PROBLEM TO BE SOLVED: To lock and hold a rising part (an upper-end side screw) positioned and adjusted before placing foundation concrete, so that the rising part is held even after placing the foundation concrete by improving an upper connecting structure to prevent a number of anchor bolts arranged in parallel from being inclined or displaced. SOLUTION: In a supporting device 1 for an anchor bolt, a template 8 connected to each of all the anchor bolts 7A, 7B by the upper-end side screw 7a, and a connection auxiliary plate 27 connecting the adjacent anchor bolts 7A, 7B to each other by the upper-end side screw 7a are arranged in parallel. A spacer 26 fitted to the upper-end side screw 7a is provided between the template 8 and the auxiliary plate 27. The template 8 and the auxiliary plate 27 are screwed to the upper-end side screw 7a in a state that the spacer 26 is sandwiched and held between them. COPYRIGHT: (C)2007,JPO&INPIT
