BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of a preferred embodiment of the present invention.

FIG. 1 is an exploded perspective view showing a wall material mounting structure according to the present invention. A plurality of aggregates 2 to which the wall material 1 is attached are erected in parallel with each other, similarly to the aggregate 21 shown in the above-mentioned conventional example. A rail member 3 having a C-shaped cross section is bolted to the aggregate 2 so as to be in a horizontal state, for example. Then, the wall material 1 to which wallpaper has been applied or surface-treated in advance is attached to the rail member 3 via a clip constituted by a grommet 4 and a pin 5 each formed of a synthetic resin material.

As shown in FIG. 2, the grommet 4 includes a flat U-shaped cross-section head 6 and a substantially rectangular cylindrical portion 7 integrally formed so as to extend from the head 6. Have. The inside of the cylindrical portion 7 and the opening 8 formed in the head 6 communicate with each other coaxially, and the upper and lower portions of the peripheral wall of the cylindrical portion 7 in FIG. A pair of flexible leg pieces 9 are formed at the top and bottom so as to cut. An engaging claw 9a having a triangular cross section protruding outward from the outer surface of the cylindrical portion 7 protrudes from an outer surface of the flexible leg piece 9, and a cylindrical shape is formed on an inner surface of the flexible leg piece 9. An inward projecting portion 9b projecting inward from the inner surface of the portion 7 is provided.

The pin 5 has a substantially rectangular bottomed cylindrical shaft portion 11 formed so as to be able to be inserted into the cylindrical portion 7 without much play, and an open end of the shaft portion 11. And a head 12 having an outwardly extending flange portion extending vertically. The pin 5 is fixed to the wall material 1 by screwing a tapping screw 13 inserted into a mounting hole provided in an outward flange portion of the head 12 into the back surface of the wall material 1.

The procedure for mounting the wall material mounting structure thus constructed will be described below. First, the pin 5 is fixed to the back surface of the wall material 1 as described above, and the grommet 4
Is inserted into the C-shaped groove 3a of the rail member 3 as shown by the arrow A in FIG. The length between the outer surfaces of the cylindrical portion 7 in the up-down direction can be inserted through the opening of the groove 3a and is substantially equal to the opening width. Therefore, when the cylindrical portion 7 is inserted into the groove 3a, the engaging claw 9a abuts on the inward flange portion 3b of the rail member 3, but the flexible leg piece 9 is elastically deformed inward, and The engagement claw 9a can dodge the inward flange 3b of the member 3.

Further, when the grommet 4 is pushed in until the left and right walls of the head 6 come into contact with the surface of the inward flange 3b of the rail member 3, the engagement claws 9a are completely inserted into the grooves 3. As shown in FIG. 3, the flexible claw 9a engages with the back side of the edge of the inward flange portion 3b behind the opening edge of the groove 3a of the rail member 3, The grommet 4 is retained and temporarily fixed.

Next, the shaft 11 of the pin 5 fixed to the wall material 1 is moved to the grommet 4 as shown by an arrow B in FIG.
Through the opening 8 in the cylindrical portion 7. Note that the outer shape of the shaft portion 11 is formed to such an extent that it can be fitted into the cylindrical portion 7. Therefore, when the shaft 11 is pushed in, the shaft 11
The inwardly projecting portions 9b of the flexible leg pieces 9
And the two flexible leg pieces 9 are pushed outward, so that the engagement state of the engagement claw 9a is reliably maintained.

Thus, the wall member 1 is attached to the rail member 3 on the aggregate 2 side. As described above, since the grommet 9 is attached by engaging the engagement claw 9a with the inward flange portion 3b of the rail member 3, the grommet 9 can be moved in the axial direction of the rail member 3. Therefore, even if there is a gap between the adjacent wall members 1 or even after being attached to the aggregate 2 side, the adjustment can be easily made, and it is not necessary to fill the joint with putty as in the conventional example. In addition, the shaft portion 11 can be displaced with respect to the axial direction of the tubular portion 9, and the front and rear direction of the aggregate 2 can be adjusted.

Further, since only the shaft portion 11 is inserted and fitted into the cylindrical portion 9, the grommet 4 and the pin 5 can be easily separated by peeling off the wall material 1, It is possible to use a clip composed of both of them repeatedly.

[0016]

As described above, according to the present invention, the tubular portion of the grommet is inserted into the groove on the aggregate side, and the engaging claw of the flexible leg is engaged with the edge of the groove on the aggregate side. To temporarily fix the grommet
The wall material is attached to the aggregate by inserting the pin of the pin fixed to the wall material into the cylindrical part of the grommet, and the rivets and screw heads are exposed on the surface of the wall material There is no need to fill with putty,
The work of attaching the wall material can be simplified . Also , the shaft of the pin can be removed from the cylindrical portion of the grommet, and the pin and the grommet can be used repeatedly.
Further, a rail member having a C-shaped cross section is fixed to the aggregate, and a grommet is engaged with the groove having the C-shaped cross section, whereby the wall material can be displaced in the axial direction of the rail member. Since the position of the joint between the adjacent walls can be adjusted even after attaching the joint, the work of burying the putty on the joint is not required, and the attaching workability can be further improved.
