PURPOSE:To facilitate the fitting work of anchor rods at site to joint a wall panel with a footing concrete and reduce danger of the fitting work, by previously burying insert nuts to screw up anchor rods so as to expose on the joining face with the footing concrete in the lower part of the wall panel. CONSTITUTION:Insert nuts 7 are previously buried so as to protrude in the recession 8 of a wall panel 1. This insert nuts 7 are made by a different dia. rod cut short and provided with a female screw 9 from the one end thereof so that the female screw 9 is buried to expose at the recession 8 side. The anchor rods 3 are made of a deformed rod having the same dia. with the insert nuts 7 and provided with a male screw to fit to the female screw 9 at the one end thereof. The anchor rods 3 are screwed up in the insert nuts 7. The footing concrete is placed so as to fill the recession 8. In this way, the anchor rods can be easily fitted in a short time.
