Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating jetty suitable for accommodating a small vessel or the like, and in particular, it can be assembled or disassembled on land and requires no work underwater at the time of installation or removal. Not about floating slopes.

[0002]

2. Description of the Related Art Conventionally, concrete fixed slopes have been provided and used as a hoisting or mooring system in a harbor or the like where dinghys, watercrafts, small boats, etc. However, such a fixed slope has a drawback that it requires a separate pier for temporary mooring and is slippery and dangerous, though it costs a lot of construction cost. Further, such a fixed type is not suitable for use as a temporary hoisting / mooring space for various events.

In many cases, the fixed slope is installed so as to cut into the land from the front of the revetment, which may occupy the area of the onshore facility, and it is extremely difficult to upgrade or add it. It is necessary to have a particularly strong structure in the part where the open sea swell is entered. Therefore, there is a drawback that not only the technical burden but also the construction cost becomes heavy and the construction period becomes long. In other words, the foundation work requires dredging, ground improvement, and large-scale underwater foundation work such as pile or sheet pile foundation as well as the revetment work, and it is not enough to use the work pontoon for the main body construction. Underwater work using is required.

[0004] Further, since algae adheres to the portion of the slope below the high tide line, it is very slippery, which is dangerous for beginners and children to use, and it slides over a wide range at low tide. There was also the inconvenience that the ship could not be pulled up without it. In addition, since fixed slopes are inconvenient for temporary mooring of ships, in the end there are many situations in which separate piers, passages, stairs, etc. must be installed for temporary mooring, which is a disadvantage of waste. there were.

The drawbacks of such a fixed slope have been remarkably improved by the floating pier structure described in Japanese Patent Laid-Open No. 9-78527. However, this floating pier
Since the main bridge, intermediate bridge and tip bridge are large in size, and the free end of the tip bridge can be appropriately pushed above the water, the inclination angle of the tip bridge depends on the water level. Since there is a change, it is difficult to practically pull up a ship or the like when the angle of inclination becomes large, and the installation cost also becomes high.

[0006]

Therefore, the present inventors
A further examination of a small, easy-to-use, inexpensive floating pier revealed that a horizontal bridge part with a float on the bottom surface that forms a landing, and this is connected at a substantially fixed angle and the free end is under water. When the slope part that is immersed in is composed of blocks that can be disassembled and assembled freely and can be carried by trucks or containers, it is possible to completely eliminate the need for underwater construction, and at a low cost in a short period of time, The present invention has been achieved by finding that an easy-to-use floating pier can be constructed.

Therefore, a first object of the present invention is to provide a small floating slope which can be installed or dismantled at low cost in a short period of time and which is excellent in lifting workability for dinghys, watercrafts, small fishing boats and the like. To provide. A second object of the present invention is to provide a dinghy, a watercraft,
An object of the present invention is to provide a small floating slope which is excellent in workability for raising small recreational fishing boats and the like and which can also temporarily moor these.

[0008]

SUMMARY OF THE INVENTION The above-mentioned objects of the present invention are substantially fixed to the landing section having a float on the lower surface and the landing section moored to the tip of the pier or the pier via an overhanging slope. A floating slope having a slope part fixed at an inclination angle of, comprising a plurality of blocks that can be assembled as a large panel on land, and the blocks are sized to be transported by a container or a truck. Achieved by a floating slope to In particular, it is preferable that at least one side portion of the slope portion has a sleeve portion that can be substantially regarded as an extension of the landing portion.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described with reference to Examples, but the present invention is not limited thereto. FIG. 1 is an elevation view of a floating jetty of the present invention according to claim 1. Reference numeral 1 in the figure is a landing portion, and has a float 3 on the back surface. Reference numeral 2 is a slope portion, and has a float 3 provided as necessary. Since the slope 2 is shorter than the overhanging slope 20 described later, it is not required to have the same strength as the overhanging slope, but if it becomes large, it should be reinforced with wires or the like as in the case of the overhanging slope. Is preferred. The float 3 may be appropriately designed and provided in size and number according to the size and weight of the jetty. Float 3 is made of plastic, FRP,
It is made of corrosion-resistant material such as alumite, stainless steel, etc. and is detachably attached with bolts.

The landing section and the slope section are separately assembled and fixed and connected using a connecting member so that a certain angle is formed. However, it is preferable that the angle has some play at the time of use. It is preferable from the viewpoint of preventing excessive force from concentrating on the continuous portion due to waves or the like. Particularly in the case of a small floating slope, the landing section and the slope section may be formed into a unit, and the flat panel unit may be connected to the plane forming the corner to form the landing section and the slope section. . Also in this case, it is preferable to have a structure in which there is play at an angle so that it is not difficult to pull up the ship, etc., in order to prevent damage to the floating slope. These units may be composed of smaller units.

In the present invention, these units are combined to form a block, and the blocks are combined to form a floating slope. If the unit is large, it can be called a block as it is. The floating slope depends on its overall size,
When the size is such that it can be suspended by a crane, it may be assembled entirely on land, but it is also possible to assemble them in blocks and integrate them on water.

FIG. 2 is an enlarged elevational view of the overhanging slope 20. In the figure, reference numeral 2 is a slope portion, 3 is a float,
4 is a reinforcing wire for holding the structure of the slope part,
Reference numeral 5 is a wire support portion, 6 and 7 are wire fixtures, and at least one of them is provided with a wire tension adjusting fitting. The float 3 may not be provided if there is no risk of contact with the water surface.

FIG. 3 is a plan view of a structure in which a part of the slope is cut away. Reference numeral 8 in the drawing is a surface portion, and in most cases is a wood portion, on which an appropriate slip stopper is provided. Reference numeral 9 is a backside breathing, and reference numerals 10, 11 and 12 are frame portions although they have different thicknesses. This structure is applicable not only to floating slopes but also to landing areas and overhanging slopes. Also, FIG.
FIG. 8 is a diagram showing an example of use in which the yacht is moored to the pier having the landing section and the slope section of the present invention, or is raised on the pier. In this case, the left half of the slope is submerged in water. When the surface of the water is rough due to strong wind, the floating slope of the present invention can be moved to a safe place without mooring to prevent damage due to stormy weather.

FIG. 5 and FIG. 6 are a plan view and an elevation view of an embodiment showing a use state of the jetty according to the invention of claim 2, respectively. In the figure, reference numeral 1 is a landing portion, 1'is a sleeve portion in which the landing portion is extended, 2 is a slope portion, and 3 is a float. Since the pier of the present invention has the sleeves, it is possible to secure a large number of mooring points and it is easy to pull up the ship. In the present invention, the frame is standardized, and after the frame is assembled, the unitized surface portion 8 or the breathing portion 9 may be attached, or the surface portion 8 with the frame or the breathing portion 9 may be attached.
May be unitized and these may be assembled.
