BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a renovated roof in which a new shingle is laid on an existing shingle.

[0002]

2. Description of the Related Art A modified roof structure of this type is disclosed, for example, in Japanese Patent Publication No. 7-74524. As shown in FIG. 4, a new roof plate 5 made of a folded plate is attached via a tight frame 20 on an existing roof plate 1 made of a slate corrugated sheet laid on a main building 2 as shown in FIG. The tight frame 20 is the existing roof panel 1
Each tight frame 20 is fixed with a fixing tool 21 so as to straddle one ridge of the existing shingle 1. The new roof slab 5 engages and fixes the ridges 22 on both side edges thereof at regular intervals on the adjacent tight frames 20, and forms the valleys 23 provided at the intermediate portions thereof on the valleys of the existing roof slab 1. It is supported in contact with the portion 24.

[0003]

However, in the above-mentioned conventional renovated roof, the middle valley 23 of the new shingle 5 is brought into contact with the valley 24 of the existing shingle 1, so that the new The treading pressure of the builder, the temporary placing load of the members required for the construction, or the snow load is concentrated on the contact portion between the valley 23 of the new shingle 5 and the valley 24 of the existing shingle 1. As a result, the existing shingle 1 was easily damaged or deformed, and in particular, the existing shingle 1 made of slate was easily broken.

[0004] The present invention has been made in view of such a problem, and an object of the present invention is to provide a renovated roof capable of improving the load-bearing capacity of a new roof shingle and preventing damage to an existing roof shingle. .

[0005]

According to the present invention, there is provided an existing roof slab comprising a slate corrugated sheet fixed on a roof base material.
In a renovated roof in which a new roof shingle made of folded plates is laid via a roof receiving frame, the roof receiving frame has at least two peaks of the existing roof shingle between the existing roof shingle and the new roof shingle. A horizontal plate portion having a length capable of covering the roof plate; and a lower portion formed at both ends of the horizontal plate portion so as to be bent downward in a U-shaped cross section and placed on a valley portion of the existing roof plate and the roof plate together with the existing roof plate. A pair of fixed legs fixed on the base material with fasteners, and a new roof panel connected to the upper ends of the outer leg pieces of each fixed leg so as to be higher than the fasteners fixing the existing roof panel. And a new roof plate stop portion of the adjacent roof receiving frame is overlap-bonded between the adjacent new roof plate frames via a hook, and the seam fasteners at the ends of the adjacent new roof plate are connected to each other by the hook. Is characterized by being fastened to the upper end of

[0006]

The new roof shingle is received and supported on the horizontal plate between the pair of fixed legs of the roof receiving frame.
Therefore, the new roof slab can sufficiently withstand the treading pressure of the builder, the temporary placing load of the construction members, or the snow load during this construction. In addition, the new shingle does not directly contact the existing shingle, so that there is no damage or deformation. Since the roof receiving frame is continuously and stably mounted and fixed on the existing shingle, even if the existing shingle is a slate corrugated sheet, it is not easily broken, and new roofing work can be easily performed. In addition, the fastener that fixes the existing roofing plate can be easily installed because the roof receiving frame can be attached as it is without cutting off the head thereof.

[0007]

1 to 3 show an embodiment of a renovated roof according to the present invention. Reference numeral 1 denotes an existing roof plate made of a slate corrugated sheet, a folded plate, or the like, which is laid on a roof base material 2 such as a purlin or a beam, and fixed with a stopper 3 having a head 3a such as a hook bolt or a channel bolt. ing. At the time of repairing the existing shingle 1, a plurality of roof receiving frames 4 are placed on the existing shingle 1 in a horizontal direction parallel to the roof base material 2 and a new shingle 5 is laid. .

The roof receiving frame 4 is formed by bending a strip-shaped metal plate to form a horizontal plate 7 having a length capable of covering at least two peaks 1 a of the existing roof plate 1. It is formed in a left-right symmetrical shape having a pair of U-shaped fixed legs 8 continuously bent at the left and right ends. The fixed leg 8 bends the inner leg 8a obliquely downward from the end of the horizontal plate 7 and connects the lower end of the inner leg 8a to the existing roof plate 1.
A curved lower end portion 8b is continuously provided by bending in an arc shape along the curved surface of the valley portion 1b, and further, the outer leg piece 8c is formed from the curved lower end portion 8b.
Extends obliquely upward. At the upper end of the outer leg piece 8c, a new roof plate stopper 9 having a U-shaped cross section is continuously provided. The newly installed roof plate stopper 9 has an outward horizontal portion 9a which is bent horizontally outward from the upper end of the outer leg piece 8c, and an upright portion 9b which is bent substantially perpendicularly upward from the outer end of the outward horizontal portion 9a. And an inward horizontal portion 9c horizontally bent inward from the upper end of the upright portion 9b.
And The outward horizontal portion 9a is formed at a position higher than the horizontal plate portion 7. Bolts 13 to be described later are provided on the upright portions 9b.
Are provided (not shown). Note that the entire surface of the horizontal plate portion 7 does not necessarily have to be horizontal, and a concave groove may be formed at an intermediate portion thereof.

In the roof receiving frame 4, the curved lower ends 8b of the left and right fixed legs 8, 8 are placed along the surface of the valley 1b of the existing roof plate 1, and the roof together with the valley 1b. Base material 2
The horizontal plate portion 7 is attached to the existing roof plate 1 so as to float above the existing roof plate 1 through a space by fixing the horizontal plate portion 7 with a stopper 11 such as a self-drilling screw. Similarly, the adjacent roof receiving frame 4 is placed and fixed on the existing shingle 1. At this time, the uprights 9b and 9b of the new roof plate stoppers 9 and 9 of the adjacent roof receiving frames 4 and 4 above the ridges 1a of the existing roof slab 1 are provided with the suspenders 12 between the mating surfaces thereof. Bolt 1 to be interposed and passed through the suspender 12 and the upright portion 9b
3 and nut 14. Thus, the existing shingle 1
The roof receiving frame 4, which is mounted and fixed on the roof base material 2 continuously in the left-right direction parallel to the roof base material 2, is mounted and fixed not only at one location in the roof gradient direction but also at several locations.

The new roof panel 5 is formed in a groove shape in cross section.
Each of the side plates has a flat bottom plate portion 5a having a width longer than the length of the horizontal plate portion 7 of the roof receiving frame 4, and side plate portions 5b, 5b bent obliquely upward from both left and right ends of the flat bottom plate portion 5a. At the upper end of the portion 5b, a fastening piece 5c is continuously provided via an outward horizontal portion 5d. This new shingle 5 is fitted with the seam 12 together with the seam 5c of the adjacent new shingle 5 so as to cope with the roof slope above the existing shingle 1. It is laid that way. At this time, the outward horizontal portion 5d of the new roof panel 5 is received and supported on the inward horizontal portion 9c of the roof receiving frame 4.

In the new roof plate 5, the flat bottom plate portion 5a occupying most of the plate width direction contacts the upper surface of the horizontal plate portion 7 of the roof receiving frame 4, or a gap (about 10 mm) as shown in FIG. It is laid to form. Therefore, at the time of rehabilitation work, even when walking on the already-covered new shingle 5 or temporarily placing construction members such as a seaming machine required for construction, the new shingle 5 is fixed by the left and right fixed legs 8. Horizontal plate 7 of roof receiving frame 4 supported at two points on valley 1b of existing roof plate 1
Since it is firmly received and supported, it can sufficiently withstand the treading pressure and the temporary placing load, and also has excellent load bearing capacity against snow. Since the new shingle 5 does not directly contact the existing shingle 1, the existing shingle 1 is not damaged or deformed. In addition, the roof receiving frame 4 arranges the horizontal plate portion 7 in a floating state above the existing roof plate 1 and places the curved lower end portions 8b of the left and right fixed legs 8 on the surface of the valley portion 1b of the existing roof plate 1. Since it is fixed via the stopper 11 after being brought into surface contact, it is possible to prevent the existing roof slab 1 from being damaged by applying a concentrated load or being deformed. Adjacent new shingles 5 are fastened to the hooks 12, so there is no need to drill holes in the new shingles 5 as in the construction method of stopping the edges of the new shingles 5 with bolts or the like. No leakage,
Further, a cover or a bolt for closing the hole is not required, and the number of construction steps and the number of members can be reduced. Since the roof receiving frame 4 is formed bilaterally symmetrically, there is no left-right directionality and the construction is easy. It should be noted that the lower end 8b of the roof receiving frame 4 has a smaller curvature than the waveform of the valley 1b of the existing roof slab 1 made of a slate corrugated sheet.
Of the existing roof shingle 1
Even if there is a dimensional error between b and 1b or a dimensional error of the roof receiving frame 4, the roof receiving frame 4 may be sufficiently fixed to the valley 1b.

[0012]

According to the present invention, the new shingle is stably received and supported by the horizontal plate portion of the roof receiving frame.
The new shingle can sufficiently withstand the treading pressure of the builder, the temporary placing load of the construction members or the snow load, and does not damage or deform the existing shingle. Since the roof receiving frame is continuously and stably placed on the existing roof shingle, the existing roof shingle is less likely to break when the roof receiving frame is fixed, making it easy to construct a new roof shingle and has excellent workability. . further,
Adjacent new shingles can be firmly tightened in response to a change in the roof slope through the suspension, and are superior in waterproofness and workability as compared with bolting and the like. In addition, since the roof receiving frame can be attached without cutting the head of the fastener that fixes the existing roof panel, workability is good.
