Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cage-shaped fish reef made of metal, and more particularly to a cage-shaped fish reef having a foldable cage for easy transportation and assembly.

[0002]

2. Description of the Related Art In recent years, a basket-shaped fish reef made of metal, which is easy to increase in size and weight, has been widely used instead of a conventional concrete reef. The basket-shaped fishing reef has a basic structure such as a jungle gym in which a plurality of horizontal members and vertical members are combined into a cube or a rectangular parallelepiped, and the height of a large one exceeds 10 m.

The cage-shaped fish reef is manufactured in a factory or a yard near the quay, and the cage-shaped fish reef thus manufactured is transported to the quay, is loaded on a barge, and is sunk on the seabed.

However, the conventional basket-shaped reefs are bulky and therefore expensive to carry. In addition, since it is bulky, it involves a lot of dangerous work in high places. In order to reduce the transportation cost, an assembly-type basket-shaped reef has been proposed by Japanese Utility Model Publication No. Sho 53-21992, but there are the following problems except the transportation cost.

[0005]

By disassembling all the members and transporting them to the quay, the transportation cost is low, but a scaffold is required when assembling on the quay, and temporary construction costs are added. Moreover, since all the members are assembled on the quay, the assembly takes time and labor. Therefore, the overall economic efficiency is not as good as expected.

Further, work at a high place by using scaffolding is still required, and work safety is not improved at all.

An object of the present invention is to provide a foldable basket-type reef which is easy to transport and can be assembled easily and safely at a low place.

[0008]

The foldable cage-shaped reef according to the present invention has a unit cage formed by combining a plurality of horizontal members and vertical members made of metal into a cube or a rectangular parallelepiped, and vertically connecting the units. The horizontal and vertical members are eliminated from the front and back of the basket, and the horizontal and vertical members are freely rotatable on the four sides located at the four corners when each unit basket is viewed from the front by a spindle perpendicular to the front. To form parallel links, and detachable diagonal members are mounted between the side portions diagonally located on the four side portions.

[0009]

[Function] Each unit basket eliminates horizontal members and vertical members from the front and back of each unit basket, and at the four sides located at the four corners when each unit basket is viewed from the front,
The horizontal and vertical members are rotatably connected to the front by a spindle that is perpendicular to the front surface.When the diagonal member is removed, the upper and lower surfaces remain horizontal, both side surfaces collapse to one side, and the surface is deformed. To do. By thus deforming all the unit cages connected in the vertical direction, the respective unit cages are overlapped and folded thinly. When assembling, pull the uppermost unit basket upwards. Then, each unit basket rises up in a square shape in order from the top one. By mounting diagonal members in order on the raised unit baskets, assembly is performed in order from the topmost one. Since the assembled unit baskets are sequentially pulled up, the assembling work can always be performed at a low place.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a first embodiment of the present invention, and FIG. 2 is a front view showing the first embodiment. Further, FIG. 3 shows a connecting structure of a horizontal member and a vertical member in the first embodiment, FIG. 4 shows a mounting structure of a diagonal member, and FIG.

The basket-shaped reef of the first embodiment comprises a plurality of unit baskets 10, 10 ... Connected in the vertical direction. As shown in FIGS. 1 and 2, each unit basket 10 is a cube in which a horizontal member 11 and a vertical member 12 of equal length are combined.

On the upper and lower surfaces of the unit basket 10, a plurality of horizontal members 11 are combined in a grid pattern, and on both side surfaces, a plurality of horizontal members 11 and vertical members 12 are combined in a grid pattern. On the other hand, from the front and back of the unit basket 10,
The horizontal members 11 and the vertical members 12 are excluded. On the other hand, in the connecting portion between the adjacent unit cages 10 and 10, the horizontal members 11 forming the upper and lower surfaces are shared.

The horizontal members 11 and the vertical members 12 are four side portions 13, 13, which are located at the four corners when the unit basket 10 is viewed from the front.
Except for 13, 13, they are fixed by welding or bolts. At the four side portions 13, 13, 13, 13, as shown in FIGS. 2 and 3, the two front and rear support plates 14, 14 are attached to the end of the cross member 11 in a T shape with the end sandwiched therebetween. Support plate 1
An end portion of the vertical member 12 is rotatably supported by a pin 15 provided between Nos. 4 and 14. Pin 15 is
It is perpendicular to the front and back of the unit basket 10.

The side portion 13 located at the upper right when viewed from the front,
A plurality of diagonal members 16 extending in the diagonal direction are mounted at equal intervals between the side portion 13 located at the lower left. Similarly, a plurality of diagonal members 16 extending in the diagonal direction are mounted at equal intervals between the side portion 13 located on the lower right side and the side portion 13 located on the upper left side.

As shown in FIG. 4, the diagonal member 16 has a detachable structure similar to that of a "straight brace" used for scaffolding.
On the pin 17 protruding from the front or back of the end of 2
The unit cage 10 is mounted by fitting the round holes provided at the end portions of 6 together. A rotatable claw 18 is attached to the tip of the pin 17 to prevent the pin 17 from coming off.

The horizontal members 11 and the vertical members 12 are square pipes here, but may be square rods, round rods, or round pipes. Also for the diagonal member 16, a round pipe is used here, but a round bar, a square bar, or a square pipe can be used.

As these materials, steel, aluminum, titanium, and other metals capable of being used in terms of strength are used, and those having insufficient corrosion resistance are preferably subjected to surface treatment such as plating.

Next, the function and use of the cage-shaped reef of the first embodiment will be described.

In each unit basket 10, the horizontal members 11 and the vertical members 12 are removed from the front surface and the rear surface, and the four side portions 13, 13, 13, located at the four corners when viewed from the front surface.
In 13, the end of the vertical member 12 is rotatably connected to the end of the horizontal member 11 by a pin 15 that is perpendicular to the front and back surfaces to form a parallel ring, so that if the diagonal member 16 is removed, Both upper and lower surfaces are horizontal and both end surfaces fall to one side,
It transforms into a plane. And the unit baskets 10 and 1 of each stage
By alternately laying 0 ... in the opposite direction, the unit basket 1
0, 10 ... are overlapped and folded thinly.

When using this as a cage-shaped reef,
As shown in FIG. 5, the upper surface of the unit basket 10 located at the uppermost stage is pulled up by a crane or the like. By this pulling up, first, the uppermost unit basket 10 is raised. When the uppermost unit basket 10 becomes a cube, the lifting is temporarily stopped, and the diagonal member 16 is attached to the unit basket 10. As a result, the assembly of the uppermost unit basket 10 is completed. When the assembly of the uppermost unit basket 10 is completed, the pulling up is restarted. As a result, the second-stage unit basket 10 rises up, and when the unit basket 10 becomes a cube, the pulling up is temporarily stopped and the diagonal member 16 is attached to the unit basket 10.

In this way, the unit cages 10, 10 ... Of the respective layers that are stacked and folded are sequentially raised from the top to form a cube, and the diagonal members 16 are sequentially attached to the raised unit cages 10, thereby forming a cage-shaped reef. Is completed. Since the assembled unit baskets 10 are sequentially lifted upward, the diagonal members 16 can always be attached easily and safely at a low place.

Assembling can be done either on land or on the sea, but the folded cage-shaped fish reef can be laid on the pontoon and hoisted on the pontoon, and then the hoisted reef can be further hung up and submerged in the sea. This will make the construction especially efficient. That is, this cage-shaped reef can be easily and safely assembled on a ship, and the assembled reef can be directly laid on the seabed.

FIG. 6 shows a second embodiment of the present invention. The cage-shaped reef according to the second embodiment is formed by connecting the unit cages 10 not only in the vertical direction but also in the horizontal direction. In the connecting portion of the adjacent left and right unit baskets 10, the horizontal member 11 and the vertical member 12 that form the side surface are shared.

By connecting the unit cages 10 in both vertical and horizontal directions, a larger cage-shaped reef can be constructed. Further, even in such a large-sized cage-shaped reef, the unit cages 10 in each row can be collectively pulled up, and the assembly can be easily performed by raising and mounting the diagonal members.

Although the unit tube 10 is a cube in the two embodiments described above, it goes without saying that it may be a rectangular parallelepiped.

At the connecting portion between the adjacent unit baskets 10 and 10, the horizontal members 11 and the horizontal members 11 and the vertical members 12 are shared, but the horizontal members 11 and the horizontal members 11 and the vertical members 12 are not shared. The unit basket 10 may be connected to the unit basket 10.

[0027]

As described above, the folding cage-type fish reef of the present invention can be thinly folded by stacking the unit cages connected in the vertical direction, and thus the transportation cost is low. Since each unit basket can be assembled by pulling up and mounting the diagonal member, the assembly is very easy. Since the assembly work can be performed at a low place, no scaffold is required. Therefore, even bulky basket-shaped reefs can be transported at low cost and can be assembled economically in a short time without using scaffolds. Moreover, since work at a high place is unnecessary, assembly work is safe. Therefore, it is possible to perform efficient construction such as assembling on board a ship, and then submerging the assembled fish reef as it is on the seabed.
