Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is configured so that formation of a cross-shaped block having an arbitrary number of stages and rows can be achieved extremely easily by using the required number of each of Ξ types of constituent members. This invention relates to a cross-shaped assembly block, and is characterized in that it is designed to be optimally used as a so-called fish reef block installed underwater to collect fish.

In recent years, concrete fish reefs have been sunk into the sea to cultivate shellfish such as abalone and scallops, to tie seed ropes such as cups and wakame, and to collect or cultivate various types of fish. .

However, this type of native fish reef has an independent structure, such as a hexahedron of 1.2 to 1.5 cubic meters with windows formed on each side, and is completed on the ground. A system was adopted in which the transformed fish reefs were transported by boat and dropped into the sea, where they were sunk. However, with something like this, for example, when multiple fish are dropped, each reef
Not only are they scattered and their contact postures extremely irregular, but the reefs themselves are not very large, so they are often buried in the sand on the sea floor, washed away by ocean currents, or dragged by bottom trawlers. This inevitably led to problems such as:

The present invention provides that, when used as a fish reef, a parallel-shaped fish reef is formed in multiple stages, which is completely different from the above-mentioned conventional fish reefs, and unlike conventional fish reefs, it can be assembled underwater. This makes it possible to form extremely large-scale fish reefs as a type of underwater structure, such as the formation of fish farms, and thus solves the problems in the conventional system as described above. It is characterized by the fact that it has been designed to

Hereinafter, the configuration of the present invention will be explained in detail with reference to the drawings.

It was created so that it would be achieved.

The girder block A shown in Figures 3 and 4 has the required dimensions (for example, length 200mm, width 1390mm, thickness 1

Reference numerals 7 and 7 denote girder block restraining portions formed on the lower surface of the base plate 4 in a direction orthogonal to the receiving portions 6, 6, and girder block restraining portions formed on the upper surface of the end portions of the girder block A at required locations. Locking protrusions 7a, 7a are respectively formed to be inserted into the above-mentioned engagement grooves 2.

The receiving portions 6, 6 and the restraining portions 7, 7 for the girder block A are each provided with a width that allows the girder block A to be engaged with the structure. The grounding leg block C shown in FIGS. 10 to 13 is constructed as follows.

Reference numeral 8 denotes a square substrate portion, the lower surface of which is formed into a flat shape.

Reference numerals 9 and 9 denote connection support pieces that are erected at the center of the upper surface of the base plate 8 so as to face each other with a predetermined distance S between them. Common holes 9a, 9a are bored.

Locking protrusions 10a, 10a are respectively formed to be inserted into the above-mentioned engagement grooves 2''.

The above-mentioned connecting support pieces 9, 9 and girder block receiving parts 10, 10 have the same form as those provided in the above-mentioned connecting block B, and after all, the grounding leg block C is connected to the board. It has the same shape and dimensions as the above-mentioned connecting block B, except that the lower surface of the portion 8 is a flat surface for grounding. Now, the locking protrusions 6a, 6a and 7a, 7 in the above-mentioned connecting block B
a1 and the locking protrusion 10 on the grounding leg block C
a, 10a, but these are to be combined with the engagement grooves 2, 2'' in the girder block A to stabilize the connection of the girder block A. There is no problem even if the engagement is reversed, and the present invention may be implemented in such a form.The present invention has the above configuration, and the following describes how to assemble the block of the present invention. Explain the procedure.

First, as shown in FIG. 14, if the upper connecting block B and the lower connecting block B are positioned 90 degrees apart, the girder block receiving parts 6, 6 and the girder block restraining part 7 of both , 7 are placed in an opposing state.

Therefore, the end of the girder block A is held here, and the connecting protrusion piece 5 of the upper connecting block B is held here.
The bolts are inserted into the spacing S between the connecting support pieces 3, 3 in the lower connecting block B, and then inserted into the matching bolt insertion holes 3a, 5a, 3a. When tightened, the locking protrusions 6a and 7a of the receiving part 6 and the restraining part 7 engage in the engaging grooves 2 and 2'' formed at the ends of the girder block A, and both A firm connection is maintained based on the clamping by parts 6 and 7 (the first
(See Figure 5). At this time, the girder block receiving parts 6, 6 in the upper connecting block B are oriented in a direction perpendicular to the girder block A to be connected as described above, so they are shifted 90 degrees upward. If a new connecting block is attached in the same manner as described above, the new girder block will be connected in a direction perpendicular to the girder block A. By repeating such operations one after another, the required number of girder blocks are assembled in the shape of a parallel girder as shown in FIGS. 1 and 2.

The grounding leg block C is installed at the lowest position of the connecting block B as shown in Figure 2, and is intended to stabilize the grounding of the assembled cross-shaped block. It is.

According to the present invention described in detail above, when this reef is used as a fish reef submerged in the sea, unlike conventional hexahedrons and other independent units, it can be formed into the required shape according to the purpose, that is, the required multi-stage, multi-row structure. Because it can be assembled into any shape, such as a well-shaped cross-shaped block or a rectangular frame that divides a given sea area into shelves to establish a fish farm, the scale of aquaculture of fish based on the formation of fish reefs can be increased. It will be significantly expanded and enable completely new research and development. Further, since the present invention is configured to be assembled using three types of girder blocks A, connecting blocks B, and leg blocks C, manufacturing, assembly, and management operations are significantly simplified based on the small number of constituent members. Manufacturing costs will also be significantly reduced.

Furthermore, the present invention aims at fixing the girder block A by interlocking the connecting blocks B by shifting them by 90 degrees and clamping them together based on the connection with the leg block C. Blocks B are connected to each other through their respective insertion holes 3.
Since the structure is such that it is sufficient to insert and tighten the bolts from the lateral direction to a, 5a, and 9a, the assembly and fixing work can be performed one step at a time from the bottom, which simplifies the work. For example, the difficulty of assembly work that would occur if bolts were used to vertically pass through each block to fix the connection all at once from the vertical direction was completely eliminated. At the same time, the present invention can be very easily assembled underwater.

Furthermore, since the present invention employs such a fastening means,
When installed underwater, if distortion of the seabed ground or pressing force due to ocean currents is applied, the bolts of the connection part act like a pivot to absorb this, that is, for example, horizontal Even if the girder blocks are assembled in a shape, the installation angle will naturally change in response to the above distortion etc.
(Because the connecting block itself can quickly rotate around the bolt as a pivot), therefore, if the entire assembled block is made completely rigid (for example, by using bolts that connect all of them in the vertical direction as described above) This will effectively avoid the occurrence of accidents such as collapse due to the inability to respond quickly to changes in the seabed ground that occur. As described above, the present invention has a simple structure and exhibits excellent functions and effects, so it is ideal not only for use as a fish reef but also as a retaining wall block for use on land.
