明 細 書  Specification
発明の名称 コンクリート空積みブロックと基礎盤 -  Title of invention Empty concrete block and foundation board-
技術分野 Technical field
本発明は、 河川の護岸等に用いられるコンクリ一ト製の空積みプロックとこれ を支持する基礎盤に係り、 例えば河川の蛇行に応じて直線状または曲線状のいず れに構築した場合でも、 各プロックの前後にずれが生じないようにしたコンクリ 一ト空積みプロックと基礎盤に関する。 背景技術  The present invention relates to a concrete empty loading block used for revetment of rivers and a foundation board supporting the same, for example, even if the block is constructed in a linear or curved shape according to the meandering of the river. The present invention relates to a concrete empty-loading block and a base plate which are prevented from shifting before and after each block. Background art
河川の護岸等に用いる擁壁を構築する施工法としては、 コンクリートブロック を積み重ねることによつて高さを確保するようにしたプロック積み工法が知られ ている。 この工法には、 主として、 積み重ねた各プロックの中空部にコンクリー トを充填することによって各プロックを互いに固定するようにしたコンクリート 充填工法と、 各プロックを互いに嚙み合わせるだけで固定するようにした空積み 工法とがある。  As a construction method for constructing retaining walls used for revetment of rivers, a block construction method is known in which concrete blocks are stacked to secure a height. This method mainly consists of a concrete filling method in which each block is fixed to each other by filling concrete into the hollow portion of each stacked block, and a method in which each block is fixed only by interlocking with each other. There is an empty loading method.
なかでも空積み工法は、 これに用いられる空積みブロックの中空部に充填した 土等に植物を根付かせたり、 石等で空間を作ることにより魚を生息させることが 可能であり、 近年になって推奨されている環境保全型プロックに好適するもので める。  Above all, the empty stacking method allows fish to inhabit by rooting plants in soil or the like filled in the hollow part of the empty stack block used for this purpose, or by creating a space with stones, etc. Suitable for the environmentally friendly block recommended by
このようなコンクリートプロックの空積み工法は、 複数段のプロックを積み重 ねる際に、 岸側に傾きを有する勾配状に積み重ねることによって土圧に耐える構 造にすると共に、 上下の各列で互いに千鳥状に積み重ねることによって横方向の 連結を保つようにしているが、 積み重ねた基礎盤と各ブロック間に前後のずれが 生じない構造が必要となる。 この前後のずれを防止するための構造は、 基礎盤とプロックとの接合部及び各 段のブロック同士の接合部を凹凸形状で嚙み合わせる構造によって実現される。 即ち、 この嚙み合わせ構造は、第 1 5図 (a)及び (b)に示すように、基礎盤 3 0の 上部の前後端に沿って凸部 3 1、 3 1が形成され、 これらの前後の凸部 3 1、 3 1間の凹部にブロック （その底部を斜線で示す） 3 2、 3 2…を千鳥状に嚙み合 わせるものである。 Such a method of stacking concrete blocks is based on the method of stacking multiple blocks in a pile with a slope with a slope on the shore side to withstand the earth pressure, and also make each other the upper and lower rows with each other. The staggered stacking keeps the connection in the horizontal direction, but it is necessary to have a structure in which there is no back and forth displacement between the stacked foundation boards and each block. The structure for preventing the back-and-forth displacement is realized by a structure in which the joints between the base plate and the block and the joints between the blocks at each stage are combined in an uneven shape. That is, in this mating structure, as shown in FIGS. 15 (a) and (b), convex portions 31 and 31 are formed along the front and rear ends of the upper portion of the foundation board 30. Blocks (the bottoms of which are indicated by oblique lines) 32, 32, ... are staggered in the recesses between the front and rear projections 31, 31.
ところで、 上記の嚙み合わせ構造を用いて、 蛇行する川岸等に空積み擁壁を構 築するには、 第 1 5図 (a)に示すように、 基礎盤 3 0、 3 0…の夫々の前後の凸部 3 1 , 3 1間の凹部にプロック 3 2、 3 2…を曲線状に配列して嚙み合わせるた めの遊び （隙間） 3 3が必要となる。  By the way, in order to construct an empty retaining wall on a meandering riverbank, etc. by using the above-mentioned combination structure, as shown in Fig. 15 (a), each of the baseboards 30, 30, ... A clearance (gap) 33 is required to arrange the blocks 32, 32, ... in a curved shape and engage them in the concave portion between the convex portions 31, 31 in front and behind.
ところが、 第 1 5図 (b)に示すように、 基礎盤 3 0、 3 0…を直線状に配列して、 これらの基礎盤 3 0、 3 0 ···の凸部 3 1、 3 1間の凹部にプロック 3 2、 3 2 ··· を千鳥状に嚙み合せて配列すると、 各プロック 3 2 .. 3 2…が遊び 3 3の分だけ 前後へ移動する余地を有することとなり、 施工中や施工後において、 各ブロック 3 2、 3 2…に前後のずれが生じたり、 法面に狂いが生じたりする。  However, as shown in Fig. 15 (b), the base boards 30, 30, ... are arranged in a straight line, and the projections 31, 31, ... of these base boards 30, 30, ... When the blocks 32, 32, ... are arranged in a zigzag pattern in the recess between them, each block 32, .. 32, ... has room to move back and forth by the amount of play 33, During and after construction, blocks 3 2, 3 2… will shift back and forth, and slopes will be out of order.
また、 岸側に傾斜した状態で曲線部を施工する際、 各ブロックを積み上げてい <に従って曲率半径が変化するため、 各ブロックに横方向のずれが生じる。 とこ ろが、 この横方向のずれに対処する施工が面倒なため、 左右の各ブロック間の前 方をすかしたり、左右の各ブロック間の隙間をそのままの状態にして構築したり、 その隙間を目地コンクリートで詰めたりしていたのが現状である。 このように、 ブロック間の隙間、 特に、 ブロック間の前方に隙間が生じると、 この隙間から岸 側の土等やプロックに充填した土等が洩れ出る原因となる。  In addition, when constructing a curved section with the slope on the shore side, each block is piled up and the radius of curvature changes according to <, so that each block is shifted in the horizontal direction. However, since it is troublesome to work to cope with this lateral displacement, the front between the left and right blocks may be cut off, the gap between the left and right blocks may be left as it is, or the gap may be constructed. At present is filled with joint concrete. Thus, if a gap between the blocks is formed, particularly a gap in front of the block, the soil on the shore or the soil filled in the block may leak from the gap.
本発明は、 上記の問題点を解消するために成されたもので、 コンクリートプロ ックの空積み施工において、 直線施工であっても、 曲線施工であっても、 横方向 に隙間をつくることなく、 前後にずれのない状態で嚙み合わせることができるコ ンクリート空積みプロックと基礎盤を提供することを目的とする 発明の開示 The present invention has been made in order to solve the above-mentioned problems, and it is intended to create a gap in a lateral direction in an empty pile construction of a concrete block regardless of whether it is a straight construction or a curved construction. That can be combined without any back and forth Disclosure of the Invention for the purpose of providing concrete empty loading blocks and foundation boards

以上説明したように、 本発明は、 河川の護岸等に用いる空積み施工用のコンク リ一ト空積みプロックと基礎盤に適するものであり、 各プロックは複数段に千鳥 状に配列され、 各基礎盤はその上に千鳥状に積み重ねた各プロックを支持するよ うに施行する。  INDUSTRIAL APPLICABILITY As described above, the present invention is suitable for a concrete empty-loading block for foundation work and a foundation board used for river bank protection, etc., and the blocks are arranged in a staggered pattern in a plurality of stages. The baseboard will be used to support each block staggered on top of it.
本発明は、 このような千鳥状に積み重ねた各プロックの上部前側の左右と下部 後側の左右に離間された突部がこれに対接する各プロックの上下の縁部を係止す る構造によって、 前後夫々に二点支持による嚙み合わせ構造を構築することがで きるため、 直線施工及び曲線施工のいずれにおいても、 前後にずれの生じない空 積みブロックの施工が可能となる。 According to the present invention, the protruding portions which are separated from each other on the upper front side and the lower rear side of the staggered stacked blocks lock the upper and lower edges of the respective blocks which are in contact therewith. With such a structure, it is possible to construct a mating structure with two-point support at each of the front and rear, and therefore, it is possible to construct an empty stacking block that does not shift forward and backward in both straight construction and curved construction.
また、 直線状または曲線状に敷設された各基礎盤に千鳥状に積み重ねた各プロ ックの下部前側の突縁部が左右に隣接された両側基礎盤の各案内突部に係止され ると共に、 各プロックの底面内の左右に設けられた案内突部が左右に隣接する両 基礎盤の後側の各突縁部に係止されたことによって、 各基礎盤に積み重ねる各ブ ロックにおいても、 前後夫々に二点支持による嚙み合わせ構造を構築することが できる。  In addition, the protruding edge of the lower front side of each of the blocks stacked in a staggered manner on each of the foundation boards laid in a straight or curved shape is locked to each of the guide projections of the both side foundation boards adjacent to the left and right. At the same time, the guide projections provided on the left and right in the bottom surface of each block are locked to the respective protruding edges on the rear side of both base boards adjacent to the left and right, so that the blocks stacked on each base board are also A mating structure with two-point support can be constructed for each of the front and rear.
また、 本発明による空積みブロック及び基礎盤を直線状に配列した場合でも、 内力一ブの曲線状に配列した場合でも、 外力一プの曲線状に配列した場合でも、 各基礎盤間または各プロック間において隣接する側部の前側角部が合致する力 または双方の側部同士が合致することによって内部に充填した土等が洩れ出るこ とがない。  In addition, even when the empty stacking block and the foundation board according to the present invention are arranged in a straight line, when they are arranged in a curved line with an internal force, or when they are arranged in a curved line with an external force, each base board or each Since the front corners of the adjacent sides match between the blocks or the two sides match, no soil or the like filled inside leaks out.
なお、 本発明における各空積みプロック及び各基礎盤は奥行き幅及び横幅共に 同一のものを使用して構築することができる。 ただし、 空積みブロックを配列し た横方向の端部においては調整する必要があるが、 これは全体の非常に僅かな部 分であり、 概ねは同一の空積みプロック及び基礎盤を用いることができるため、 製造及び施工においても、 簡易かつコストの低減を図ることが可能となる。  In addition, each empty loading block and each foundation board in the present invention can be constructed using the same thing in both the width and depth. However, it is necessary to adjust at the horizontal end where the empty blocks are arranged, but this is a very small part of the whole, and it is generally possible to use the same empty loading block and foundation board. Therefore, in manufacturing and construction, it is possible to simplify and reduce costs.
