The folded roof plate 3 is formed by bending a metal plate such as a long steel plate, and as shown in FIG. Left and right inclined side plates 5, 5, fitting ribs 6 protruding outward from a middle part near the bottom of each inclined side plate 5, and horizontal plates horizontally connected outward from the upper end of the inclined side plates 5. And a hook-shaped fastening piece 8 provided at the outer end of the horizontal plate 7. The fitting rib 6 includes a rib upper surface plate 6a that is bent outwardly from a middle part of the inclined side plate 5, preferably at a substantially right angle,
The rib slope plate 6b is formed to have a V-shaped cross section having a rib slope plate 6b turned obliquely downward from the protruding end of the rib top plate, and the lower end of the rib slope plate 6b and the end of the valley bottom plate 4 have substantially the same gradient as the inclined side plate 5. Are connected to each other via a lower portion 9 of the inclined side plate.

As shown in FIG. 1, a tight frame 2 is formed of a metal plate such as a strip-shaped steel plate, and is fixed to a base material 1 of a roof by welding or the like. The upper frame 11 is connected to the left and right horizontally so as to be movable by a predetermined distance. The lower frame 10 includes a horizontal upper frame receiving plate portion 12 that floats from the base material 1, a gate-shaped rising portion 13 that rises from the center of the upper frame receiving plate portion 12, and left and right sides of the upper frame receiving plate portion 12. It is formed in a shape having seat plate portions 14, 14 continuously provided at both ends, and the seat plate portions 14, 14 are fixed on the base material 1 by polymerization.

The upper frame 11 receives the horizontal plate 7 of the folded roof plate 3, receives a horizontal top plate 15 disposed on the top 13a of the rising portion 13 of the lower frame 10, and the top plate 1
Folded shingle 3 is installed diagonally downward from the left and right ends of 5
The left and right inclined side plate portions 16 and 16 formed along the outside of the inclined side plate 5 and the lower ends of the left and right inclined side plate portions 16 and 16 are bent inward at substantially right angles, and the bent piece 17 and the inclined side plate are bent. The lower frame 10 is formed by extending the lower ends of the left and right bent pieces 17, 17 substantially horizontally inward with the left and right L-shaped cross-section projecting fitting sections 18, 18 formed by the lower end of the section 16. Left and right bottom plate portions 19, 19 placed on the upper frame receiving plate portions 12, 12. Left and right inclined side plates 1
At the center in the left-right direction of the top plate portion 15 connecting the upper end plate portions 6 and 16, a positioning piece 34 for determining the position of the fastening piece 8 at the end of the folded roof plate 3 is cut and raised, and welded or swaged. And so on.

As means for connecting the upper frame 11 to the upper side of the lower frame 10 so as to be movable in the left and right horizontal directions, as shown in FIG. A hole 20 is provided.
Use is made of a fastener 21 made of rivets, bolts, nuts, or the like, which passes through zero. The coupling 21 in the illustrated example is made of a rivet, and has a head 22 larger than the length of the long hole 20 in the short side direction formed at one end of the shaft portion 23. Square shaft portion 2 having a large diameter and loosely fitted in elongated hole 20
3a is provided. The coupling tool 21 has a long hole 20 from above the bottom plate 19 and a hole 24 formed in the upper frame receiving plate 12.
And crimp the tip 23b of the shaft 23 projecting to the lower surface side of the upper frame receiving plate 12. At this time, the diameter of the square shaft portion 23a is larger than the diameter of the hole 24 of the upper frame receiving plate portion 12, and the axial length of the square shaft portion 23a is formed slightly longer than the plate thickness of the bottom plate portion 19. So the upper frame 1
Flexibility is ensured between the long hole 20 of the bottom plate 19 and the coupler 21 so that the upper frame 11 can be horizontally moved in the left-right direction on the upper frame receiving plate 12 of the lower frame 10.

Next, the procedure for attaching the folded roof plate 3 will be described. The tight frames 2 are arranged on the base material 1 at predetermined intervals, and the right and left seat plate portions 1 of each lower frame 10 are arranged.
4 is fixed to the base material 1. As shown in FIG. 3, in a state where the upper frame 11 is stopped at the neutral position on the lower frame 10 (the state of the chain line M), the adjacent folded roof plates 3
The valley bottom plate 4 of one of the folded roof shingles 3 that is to be roofed earlier among the roof frames 3 is dropped into a valley on one side between the tight frames 2 and 2. With this drop, the rib 6 for fitting the folded roof plate 3
However, while sliding down on the inclined side plate portion 16 on one side of the upper frame 11 and horizontally moving the upper frame 11 on the lower frame 10 in the right direction R where the other folded roof plate 3 is covered, the inclined side plate portion The projection 16 is fitted and locked to the projection fitting portion 18 below the projection 16. Therefore, the fitting rib 6 of the one folded roof plate 3
Can be smoothly and smoothly fitted and locked to the protruding fitting portion 18 of the inclined side plate portion 16 on one side of the upper frame 11.

Next, as shown in FIG. 4, as the valley bottom plate 4 of the other folded roof plate 3 is dropped into the valley on the other side between the tight frames 2 and 2, the folded roof plate 3 is folded. Of the upper frame 11 slides down on the other inclined side plate portion 16 on the other side of the upper frame 11 to move the upper frame 11 in the opposite direction L.
To the original neutral position, and at the same time, the fitting rib 6 is moved downward to the projecting fitting portion 18 below the inclined side plate portion 16 on the other side.
Is fitted and locked. Therefore, the fitting state of the fitting rib 6 of one folded roof plate 3 and the protruding fitting portion 18 is ensured, and the fitting rib 6 of the other folded plate 3 is also mounted on the other side of the upper frame 11. It is possible to fit smoothly and easily and securely into the protruding fitting portion 18 of the inclined side plate portion 16 without difficulty.

Thus, the fastening pieces 8 of the folded roof shingle 3 attached in this manner are adjacent to each other as shown in FIG. 1 by fastening the fastening pieces 8 of the folded roof shingle 3 attached earlier. The folded shingles 3 and 3 are connected. In this way, the roof can be roofed by successively tightening the folded roof slats 3 fitted to the tight frame 2.

The folded roof slab 3 attached as described above
This means that the horizontal plate 7 is connected to the rising portion 13 of the lower frame 10.
Is supported by the top plate portion 15 of the upper frame 11 which is received and supported by the top portion 13a of the upper frame 11 so that it can sufficiently oppose a wind load of a positive pressure. By being fitted and locked to the fitting portion 18 and supported, it is possible to obtain high strength against a negative wind pressure,
It can sufficiently counter wind loads in both positive and negative directions. The fitting rib 6 is provided at a position as close to the lower side of the inclined side plate 5 as possible and can be fitted and locked to the protruding fitting portion 18 even in the case of a large negative pressure load. preferable.

The folded roof plate 3 is provided with a fitting rib 6 having a V-shaped cross section on the inclined side plate 5, so that the resistance to bending deformation is also increased. Further, the shape of the fitting rib 6 portion of the folded roof plate 3 is such that the lower end of the rib slope plate 6b and the end of the valley bottom plate 4 are connected via the lower sloped plate 9; The lower part 9 of the side plate is formed to be bent in a substantially U-shape. According to this, when looking at the deformation process when a negative pressure load is applied, as shown in FIG. 6, the valley bottom plate 4 is curved and deformed so as to bulge outward (in a broken line state), and the rib slope plate 6b is formed.
The angle A formed by the lower side plate 9 and the lower side plate 9 and the angle B formed by the lower side plate 9 and the valley bottom plate 4 respectively increase, but the angle C formed by the rib upper surface plate 6a and the rib inclined plate 6b decreases, and Since the dimension X up to the fitting rib 6 does not change, bending deformation such that the rib upper surface plate 6a of the fitting rib 6 rotates around the connecting portion with the lower end of the inclined side plate 5 can be suppressed. The deformation of the plate 4 can be prevented from being transmitted to the rib upper surface plate 6a, and the folded roof plate 3 does not easily come off the tight frame 2.

On the other hand, as shown in FIG. 7, for example, the folded roof plate 3 of the comparative example, the rib 6 for fitting has a rib upper surface plate 6a and an end of the valley bottom plate 4 in which the inclined side plate lower portion 9 is straight.
When the negative pressure load is applied, the valley bottom plate 4 is curved, and the angle B formed between the lower portion 9 of the inclined side plate and the valley bottom plate 4 and the upper portion of the rib upper surface plate 6a and the lower portion of the inclined side plate 5 are formed. Since the angle D increases and the dimension X increases, the rib upper surface plate 6a of the fitting rib 6 bends and deforms so as to rotate around the connection with the inclined side plate 5, and the folded roof plate from the tight frame 2 3 may come off. Such a problem is the same even when the side plate 43 is formed with the protruding portion 44 having the same cross-sectional shape as the fitting rib 6 of the comparative example, like the folded plate 42 of the conventional example shown in FIG. In particular, the folded roof slab 4 of the conventional example shown in FIG.
In No. 2, since the protruding portion 44 is formed near the upper end of the side plate 43, such a problem is easily caused. Therefore, the folded roof shingle 3 of the present invention having the cross-sectional shape shown in FIG. 6 is much more preferable than the folded roof shingle of the comparative example shown in FIG. 7 and the folded roof shingle of the conventional example shown in FIG.

When the roof has a slope, the upper frame 11 is connected to the lower frame 10 so as to be able to cope with the slope of the roof.
With respect to the horizontal axis 28. For this purpose, as shown in FIGS.
1 integrally forms between the left and right bottom plate portions 19, 19 a gate-shaped rising portion 25 that covers the outside of the gate-shaped rising portion 13 of the lower frame 10, and forms the bottom plate portion 19 into an arc-shaped cross section. . Holes 26, 2 are formed in the rising portion 25 of the upper frame 11 and the rising portion 13 of the lower frame 10.
7 is provided on the same axis, a horizontal shaft 28 composed of a headed bolt is inserted into the holes 26 and 27, and a nut 29 is screwed into a threaded end of the horizontal shaft 28 to thereby form the upper frame 1
1 is rotatably connected to the lower frame 10 about a horizontal axis 28. In this case, the diameter of the hole 27 of the lower frame 10 is formed larger than the diameter of the horizontal shaft 28 so that the horizontal movement of the upper frame 11 on the lower frame 10 is not hindered.

The upper frame 11 of this embodiment is slightly deformed from the upper frame 11 of the above embodiment,
5 is formed at the top of the rising portion 25, and the upper end plate portion 16 a of the inclined side plate portion 16 forming the protruding fitting portion 18 is formed at the rising portion 25.
And is formed so as to be substantially horizontal with respect to the top plate 15. That is, the protruding fitting portion 18 is
9, an inclined side plate portion 16 extending obliquely upward from an outer end of the bottom plate portion 19, and an upper end of the inclined side plate portion 16 is attached to the top plate portion 1.
It is formed in the shape of a knife comprising an upper end plate portion 16a which is continuously provided inward and lower than 5. The top plate 15 of the rising portion 25 is received and supported by the top 13 a of the rising portion 13 of the lower frame 10. A substantially horizontal upper end plate portion 16a of the inclined side plate portion 16
Of the rising portion 25 (for example, 2
mm). The leading end 16b of the upper end plate 16a, which forms a gap between the upper frame 11 and the rising portion 25, hits the rising portion 25 at the time of a negative pressure load, and
Deformation can be prevented and strengthened. The same can be said for the tight frame 2 shown in FIGS. 11 to 13, 18 and 19.

The tight frame 2 may be formed in a shape as shown in FIGS. 10 to 12 in addition to the above shape. In the tight frame 2 shown in FIG. 10, the lower frame 10 has the same shape as the lower frame 10 shown in FIG. 1, but the upper frame 11 has no bent pieces 17 like the upper frame 11 shown in FIG. A projecting fitting portion 18 is formed at a corner where the portion 16 and the bottom plate portion 19 intersect.

The tight frame 2 shown in FIG. 11 is different from the lower frame 10 shown in FIG. 1 in that the lower frame 10 is formed in a shape having no rising portion 13. The upper frame 11 is different from the upper frame shown in FIG. The shape is substantially the same as the shape of No. 11. The tight frame 2 shown in FIG. 12 is different from the tight frame 2 shown in FIG. 8 only in that it is not connected by the horizontal shaft 28 and that the upper frame 11 is formed without the bent piece 17. Have the same shape. Lower frame 10 like tight frame 2 shown in FIG.
By forming a double structure of the rising portion 13 of the upper frame 11 and the rising portion 25 of the upper frame 11, it is possible to obtain the tight frame 2 which is extremely resistant to a positive pressure load.

In the above embodiment, since the fitting ribs 6 of the folded roof plate 3 are fitted and locked to the projecting fitting portions 18 of the tight frame 2, the tightening pieces 8 of the folded roof plate 3 are subjected to a negative pressure load. The breaking part is not broken and the folded roof plate 3 can be prevented from scattering, so that it can be mounted without using a shackle. Further, the material cost of the shackle can be reduced, and the work of attaching the hangers can be omitted. .

However, the present invention is not limited to this. As shown in FIG. 13, the upper frame 11 of the tight frame 2 is formed into two parts, left and right. 11a rising section 25, 2

(Second Embodiment) FIG. 18 shows a second embodiment of a folded roof shingle.
An example will be described. The folded roof plate 3 of this embodiment has a rib upper surface plate 6 similar to the fitting rib 6 of the folded roof plate 3 of the first embodiment.
a and a rib-shaped inclined plate 6b, a knife-shaped projecting fitting portion 18 of the tight frame 2 shown in FIG. Recessed part 30 fitted together with part 16 and upper end plate part 16a
Is provided. The concave portion 30 has a rib upper surface plate 6 a of the fitting rib 6, and is formed upwardly at substantially the same gradient as the inclined side plate 5 continuously to the rib upper surface plate 6 a and along the inclined side plate portion 16 of the tight frame 2. It is formed of a concave bottom plate 30a and a concave top plate 30b which is formed substantially horizontally outward on the upper end of the concave bottom plate 30a and is formed along the upper end plate portion 16a of the tight frame 2.

The folded roof slab 3 formed in such a shape
Since the rib 6 for fitting is formed in a cross-sectional shape in which the rib slope portion 6b and the lower portion 9 of the inclined side plate are formed in a substantially U-shape as in the case of the folded roof plate 3 of the first embodiment, Even when a large negative pressure load is applied to the plate roof plate 3 and the valley bottom plate 4 swells outward and deforms, the deformation of the rib upper surface plate 6a can be suppressed as much as possible. Detachment from the protruding fitting portion 18 can be effectively prevented. According to the cross-sectional shape of the folded roof plate 3, in addition to the bent portion where the rib upper surface plate 6a and the concave bottom plate 30a intersect, a bent portion where the concave bottom plate 30a and the concave upper plate 30b intersect, The number of bent portions where the concave upper surface plate 30b and the inclined side plate 5 intersect increases, and the strength of the roof plate can be increased by the amount of the bent portions, so that the roof plate is less likely to be deformed by a negative pressure load or a positive pressure load. The joint rib 6 can be more effectively prevented from coming off the protruding fitting portion 18. Further, the folded roof plate 3 is provided with the concave bottom plate 3
Since two bent portions, namely, a bent portion where the upper surface plate 30b intersects with the concave upper surface plate 30b and a bent portion where the concave upper surface plate 30b and the inclined side plate 5 intersect, also engage with the protruding fitting portion 18. The engagement and locking force of the plate roof plate 3 with respect to the protruding engagement portion 18 can be increased, and in this respect, the negative pressure load can be sufficiently counteracted. When a positive pressure load is applied, the horizontal plate 7 is received by the top plate 15, the concave bottom plate 30a is received by the inclined side plate 16, and the concave top plate 30b is received and supported by the upper end plate 16a. And can withstand a positive pressure load sufficiently. In addition to the knife-shaped protruding fitting portion 18 of the tight frame 2 shown in FIG. 12, the knife-shaped protruding fitting portion 18 shown in FIGS. it can.

(Third Embodiment) FIG. 19 shows a third embodiment of a folded roof shingle.
In the folded roof plate 3 of this embodiment, which is an embodiment, a rib upper surface plate 6a and a protruding end of the rib upper surface plate 6a and an end of the valley bottom plate 4 are provided at a position near the lower end of the inclined side plate 5. Lower 9
To form a fitting rib 6 which is connected by a square. And
On the upper part of the fitting rib 6, the folded roof plate 3 of the second embodiment is provided.
8, 11, 12, 13, etc., is provided with a concave portion 30 in which the projecting fitting portion 18 of the tight frame 2 is fitted together with the inclined side plate portion 16 and the upper end plate portion 16 a. is there.

That is, the folded roof slab 3 of the third embodiment.
Also in the concave portion 30 of the second embodiment, the rib upper surface plate 6a of the fitting rib 6 is similar to the concave portion 30 of the folded roof plate 3 of the second embodiment.
And a concave bottom plate 30a formed upwardly and continuously to the rib upper surface plate 6a and along the inclined side plate portion 16 of the tight frame 2, and a substantially horizontal outwardly continuous upper end of the concave bottom plate 30a. And a concave upper surface plate 30b along the upper end plate portion 16a of the tight frame 2. Therefore, the folded roof plate 3 also has a cross-sectional shape having a bent portion where the concave bottom plate 30a and the concave top plate 30b intersect and a bent portion where the concave top plate 30b and the inclined side plate 5 intersect. The strength of the shingle can be increased by the amount of the bent portion, and the roof plate is hardly deformed by a negative pressure load or a positive pressure load. The folded roof plate 3 also has two bent portions, that is, a bent portion where the concave bottom plate 30a and the concave top plate 30b intersect, and a bent portion where the concave top plate 30b and the inclined side plate 5 intersect. Because it will engage with 18,
The fitting and locking force of the folded roof plate 3 with respect to the protruding fitting portion 18 can be increased, and it is possible to sufficiently counteract a negative pressure load or a positive pressure load.

As in each of the above-described embodiments, the tight frame 2 has a form in which the upper frame 11 is connected to the upper side of the lower frame 10 fixed to the base material 1 so as to be movable in the left-right horizontal direction. It is preferable that the fitting rib 6 can be smoothly and easily and surely fitted and locked to the projecting fitting portion 18 of the tight frame 2 without damaging or deforming the plate roof plate 3. It is not limited to the tight frame 2 in which the frame 10 and the upper frame 11 are configured separately. The present invention is, for example, shown in FIG.
0, as shown in FIG. 21, the same applies to a general form in which the entire tight frame 2 is integrally formed. However, the tight frame 2 needs to be formed to have at least the top plate portion 15 for receiving the horizontal plate portion 7 of the folded roof plate 3 and the projecting fitting portion 18.

[0043]

According to the folded roof slab of the present invention, even when a positive pressure load, a negative pressure load, or a particularly large negative pressure load is received, the projecting fitting portion of the tight frame does not come off from the projecting fitting portion. Therefore, the effect of preventing scattering due to a large negative pressure load can be further enhanced.
