る。Problems that the invention aims to solve In the above invention, when placed in the deep sea as a fish reef, when it is placed vertically on the seabed, the hollow part faces upward, making it difficult for schools of fish to settle due to water pressure. The problem is that it is unstable and obstructs the growth of fish by blocking ocean currents.
そこで、この考案は之等の欠点を除くために、
コンクリートブロツクより成る胴体の長手方向に
空洞部を貫通すると共に該胴体を海底に定置させ
るよう脚柱を設けて底面積を広くして魚群の安住
を図ることを目的としている。 Therefore, in order to eliminate these drawbacks, this idea was created to
The object is to extend the bottom area of the body by penetrating the hollow part in the longitudinal direction of the body made of concrete blocks, and to provide a pillar for fixing the body on the seabed, thereby widening the bottom area and making it possible for schools of fish to live there safely.
問題点を解決するための手段
上記目的を達成するための本考案の構成を図面
について説明すると、本考案は、胴体の長手方向
の中央部に貫通口を貫通し、該胴体の背面部より
連結腕を突出し、その端部に脚柱を一体的に取り
つけ該脚柱の下端面と胴体の底面が一直線上にあ
るように構成したものである。Means for Solving the Problems The structure of the present invention for achieving the above object will be explained with reference to the drawings.The present invention has a through hole in the longitudinal center of the body, and is connected from the back side of the body. The arm is protruded, and a leg post is integrally attached to the end of the arm so that the lower end surface of the leg leg and the bottom surface of the body are in a straight line.
作 用
そして、本考案は前記手段により海中に投入し
た場合、海底において、常に胴体の底面と脚柱の
下端面とが一直線上にあると共に底面積が広いの
で、安定した状態で魚礁の機能作用を有するもの
である。When the present invention is put into the sea by the above method, the bottom surface of the body and the lower end surface of the pedestal are always in a straight line on the seabed, and the bottom surface is wide, so that the fish reef functions in a stable state. It has the following.
実施例
以下図面に示した実施例に基いて本考案を説明
する。Embodiments The present invention will be described below based on embodiments shown in the drawings.
第１図及び第２図は、本考案の一実施例を示す

か許り隆起し、下方部は著しく垂下させた脚柱４
を一体的に構成することにより、該脚柱４の下端
面と胴体一の底面とが一直線上の位置にあるよう
形成したものである。 Figures 1 and 2 show a concrete reef block showing an embodiment of the present invention. In this drawing, a body 1 is formed into a substantially O-shape with a bottom surface, and a through hole 2 passes through the body in the longitudinal direction. Reference numeral 3 is a connecting arm, which protrudes continuously rearward from the back surface of the body 1, and has a pillar 4 whose upper part is slightly raised at the end and whose lower part is significantly drooped.
By integrally configuring the pedestal 4, the lower end surface of the pedestal 4 and the bottom surface of the body 1 are formed in a straight line.
従つて、海上より海中に投下した場合に脚柱の

ある。説明を簡単にするために第１図および第２
図と同様の作用をなす部分は同一符号を以つて説
明する。 Therefore, when dropped into the sea from the sea, the pillars are arranged so that the center of gravity is low and the base area is wide, so that it can be stably placed on the seabed. 3 and 4 show other embodiments of the present invention. Figures 1 and 2 are used to simplify the explanation.
Parts having the same functions as those in the figures will be described using the same reference numerals.
本実施例では胴体１の前側面にその長手方向に
従つて開口部５を構成して魚群がはいり易いよう

ことができて魚礁として実益多きものである。Effects of the invention As explained above, in this invention, the through hole 2 is passed through the longitudinal center of the body 1, and the leg column 4 is integrally formed at the end of the connecting arm 3 that is continuous from the back side of the body. The upper part of the pillar 4 is slightly raised,
The lower part hangs down for a long time and is formed so that its lower end is in a straight line with the bottom of the fuselage, so it always maintains a horizontal state even after being thrown into the ocean floor, and at the same time has a low center of gravity and a wide base area. It is very useful as a fish reef because it can maintain a stable state.
