Description

TECHNICAL FIELD The present invention relates to a metal face plate for construction, and more specifically,
Improvements of horizontal roofing and vertical roofing boards for metal roof structures in buildings, or building metal face plates used for metal exterior structure exterior walls and wall panels, especially in the form of blocks in the longitudinal direction A metal face plate with a surface design having a face plate part formed by alternately subjecting the face plate concave portion and the face plate convex portion by subjecting it to concave and convex processing, and forming locking gobs on both side edges in the width direction of the face plate portion. In the member, the present invention relates to a construction metal face plate improved so as to provide at least soundproofing and sound insulating properties to the faceplate portion.

[Prior Art] Conventionally, in a surface structure using this type of building metal face plate, a lateral thatched roof plate, a vertically roofed roof plate, or an exterior plate, which is used for the surface structure material, is exposed on the surface portion thereof. In the face plate part in the normal form metal face plate member such as a wall panel,
As a method of improving the soundproofing and sound insulation properties, generally, prior to the tensioning of the metal face plate member, a sound absorbing material and a sound insulating material by another sheet-shaped member are laid on the entire surface of the base side, and It is widely adopted that the sound-absorbing material and the sound-insulating material serving as the underlay play their respective roles, that is, the means for fulfilling the respective functions of sound-absorbing and sound-insulating.

Further, as the metal face plate member, conventionally, there is a face plate portion formed by alternately subjecting a face plate concave portion and a face plate convex portion to form a block shape in the longitudinal direction, and the width direction of the face plate portion. The locking edge was molded on the side edge,
A metal face plate member with a so-called surface design is known,
The alternately continuous face plate recesses and face plate protrusions in this metal face plate member are formed mainly to enhance the appearance design of the metal face plate member itself, but secondarily,
In addition to absorbing the pocket wave (that is, the so-called strain of the material itself) that occurs on the metal surface when forming the goby, it also has the effect of giving stronger rigidity to the face plate itself. Even for the metal face plate member, the same means as described above is adopted as a method for improving the soundproofness and sound insulation.

[Problems to be Solved by the Invention]

However, in the former or the latter, the sound absorbing material and the sound insulating material are simply brought into contact with the respective rear surface sides of the respective metal face plate members, which is a so-called indirect means. In the case of the face plate portion exposed to the surface portion of the surface structure of the metal face plate member in, in particular, the face plate portion exposed to the surface portion of the surface structure of the metal face plate member in the latter form with surface design In this case, since the face plate concave portions and the face plate convex portions formed by the concavo-convex processing are alternately continuous, the adhesion to the underlying sound absorbing material and sound insulating material is extremely poor. In the portion corresponding to, the convex portion of the same surface plate is lifted from the surface of each of these sound absorbing materials and sound insulating materials to form a relatively large space portion, and as a result, due to this space portion, it is externally exposed. On the exposed face plate And, rainfall, when external impact such as hail are added, in relation to the space portion formed therein, and this ゝ is similar as in the one drum action,
There is a problem that the effect is produced and relatively large noise is generated.

Therefore, the object of the present invention is to form the face plate concave portion and the face plate convex portion by subjecting the concave-convex processing alternately to form a block shape in the longitudinal direction in view of the above-mentioned conventional problems. In a metal face plate member with a so-called surface design, which has a face plate portion and has locking gobs formed on both side edges in the width direction of the face plate portion, the most likely place to vibrate and generate noise. It is an object of the present invention to provide a metal face plate for construction of this kind in which effective and practical noise prevention measures are taken for the face plate portion composed of the face plate concave portion and the face plate convex portion.

[Means for Solving the Problems]

According to an experiment conducted separately by the inventor in order to achieve the above object, the material of the metal face plate member is different from the face plate concave portion and the face plate convex portion in the face plate portion of the metal face plate member with the surface design. When a backing member made of a material having an areal density different from the areal density is pasted, even if the width of the backing member is less than the full width of the face plate, It was confirmed that the noise prevention effect was more than reasonable.

That is, the present invention has a face plate portion formed by alternately subjecting the face plate concave portion and the face plate convex portion to form a block shape in the longitudinal direction, and at both side edges in the width direction of the face plate portion. In a metal face plate member having a locking gob formed, a sheet-like backing member having a surface density different from that of the material of the metal face plate member and having a width narrower than the width of the face plate part is used. A metal plate for construction, characterized in that a backing member is provided, and the backing member is continuously adhered to the back surface of each of the recesses and the projections of the face plate through the middle portion in the width direction.

[Action]

That is, in the present invention, there is a face plate portion formed by alternately subjecting the face plate concave portion and the face plate convex portion so as to form a block shape in the longitudinal direction, and both side edges in the width direction of the face plate portion. In a metal face plate member having a locking gob part formed on the locking member, a material having an areal density different from that of the material of the metal face plate member is used, and a sheet-like member having a width narrower than the width of the face plate part is used. The backing member is provided, and the back surface of each of the face plate concave portion and the face plate convex portion is passed through the widthwise approximately middle portion of the back surface,
Since the backing member is continuously adhered, the occurrence of noise due to individual vibrations of each face plate concave portion and face plate convex portion is reduced by the width direction of the back surface of each face plate concave portion and face plate convex portion. It can be suppressed by the backing member that is continuously attached through the intermediate portion.

〔Example〕

Examples of the metal plate for construction according to the present invention will be described below.
This will be described in detail with reference to FIGS. 1 to 3.

FIG. 1 is a partial cross-sectional perspective view showing a schematic configuration of a horizontal thatched roof plate member when the metal face plate for construction of the present invention is applied to a lateral thatched roof structure, and FIGS. 1 is an enlarged cross-sectional view taken along line II-II and line III-III of FIG. 1, respectively.

That is, in each of the drawings of these Examples, reference numeral (1) represents a horizontal thatched roof plate member as a metal face plate member, and the lateral thatched roof plate member (1) has a block shape in the longitudinal direction. It has a face plate portion (2) which is formed by alternately subjecting the face plate concave portion (3a) and the face plate convex portion (3b) to each other, and the width of the face plate portion (2). Goby portions (4a) and (4a) for locking on both side edges in the direction, that is, on the side edges corresponding to the eaves side and the ridge side in this case.
b) is formed into a predetermined cross-sectional shape. As is well known in the art, the eaves side and ridge side goby portions (4a) and (4b) corresponding to the width direction are not , The other goby part is mutually engaged with one of the goby parts arranged adjacent to the eaves side and the ridge side, and is fixed and fastened to the roof base side with a predetermined hanging member or the like. , The metal surface structure is the same as the initial one. In this case, the roof surface is raised.

As described above, the face plate concave portion (3a) and the face plate convex portion (3b) which are alternately connected in the longitudinal direction in the horizontal thatched roof plate member (1) are mainly the same as described above. While being formed to enhance the appearance and design of the metal plate member itself, it absorbs the pocket wave (strain of the material itself) that occurs on the metal surface as a side effect when forming each goby portion (4a) and (4b). At the same time, each of the face plate recesses (3a) and the face plate protrusions (3b) and the periphery of the face plate protrusions (3b), and thus the face plate part (2) itself, are provided with stronger rigidity.
When looking at each of the face plate convex portions (3b), the face plate concave portions (3a) are formed in such a manner that a flat plate surface that easily causes free vibration is formed on the peripheral portion having high rigidity. ) And the face plate convex portion (3b) have a predetermined natural frequency (A) from the surface density, the plate thickness, the toughness, the size of the effective surface area set therefor, etc. depending on the material of the thin metal sheet used. ) And (B).

Further, (5) is a backing member formed of a heterogeneous material having an areal density different from the areal density of the metal material in the face plate part (2) of the roofing roofing plate member (1). The backing member (11) has a thickness corresponding to the material used, for example, the face plate portion (2) as described later.
The natural frequency (A) of each face plate concave portion (3a) and face plate convex portion (3b) at the pasted portion in the state where the face plate concave portion (3a) and the face plate convex portion (3b) are pasted together. (B) made of a material that can be sufficiently changed, for example, a rubber plate, a rubber sheet having a specific natural frequency (C) which is different from the natural frequencies (A) and (B). A vinyl chloride plate, a vinyl chloride sheet or the like is used, and its shape and size are set to a required length that is sufficiently thicker and narrower than the thickness and width of the face plate portion (2). In this embodiment, a rubber sheet having a natural frequency (C) is used as the material to be used, and a width narrower than the width of the face plate portion (2), for example, a width of about 1/2 is prepared. To do.

Therefore, in the configuration of this embodiment, as shown in each drawing, the face plate concave portion of the natural frequency (A) forming the face plate portion (2) of the lateral thatched roof plate member (1). (3
a), and the natural frequency (B) at a predetermined position in the width direction, for example, in the middle portion in the width direction, through the entire back surface of the face plate convex portion (3b) having the natural frequency (B). The backing member (5) having a width of about 1/2 is attached in series so as not to easily fall off, and both of them are integrated.

Therefore, in the embodiment configured in this way, the surface plate concave portions (3a) and the surface plate convex portions (3b) forming the face plate portion (2) of the horizontal roofing plate member (1) are respectively surface portions. When looking through the whole of the above, the natural frequencies (A) and (B) before the backing member (5) is attached are the natural frequencies (C) obtained by passing through the respective predetermined positions on the back surface in series. The backing member (5) having a width of about 1/2 has a natural frequency, and its natural frequency is combined with the natural frequencies (A), (B) and (C). Natural frequency (A,
C) and (B, C), and as a result, in the side-roof structure that was raised by each side-roofing roof plate member (1) constructed in this way, the roof surface, and by extension, , When an external impact such as rainfall or hail from the outside, an external pressure of rubbing wind, etc., is continuously applied to the face plate portion (2) including the face plate concave portion (3a) and the face plate convex portion (3b), The natural frequencies (A), (A, C) and (B), (B, C) of the part where the backing member (5) is not attached and the part where this is attached are Since they are different from each other, the mass of each surface portion is unbalanced, and conventionally, the face plate concave portion (3a) and the face plate convex portion (3b) are conventionally formed.
Frequency (A) and (B) generated on each surface of
Each natural vibration of is directly canceled by the difference of natural frequencies (A), (A, C) and (B), (B, C) between these surface parts. Here, as a result, the vibration of the entire face plate portion (2), in other words, the generation of noise is positively and consequently suppressed.

In addition, the selection criteria of the natural frequencies (A) and (B) of the face plate concave portions (3a) and the face plate convex portions (3b) and the natural frequency (C) of the backing material (12) are described above. In addition to the difference in surface density between the two, it is possible to select on the basis of the difference in specific gravity between the two, and this can also achieve the same action and effect.

In addition, as shown in the experiment by the present inventor, the width of the backing member (5) is approximately 1 / the width of each of the face plate concave portions (3a) and the face plate convex portions (3b) forming the face plate portion (2). When set to about 2, the noise level generated when the backing member (5) was attached as described above against the noise level generated when the backing member (5) was not attached It was confirmed that a value of about 75% could be obtained, assuming that the decrease rate was 100%. In particular, the noise reduction in this case was more prominent in the high frequency range that was most annoying to humans living inside the building.

Even when the width of the backing member (5) is set to about 1/4, the noise level is reduced by about 60%, and thus the face plate recesses (3a) and face plate protrusions (3a) It was fully demonstrated that the attachment of the backing members (5) having different surface densities over the entire back surface of 3b) was extremely effective or characteristic for noise suppression.

On the other hand, each face plate concave portion (3a) and face plate convex portion (3b)
Regarding the attachment position of the backing member (5) with respect to the back surface of the plate, as seen in the configuration of this embodiment, the vibration center portions of the face plate concave portions (3a) and the face plate convex portions (3b) that are also the vibration generating surfaces, That is, it is effective to be the middle portion in the width direction, but depending on the given cross-sectional shape, the center of vibration may not always be located in the center of the width direction.
It is desirable to select and attach the vibration center part as much as possible, or alternatively, to select and attach the node corresponding part of the vibration wave propagating due to the vibration generation.

In the configuration of the embodiment, the case of applying to a horizontal thatched roof plate for a thatched roof structure as a metal plate for construction was described, but a vertically thatched roof plate for a thatched roof structure,
Of course, it can be applied to the exterior plate for the exterior structure, the wall panel, and the like in the same manner, and the same action and effect can be obtained.

〔The invention's effect〕

As described in detail above, according to the present invention, it is used for a horizontal roofing board and a vertical roofing board for a roof structure in a building, or an exterior board and a wall panel for an exterior structure, and blocks in the longitudinal direction. A metal having a face plate part formed by forming concave and convex face plate parts by subjecting the plate to a concave-convex process alternately so as to form a shape, and forming a locking gob part on both side edges in the width direction of the face plate part. In the face plate member, a material having an areal density different from that of the metal face plate member is used, and a sheet-like backing member having a width narrower than the width of the face plate portion is provided, and each face plate recess and face plate are provided. Since the backing member was continuously attached through the middle part of the back surface of the convex part in the width direction, the noise generated by each vibration of each face plate concave part and face plate convex part And width of the back surface of the convex part of the face plate Due to the backing member that is continuously attached through the approximately middle portion, the natural frequencies of the backing members change and cancel each other out. As a result, the overall vibration of the face plate, that is, noise It is possible to positively and effectively suppress the occurrence of the above, and it has an excellent feature that it is structurally relatively simple and can be implemented easily and inexpensively.
