Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to improvements in fixed length folding plates mainly used for roofs.

[Conventional technology]

Conventionally, as the above-mentioned fixed length folding plate material, for example, Japanese Patent Application Laid-open No. 6
As shown in Publication No. 1-254737, a heat insulating material is filled between the widthwise intermediate portions of the outer metal plate in a cross-sectional shape in which peaks and valleys are alternately continued by sloped portions, Both sides of the inner and outer metal plates are brought into contact with each other, and one side edge of the inner and outer metal plates is lengthened and folded back, and the other side edge of the inner and outer metal plates are sandwiched at the folded-back part. There was something I did.

[Problem to be solved by the invention]

Conventional fixed length folding plates with inner and outer metal plates have the above-mentioned configuration, so it is impossible to form an air layer or an air passage between the inner and outer metal plates. The manufacturing process is cumbersome, as one side edge of the plate has to be lengthened to form a folded part, and there are also problems in that it is difficult to connect the fixed length folding plates in the longitudinal direction, and it is also difficult to prevent leakage at the connecting part. Ta.

The present invention was made to solve the above-mentioned problems, and it is possible to form a heat insulating layer between the inner and outer metal plates.
Another object of the present invention is to provide a fixed length folding plate material that can be easily connected in the longitudinal direction, prevents leakage at the connecting portion, is easy to manufacture, and can be obtained at low cost.

[Means to solve the problem]

The fixed-length folded plate material of the present invention has a cross-sectional shape in which peaks and valleys are alternately continued by sloped parts, and the potting blades are slightly shifted, and at one end, the inner metal plate is replaced by the potting plate. At the other end, the potting wing plate is made to protrude from the inner metal plate, and a space is formed between the inner potting wing plates over the entire surface of the lid part where the inner potting wing plates overlap. The inner and outer metal plates are fixed via a partition retaining member provided inside the section.

Further, in the present invention described above, the spacing member is provided at one or two of the peaks, valleys, and slopes within the space.

[Effect]

In the regular folded plate material of the present invention, a space is formed between the inner and the interlocking blades over the entire area where these metal plates overlap, so this space can be used as a heat insulating layer. ,
Since the potting blades are separated by the space at both ends in the longitudinal direction, and the inner potting blades are shifted,
The inner metal plate is used with the end protruding from the potting wing plate facing upwards, and the lower end of the potting wing plate is placed downward among the fixed length folding plates placed above the connecting part. By stacking and supporting each of the folded plates on the two-line parts of the pot joint plates, the inner metal plates overlap more than the parts where the pot plate plates of the upper and lower fixed length folding plates overlap. Since the portion is located upward (see FIGS. 4 and 5), the fixed length folding plates can be easily connected in the longitudinal direction without causing problems such as leakage.

Further, the present invention provides a method for fixing the inner pot joint blade plate via a spacing member provided at one or two of the peaks, troughs, and slopes of the space. It is easy to form the inner and outer fitting blades because the spacing member and the inner and outer fitting blades can be fixed by appropriate means such as adhesion, spot welding, and foam filling depending on the material and shape of the holding member. Coupled with this, it is possible to easily and inexpensively manufacture a space in which the thickness of each part is uniform, and furthermore, the space can be used as an air passage or a heat insulating air layer.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

, (2a), short inclined parts (ld) and (2d) are bent respectively. In addition, the inner metal plate (1) is made of a relatively thick and strong steel plate, etc., and the pot joint plate (2) is a stainless steel plate that is relatively thin and has a lower strength than the inner metal plate (+). It is made of a metal plate made of a material that does not easily corrode, such as a copper plate.

The inner metal plate (1) and (2) are formed to have the same length and are slightly shifted in the longitudinal direction.
The upper (stock system) end (11) is located above the potting wing plate (2) (
It protrudes from the end of the pot joint (2) and below (on the eave side)
The end portion (2□) protrudes from the lower (eave side) end of the inner metal plate (1).

In FIG. 1, (1□) indicates the lower end of the inner metal plate (1), and (2I) indicates the upper end of the potting wing plate (2). A space (3) is formed over the entire surface in the area where these overlap between the inner and matching blades (1) and (2), and this space (3) is made to have a uniform thickness at each part. A spacing member (4) is provided in each of the peaks (3a) and troughs (3b) of the space (3), and the inner and outer pot joint blades (1) are provided through the spacing members (4). ) and (2) are fixed, and no spacing member is provided on the inclined portion (3C) of the space portion (3). That is, the spacing member (4) is made of a plate-like material such as hard plastic, hard cardboard, or metal plate, and has an inclined portion (
4b), (4b) is bent. Surface support part (
In 4a), the inner potted blade plates (1) and (2) are the space part (
3) Yamabe (LA) via.

(2a) and the troughs (ib) and (2b) are formed to have a width (A) approximately equal to the width (a) of the opposing short sides, and the interval (B) between the tips of the sloped portions (4b) and (4b) is, inside,
The pot joint blades (1) and (2) connect to the mountain part (

The width (b) of the opposite long side is approximately equal to the width (b) of the opposite long side.

The spacing member (4) has an inclined portion (4b).

The inclined parts (lc) of the pot joint blades (1) and (2) are continuous with the tips of (4b) on the long sides and both sides of these long sides.
, (2c) (or short slope (ld), (2

2), the inclined portion (4b), the tip of (4b), and the support portion (4a) are bonded or welded to the opposing surfaces of (2).

Furthermore, in the inclined part (3C) of the space part (3), a heat insulating and sound absorbing material (5
) are filled with these inside.

The pot joint blade plates (1) and (2) are fixed.

The fixed-length folded plates of the embodiments constructed as shown in FIG.

In this case, the connection in the vertical (needle line) direction is achieved by using a regular folding board (7, The lower (eave side) ends (1

Standard folding plate material (71), metal plate (1) inside (7□).

(1) Position the parts where they overlap closely. In this way, as shown by the solid arrow in Figure 3,
Due to the slope of the roof, water such as rainwater flowing through the potting blades (2) and (2) is difficult to enter inside through the overlapped portion of the potting blades (2) and (2). In addition, the wind blowing up from the eaves traps rainwater, etc., on the wing plates (2) and (2).
) Even if it goes slightly inside through the gap, the pot joint wing plate (2>, (2
) overlaps the inner metal plate (1), (1
) is located above (on the line side), so rainwater does not enter inside the area where the inner metal plates (1) and (1) overlap. Even if a small amount of water such as rainwater enters the inside of the pot joint plate (2), (2), it will flow over the inner metal plate (1), (1) and move further downward from the lower (eave side) end. Water can be led onto the inner metal plate (1) of the regular folding plate material connected to the (eave side) and drained to the outside, so that no rain leaks from the connecting part of the regular length folding plate material. In addition, the inner potted wing plate (l).

The space (3) between (2) is thermally insulated by connecting regular folding plates in the vertical (needle line) direction.

In addition to soundproofing, it can also be used as an air passage, as warm air in the summer flows toward the line side as shown by the broken line arrow in Figure 3.
Air can be prevented from stagnation in the space (3). Furthermore, when using the regular folded plate material of this example on a roof in a snowy area, by making the spacing member (4) strong, it is possible to ), (2
) peaks (Ia), (2a) and valleys (lb)
.

By forming a box-shaped cross section with the long sides of (2b), a roof that can withstand the weight of snow can be obtained.

In addition, in the present invention, the spacing member (4) is not necessarily limited to that of the above-described embodiment, and may be modified as appropriate, such as a structure in which a plurality of vibrator materials are closely arranged in parallel. The length may span the entire length of the space where the inner and outer metal plates overlap, or it may be arranged at appropriate intervals at multiple locations in the longitudinal direction of the space. It may be provided only on the peaks and valleys of the plate. In the present invention, when the spacing member is used, the heat insulating and sound absorbing materials are not limited to foam materials, and glass wool or the like may be used, and the heat insulating and sound absorbing materials do not necessarily have to be used. .

Further, the present invention provides a method of foam filling the entire space between the inner potting plates or one or two of the inclined portions, peaks, and troughs, and filling the foamed material with the spacing member. In this case, the spacing member (4
) may not be used. Further, the fixed length folding plate material of the present invention is
It can be used not only for roofs but also for the exterior walls of buildings.

〔Effect of the invention〕

As explained above, according to the present invention, since a space is formed between the inner and outer metal plates over the entire area where these metal plates overlap, this space can be used as a heat insulating layer. The inner and outer metal plates are separated by the space at both ends in the longitudinal direction, and the inner and outer metal plates are staggered, so that the end of the inner metal plate protruding from the outer metal plate is placed on one side. The lower end of the outer metal plate of the fixed length folding plate placed above the connecting part is overlapped with the upper end of the outer metal plate of the fixed length folding plate placed downward. By supporting the upper and lower fixed length folding plates, the parts where the inner metal plates overlap each other are more secure than the parts where the outer metal plates overlap.
It is located in the L direction, and therefore, there is an effect that the fixed length folding plate materials can be easily connected in the longitudinal direction without causing problems such as leakage.

Further, the present invention provides a method for maintaining the distance by fixing the inner and outer metal plates via a distance maintaining member provided at one or two of the peaks, troughs, and slopes of the space. The spacing member and the inner and outer metal plates can be fixed together by appropriate means such as adhesion, spot welding, foam filling, etc. depending on the material and shape of the member, which makes it easy to mold the inner and outer metal plates. It is possible to easily and inexpensively produce a regular folded plate material in which the thickness of the space is uniform in each part, and furthermore, the space can be used as an air passage or a heat insulating air layer.
