Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating jetty moored on water or at sea.

[0002]

2. Description of the Related Art Conventionally, a general floating pier is constructed by first assembling a wooden pier frame, and then connecting the pier frame to a string,
A buoyant body (float) is tightly bound with a metal band or the like to form a buoyant structure, which is transported and used on water or at sea.

[0003]

However, in the conventional floating pier, a large number of binding members must be prepared in order to fix the pier frame and the buoyancy body, and the buoyancy body is surely fixed. Therefore, there was a problem that a large amount of time had to be spent. Further, in the floating pier thus assembled, there is a problem that the buoyancy body is not accurately arranged, so that the balance is not good when the levitation body is levitated.

In view of the problems of the conventional floating jetty as described above, the present invention provides a floating jetty that does not require a binding member, can be easily assembled, and has a good balance when it is floated. With the goal.

[0005]

DISCLOSURE OF THE INVENTION The present invention is a floating jetty in which a recess capable of holding a block-shaped buoyancy body is provided on the lower surface side of the floating jetty main body, and the buoyancy body is housed and fixed in the depression.

The floating pier body is composed of an F-shaped bridge.
It can be formed by an RP frame and a resin floor material laid on the FRP frame. Further, it is preferable that the edge portion of the FRP frame is provided with a connecting means for connecting the plurality of floating pier bodies to each other.

[0007]

According to the present invention, if the block-shaped buoyancy body is held in the recess provided on the lower surface side of the floating pier body by, for example, press fitting, positioning and assembly of the buoyancy body is completed and the floating pier is completed. However, after being floated above the water or the sea, the buoyant body is fixed in the recess by buoyancy.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an assembly diagram showing a configuration of a floating jetty according to an embodiment of the present invention. In the figure, the floating jetty is mainly composed of a floating jetty main body 10 and a block-shaped buoyancy body 20.

The floating pier main body 10 is an F
An RP frame 11 and an FRP floor panel (hereinafter abbreviated as floor panel) 12 as a resin floor material laid on the FRP frame. FRP frame 1
The individual members constituting 1 are C-shaped channels 11a, 11b, 11c and 11d made of FRP in the longitudinal direction and C-shaped channels 11e, 11f, 11g and 1 made of FRP in the lateral direction.
1h, each of the frames A to D has a C-shaped channel arranged so as to be surrounded by a surface 11i of the C-shaped channel 11a opposite to the groove side. This is to increase the contact area of a portion that comes into contact with the buoyancy body, which will be described later, and to smoothly attach the buoyancy body.

The connecting portion of each C-shaped channel is L
Each C-shaped channel is reinforced with a V-shaped metal contact plate (not shown), and the C-channel is fixed to the two vertically intersecting C-shaped channels with bolts and nuts. I am working with. Also, the FRP frame 11
An eyeglass bolt 13 as a connecting means for connecting a plurality of floating pier bodies to each other is attached to the edge portion of the.

The four buoyant bodies 20 have a specific gravity of 0.02.
.About.0.04 Styrofoam, and the above A to D
Each frame is cut according to the inner dimension of each frame so that it can be held in each frame. The surface of the buoyancy body 20 may be subjected to a surface treatment such as applying a water-repellent coating, depending on the purpose of use.

FIG. 2 is an enlarged view of an essential part showing a fixed state of the floor panel 12. In the figure, the upper surface of the floating pier is
A passage is formed by laying a large number of floor panels 12 in a state where their ends are overlapped. In each of the upper ribs of the C-shaped channels 11a and 11d, a through hole is formed at a position where the recess 12a of the floor panel 12 is located, and a bolt 12b is provided in the through hole.
And the nut 12c is screwed to fix the floor panel 12 and the C-shaped channels 11a and 11d. In each of the upper ribs of the C-shaped channels 11a and 11d, the buoyant force does not apply to the region where the buoyancy body 20 is not held, and therefore, the rivet may be simply fixed. In addition, the rivets 12 are provided along the longitudinal direction at the center of the portion where the floor panels 12 are overlapped.
d are struck in a row, which results in multiple floor panels 12
Are designed to be connected together. Floor panel 1
The inside of the frame A, the inside of the frame B, the inside of the frame C, and the inside of the frame D whose upper surfaces are covered with 2 can be regarded as recesses, respectively.

An assembling method of this embodiment having such a structure will be described below. The FRP frame 11 is assembled and checked in a factory in advance, and then disassembled and delivered to the site. Further, the buoyancy body 20 is also cut into a size that can be held in each of the frames A to D of the FRP frame 11, and is carried into the site. A sufficient number of floor panels 12 are prepared to cover the top of the FRP frame 11, and are delivered to the site.

At the site, the floor panels 12 are sequentially arranged from one end in the longitudinal direction of the FRP frame 11, and then the arranged floor panels 12 are fixed to the FRP frame 11 using bolts, nuts and rivets. To go. Then F
Lift the RP frame 11 and attach the four buoyancy bodies 20 to the frames A to D.
Install by press-fitting into each of them from below.
As a result, the floating jetty is completed. If the eyeglass bolts 13 of the plurality of floating piers having such a configuration are combined and connected to each other in the longitudinal direction, the lateral direction, or both the longitudinal direction and the lateral direction, a linear shape, a hook shape, a rectangular shape or the like can be arranged. A floating pier can be constructed.

Although the buoyant body of the present invention is made of styrofoam in the above embodiment, the buoyant body is not limited to this and may be a block-like one having a low specific gravity and a predetermined strength, such as rigid urethane foam and polyethylene foam. For example, any member can be used.

Further, although the resin floor material of the present invention is composed of the FRP floor panel in the above embodiment, it is not limited to this, and it has light weight, corrosion resistance, formability, and strength required for a passage. Any resinous flooring material can be used as long as it has it.

Further, although the connecting means of the present invention is constituted by the eyeglass bolt in the above-mentioned embodiment, the connecting means is not limited to this and may be any means as long as the floating pier can be connected.

[0018]

As is apparent from the above description, according to the present invention, the floating pier can be easily assembled without the need for a binding member. According to the present invention, a good balance can be obtained when levitated.
