【考案の詳細な説明】
この考案は係船岸壁、とくに荒天時にも船舶を係留する
ことができる係船岸壁の改良に関するものである。[Detailed Description of the Invention] This invention relates to the improvement of mooring berths, especially mooring berths that can moor ships even in stormy weather.
従来のこの種の岸壁は、一般に、許容変位量が20cm
程度の防舷材を複数配設することにより構成されている
ため、台風その他の荒天時において、防舷材の必要変位
量が50〜100cmにも達する場合には、船舶または
岸壁が破損するおそれがあった。Conventional quay walls of this type generally have an allowable displacement of 20 cm.
Because it is constructed by arranging multiple fenders of approximately 100 to 100 cm, if the required displacement of the fenders reaches 50 to 100 cm during a typhoon or other stormy weather, there is a risk of damage to the ship or quay. was there.
そこで、荒天時には船舶を港外へ退去させることによっ
て、それらの破損を防ぐことが一般的であったが、全て
の船舶の港外退去に際しては多くの時間と燃料が必要で
あり、また船舶隻数の増加した近年にあっては港外の停
泊スペースの確保が困難であるなどの問題があった。Therefore, it was common practice to prevent such damage by removing ships from the port during stormy weather, but it takes a lot of time and fuel to remove all ships from the port, and the number of ships increases. In recent years, as the number of ships has increased, there have been problems such as difficulty in securing berthing space outside the port.

マチックフェンダ−によって、大きな接舷エネルギーの
大部分を十分有効に吸収することができる。On the other hand, as disclosed in Japanese Patent Publication No. 49-25718, there is a constantly inflatable type that has a sufficient range of movement to climb up the berthing wall and land on the slab in synchronization with the movement of the berthed vessel. A fender device has been proposed in which a pneumatic fender and a solid fender that cushions the impact of the ship after the pneumatic fender rides on the slab are provided on the berthing wall. According to the device, most of the large berth energy can be sufficiently and effectively absorbed by the pneumatic fender during the primary berthing of a ship.

を設けない場合と全く同様の状態となり、船舶および岸
壁を有効に保護することができない問題があった。However, the pneumatic fender in this conventional technology runs aground on the slab in synchronization with the rising motion of the ship against the quay, and cannot contribute to energy absorption thereafter, so it is particularly difficult to use once the ship is parked. If the fender is repeatedly hit by the quay due to waves or wind during rough weather, pneumatic fenders should be installed.
The situation would be exactly the same as if no protection was provided, and there was a problem in that ships and quays could not be effectively protected.
この考案は、従来技術のかかる問題を有利に解決するも
のであり、船舶の一次接舷時はもちろん、その係留状態
での岸壁への衝突に対しても舷側および岸壁を確実に保
護することができる係船岸壁を提供するものである。This invention advantageously solves the problems of the prior art, and makes it possible to reliably protect the side and quay wall not only when the ship comes alongside, but also against collisions with the quay wall while the ship is moored. The purpose is to provide a mooring quay where ships can be moored.

気式防舷材の膨張時における移動を拘束してなる。The mooring wharf of this invention has a pneumatic fender whose protrusion height can be changed by supplying and discharging air between multiple fenders with low protruding heights. The pneumatic fender consists of at least a cylindrical body with both end faces closed, and protruding pieces that are integral with the cylindrical body, protrude to both sides of the cylindrical body, and extend in the axial direction. The protruding piece is fixed directly or indirectly to the side wall surface to restrain movement when the pneumatic fender is inflated.

ることになる。At this mooring quay, during normal times, air is removed from the pneumatic fenders and the energy of coming alongside is absorbed only by multiple fenders with low protruding heights, but in stormy weather, pneumatic fenders are required. By inflating to a protruding height of 50 to 100 cm depending on the ship's height, the pneumatic fender restrains the ship in a predetermined position, not only the primary energy of coming alongside the ship, but also the energy of collision with the quay after mooring. Sufficient absorption at all times provides reliable protection of the sides and quays.
以下にこの考案を図面に基いて説明する。This idea will be explained below based on the drawings.

2 is a wall surface, 2 is a plurality of fenders with a low protruding height that are fixed to this wall surface at predetermined intervals and used in normal times,
3 indicates a pneumatic fender.
この例の空気式防舷材8は、防舷材2,2間の所要位置
で、チェーン4およびアンカー5を介して壁面に間接的
に取り付けられる。The pneumatic fender 8 in this example is indirectly attached to the wall surface via the chain 4 and anchor 5 at a predetermined position between the fenders 2 .
ここで防舷材2は従来既知の防舷材で足り、たとえば、

とができる。Here, the fender 2 may be a conventionally known fender, for example,
As shown in FIG. 2, flanges 2b may be protruded from both sides of a fender main body 2a whose end surface is substantially V-shaped, and bolt holes may be provided in each of these flanges 2b.

通することにより壁面1に取り付けられる。The illustrated pneumatic fender 3 has a cylindrical main body 3a with both end faces closed, and around the cylindrical main body 3a, extends in the axial direction of the cylindrical main body 3a and extends across the end face in the diametrical direction. Flange 3b as a continuous protruding piece
It is attached to the wall surface 1 by inserting a plurality of chains 4 through the flange 3b.

和されることになる。Here, these chains 4 connect the flanges 3b to the wall surface on both sides of the cylindrical main body 3a, and the chains have a length that can effectively restrain the movement of the fender 3 when it expands. Therefore, when the fender 3 is expanded, it can always sufficiently absorb the energy of coming alongside at a predetermined position, and the flange 3b when coming alongside
Stress concentration on the chain 4 is sufficiently alleviated by the plurality of chains 4.
なお、図示はしないが、この空気式防舷材3が空気吸排
日を有することはもちろんである。Although not shown, it goes without saying that this pneumatic fender 3 has an air intake and exhaust date.
このように構成した係船岸壁において、波風の緩やかな
平常時には、空気式防舷材3からの抜気を行い(第3図
a参照)、防舷材2のみによって接舷荷重を支持する。In the mooring quay constructed in this way, during normal times when waves and winds are gentle, air is removed from the pneumatic fender 3 (see Fig. 3a), and the berth load is supported only by the fender 2.

を常に十分に緩和吸収する。On the other hand, during stormy weather, the pneumatic fender 3 is inflated (see Figure 3), and under the large permissible displacement of the fender 3, the ship is able to reach the quay not only when coming alongside but also after mooring. Even in the event of a collision, the berthing energy is always sufficiently mitigated and absorbed without damaging the ship or quay.
従って、船舶は荒天時にも港外へ退去する必要は全くな
い。Therefore, there is no need for ships to leave the port even during stormy weather.

ースの問題は有利に解決される。Therefore, according to this invention, the pneumatic fender always reliably absorbs energy at a predetermined position against the movement of the ship during stormy weather, so there is no need for the ship to leave the port during stormy weather, and there is no need to leave the port in the event of stormy weather. The problems of fuel wastage and off-harbour berth space are advantageously solved.
