Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting portion of a floating structure, particularly a floating pier, and particularly relates to a connecting portion that can reduce rocking of the floating structure.

Floating structures, such as floating piers and aquaculture rafts, which float on the surface of the water and are tethered to rock walls or the bottom of the water, are designed to follow vertical or horizontal changes in the water surface caused by waves or tides. It has become.

This floating structure basically consists of an upper deck and a lower float.

Further, this floating structure itself may be constructed by connecting a plurality of unit floating bodies, or may be constructed by connecting a plurality of floating structures.

The coupling device for making this connection is always a problem in relation to the ability to follow changes in the water surface, and various proposals have been made in the past.

A normal floating pier is shown in Figure 1 (top view) and Figure 2 (side view).
It has the structure shown in .

That is, a unit floating body 3.4 having a deck surface 1 and a float 2
．． 5 are connected by a plurality of connectors 6 to form a floating pier, one end of which is anchored to a rock wall 7 by a connector 8, floating above the water surface 9.

Chains, steel, elastic bodies, or other materials may be used as the connector 6, but a pin joint using a horizontal pin is considered most suitable in terms of stability in the horizontal direction.

Moreover, the connector 8 that connects the rock wall 7 and the floating pier is considered to be most preferably a rail joint, considering changes in the water surface due to the ebb and flow of the tide.

However, even floating piers using such connectors still lack sufficient stability.

That is, for example, when a person walks on this floating pier, the position of the center of gravity of the unit floating body changes depending on the position, and the unit floating body swings vertically or horizontally.

If a person walks from the rock wall to the tip of the floating pier as shown in Figures 1 and 2, the unit floating body 5.4 will experience pitching (pitching), and the unit floating body 3 will experience rolling movement (rolling). ) occurs.

These tremors not only make people feel extremely anxious, but also
Particularly in the case of side-to-side shaking, there is a risk that people or objects may actually be thrown into the water.

This is true not only when the connector 6 is a pin joint, but also when other movable coupling methods are used.

On the other hand, in order to eliminate this instability, it is conceivable to use a fixed connector.

However, although a floating pier using fixed connectors can be used on a calm water surface, on a water surface with strong waves, there is a risk of breaking the connector or damaging the floating pier.

In particular, even if the surface of the water is normally calm, it is often subject to destructive strength if it encounters a storm or typhoon.

Therefore, problems arise whether the unit floating bodies are connected in a swingable manner or in a non-swiveling manner, and no effective solution has hitherto been obtained.

Of course, this problem does not only occur with floating piers, but also with aquaculture rafts and other floating structures.

The present inventor conducted various research studies to solve the above problems regarding the connection of unit floating bodies on a floating pier.

As a result, during normal use, unit floating bodies are fixedly connected,
In the event of an emergency, we devised a connector that can be made movable as needed.

Once the connector is movable, it can be fixed again with a few adjustments and can be easily reused.

That is, the present invention provides a floating structure formed by connecting a plurality of unit floating bodies, in which the connecting portion of the unit floating bodies includes a main pin joint that connects the unit floating bodies in a swingable manner, and a main pin joint that has a breaking strength higher than that of the main pin joint. This floating structure is composed of a secondary pin joint with a small diameter, and the main and secondary pin joints are arranged so that forward swinging is suppressed by the secondary pin joint.

According to the present invention, a stable floating body can be obtained, and in the event of an emergency, damage or breaking strength of the floating structure can be effectively prevented.

FIG. 3 (front view) and FIG. 4 (side view) show an example of the connecting portion in the present invention.

Connecting pieces 10, 11.12 and two horizontal pins 13.14
The connecting member, which is a pin joint constructed by the above, suppresses the swinging of the units 15 and 16.

If excessive force is applied to this connection due to large shaking, etc., the thinner secondary pin 14 will be destroyed, and the main pin 13 will be destroyed.
This allows the connecting portion to swing.

In FIG. 4, the direction of the straight line connecting the main pin and the sub-bin is vertical, but it may be horizontal or may be any other direction.

The distinction between main pins and sub-pins is relative, and the sub-pin is the one that has lower strength against breakage, or the one that is more likely to be subjected to excessive force and is therefore more likely to break.

Alternatively, even if the pins are exactly the same, if one of them breaks, the other becomes difficult to break, so it may not be possible to distinguish them in particular.

The connecting portion of the present invention can be applied not only to the above-described one but also to various other applications.

For example, as shown in Figure 5, there are two sets of connecting pieces, one of which is a sub-connector, as shown in Figure 6, one of the connectors is a chain, and as shown in Figure 7. In addition, a chain is used for the main and sub-fixed connectors.

The one shown in FIG. 5 performs the same operation as the connector shown in FIG. 4, but because the distance between the main and sub-connectors can be increased, the sub-connectors can be easily destroyed.

In Figure 6, rocking occurs in the direction in which the connecting part lifts up, but if the breaking strength occurs at the pin joint, the unit body can swing not only vertically but also horizontally. The risk of damage to the unit is further reduced.

Of course, the chain can also be made easier to break.

In Fig. 7, even if one of the pin joints breaks, the unit will swing in the same way as in Fig. 6 and can be used as is, and if excessive force is applied, the pin joint or chain will break. Double safety can be ensured.

All of the above targets the case where the unit floating body swings in the vertical direction, but in the same way, when the unit floating body swings in the horizontal direction on the water surface, the direction of the pin should be vertical or other methods should be used. I can do it.

In addition, the present invention can use various types of connectors that have structures that can be made movable by partially breaking or disassembling them.

In addition to the above-mentioned pin joints and chains, the connecting device can also be an elastic body such as a rubber rod or plate, steel such as a rope, or other connecting devices, or multiple types of these can be used. Can be used in combination.

In addition, although the case where the sub-connector is destroyed due to the breakage of the pin or the breakage of the chain has been described above, it is not limited to this, and it is also possible to use a method in which the function of the sub-connector is lost through disassembly, such as a structure in which the pin comes off.

Once destroyed or disassembled, the sub-connection can be reconfigured with a few adjustments.

For example, by attaching a broken pin, it can be reused.

Therefore, the loss is the lowest compared to damage or breaking strength of the entire connector or the floating pier body, and the reuse cost and time loss until reuse are also small.

The connectors in the present invention are used for all or part of the connectors necessary to construct a floating pier.

For example, in the floating jetty shown in FIGS. 1 and 2, the biggest problem is the rolling of the unit floating bodies 3, so the connector of the present invention is installed at the part connecting the unit floating bodies 3 and 4. Use one or more of the following.

Of course, if necessary, it can also be used for the connection between the unit floating bodies 4 and 5.

Although the present invention has been described above using a floating pier as an example, the floating structure of the present invention can be used not only for a floating pier but also for a connector for constructing a structure floating on the water surface.

Floating structures other than floating piers include, for example, after aquaculture, rafts such as fishing and fishing rafts, artificial floating islands, and floating bridges.

These often consist of a float made of FRP or other synthetic resin, iron or other metal, or other material, and a deck made of synthetic resin, wood, metal, or other material.

In particular, it is preferable to use FRP floats due to their corrosion resistance and light weight.
