Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a floating pier used for mooring small RDs (hereinafter referred to as ships) for boarding and disembarking people, storage, etc.

(B) Conventional technology A conventional floating pier is either a box-shaped pontoon in which the entire outer shell structure of a rectangular parallelepiped functions as a float, or a single floating pier, such as a floating pier with floating bodies attached to key points at the bottom of a pier with a rectangular plane. Or, a floating pier with a vertically connected configuration in which these structures are vertically connected to each other in a flexible structure using hinges, etc., or a floating jetty with a vertically connected structure for the purpose of improving convenience and capacity when connecting ships. It was a floating pier with a vertical structure in which a tangential floating pier orthogonal to the floating pier was connected by a hinge or the like to form an inlet by the floating pier.

In addition, conventional floating platforms are those that are intended for one floating platform to lower and lower one ship, or, like floating docks,
It existed as an independent entity, such as for the purpose of simply building ships.

(c) Problems to be solved by the invention When a conventional floating pier is used on the surface of the sea or a lake, it is subject to large fluctuations due to the influence of waves, and the floating pier with a connecting structure is also constructed by connecting flexible structures. , each of the floating QFs that make up the connected floating pier had the disadvantage that it swayed independently, causing trouble for people to walk or work. As mentioned above, many users who use floating piers to moor and store ships are That was difficult.

In addition, since the conventional floating pier only had the function of mooring a ship, when the ship was moored and stored, there was a drawback that the bottom of the ship was inevitably contaminated by marine organisms and the like.

In order to eliminate these drawbacks of the conventional floating pier, the present invention has developed a pontoon with an M-tank configuration that has an integral structure so that the entire structure is rigid, and also has a collective floating platform function, which is less shaken and more practical. This provides a floating pier with excellent performance.

(d) Means for Solving the Problems The floating pier of the present invention includes a center pontoon in which a plurality of floating bodies are connected by each pier so as to have a rigid structure, and a plurality of floating bodies arranged on both sides of the center pontoon. The floating body is composed of a side pontoon floating body and a side pontoon pier which is connected to the center pontoon so as to have a rigid structure, and the entire floating pier has a rigid structure.

In addition, this floating pier has a rigid structure in which the center pontoon and each of the coves formed by the side pontoons have a rigid structure. Therefore, the amount of deflection change between the center pontoon and each side pontoon that make up the floating pier is small. Therefore, even if a guide device for the floating and sinking movement of a floating boat is provided on each of the adjacent side pontoons that form an inlet, and used as a guide device for a single floating boat provided in the inlet, there will be no difference between the guide devices. In order to prevent the smooth floating and sinking movement of the floating platform from being disturbed by displacement or deformation of By pouring in water, the floating platform can be used as a collective floating platform to raise and lower a ship.

(e) Effect With the above configuration, the floating pier of the present invention, which has a rigid structure that does not use flexible joints, has less rocking caused by waves when used on the sea surface, lake surface, etc. By equipping it, a collective floating platform can be constructed.
