DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure having a folded plate in which peaks and valleys are alternately bent, and a damping folded plate roof cover used in the roof structure.

[0002]

2. Description of the Related Art As a conventional roof structure using a folded roof cover of this type, the one shown in FIG. 7 is known.

In such a structure, the roof 1 mainly comprises
Folded plate 2 and flat material 3 arranged on the upper surface side of this folded plate 2
And a reinforcing support member 4 that supports the flat member 3 by being interposed between the folded plate 2 and the flat member 3.

[0004] Among them, a folded plate 2 formed by bending a steel plate.
Are alternately provided at substantially equal intervals with peaks 5, 5 and valleys 6.

[0005] On the left and right sides of the peak 5, arcuate bulges 7, 7 are provided as fitted parts. The upper end of a tight frame (not shown) is attached to the bulge 7, 7 is fitted.

The reinforcing support member 4 is formed by bending a sheet of vinyl chloride resin-coated steel sheet, and has a flat plate portion 8 in contact with the flat plate member 3 and protrudingly provided on both left and right sides of the flat plate portion 8. And a pair of leg portions 9, 9.

The leg portion 9 is a vertical piece 10 vertically hanging from a position inside a predetermined width from a side edge of the flat plate portion 8.
And an inclined piece 11 extending obliquely upward from the lower end of the vertical piece 10 toward the outside, and a folded piece 12 formed at the tip of the inclined piece 11 and folded inward. .

Next, the operation of this conventional device will be described.
In the conventional device configured as described above, first, the reinforcing support member 4 is mounted between the valleys 6 and 6 of the folded plate 2. Reinforcement support 4
By pushing the leg portions 9, 9 toward the valley portion 6, the flat plate portion 8 straddles between the ridge portions 5, 5, and the folded pieces 12, 12 are attached to the bulging portions 7, 7. It is mounted on the folded plate 2 in the fitted state (see Japanese Patent Application Laid-Open No. 2-282558).

[0009]

However, in such a conventional device, when there is rain on the flat member 3 of the roof portion 1, the striking sound caused by the contact of the rainwater is generated by the reinforcing support member 4.
And transmitted to the folded plate 2 to enter the room from the roof structure such as the tight frame.

For this reason, it is conceivable to suppress the increase of the approach sound by attaching a vibration damping sheet to the entire back surface of the folded plate 2. In this case, the vibration damping sheet is
Since the valleys 6 are alternately formed on the entire back surface of the folded plate 2, there is a problem that the area of the vibration damping sheet increases and the manufacturing cost increases.

For this reason, even if rainwater or the like comes into contact due to rainfall or the like and hits the flat plate portion to produce an impact sound, the impact sound is
Vibrations transmitted by the damping material provided on the damping folded plate roof cover are absorbed and do not echo.

Therefore, the possibility that the hitting sound is transmitted to the folded plate as in the related art, and the risk of entry into the room from the roof structure such as the tight frame is reduced.

Moreover, compared with the case where the vibration damping sheet is provided on the entire back side of the folded plate, the area to be stuck can be reduced, so that good sound insulation performance can be exhibited while suppressing an increase in manufacturing cost. I can do it.

According to the second aspect of the present invention, the vibration damping material is provided on a rear surface of the flat plate portion on which the legs protrude. Features.

According to the second aspect of the present invention, since the damping material is provided on the rear surface of the flat plate portion on which the legs protrude, rainwater or the like directly comes into contact. Therefore, the durability of the vibration damping material can be improved.

Further, by effectively attaching the apparatus to a flat plate portion where the impact sound of rainwater resonates, it is possible to further suppress an increase in manufacturing cost.

Further, according to the third aspect,
The roof structure according to claim 1, wherein the damping material is disposed between the roof structure upper panel and the flat plate portion.

According to the third aspect of the present invention, the vibration damping member is disposed between the roof structure upper panel and the flat plate portion. Vibration transmitted from the upper panel in the direction of the folded plate is reduced by being absorbed by the damping material.

For this reason, the risk of rainwater hitting sound or the like entering the room from below the roof structure such as a tight frame adjacent to the folded plate is reduced, and good sound insulation performance can be obtained.
