Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floating block for a floating structure, and particularly to a floating block constituting a large floating structure.

As floating structures become larger, it becomes difficult to construct them as one piece, so floating blocks, which are partial structures, are constructed in advance and these floating blocks are joined on the water.

In this case, if we were to join them by welding, it would be necessary to fix the welded points in some way for a certain period of time to prevent the blocks moving on the water surface from separating from each other. requires a huge amount of man-hours.

In addition, because welding workability is poor, it is difficult to improve the joining accuracy.

This invention was made in view of the above circumstances, and
The purpose is to provide floating blocks for a floating structure that can be easily connected on the water and thereby constitute a robust floating structure.

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in the drawings.

The floating block 10 has a horizontal upper surface 11 and a lower surface 12, has a regular hexagonal shape when viewed from above, and has six side surfaces 13.
is assumed to be vertical.

Six cylindrical support floats 14 are fixed at symmetrical positions on the lower surface 12 of the block.

Each of the three consecutive side surfaces 13 of the block 10 is provided with a horizontally protruding convex portion 15 at an intermediate portion thereof in the vertical direction.

On the upper side of the convex portion 15, there is an inclined surface 1 that is inclined downwardly toward the outside.
6 is formed, and an inclined surface 17 that is inclined outwardly and upward is formed on the lower side of the convex portion 15, and both end surfaces 18 of the convex portion 15 are on the same plane as the adjacent side surface.

Further, each of the convex portions 15 is provided with two connecting elongated holes 19 that vertically penetrate through the convex portions 15 .

The remaining three side surfaces 13 of the block 10 are provided with horizontal recesses 20 at the same height as the projections 15.

The recess 20 is continuous across three side surfaces, and has an inwardly downwardly inclined inclined surface 21 formed on its upper side, and an inwardly upwardly inclined inclined surface 22 formed on its lower side. It is formed.

Elongated connecting holes 23.24 that vertically penetrate the block 10 are formed in the upper and lower inclined surfaces 21.22 of the recess 20.

Two elongated holes 23 and 24 are provided for each recess, and the upper end of the upper elongated hole 23, that is, a part of the block top surface 11 is cut out to form a seat 25 for a connecting member.

All three convex parts 15 are at the same height and have the same shape, and all three concave parts 20 are also at the same height and have the same shape, so that the convex part 15 fits into the concave part 20 of the other block 10. Accordingly, both blocks 10 are of the same height.

When the convex portion 15 and the concave portion 20 are in a fitted state, the block side surface 13 and the side surface 13 of the other block 10 are in close contact with each other, and the concave portion 2
The elongated holes 23 and 24 of 0 are connected to the elongated hole 19 of the convex portion 15, and the elongated holes 23, 19, and 24 vertically penetrate through the block 10.

At this time, the slopes 16 and 17 above and below the convex portion 15 are connected to the concave portion 20.
It is preferable to contact the upper and lower inclined surfaces 21 and 22, respectively.

To connect two floating blocks 10, the protrusion 15 of one block 10 is fitted into the recess 20 of the other block 10, and the elongated hole 19 of the protrusion 15 is inserted into the elongated hole 23 of the recess 20.
24, and connect the connecting member 26 to the elongated hole 23°19.24.
Just plug it in.

By inserting the connecting members 26 into the two sets of long holes 23, 19, and 24, the floating blocks 10 will not be separated from each other.

The convex portion 15 and the concave portion 20 are inclined surfaces 16, 17, respectively.
18 and 19, it is easy to fit, and it can be made even easier by applying oil or the like to these.

Further, since the head 27 of the connecting member 26 is sunk into the notch of the seat 25, it does not get in the way (see FIG. 5).

In order to construct a floating structure using the floating blocks 10, a large number of blocks 10 may be connected one after another in the manner described above.

At this time, for example, as shown in FIG. 4, if all the blocks 10 are arranged with their convex portions 15 (or concave portions 20) facing the same direction, the side surfaces 13 of the two blocks 10 The convex part 15 and the concave part 20 always face each other at any position where they meet, and a floating structure can be constructed by arranging a large number of blocks 10 with gaps between them.

However, the orientation of the blocks 10 does not have to be limited to the above-mentioned orientation, and of course they can be connected in an infinite number of ways even if the orientations are not aligned.

In the floating structure constructed in this way, the connections between the blocks 10 are not continuous in a straight line, so the connections are strong and a robust structure can be obtained.

Moreover, since the already connected blocks 10 serve as guides, positioning when connecting new blocks 10 becomes easy.

In this embodiment, the convex portions 15 and the concave portions 20 are provided on three consecutive surfaces, but the arrangement thereof is arbitrary. For example, the convex portions 15 and the concave portions 20 may be provided alternately.

Furthermore, the block 10 is not limited to having a regular hexagonal planar shape, and may have a hexagonal shape that is symmetrical with respect to one point, as shown in FIG. 6 or FIG. 7, for example. .

In this case as well, only one type of block 10 (one in which three convex portions 15 and concave portions 20 are provided in succession, or one in which convex portions 15 and concave portions 20 are provided alternately) can be used on the water. Structures can be constructed.

In addition, in FIGS. 6 and 7, the same parts as in the above-mentioned embodiment are given the same reference numerals.

That is, the planar shape of the block 10 may be any shape as long as it allows a floating structure to be constructed by arranging a large number of blocks 10 of one type in which the positions of the convex portions 15 (or concave portions 20) are fixed without gaps.

As described above in detail, according to the present invention, a large number of blocks 10 are fitted into each other by fitting their convex portions 15 and concave portions 20, and connecting members 2 are inserted into their connecting holes 23, 19, 24.
A large floating structure can be constructed by connecting the blocks 6 by simply inserting them, and since the already connected blocks 10 serve as a guide, the positions can be easily determined and the connection is simple.

Since the block 10 has a hexagonal shape when viewed from above, the mutual connections are not continuous in a straight line (the connections are strong, and a robust floating structure can be obtained).

In addition, all blocks are connected to the convex portion 15 (or concave portion ν20
) can be made to have the same shape, including the location, so mass production is possible and manufacturing costs can be reduced.

Further, the blocks 10 can be appropriately connected to form a structure of any shape and size.
