present invention, corresponding to FIG. 34 is a schematic front view showing a flap structure corresponding to the fender structure related to the method of replacing fenders according to the seventh embodiment of the present invention, which corresponds to FIG. .
　これらの図を参照して、この実施の形態による防舷材構造体１７（タラップ構造体６５）は、第１の実施の形態による防舷材本体４１をタラップ本体６６に置き換えたものである。ここでは相違点を中心に説明する。 With reference to these drawings, a fender structure 17 (a flap structure 65) according to this embodiment is obtained by replacing the fender body 41 according to the first embodiment with a wrap body 66. Here, differences will be mainly described.
　タラップ本体６６は、梯子部６７と基板５３とからなり、梯子部６７は補強用のチェーン等を埋め込んだゴム材料等からなり、一対の対向する側柱部６８ａ及び６８ｂと、側柱部６８ａ及び６８ｂの各々に対して垂直方向に横段部６９ａ～６９ｃが溶接等により接続されている。このように組み合わされた梯子部６７は、基板５３に一体的に固定されている。この固定の際は、第２の実施の形態のように、ナットと螺合したスタッドボルトを介して固定しても良いし、第３の実施の形態のように、接着剤等で固定しても良い。 The main body 66 is composed of a forceps portion 67 and a substrate 53. The forceps portion 67 is made of a rubber material or the like in which a reinforcing chain or the like is embedded, and includes a pair of opposing side pillars 68a and 68b, a side pillar 68a and Horizontal step portions 69a to 69c are connected by welding or the like in the direction perpendicular to each of the portions 68b. The forceps portion 67 combined in this manner is integrally fixed to the substrate 53. In the case of this fixing, as in the second embodiment, it may be fixed via a stud bolt screwed with a nut, or as in the third embodiment, it is fixed by an adhesive or the like. Also good.
　以上のように、この実施の形態による防舷材の交換方法に関連する防舷材構造体１７（タラップ構造体６５）は構成されているが、防舷材の交換方法は以下のような工程となる。 As described above, although the fender structure 17 (the tarlap structure 65) related to the fender replacement method according to this embodiment is configured, the fender replacement method is the following steps. It becomes.
　尚、この実施の形態の防舷材の交換方法の基本的な工程は第１の実施の形態と同様であるため、ここでは相違点を中心に説明する。 The basic steps of the method of replacing fenders of this embodiment are the same as those of the first embodiment, and therefore, the differences will be mainly described here.
　図１、図３３及び図３４を再度参照して、この実施の形態では、防舷材本体４１ｂを防舷材本体４１ｃではなく、タラップ本体６６に入れ替えるものである。 Referring again to FIGS. 1, 33 and 34, in this embodiment, the fender main body 41b is replaced with the tarp main body 66 instead of the fender main body 41c.
　そこで、係合した防舷材本体を取り出す第１工程は、第１の実施の形態と同様である。 Then, the 1st process of taking out the engaged fender body is the same as that of a 1st embodiment.
　次に、新たな防舷材本体に相当するタラップ本体６６を取り付ける第２工程においては、タラップ本体６６の横段部６９ａ～６９ｃに図示しないクレーン等のワイヤーを取り付ける。それをクレーン等で吊り下げ移動し、ガイドの上方から図３４の矢印が示す方向にタラップ本体６６を差し込むようにして取り付ける。 Next, in the second step of attaching the tarp main body 66 corresponding to the new fender main body, a wire such as a crane (not shown) is attached to the lateral step portions 69a to 69c of the main body 66. It is suspended and moved by a crane or the like, and the tarp body 66 is inserted and attached from above the guide in the direction indicated by the arrow in FIG.
　従って、状況に応じて防舷材本体４１ｂとタラップ本体６６とを入れ替えることができるため、岸壁の使用態様が拡大する。 Therefore, since the fender main body 41b and the tarp main body 66 can be switched depending on the situation, the usage mode of the wharf is expanded.
