FIG. 11 shows a spacer member 10 assembled at a corner portion of a floor material peripheral edge. FIG. 7 above
As can be clearly understood from the figure, the spacer member 30 according to the present embodiment is cut out at the central portion in the longitudinal direction, and the cut-out portion 3 is formed.
5 is thin at the deepest portion 35a, so that it can be bent at an arbitrary angle around the cutout portion 15.
By using such a spacer member 10, it is possible to assemble one type in correspondence with a linear portion of a floor material peripheral edge and a corner portion.

As can be clearly understood from FIG. 5, the vertical frame member 40 according to this embodiment has a central portion 40a having a U-shaped cross section, and both edges of the central portion 40a are bent and extended outward. And has a predetermined length corresponding to the height from its fixed position to the floor material 2 to the ceiling. On the lower end side of the overhang portion 40b, an insertion hole 41 corresponding to the hole portion 36 arranged in the base portion 31 of the spacer member 30 is provided.
A plurality of clip mounting holes 42 are provided along the longitudinal direction. A clip member 45 is mounted in each of the clip mounting holes 42.

The vertical frame member 40 having such a configuration is fixed around the periphery of the flooring 2, and the upper end of the adjacent frame member 40 is hung on the vertical frame member 40. The horizontal frame member 25 is fastened and fixed by the screw member 24 so as to pass. As described above, in the present embodiment, FIG.
As shown in (1), prior to assembling the wall member 5 and the ceiling panel 7, a horizontal frame member 25 and a vertical frame member 40 are assembled around the floor member 2.

For the frame members 25 and 40 assembled around the floor member 2, first, the wall member 5 is disposed on the vertical frame member 40 from the indoor side. FIG. 12 is a cross-sectional explanatory view showing the state of the assembled portion of the wall member 5 and the vertical frame member 40 after the wall member 5 has been assembled. On the outer surface side of the wall member 5, a plurality of male screw members 50 are provided substantially vertically corresponding to the clip members 45 mounted along the longitudinal direction of the frame member 40.
Are used for assembling the wall member 5, respectively.
It has a structure that engages with and clamps it. In this assembled state, the horizontal frame member 25 fixed to the upper end of the vertical frame member 40 is located on the outer surface side of the upper end of the wall material 5. The ceiling panel 7 is attached to the horizontal frame member 25 by engaging the ceiling panel 7 from above.

In this embodiment, the horizontal frame member 25 fixed so that the upper end of the vertical frame member 40 pre-assembled around the periphery of the flooring 2 is fixed to the ceiling. The case where the panel 7 is attached by being engaged from above is described, but the present invention is not limited to this. For example, the wall member 5 directly assembled on the periphery of the floor member 2 without using the vertical frame member 40 After the horizontal frame member 25 is provided at the upper end of the ceiling panel 7, the ceiling panel 7 may be engaged with the horizontal frame member 25 and attached.

FIG. 13 shows a state in which the connecting member 10 fixed to the peripheral edge of the ceiling panel 7 is assembled to the horizontal frame member 25 from above. FIG. 14 is an explanatory cross-sectional view showing a state after assembly of the connecting member 10 to the horizontal frame member 25 is completed. As described above, the horizontal frame member 25 is attached to the wall member 5.
Are fixed to the upper end of the up-down frame member 40 to which is attached, and are located on the outer surface of the upper end of the wall member 5. The horizontal frame member 25 has an opening 2 having a predetermined width capable of receiving the clip portion 13 of the connecting member 10.
When the ceiling panel 7 is attached, the clip 13 of the connecting member 10 is inserted into the opening 26 from above. In the present embodiment, such an opening 26 is formed by the horizontal frame member 25.
Along the longitudinal direction of the ceiling panel 7 at a position corresponding to the plurality of connecting members 10 fixed to the peripheral edge of the ceiling panel 7.

While fitting the rising portion 7a and the flange portion 7b of the peripheral edge of the ceiling panel 7 to the upper end of the wall material 5,
When the clip 13 of each connecting member 10 is inserted into the corresponding opening 26 from above, the retaining corner 14a
The fold 14 provided with the slidable outer edge 26 a of the opening 26. According to the insertion of the clip portion 13, the folded portion 14
Is bent inward along the edge 26a, and after the retaining corner 14a passes through the lower surface of the frame member 25, it moves outward by spring elasticity, and the retaining is effective. The folded portion 14 is urged against the edge portion 26a at a portion abutting on the edge portion 26a even after the fitting of the peripheral edge of the ceiling panel 7 and the upper end portion of the wall material 5 is completed. The engagement with the opening 26 is ensured, and the clip portion 13 of the connecting member 10 is prevented from being pulled out to the upper surface side of the frame member 25. In this manner, the ceiling panel 7 is attached to the upper end of the wall member 5 by engaging the clip portion 13 of each connecting member 10 with the opening 26 of the horizontal frame member 25.

As described above, the horizontal frame member 25 previously provided on the outer surface of the upper end of the wall member 5 is used.
Then, the ceiling panel 7 is engaged and assembled from above, so that the ceiling panel 7 can be easily and quickly attached to the upper end of the wall material 5.
