Abstract

(57) [Summary] [Object] An object of the present invention is to provide an economical fender device capable of obtaining a reliable fender effect and shortening the length of the fender in the depth direction. According to the present invention, in a fender that absorbs shocks when a ship comes into contact with a shore, vertical guide members are installed at predetermined intervals on the revetment surface, and a floating body is mounted between the guide members so as to be vertically movable. The fender is a fender constructed by attaching a fender to the opposite side of the seawall of this floating body.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fender that absorbs an impact when a ship is docking.

[0002]

[Problems to be solved by the device]

 In the case of large ships, the berthing position is generally limited along the length of the mooring berth, so it is only necessary to attach fenders appropriately. At this time, the length of the fender in the water depth direction is required to be sufficient so as to be able to cope with the change in the berthing height of the ship due to the tidal level fluctuation, but as mentioned above, only a small number of mounting points are required. Moreover, the impact of the construction cost on the whole is small. On the other hand, in the case of small vessels, since there is a possibility of berthing along the entire length of the revetment, fenders have often been arranged densely or continuously in a plane. However, since the die depth of small vessels is smaller than the tide level fluctuation, in order for the fender to work effectively at all tide levels, a fender long in the depth direction should be used to cover the tide fluctuation range. Was needed. Therefore, the proportion of the fender on the revetment side to the total construction cost tends to be very large, and simple fenders such as old tires are attached to the hull side to avoid waiting for the fender on the revetment side. Have dealt with the way.

[0003]

[Means for Solving the Problems]

 The present invention has been made to solve the above problems, and provides an economical fender device that can obtain a reliable fender effect and can shorten the length of the fender in the depth direction. The purpose is to provide. That is, the present invention is a fender that absorbs shocks when a ship comes into berth, in which longitudinal guide members are installed at predetermined intervals on the revetment surface, and floating bodies are attached between these guide members while elevating themselves. This is a fender with a fender attached to the side of the floating body opposite the revetment.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. <A> Guide member As shown in Fig. 1, a guide member such as a guide steel 4 is vertically attached to the side surface of the seawall 3. The required number of the guide type steels 4 are installed in the lateral direction at a predetermined interval. The cross-sectional shape of the guide steel 4 is a C-shape as shown in FIG. 3, a C channel, H steel, or the like, and these are fixed to the notch 31 or the like recessed in the revetment 3 with the mounting bolt 5 or the like. In the case of the U-shape, the openings of the two guide mold steels 4 arranged at a predetermined interval face each other.

<B> Floating Body As the floating body, a hollow box type pontoon 1 or the like made of steel, concrete, prestressed concrete, or the like is used. The pontoon 1 is manufactured in the shape of a long plate as shown in FIG. 1, the lateral length is slightly shorter than the distance between the guide type steels 4, and the thickness is as shown in FIG. The thickness should be such that it can be stored loosely in the U-shape.

<C> Fender A fender 2, such as rubber, is attached to the surface of the pontoon 1 on the opposite side of the revetment 3 to absorb the impact of the ship when it comes to berth. This fender 2 has a sufficient length in the lateral direction, but only a minimum length in the depth direction.

<D> Assembly When assembling the above members, first, as shown in FIG. 1, a required number of guide steels 4 are installed on the seawall 3, and the lower end of the guide steels 4 is provided for preventing the pontoon 1 from falling. Attach the stopper 41. Next, the pontoon 1 is dropped between the guide steels 4 so that the fender 2 faces the hull side, and is floated near the water line by buoyancy. Then, one end of the fall prevention chain 6 or the like is connected to the pontoon 1, and the other end is moored to the anchor pin 61 or the like driven on the seawall 3 to prevent the pontoon 1 from coming off.

[0008]

[Action]

 Since the pontoon 1 has buoyancy, it automatically moves up and down along the guide steel 4 as shown in FIGS. Therefore, the fender 2 attached to the pontoon 1 can always be positioned near the water level line. Therefore, regardless of the change in the tide level, the fender 2 can always effectively and effectively absorb the impact when the ship is docking. Then, the horizontal force transmitted through the fender 2 is transmitted to the support structure on the side of the revetment 3 through the guide steel 4 or the back surface of the pontoon 1.

[0009]

[Effect of the present invention]

 Since the present invention is as described above, the following effects can be obtained. <B> Since the fender of the present invention has buoyancy, it automatically moves up and down according to the tide level. Therefore, it can always be located near the water level line regardless of the tide level. Therefore, the length of the fender in the water depth direction is short, and economical construction is possible.

<B> In the past, since the fender was long in the depth direction, many parts were exposed above the water surface at low tide and the landscape was spoiled. However, the present invention can contribute to the improvement of the scenery because the fenders are always the same and the exposed parts from the water surface are small.

<C> Since a reliable and economical fender effect can be obtained on the revetment side, the fender attached to the hull side is unnecessary, which is economical.

<D> When the fender is replaced or inspected, the floating body can be removed and the work can be performed on land, so that maintenance can be easily performed.
