ものである。The applicant of the present invention first developed a mounting metal fitting satisfying the above-mentioned construction conditions and filed a registration application in Japanese Patent Application No. 5-17804. As shown in FIG. 9, this mounting bracket has a main bracket 51, a bolt 52, a kill plate 53, and a pedestal plate 54, and an anchor portion 55 of the main bracket 51 is attached to a panel 56.
The bolts 52 are passed through the joint seat portion 58, the box-shaped base plate 54 is welded to the steel beam 59, and the lower end of the bolt 52 is put into the base plate 54 to make the steel beam. 59, kill plate 53
The pedestal plate 54 is closed with the bolt 52 positioned.

のまま使用することは次の理由から好ましくない。According to this mounting member, the following problems cannot be solved. Since the anchor portion 55 of the main metal fitting 51 has a large mass, it is difficult to provide the main metal fitting 51 near the end portion of the panel 56 due to the problem of fixing strength with concrete. Since the pedestal plate 54 is preliminarily formed in a box shape and is welded onto the steel beam 59, the welded portion is fillet welding and only the outer peripheral portion, and the proof stress is reduced. In order to compensate for this, it is necessary to weld the three sides of the box, that is, the sides other than the side facing the panel 56, and the specific gravity of the welding operation becomes large. It is conceivable to use an assembly in which the box shape is stopped and a channel steel or an iron plate is welded in a substantially U shape, but it is not preferable to use these as they are for the following reason.

のような溶接は技術的に困難で、殊に内側の部分６４の
溶接作業は大変厄介である。In the case of the channel steel 61, as shown in FIG. 7, the inner surface of the end of the sleeve piece 62 reaches the outer surface while drawing the arc surface 63, so that the portions 64 and 65 hatched with respect to the skeleton B are shown.
Such welding is technically difficult, and in particular, the welding operation of the inner portion 64 is very troublesome.

明はこれらの課題を解決することを目的とする。In the case of the assembly 66, as shown in FIG. 8, since the welded portions 67 and 68 at the lower end of the sleeve piece 62 are fillet welded, the yield strength is low. Further, as in the case of the channel steel, the work is difficult at the inner welded portion 67. The present invention aims to solve these problems.

ると、パネルの荷重が躯体に伝えられる。The panel is hung by a crane and carried to the mounting location of the skeleton. Here, with the spherical head of the support bolt facing down, hold down the shaft of the support bolt and insert it into the insertion hole of the metal fitting from below, and temporarily rotate it into the screw hole of the overhanging part of the joint metal fitting of this panel, and move the panel. Lower the bolt head into the stupid hole of the fixed hardware. Further, when the panel is moved forward, backward, leftward and rightward and comes to a predetermined position, the holding metal piece is welded to the upper surface of the base of the fixed metal piece at the three corners of the outer periphery. Here, when the support bolt is adjusted and the head is brought into contact with the body, the load of the panel is transmitted to the body.

伝達される。The method of coping with various stresses generated in the panel is as follows. First, the stress in the direction perpendicular to the panel surface, that is, the stress in the direction of moving the panel away from or close to the frame, is to join the embedded portion of the joint metal and the joint of the reinforcing bar, the edge of the insertion hole of the retainer metal, and the shaft portion of the support bolt. It is transmitted to the body through the surface.
