Description

TECHNICAL FIELD The present invention relates to a metal face plate for construction, and more specifically,
A metal that has been improved to give soundproofing and sound insulation properties to a horizontal roofing board and a vertical roofing board for a metal roof structure in a building, or a building metal face plate used for a metal exterior structure exterior plate and a wall panel, etc. It is related to the exterior plate made of.

[Conventional technology]

Conventionally, as a method of improving the soundproofing and soundproofing properties of a metal exterior plate having a face plate portion that mainly forms the surface mounting portion of this kind of a thatched roof plate, a thatched exterior plate, etc. A means has been widely adopted in which a sound-absorbing material and a sound-insulating material are laid on the entire surface of the base side, and the sound-absorbing material and sound-insulating material serving as the underlays perform the functions of sound absorption and sound insulation.

[Problems to be Solved by the Invention]

However, an indirect means of merely bringing the sound absorbing material and the sound insulating material into contact with the back surface of such an exterior plate directly vibrates when an external force is applied to the face plate portion of the metal face plate member exposed on the surface portion. The metal face plate member itself serves as a noise source and is based on the idea of absorbing and insulating this noise, and does not prevent the generation of noise itself.

On the other hand, means for adhering a sound absorbing backing member made of a material having a relatively low surface density such as foamed polyurethane foam to the entire back surface including the face plate portion, or a backup material being pressed and adhered so as to follow In addition, it is considered that the metal face plate member itself is formed of a so-called vibration damping steel plate such as a resin laminated steel plate, but it is not suitable as a product that can be provided at low cost because it becomes complicated in accuracy or manufacturing. .

Therefore, the present invention has been made in view of the above-mentioned conventional problems.
Even in the case of a metal exterior plate, it is most effective for improving the soundproofing mainly due to the vibration damping effect to the part that is most likely to vibrate and generate noise, that is, the face plate part that is the main part of the mounting part. The purpose is to provide a metal exterior plate that has been subjected to practical noise prevention measures.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the metal exterior plate according to the present invention has a face plate portion which is a main part of the mounting portion, and each side edge portion in the width direction of the face plate portion is attached to the base material side. In a metal exterior plate having an engagement portion for fastening, a thin backing member made of a material having an areal density different from that of the material of the exterior plate is provided, and the face plate part Each of these backing members is adhered to the back surface of the sheet at a required interval.

[Action]

That is, in the present invention, a backing member made of a plurality of thin materials made of a material having an areal density different from that of the material of the exterior plate is provided, and each of these backing members is provided on the back surface of the face plate portion. Since the backing members are adhered to each other at the required intervals, the face plate portion alone is not necessary for the backing members consisting of a plurality of masses on each balanced surface portion of itself. Imbalance due to spaced attachments. Therefore, as a result of the non-uniform natural frequency in each part of the surface, only the face plate part of the exterior plate without the backing member has the mass of each part of the surface in the equilibrium state, so that the entire surface is integrated and continuous. That the natural vibrations and initial vibrations of the face plate itself that were generated due to the difference in the natural frequency and imbalance between the surface parts caused by the attachment of the backing member directly cancel each other out. Therefore, it is possible to positively and effectively suppress the generation of noise, which is the generation of the overall vibration of the face plate portion. That is, as a result of the vibration damping effect of the above configuration, the soundproofing property can be significantly improved.

Further, due to the vibration of the metal face plate portion, when the backing member made of a plurality of sheets adhered at the above-mentioned interval is polyester or the like, the polyester is deformed and the vibration of the face plate portion is converted into heat energy. Therefore, it is possible to suppress the noise generation accordingly.

By processing by roll forming or the like, a face plate portion (2) having a required appropriate surface area is left in the center portion in the width direction, and the eaves side forming portion (3) is provided at one side edge portion thereof and the other side surface portion is provided. The ridge-side molding portions (4) are formed on the side edge portions in a predetermined cross-sectional shape.

Each of these molding parts (3) and (4) is formed by adjoining either the eaves side or the ridge side corresponding to the front-back width direction (vertical width direction in the case of an exterior plate). The roof surface can be raised as in the initial stage by interlocking the other molded portion with the other portion and retaining and fixing the other molded portion to the roof substrate side with a predetermined suspending member or the like.

Regarding the face plate portion (2), according to the material, thickness, toughness, and molding mode of the metal thin steel plate used as the material, the surface area of the face plate portion is determined from the set effective surface area. A predetermined natural frequency (A) is given to the whole.

(11) is a backing member formed of a heterogeneous material having a natural frequency (A) different from the natural frequency (A) of the face plate portion (2) of the horizontal roofing plate (1), Material (1

Therefore, in the first embodiment configured as described above, when looking through the entire surface portions of the face plate portion (2), each portion that has a natural frequency (A) in series before the attachment is , The first backing member (12) having a natural frequency (B) at a predetermined position separated by a required distance (21) on the back side thereof is integrally attached, so that only the attached portion is The natural frequency changes to a natural frequency (A, B) that is a combination of both natural frequencies (A) and (B).

As a result, each thatched roofing board constructed in this way (1)
In a horizontal thatched roof structure that has been raised by the above method, when the roof surface, and thus the face plate portion (2), is subjected to a collision pressure such as raindrops or hail, or a wind abrasion pressure,
Since the natural frequencies (A) and (A, B) of the portion where the first backing member (12) is adhered and the portion where this is not adhered are different from each other, The natural vibrations that have been generated in a series on the entire surface of the face plate part (2) due to the imbalance of the mass of each surface part are the natural frequencies (A) between these surface parts. , (A, B) will be directly canceled by the difference.
The generation of noise as the whole vibration of the face plate portion (2) is positively and effectively suppressed. That is, the sound damping property can be significantly improved by the vibration damping effect.

In addition, in the configuration of the first embodiment, regarding the attachment mode of the plurality of first backing members (12) to the back surface of the face plate portion (2) of the thatched roof plate (1), the first embodiment will be described. The backing member (12) can be set to a required length, respectively, and can be deformed and arranged as shown in FIGS. 2 (b) to (f).

That is, the attachment mode of FIG. 2 (b) is the backing member (12).

Are alternately arranged and attached. In each of the first backing members (12a) and (12b) having different widths,
Since the natural frequencies (Ba) and (Bb) of each of them slightly deviate from each other and do not match each other, even in this case, the overall vibration of the face plate portion (2) can be suppressed even more effectively. Of.

In the case of the configuration of the third embodiment shown in FIG. 4, in the configuration of the first embodiment, the first backing member (12) (using a rubber sheet) and the natural frequency of the natural frequency (B) are used. (C)
The second backing member (13) (which uses a vinyl chloride sheet) and the second backing member (13) are alternately arranged and adhered in the same manner as in the previous example, and due to the difference in natural frequency between them,
Here again, the overall vibration of the face plate portion (2) can be suppressed even more effectively.

〔The invention's effect〕

As described in detail above, according to the present invention, a backing member composed of a plurality of thin materials made of a material having an areal density different from that of the material of the exterior plate is provided, and Since these backing members are adhered to each other with a required gap, the face plate portion alone is used as a backing member consisting of a plurality of masses at each balanced surface portion. The patch members are affixed to each other at a required distance from each other to cause an imbalance. Therefore, as a result of the non-uniform natural frequency in each part of the surface, only the face plate part of the exterior plate without the backing member has the mass of each part of the surface in the equilibrium state, so that the entire surface is integrated and continuous. That the natural vibrations and initial vibrations of the face plate itself that were generated due to the difference in the natural frequency and imbalance between the surface parts caused by the attachment of the backing member directly cancel each other out. Therefore, it is possible to positively and effectively suppress the generation of noise, which is the generation of the overall vibration of the face plate portion. That is,
As a result of the vibration damping effect produced by the above construction, it is possible to remarkably improve the soundproofness.

Further, when the backing member made of a plurality of sheets adhered at the above-mentioned interval is made of polyester or the like due to the vibration of the metal face plate portion, the polyester is deformed and the vibration of the face plate portion is converted into heat energy. Therefore, it is possible to suppress the noise generation by that amount.

Further, as described above, the structure in which the backing member is adhered to the back surface of the face plate portion, that is, the structure in which the backing member is partially adhered to a required portion makes ,
Effective soundproofing, which is completely different from the case of interposing a base material such as backup material or cushioning material, or adding a material layer such as a urethane foam layer to the back surface of the roofing roof itself. Alternatively, it can exhibit sound insulation.

Furthermore, by partially adhering the backing member to the required portion, the material consumption of the intervening member on the base side can be reduced, which contributes to the simplification of the structure and the ease of manufacturing. It has excellent features such as helping to reduce costs.
