Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to improvements in double-folded plate materials used primarily for roofs. [Juukan Technique 1 Jubei, as a folding plate material as mentioned above, for example, JP-A-61-
As shown in No. 254737, a heat insulating material is filled between ff1 parts in the width direction of the outer metal plate in a cross-sectional shape in which peaks and valleys are alternately continued by sloped parts. ，
Both sides of the outer metal plates are brought into contact with each other, one side edge of the inner and outer metal plates is lengthened and folded back, and the edge of the other side of the inner and outer metal plates is clamped at the folded part. there were. [Problems to be Solved by the Invention] Since the conventional double folding plate material with inner and outer metal plates has the above-described structure, it is difficult to form an air layer or an air passage between the inner and outer metal plates. In addition, the connection pattern in the width direction is complicated, such as lengthening one side edge of the inner and outer metal plates to form a folded part, making it troublesome to manufacture. There was a 7% disadvantage that it was difficult to connect to. The present invention was made to solve the above-mentioned problems, and it is possible to form an air layer or an air passage between the inner and outer metals, and also to easily connect them in the arm direction and width direction. ,
Moreover, the object is to provide a double-folding plate material that is easy to manufacture and inexpensive.

[1,000 Steps to Solve the Problems] The double folding plate material of the present invention has a cross-sectional shape in which peaks and valleys are alternately continued by sloped parts, and these metal plates are placed between the inner and outer metal plates. A space is formed over the entire surface, and at least one of the peaks and valleys in this space is provided with a spacing member for regulating the distance between the inner and outer metal plates, and a folding plate is provided along the peaks and valleys. A connecting part consisting only of an outer metal plate having a peak part of at least 1l1 and an inclined part continuing to the outside thereof was extended on one side edge of the material.

[Function] Since the double folding plate material of the present invention has a dark space at the opening of the inner and outer metal plates that covers almost the entire surface of these metal plates, this space can function as an air layer or an air passage. At the same time, since the inner and outer metal plates are separated by the space at both ends in the longitudinal direction, the lower ends of the inner and outer metal plates of the double folding plate located above can be connected to the other two ends located below. By stacking and supporting the upper ends of the inner and outer metal plates of the double-folded plates, these double-folded plates can be easily connected in the direction of force (usually in the direction of the eaves). Moreover, it does not cause any problems such as rain leaks. On the other hand, since the inner and outer metal plates are arranged with a dark space maintaining member interposed between the peaks and valleys of the space, or one of these, adhesives, spot welding, etc. may be required depending on the material and shape of the space maintaining member. The spacing member and the inner and outer metal plates can be fixed using an appropriate fixing means, and this makes it easy to mold the inner and outer metal plates, and the thickness of the space is uniform in each part. can be manufactured easily and inexpensively. Further, the double folding plate material of the present invention is made only of an outer metal plate having at least 111 peaks and an inclined part continuing to the outside thereof on one side edge of the folding plate material along the peaks and valleys. Since it has a structure in which the connecting part is extended, when connecting the folding plate materials laterally (in the direction of the main building perpendicular to the above-mentioned hanging direction), the connecting part consisting only of the outer metal plate should be connected to the side. It is possible to easily polymerize from above the peaks or slopes located at the side edges of other double-folded plates without interfering with each other. In this case, the connecting part becomes aS that covers the side edge of the other adjacent double folded plate material by the mountain part and the slope part continuous with the mountain part, so there is no possibility that water etc. may enter from the connecting part. do not have. Also, the inner and outer metal JKI between adjacent double folding plates! Since the space in between can be formed continuously, it is possible to sufficiently maintain the heat insulation properties and strength characteristic of double prayer plate materials even in the joint parts. [Examples] Examples of the present invention will be described below based on the drawings.

(2) They may be arranged at a plurality of locations in the direction of the hand force at appropriate intervals. However, it is preferable not to provide it at one end or both ends in the direction of force. On the other hand, as shown in FIG. 2 or 3, this double-folding plate material has an inner connecting portion (1e) with only the inner metal (1) disposed on the side at one side edge. However, on the other side edge, an outer connecting portion (2e) is provided in which only the outer metal R plate (2) is applied to the side force. The outer connecting portion (2e) has a peak portion (1) located at the end of the inner metal plate (1).

It ends with (ld). Note that this structure actually consists of inner and outer metal plates (1). As (2), the same number of peaks (la), (2a) and valleys ITh(To),
(2b), and overlap each other by shifting one peak part in the width direction. This can be easily manufactured. A large number of the double-folded plates of the above-mentioned embodiment are formed in a row in the eave direction and in the left-right direction to form the roof or outer wall of a building as described below. In other words, the connection in the direction of the eave ridge is to connect the eave side i part of the inner and outer * metal plates (1) and (2) of the double folding plate material located on the ridge side to the Inner and outer metal plates of folding plate material (1).
(2) are layered and supported on the ridge side bolts, making it more difficult for rainwater to enter the inside of the building than the outer metal plate (2), and even if a small amount of rainwater does enter the inner metal plate ( 1) Since the water flows over the eaves and is sequentially guided from the edge of the eaves onto the inner metal plate (1) of the other double-folded plate material connected to the eaves, it is discharged to the outside, so there is no risk of leakage. In addition, the space 3) between the inner and outer metal plates (1) and (2) not only provides heat insulation and soundproofing functions, but can also be used as an air passage for ventilation by opening the top! For example, it is possible to prevent warm air in the summer from stagnating in the space (3). Furthermore, when the double folded plate material of this example is used for a roof in a snowy area, by making the spacing member (4) strong, it is possible to connect these and the inner and outer metal plates (1).
．． (2) peaks (la), (2g) and valleys 1'ffi
(lb). By forming a box-shaped closed cross-section portion with the barbed edges (2b), a high-strength roof capable of withstanding the weight of snow can be obtained.

On the other hand, when connecting the double folding plate materials in the width direction, as shown in FIG. A mountain part (2a) of the outer metal plate (2) located at the base is of the inner connecting part (1e) so as to partially overlap with the inner connecting part (1e) of another adjacent double new plate material. Polymerize with At the same time, the peak (1a) of the inner metal plate (1) of the other folding plate material is superposed on the peak (1a) of the inner connection 1fft (le). In the dark space (3) of the inner and outer connecting parts (le) and (2e), there are peaks (3a) and valleys (3b).
A spacing member (4) is interposed between the spacing member (4) and the metal plate (IL (2), and the adjacent outer metal plates (2), (2) are interposed as necessary. Connection in the width direction is completed by fixing with fixing means such as welding or screws.

In this way, it is extremely easy to connect the double folding plate materials in the width direction, and according to this connection structure, the connecting part (2e) is formed by the mountain part (2a) and the slope part (2c) continuous thereto. Since the side edges of other adjacent double folding plates are covered, rainwater that has fallen on the connecting part (2e) will not flow around into the inner space (3) of the folding plates, and it will be possible to Demonstrates waterproof properties. In addition, since the inner and outer metal plates (+) and (2) open spaces can be continuously formed between adjacent double-folded plates, the insulation and strength characteristic of double-folded plates are combined. It is possible to sufficiently hold even the parts.

It should be noted that the double-folded plate material of this example can be manufactured to the desired dimensions by on-site processing by using a roll 7 smoothing process, etc., but instead of doing this , those that have been finished to predetermined dimensions in the hand force direction and V#A direction at the factory stage (generally called "standard length materials")
That's what it means. ) is preferable, and by making it into a fixed-length folded version, handling, transportation, and construction are easier.
It also improves economic efficiency because there is no wastage of materials. In addition, in the double-folded plate material of this example, the outer connecting portion is formed by overlapping the inner and outer metal plates having the same number of peaks and valleys with one peak in the width direction. (2e) and the inner connecting portion (le), and in this case, the rectangular corrugated plate for the double folding plate from Junmai can be used almost as is, so the manufacturing cost can be significantly reduced. I can do it. On the other hand, as shown in FIG. 2 or 3, the dark spaces (
3c) may be filled with a heat-insulating and sound-absorbing material (5) made of glass wool, foamed material, etc., thereby making it possible to further improve the heat-insulating and sound-absorbing performance of the double-folded plate material. FIG. 5 shows a second embodiment of the present invention. In this embodiment, a plurality of pipe materials (6) are brought into close contact with each other in the left-right direction to constitute a spacing maintaining member (4). ) The same heat-insulating and sound-absorbing material as in the second embodiment (5
). Note that the configuration of this embodiment other than those described above is the same as that of the first embodiment.

FIG. 6 shows the #IJ3 embodiment of the present invention. In this embodiment, a spacing member (4) having an arcuate cross section is fixedly provided on the inner metal plate (1) within the peaks (3a) and troughs (3b) of the space (3), and Space (3) other than inside the holding member (4)
) is filled with insulation material made of foam material (5), including the spacer member (4) above MS. Note that the configuration of this embodiment other than those described above is the same as that of the first embodiment. FIG. 7 shows a PIS5 embodiment of the present invention. In this embodiment, inner and outer metal plates (1). (2) has a wavy cross section with continuous convex arc portions and concave arc portions, and the inner and outer metal plates (1),
(2) Valley part (3b
》A spacing member similar to that of the first embodiment (
4), and heat insulation, ryj. Sound materials (5)
This is a formalization of the following. #The configuration other than those described above is the same as that of the first embodiment.

In addition, in each of the above embodiments, the inner and outer metal plates (
1). (2) with the same number of mountains fi(la), (2a
) and valleys (11+), (2b),
The structure is such that these are overlapped by shifting them one direction, but instead of doing this, only the outer connecting part (2e) made of the outer metal plate (2) is provided, and this is connected to the other adjacent double fold. It is also possible to have a structure in which the polymerization is carried out on the side edges of the plate material over a range where they do not interfere with each other, that is, over the length of the connection n (2e). , it is possible to maintain the characteristic of low cost. In addition, in each embodiment, the spacing maintaining member (4) was provided in the peak portion (3a) and the valley portion (3b) of the space portion (3), but the location of the spacing maintaining member (4) was folded. This depends on the required strength of the plate material, and therefore, when the required strength is low, the spacing member (4) may be provided only at the crests (3a) or troughs (3b) of the space [Advantage 1 of the invention] As explained above, according to the double folding plate material of the present invention, a space is formed in the darkness of the inner and outer metal plates, covering almost the entire surface of these metal plates. In addition, since the inner and outer metal plates are separated by the space at both ends in the direction of force, the lower ends of the inner and outer metal plates of the double folding plate material located above are separated. By stacking and supporting the upper ends of the inner and outer metal plates of other double folding plate materials located below, these double folding plates can be easily connected in the direction of force. Moreover, it does not cause problems such as rain leaks. On the other hand, since the spacing member is interposed between the inner and outer metal plates at the peaks and valleys of the space, or one of these, the material of the spacing member,
The spacing member and the inner and outer metal plates can be fixed using an appropriate fixing means such as adhesion and spot welding depending on the shape, etc., which makes it easy to form the inner and outer metal plates, and makes it possible to reduce the size of the space. It can be easily and inexpensively manufactured with uniform thickness in each part. In particular, in the double folding plate material of the present invention, at least 1! Since the structure has an extended connecting part made of only an outer metal plate having a peak part of I and an inclined part continuing to the outside, it is necessary to connect the double folding plate material laterally. One side i of the folding plate material
It is possible to easily polymerize the connecting parts of other adjacent double-folded plates from above the parts without causing them to tangle with each other.
At this time, the connecting part made of the outer metal plate has a mountain part and an inclined part continuous to this part, so that it covers the side I & part of the other double-folded plate material, so there is a risk that rainwater etc. may enter through the connecting part. In addition, since the space between the inner and outer metal plates is continuously formed between adjacent double-folded plates, the insulation and strength characteristic of double-folded plates can be sufficiently maintained even at the joints. It can be retained. Furthermore, in the double prayer plate material of the present invention, by making it a standard length material with at least the dimension in the direction of the hanging hand as a default value, handling, portability, construction workability, and economic efficiency are improved. The inner and outer metal plates having peaks and troughs are shifted from each other by one peak in the width direction and then overlapped to form an outer connecting part and an inner connecting part. The production cost can be further reduced by using the corrugated plate material for folding plates almost as is.
