Description of the Related Art Conventionally, in order to support a ceiling below a roofing material 2a installed along a roof having a large slope, as shown in FIG. 9, a hanging screw is attached to a purlin 11 which supports the roofing material 2a. The rod 8a is vertically welded, and the vertically elongated hanging metal fitting 12 is attached to the hanging screw rod 8a.
The ceiling base 9 assembled in a grid pattern in 2 is suspended and held, and the ceiling material 10 is attached to the ceiling base 9. In such cases,
The hanging screw rod 8a is bent to support the ceiling material 10 substantially horizontally.

[0003]

However, in such a structure, the strength of the roof material 2a is sufficiently strong to use the roof material 2a having the metal roof plates m, m attached to the front and back sides. Therefore, the space between the purlins 11 for supporting the roof material 2a may be widened, but when the ceiling material 10 is supported, the supporting strength of the ceiling material 10 is insufficient between the purlins 11 and 11, so that Conventionally, as shown in FIG. 9, the hanging screw rod 8a is also welded to the purlin 11a in the middle of the purlins 11 and 11 to attach the hanging metal fitting 12 and the ceiling metal 9 to the hanging metal fitting 12 as shown in FIG. The ceiling material 10 is suspended and held.

In order to suspend the ceiling material 10,
There is a problem that a troublesome welding work is required on the back surface of the roof material 2a, and the workability is reduced. Further, since the hanging screw rods 8a ... Are all bent to make the ceiling material 10 substantially horizontal, there is a problem that the bending work is troublesome and the workability thereof is further lowered. The present invention is intended to solve such a problem, and an object of the present invention is to provide a ceiling support structure capable of enhancing workability for ceiling support while supporting the ceiling with high strength. To do.

[0005]

According to the present invention, a nut cylinder 3 is suspended from a lower end portion of a support member 7 penetrating a roofing material 2a installed along a roof and is hung on the nut cylinder 3. Screw rod 8
Is a support structure for the ceiling in which the ceiling material 10 is supported by the hanging screw rod 8 via the mounting means X.
Is pierced substantially vertically with respect to the roof material 2a, and a bendable portion U is detachably formed in the middle of the hanging screw rod 8.

The support 7 is provided with a nut cylinder 3 having an internal thread on the inner surface at the lower end of the threaded rod 1, and a nut 4 is screwed on the head of the threaded rod 1. A retaining blade 5 that is screwed and is inserted under the nut 4 to expand its diameter by receiving the pressure of the nut 4, and a step portion that prevents the retaining blade 5 from moving downward in the screw rod portion 1. 6 is formed and configured.

[0007]

The ceiling material 10 is suspended from the lower end of the supporting member 7 penetrating the roof material 2a through the mounting means X to improve the workability and support the ceiling material 10 with sufficient strength. Then, in the bendable portion U, the middle portion of the screw rod portion 1 is easily bent with respect to the support tool 7 that penetrates the roof material 2a substantially vertically, and supports the ceiling material 10 substantially horizontally. The construction for supporting the ceiling material 10 substantially horizontally is easily performed. Greatly improves workability.

Further, the support member 7 is penetrated through the roof member 2a,
Tighten the nut 4 and increase the diameter of the retaining blade 6 to prevent retaining. Suspended screw rod 8 on nut cylinder 3 hanging on support 7
Install by screwing in. The hanging metal member 12 is attached to the hanging screw rod 8 to support the ceiling material 10 and enhance the support strength of the ceiling material 10. In particular, the attachment of the support 7 can be performed from the upper surface side of the roof material 2a, that is, the fixing operation with a so-called one-way bolt, and the attachment of the support 7 to the roof 2a can be easily performed.

[0009]

EXAMPLE As shown in FIG. 3, the roofing material 2a is, for example,
A heat insulating material layer 14 made of a foamed synthetic resin is sandwiched between the color-coated front and back metal plates 13, 13. Thick portions 15 and 16 are formed at both ends of the roof material 2a in a direction substantially orthogonal to the eaves ridge direction. The thick portion 15 on one side is slightly wider than the thick portion 16 on the other side, and the metal plate 13 on the surface is extended to the thick portion 16 on the other side to form the connecting piece 17 over the entire length. . Further, a thick mountain portion 19 is also formed in the middle portion of the roof material 2a. Then, the connection concave portion 20 is formed on the bottom surface on the side where the connection piece 17 is formed, and the connection convex portion 21 is formed on the bottom surface on the other end side. Then, as shown in FIG. 6, the roof members 2a, 2b are connected to the connection recess 20 and the connection protrusion 21 in a direction substantially orthogonal to the eaves ridge direction, and the connection piece 17 is connected to the thick portion 15 on one side. The roof members 2a and 2b can be connected and engaged with each other to make a roof. The packing 22 is interposed at the connection point. The design of the roof material 2a can be changed in various ways.

The roofing material 2a is provided with metal plates 13 and 13 on the upper and lower sides and has sufficient strength.
Purlins 11, 11 on which a is mounted have a relatively wide interval L. And the roof slope so constructed is 3
/ 100 or more. Then,
The self-drilling bolt B is screwed into the mountain portion 19 of the roofing material 2a, penetrates the roofing material 2a and is 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 a vertically elongated substantially C-shaped hanging fitting 12 as a mounting means X is attached to the hanging screw rod 8 with nuts 23, 23. The hanging screw rod 8 is bent, and the hanging metal fitting 12 suspends and supports the ceiling substrate 9 assembled in a lattice shape, and the ceiling material 10 is fixed to the ceiling substrate 9.

By the way, the interval L between the purlins 11 and 11 is wide, and the interval between the hanging screw rods 8 and 8 welded to the purlin 11 is also wide, so that the strength for supporting the ceiling material 10 is insufficient. Supporting strength is supplemented in a simple structure.
This configuration will be described in detail. As shown in FIG. 4, the roof material 2a
At one end of the threaded rod portion 1 that is inserted into the nut barrel 3, a nut tube body 3 having a female thread on its inner surface is crimped at the crimp portion K, and is attached and hung down. A nut 4 is screwed onto the head of the threaded rod portion 1 so as to be freely threaded. Below the nut 4, a diameter-increasing moving body 24 with a flange is movably inserted into the screw rod portion 1. A packing 25 is attached to the back surface of the flange 27, the diameter-expanding moving body 24 is made of synthetic resin, and a taper portion 26 is formed at the lower end thereof.
Further below the diameter-expanding moving body 24, a metal retaining blade 5 is provided.
Is inserted into the screw rod portion 1, and the retaining blade 5 is attached to the screw rod portion 1.
It is designed so that it cannot be received further by the receiving step portion 6 formed in the above and further moved downward.

Thus, as shown in FIG. 1, the screw rod portion 1 is vertically inserted together with the nut cylinder 3 between the purlins 11 and 11 with respect to the roof material 2a which is installed at a large slope.
Then, by screwing the nut 4 screwed into the threaded rod portion 1, the diameter-expanding moving body 24 provided with the flange 27 is pressed and moved downward, and the tip end portion of the diameter-expanding moving body 24 made of synthetic resin. While the crushing occurs, the retaining blade 5 is expanded in diameter on the lower surface of the metal plate 13 on the front surface, and the flange 27 having the packing 25 on the back surface, the retaining blade 5 and the movable body 24 for expanding diameter are expanded.
And the crushed part of the other roof material 2a through the packing 25
Of the metal plate 13 on the surface of the roof and the connecting piece 17 of the other roofing material 2b
The hanging bolt A is fixed to the roof material 2a so as not to be detachable. Thus, the nut cylinder 3 can be attached by an operation from one direction of screwing the nut 4. Then, as shown in FIG. 2, a screw portion body 31 having an annular portion 30 is screwed into the nut tubular body 3, and a hook 33 having a nut tubular portion 32 is hooked and connected to the annular portion 30 so as to be bendable. Without nut 32
The threaded rod 34 is screwed onto the threaded rod 34 to form the bendable portion U in the middle of the hanging threaded rod 8. Then, the vertically elongated substantially C-shaped hanging fitting 12 as the attachment means X is attached to the threaded rod 34 of the hanging threaded rod 8 with the nuts 23, 23.
It is fixed at. Then, the ceiling base 9 is suspended and supported by such a suspension fitting 12. In this way, the supporting strength of the ceiling base 9 is increased. Then, a cap 29 is screwed and attached to the tip of the threaded rod portion 1 for waterproofing and enhancing the design.

FIGS. 7 and 8 show another embodiment of the bendable portion U, and the structure of the bendable portion U can be variously changed in design.

As described above, according to the present invention, since the ceiling material is attached to the lower end portion of the rod-shaped support tool penetrating the roofing material installed through the attaching means, the support penetrating the roofing material is provided. The ceiling material can be hung and held at the lower end of the fixture via the attachment means,
While improving the workability and supporting the ceiling material with sufficient strength, the support tool penetrates almost perpendicularly to the roof material, and the foldable part is removable in the middle of the hanging screw rod. Since it is formed, the middle part of the screw rod portion in the bendable portion easily bends with respect to the support tool that penetrates substantially perpendicularly to the roof material, and the ceiling material can be supported substantially horizontally. There is an advantage that construction can be performed easily and workability can be significantly improved.

Further, in the supporting tool, a nut cylinder body having an internal thread cut on the inner surface is attached to the lower end portion of the threaded rod portion, and the nut is threadably engaged with the head portion of the threaded rod portion to form a nut. A retaining blade that expands in diameter by being pressed by the nut is inserted below, and a receiving step portion that prevents the retaining blade from moving downward is formed in the screw rod portion. Penetrate the support through the roof material, tighten the nut to prevent the blade from expanding,
It is possible to attach the hanging screw rod to the nut cylinder that hangs down on the support tool by screwing it in, and attach the hanging metal fitting to this hanging screw rod to support the ceiling material. Increased strength, especially the support fixture can be attached from the top side of the roof connecting point, so-called one-way bolt fixing operation, and the support fixture can be attached to the roof easily. The advantage is that
