Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a synthetic resin-made folded roofing material and a synthetic resin-made folded roofing material.
Alternatively, the present invention relates to a connection structure between a synthetic resin-made folded roof material and a metal-made folded roof material.

[0002]

2. Description of the Related Art Heretofore, when a skylight for lighting is provided on a folded roof, a transparent or translucent polycarbonate folded roof material having a lighting property has been attached to the skylight portion. . In this case, in the folded roof material in which the ridges formed at the side end portions of the valleys can be superposed in close contact with each other, the top wall surfaces of the superposed portions are integrally connected by bolts, In such a connection structure, not only there is a possibility that rainwater may enter from the bolt hole, but also there is a problem that the bolt is corroded and cannot be used for a long time.

For this reason, as shown in FIG. 7, the ridges 4 having a constant width are bent laterally outward at both end edges of the valleys 41.
2 and 43, and a vertical leg piece 44 bent upward at the protruding end of one of the peaks 42, and this vertical leg piece 44
A bent edge 45 having a U-shaped or C-shaped cross section with a downward opening 46 is formed at the upper end of 44, and a vertical rising edge 47 having a constant height and bent upward at the horizontal protruding end of the other mountain portion 43. Has been developed.

In order to connect the folded roof members 40, 40, as shown in FIG.
After covering the bent edge 45 of one folded roofing material 40 on 32, the bent edge 45 is subjected to flattening so as to be in surface contact with the outer peripheral surface of the hook 31, and the other flattened folding is performed. After enclosing the rising edge 47 of the plate roofing material 40 in the upper bent portion 32 of the hanging member 31, cover the metal cap 51 with a C-shaped cross section with a downward opening, and use a manual folding device or a self-propelled folding device. The metal cap 51
Are connected by pressing.

[0005]

However, when pressed by a manual folding device or a self-propelled folding device,
Since the bent edge 45 of the polycarbonate-made folded roof material is the tip of the suspension and is bent inward in the cold state with the contact portion as a fulcrum, a large internal stress due to a concentrated load is applied to the bent portion. Occurs, the internal stress remains as strain, and there is a possibility that cracks may occur due to long-term use.

Also, a polycarbonate-made folded plate roofing material
As described above, the bent edge portion 45 of 40 is subjected to processing so as to completely contact the outer peripheral surface of the suspender in order to securely fix the suspension to the suspender. In addition to the labor required, the bent edge 45 deformed by the cutting process tends to return to its original shape due to its restoring force. When a positive or negative pressure such as pressure or wind pressure acts, the fixing force of the bent edge 45 is loosened, and there is a possibility that the bent edge 45 may be detached from the hook.

To prevent this, as described above,
The bent edge portion 45 is provided with a metal cap 51 having a C-shaped cross section having a downward opening.
After the cap 51 is covered with the metal cap 51, the deformed shape of the bent edge 45 is fixed by the holding force of the metal cap 51. It is difficult to cover the inner peripheral surface of the metal cap 51 with a uniform pressing force over the entire outer peripheral surface of the metal cap 51. There is a risk that rainwater will enter through this gap due to capillary action. If the metal cap 51 is pressed too tightly to eliminate this, excessive force is applied to the bent edge 45 of the polycarbonate-made folded roof material 40, which increases internal distortion and causes cracks. Therefore, it could not be tightened too strongly.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to easily and accurately connect to each other without causing intensive residual stress inside. Another object of the present invention is to provide a folded roofing material made of synthetic resin, which is rich in watertightness, has a simple structure and is easy to manufacture, and a connection structure therefor.

The metal caps 13 are used to connect the adjacent folded folded roofing materials A, A to each other via the hooks 9 without using bolts.

The metal cap 13 is formed so that the shape of the half portion 13a before being pressed does not come into contact with the outer peripheral surface of the large refraction piece 8 of the folded folded roofing material A, and the outer peripheral surface thereof does not touch the outer peripheral surface. It is gently curved so as to form a gap, and is pressed so that one half 13a is inscribed in the bending pieces 8a to 8d of the large bending piece 8 of the roof material A. In any case, the large-sized refraction piece 8 of the folded-type roofing material A is in contact with the outer peripheral surface of the bent portion 12b of the hanging member 12, so that the metal cap 13 is pressed. There is no danger of deformation at the time, and no stress is applied to the large refraction piece 8, and therefore, no residual strain remains.

Further, the other end portion 13b of the metal cap 13 curved in an arc shape allows the tip surface of the suspension 12 to be
When covering the front end surfaces of the large and small refraction pieces 8 and 9 of the folded roof materials A and A superposed on both side surfaces of the metal cap 13 and the other half 13b of the metal cap 13, A band-shaped packing 14 having a fixed width is interposed therebetween, and the metal cap 13 is pressed against the inner peripheral surface of the other half portion 13b of the metal cap 13 and the tip of the large refraction piece 8 to form a small refraction piece. 9 constitutes a watertight structure with a packing 14 interposed over the lower surface.

As described above, in the connection structure of the adjacent synthetic resin-made folded roof materials A, A, the lower end portions (the valley portion 1 and the inclined plate portion 2, 3) may be blown up by wind pressure. In order to prevent this, as shown in FIG. 5, a U-shaped cross section substantially equal to the cross-sectional shape of the folded roof material A as shown in FIG.

As described above, according to the folded roofing material made of synthetic resin of the present invention, the large refraction piece formed on the upper end of the standing piece at the edge of one of the hills is processed. Since it is formed in a polygonal refraction piece that opens outward so as to circumscribe the outer surface of the suspension without applying it, the structure is simple and easy to manufacture. The large refraction piece extends straighter than the part and is easy to handle, and can be easily covered on the upper bent part of the suspension without any processing, and each refraction piece bent into a polygonal shape is suspended. The outer window is circumscribed in a line contact state with good familiarity over the entire length of the child, so that accurate skylight construction can be performed. Furthermore, since the small refracting piece formed at the upper end of the upstanding piece at the other mountain portion of the synthetic resin-made folded plate is formed in a cross-sectional shape that can be included in the upper end of the hook, it is large. Like the refraction pieces, they can be easily and accurately arranged inside the suspension, and the skylight can be installed efficiently. In addition, these large and small refraction pieces can reduce the localized concentrated load. Therefore, there is no possibility that a large residual strain is generated inside, and therefore, it can be used for a long time.

Further, according to the connection structure of synthetic resin folded roof materials according to claim 2 of the present invention, the small refraction piece of one of the folded folded roof materials is attached to the upper end bent portion of the hook. A large refraction piece of the other foldable roofing material is covered on the inside of the hanger without performing a knurling process, and each of the refraction pieces bent into a polygonal shape is circumscribed on the outer peripheral surface of the hangover. Further, one half of the metal cap having a downward opening is placed on the large refraction piece, and the inner peripheral surface of the metal cap is inscribed with the corner of each refraction piece of the large refraction piece. The other half of the metal cap is clamped in the direction that encloses the tip of the large and small refraction piece and the hook without deforming the tip of the large refraction piece, so that the metal cap has an arc shape. The corners of each refraction piece of the large refraction piece whose inner peripheral surface of one half curved to a polygonal shape is fully bent Inscribed in line contact state over,
A connection structure with excellent watertightness that can surely prevent rainwater from penetrating can be configured.

Further, the other half of the metal cap covered with the large refraction piece is pressed in a direction to include the tip of the large and small refraction piece and the hook without deforming the tip of the large refraction piece. Therefore, by tightening only the metal cap, it becomes possible to connect the folded roof materials, and requires a manual clamping device or a self-propelled folding device that requires an unnecessarily large clamping force. The connection can be made simply, efficiently, and securely without the need to perform a concentrated load on the large and small refraction pieces when the metal cap is clamped.
There is no fear that large residual strain is generated in these large and small refraction pieces, and a folded folded roof structure that can withstand long-term use can be formed.

Further, as described in claim 3, in the connection structure between the small refraction piece in the metal-made folding roof material and the large refraction piece in the synthetic resin-made folding roof material, Similarly, it is possible to provide a folded folded roof material structure which can be easily and accurately performed using a metal cap and can be used for a long time.

According to the fourth aspect of the present invention, a packing is provided between the other half of the metal cap having the downward opening, the large and small refracting pieces covered by the other half, and the tip of the hook. Since it is interposed, it is possible to obtain not only a connection structure in which rainwater infiltration is reliably prevented by the packing, but also uniform contact between the metal cap and the large and small refraction pieces and the end of the suspension through the packing. A surface contact structure can be obtained, and a high-precision folded plate roof structure having high precision and excellent strength can be obtained.
