本発明は、盛土、切上等の崩落を防止する土止擁壁の構
築に用いるコンクリート部材に関する。DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a concrete member used for constructing a retaining wall for preventing the collapse of embankments, cut-overs, etc.
（従来技術）
柔構造に属するいわゆるブロック積みによる擁壁のよう
な土止擁壁としては、コンクリート部材だけを用いるも
の、コンクリート部材とアンカーバーとを用いるもの等
種々提案されている。また、コンクリート部材の形状、
アンカーＩく−の形状、積み上げた土止擁壁の構造シ種
々提案されている。(Prior Art) Various types of earth retaining walls such as so-called block-laid retaining walls belonging to flexible structures have been proposed, such as those using only concrete members and those using concrete members and anchor bars. In addition, the shape of the concrete member,
Various shapes of anchors and structures of stacked retaining walls have been proposed.
しかし、従来のコンクリート部材を用いた土止擁壁は、
隣接するコンクリート部材が相互に連結されていないた

地の不揃いな開き、上下１前後方向への目違いが日時の
経過と共に発生し、美観を損ない、不安感を与えている
。また、従来のコンクリート部材を用いた土止擁壁は、
その基底部に不当な地盤沈下が発生すると、コンクリー
ト部材相互の垂直方向へのずれが前記地盤沈下をした箇
所の近傍に集中して発生するため、その箇所が欠陥箇所
となり、土止擁壁の品質が低下する。However, retaining walls using conventional concrete members,
Because adjacent concrete members are not connected to each other, the embankment behind the retaining wall may sink unduly or be displaced toward the retaining wall, causing concrete members to move and cause damage to the retaining wall. As a result, irregular openings of joints in concrete members and misalignment in the vertical and longitudinal directions occur over time, spoiling the aesthetic appearance and giving a sense of insecurity. In addition, retaining walls using conventional concrete members,
If unreasonable ground subsidence occurs at the base, the vertical displacement of concrete members will be concentrated in the vicinity of the site where the ground has subsided, resulting in a defective location and the failure of the retaining wall. Quality deteriorates.
すなわち、従来の±（ト擁壁は、長期にわたる地盤、盛
土の不当沈下、あるいは急激におとずれる地震による地
盤盛土の変位等に対し、コンクリート部材相互の位置関
係を積極的に維持する手段を講じていなかったため、上
記のような種々の弊害を生じていた。In other words, conventional retaining walls take measures to actively maintain the mutual positional relationship of concrete members against unreasonable subsidence of the ground or embankment over a long period of time, or displacement of the ground embankment due to sudden earthquakes. As a result, various disadvantages such as those mentioned above were caused.
さらに、従来のコンクリート部材は、構造が複雑である
と、機械的強度が大きい反面、製造が面倒であるため高
価であり、これとは逆に構造が簡単であると、製造が容
易であり、廉価である反面、機械的強度が小さいため安
全性に欠ける欠点がある。Furthermore, when conventional concrete members have a complicated structure, they have high mechanical strength but are difficult to manufacture and are therefore expensive; on the other hand, when the structure is simple, they are easy to manufacture. Although it is inexpensive, it has the disadvantage of lacking safety due to its low mechanical strength.
（発明の目的）
本発明は、隣接するコンクリート部材を相互に容易に連
