DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG.
A heat-insulating material layer 14 made of foamed synthetic resin is interposed between the color-coated front and back metal plates 13 in a sandwich shape. Thick portions 15 and 16 are formed at both ends of the roofing material 2a in a direction substantially orthogonal to the eaves ridge direction. One thick portion 15 is slightly wider than the other thick portion 16, and the other thick portion 16 has a surface metal plate 13 extending therethrough to form a connection piece 17 over the entire length. . In addition, a thick mountain portion 19 is also formed in an intermediate portion of the roofing material 2a. A connection recess 20 is formed on the bottom surface on which the connection piece 17 is formed, and a connection protrusion 21 is formed on the bottom surface on the other end side. Thus, as shown in FIG. 1, the connection concave portions 20 and the connection convex portions 21 are connected to the roofing materials 2a and 2b in a direction substantially orthogonal to the eaves ridge direction, and the connection piece 17 is connected to the one thick portion 15 as shown in FIG. And the roof materials 2a and 2b can be connected and roofed. And the packing 22 is interposed in the connection place. The design of such a roofing material 2a can be variously changed.

The roofing material 2a is provided with metal sheets 13 and 13 along the top and bottom, and has sufficient strength.
The purlins 11, 11 on which a is mounted have a relatively wide interval L. Then, the self-drilling bolt B is screwed into the crest 19 of the roofing material 2a, penetrated through the roofing material 2a and screwed into the purlin 11, and the roofing material 2a is fixed to the purlins 11, 11. A hanging screw rod 8 is welded to the purlin 11, and the hanging screw rod 8 has a vertically long substantially C
The letter-shaped hanging bracket 12 is attached with nuts 23, 23. The hanging base 12 suspends and supports the ceiling base 9 assembled in a lattice shape, and the ceiling material 10 is fixed to the ceiling base 9.

By the way, the space L between the purlins 11 and 11 is wide, and the space between the suspension screw rods 8 and 8 welded to the purlin 11 is also wide and the strength for supporting the ceiling material 10 is insufficient. The support strength is supplemented in a simple configuration.
This configuration will be described in detail. As shown in FIG.
At the end of the threaded rod portion 1 which is inserted through the nut, a nut cylinder 3 having an internal thread cut on the inner surface thereof is caulked at the caulking portion K and is attached there. A nut 4 is screwed to the head of the threaded rod 1 so as to be able to advance freely. Below the nut 4, a diameter-enlarging moving body 24 with a flange is movably inserted through the screw rod portion 1. A packing 25 is attached to the back surface of the flange 27, the moving body 24 for diameter expansion is made of synthetic resin, and a tapered portion 26 is formed at the lower end thereof.
Further below the diameter expanding moving body 24, a metal retaining wing 5 is provided.
Is inserted through the screw rod portion 1, and the retaining wings 5 are
Is received by the receiving step 6 formed so as not to move downward any further.

Thus, as shown in FIGS. 1 and 2, the threaded rod 1 is inserted together with the nut cylinder 3 between the purlins 11 and at the connection points of the roofing materials 2a and 2b.
Then, by screwing the nut 4 screwed into the threaded rod portion 1, the diameter-enlarging moving body 24 provided with the flange 27 is pressed and moved downward, and the distal end portion of the synthetic resin-made diameter-enlarging moving body 24. While the crushing occurs, the retaining wing 5 is enlarged in diameter at the lower surface of the metal plate 13 on the front surface, the packing 27 is provided with a flange 27 provided on the rear surface, the retaining wing 5 is enlarged in diameter, and the moving body 24 for diameter enlargement.
And one of the roofing materials 2a via the packing 25
Surface of the metal plate 13 and the connection piece 17 of the other roofing material 2b
, And the suspension bolt A is fixed to the roof material 2a so as not to be retained. In this manner, the nut cylinder 3 can be attached by the operation of screwing the nut 4 from one direction. Then, the suspension screw rod 8 is screwed into the nut cylinder 3, and the vertically long substantially C-shaped suspension fitting 12 as the mounting means X is fixed to the suspension screw rod 8 by the nuts 23, 23. . Then, the ceiling base 9 is suspended and supported by such a suspension fitting 12. Thus, the supporting strength of the ceiling base 9 is increased. And
A cap 29 is screwed and attached to the tip of the threaded rod portion 1 to achieve waterproofness and enhance design.

FIG. 5 shows another embodiment.
The support member 7 is penetrated in the crest 19 of FIG. 3A, and the suspension fitting 12 as the attachment means X is attached to the suspension screw rod 8 screwed into the support 7 through the nuts 23, 23, though not shown. The hanging base 12 holds the ceiling base 9, and the ceiling base 9 is fixed with the ceiling material 10. By the way, in the embodiment, the support member 7 is configured by integrally providing the nut cylinder 3 with the screw rod portion 1.
The ceiling member 10 may be supported by such a single threaded rod via the mounting means X, and the shape and shape of the support 7 may be variously changed.

The present invention is also applicable to a ceiling support structure of each floor in a multi-storey house.
