Description

【0001】
【発明の属する技術分野】
本発明は、コンクリート製構築ブロック(護岸ブロックを含む)及びこれを用いた擁壁に関する。
【0002】
【従来の技術】
従来の擁壁として、本願出願人は、各ブロックの胴体の後面から補強棒の後端を突出させ、各後端同志を互いに直交する連結棒で連結し、その後、互いの隙間にコンクリートを充填凝固して形成する技術を、特開平5ー148855号で開示した。
【0003】
【発明が解決しようとする課題】
しかし、上記従来技術においては、各ブロックの胴体の後面から後ろへ伸びた補強棒の後端同志を連結棒で連結する作業は、各ブロックの製品誤差やブロックの積上げ誤差により、隣合う補強棒の位置ズレが一定値を越えると、極めて難しくなる欠点があった。また、各ブロックは胴体の高さが大きくて重く、運搬や施工作業がし難い欠点もあった。
【0004】
そこで、本発明は、積上げられた構築ブロックの補強棒の後端同志を連結する作業が、各ブロックの製品誤差やブロックの積上げ誤差により、隣合う補強棒の位置ズレが一定値を越えても、極めて行い易く、また、胴体の高さが小さくて軽く、運搬や施工作業がし易い構築ブロック及び擁壁の提供を目的とする。
【0005】
【課題を解決するための手段】
本発明による課題解決手段では、構築ブロックを多角形の前面体と、該前面体の後部に形成された胴体とを具えた構造とし、その胴体に、補強棒の前部を埋設する。補強棒の後部を胴体の後面から突出させて、その後部に連結片を直交状態で固着する。
【0006】
多数の構築ブロックを上下左右に積層して、その連結片同士を針金にて連結し、各構築ブロックの胴体間にモルタルや混練セメントを充填凝固して擁壁を形成する。
【0007】
【発明の実施の形態】
以下、本発明の実施例を説明する。まず、図1および図2により第実施例を説明すると、このブロックBは、正六角形からなる前面体1と、該前面体1の後部に後方が狭くなるように形成された角錐台形の胴体2と、前面体1の上下に対向する上下各一個の接辺3から胴体2の後端まで水平に形成された接縁4を有する接突起5とを具え、胴体2の中央に両端が突出する鉄筋製第一突出棒18及び第二突出棒19が埋設され、これら第一突出棒18と第二突出棒19は互いに直交され、前記接突起5の接縁4の一部に凹部4aが形成されている。また、前記胴体2の内部には内部横棒とこれと針金で固定された一本ないし三本の鉄筋製補強棒10の前部が埋設され、前記補強棒10の後部は胴体の後面から突出されるとともに、その後端に鉄筋製連結片11Bが直交溶接され、その両端に短い端片11aが直交溶接され、これら一対の端片11a間の長さは、前面体1の一対の接辺3間の距離と同一とされている。
【0008】
そして、多数の構築ブロックBは上下左右に積層して行き、同軸を共有する第一突出棒18同志を鉄筋製第一短棒(図示せず)を介してまたは介さずに直接連結し、第二突出棒19同志を鉄筋製第二短棒20と針金で連結し、補強棒10の連結片11Bの端片11a同志を針金で連結し、各構築ブロックBの胴体2間にモルタル、セメントや栗石を充填凝固して擁壁を形成する。また、積上げられた構築ブロックBの補強棒10の後端の連結片11B同士は一定の長さの端片11aを有しているので、各ブロックの製品誤差やブロックの積上げ誤差により、隣合う補強棒10の位置ズレが一定値を越えても、端片11aの長さの範囲内であれば、全く支障がなく、連結片同士の連結作業は極めて行い易くなる。
【0009】
なお、一対の端片11a間の長さは、ブロックや擁壁の構造により、前面体1の対角線の長さと同一とされる場合、または前面体1の一辺の長さと同一とされる場合(図参照)もある。
【0010】
次に、第実施例のブロックBを図3および図4で説明すると、このブロックBは、正六角形からなる多角形の前面体1と、該前面体1の後部に後方が狭くなるように形成された角錐台(または円錐台)形で高さが小さい胴体2と、前記前面体1の接辺3から胴体2の後縁まで水平に形成された接縁4を有する接突起5とを具えている。そして、接突起5は接縁4を頂点とする断面円弧形に形成されている。
【0011】
前記胴体2の中央に鉄パイプ製第一筒6及び第二筒7が埋設され、これら第一筒6と第二筒7は互いに直交され、これらの直径は後記の連結棒の二本の合計より少し大きく設定されている。なお、図示しないが第一筒6と第二筒7が別体で前後方向にずれるように交差してもよい。
【0012】
このブロックBにおいては、正六角形からなる前面体1の後側の胴体2の内部に内部横棒とこれと針金で固定された一本の鉄筋製補強棒10の前部が埋設され、前記補強棒10の後部は胴体2の後面から突出されるとともに、その中間部に鉄筋製連結片11Cが直交溶接され、その両端に短い端片11aが直交溶接され、これら一対の端片間の長さは、前面体1の対角線の長さと一辺の長さの合計とされることにより相当長くされている。前記補強棒10の後端部10aはコンクリート壁との結合をよくするために突出されている。
【0013】
そして、多数の構築ブロックBは上下左右に積層して行き、同軸を共有する第一筒6同志を鉄筋(またはプラスチック棒)製第一前連結棒で、第二筒7同志を第二前連結棒で貫通し、補強棒10の連結片11Cの端片11a同志を針金で連結し、第一筒6、第二筒7と第一前連結棒、第二前連結棒との隙間にモルタルをバイブレーターで振動して充填凝固し、各構築ブロックBの胴体2間にモルタル、セメントや栗石を充填凝固して擁壁を形成する。
【0014】
上記においては、積上げられた構築ブロックBの連結片11B同士は一定の長さの端片11aを有しているので、各ブロックの製品誤差やブロックの積上げ誤差により、隣合う補強棒10の位置ズレが一定値を越えても、端片11aの長さの範囲内であれば、全く支障がなく、連結片同士の連結作業は極めて行い易くなる。また、接突起5は接縁4を頂点とする断面円弧形に形成されているので、各ブロックBは接縁4同志の線接触となり、面接触でないので、接縁4のすぐ際までモルタル及びセメントが浸入し、強度が増し、水漏れが防止され、風化しにくくなり、製造誤差を吸収しやすく細工がしやすくなる。
【0015】
次に、第実施例のブロックBを図5および図6で説明すると、正方形の前面体1と、該前面体1の後部の胴体2と、前面体1の上下に対向する一対の接辺3A,3Bの交点から胴体2の後端まで水平に形成された接縁4を有する接突起5とを具えている。また、前記胴体2の内部に内部横棒とこれと針金で固定された二本の鉄筋製補強棒10の前部が埋設され、前記補強棒10の後部は胴体の後面から突出されるとともに、その後端に鉄筋製の十字形連結片11Bが溶接され、その両端に短い端片11aが直交溶接され、これら一対の端片11a間の長さは、前面体1の対角線の長さと同一にされている。その他の構成及び作用は、前記第実施例と同様である。
【0016】
は第実施例であり、これは、長方形の前面体1を含む胴体2の高さHが12〜15cmと小さく軽量化され、かつ、前記胴体2の内部に横棒には針金で固定された四本の鉄筋製補強棒10の前部が約10cm埋設され、これら補強棒10の後部は胴体2の後面から10〜25cmだけ突出されるとともに後端には鉄筋製連結片11E,11Fが直交溶接され、各連結片の先端には短い端片11aが溶接される。なお、前記長連結棒11Eの一対の端片11a間の長さと、短連結棒11Fの端片11a間の長さは、それぞれ前記前面体1の長辺と短辺の長さと同一にされている。その他の構成及び作用は、前記第実施例と同様である。
【0017】
なお、本発明は、上記実施例に限定されるものではなく、本発明の範囲内で上記実施例に多くの修正および変更を加え得ることは勿論である。
【0018】
【発明の効果】
以上の説明から明らかな通り、本発明は、多角形の前面体と、該前面体の後部に形成された胴体と、前記胴体の内部に前部が埋設された補強棒と、前記胴体の後面から突出された補強棒の後部に直交形成された連結片とを具えてなる構築ブロックである。
【0019】
したがって、本発明では、積上げられた構築ブロックの連結片同士を針金で連結し、各構築ブロックの胴体間にモルタルや混練セメントを充填凝固して擁壁を形成することができる。また、胴体の高さを小さく軽くできるので、運搬や施工作業がし易い構築ブロック及び擁壁を提供できる優れた効果がある。

Filling and solidifying the rubble stone to form a retaining wall. Moreover, since the connecting pieces 11B at the rear end of the reinforcing bars 10 of the stacked building blocks B have end pieces 11a of a fixed length, they are adjacent to each other due to a product error of each block or a stacking error of the blocks. Even if the positional deviation of the reinforcing rod 10 exceeds a certain value, if the positional deviation is within the range of the length of the end piece 11a, there is no problem at all and the connecting work between the connecting pieces becomes extremely easy.
[0009]
Note that the length between the pair of end pieces 11a is the same as the length of the diagonal line of the front body 1 or the length of one side of the front body 1 due to the structure of the block or the retaining wall ( FIG. 7 ).
[0010]
Next, the block B of the second embodiment will be described with reference to FIGS. 3 and 4. The block B is a polygonal front body 1 composed of a regular hexagon and a rear portion of the front body 1 is narrowed at the rear.
