【0001】
【発明の属する技術分野】
本発明は、橋梁などの床版を打設するための設備に関する。
【0002】
【従来の技術】
例えば、図10のように、左右一対のI形断面の主桁1のフランジ41に、それぞれ、支保工支持フレーム42を移動自在に組み付けると共に、これらの支保工支持フレーム42によって横長の支保工梁43を吊り下げ、更に、支保工梁43上に丈の高い型枠支保工44を立設させた床版打設設備が機関誌などに紹介されている。
【0003】
【発明が解決しようとする課題】
ところが、主桁1同士は、一般に、図示しない添接板を介して連結されているため、支保工支持フレーム42を主桁1の長さ方向に移動させようとすると、添接板が障害になって支保工支持フレーム42を円滑に移動させることが難しい。
また、上記型枠支保工44の高さが高いため、作業上の危険度が増加する虞れがある。更に、支保工梁43が主桁1より下方に吊り下げられているから橋脚を乗り越えることができない。従って、橋脚の手前で作業を中断して支保工梁を当該橋脚より先方の工事区間に付け替える支保工梁の付替工事が必要になる。
【0004】
本発明は、係る従来の問題に鑑みてなされたものであり、その目的とするところは、支保工梁の付替工事などの余分な工事が不必要であるばかりでなく、型枠などの移動が円滑で、かつ、安全に作業が行える床版打設用設備を提供することにある。
【0005】
【課題を解決するための手段】
即ち、請求項1に記載の床版打設用設備は、主桁間に架橋した横梁と主桁の外側に張り出した仮設梁によって形成した梁を橋軸方向に所定の間隔で設置し、横梁上に仮設した橋軸方向のレール上に台車付主型枠を設置すると共に、仮設梁上に仮設した橋軸方向のレール上に台車付張出部型枠を設置させたことを特徴としている。
【0006】
また、請求項2に記載の床版打設用設備は、前記主型枠及び前記張出部型枠にサポートジャッキを設けてコンクリート打設時に各台車の車輪に荷重が作用しないようにしたことを特徴としている。
また、請求項3に記載の床版打設用設備は、前記仮設梁上に敷設した上屋移動用レールに上屋を移動自在に設置したことを特徴としている。
【0008】
【発明の実施の形態】
以下、図面を参照しながら本発明の実施の形態について説明する。
図1に示すように、梁12は、主桁1間に架橋させた横梁2と、主桁1の外側に張り出させた仮設梁20により形成されている。そして、この梁12は、橋軸方向に所定の間隔で設置されている。仮設梁20は、主桁1の横腹に溶接され、工事終了後に取り払うようになっているが、主桁1の横腹に固定したブラケットに添接板を介して取り付けて撤去し易いようにしてもよい。なお、仮設梁20には、横梁2と同種の梁材を使用する。
【0009】
そして、主桁1に平行、すなわち、橋軸方向に敷設した横梁2上のレール3に台車付の主型枠6を設置する。主型枠6は、図3に示すように、台車5に取り付けた左右一対の上下用油圧シリンダー7によって支持されているが、主型枠6と台車5との間に設けた横送り用油圧シリンダー15によって右又は左方向に位置調整できるようになっている。また、主型枠6は、多数のジャッキ14により橋軸と直交する方向にキャンバーをつけることができるようになっている。
【0010】
主型枠6は、中央部型枠4と、その左右両側に取り付けたハンチ部型枠10から構成されている。そして、ハンチ部型枠10は、ハンチ部型枠10と中央部型枠4との間に架橋させた伸縮用油圧シリンダー16によって起伏されるようになっている。また、主型枠6は、図2に示すように、台車5に設けた走行装置17によって前・後進できるようになっている。主型枠6は、図2のような1ブロック単位で使用してもよいが、数ブロック連結させた状態で使用してもよい。
【0011】
更に、図3に示すように、中央部型枠4の構成部材の一つである横枠8の両端部に、サポートジャッキ18を下向きに取り付ける一方、このサポートジャッキ18に対向するように横梁8上にサポートジャッキ用H型鋼19を敷設する。しかし、サポートジャッキ18をサポートジャッキ用H型鋼19上に上向きに設置しても良い。
【0012】
一方、主桁1に平行、すなわち、橋軸方向に敷設した仮設梁20上のレール21に台車付の張出部型枠22を搭載する。張出部型枠22は、台車23に取り付けた左右一対の上下用油圧シリンダー(不図示)によって支持されているが、張出部型枠22と台車23との間に設けた横送り用油圧シリンダー28によって右又は左方向に位置調整できるようになっている。また、台車23は、台車23に設けた走行装置(図示せず)によって前・後進するようになっている。
【0013】
更に、張出部型枠22の両端部に、サポートジャッキ29を下向きに取り付ける一方、このサポートジャッキ29に対向するように仮設梁20上にサポートジャッキ用H型鋼30を敷設する。しかし、サポートジャッキ29をサポートジャッキ用H型鋼30上に上向きに設置しても良い。
また、上記台車5及び23から足場を吊り下げる場合は、横梁2及び仮設梁20を越えるため、昇降式の足場にする。
【0014】
また、図1に示すように、仮設梁20の最外端部に設けた左右一対の上屋移動用レール31上に上屋32を移動自在に配設し、雨天時でも作業ができるようにする。この上屋32は、コンクリートの養生にも適している。
上屋32は、図1に示すように、山形状のフレーム33上にテント地34を被せた構造で、図4のように、前後方向に縮めることもできるようになっている。また、この上屋32は、図4に示すように、レールクランプ35、自走装置36、ストッパー37を備えている。
【0015】
次に、上記移動用型枠を使用したコンクリート打設作業について説明する。
図5に示すように、個々の走行装置17により所定の床版打設位置まで主型枠6及び張出型枠22を移動させる。移動終了後、図6のように、各台車5及び23に設けた上下用油圧シリンダー7、横送り用油圧シリンダー15及び28、伸縮用油圧シリンダー16及び主桁1と張出部型枠22間に設けたフレーム伸縮用棒ジャッキ38によって主型枠6及び張出型枠22を固定する。
【0016】
型枠固定終了後、図7のように、上下用油圧シリンダー7を下げてサポートジャッキ18及び29にて主型枠6及び張出型枠22を支持する。
そして、図8に示すように、他の場所で組み込んだ鉄筋39を図示しないクレーンで主型枠4及び張出型枠22内に組み込む。そして、図9に示すように、コンクリート40を打設し養生後、主型枠4及び張出型枠,22を降下させて、次工程に移動させる。そして、図6〜図9の工程を繰り返し行う。
【0017】
【発明の効果】
上記のように、本発明は、主桁間に架橋した横梁と主桁の外側に張り出した仮設梁により形成した梁を橋軸方向に所定の間隔で設置し、横梁上に仮設した橋軸方向のレール上に台車付主型枠を設置すると共に、仮設梁上に仮設した橋軸方向のレール上に台車付張出部型枠を設置させたので、支保工梁の付替工事などの余分な工事が不必要であるばかりでなく、主型枠や張出型枠などの型枠の移動を円滑に行えるようになった。また、梁から主型枠や張出型枠などの型枠までの高さが従来に比べてかなり低いので、安全に、かつ、効率的に作業を行うことができるようになった。
