DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating pier connecting structure for a marine leisure marina.

[0002]

2. Description of the Related Art A floating pier for a marine leisure marina is formed by connecting a plurality of pier units 10 each having a rectangular plate shape with a float 30 attached to a lower surface in one direction. Are used, and are roughly classified into a solid type and a flexible type. Further, as shown in FIGS. 1 and 2, the former solid type is a bolt fastening type in which the end faces of adjacent pier units 10 are aligned, rubber materials 25 and washers 26 are disposed, and bolts 20 and nuts 21 are completely fixed. And the float are fixed with a deck frame, and the deck unit is connected to the deck frame connecting type, which assembles the entire pier unit.The latter flexible type is connected to the pin hinge type, which connects the pier unit with pins and hinges, and the chain and wires. Each type has its own advantages and disadvantages, and is selected according to the sea conditions (wave height, wavelength, etc.) of the installation location, the length of the floating pier, the strength of the pier unit, the strength of the connecting portion, and the purpose of use.

[0003] Generally, in a still water area where a leisure marina is located, in a breakwater, in a natural cove, etc., the wave height is usually 50 to 60 cm level, and it is about 1 m at an abnormal time. There is a problem that it can cope only up to a wave height of about 30 cm because it concentrates on the part (particularly the bolt 20). In addition, the deck frame connection type is designed to absorb deformation due to external force in the whole floating body, so it can be applied only to small things up to about 12 m for steel, and 5 to 12 m for pin hinge type Although it is used for things, the wear is severe, the noise is loud, the stability of the floating body is uneasy, and the chain / wire type is loosely connected, so the floating body body shakes violently, and the burden on it There are problems such as large.

[0004]

The problem to be solved is that the connection structure of the above-mentioned conventional floating pier has advantages and disadvantages, and for a marine leisure marina, the bolt fastening type only supports up to a wave height of about 30 cm. No, the deck frame connection type can be applied only to small things up to about 12 m, and the pin hinge type has severe wear of the connection part, loud squeaking noise, and there is concern about the stability of the floating body, In the wire type, the main body of the floating body is violently shaken, and the burden on the body is large.

[0005]

A description will be given with reference to FIGS. The present invention relates to a connecting structure of a floating pier for a marine leisure marina, in which a plurality of rectangular plate-like pier units 10 each having a float 30 attached to its lower surface are fastened by bolts 20 and connected in one direction. 1
0 comprises a plurality of vertical U-shaped steel vertical frames 11 arranged in parallel in the longitudinal direction and a horizontal frame 12 for integrally connecting the vertical frames 11, and a base is provided on a vertical inner surface at one end of the vertical frame 11. The projecting portion of the fixed connecting plate 13 is inserted into the adjacent vertical frame 11, brought into contact with the corresponding vertical inner surface, and fastened by the bolt 20.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG.
Is a pier unit constituting a floating pier in the form of a rectangular plate, comprising a plurality of vertical U-shaped steel vertical frames 11 arranged in parallel in the longitudinal direction and a horizontal frame 12 integrally connecting the vertical frames 11. Become. Reference numeral 13 denotes a connecting plate having a base fixed to one end of the vertical frame 11 at a vertical inner surface, and the protrusion is tapered so that it can be inserted into the adjacent vertical frame 11. Reference numeral 14 denotes a plurality of bolt holes formed in the connecting plate 13 in the longitudinal direction, and reference numeral 15 denotes a plurality of bolt holes formed in the other vertical inner surface of the vertical frame 11 and correspond to the bolt holes 14. The bolts and nuts 20 and 21 are for aligning and inserting the corresponding bolt holes 14 and 15, and the bolts and nuts for fastening the vertical inner surface of the adjacent vertical frame 11 to the connecting plate 13 are mounted on the lower surface of the pier unit 10. Float.

The operation will be described. When the connecting plate 13 is inserted into the vertical inner surface of the adjacent vertical frame 11, the two are brought into contact with each other, the bolt holes 14 and 15 are aligned, and the bolts 20 and the nut 21 are used to fasten. Pier unit 10,
10 is rigidly connected.

[0008]

The present invention is constructed as described above, and furthermore, the adjacent pier units 10, 10 are connected by frictional connection between the connecting plate 13 and the vertical inner surface of the adjacent vertical frame 11, so that the weight is reduced. Connection work becomes easier, the stability of the floating body and the durability of the connection structure are improved, and the normal wave height of 50-60 cm in the still water area where the leisure marina is located, inside the breakwater, natural cove, etc., when abnormal It is strong against lateral load (horizontal force) for wave conditions of about 1 m, and can absorb the stress of longitudinal load by the deflection in the elastic deformation of the constituent material. Furthermore, by designing the stress generated in the connecting plate 13 to be smaller than the stress generated in the main body, the wave force received by the floating pier can be absorbed not locally but as a whole, and endless connection is also possible. . In addition, the level of the above-mentioned application conditions can be further improved by taking measures against the belly phenomenon of the float 30 and considering the influence of the floating jetty flooding.
