 FIG. 1 is a sectional view showing a preferred embodiment of a fastener for fixing an outer wall material according to the present invention together with a body and a part of the outer wall material, and FIG. 2 shows a coupling metal fitting in the fastener for fixing the outer wall material together with a beam steel frame. FIG. That is, the fastener for fixing outer wall material generally indicated by reference numeral 1 is a primary fastener 10 fixed to a concrete beam 2a of a body 2 in a state of protruding substantially horizontally toward a body outer wall surface side, and a PC board. The outer fastener 4 includes a rear surface 4a of the outer wall member 4 and a secondary fastener 20 made of an L-shaped metal fitting interposed between the primary fastener 10.

The primary fastener 10 includes a metal plate 11 a to be welded to the steel frame 3 of the concrete beam 2 a and a coupling fitting 11 made of a cap nut 11 b as a female screw portion integrally provided on the metal plate 11 a and the coupling fitting 11. The bracket portion 12 is tightly connected via a screw member 13 that is screwed with the cap nut 11b, and a tip portion 12a has a screw member insertion hole (not shown) that is a tightly connected portion with the secondary fastener 20. The metal fitting 11 is manufactured by welding a pair of cap nuts 11b to both ends of the metal plate 11a in the width direction. Preliminarily welded to the lower end flange 3a of the steel frame 3 so as to match the direction and correspond to the mounting position of the outer wall member 4. Further, preferably, the steel frame 3 is reinforced by welding the stiffener 3b corresponding to the welding position of the joint fitting 11.
