The present invention is a floating structure, such as a place for holding a ship in a port, or a place for loading and unloading cargo, that is, a floating structure (a floating structure) and a buffer installed in the pile (pile) disposed around it (a shock-absorber).

Conventionally, a catenary that is loosely moored by a chain or the like in a fishing port or harbor located in a sea area with a large tidal gap, such as a ship tie-up or loading dock, that is, a cargo unloading place. Mooring is common.

However, if the mooring is loosely carried out by a chain or the like, the initial spring constant is extremely low, so the fluctuation of the floating body is increased by wind pressure or wave force, and the spring constant suddenly changes when the motion reaches parallel. There is a problem that the shape is generated and the load or the person is subjected to a large negative acceleration to become an unstable state, the work efficiency is lowered and the risk of work increases, and there is also a problem that causes the collapse of the cargo.

There is also the problem of occupying vast waters for mooring and disrupting the navigation of ships.

Thus, in order to solve the above problems, as shown in FIG. 4, a structure in which a pile (2: a pile) such as a steel pipe is beaten and placed on the water level of the floating structure 1 is used to suppress movement. have.

There are two types of structures for controlling the movement of the floating structure, one of which forms a quadrilateral with a predetermined interval between the side surfaces of the floating structure 1 as shown in FIG. The supporter 3 is installed, the roller 4 is attached to each side of the supporter 3 so as to be rotatable, and used as a shock absorber, and the pile 2 is disposed in the supporter 3 in such a manner. Thus, the floating structure 1 is not in contact with the pile (2).

Another structure is a structure in which a fender 5 for a peripheral wall of a predetermined length is attached to an inner side of a pile 2 around the pile 2 so as to be a shock absorber and oppose the floating structure.

The shock absorber disposed between the pile and the floating structure needs to alleviate the impact load caused by the external force acting on the floating structure and to move the floating structure of the floating structure by the tide alone without resistance.

However, in the foregoing description, the former technique has a problem that it can be followed by the rotation of the roller in shanghai-dong caused only by tides, but the effect of mitigating impact load is hardly expected.

In addition, in the latter technique, the impact load can be alleviated. However, if the floating structure is moved by tidal tides while the floating structure is pushed to the fender, the fender wears and damages due to the frictional resistance. There is a problem in that the length of the car according to the car must be installed.

The present invention attaches a support at predetermined intervals around a side surface, and attaches at least one cushioning material with rollers to the support to form a floating structure, each of which is disposed around the floating structure by such a roller. The pile is supported with the intervening structure to stably install and cushion the floating structure.

According to the above structure, the floating structure is always supported in the horizontal direction because the rollers attached to the surrounding support are supported by the piles, and the impact generated by the wave force is also obtained. The load can be alleviated by the deformation of the cushioning material and the roller can be smoothly coped with the floating motion of the floating structure.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of a floating structure and pile, FIG. 2 is a plan view of a shock absorber according to the invention, FIG. 3 is a side view of such a shock absorber, and in the figure 6 is a circumference of the side of the floating structure 1. The support is attached to the predetermined intervals in the, in the illustrated embodiment is a rectangular frame.

7 is a cushioning material attached to each side of the said support body 6 with a bolt etc., It is made from elastic materials, such as rubber | gum, and the hollow part 7a is provided as needed. Moreover, the compression mechanism 8, such as a press bolt, is fitted in the predetermined | prescribed place of such the shock absorbing material 7, and the compression displacement is previously applied.

9 is a roller, which is rotatably attached to the shaft of the roller support 10 attached to the cushioning material 7 by bolts or the like. Such a roller 9 may have a structure in which a spring constant is increased as an alternative lamination of rubber and synthetic fibers or an alternative lamination of rubber and synthetic resin, in addition to a single structure such as rubber.

As described above, the rollers 9 are attached to the cushioning material 7 via the roller support 10 so as to be integrated with each other. As described above, the buffers are attached to each side of the support 6 or two sides facing each other with a bolt or the like. Configure

The piles 2 are respectively arranged in the shock absorbers of the respective support bodies 6 thus constructed, and the respective rollers 9 of the respective shock absorbers are connected to the outer periphery of each of the piles 2 in such an arrangement.

Thus, by separating the compression mechanism 8 previously fitted to the shock absorbing material 7, the initial compression displacement is restored, and the respective rollers 9 are pressed against the pile 2 by the repulsive force.

By virtue of the interaction of the respective rollers 9 of each support 6 attached to the surroundings, the floating structure 1 is installed in a stable state in the horizontal direction without touching the fixed pile 2. .

According to the above structure, the rotation of the roller 9 responds smoothly to the shank-dong of the floating structure 1 due to the intertidal difference, and the shock load generated by the external force can be alleviated by the deformation of the cushioning material. In addition, since the pile is held between the rollers, the pile is extremely stable in the horizontal direction.

In addition, although the pressurization bolt was illustrated as a compression mechanism for giving an initial displacement in the said structure beforehand, it is not necessarily limited to a pressurization bolt, Any structure may be sufficient as a means for compressing the cushioning material 7 beforehand, for example, a lip Or pins.

According to the present invention described in detail above, by attaching the support at a predetermined interval around the outside of the side, at least one cushioning material attached to the roller is attached to the support to form a floating structure, such rollers between the pile The floating structure can be stabilized in the horizontal direction by installing the floating structure so that the floating structure can be supported, and the impact load generated by the external force can be alleviated by the deformation of the cushioning material. The shanghaidong has an effect that can be smoothly handled by the rotation of the roller.
