<p><P>PROBLEM TO BE SOLVED: To provide a marking method for allowing a worker to perform accurate marking work simply and inexpensively without requiring any special facility at site if there is an ordinary pen plotter or the like capable of being installed indoors. <P>SOLUTION: Installation positions 1a, 1e, 2a, 3 of objects to be buried such as sleeve, insert fitting or the like are printed or cut on/out of the sheet capable of being printed or cut out by actual dimension by using the pen plotter or the like based on the information about drawing to be drafted. This sheet is set on a surface of concrete to be placed to mark by using a cut-out part as template. For example, a half of one PCa plate P<SB>3</SB>is divided into three sections Z<SB>31</SB>, Z<SB>32</SB>, Z<SB>33</SB>, and the data of them is overlapped on one sheet to reduce the number of sheets used and reduce troublesome work required at site. After marking, the sheet is removed and concrete is placed in one section, and then marking and placement of concrete are performed at positions corresponding to respective sections while moving the work to the other sections sequentially. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
