[0011]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 5 show one embodiment of the present invention.

1 to 5, reference numeral 1 denotes an existing corrugated slate plate roofing material, which is fixed to a purlin 3 having a U-shaped cross section by an existing hook bolt 2. That is, the hook bolt 2 penetrates the corrugated slate board roofing material 1, and the hook portion 4 at the lower end is locked to the edge of the purlin 3. Further, the thread portion 5 at the upper end of the hook bolt 2 is provided with a packing 7 having a circular shape in plan view, which is sequentially provided on the crest 6 of the slate roofing material 1.
And a nut (first
Nut 9). In this embodiment,
A hexagon nut is used as the first nut 9.

Reference numeral 10 denotes a clamp used for fixing a new metal plate roofing material 20 above the slate plate roofing material 1 so as to cover the slate plate roofing material 1. The clamp 10 is made of, for example, metal.

The clamp device 10 is composed of an upper and lower two-stage bolt body having a hat-shaped fitting portion 11 and a sword tip portion 12 erected from the center of a top surface 11a of the fitting portion 11. The outer surface of the sword tip 12 has a male screw 12a.

The fitting portion 11 has a lower opening 13 large enough to receive the first nut 9.
Has an accommodation space S formed therein, which can accommodate the upper end screw portion 5 upward, and has several vertical slits 14 formed from the lower opening 13 side toward the accommodation space S side. Further, the accommodation space S of the fitting portion 11
A meshing portion 15 that meshes with the upper end screw portion 5 is formed therein.

The lower opening 13 is formed by an outward flange 16. This outward flange 1
6 has a shape corresponding to the hexagonal shape of the first nut 9. The outer surface of the fitting portion 11 has a male screw 11b in a region from the upper surface f of the outward flange 16 to the top surface 11a.

Further, as shown in FIGS. 3A and 4, before the setting, the fitting portion 11 is in a divergent state, and the upper end screw portion 5 and the hook bolt 2
When the first nut 9 is accommodated from above, the first nut 9 is set to a size that can be easily accommodated in the accommodation space S and the lower opening 13, respectively. That is, the diameter of the lower opening 13 that is the nut 9 housing portion is larger than the outer diameter of the nut 9. The inner diameter of the accommodation space S is at least larger than the outer diameter of the upper end screw portion 5 up to the position D (see FIG. 1) of the fitting length d of the upper end screw portion 5 of the hook bolt 2.

In this embodiment, the meshing portion 15 that meshes with the upper end screw portion (male screw) 5 is a female screw.
In the present invention, the male screw 5
A female screw other than the female screw screwed into the connector can be used. In short, it is sufficient if it has a configuration that meshes with the peaks and valleys of the upper end screw portion 5.
Rough surfaces, groove shapes, etc. can also be adopted.

Reference numeral 18 denotes a second nut screwed into the male screw 11b formed on the outer surface of the fitting portion 11.

As shown in FIG. 2, a large number of fixed clamps 10 are mounted on a newly-installed metal sheet roofing material 20 such that the peaks 20a thereof are superimposed on the top surface 11a of the clamps 10. Place.

At each overlapping portion, the sword tip portion 12 is inserted into the metal sheet roofing material 20, and the washer 3 is placed on the mountain portion 20a.
The metal plate roofing material 20 is fixed to the slate plate roofing material 1 by screwing the nut 38 into the sword tip portion 12 with the 6 and the packing 37 interposed therebetween.

As shown in FIG. 3 (A), the upper end screw 5 and the first nut 9 of the hook bolt 2 are covered with the clamp 10 from above the upper end screw 5, and then, as shown in FIG.
As shown in (B), the clamp 10 is fastened to the upper end thread 5 using the second nut 18. In this case, since the inner surface 16a of the outward flange 16 has a shape corresponding to the hexagonal shape of the first nut 9, even if the second nut 18 is rotated in the direction shown by the arrow G, the clamp is performed during this rotation. The situation where the tool 10 rotates can be avoided. That is, in this embodiment, the clamp 10 has a rotation preventing function. In addition, even if the inner surface 16a of the outward flange 16 is not formed in a hexagonal shape, the outward flange 16 is formed into a shape having a corner that is caught by the corner 9a of the first nut 9 when the second nut 18 is turned. Even if the inner surface 16a is formed, the clamp member 10 can exhibit the rotation preventing function. Further, even if the rotation preventing function is not provided, the clamp 10
The clamp tool 10 can be tightened to the upper end screw portion 5 even when the second nut 18 is turned while holding from outside by hand or the like.

In this embodiment, the clamp 10
Although a metal member is used as the material, the clamp member 10 may be made of a strong synthetic resin. In this case, a heat insulating effect can be expected by providing a heat insulating member between the metal plate roofing material 20 and the slate plate roofing material 1.

As described above, the ridges 6 of the slate shingle 1
When the clamp tool 10 is interposed between the ridge 20a of the metal sheet roof material 20 and the clamp tool 10, the slate plate roof material 1 is cracked because the clamp tool 10 is fitted from above the upper end thread portion 5 of the hook bolt 2. There is no danger.

As shown in FIG. 3 (A), the upper end screw portion 5 and the first nut 9 of the hook bolt 2 are covered with a clamp 10, and subsequently, as shown in FIG. 2
Since the clamp tool 10 is tightened to the upper end screw portion 5 using the nut 18 of the above, even when a tensile force is generated at the time of negative pressure,
There is no possibility that the clamp 10 will come off.

Further, even if a force acts on the metal sheet roofing material 20 due to snow or the like, there is no possibility that the clamp 10 will come off.

[0028]

As described above, according to the present invention, the upper end screw portion of the hook bolt and the first nut of the hook bolt are covered with the clamp, and the clamp is tightened to the upper end screw using the second nut. The construction can be simplified. Also, the slate shingle roof material does not crack and the clamp does not come off.
