< Topic >The center section of the rope which hangs the group of shellfishes in the cultivation device of the bivalvia in the underwater, at sea level the horizontal attachment component which stopping is done, the rope moving up and down by significance of the shellfish and power of the water flow which works in the shellfish, the attachment component with wear deficiency doing, making strength weak, the fact that it falls the rope and the shellfish to the seabed is prevented, and the person drives and withstands and, offers the attachment component for cultivation which possesses the high kind of strength which can.SolutionsBeing the horizontal FRP make attachment component on the of the rope R which is constructed in the beam component of sea level of the gate die standards group which stand facilities is done in the seabed, it concatenated with the transverse member 2b which provides the height 40mm board thickness 5mm longitudinal member 2a in 3 strings in 80mm pitch, provided small projection 2a1,2b1 in the surface of the longitudinal member and the transverse member, these formed just with FRP.< Choice figure >Drawing 4【課題】貝類の養殖装置における複数の貝を海中で吊すロープの中央部を、海面上で掛止する水平な保持部材が、貝の重み及び貝に働く水流の力でロープが上下に動いても、保持部材が摩耗で欠損して強度を弱くしてロープと貝を海底に落下させるのを防ぎ、又人がのっても耐えうるような高い強度を有する養殖用保持部材を提供する。【解決手段】海底に立設した門型支柱群の海面上の梁部材に架設されるロープRの吊上用の水平なFRP製保持部材であって、3列の高さ40mm板厚5mm縦部材2aを80mmピッチに設けた横部材2bで連結し、縦部材及び横部材の上面に小突起2a1,2b1を設け、これらをFRPで一体成型した。【選択図】図4
