Next, a panel mounting hardware and its mounting structure according to a second embodiment of the present invention will be described with reference to the drawings. The same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

FIG. 5 shows a floor panel mounting structure 30. Since this mounting structure is different only in the mounting hardware 13 in the floor panel mounting structure 11 of the first embodiment, only the configuration of the mounting hardware 31 used in this embodiment will be described in detail below.

FIG. 6 shows a mounting hardware 31 in which the clip portion and the guide portion of the clip hardware are separated. The components of the mounting hardware 31 are the same plate washer 21 as in the first embodiment, a clip member 32 which is a clip portion of a clip metal article obtained by bending a strip-shaped plate, a guide member 33 which is a guide portion, and a nut which is a screw component. 34.

The clip member 32 comprises a clip portion 32a whose one end is locked to one upper flange 12a of the beam 12, and this clip portion 32a is the upper flange 12a.
It is bent along the cross-sectional shape of. The tip portion 32b of the clip portion 32a is slightly widened outward so that the upper flange 12a of the beam can be easily pinched.

The other end of the clip member 32 is connected to the beam 12
Is extended to the joints of the floor panels 16 and 17 on the upper flange 12a, and the bolt shaft 32c, which is a threaded portion, is fixed thereto by welding in the vertical direction. The length of the bolt shaft 32c is such that it does not project from the surfaces of the floor panels 16 and 17.

The guide member 33 is bent so as to have a U-shaped cross section, and the side surfaces 33a and 33b thereof are on the floor panel 1.
A vertical surface is formed so as to come into contact with the short side edge of 6, 17. The tip of the side surface 33a is placed on the surface of the clip member 32, and the tip of the side surface 33b is placed on the surface of the upper flange 12a. Therefore, the side surface 33b is formed longer than the one side surface 33a by the thickness of the clip member 32.
