Description

[Detailed Description of the Invention] The present invention relates to a crimp structure for folded roofing materials, which is applied when joining the roofs of buildings such as factories and lecture halls.

This type of folded roofing material has valleys on both sides of the peaks.
The peaks and troughs are alternately formed by connecting the inner sloping surfaces facing each other in a V-shape, and at the ends of the troughs, outer sloping surfaces that rise outward and upward are formed respectively. Moreover, a seam portion is formed at the tip edge of the outer inclined surface, and a bulging seam portion is formed at the mountain portion.

By the way, when fixing a plurality of such folded roofing materials to a receiving frame, the following consideration must be taken.

If the seams of adjacent folded roofing materials and the bulging seams at the peaks are not strongly connected together with the hangers, the installation strength will be very low, and the folded roofing materials will be easily damaged by wind pressure, etc. It gets rattled. In addition, in the case of wind pressure equal to that of a typhoon with a wind speed of several tens of meters or more, the upwelling phenomenon is severe and the hanger comes off from the seam, creating a very dangerous situation. In particular, the above-mentioned disadvantages become more pronounced as the length of the folded roofing material becomes longer or the folded roofing material becomes wider and has more ridges. Therefore, it is necessary to firmly connect the seam joints and the bulging seam parts together with the hanger.

Unless the same seam tightening roller can be used to tighten the seams between seams and to tighten the bulging seams, work efficiency will be significantly reduced. Also,
Unless the hangers are all the same so that they can all be tightened, errors are likely to occur and work efficiency will be reduced. Furthermore, there is a risk that the desired sealing strength may not be obtained due to incorrect attachment of the hanger. Therefore, it is necessary to be able to tighten seams between seam joints and tighten seams at bulging seam parts using the same hanger and the same seam tightening roller.

If the appearance shape of the seam joint after seam tightening and the appearance shape of the bulging seam seam are inconsistent,
It is necessary to make all of these external shapes the same, as it would be very unsightly.

The work of inserting the hanger in the bulging seam part is easy.

After tightening the above-mentioned bulging seams,
Do not create a shape that allows water droplets to collect on the shoulder surface between the hem of the bulging seam and the inner slope of the trough.

The present invention has been made with attention to the above circumstances, and is intended to satisfy the above matters.

Hereinafter, the present invention will be described with reference to embodiments shown in the drawings.

The present invention forms the ridges 7 and troughs 6 alternately by connecting the troughs 6 on both sides of the ridges 7 with inner inclined surfaces 8 facing each other in a V-shape, and also forms the ridges 7 and troughs 6 alternately. A bulging seam part 9 is formed at 7, and the space between the hem parts 9c on both sides of the bulging seam part 9 is such that the hanger 14 can be inserted without any trouble, and the hem part Upwardly inclined shoulder surfaces 17, 17 are formed between 9c, 9c and the upper ends of the inner inclined surfaces 8, 8, and these shoulder surfaces 17, 1
7 is formed so that the hem portions 9c, 9c sides slope upward after the bulging seam tightening portion 9 is tightened, and at the ends of the valley portions 6, there are respectively raised outward and upward directions. In addition, an internal seam 5 is formed at the tip edge of the outer inclined surface 3 on one side, and an inner seam 5 is formed at the tip edge of the outer inclined surface 2 on the other side. A plurality of folded roofing materials 1, 1', 1'', etc. formed to form the outer seam 4 are laid out on the receiving frame 12, and the receiving frame 12 is provided with the inner and outer seams 4. 5, 4 and the bulging seam fastening part 9 are provided with hangers 14 of the same shape. 5 on the outer surface of the hanger 14 and tighten the seam over the entire length, and tighten the hanger 14 at a position corresponding to the bulge seam with a bulge. By overlapping the inner surface of the section 9 and tightening the bulging seam portion 9 over its entire length, the inner and outer seam joints 5, 4 and the bulging seam portion 9 are made to have approximately the same shape. It is formed by

On the receiving frame 12 configured in this way,
The folded roofing material 1, 1' of the present invention shown in FIG.
1"... are arranged side by side as shown in Fig. 2. Also, the outer seam formed at the tip edge of the outer inclined surface 3 on one side of the folded roofing materials 1, 1', 1"... 5 on the inner surface of the head 14a of the corresponding hanger 14, and an outer seam formed at the tip edge of the outer inclined surface 2 on the other side of the adjacent folded roofing material 1, 1', 1''... The hooks of the hanger 14 are overlapped on the outer surface of the head 14a of the hanger 14, and the hooks of the hanger 14 are placed on the inner surface of the bulging seam portions 9 formed on the peaks 7 of the folded roofing materials 1, 1', 1''... The shaped heads 14a are stacked and placed on the receiving frame 12. Then, using one seam tightening roller (not shown), the outer seam joint 4 and the inner seam joint 5 are seamed from the state shown in FIG. Then, from the state shown in FIG. 4, as shown in the figure, the bulging seam tightening portion 9 is tightened over its entire length in the longitudinal direction with the aforementioned seam tightening roller, thereby forming the inner and outer seam joints 5. , 4 and the bulging seam portion 9 are formed in substantially the same shape, and are assembled to the receiving frame 12 for the folded roofing materials 1, 1', 1''... In other words, the folded roofing materials 1, 1', 1''... The seams 4 and 5 of 1 are connected to other folded roofing materials 1' and 5 adjacent to each other.
1'', one of the outer seam joints 4 is locked to the outer surface of the hook-shaped head 14a of the hanger 14, and the inner side of the other folded roofing material 1' adjacent to this is The seam joint part 5 is engaged with the inner surface of the hook-shaped head 14a of the suspender 14, and the other inner flap joint part 5 is engaged with the inner surface of the hook-shaped head 14a of the suspender 14, and the adjacent The outer seam 4 of the other folded roofing material 1″ has a hanger 14
It is secured to the outer surface of the hook-shaped head 14a of the
The folded roofing material 1 and the other folded roofing materials 1', 1'' adjacent thereto are joined by seaming the respective seam portions 4, 5.

By the way, the peaks 7 of the folded roofing materials 1, 1', 1''...
A bulging seam part 9 whose front face is bulged out in a mushroom shape is formed at the center position, and the area between both side hems 9c and 9c of this bulge seam part 9 is as shown in FIGS. 1 and 2. As shown in FIG. 4, etc., the spacing is such that the head 14a of the hanger 14 can pass through it without any trouble.

In other words, by forming the width between the hem portions 9c, 9c to be approximately the same width as the width of the head 14a of the hanger 14, the bulging seam portion 9 can be adjusted to the hook-shaped head 14a of the hanger 14. If it is located in the upper position, the hem portion 9 will be moved by the weight of the folded roofing material and the elasticity of the bulging seam portion 9.
c, 9c expands slightly to reveal the hook-shaped head 1 of the hanger 14.
4a is inserted into the top surface 9a of the bulging seam 9, and therefore can be inserted without any trouble without using any insertion tool.

Then, the sturdy hanger 14 is inserted into the bulging seam part 9c from between the both side hem parts 9c, 9c, and the bulging seam part 9 and the receiving frame 12 are connected after the seam is tightened. It is possible to configure the installation strength to be strong.

Further, between the both side hem portions 9c, 9c and the upper end portions of the inner inclined surfaces 8, 8, there are shoulder portions 1, respectively.
7 and 17 are formed.

This shoulder surface portion 17 has a curved surface 10 corresponding to the shape of the top surface 9a of the bulging seam portion 9 connected to the hem portion 9c, and an inclined surface 10a connected to the upper end portion of the inner inclined surface 8. The shoulder surface portion 17 as a whole is formed such that the hem portion 9c side is inclined upward. Further, as shown in FIG. 4, the shoulder surface portions 17 are formed so that the hem portions 9c, 9c side face upward even after the bulging seam portion 9 is sewn. In other words, the inclined surface 10a
is formed so that the horizontal or hem portion 9c side faces slightly upward, and furthermore, the curved surface 10 is formed so as to face upward. With this structure, even if the base of the bulging seam part 9, that is, the shoulder surface part 17 is deformed downward when the bulging seam part 9 is sewn, the shoulder surface part 17 or its vicinity will not be affected. There is no formation of recesses where rainwater accumulates or where dust accumulates, thereby effectively preventing corrosion of the folded roofing material.

Further, in the valley portions 6, 6 of the folded roofing materials 1, 1', 1''..., both side edges 6 of the valley bottom surfaces 6a, 6a
b... are upright with respect to the valley bottom surfaces 6a, 6a, respectively, to form upright surfaces 18..., and these upright surfaces 18... are continuously formed below the respective inclined surfaces 2, 3, 8... There is. The rising height of the upright surfaces 18 is set to a dimension that increases the section modulus of the bottom surfaces 6a, 6a of the troughs 6, 6, and provides sufficient strength.

The folded roofing material of the present invention constructed as described above has the following effects.

A folded roofing material in which an internal seam 5 is formed at the leading edge of the outer inclined surface 3 on one side, and an outer seam 4 is formed at the leading edge of the outer inclined surface 2 on the other side. 1, 1', 1''... are laid out on the receiving frame 12, while the receiving frame 12
Hangers 1 of the same shape are placed at positions corresponding to the inner and outer seam joints 5 and 4 and the bulging seam tightening part 9.
4, the inner seam 5 overlaps the inner surface of the hanger 14 at the corresponding position, the outer seam 4 overlaps the outer surface of the hanger 14, and the seam extends over the entire length. In addition, a hanger 14 of the same shape as that used for the above-mentioned seam portion, located at a position corresponding to the bulging seam portion 9, is attached to the inner surface of the bulging seam portion 9. Since the bulging seam portions 9 are overlapped and seamed over the entire length, the rate of seam tightening of the inner and outer seam joints 5 and 4 and the ratio of the bulging seam portions 9 are Both the rate of seam tightening and the state of tightening are plastically deformed, and by using the same seam tightening roller and tightening these in sequence, work efficiency can be greatly improved. .

On the outside side of each hanger 14, there are only outer seam joints 4, bulging seam fastening parts 9, which correspond to the thickness of one roof board, and the same seam fastenings are applied to these parts. Since all you have to do is tighten the seams with a roller, the seam tightening work can be done very smoothly and reliably.

The inner and outer seam joints 5, 4 and the bulging seam tightening portion 9 that have been seamed are tightened by the same seam tightening roller so that the external shape is approximately the same. Because each folded roofing material 1,
The tops of the mountains 1', 1'', etc. have a uniform appearance, making it possible to obtain a good-looking roof.

Inner and outer seam joints 5 and 4 of adjacent folded roofing materials
Since the bulging seam tightening portion 9 of the folded roofing material is tightened over its entire length via the hangers 14, it not only looks good but also improves the appearance of the folded roofing material. Sufficient mounting strength is ensured at both ends, the middle, and other parts, and there is no risk of rattling noise even under wind pressure of tens of meters or more.

A bulging seam part 9 is formed on the mountain part 7 of the folded roofing material 1, and both side hem parts 9 of this bulging seam part 9 are formed.
Since the spacing between c and 9c is large enough to allow the suspender 14 to be inserted, the sturdy suspender 14 can be easily inserted into the bulging seam part 9, and the bulging seam can be easily inserted. The work of inserting the hanger 14 into the tightening part 9 can be done very easily, and the sturdy hanger 14 allows the bulging seam tightening part 9 to be inserted easily.
It is possible to securely perform the sash tightening construction.

Moreover, even if the width between the hem portions 9c and 9c on both sides is formed at such an interval that a hanger can be inserted in order to perform the seam fastening construction firmly,
Upwardly inclined shoulder surfaces 17, 17 are formed between the both side hem portions 9c, 9c and the upper ends of the inner inclined surfaces 8, 8, and these shoulder surfaces 17, 17 are connected to the edges of the bulging seam portions 9. Even after tightening, the hem portion 9c side is formed so as to face upward, so that the shoulder surface portion 1
7 and 17 can maintain an upwardly inclined state even after the bulging seam fastening portion 9 is fastened. For this reason, when the bulging seam is tightened, the shoulder surface slopes downward, and as a result, a recess is formed, for example, at the connection site between the shoulder surface and the hem, and rainwater, dust, etc. Compared to those that accumulate corrosion etc. of folded roofing materials, the folded roofing materials of the present invention can effectively prevent corrosion of folded roofing materials because such concave portions are not formed. effective.

Incidentally, as in the above embodiment, the upwardly inclined shoulder surfaces 17, 17 have a curved surface 1 corresponding to the shape of the top surface 9a of the bulging seam fastening portion 9 on the side of the hem portions 9c, 9c.
0, 10, when the folded roofing materials 1, 1', 1'', etc. are stacked upward and downward as shown in Fig. 5, the bulge of the lower peak 7 will be reduced. The crimp portion 9 is in contact with the inner surfaces of the curved surfaces 10, 10 of the upper shoulder portions 17, 17, and is held in a stable state between the shoulder portions 17, 17, so that the stacked folded roofing materials 1, 1', 1"... is unlikely to occur, resulting in instability of the folded roofing materials 1, 1', 1"... and inconvenience in transportation work and loading onto beams. ,
This has the advantage of effectively preventing deformation of the folded roofing materials due to local loads due to mutual positional displacement between the folded roofing materials.

In addition, the folded roofing materials 1, 1', 1'', etc. of the present invention are as follows:
The embodiment is not limited to the above embodiment, but may be formed with three valleys 6 and two peaks 7, 7, as shown in FIG.
Hanging surfaces 17a, 17 are attached to the edges of the shoulder surfaces 17, 17.
a... is formed continuously on the upper part of each inclined surface 8..., or hanging surfaces 17a', 17a' are formed on the edges of the shoulder surface parts 17', 17' at the upper part of both outer inclined surfaces 2, 3. You may. Such hanging surfaces 17a...,1
By forming 7a' and 17a', the strength against positive pressure can be further strengthened. In addition, in FIG. 6, parts corresponding to the embodiments described above are given the same reference numerals.
