Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connecting device for floating bodies, particularly for constructing a floating structure for connecting floating bodies to each other and mooring a small boat such as a yacht. The present invention relates to a floating body coupling device suitable for various cases.

[Prior Art] This type of connecting device for floating bodies connects floating bodies floating on the water surface, and in relation to the present invention, it is described in Japanese Utility Model Publication No. 54-21348 and Japanese Utility Model Publication No. 57-23541. Mention may be made of the techniques described.

In the floating body coupling devices disclosed in both publications, when the floating bodies attempt to separate from each other, their movement range is restricted by chains or the like that are respectively latched at one end to both floating bodies. In addition, when floating bodies approach each other, elastic members such as fenders and shock absorbers fixed to opposing end faces of the floating bodies act directly or indirectly to prevent harm caused by collisions between the floating bodies. It is.

[Problems to be Solved by the Invention] However, the above-mentioned prior art lacks integration of the chain member that acts to separate the floating bodies from each other and the elastic member that acts to prevent the floating bodies from approaching each other, and the nuts and These parts had to be individually transported and managed together with the bolts and other mounting members, and there was a problem in that they were often bent during handling.

In addition, the work efficiency was poor because it was necessary to attach chain members to each large concrete floating body and to fix the elastic member to a predetermined portion of the opposing end face.

Furthermore, since separate elastic members were provided on each surface facing the floating bodies, when the floating bodies moved up and down at different tempos and moved irregularly, the elastic members could rub against each other, but this provided effective cushioning. Or they couldn't expect energy absorption.

As a result of repeated studies based on the above background, the present applicant found that all the problems could be solved by unitizing the floating body coupling device itself, and arrived at the present invention.

The purpose of the present invention is to make the connecting device itself into a unit so that it can be easily handled and to improve the connecting workability.In addition, the elastic member can efficiently absorb energy even when the floating bodies move irregularly. The object of the present invention is to provide a coupling device.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a floating body connecting device for connecting floating bodies floating on the water surface, including a pair of steel brackets arranged at a predetermined interval. and a rigid member that locks one end of each of the brackets to opposing surfaces of the brackets to connect the brackets so that they can be separated and separated within a predetermined range;
one of the brackets is coupled to a corresponding fixing part provided on an opposing surface of each floating body, with the rigid member located inside, and an elastic member compressably assembled between the brackets; It is characterized by

[Function] With this configuration, when adjacent floating bodies are spaced apart by H from each other due to irregular movement of waves, the rigid member works to regulate the maximum distance between them, and also when adjacent floating bodies are separated from each other by When the brackets approach each other or move up and down at different tempos, the elastic member installed between the brackets immediately compresses or compresses and deforms, efficiently absorbing energy and absorbing all kinds of patterns between floating bodies. Suppresses and alleviates the vibration of the

[Example] Embodiments of the present invention will be described below based on the drawings.

FIGS. 1A and 1B are a plan view and a side view schematically showing a floating structure constructed by applying the present invention.

The floating structure shown in the figure is constructed by sequentially connecting a plurality of floating bodies 1 to form a mooring shore 2. This mooring shore 2 is positioned by a mooring member 3 such as a chain, and the mooring shore 2 and the land shore 4 are positioned by a mooring member 3 such as a chain. It is equipped with a bridge 5 between the two.

The floating body 1 is formed in a factory or the like as a single concrete box-like item and transported to the facility site.In this case, a steel holding member 6 that becomes a fixed part as shown in FIG. 4 is attached at the factory or facility site. will be provided. The holding members 6 are provided at both ends 1M1a of the floating body 1 in the longitudinal direction, and on both sides of the upper part.
The holding part 6a is shaped like an abbreviation and has a pair of holes in its horizontal part, and the horizontal part of the holding part 6a is reinforced and held from below by a support plate 6b. .

The holding member 6 also includes a core shaft 7 that is disposed inside the floating body 1 along the longitudinal direction and protrudes from both ends 1a.
It can be installed using. A total of four pieces of wood are inserted into the shaft 7 on both sides of the lower part of the floating body l, and the shaft 7 protrudes through a bearing plate 8 disposed in the vertical direction of the end face 1a, and the protruding end 7a on which the threaded thread is formed is connected to a nut 9, etc. It is tightened by. When tightening the upper nut 9, the holding member 7 is aligned with the spacer and fixed to the floating body l side.

The above-described floating bodies 1 are lowered onto the ocean or water where they will be installed using a crane or the like, and are successively connected by the connecting device IO of the present invention.

As shown in FIGS. 2 to 3, the connecting device 10 is compressible between a pair of steel brackets 11, metal fittings 12 and 13 serving as rigid members that connect the brackets 11 to each other, and the brackets 11. It consists of an elastic member 14 that is attached to the sheath, and a plate-like cover 15 that is attached to the top of each bracket 11.

The bracket 11 is a block-shaped integrally molded product. This - side part has a notch 1 having a generally convex cross section that closes in the vertical direction.
1a, and a horizontal engagement groove 11b penetrating below -F is formed in the inner wall on the end side of the notch 11a, and a pair of through holes 11c are provided in parallel with the engagement groove 11b. .

In addition, on the other side, a disk-shaped support portion l protrudes from the end surface.
id, and the support part 11d! I! and the notch 11a are penetrated by a hole lie. The holes 11e are provided at two locations on a vertical line at a predetermined interval.

A metal fitting 12 is provided in the hole lie so as to protrude from the end surface side of the support portion 11d. The metal fitting 12 is shown in Fig. 2 (a).
As shown in (b), it is approximately U-shaped with threads formed on both ends, and both ends are connected to the corresponding hole li from the support part IId side.
It is assembled by inserting it into the hole e and protruding into the notch 11a, and screwing nuts 16 onto both ends.

When attaching this metal fitting 12 to the sheath, the metal fitting 13 is attached to the metal fitting 12.
can be hooked inside. The metal fitting 13 has a relatively long oval shape and is movably connected to the inside of the metal fitting 12.

Furthermore, when attaching the next metal fitting 12 of the pair of metal fittings 12, this is done with the metal fitting 12 and the metal fitting l:3 already fixed to the bracket 11 being inserted into the inside of the elastic member 14. Needless to say.

The elastic member 14 is a generally cylindrical rubber molded body whose diameter is slightly larger at the middle than at both ends. The length of the elastic member 14 is set to the length when the metal fittings 12 located on both sides of the metal fitting 13 move the most in the direction of separation, as shown in FIG. is compressed immediately.

Next, an example of operation for connecting floating bodies l using the connecting device 10 will be described.

First, the coupling device 10 is fixed to one side of the floating body 1. In this case, as shown in FIG.
After holding the bracket (11) on the horizontal part of the holding part (6a) while fitting the vertical part of the cover (15), the cover (15) is attached to the top of the bracket (11). The cover 15 is shown in Fig. 2 (a) and (b).
As shown in FIG.
is fixed by tightening with a nut 18 on the horizontal lower side of the holding part 6a. In addition, in FIG. 2, the cover 5 is fixed to only one side of each bracket 11.

Therefore, in this fixing structure of the holding member 6 and the bracket 11, the bracket 11 is temporarily fixed by simply fitting the vertical part of the holding part 6a into the engagement groove Jlb, and the engagement groove 11b is fixed to the holding part 6a. In addition to being held down by the cover 5 to prevent it from coming off from the vertical part of the holding part 6a, it is also tightened with bolts 17 and nuts 18 to the horizontal part of the holding part 6a, and the movement in the vertical and horizontal directions is reliably regulated, resulting in high strength. be combined.

Then, by connecting the other bracket 11 to the holding member 6 provided on another adjacent floating body 1 by a similar operation, the plurality of floating bodies 1 are successively connected and integrated with each other via the connecting device 10. be converted into

Note that the coupling device 10 is usually fixed to a predetermined floating body I at a factory or at a transportation site before each floating body 1 is floated on the sea surface or on the water surface, and when each floating body 1 is floating on the water surface, unattached brackets are connected to the floating body 1. Needless to say, the Il side is connected by the procedure described above.

5(a) to 5(c) show the operation of the coupling device 10, and will be explained below with reference to the same figures.

Figure (A) shows a situation where the floating bodies 1 approach each other from a substantially horizontal direction due to movement of waves or the like.

In this case, the elastic member 14 is compressed depending on the degree of approach, and the distance between the brackets 11 is narrowed. When both ends of the metal fittings 13 collide with the end faces of the supporting parts 11d of the corresponding brackets 11 through the inner space of each metal fitting 12, the floating bodies 1 are completely prevented from approaching each other. In the embodiment, the length of the elastic member 14 is designed to be about 331, and when it is compressed to 301, the metal fittings 13 come into contact with each support portion lid. The elastic member 14 absorbs the movement energy of each floating body 1 during the compression process, and efficiently suppresses and alleviates the rocking of the floating bodies 1 with respect to each other.

In addition, when adjacent floating bodies 1 are separated from each other by fi, the maximum separation amount is regulated by the metal fittings 12 and 13.

Figures (b) and (c) show that adjacent floating bodies 1 move up and down at different tempos due to irregular up-and-down movements of waves, etc.
This shows a state in which the floating bodies 1 move toward each other in a V-shape. In this case, the metal fittings 13 will freely move or tilt relative to each metal fitting 12, and in this process, the elastic member 14
absorbs the movement energy of each floating body 11 while being immediately compressed and deformed, and efficiently suppresses and alleviates the rocking of each floating body 1.

In particular, the present invention provides the elastic member 14 itself in a compressible manner between the brackets 11, so there is no need to worry about positioning relative to the conventional method of abutting two elastic members. Since the compression action is more instantaneously linked to any rocking motion between the floating bodies 1, the stability of the floating bodies 1 can be improved.

FIG. 6 shows the main parts of a floating body coupling device as a second embodiment of the present invention.

The coupling device 100 in the figure includes a pair of steel brackets) 110
, a rod 120 as a rigid member connecting the brackets 110, and both ends 120a, 120 of the rod 120.
A relatively small elastic body 130 provided at b, and an elastic member 140 compressably attached to the bracket) 110m.
It is roughly composed of.

Each bracket 110 is approximately U-shaped. A through hole 110 is provided on a vertical line in the U-shaped horizontal portion 110a.
b is provided, and a through hole 110c is provided approximately at the center of the U-shaped vertical portion. Further, holding pieces 111 are provided on the outer end surface of the vertical portion, and each holding piece 111 supports the elastic member 140. Although a cylindrical rubber molded body is used as the elastic member 140, it may be shaped like a piece or a tongue, for example. In this case, the structure of each holding piece 111 is changed so that a piece-like or tongue-like elastic member can be appropriately supported.

The rod 120 acts as a stopper when the opposing bracket 110 is about to leak beyond a predetermined range.Here, both ends of the rod 120 are arranged to protrude into the corresponding through hole 110c, and the elastic body 130 is An intervening nut 121 prevents removal. Elastic body 13
0 consists of a rubber molded body having a rod insertion hole in the center, and washers 1, 31, and 132 are integrally welded to both end faces.

The above connecting device 100 has, for example, each bracket 1.10
Assemble the elastic member 140 when arranging the spacers to face each other,
Further, by subsequently assembling the rod 1201 and the elastic body 130, the rod 1201 can be easily integrated. Then, as in the previous embodiment, the coupling device lOO is fixed to one side of the floating body 1 on land. As shown in the figure, the floating body 1 is provided with a holding member 60 that serves both as the above-mentioned holding member 6 and the bearing plate 8. The holding member 60 has a horizontal mounting portion 60a on the upper side,
60b, and is attached using a core shard 7.

Therefore, the horizontal mounting portions 60a and 60b have plaques.
The horizontal portion 110a of 110 is arranged to sandwich from the outside, and the headed connecting shaft 14 is inserted into the through hole tiOb of the horizontal portion 110a and the through holes provided in the horizontal mounting portions 60a and 60b.
0 through the through hole 1 of the lower horizontal portion 110a.
1) At the protruding end of the connecting shaft 140 protruding from 10b
4, the connecting device 100 is attached. In addition, in water, the other bracket 110 is attached to the holding member 60 provided on another adjacent floating body 1 by a similar operation, so that a plurality of ? The idle bodies are successively connected and integrated via the connecting device 100.

In the coupling device lOO of this second embodiment, when the floating bodies 1 move relatively close to each other, that is, when the brackets 11
When the distance between the two floating bodies 1 is narrowed, the elastic member 140 is immediately compressed, and the rocking of the floating bodies 1 is efficiently suppressed and alleviated.

Further, when adjacent floating bodies l are separated from each other, the maximum at distance is regulated by the rod 120 and the nut 121, but the elastic body 130 acts in the process of reaching this maximum distance. In other words, when the brackets 110 try to expand, the elastic body 130 is compressed,
By compressing the elastic body 130, the rocking of the floating bodies 1 with respect to each other is efficiently suppressed and alleviated. Furthermore, as shown in Figures 5 (B) and (C), due to the irregular downward movement of waves, adjacent floating bodies 1 move up and down at different tempos, and floating bodies 1 move toward each other in a V-shape. In the process of
0 and the elastic body 130 are both compressed or compressed and deformed, absorbing the movement energy of each floating body 1, suppressing and mitigating the oscillation of each floating body 1 with high efficiency, and greatly improving the stability of the floating bodies 1. be.

In the above, the floating body 1 is an example of an integrally molded concrete body, but the floating body 1 includes a plurality of floating boxes rigidly and completely fixed.

In this case, by using the shaft 7 as a connecting and fixing member for tightly connecting the floating boxes, it is possible to reduce the amount of materials used. Furthermore, although the connection devices 10 and 100 have been described for connecting the floating bodies 1 to each other in a straight line, the present invention is not limited to such a case. It may also be applied when connecting at right angles. As described above, the present invention can be modified in various ways within the scope of its gist.

[Effects of the Invention] As explained above, in the floating body coupling device according to the present invention, since the elastic member is compressably provided between the tonal brackets, adjacent floating bodies may not be connected to each other due to irregular movement of waves. When the floating bodies move up and down at different tempos, the elastic members are immediately compressed or compressively deformed in conjunction with the movement, efficiently absorbing energy, and suppressing and alleviating any rocking between the floating bodies.

In addition, the present invention has a pair of steel brackets, rigid members such as chains and rods, and nine elastic members that are integrally assembled into a unit, making it easier to handle in transportation and management. The number of parts fixed to the floating body can be reduced to improve reliability, and the workability is also good because the connection work on the water surface only requires connecting one bra and the identification part.
