Next, an adiabatic double roof apparatus A using the roof mounting apparatus B will be described with reference to FIG. In addition, this embodiment is an example in which a protruding portion (described later) of the inner roof plate has a hat structure.

This heat-insulating double roof apparatus A has an inner roof plate 10
0 and an outer roof board 200 have a double structure, and each roof board 100, 200 has a heat insulating material 1 such as glass wool.
01 and 201 are lined, and the heat insulating materials 300 and 300 are doubly stacked and loaded in the space between the roof plates 100 and 200.

A panel receiving frame 410 having a hat-shaped cross-section is attached to a base material 400 such as a purlin or a beam by a fastener 4.
It is fixed by using 11. Panel receiving frame 41
A frame 420 having the same shape as the frame 60 described with reference to FIGS. 1 to 3 is fixed to the top of 0. On the other hand, the left and right inner shingles 100, the rising portions 110 at the ends of the 100,
The folded-back portions 120, 120 are formed at the upper end of the 110, and these folded-back portions 120, 120 are engaged with the frame 420 from both the left and right sides of the panel receiving frame 410. The left and right rising portions 110, 110 are covered with the cap 130, and the engaging portion 131 of the cap 130 is provided on the rising portion 110.
1 is engaged. The inner roof boards 100, 10 described above
A protrusion portion M having a hat-shaped structure is formed by the connecting portions of 0s.

In the temporarily mounted roof mounting device B, the leg plates 45, 45 of the pair of holding tools 40, 40 are fitted onto the projecting portion M from above, and then the tightening tool 50 is tightened. By such tightening of the fasteners 50, the projecting portions M are firmly held by the leg plate portions 45, 45 facing each other, and the supporting body 20 is provided above the projecting portions M in a protruding manner. Also,
When the projecting portion M is held by the leg plate portions 45, 45, the folded-back piece portions 46, 46 of the leg plate portions 45, 45 cause the cap 130 to move.
There is a case where it is pressed against the engaging portion 131 or a portion in the vicinity of the engaging portion 131, and the engaging piece portion 47 of the leg plate portions 45, 45,
48 and the like are also pressed against the cap 130.

Pressure contact of these portions, especially the locking piece portion 47,
By the pressure contact of the cap 48 with the cap 130, the roof plate attachment device B is less likely to slip on the protrusion M, and the top roof plate 200 is prevented from slipping off. In order to improve such a slip prevention effect, as shown in the circle in FIG.
It is effective to form sawtooth portions 46a, 47a, 48a on the respective tip edges of the folded-back piece portion 46 and the locking piece portions 47, 48. By doing so, the tightening of the tightening tool 50 is performed. The saw teeth 46a, 47a, and 48a are cap 13 by the force.

The foamable rubber sheet 81 is attached to the rear surface of the leg plate portion 45 as shown by the phantom line in FIG. 2 to improve the workability. Further, the engagement piece portion 42 and the contact plate portion 44 are attached to the body portion 23.
If a gap serving as a tightening margin is formed between the flange portion 24 and the mounting plate portion 41 when they are overlapped with each other, the tightening force of the tightening tool 50 causes the folding piece portion 46 and the locking piece. Part 47,
Effectively transmitted to 48, a strong holding state is obtained. When the anti-slip action is ensured as described above, there is no room for moisture to enter the room because the cap 130 does not have a hole that causes moisture to enter. Further, as shown in FIG. 5, when the set screw 80 is screwed into the cap 130 by utilizing the screw insertion hole 49 of the leg plate portion 45, a more remarkable anti-slip action is exhibited. Therefore, this method can be suitably applied to a steep roof.

Standing portions 210, 210 are also formed at the end portions of the left and right outer roof boards 200, 200, and folding portions 220, 220 are formed at the upper ends of the rising portions 210, 210. These folded-back portions 220, 220 are formed on the frame 6 from the left and right sides of the support body 20 of the roof plate attachment device B.
0 ridges 63, 63 are engaged. And the clip 24 with which the rising parts 210, 210 are covered
It is clamped at 0, the cap 230 is put on the left and right rising portions 210, 210 from above the clip 240,
The engaging portion 231 of the cap 230 is the rising portion 21.
It is engaged with the lower end of the stepped portion 211 or the clip 240 provided on the No. 0.

According to this adiabatic double roof apparatus A, the support 20 made of synthetic resin is provided in the heat transfer path connecting the frame 60 contacting the outer roof panel 200 and the leg plate section 40 contacting the inner roof panel 100. Since it is interposed, a metal heat transfer path that connects the outer roof panel 200 and the inner roof panel 100 is not formed. Therefore, the outside of the outer shingles 200 and the inner shingles 10
There is no possibility that dew condensation will occur on the surface of the heat-insulating double-roof apparatus A due to the temperature difference between the inside and the inside of 0, and the heat transfer inside and outside the heat insulating double-roof apparatus A is extremely unlikely to occur.

Further, in the above construction, it is possible to construct the heat insulating double roof apparatus A without using the height adjusting member 22 of the supporting body 20. That is, when the height adjusting member 22 is not used, the frame 60 is attached using the recess 26 and the positioning hole 28 of the body portion 23 in the base 21, and the folded portion 22 of the outer roof panel 200 is attached to the frame 60.
0, 220 are engaged, and the rising portion 22 is fixed by the clip 240.
0 and 220 may be sandwiched and the cap 230 may be put on the top. In this way, an adiabatic double roof device with a narrow gap between the inner roof panel 100 and the outer roof panel 200 is constructed.

FIG. 6 shows a roof plate mounting device B according to another embodiment.
The heat insulation double roof apparatus A using is shown. The difference between this embodiment and the embodiment shown in FIG.
Nos. 0 and 100 are fastened together by way of the suspension 500, and the fastened joint is formed as the protrusion M of the inner roof board 100. The point is that a bottom plate portion 46a is formed on the side surface of the protrusion M. According to this one, the fastener 50
By tightening (see FIG. 1), the left and right bottom plate portions 46a, 4a
6a grips the protruding portion M so that the supporting body 20 projects above the protruding portion M. Also in this embodiment, the same effect as that of FIG. 5 is obtained. Since other points are the same as those in FIG. 5, the same portions are denoted by the same reference numerals and detailed description thereof will be omitted.

[0031]

INDUSTRIAL APPLICABILITY The roof panel mounting device of the present invention has a novel shape and structure, and is compactly assembled or temporarily assembled, so that it is provided for each connecting portion between the inner roof panel and the outer roof panel. Independently, there is no member like the conventional long frame that obstructs the work of spreading the heat insulating layer between the inner roof plate and the outer roof plate, and it has better storability and transportability than before.
Furthermore, the handling is greatly improved. Also, by properly selecting the shape of the leg plate part of the holding tool, it becomes possible to deal with whether the protruding part of the inner roof plate has a hat-type structure or a crimping structure, and that is the general purpose. The property is improved. Further, the frame and the holding tool are insulated by a heat insulating support made of synthetic resin or the like.

The heat-insulating double roof device constructed by using the above roof plate attaching device has good workability and holds the protruding portions of the outer roof plate and the inner roof plate which are attached to the frame of the roof plate attaching device. Since the holding tool is insulated by the support made of synthetic resin, the outer roof plate and the inner roof plate are not connected by the heat transfer path of the metal, and there is no risk of dew condensation on the inner surface of the inner roof plate. Since heat does not easily move inside and outside the heat insulating double roof device, the overall heat insulating performance of the heat insulating double roof device is significantly improved as compared with the conventional one.
