Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a structure for connecting floating floating bodies used as a floating pier or the like.

[Conventional technology]

In floating piers, etc., that connect multiple floating bodies, the joints and other floating bodies may be damaged by the impact of the wave height and the contact of the boat on the floating body. There have been proposed various connecting structures for floating bodies which prevent damage to the floating bodies.

For example, as shown in Japanese Patent Laid-Open No. 62-82102, inner and outer support members are provided on the inner surface and outer surface of the side wall of a floating body as cushioning members to serve as supporting means, and the outer side of the supporting means for adjacent floating bodies is provided. Connect the support members with each other with bolts,
A connection structure of floating bodies on the water has been proposed in which the shock energy of the connection portion can be absorbed by a buffer member.

[Problems to be solved by the device]

With such a connecting structure, since the inner supporting member is provided on the inner surface of the side wall of the floating body, the supporting means is attached beforehand when the floating body is manufactured, and the supporting means is attached at the assembly site of the floating body. It is difficult.

When the external force or buffer is relaxed, a shearing force acts on a bolt connecting adjacent support means, and the bolt may be broken.

Then, this invention aims at providing the connection structure of the floating body which can solve the above-mentioned subject.

[Means and Actions for Solving the Problems]

A second elastic body is provided between the first bracket attached to one floating body and the second bracket attached to the other floating body, and is swingably supported by the first elastic body provided on the inner surface of the first bracket. The rod penetrates the first bracket, the second elastic body, and the second bracket, and is swingably supported by the second bracket, so that the impact energy due to the relative movement of both floating bodies can be absorbed by the first and second elastic bodies. It can be relaxed by compression, and the connecting rod slides and swings with respect to the first and second brackets so that shearing force does not act.

〔Example〕

As shown in FIG. 1, a first bracket 3 having a substantially U-shaped plane is attached to an end surface 2 of one of the adjacent floating bodies 1 by a bolt 4, and an end surface 6 of the other floating body 5 is substantially U-shaped in a plane. The second bracket 7 is attached with a holt 8.

One side of the hollow first elastic body 9 is connected to the inner surface of the first bracket 3 by a bolt 10, and the plate 11 is attached to the other side of the first elastic body 9 by a bolt 12. A hollow second elastic body 13 is provided on the outer surface of the bracket 7.
Both sides of are attached with bolts 14 and 15, and the plate 1
A cylindrical receiving body 17 having a spherical concave portion 16 concentric with the through holes 11a, 7a is fixed to the inner surfaces of the first and second brackets 7, respectively, and a spherical body 18 is formed in the spherical concave portion 16 of each receiving body 17. Hollow connecting rod 19 that is fitted into each other and penetrates the first and second brackets 3 and 7 and the first and second elastic bodies 9 and 13 between the one spherical body 18 and the other spherical body 18. Is provided with one spherical body
Insert the bolt 20 from 18 into the connecting rod 9 and the other spherical body 18 and tighten the nut 21 to attach the first and second brackets 3 and 7 to the first and second.
The second elastic bodies 9 and 13 are connected to each other.

The first and second elastic bodies 9 and 13 do not need to be connected with bolts, only one side may be connected with bolts, and the spherical bodies 18 are respectively attached to both end surfaces of the connecting rod 19 with bolts. You may connect.

 Next, the operation will be described.

When one floating body 1 moves upward in FIG. 1, the first bracket 3 compresses the first elastic body 9 and moves the connecting rod 19 upward through the spherical body 18, and this force is applied to the other spherical body. The other floating body 5 on the water is moved upward through the spherical surface of 18, the spherical concave portion 16 of the receiving body 17, and the second bracket 7. By this movement, the second elastic body 13 is compressed and the impact energy is relieved. It

When one floating body 1 moves downward in FIG. 1, the second elastic body 13 is compressed through the first bracket 3 and the second floating body 13 is compressed.
The other floating body 5 on the water is moved downward via the bracket 7, and the first elastic body 9 is compressed along with the movement, thereby relaxing the impact energy.

When the other floating body 5 moves upward in FIG. 1, the second elastic body 13 is compressed via the second bracket 7 and the one floating body 1 is moved upward via the first bracket 3. With this movement, the impact energy is relaxed by the compression of the first elastic body 9.

If the other floating body 5 moves downward in FIG.
Bracket 7, receiving body 17, spherical body 18, connecting rod 19, spherical body
The first elastic body 9 is compressed via 18, the receiving body 17 and the plate 11, one of the floating bodies 1 is moved downward via the first bracket 3, and the compression of the second elastic body 13 is accompanied by this movement. Impact energy is relieved.

When one floating body 1 moves laterally in FIG. 1, the first and second elastic bodies 9 and 13 move in the circumferential shearing direction via the first bracket 3 and the second bracket 7 via the second bracket 7. The other floating body 5 is moved, and the difference in this movement is adjusted by the fitting portion of the spherical body 18 and the spherical recess 16 of the receiving body 17.

That is, the impact energy is relieved by the compression of the first and second elastic bodies 9 and 13 with the relative displacement of both floating bodies 1 and 5 in the lateral direction, and the spherical body 18 receives the difference in the displacement at this time. It swings along the spherical recess 16 of the body 17.

With respect to the movement of both floating bodies 1 and 5 in the twisting direction, the impact energy is relieved by the twisting of the second elastic body 13 via the first bracket 3 and the second bracket 7.

As described above, since the first and second elastic bodies 9 and 13 mainly act in the compression direction to absorb the impact energy, the impact between the adjacent floating bodies 1 and 5 is improved while improving the durability of the elastic body. Since the energy is relaxed, the connection structure has practically excellent durability.

FIG. 2 shows a second embodiment, in which outwardly facing flanges 9a and 13a are integrally provided on the first and second elastic bodies 9 and 13, respectively.
9a and 13a are attached with bolts.

[Effect of device]

The first and second elastic bodies 9 and 13 are compressed by the relative movement of the floating body 1 on the one hand and the floating body 5 on the other hand, and the impact energy is relieved thereby, so that the elastic bodies have excellent durability. The connecting rod 19 has the first and second brackets 3,
Sliding and swinging displacement with respect to 7 does not cause shearing force, so there is no breakage, and the first and second brackets 3,
7 is previously connected to the first and second elastic bodies 9 and 13 with a connecting rod 19 or the like,
The first and second brackets 3 and 7 can be attached to the end surfaces of the floating bodies 1 and 5 at the assembly site of the floating bodies 1 and 5, thus facilitating the work of connecting the floating bodies.
