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 metal plates 13 and 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. .
Further, a thick mountain portion 27 is also formed in the 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. 7, the connection concave portions 20 and the connection convex portions 21 are connected to the roof members 2a and 2b in a direction substantially orthogonal to the eaves ridge direction, and the connection piece 17 is connected to one thick portion 15 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 upper and lower sides and has sufficient strength.
The purlins 11, 11 on which a is mounted have a relatively wide interval L. Then, a self-drilling bolt B as shown in FIG. 1 penetrates the roof material 2a and is screwed into the purlin 11 at the mountain portion 27 of the roof material 2a.
It is fixed at 1. Suspended screw rod 8 in purlin 11
And a vertically long substantially C-shaped hanging bracket 12 as an attaching means X is attached to the hanging screw rod 8 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 hanging 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, the moving body 24 for diameter expansion provided with the flange 31
It is movably inserted in. A packing 25 is attached to the back surface of the flange 31, 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-enlarging moving body 24, a metal retaining wing 5 is inserted through the screw rod portion 1, and the retaining wing 5 is received by a receiving portion 6 formed on the screw rod portion 1. , So that it cannot move downward any further.

As shown in FIGS. 1 and 4, the screw rod portion 1 is inserted together with the nut cylinder 3 between the purlins 11, 11 and in the crests 27 of the roofing material 2a. By screwing the nut 4 screwed into the rod portion 1, the diameter-enlarging moving body 24 with the flange is pressed and moved downward, and the synthetic resin-diameter enlarging moving body 24 is crushed at its tip. The retaining wing 5 is enlarged in diameter at the lower surface of the metal plate 13 on the front surface, and the flange 31 having the packing 25 on the rear surface is provided.
The metal plate 13 on the surface of one roofing material 2a is sandwiched between the retaining wing 5 and the collapsed portion of the diameter-enlargement moving body 24 with the expanded diameter, and the suspension bolt A is attached to the roofing material 2a. It is fixed so that it cannot be pulled out. 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 attached to the suspension screw rod 8 by the nut 23.
It is fixed at 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.

As shown in FIG. 4A, a cap support 19 is sandwiched between the fixture 7 and the roofing material 2a. As shown in FIG. 4 (b), the cap support 19 is formed by connecting a holding metal 29 to the inverted hat-shaped metal fitting 28 so as to be substantially orthogonal. Metal fittings 28
Receiving pieces 28a, 28a are formed at both ends in the eaves ridge direction, and holding pieces 29a, 29a are formed on the holding metal fittings 29 at both ends in a direction orthogonal to the eaves ridge direction. The cap 30 has, for example, an arcuate cross-sectional shape as shown in FIG. 4 (a), and ear-shaped engaging pieces 30 a, 30 a folded at both ends in the width direction thereof use the elastic deformability of the cap 30. By elastically fitting, the cap 30 is externally connected to the plurality of cap support fittings 19. In this manner, the long cap 30 is fitted and connected to the cap support fittings 19 fixed in the fixture 7 to prevent rainwater from entering along the fixture 7 penetrating the roofing material 2a. It is.

FIGS. 5 and 6 show another embodiment.
The self-drilling screw B is penetrated in the middle peak 27 of the roofing material 2a, and is screwed into the roof foundation 1 to be fixed. Also in this embodiment, the cap support 19 is inserted and fixed to the self-drilling screw B. FIG. 7 shows still another embodiment, in which the above-mentioned fixing tool 7 is used at a connection point of the roofing materials 2a, 2b. In such a case, the diameter of the retaining wing 5 and the cap support metal 19, which are increased in diameter, are used. And connection piece 1
7 and the metal plate 13 of one roofing material 2a.

[0014]

As described above, according to the present invention, a cap support is sandwiched between a fixture and a roofing material, and a cap which is long in the direction of the eaves is externally connected to the plurality of cap supports. Therefore, by fitting and connecting a long cap to the cap support bracket fixed in the fixture, rainwater can be prevented from penetrating through the fixture that penetrates the roofing material,
Even if packing is used as a fixture, even if the packing deteriorates due to aging, it is possible to avoid rain leakage, a long cap can hide multiple fixtures, and a long cap is orderly Appearance can be made, in particular, a nut cylinder is suspended from the lower end of the fixture, and a hanging screw rod is screwed to the nut cylinder,
A nut is screwed into the head of the threaded bar so as to be able to advance freely, and a retaining wing that expands in diameter under the pressure of the nut is inserted below the nut. A receiving step portion for preventing movement is formed, and the ceiling material is attached to the hanging screw bar via the mounting means, so that the hanging screw rod is screwed into a nut cylinder hanging down at the lower end of the fixture, There is an advantage that the ceiling material can be suspended and held on the suspension screw bar via the mounting means, the workability thereof can be improved, and the ceiling material can be supported with sufficient strength. In addition, the connection operation using the fixing device can be performed by an operation from the upper surface side of the roofing material, that is, can be performed by the fixing operation using the one-way bolt, and there is an advantage that the fixing device can be easily attached.
Moreover, the metal sheet of the roof material is sandwiched between the retaining wings
A cap support with a flat part is exposed above the roof material
Retaining stopper that has been inserted through the wand and has been enlarged by the screw advance of the nut
The roof metal plate is sandwiched between the wing and the flat part of the cap support bracket.
Holding and holding the cap support bracket,
Roof with expanded retaining wings and flat portion of cap support bracket
Can firmly hold the metal plate of the material,
Cap holding bracket holding strength can be increased, resulting in
Externally fit long caps on multiple cap support brackets
To increase the mounting strength of the connecting cap.
And the cap support bracket has a flat
There is an advantage that the retaining mechanism can be enhanced.
