DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure of a floating structure constituting a floating pier installed at a seaside or a waterside such as a marina or a yacht beach.

[0002]

2. Description of the Related Art A conventional floating pier is shown in FIG.
In many cases, a plurality of floating structures 21 having a hollow float 20 made of polyethylene or the like are connected. That is, in this floating pier, the floating structure 21 formed in a substantially hexahedron is arranged such that the ends of the plurality of floating structures 21 are adjacent to each other, and the adjacent floating structure 2
The connecting piers 1 and 21 are connected by a connecting member 23 to form a floating pier.

However, the conventional floating pier has the following drawbacks because the ends of adjacent floating structures are connected to each other by a rigid member. (1) Every time the floating structure swings up and down, the load (stress) is concentrated only on the connecting portion at the end of the floating structure, so that the life of the floating structure is shortened. (2) A floating jetty is installed Depending on the environment and customer requirements
Alternatively, it is desirable to change the rigidity of the connecting mechanism of the floating pier in accordance with a place where there are many waves or sailing waves, but the conventional connecting structure cannot cope with this. In other words, in places where there are many waves and sailing waves, it is better to make the connection function flexible when emphasizing the durability of the floating pier, and in the calm area where there are few waves and sailing waves, focus on the stability of the floating pier. Although it is preferable to increase the rigidity of the connecting mechanism, the connecting mechanism of the conventional floating pier cannot adjust the rigidity of the connecting mechanism depending on the environment and circumstances.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned drawbacks, and an object of the present invention is to prevent a load from being concentrated on a connecting portion at an end of a floating structure. Accordingly, an object of the present invention is to provide a connection structure of a floating structure that can prolong the life of the floating structure.

Another object of the present invention is to provide a connecting structure of a floating structure capable of changing the rigidity of a connecting mechanism of a floating pier in accordance with an environment in which the floating pier is installed, an installation condition, and the like. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings.

The floating pier A is constituted by connecting a plurality of floating structures 1 as shown in FIGS. The shape of the floating pier A can be variously changed depending on the manner of connection between the floating structures 1, 1,....

The floating structure 1 has a float 3 and a spacer 2 mounted on a flange 4 of the float 3. The spacer 2 and the float 3 may be formed integrally, or may be formed separately and attached by a fixing tool such as a bolt. The spacer 2 is usually formed of metal, but may be formed of wood, laminated wood, or the like. The float 3 is formed of a synthetic resin material or a composite material of a synthetic resin and another material.

A plurality of such floating structures 1 are arranged with a gap therebetween.

A connecting member 10 is provided on the upper surface of the spacer 2 of each floating structure 1, and the connecting member 10 is fixed to the spacer 2 by fixing means 5 such as bolts and nuts.

The connecting member 10 is composed of a tubular (for example, square tubular) member, an L-shaped angle member, a member having an I-shaped cross section, and the like. In the embodiment shown in FIGS. 1 and 2, the connecting member 10 is formed of a square steel pipe, and as shown in FIG. 4, rectangular openings 11 are formed at both ends of the connecting member 10. Slit 12 leading to the end on both side pieces of
Are formed. Therefore, the gap between the upper piece 10a and the lower piece 10b on the end side of the connecting member 10 can be changed.

As shown in FIG. 1, three connecting members 10 are fixed on the floating structure 1 in parallel, and the connecting members 10 of another floating structure 1 which are laterally adjacent to each other by a horizontal member 18.
Are fixed to each other. In this case, the connecting member 1
The gaps formed between zeros are provided at the same location in the plurality of connecting members 10 so that the plurality of gaps are linear. Usually, two or more connecting members 10 are provided for each floating structure 1.

Although the length of the connecting member 10 can be appropriately changed, the connecting member 1 fixed on the upper surface of the floating structure 1
0 is set to such an extent that it protrudes laterally from the edge of the floating structure 1. The connecting member 10 may be mounted and fixed on the float 3 via the spacer 2 and the horizontal member 18 as described above, or may be mounted and fixed on a flange of the float 3.

The connecting piece 14 is formed of an elastically deformable member, and can have, for example, a laminated structure of an elastic body and a substantially rigid plate. Specifically, as shown in FIG. 3, a metal core 16 is disposed between both ends of a pair of elastically deformable resin plates 15, and steel plates 17 are further laminated on upper and lower surfaces of both ends of the resin plate 15. It is configured. These members may be laminated and adhered, or may be fixed by metal fittings or the like. When the length of the connecting piece 14 is 500 mm and the vertical thickness of the end 14a is 70 mm, the thickness of the resin plate 15 is 12 to 2
0 mm, and the thickness of the core 16 is 16 to 34 mm
And the thickness of the steel plate 17 is 4.5 to 16
mm. Further, a rubber piece that can be elastically deformed may be used instead of the resin plate 15. This connecting piece 14
In this case, the cross-sectional shape and dimensions or the material are adjusted so that the overall bending rigidity becomes a target value.

The end 14a of the connecting piece 14 has a rectangular cross section and a size such that it can be inserted into the opening 11 of the connecting member 10.

Floating structure 1 constructed as described above
As shown in FIGS. 1 and 2, a plurality of adjacent floating structures 1, 1 are arranged so that the connecting members 10 fixed to the upper surface of the floating structure 1 are aligned, and The two ends 14a of the connection piece 14 are inserted into the openings 11 at the ends of the connection member 10 of the floating structure 1 to be formed. Next, when the bolt is passed through the connecting member 10 and the connecting piece 14 and tightened with a nut via a washer, the slit 12 is formed at the end of the connecting member 10 so that the upper piece 10a of the connecting member 10 is bent. And the insertion end 1 of the connecting piece 14
4a is sandwiched between the upper piece 10a and the lower piece 10b of the connecting member 10. Here, a bolt hole 19 is formed at an end portion of the connecting member 10, and a bolt hole (not shown) is provided in an insertion portion of the connecting piece 14 at a position corresponding thereto. Although the number of bolt holes can be changed as appropriate, in this embodiment, two bolt holes are provided in the longitudinal direction at intervals of about 60 mm.

A surface plate is placed on a grid composed of the horizontal members 18 and the connecting members 10 framed on the floating structure 1.

[0022]

According to the present invention, the load (bending moment) applied to the floating structure is borne by the connecting member and the connecting piece, and the load (stress) is concentrated on the main body and the connecting portion of the floating structure. Therefore, the life of the floating structure can be extended.

Further, the bending rigidity of the floating structure can be set by the material and dimensions of the connecting member or the connecting piece, and the bending rigidity of the floating pier constituted by the floating structure is adjusted to the installation condition. Can be adjusted. Therefore,
