Description

【0001】
本発明は、高速道路施工時や架橋施工時等にその高速道路や架橋等の下方に足場用として吊設され、複数の足場用板材を敷き詰めるための足場用吊り枠に関する。
【0002】
【従来の技術】
従来、足場用パイプを接続するには、例えば、図12に示すようなジョイント101を使用していた。このジョイントは上下に分割された断面略円弧状のジョイント単体102、103の間に前後の足場用パイプ104、105を差し入れてボルト106で締め付けてこれらの足場用パイプ104、105を接続していた。
ところが、これにおいては、ジョイント101の構造が複雑であり、接続作業も困難であるという問題があった。
また、従来の足場用パイプ104、105は、それぞれ一本ずつの単体で使用されているために、平らな足場用板材を使用して平らな足場を組むのには適していないという問題があった。
【0003】
また、本出願人が先に出願した足場用吊り枠として、図13に示すものがある。これは、上下の短管状の丸パイプ201、202を横方向に複数列設して、これら上下の短管状の丸パイプ201、202にそれぞれ若干小径の長管状の丸パイプからなる各親パイプ203、204が連通して挿入されて、これらの親パイプ203、204の上下位置を保持するように構成することによって足場用吊り枠205が造られるようになっている。
更に、足場用吊り枠205の下部の長管状の親パイプ204の一端に若干大径の連結用丸パイプ206を嵌めてビス又はボルト、ナットで接続固定されていて、この連結用丸パイプ206に他の足場用吊り枠の下部の長管状の丸パイプを嵌め込んで一直線状になるように接続されるようになっている。
ところが、これにおいては、連結用丸パイプ206に他の足場用吊り枠の下部の長管状の丸パイプを嵌め込んで接続するには、この他の足場用吊り枠を水平向きにして嵌め込まなければならないために、その作業が行い難いという問題があった。
【0004】
【発明が解決しようとする課題】
本発明は、足場用吊り枠の連結作業が行い易く、作業員が安全に足場を施工することができ、下方が川又は海あるいは作業車等の届かない場所でも一定の作業方法で容易に足場を施工することができ、しかも安価に施工することができる足場用吊り枠を提供する事を目的としている。
