DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pontoon mooring method.

[0002]

2. Description of the Related Art Conventionally, pontoons have emphasized the inertia of trying to stop at the position, require a pontoon made of concrete as heavy as possible, and a chain sinker and other members mooring the pontoon are large objects corresponding thereto. It became. In addition, importance was placed on rigidity so as not to lose against external force.

[0003]

However, large pontoons, especially those made of prestressed concrete, guarantee the quality of the pontoons and deal with various restrictions that occur due to the large size, such as handling during transportation and launching and maintenance of receiving sites. Was needed. Also, once a pontoon was once installed, it was natural that it would not be moved again. Further, a structure that emphasizes rigidity has a weak point that it is extremely brittle when an unexpected external force is applied.

The present invention has been conceived in order to eliminate the above-mentioned drawbacks, and a pontoon having a desired size can be formed by combining block-shaped relatively small pontoons and mooring the pillar-shaped floating body. It is another object of the present invention to provide a method of mooring a pontoon capable of dispersing and absorbing a complexly acting force by flexibly shaking the entire upper structure moored to a sinker.

[0005]

According to a method of mooring a pontoon according to the present invention, weights are arranged in a grid pattern on the bottom of the water, and the weights are respectively floated in water, and a plurality of weights are provided in a columnar shape, which will be described later. Mooring a rod-shaped floating body arranged to surround the floating body, in the rod-shaped floating body, a column-shaped floating body with a suspended weight,
Each of the weights is held at a ratio of one to each, and the column-shaped floating bodies are connected by a plurality of chains in a grid pattern and arranged. The pontoon is arranged and connected by adjacent persons, and the connected corners are connected to the columnar floating bodies, respectively.

Further, according to the pontoon mooring method of the present invention, a sediment is provided linearly at the bottom of the water, and each of the sediments is made to float in the water so that a plurality of the sediments surround a columnar floating body described later. The placed bar-shaped floating body is moored, and in the rod-shaped floating body, a columnar floating body having a suspended weight is held at a ratio of one to each of the settling weights, and the columnar floating body is linear. A plurality of chains are connected to each other, and the block-shaped pontoons are arranged in a line at a ratio of two to the columnar flotation bodies, and the pontoons are connected to each other by adjacent persons. It is characterized by being connected to the floating body respectively.

[0007]

In the pontoon mooring method having the above structure,
When an external force is applied due to the influence of waves or water currents, the entire pontoon, columnar floating body, rod-like floating body, etc., which is the upper structure, flexes and absorbs the external force and is connected by a chain. You can keep together without doing it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a pontoon mooring method according to the present invention will be described below with reference to the drawings.

FIG. 1 is a view showing a first embodiment, in which four rod-shaped floating bodies 2, 2,... Are connected to a sinking weight 1 submerged in the water bottom, and rod-shaped floating bodies 2, 2,. The column-shaped floating body 3 is suspended at the center by the weight 4 and is held by being bound by the locking means 14, 14,. Such columnar floating bodies are arranged in a grid pattern. The adjacent columnar levitating body 3 is connected by two chains 5,5. FIG. 2 is a top view of the first embodiment, in which columnar floating bodies 3, 3,... Are arranged in a grid pattern, and one block-shaped pontoon 6 is arranged in one square of the grid. And the columnar floating body 3. FIG. 1 shows a state in which the block-shaped pontoon 6 is connected to the upper part of the columnar floating body.

As shown in FIG. 2, the corners of the four block-shaped pontoons 6 are concentrated on one pillar-shaped floating body 3, and the corners are connected to the pillar-shaped floating body at the same time as the block-shaped floating body. The pontoons 6 are connected to each other by a connecting means of H steel of a key member and a shredded fitting groove of the pontoon described in Japanese Patent Application No. 3-255728.

The connection between the columnar floating body 3 and the block-shaped pontoon 6 is, as shown in FIG.
Surrounding members 8, 8 are placed above and below, with 7,
An iron plate is attached to the upper surface of the upper surrounding member 8 with bolts and fixed. Since the block-shaped pontoons 6 are connected to each other as described above, a large force is not generated at the connection portion with the columnar floating body 3 and deformation is small. Since a rubber tire is provided between the block-shaped pontoon 6 and the columnar floating body 3, a slight vertical displacement can be absorbed. The surrounding member 8 is made of rubber or synthetic resin and has elasticity, and works together with the rubber tires 7, 7,... To absorb a slight inclination of the columnar floating body 3 with respect to the block-shaped pontoon 6.

FIGS. 3 and 4 are a plan view and a side view of an example of the block-shaped pontoon 6 of the first embodiment. The corner is
It is cut in accordance with the size of the columnar floating body 3, and the shredded fitting grooves 9, 9,... Are formed.

FIG. 5 is a view showing a second embodiment, in which the columnar levitation bodies 3 are arranged linearly and the block-shaped pontoon 10 is formed.
Are arranged in a line. The connecting portion of the pontoon 10 is connected by a columnar floating body 3, and the columnar floating body 3 is fitted and moored in the middle of the pontoon 10. Adjacent block-shaped pontoons 10 are connected by a chain 11.

FIGS. 6 and 7 are a plan view and a side view of an example of the block-shaped pontoon 10 used in the second embodiment. Holes 12, 12, ... to which the columnar floating body 3 fits are open,
Further, the chain fixing members 13, 13,.

The method of holding the columnar floating body 3 in the second embodiment is the same as that of the first embodiment, and the method of connecting the block-shaped pontoon 10 to the columnar floating body 3 is also the same as that of the first embodiment. .

In both the first and second embodiments, the columnar floating body 3
Because the weight 4 is attached, it is stable, and is further surrounded by the rod-shaped floating bodies 2, 2,... And is held by the locking means 14, and is connected to the other column-shaped floating bodies and two chains. Because it is connected, it swings slightly but has a stable structure.

The block-shaped pontoons 6 or 10 are collectively connected, respectively, and integrally form a plane. Further, the material is such that the inner polystyrene foam is covered with a surrounding concrete wall, and may be glass fiber or the like.

The linear pontoon formed in the second embodiment can be used for a long and thin floating pier for mooring many small boats side by side at a yacht harbor or the like.

[0019]

According to the present invention, the columnar levitation body is surrounded by a plurality of rod-shaped levitation bodies moored to the sinker, held, arranged in a plurality, connected by a plurality of chains, and the block-shaped pontoon is combined with the columnar levitation body. And the upper structure other than the sinker is shaken as a whole, and the whole structure is connected flexibly, so it can disperse and absorb the complex acting force, and is stable and strong against external force. Can be formed. In addition, a pontoon of a desired size can be formed, and assembly and disassembly are easy. An extremely useful effect such as easy relocation is achieved.
