<P>PROBLEM TO BE SOLVED: To provide an anchor mounting device for civil engineering configured to increase a water-stop effect in a joint portion between a nut and a washer, and prevent, in using resin-coated nut and washer, the resin in a joint portion between the nut and the washer from being separated, while reducing an influence on fastening torque. <P>SOLUTION: The anchor mounting device 1 for civil engineering comprises: a long civil-engineering anchor 11 such as a threaded lock bolt; a nut 12 to be screwed to a head of the civil-engineering anchor 11; a square washer 13 having an insertion hole formed therein and allowing the civil-engineering anchor 11 to be inserted; and a tapered washer 14 having a conical inclined face, which is inclined from a maximum outer diameter portion having an outer diameter larger than the inner diameter of the insertion hole of the square washer 13 to a minimum outer diameter portion having an outer diameter smaller than the inner diameter of the insertion hole of the square washer 13. <P>COPYRIGHT: (C)2012,JPO&INPIT |
