An outer wall is assembled by arranging an outer wall panel 4 around the outer periphery of the outer wall. And 2112? A large number of concrete floor panels 6 are lined up over the entire surface of floors such as the 3rd floor and the 3rd floor, and as shown in FIGS. is placed on the small beam 3, and the concrete floor panels 6 that are adjacent to each other in the longitudinal direction of the small beam 3 are in contact with each other on their sides and are perpendicular to the small beam 3.

The side part of the concrete floor panel 6 is arranged above the main beam 2 at the wall where the concrete floor panel 6 is parallel to the small beam 3, and the end part of the concrete floor panel 6 is arranged above the main beam 2 at the wall side of the main beam 2 which is parallel to the small beam 3.

': I In the concrete floor panel 6, a cutout 7 is provided along the entire length on the upper surface side of the side part, and a joint reinforcing bar 8 is placed in this cutout 7, and the end face of the concrete floor panel 6 adjacent to the small beam 3 is placed in the cutout 7. The joint reinforcing bars 8 are inserted into the insertion holes 10 of the mounting plate 9 erected between them, and the joint reinforcing bars 8 are buried in the joint grooves 11 of the 1lt11 part between the sides of the concrete floor panel 6 formed by the notches 7. is filled with mortar 12, and the end joint groove 13 between the end faces of adjacent concrete floor panels 6 via the small beams 3 is also filled with mortar 12. However, in such a conventional example, the mounting plate 9 for holding the joint reinforcing bar 8 is erected on the small beam 3 by welding on site, which is time-consuming and requires construction by professionals. There was a problem.

[Objective of the Invention J The present invention has been made in view of the points stated above, and the object of the present invention is to eliminate the need for on-site welding as in the past (but to simplify construction by being able to hold joint reinforcing bars).
