FORM UNIT AND CONCRETE STRUCTURE CONSTRUCTION METHOD
To provide a form unit that is unnecessary to remove for conducting concrete placing without using form timbering.SOLUTION: A form unit comprises an embedded panel 10, a connection member 20, a first fixture 30, a collar 23, and a second fixture 40. The connection member 20 has a separator part 21 and a male thread part 22 that is mounted at its one end. The second fixture 40 has a head part 41 and a male thread part 42. The embedded panel 10 has a hole 13 through which the male thread part 42 of the second fixture 40 can be penetrated. The collar 23 has a hole 24 through which the male thread part 42 of the second fixture 40 can be inserted and an end surface 23A for abutting an embedded panel surface. The first fixture 30 is a convex member that has an end surface 31 for abutting an embedded panel backside and its shaft part has a female thread part 33 that screws the male thread part 22 of the connection member 20 and the male thread part 42 of the second fixture 40. The sum of an abutment area to an embedded panel surface 12 of the collar 23 and an abutment area to an embedded panel backside 11 of the first fixture 30 is 2% or more of one surface area of the embedded 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】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、鍔２３は、第２固定具４０のおねじ部４２が貫通可能な孔２４と、埋設パネル表面当接用端面２３Ａ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
