ものである。[Detailed description of the invention] [Technical field of the invention] This invention relates to a connecting structure for floating fenders, and more specifically, the invention relates to the connection structure of floating fenders. This invention relates to an improvement in the connection structure of floating fenders that absorbs water, prevents damage to ships, and protects underwater structures.
近年、船舶航行量の多い海域に長大橋等が建設
され、これに伴つて、その橋脚部等の水中構造物
に船舶が誤つて衝突する危険が多くなつてきた。
In recent years, long bridges and the like have been constructed in sea areas where there is a large amount of ship traffic, and as a result, the risk of ships accidentally colliding with underwater structures such as bridge piers has increased.

衝突エネルギーを吸収して船舶の水中構造物への
衝突を防止し、水中構造物および船舶の損傷を最
小限に抑え得るようにしている。 Therefore, a connecting structure of floating fenders is installed around the underwater structure, and when a ship enters the underwater structure, this fender receives the ship, absorbs the collision energy of the ship, and prevents the ship from entering the water. This prevents collisions with structures and minimizes damage to underwater structures and ships.

る。 However, as shown in Figs. 1 and 2, the conventional connection structure F of this type of floating fender generally consists of multiple pieces having buoyancy, such as pneumatic fenders and foam fenders. The floating fenders 10 are connected to each other by a chainnet 40 to form an underwater structure G.
In order to prevent this from being washed away, it is moored to the underwater structure G using a mooring device A, and if a floating object such as a ship or driftwood collides with this underwater structure G. When the collision occurs, the collision energy is absorbed, preventing damage to the ship and protecting the underwater structure G.
ところが、上述したような構造の従来の浮遊式

もに空気式防舷材の場合には沈没する危険があ
る。 However, the conventional floating fender connection structure F having the structure described above has the following drawbacks. That is, (1) Since fluctuating external forces such as waves and tidal currents constantly act on the floating fender connection structure F, the floating fender 10 sways independently, resulting in a chain network consisting of chains, shackles, etc. 40 is worn out and deformed,
If the shaft falls off and the connection function is lost,
Contact and collision with metal fittings of the floating fender 10 will cause wear and tear on the main body, impairing the cushioning performance, and in the case of pneumatic fenders, there is a risk of sinking.
(2) また、損傷した浮遊式防舷材10の補修、交
