多くの手数を必要としている。 However, in this conventional method, it is necessary to set a large number of anchor bolts, one at a predetermined position in each of the molding forms, and in addition, anchor bolts must be set in each predetermined position in the molding form in advance. It is necessary to provide bolt setting holes, and it takes a lot of effort to set so many anchor bolts into one.

なり易い。 Another simple method is to bury a steel plate of a certain size in a position where its surface is exposed from the surface of the concrete structure, and weld metal fittings to predetermined positions on the surface. However, since welding distortion appears, the mounting position is likely to be inaccurate.

The method for attaching an anchor member in a concrete structure according to the present invention is configured as described above, and includes the entire fixing plate 1 and attachment plate 2 and the PC.
Most of the steel material 4 is embedded in the concrete part 10, and moreover, the PC steel material 4 is under tension and is strongly pressed against the concrete part 10 in the direction in which the fixing plate 1 and the mounting plate 2 approach each other. Therefore, the anchor member 7 was fixed to the concrete part 10 extremely firmly,
In addition, the weight of the metal fittings 12 and the external force acting on it are:
In addition to the mounting plate 2, the load is also applied to the fixing plate 1 via the PC steel material 4, so that it can withstand sufficiently large external forces.
