DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double folded plate roof in which a heat insulating material, a sound absorbing material and the like are filled between an upper plate and a lower plate.

[0002]

2. Description of the Related Art There is a double folded plate roof in which a heat insulating material, a sound absorbing material and the like are filled between an upper folded plate and a lower folded plate. This double-folded roof has a configuration in which the heat insulating material, the sound absorbing material, etc. are sandwiched between the upper folded plate and the lower folded plate, and the heat insulating material, the sound absorbing material, etc. are sandwiched between the upper folded plate and the lower folded plate. Can be held for a long time.

[0003] The folded plate constituting the double folded plate roof is made of a thin steel plate having an arbitrary length, and has a U-shaped cross section so that a peak and a valley are continuous.
Alternatively, the ends of the folded plates formed in a V-shape are overlapped and joined by bolts, or the ends are provided with compaction and joined together to join the adjacent folded plates and roof the roof Things. However, since the folded plate is manufactured by molding a thin steel plate, it is necessary to provide a heat insulating material. As a method of providing the heat insulating material on the folded plate, the heat insulating material is integrally molded with the folded plate, the heat insulating material is adhered to the back of the folded plate, or the heat insulating material is sprayed on the back of the folded plate, A reliable heat insulating effect cannot be expected for a long period of time, for example, the heat insulating material provided due to aging or the like cannot be peeled off from the folded plate, and the heat insulating material provided on the back surface cannot be provided thickly and has a small heat insulating effect.

[0004] In order to solve this, there is a structure of a double folded plate roof. As shown in FIG. 4, this double-folded roof is composed of an upper folded plate and a lower folded plate. The lower folded plate is installed on a tight frame fixed on a beam, and the lower folded plate is installed. The board is locked to a tight frame, heat insulation is laid on it, and an upper folded board is laid from above. That is, a heat insulating material is filled between the upper folded plate and the lower folded plate. As described above, since the double-folded plate roof has a configuration in which a relatively thick heat insulating material can be substantially sandwiched, it is possible to maintain a long-term heat insulating effect.

[0005] As described above, the double-folded roof has a structure in which the heat insulating material, the sound absorbing material, and the like are sandwiched between the upper folded plate and the lower folded plate. It can be maintained between the side folded plates for a long time, and thus the heat insulating effect can be maintained for a long time.

[0006]

However, since the lower folded plate of the double folded roof as shown in FIG. 4 is made of a thin steel plate, the sound generated in the room cannot be absorbed and all the sound is reflected. . For this reason, the interior of a building using a double-folded roof has increased reverberation such as reflected sound, and the habitability has deteriorated. Therefore, as shown in FIG. 5, the use of a perforated metal having a hole in the lower folded plate enhances the sound absorbing effect and improves the comfort. This is because the sound generated in the room passes through the holes provided in the punched metal and is absorbed by the heat insulating material having a sound absorbing effect.

The folded plate is formed so that the crest and the valley are continuous, and each of the crest and the valley has a bent portion at a portion extending from the crest to the valley and from the valley to the crest. Insulation material filled between the folded plate and the lower folded plate cannot be filled without a gap between the upper folded plate and the lower folded plate, and the upper folded plate and the lower folded plate have respective bent portions. There will be gaps. For this reason, the gap formed in the bent portion is condensed, and when the lower folded plate is a perforated metal having holes, water droplets generated by the condensation fall into the room from the holes, and the beam inside the building is However, there is a problem in that when the building is a factory, the machinery and the like are contaminated and rust is generated.

In the case where the heat insulating material filled between the upper folded plate and the lower folded plate easily absorbs water, it absorbs water in the air together with water droplets generated by dew condensation. Water droplets are formed between the material and the lower folded plate, and when the lower folded plate is a perforated metal having a hole, the water droplet cannot be drained to the outside of the building and falls into the room, causing a similar problem.

As described above, since the lower folded plate of the double folded roof is a thin steel plate, it can be drained but cannot absorb sound, so there is a problem of reverberation such as reflected sound. Has a problem that it can absorb sound but has holes and cannot be drained.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide an architectural plate material capable of improving the sound absorbing effect and draining water droplets generated by dew condensation or the like.

[0011]

SUMMARY OF THE INVENTION Therefore, the present invention provides a double-folded roof in which a heat insulating material and a sound absorbing material are filled between an upper folded plate and a lower folded plate. A large number of holes of an arbitrary size are provided in the plate, a bent piece bent in the direction of the outer folded plate is formed in the hole, and a gutter is provided in a valley of the lower folded plate. Things.
