DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is a plate having a similar rounded shape on a lower frame of a window frame having a planar rounded shape, that is, an arc shape in a plan view. Mounting device for mounting.

(Prior Art) FIG. 3 shows a conventional mounting device for mounting a set board to a window frame of a flat rounded window. This flat rounded window frame includes an upper frame (not shown) and a lower frame 1 formed by curving an aluminum extruded material into a flat rounded shape such that the outdoor side end (the left end in the figure) is the convex side. Framed by the left and right side frames (not shown) made of linear aluminum extrusion,
The curved glass 2 having a flat rounded shape is fitted in the window frame in a dead-fitting manner. In this window frame, only the lower frame 1 is shown, but upper and lower frames and left and right side frames are fixed to the building frame 3 through angle members 4, anchor members 5, mounting members 6, and the like.

Then, the set board 7 has a mold material having a flat plate-shaped main body 7a and an edge 7b having a U-shaped cross section formed at one side end (inner side end) of the main body 7a. It is formed by bending into a planar rounded shape such that the outer end portion is on the convex side.
When installing the set plate 7, a plurality of anchor metal pieces 8 are fixed at predetermined positions on the building frame 3, and a bolt hole (not shown) is provided in the horizontal plate portion 9a at the upper end of each anchor metal piece 8. The vertical plate portion 9b of the L-shaped mounting hardware 9 is fixed by welding. On the other hand, on the lower surface of the set plate body 7a of the set plate 7, a screw shaft portion 10 is fixed by welding at a position corresponding to the above bolt hole on the side of the mounting metal member 9 fixed to the anchor metal member 8 so as to project downward. . Then, the set plate 7 is attached to the mounting plate 9 from above.
Bring it up and pass each screw shaft portion 10 through the bolt hole of each mounting hardware 9, and screw the nut 11 onto the tip end portion of the screw shaft portion 10 to tighten it. Further, the outdoor side end of the set plate body 7a is fixed to the indoor side surface of the window frame 1 with a screw 13 via an L-shaped mounting member 12,
The lower surface of the edge 7b at the opposite end is supported on the indoor decorative plate 14.

(Problems to be Solved by the Invention) In the above-described conventional plate mounting device, when mounting the plate 7, the screw shaft portion 10 and the anchor metal member 8 that are fixedly protruded from the lower surface of the plate body 7a are interposed. If the bolt holes of the mounting hardware 9 fixed on the side of the building body 3 are misaligned, the screw shaft portion 10 cannot be passed through the bolt hole, so positioning of each screw shaft portion 10 with respect to the bolt hole. Must be performed very carefully, and if there is a deviation in the positional relationship between the two, it is necessary to remove the screw shaft portion 10 once, which is a very troublesome work. In addition, since the screw shaft portion 10 is fixed to the set plate 7 by welding, the screw shaft is inclined and fixed with respect to the normal vertical position due to thermal distortion at the time of welding, or the fixing position is easily displaced. There was also. Further, when the aluminum extruded die material for the set board 7 is bent into a plane R shape by a roll bender, which is the simplest as a bending machine, the cross section of the die material is asymmetric and the wall thickness is relatively thin. Since the second moment of area is small, the main plate body of the mold member 7 concerned
There is a problem that 7a causes a warp (distortion) as shown by the alternate long and short dash line in FIG. In this case, it is not preferable that the plate main body 7a has a sufficient thickness so that such warpage does not occur, because the material cost of the mold material becomes high.

The present invention solves such a problem.
