Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating island assembly block which is floated or fixed on the surface of the water and then used for leisure or leisure.

[0002]

2. Description of the Related Art Floating islands that are conventionally floated on the surface of the water, or fixed on the surface of the sea, and used for leisure, have a framework such as a steel frame established on the seabed, and iron or It was carrying a girder such as concrete. In addition, bamboo rafts and wooden rafts were used to float on the surface of the water.
In the case of using a steel frame, it is necessary to securely fix the skeleton to the seabed, etc., which requires much labor for assembling and disassembling, and there is a cost problem. Also, those using bamboo rafts and wooden rafts were cheap, but it was difficult to collect and fix timber etc. because it was not fixed to the seabed etc., so it is not possible to work on it It was difficult. Especially, it could not be installed in a place where the waves were high or the flow was fast.

A buoyant force which can be easily assembled and disassembled, whose size, buoyancy force, fixed portion, strength and the like can be arbitrarily selected, and which enables safe operation. A body building block is provided.

[0004]

First, a buoyant body block in which a gas such as air is sealed is used. Since it has a double structure with an air chamber in which gas is sealed inside, it is strong against external impacts and floats above the water surface alone, or can withstand water pressure at a certain depth. A convex portion and a concave portion were provided on the outer peripheral side surface of the buoyancy body block, and the convex portion and the concave portion of the adjacent blocks having the same shape were fitted and fixed. Since the blocks can be assembled simply by fitting the adjacent blocks, the assembling and disassembling can be performed easily and surely.

Secondly, screw holes are provided at four corners of the buoyancy body block. The buoyant body blocks provided with the screw holes are stacked in a plurality of stages, and bolts are screwed into the screw holes to fix the blocks in a plurality of stages. As a result, the buoyancy can be adjusted according to the weight, and even heavy objects can be stably operated on the water surface.

Thirdly, a buoyant body block having through holes provided in the vertical direction is arranged at an arbitrary position. A pillar is inserted into this through hole and the lower end is fixed to the seabed or the like. As a result, the floating island assembly block is fixed, and it is structured so that it does not move up or down due to waves or water flow, or when the tide is full.

Fourthly, since a lateral beam guide groove extending in the lateral direction is provided on the side surface of each block and the lateral beam is attached to the Annai groove, the assembly block does not come off in the vertical direction.
Strength becomes stronger.

Fifth, a through hole penetrating in the lateral direction is provided, and a supporting rod is inserted into the through hole. Similar to the fourth, the assembly block does not come off in the vertical direction, and the strength is increased.

[0009]

The present invention is constructed as described above,
The opposing concave and convex portions of adjacent buoyancy blocks are fitted together, and a buoyancy block having vertical through holes is arranged in part of the buoyancy blocks, and columns are inserted into these through holes. However, this support may be placed on the bottom of the water or fixed in water. Further, since lateral beam guide grooves formed in the lateral direction are continuously formed on the outer surface of each block, the lateral beams are attached to the lateral beam guide grooves to form a floating island assembly block.

1 is a perspective view of a buoyant body block according to the present invention. 1 is excellent in durability and impact resistance, for example, ABS
Alternatively, it is a quadratic prism type buoyancy body block made of synthetic resin such as polycarbonate resin, and the buoyancy body block is provided with an air chamber in which air or a gas lighter than air such as helium is sealed. (See FIG. 9) The buoyant body block 1 can be fitted with the convex portion 3 having a wide tip on two adjacent sides of the outer surface and the convex portion 3 having a narrow opening on the other two sides. Recessed portions 4 are formed in a vertical shape, and screw holes 5 are formed at the four corners to penetrate the upper and lower portions. The screw hole 4 has a screw groove formed in the upper and lower portions of the inner peripheral surface thereof.

Further, a lateral beam guide groove 6 formed in the lateral direction is formed in the central portion of the outer surface of the buoyancy body block 1, and the lateral beam guide groove 6 is formed in a trapezoidal shape with a narrow opening. As shown in FIGS. 8 to 10, the buoyant body block having such a structure is fitted with the concave and convex portions of the adjacent blocks, which are opposed to each other, and the blocks are assembled in the vertical and horizontal directions. The buoyant body blocks 1 stacked in the same direction are also fixed by bolts 8 that pass through the screw holes 5.

The horizontal beam guide groove 6 of each block 1 is also formed on the back side of the convex portion 3 on the outer side surface, and the horizontal beam 9 is fitted into the long continuous guide groove 6 to form the floating island assembly block 7. The outer circumference of was fitted and reinforced by the cross beam 9.

As shown in FIG. 9, a buoyant body block 1 having a through hole 10 penetrating in the vertical direction is provided outside the floating island assembly block 1, and the column 1 is inserted into the through hole 10 and the column 11 is penetrated. It fixed to the hole 10 and the floating island assembly block was fixed to the water bottom. Further, the buoyant body block 1 is arranged at a position where the through hole 10 is continuous with the through hole 10 penetrating in the lateral direction, and a column is inserted into the through hole 10.

In the example of FIG. 10, the bolt 8 inserted into the screw hole 5 is inserted.
Is extended downwards, and the buoyant body assembly block is fixed to the bottom of the water like the support. Note that reference numeral 12 in FIG. 1 is a groove for preventing slippage provided on the upper and lower surfaces of the buoyancy body block.
13 is a nut for adding the bolt 8.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, it is possible to easily and reliably assemble a workbench or a floating island block for leisure that is floated or fixed on the water surface. In addition, floating island blocks can be easily assembled by simply fitting adjacent blocks, to those with horizontal beams installed to increase safety. It can be assembled in various ways. Furthermore, by stacking multiple stages, the required buoyancy can be easily selected. In addition, if a pillar is attached to the block, the floating island assembly block is fixed to the bottom of the water, and the work table becomes immovable, which has the effect of improving safety.
