Description

【０００１】
【発明の属する技術分野】
この発明は、土砂崩れ防止用金網に関し、より特定的には、コンクリートを受け入れて固めることによって斜面の土砂崩れを防止するための土砂崩れ防止用金網に関するものである。
【０００２】
【従来の技術】
山の急斜面などに、土砂崩れを防ぐためのコンクリートが敷設されることがある。図１は、山の斜面にコンクリートを敷設した状態を示している。一般的には、コンクリート３０の強度確保などの目的から、コンクリート３０の表面は、凹部３０ｂと凸部３０ａとを有する凹凸形状とされる。
【０００３】
コンクリート３０を上記のように凹凸形状にするために、コンクリート３０の凸部３０ａの中には、金網が埋設される。
【０００４】
図２は、コンクリート３０中に埋設された金網を示している。図示するように、１対の金網１１０，１１０が所定の間隔で縦横に並ぶように配置されている。１対の金網１１０，１１０の全体構造は、図３に示すような多数の金網ユニット１０を組み合わせて作られる。
【０００５】
図３に示すように、土砂崩れ防止用金網ユニット１０は、第１金網１と、第２金網２と、両金網１，２の間に位置して両金網の間隔を一定に保つネットコネクタ２０と、図４に示す鉄筋３とを備える。第１および第２金網１，２は、典型的にはクリンプ金網である。
【０００６】
図３および図４に示すように、ネットコネクタ２０は、上横棒２１と、下横棒２２と、左縦棒２３と、右縦棒２４とを有する。上下の横棒２１，２２は金属製の棒材であり、その両端が第１および第２金網１，２に連結されている。左右の縦棒２３，２４も金属製の棒材であり、上下の横棒２１，２２に交差するように配置されている。横棒２１，２２と、縦棒２３，２４とは、それらの交差部で溶接されることによって、互いの位置関係が固定される。
【０００７】
図３および図４に示したネットコネクタ２０は、２本の平行な横棒２１，２２と２本の平行な縦棒２３，２４とを備えたものであるが、２本の平行な横棒とそれらに交差する１本の縦棒とから構成されるものもある。
【０００８】
土砂崩れ防止用金網ユニット１０は、図３に示すように、複数のネットコネクタ２０を所定の間隔で配置させている。金網ユニット１０の構造を強固にするために、横棒２１，２２と縦棒２３，２４との交差部に鉄筋３を配置する。鉄筋３は複数のネットコネクタ２０を連結するように、すなわち図４において紙面に対して垂直な方向に延びている。
【０００９】
図４に示した構造では、４本の鉄筋が用いられているが、それらの固定は、次のようにして行う。まず、法面に２本の下鉄筋３を設置する。次に、２本の下鉄筋３の上に図３に示す金網ユニット１０を置く。次に、下鉄筋３を持ち上げて横棒２２と縦棒２３，２４との交差部に位置させ、その位置で鉄筋３と交差部とを細いワイヤ４で巻き付けて固定する。次に、上鉄筋３を横棒２１と縦棒２３，２４との交差部に位置させ、その位置で鉄筋３と交差部とを細いワイヤ４で巻き付けて固定する。
【００１０】
【発明が解決しようとする課題】
従来の土砂崩れ防止用金網ユニット１０においては、細いワイヤ４を用いて鉄筋３を交差部に巻き付けて固定している。図４に示した形状のネットコネクタ２０の場合、１個のネットコネクタ２０に対して４回の巻き付け作業を行わなければならない。金網ユニット１０は、複数のネットコネクタ２０を備えているので、１個の金網ユニット１０に対して鉄筋３の巻き付け作業の回数は非常に多くなる。
【００１１】
また、上記の巻き付け作業は急な斜面上で行うものであるので、巻き付け力が弱いと鉄筋が滑り落ちてしまう危険性がある。そのため、慎重かつ確実な巻き付け作業が要求される。上記のような巻き付け作業は作業者にとって非常に煩雑である。また、多くの作業時間を必要とするので、結果として工期の長期化につながる。
【００１２】
この発明は、上記の課題を解決するためになされたものであり、その目的は、鉄筋の固定作業を簡単にかつ短時間で行うことができるようにした土砂崩れ防止用金網ユニットを提供することである。
【００１３】
【課題を解決するための手段】
この発明に従った土砂崩れ防止用金網ユニットは、第１および第２の金網と、ネットコネクタと、鉄筋と、鉄筋固定プレートとを備える。ネットコネクタは、第１および第２の金網の間に位置して両金網の間隔を一定に保つものであり、両端が第１および第２の金網に連結される横棒と、この横棒に対して交差するように配置され交差部で横棒に固定される１対の縦棒とを有する。鉄筋は、ネットコネクタの横棒と縦棒との交差部に連結された状態で第１および第２の金網の間を延びる。
【００１４】
鉄筋固定プレートは、横棒上に位置し、１対の縦棒を上下に通過させる１対の縦棒受入れ開口と、鉄筋を交差部に向かって弾性的に押し付けて保持する弾性保持部とを有する。この鉄筋固定プレートは、各縦棒受入れ開口を形成する開口縁部を各縦棒に弾性的に係合させている。
【００１５】
上記の構成によれば、簡単な操作で鉄筋固定プレートをネットコネクタに装着でき、かつ鉄筋を鉄筋固定プレートの弾性保持部により簡単に固定保持することができるので、鉄筋の固定作業を簡単かつ短時間で行なうことができるようになる。また、鉄筋固定プレートの１対の縦棒受入れ開口を形成する開口縁部が１対の縦棒に弾性的に係合しているので、鉄筋固定プレートがネットコネクタから外れるのが阻止される。
【００１６】
一つの実施形態では、解放状態にある鉄筋固定プレートの１対の縦棒受入れ開口の間隔は、１対の縦棒の間隔と異なっている。したがって、鉄筋固定プレートをネットコネクタの１対の縦棒に装着する際には、１対の縦棒受入開口の間隔を１対の縦棒の間隔と同じになるように鉄筋固定プレートを弾性的に撓ませる。装着後においては、鉄筋固定プレートは、元の形状に復帰しようとする弾性力を発揮するので、縦棒受入れ開口を形成する開口縁部は縦棒に弾性的に係合する。
【００１７】
縦棒受入れ開口は、例えば、鉄筋固定プレートを貫通する貫通穴である。あるいは、縦棒受入れ開口は、鉄筋固定プレートの長さ方向端縁から内方に向かって切込まれた切込み開口である。また、一つの形態では、縦棒受入れ開口は、鉄筋固定プレートの一部を縦棒の端部側に向かって切起こすことによって形成されており、この切起こし部が縦棒に弾性的に係合している。
【００１８】
この発明に従った鉄筋固定プレートは、ネットコネクタの横棒と１対の縦棒との交差部に鉄筋を固定保持するためのものであり、横棒上に位置するように配置される。この鉄筋固定プレートは、１対の縦棒受入れ開口と、弾性保持部と、弾性係合手段とを備える。１対の縦棒受入れ開口は、１対の縦棒を上下に通過させるものである。弾性保持部は、受け入れた鉄筋を交差部に向かって弾性的に押し付けて保持する。弾性係合手段は、各縦棒受入れ開口を形成する開口縁部を各縦棒に弾性的に係合させる。
【００１９】
一つの実施形態では、弾性係合手段は、１対の縦棒受入れ開口の間隔を１対の縦棒の間隔と異ならせることによって弾性係合力を発揮するものである。また一つの実施形態では、縦棒受入れ開口は、当該鉄筋固定プレートの一部を縦棒の端部側に向かって切起こすことによって形成されており、この切起こし部が弾性係合手段を構成する。
【００２０】
また、一つの実施形態では、弾性保持部は、当該鉄筋固定プレートの両端部を縦棒の端部側に向かって折り曲げることによって形成されている。この場合、弾性保持部は、折り曲げ部の一部を、保持すべき鉄筋に係合する位置まで屈曲させた屈曲係合部を含むものであってもよい。屈曲係合部は、例えば、折り曲げ部の一部を切起こした端部切起こし部を含む。
【００２１】
他の実施形態としての鉄筋固定プレートは、ネットコネクタの横棒と縦棒との交差部に鉄筋を固定保持するためのものであり、横棒上に位置し、縦棒を上下に通過させる縦棒受入れ開口と、鉄筋を交差部に向かって弾性的に押し付けて保持する弾性保持部と、縦棒受入れ開口を形成する開口縁部を縦棒に弾性的に係合させる弾性係合手段とを備える。この場合、鉄筋固定プレートは、さらに、当該鉄筋固定プレートが縦棒の周りに回転するのを防止する回転防止部を備えるようにしてもよい。
【００２２】
この発明に従った鉄筋固定具は、離れて位置する第１および第２のネットコネクタの横棒と縦棒との交差部に鉄筋を固定保持するためのものであり、第１ネットコネクタの横棒上に位置する第１鉄筋固定プレートと、第２ネットコネクタの横棒上に位置する第２鉄筋固定プレートと、第１鉄筋固定プレートと前記第２鉄筋固定プレートとを連結する連結部材とを備える。第１および第２鉄筋固定プレートは、それぞれ、横棒上に位置し、縦棒を上下に通過させる縦棒受入れ開口と、鉄筋を交差部に向かって弾性的に押し付けて保持する弾性保持部と、縦棒受入れ開口を形成する開口縁部を縦棒に弾性的に係合させる弾性係合手段とを備える。
【００２３】
この発明に従った鉄筋の固定方法は、以下の工程を備える。
（１）第１および第２の金網と、第１および第２の金網の間に位置して両金網の間隔を一定に保つものであり、両端が第１および第２の金網に連結される横棒と、横棒に対して交差するように配置され交差部で横棒に固定される１対の縦棒とを有するネットコネクタを用意する工程。
【００２４】
（２）ネットコネクタの横棒と縦棒との交差部に連結されるべき鉄筋を用意する工程。
【００２５】
（３）１対の縦棒を上下に通過させる１対の縦棒受入れ開口と、鉄筋を弾性的に保持する弾性保持部と、各縦棒受入れ開口を形成する開口縁部を各縦棒に弾性的に係合させる手段とを備える鉄筋固定プレートを用意する工程。
【００２６】
（４）１対の縦棒受入れ開口内に１対の縦棒を受け入れながら鉄筋固定プレートを横棒上の位置まで差し込む工程。
【００２７】
（５）鉄筋を鉄筋固定プレートの弾性保持部と縦棒との間に挿入し、弾性保持部により鉄筋を交差部に向かって弾性的に押し付けて保持する工程。
【００２８】
一つの実施形態では、１対の縦棒受入れ開口の間隔は、１対の縦棒の間隔と異なっている。この場合、上述の鉄筋固定プレートを差し込む工程は、１対の縦棒受入れ開口の間隔を１対の縦棒の間隔と同じになるように鉄筋固定プレートを弾性的に撓ませることを含む。
【００２９】
【発明の実施の形態】
図５はこの発明の一実施形態である土砂崩れ防止用金網ユニットを示す斜視図であり、図６は図５の金網ユニットに鉄筋を取付けた状態を示す斜視図である。なお、各図において同一の参照番号を付したものは、同一または相当の要素を示すものである。
【００３０】
図５および図６に示す土砂崩れ防止用金網ユニットは、第１および第２の金網１，２と、ネットコネクタ２０と、鉄筋３と、鉄筋固定プレート５０とを備える。ネットコネクタ２０は、第１および第２の金網１，２の間に位置して両金網の間隔を一定に保つものであり、両端が第１および第２の金網１，２に連結される上下の横棒２１，２２と、横棒２１、２２に対して交差するように配置され交差部で横棒に固定される左右の縦棒２３，２４とを有する。
【００３１】
鉄筋３は、鉄筋固定プレート５０を介して、ネットコネクタ２０の横棒２１，２２と縦棒２３、２４との交差部に連結された状態で第１および第２の金網１，２の間を延びている。
【００３２】
図７は、鉄筋固定プレート５０を示す断面図である。鉄筋固定プレート５０は、図５に示すように横棒２１，２２上に位置するものであり、１対の縦棒２３，２４を上下に通過させる１対の縦棒受入れ開口５１，５２と、鉄筋３をネットコネクタ２０の交差部に向かって弾性的に押し付けて保持する弾性保持部５３とを有する。
【００３３】
図示した実施形態では、縦棒受入れ開口５１，５２は、プレートを貫通する貫通穴である。また、弾性保持部５３は、鉄筋固定プレート５０の両端部を縦棒２３，２４の端部側に向かって折り曲げることによって形成されている。
【００３４】
貫通穴の形態となっている縦棒受入れ開口５１，５２を形成する開口縁部は、各縦棒２３，２４に弾性的に係合する。このことを実現するための具体的な方法として、図７に示した実施形態では、ネットコネクタ２０から分離した解放状態にある鉄筋固定プレート５０の１対の縦棒受入れ開口５１，５２の間隔Ａを、１対の縦棒２３，２４の間隔Ｂ（図８参照）よりも大きくしている。
【００３５】
鉄筋固定プレート５０を用いて鉄筋３を固定する作業は、次の通りである。
まず、第１および第２の金網１，２を保持しているネットコネクタ２０と、鉄筋３と、鉄筋固定プレート５０とを用意する。次に、１対の縦棒受入れ開口５１，５２内に１対の縦棒２３，２４を受入れながら鉄筋固定プレート５０を横棒２１，２２の上にまで差し込む。この際、１対の縦棒受入れ開口５１，５２の間隔Ａ（図７）を１対の縦棒２３，２４の間隔Ｂと同じになるように鉄筋固定プレート５０を弾性的に曲げて撓ませ、この撓ませた状態で鉄筋固定プレート５０を差し込んでゆく。したがって、図９に示すように、鉄筋固定プレート５０の装着状態では、鉄筋固定プレート５０は元の直線的な形状に復帰しようとする弾性力を発揮するので、縦棒受入れ開口５１，５２を形成する開口縁部は縦棒２３，２４に弾性的に係合し、鉄筋固定プレート５０の抜けが防止される。
【００３６】
次に、鉄筋３を、鉄筋固定プレート５０の弾性保持部（折り曲げ端部）５３と縦棒２３，２４との間に差し込む。弾性保持部５３は外方に弾性的に広がって鉄筋３を受け入れるので、鉄筋３を受け入れた状態では、元の形状に復帰しようとする弾性力を発揮し、鉄筋３をネットコネクタ２０の交差部に向かって弾性的に押し付けて保持する。
【００３７】
鉄筋固定プレート５０は鉄筋５０に面接触するので、鉄筋５０の取付状態では金網ユニットのがたつきが小さくなる。鉄筋３を取り外す場合には、鉄筋固定プレート５０の折り曲げ端部先端を指で外方に広げればよい。
【００３８】
図１０は、鉄筋固定プレートの他の例を示している。図示する鉄筋固定プレート６０は、１対の縦棒受入れ開口６１，６２と、弾性保持部として機能する折り曲げ端部６３とを有している。この実施形態では、図１０から明らかなように、解放状態にある鉄筋固定プレート６０は湾曲した形状をしている。解放状態にある鉄筋固定プレート６０の１対の縦棒受入れ開口６１，６２の間隔Ｃは、１対の縦棒２３，２４の間隔Ｂよりも小さくされている。
【００３９】
図１０に示す実施形態では、鉄筋固定プレート６０を縦棒２３，２４に差し込む際、鉄筋固定プレート６０を弾性的に長く伸ばして１対の縦棒受入れ開口６１，６１の間隔Ｃを１対の縦棒の間隔Ｂと同じになるようにする。したがって、鉄筋固定プレート６０の装着状態では、鉄筋固定プレート６０は短い長さの元の形状に復帰しようとする弾性力を発揮するので、縦棒受け入れ開口６１，６２を形成する開口縁部が縦棒２３、２４に弾性的に係合する。
【００４０】
図１１は、鉄筋固定プレートのさらに他の例を示している。図示する鉄筋固定プレート７０は、１対の縦棒受入れ開口７１，７２と、弾性保持部として機能する折り曲げ端部７３とを有する。この実施形態では、折り曲げ端部７３は、保持すべき鉄筋３に係合する位置まで屈曲させた屈曲係合部７４を含む。屈曲係合部７４は鉄筋３の上面部分にくさび状に係合するので、鉄筋３に対する固定力が強くなる。
【００４１】
図１２および図１３は、鉄筋固定プレートのさらに他の例を示している。図示する鉄筋固定プレート８０は、１対の縦棒受入れ開口８１，８２と、弾性保持部８３とを有する。この実施形態では、縦棒受入れ開口８１，８２は、鉄筋固定プレート８０の一部を縦棒２３，２４の端部側に向かって切起こすことによって形成されている。切起こし部８４は、縦棒２３，２４に弾性的に係合して鉄筋固定プレート８０の抜けを防止する。
【００４２】
図１２および図１３に示す実施形態の場合、解放状態にある鉄筋固定プレート８０の１対の縦棒受入れ開口８１，８２の間隔を１対の縦棒の間隔と異なるようにしてもよいし、同じになるようにしてもよい。
【００４３】
図１４は、鉄筋固定プレートのさらに他の例を示している。図示する鉄筋固定プレート９０は、縦棒受入れ開口９１を形成する切起こし部９３と、弾性保持部として機能する折り曲げ端部９２とを有する。折り曲げ端部９２は、途中位置にある一部を鉄筋３側に向かって切起こしている。この端部切起こし部９４は、弾性保持部に受け入れられた鉄筋３の上面部分にくさび状に係合するので、鉄筋３に対する固定力が強い。鉄筋３を取り外そうとする場合には、折り曲げ端部９２の先端部分を外方に広げるようにすればよい。
【００４４】
図１５は、鉄筋固定プレートのさらに他の例を示している。図示するように、ネットコネクタは、左右の縦棒２３，２４の間に中央縦棒２５を有している。鉄筋固定プレート２００は、中央縦棒２５を上下に通過させる貫通穴２０３と、両端に位置して弾性保持部として機能する折り曲げ端部２０２と、長さ方向の両端縁から内方に向かって切込まれた切込み開口２０１とを有する。左右の縦棒２３，２４は、左右の切込み開口２０１内を上下に通過する。この実施形態では、１対の切込み開口２０１が１対の縦棒受入れ開口を構成している。
【００４５】
図１７は、鉄筋固定プレート２００の長さ方向の一方端を示している。図示するように、折り曲げ端部２０２は、切込み開口２０１の存在によって、二股状の形態となっている。図示した実施形態では、解放状態にある１対の切込み開口２０１の内方端の間隔は、左右の縦棒２３、２４の間隔と異なるようにしている。したがって、図１５に示す鉄筋固定プレート２００の装着状態では、１対の切込み開口２０１の内方端が左右の縦棒２３、２４に弾性的に係合する。
【００４６】
図１６は、鉄筋固定プレートのさらに他の例を示している。図示する鉄筋固定プレート３００は、１対の縦棒２３，２４を受け入れる１対の切込み開口３０１と、両端に位置して弾性保持部として機能する折り曲げ端部３０２とを有する。図１６に示す鉄筋固定プレート３００が、図１５に示した鉄筋固定プレート２００と異なっているのは、中央に貫通穴を有していない点である。それ以外の構成は同じである。
【００４７】
図面を参照してこの発明の種々の実施形態を説明したが、それらは本発明を説明するために例示的に示したものである。したがって、本発明と同一の範囲内において、または均等の範囲内において、種々の修正や変形を加えることが可能である。そのいくつかを以下に例示的に列挙して説明する。
【００４８】
前述した実施形態では、鉄筋固定プレートは、１対の縦棒を上下に貫通させる１対の縦棒受入れ開口を有していたが、ただ１個の縦棒受入れ開口を有するものであってもよい。より具体的には、この鉄筋固定プレートは、横棒上に位置するものであって、縦棒を上下に貫通させる縦棒受入れ開口と、鉄筋を交差部に向かって弾性的に押し付けて保持する弾性保持部と、縦棒受入れ開口を形成する開口縁部を縦棒に弾性的に係合させる弾性係合手段を含むものである。例えば、図１４には、鉄筋固定プレート９０の一方端部分が示されているが、図示された部分のみで完成した鉄筋固定プレートとしてもよい。
【００４９】
縦棒受入れ開口を１個だけ有する実施形態の場合、鉄筋固定プレートが縦棒周りに回転するおそれがある。それを防止するために、鉄筋固定プレートは、好ましくは、縦棒周りの回転を防止する回転防止部を含むようにするのがよい。回転防止部は、例えば横棒に係合して縦棒回りの回転を防止する横棒係止部を含む。
【００５０】
鉄筋固定プレートの応用として、鉄筋固定具を構成するようにしてもよい。この鉄筋固定具は、離れて位置する第１および第２のネットコネクタの横棒と縦棒との交差部に鉄筋を固定保持するためのものであり、第１ネットコネクタの横棒上に位置する第１鉄筋固定プレートと、第２ネットコネクタの横棒上に位置する第２鉄筋固定プレートと、第１および第２鉄筋固定プレート間を連結する連結部材とを備える。各鉄筋固定プレートは、縦棒を上下に通過させる１個の縦棒受入れ開口と、鉄筋を交差部に向かって弾性的に押し付けて保持する弾性保持部と、縦棒受入れ開口を形成する開口縁部を縦棒に弾性的に係合させる弾性係合手段とを備える。

BACKGROUND OF THE INVENTION
The present invention relates to a landslide prevention wire mesh, and more particularly to a landslide prevention wire mesh for preventing landslides on slopes by receiving and hardening concrete.
[0002]
[Prior art]
Concrete is sometimes laid on steep slopes of mountains to prevent landslides. FIG. 1 shows a state in which concrete is laid on a mountain slope. In general, for the purpose of securing the strength of the concrete 30, the surface of the concrete 30 has an uneven shape having a concave portion 30b and a convex portion 30a.
[0003]
In order to make the concrete 30 have a concavo-convex shape as described above, a wire mesh is embedded in the convex portion 30a of the concrete 30.
[0004]
FIG. 2 shows a wire mesh embedded in the concrete 30. As shown in the figure, a pair of metal meshes 110, 110 are arranged so as to be arranged vertically and horizontally at a predetermined interval. The overall structure of the pair of wire nets 110, 110 is made by combining a number of wire net units 10 as shown in FIG.
[0005]
As shown in FIG. 3, the landslide prevention wire mesh unit 10 includes a first wire mesh 1, a second wire mesh 2, a net connector 20 that is positioned between both wire meshes 1 and 2 and keeps the distance between both wire meshes constant. And a reinforcing bar 3 shown in FIG. The first and second wire meshes 1 and 2 are typically crimp wire meshes.
[0006]
As shown in FIGS. 3 and 4, the net connector 20 includes an upper horizontal bar 21, a lower horizontal bar 22, a left vertical bar 23, and a right vertical bar 24. The upper and lower horizontal bars 21 and 22 are metal bars, and both ends thereof are connected to the first and second wire nets 1 and 2. The left and right vertical bars 23 and 24 are also metal bars, and are arranged so as to intersect the upper and lower horizontal bars 21 and 22. The horizontal bars 21 and 22 and the vertical bars 23 and 24 are welded at their intersections so that the positional relationship between them is fixed.
[0007]
The net connector 20 shown in FIGS. 3 and 4 is provided with two parallel horizontal bars 21 and 22 and two parallel vertical bars 23 and 24, but two parallel horizontal bars. And a single vertical bar intersecting them.
[0008]
As shown in FIG. 3, the landslide prevention wire mesh unit 10 has a plurality of net connectors 20 arranged at predetermined intervals. In order to strengthen the structure of the wire mesh unit 10, the reinforcing bars 3 are arranged at the intersections of the horizontal bars 21 and 22 and the vertical bars 23 and 24. The reinforcing bars 3 extend so as to connect the plurality of net connectors 20, that is, in a direction perpendicular to the paper surface in FIG.
[0009]
In the structure shown in FIG. 4, four reinforcing bars are used, and they are fixed as follows. First, two lower reinforcing bars 3 are installed on the slope. Next, the wire mesh unit 10 shown in FIG. 3 is placed on the two lower reinforcing bars 3. Next, the lower reinforcing bar 3 is lifted and positioned at the intersection of the horizontal bar 22 and the vertical bars 23, 24, and the reinforcing bar 3 and the intersecting part are wound around the thin wire 4 at that position and fixed. Next, the upper rebar 3 is positioned at the intersection of the horizontal bar 21 and the vertical bars 23, 24, and the reinforcing bar 3 and the intersection are wound around the thin wire 4 at that position and fixed.
[0010]
[Problems to be solved by the invention]
In the conventional landslide prevention wire mesh unit 10, the rebar 3 is wound around and fixed to the intersection using a thin wire 4. In the case of the net connector 20 having the shape shown in FIG. 4, four winding operations must be performed on one net connector 20. Since the wire mesh unit 10 includes a plurality of net connectors 20, the number of times that the reinforcing bars 3 are wound around the wire mesh unit 10 is very large.
[0011]
In addition, since the above winding work is performed on a steep slope, there is a risk that the reinforcing bars will slip if the winding force is weak. Therefore, careful and reliable winding work is required. The winding operation as described above is very complicated for the operator. In addition, since a lot of work time is required, the construction period is prolonged.
[0012]
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a metal mesh unit for preventing landslides that can perform a reinforcing bar fixing operation easily and in a short time. is there.
[0013]
[Means for Solving the Problems]

[0031]
The reinforcing bar 3 is connected between the first and second wire meshes 1 and 2 through a reinforcing bar fixing plate 50 in a state where the reinforcing bar 3 is connected to the intersection of the horizontal bars 21 and 22 and the vertical bars 23 and 24 of the net connector 20. It extends.
[0032]
FIG. 7 is a cross-sectional view showing the reinforcing bar fixing plate 50. As shown in FIG. 5, the reinforcing bar fixing plate 50 is positioned on the horizontal bars 21 and 22, and a pair of vertical bar receiving openings 51 and 52 that allow the pair of vertical bars 23 and 24 to pass vertically, An elastic holding portion 53 is provided that elastically presses and holds the reinforcing bar 3 toward the intersection of the net connector 20.
[0033]
In the illustrated embodiment, the vertical bar receiving openings 51, 52 are through holes that penetrate the plate. Further, the elastic holding portion 53 is formed by bending both end portions of the reinforcing bar fixing plate 50 toward the end portions of the vertical bars 23 and 24.
[0034]
The opening edges forming the vertical bar receiving openings 51 and 52 in the form of through holes are elastically engaged with the vertical bars 23 and 24, respectively. As a specific method for realizing this, in the embodiment shown in FIG. 7, the distance A between the pair of vertical bar receiving openings 51, 52 of the reinforcing bar fixing plate 50 in the released state separated from the net connector 20. Is made larger than the interval B (see FIG. 8) between the pair of vertical bars 23 and 24.
[0035]
The operation | work which fixes the reinforcing bar 3 using the reinforcing bar fixing plate 50 is as follows.
First, the net connector 20 holding the first and second wire nets 1, 2, the reinforcing bar 3, and the reinforcing bar fixing plate 50 are prepared. Next, the reinforcing bar fixing plate 50 is inserted over the horizontal bars 21 and 22 while receiving the pair of vertical bars 23 and 24 in the pair of vertical bar receiving openings 51 and 52. At this time, the reinforcing bar fixing plate 50 is elastically bent and bent so that the distance A (FIG. 7) between the pair of vertical bar receiving openings 51 and 52 is the same as the distance B between the pair of vertical bars 23 and 24. In this state, the reinforcing bar fixing plate 50 is inserted. Therefore, as shown in FIG. 9, when the reinforcing bar fixing plate 50 is mounted, the reinforcing bar fixing plate 50 exhibits an elastic force to return to the original linear shape, so that the vertical bar receiving openings 51 and 52 are formed. The opening edge portion to be elastically engaged with the vertical bars 23 and 24 prevents the reinforcing bar fixing plate 50 from coming off.
