【発明の属する技術分野】
本発明はジベル筋及びこれを用いた半プレキャストコンクリート板に関する。
【０００２】
【従来の技術とその問題点】
従来、半プレキャストコンクリート板（以下半ＰＣａ板という）を使用して建物を構築する工法として、図１０に示すように、工場で薄肉の半ＰＣａ板部２１を打設するとともにこれにジベル筋２２を立設し、この半ＰＣａ板を現場に搬送して、現場においてその薄肉の半ＰＣａ板部２１上に現場打ちコンクリート２３を打設してコンクリート合成板２４を成形する工法がある。
【０００３】
このような工法に使用される前記ジベル筋２２として、従来、図１０及び図１１に示すように、２本の下端筋２５，２５と１本の上端筋２６間に跨がって両側にラチス筋２７，２８を溶接固着して横断面が略三角形の立体的なトラス筋としたものがある。
【０００４】
【発明が解決しようとする課題】
ところで、前記のような半ＰＣａ板においては、抵抗機構を考えると半ＰＣａ板部２１のコンクリートの方に力が流れ、下端筋２５，２５は半ＰＣａ板部２１との定着程度の用しかなしていない。また、上記のジベル筋は高価であるため、その材料の使用量をできる限り抑えたい要望がある。
【０００５】
そこで本発明は、前記のラチス筋自体に半ＰＣａ板部２１との定着部を設けて前記従来の両下端筋２５，２５をなくし、省材料化、製造の容易化、製品の低廉化などを図るジベル筋とこれを用いた半ＰＣａ板を提供することを目的とするものである。

【０００９】
【発明の実施の形態】
図１乃至図９に示す実施例に基き本発明の実施の形態について説明する。
図１乃至図６は第１実施例を示す。
【００１０】
図１乃至図３はジベル筋を示すもので、該ジベル筋１は、１本の上端筋２と１本のラチス筋３とからなる。
ラチス筋３は、前記上端筋２の軸方向と直交する方向に配置した水平筋４ａの一端から上端筋２の軸方向でかつ上端筋２側へ傾斜した一側（例えば左側）の斜め筋５ａを立ち上げ、該一側の斜め筋５ａの上端を上端筋２の上面で折曲して該頂部６ａから前記一側の斜め筋５ａと反対側へ傾斜した他側（例えば右側）の斜め筋７ａを連続形成し、該他側の斜め筋７ａの下端に、前記水平筋４ａと並行する水平筋４ｂを連続形成し、更に、該水平筋４ｂから前記と同様に一側の斜め筋５ｂ、頂部６ｂ、他側の斜め筋７ｂ、水平筋４ｃを繰り返し連続形成して構成されている。前記斜め筋５ａと７ａ、５ａと７ｂが夫々ハの字状の一対の斜め筋となる。
【００１１】
そして、前記ラチス筋３の頂部６ａ，６ｂ…が上端筋２に溶接等で固着されている。
前記上端筋２及びラチス筋３は鉄筋、ステンレス筋、複合繊維棒などを使用する。
【００１２】
前記のように構成したことにより、１本の線材を成形機により連続的に曲げ加工してラチス筋３を製造でき、そのラチス筋３の製造が容易である。
また、このラチス筋３に対して１本の上端筋２を溶接等で固着するのみでジベル筋１を組み立て製造できるため、前記従来のように２本の下端筋と１本の上端筋を使用するものに比べてジベル筋の使用材料が１／４〜１／３程少なくてよい。更に、組み立て時の溶接点数も１／３に減少し、工数を低減してジベル筋の組み立て時間の短縮が行え、ジベル筋の製造容易化、低廉化を図ることができる。
【００１３】
更に、１本の線材からなるラチス筋であっても該ラチス筋３を、上端筋２を中心としてその両側（左右）にバランスよく配置でき、かつ、水平筋３ａ，３ｂ…を多数並列的に配置したので、そのジベル筋１の仮設置が可能になる。
【００１４】
更に、このジベル筋１は、上下はもちろん、前後、左右の力にも対処できる立体形状となる。
更に、前記のように各水平筋４ａ，４ｂ…が上端筋２に直交して並行に配置さているので、これら隣接する水平筋間に空間が形成される。したがって、これらの空間を通じて設備配管や配筋作業がしやすくなる。
【００１５】
前記のように形成されたジベル筋１は、所望の数、並列的にコンクリート中に埋設するもので、例えば図４乃至図６に示すようにコンクリート板中に埋設して使用する。
【００１６】
図４及び図５は前記のようなジベル筋１を用いた半ＰＣａ板８を示し、図６は該半ＰＣａ板８を使用したプレキャストコンクリート合成板を示す。
前記半ＰＣａ板を製造するには、工場のベッド上において、前記ジベル筋１を所望本並列して立設し、図４及び図５に示すようにジベル筋１の下部が埋設される程度にコンクリートを打設して薄肉の半ＰＣａ板部９を成形し、表面にジベル筋１を突設した半ＰＣａ板８を製造する。
【００１７】
このように製造された半ＰＣａ板８のジベル筋１は、その水平筋４ａ，４ｂ…によりＰＣａ板部９に確実に保持され、該半ＰＣａ板８の工場からの搬送時にジベル筋１が外脱することがない。
【００１８】
次に、前記の半ＰＣａ板８を現場に搬送し、現場においてその半ＰＣａ板８を、そのジベル筋１を上向きにして床部等に水平に配置し、その上面に図６に示すようにジベル筋１が埋設されるようにコンクリート１０を打設する。これにより、ジベル筋１によって半ＰＣａ板部９と現場打ちコンクリート１０とが連結された半ＰＣａ合成板１１が成形される。この成形状態において、水平筋４ａ，４ｂ…が半ＰＣａ板部９と強固に係合し、上端筋１が現場打ちコンクリート１０と強固に係合するため、半ＰＣａ板部９と現場打ちコンクリート１０とが強固に結合される。
【００１９】
なお、前記の半ＰＣａ板８は、これを現場で垂直に配設してコンクリート型枠として用いてもよい。
図７は本発明のジベル筋の第２実施例を示す。
【００２０】
本実施例のジベル筋１Ａも１本の上端筋２と１本のラチス筋３Ａとからなる。

【００２１】
本第２実施例のジベル筋１Ａも前記第１実施例のジベル筋１と同様の作用、効果を発揮できる。
更に、本第２実施例のジベル筋１Ａを前記第１実施例のジベル筋１と同様に図４及び図５に示すように半ＰＣａ板部９に埋設し、更にこれを用いて図６に示すように半ＰＣａ合成板を成形することにより、前記と同様の作用、効果を発揮する。

【００２３】
本第３実施例のジベル筋１Ｂも前記第１実施例のジベル筋１と同様の作用、効果を発揮できる。

【００２４】
図９は本発明のジベル筋の第４実施例を示す。
本実施例のジベル筋１Ｃも１本の上端筋２と１本のラチス筋３Ｃとからなる。
ラチス筋３Ｃは、前記上端筋２の軸方向に対して傾斜する方向に配置した水平筋４ａの一端から上端筋２の軸方向と直交する方向において上端筋２側へ傾斜した一側（例えば右側）の斜め筋５ａを立ち上げ、該一側の斜め筋５ａの上端を上端筋２の上面で折曲して該頂部６ａから前記一側の斜め筋５ａと反対側へ傾斜した他側（例えば左側）の斜め筋７ａを連続形成し、該他側の斜め筋７ａの下端に、前記水平筋４ａと並行（上端筋２の軸方向に対して傾斜）する水平筋４ｂを連続形成し、更に、該水平筋４ｂから前記と同様に一側の斜め筋５ｂ、頂部６ｂ、他側の斜め筋７ｂ、水平筋４ｃを繰り返し連続形成して構成されている。前記斜め筋５ａ，７ａと５ｂと７ｂが夫々ハの字状の一対の斜め筋となる。

【００２７】
なお、前記各実施例のジベル筋は、前記の半ＰＣａ板以外のコンクリート間の接合部材としても応用できる。
【００２８】
【発明の効果】
以上のようであるから、本発明のジベル筋においては、そのラチス筋が１本の線材によって上下はもちろん、前後・左右の力にも対処できるように立体形状に形成できる。そのため、前記従来の２本の下端筋を有するものと比較して使用材料が約１／４〜１／３に減少し、組み立て時の溶接点数も約１／３に減少する。
【００２９】
従って、ジベル筋の材料費の低減化を図り、かつ組み立て工数の低減による作業の能率化、組み立て時間の短縮化を図ることができる。
更に、ラチス筋の水平筋が上端筋と直交する方向に配置されているため、該隣接する水平筋間には前記従来の下端筋のような鉄筋が存在せず、前記従来のような上端筋と並行する下端筋を有するものに比べて設備配管や配筋作業がしやすくなる。
【００３０】
また、前記本発明のジベル筋を使用した半ＰＣａ板においては、前記本発明のジベル筋が、その水平筋によってＰＣａ板部に強固に連結され、前記ジベル筋の効果を有するＰＣａ板を提供できる。
