<P>PROBLEM TO BE SOLVED: To provide an apparatus for temporarily coffering the periphery of a columnar object which can be reused by moving one partition with bottom plate for work space formation even for construction to columnar objects such as bridge piers having different cross-sectional shapes or for a plurality of columnar objects arranged side by side. <P>SOLUTION: In a temporary coffering apparatus, a plurality of divided units 20a which are longitudinally divided are assembled to surround the periphery of a columnar object 10 to form a partition 20 with bottom plate for work space formation, and the inside is dried. A bottom plate 22 includes a window 25 that is vertically opened, and a cutoff support plate 24 is provided which closes the window 25 and includes an attachment hole 26 through which the columnar object 10 is vertically inserted. In the cutoff support plate 24, a plurality of divided support plate units are assembled to form the attachment hole 26 for attaching the columnar object. The cutoff support plate 24 is fixed around the outer periphery of the columnar object inserted through the inside of the attachment hole. The cutoff support plate 24 and the bottom plate 22 of the partition 20 with bottom plate for work space formation are overlapped with each other in a vertical arrangement while interposing cutoff packing between them to close the window 25 of the bottom plate 22. <P>COPYRIGHT: (C)2013,JPO&INPIT |
