STRUCTURE OF CONCRETE PERMANENT FORM
PROBLEM TO BE SOLVED: To solve a problem with the conventional permanent form that when working in a small space between a permanent form and the ground and others behind the permanent form, assembly of the permanent form is prevented because of the difficulty when working behind the permanent form, or an unreliable permanent form is assembled due to the tight work condition.SOLUTION: A structure of a permanent form of the invention allows panels to be overlaid from the front surface and a piled wall body 3 to be stabilized using a tensile member fixing means 6 that may be reached by a hand from the front surface or above, even when there is no space behind the permanent form for a person to enter. Also, the panels are unlikely to fall off because their buttress part 2c is embedded in concrete 10 or a light-weight banking.
【課題】従来の残存型枠では、残存型枠と背後に地山等との空間が狭い現場状況の場合、背面での作業が困難なため、残存型枠の組立が出来ない。あるいは、窮屈な作業状況で不確実な残存型枠を組立てることになる。【解決手段】本発明の残存型枠の構造は、残存型枠の背後に人が立入る空間がない場合でも、前面からパネルを積重ねて、前面または上方から手の届く引張材固定手段６を使って、積重ね壁体３を安定させることが出来る。また、控え壁部２ｃがコンクリート１０や軽量盛土の中に埋め込まれるため、パネルが剥がれる恐れがない。【選択図】図６
