<Prior art and its problems> The inventor of the present invention previously devised a concrete block formed into a hemispherical hollow shape with a large number of through holes in the hemisphere (see Japanese Utility Model Publication No. 10654/1973), and used it to dissipate waves. It has been used as a water block, a foot protection block, and a fish reef block. This block was formed into a hemispherical hollow shape and a through hole was bored in the hemispherical portion, so that it was confirmed that it is considerably more useful as the above-mentioned various blocks than the conventional blocks of the same type. However, in the conventional example described above, since it is formed into a hemispherical hollow, its overall shape is that of a hollow sphere divided into two halves, so there is a large opening at the bottom. will be formed. When this was installed on the ocean floor or riverbed, it was discovered that the earth and sand on the bottom of the hemisphere eroded over time. That is, the block body sinks to the sea floor or river bed over time. As the earth and sand at the bottom eroded, each block tilted, causing problems such as the blocks becoming misaligned and the stacked blocks collapsing.

<Means for Solving the Problems> Therefore, in order to solve the above-mentioned problems, the construction block according to this invention has a bottom plate disposed in the bottom opening of the porous hemispherical hollow block, and the construction block according to the invention The bottom plate prevents erosion of earth and sand at the bottom of the block and stabilizes the block, and the hemispherical hole has a wave-dissipating function. It was also designed to serve as a fish nest (nest for fish).

<Example> Next, an example of the construction block according to the present invention will be described based on the drawings. Reference numeral 1 is a hemispherical hollow block with a hollow interior, and an opening at the bottom of the hemispherical hollow block 1 A bottom plate 2 is provided in the section to close this opening. Reference numeral 3 designates a through hole bored in the hemispherical portion 4 of the hemispherical hollow block 1. A desired number of through holes 3 may be provided at desired positions in the hemispherical portion 4. A hexagonal joint 5 is formed at the bottom of the hemispherical part 4.

<Function> This construction block is installed at a desired location on the coast or riverbank, and the blocks can be installed continuously using the joints 5. Since the bottom plate 2 is provided, there is no need for special preparation work on the installation surface during installation, so the installation work is very simple, as it is only necessary to line them up. In addition, the bottom plate 2
Since the installation area increases and the load per unit area of the installation surface decreases, it may be impossible to install with conventional wave-dissipating blocks or foot protection blocks, or special preparations may be required. It can be installed as is even on soft ground, so it has a wide range of uses. Similar to the block previously devised by the present inventor, the through hole 3 bored in the hemispherical portion 4 has a wave-dissipating effect, and since the inside is hollow, it also functions as a fish nest. That's what happens.

<Effects of the invention> As described above, according to the construction block according to the invention, a bottom plate is disposed at the bottom opening of the porous hemispherical hollow block, and the opening is closed. There are wave-dissipating blocks, foot protection blocks, seawall blocks, fish nest blocks,
In addition to having all the functions as a block for fish reefs, the bottom plate prevents the erosion of earth and sand at the bottom of the block, allowing the block to function effectively for a long period of time without losing its alignment. The effects are significant.
