Description

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 member and a lower plate member.

[0002]

2. Description of the Related Art There is a double fold plate roof in which a heat insulating material, a sound absorbing material and the like are filled between an upper fold plate and a lower fold plate. This double folded board roof has a structure in which a heat insulating material, a sound absorbing material, etc. are sandwiched between an upper folded plate and a lower folded plate. It can be retained for a long time.

A folded plate which constitutes a double folded plate roof is a thin steel plate having an arbitrary length and has a U-shaped cross section so that peaks and valleys are continuous.
Alternatively, the ends of folded plates bent into a V shape can be overlapped and joined with bolts, or the ends can be provided with a zipper for compaction and connection, and adjacent folded plates can be connected together to roof the roof. It is a thing. 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 formed with the folded plate, the heat insulating material is adhered to the back surface of the folded plate, or the heat insulating material is sprayed on the back surface of the folded plate. The heat insulating material provided due to aging has peeled off from the folded plate, and the heat insulating material provided on the back side cannot be thickly provided, so that the heat insulating effect is small, and a reliable heat insulating effect cannot be expected for a long period of time.

In order to solve this, there is a double folded plate roof structure. As shown in FIG. 4, this double folded plate roof is composed of an upper folded plate and a lower folded plate, and a lower folded plate is installed on a tight frame fixed on the beam. The plate is locked to the tight frame, the heat insulating material is laid on it, and the upper folded plate is formed from above. That is, the heat insulating material is filled between the upper folded plate and the lower folded plate. In this way, the double-folded plate roof has a structure in which a relatively thick heat insulating material can be substantially sandwiched, so that the heat insulating effect can be maintained for a long period of time.

As described above, since the double-folded plate 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, 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 held between the side folding plates for a long period of time, so that the heat insulating effect can be maintained for a long period of time.

[0006]

However, since the lower folded plate of the double-folded plate roof as shown in FIG. 4 is made of a thin steel plate, the sound generated in the room cannot be absorbed and is totally reflected. . For this reason, the interior of a building with a double-folded roof has many reverberations such as reflected sounds, which deteriorates the habitability. Therefore, as shown in FIG. 5, punching metal having holes in the lower folding plate is used to enhance the sound absorbing effect and improve the comfortability. This is because the sound generated in the room passes through the holes provided in the punching metal and is absorbed by the heat insulating material having a sound absorbing effect.

The folded plate is formed so that the peaks and valleys are continuous, and since the peaks and valleys each have a bent portion at a portion extending from the peaks to the valleys and from the valleys to the peaks, The heat insulation material filled between the folding plate and the lower folding plate cannot be filled without a gap between the upper folding plate and the lower folding plate. There is a gap. Therefore, if the lower folding plate is a punching metal with a hole, the water drops generated by the condensation will drop into the room through the hole and the beam inside the building will be condensed. However, there is a problem in that, when the building is a factory, mechanical equipment is contaminated and rust is generated.

When the heat insulating material filled between the upper folded plate and the lower folded plate easily absorbs water, water in the air is absorbed along with water droplets generated by dew condensation. Water drops formed between the material and the lower folding plate, and when the lower folding plate was a punching metal with holes, the water drops could not be drained to the outside of the building and fell into the room, causing the same problem.

As described above, since the lower folded plate of the double folded plate roof is a thin steel plate, it has the problem of reverberation such as reflected sound because it can drain water but cannot absorb sound. Therefore, when the lower folded plate is made of punching metal. There is a problem such as corrosion due to the drop of water drops because it can absorb sound but cannot drain because it has holes.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a building board material capable of draining water drops generated by dew condensation and the like while improving the sound absorbing effect.

[0011]

For this reason, the present invention provides a double folded board roof in which a heat insulating material, a sound absorbing material and the like are filled between the upper folded plate and the lower folded plate, and A large number of holes of arbitrary size are provided in the plate, and a bending piece bent in the outward folding plate direction is formed in the hole, and a trough is provided in the valley portion of the lower folding plate. It is a thing.

[0012]

[Function] Since the lower plate member is provided with a large number of holes of arbitrary size, and the holes are provided with the bent pieces bent in the direction of the outer folded plate, the sound generated in the room is converted into the heat insulating member having the sound absorbing effect. Since it reaches the hole, it can absorb the sound, and even if the inside of the double-folded plate roof is condensed, the condensed water is blocked from reaching the hole by the bent piece, so that it does not drop to the indoor side.

Further, since the gutter is provided in the valley portion of the lower folding plate,
Even if the inside of the double fold plate roof is condensed and the condensed water flows out, the condensed water is blocked by the bent pieces from reaching the hole, flows toward the valley and flows down into the trough, and then drains to the outside through the trough. To be done.
