FORM UNIT AND CONSTRUCTION METHOD OF CONCRETE STRUCTURE
To provide a form unit not needed to be removed, for concrete placing without using a form timbering.SOLUTION: A frame unit for placing concrete without using a form timbering has a buried panel 10, a connection member 20, a first fixture 30, a flange 23, and a second fixture 40. The connection member 20 has a separator part 21 and a male screw part 22 provided to one end thereof. The second fixture 40 has a head part 41 and a male screw part 42, the buried panel 10 has a hole 13 allowing penetration of the male screw part 42 of the second fixture 40, the first fixture 30 is a protrusion member having an end face 31 for buried panel rear face abutting, and has the male screw part 22 of the connection member 20 and a female screw part 33 screwed with the male screw part 42 of the second fixture 40. A sum of an abutting area of the flange 23 to a buried panel surface 12, and an abutting area of the first fixture 30 to a buried panel rear face 11 is 2% or more of the one surface area of the buried panel 10.SELECTED DRAWING: Figure 1
【課題】型枠支保工を利用せずコンクリート打設を行うための、取り外し不要の型枠ユニットを提供する。【解決手段】本開示は、型枠支保工を利用せずコンクリート打設を行うための型枠ユニットであって、埋設パネル１０と、連結部材２０と、第１固定具３０と、鍔２３と、第２固定具４０を備え、連結部材２０は、セパレータ部２１と、その一端に設けられたおねじ部２２とを有し、第２固定具４０は、頭部４１とおねじ部４２を有し、埋設パネル１０は、第２固定具４０のおねじ部４２が貫通可能な孔１３を有し、第１固定具３０は、埋設パネル裏面当接用端面３１を有する凸状部材で、その軸部に、連結部材２０のおねじ部２２及び第２固定具４０のおねじ部４２と螺合するめねじ部３３を有し、鍔２３の埋設パネル表面１２への当接面積と、第１固定具３０の埋設パネル裏面１１への当接面積の合計が、埋設パネル１０の一方の表面積の２％以上である。【選択図】図１
