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 metal face plate for construction, which is improved so as to give at least soundproofing and sound insulating properties to the face plate concave portion and the face plate convex portion.

[Conventional technology]

Conventionally, in a surface structure using this kind of building metal face plate, such as a thatched roof plate, a thatched roof plate used for the surface structure material, or an exterior material, a wall panel, etc. In the face plate portion of the metal face plate member of the form,
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 this way, in the former or the latter, the sound absorbing material and the sound insulating material are simply brought into contact with the respective back 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 sound absorbing material and the sound insulating material as the underlay 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. Pair the exposed face plate Te, rain, the impact from the outside 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, according to the material of the metal face plate member, 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 have When a backing member made of a material having an areal density different from the areal density is pasted, even if the area of this backing member is less than the area of each face plate concave portion and face plate convex portion, the natural vibration of both Based on the difference in the numbers, it was confirmed that the noise prevention effect can be exerted more appropriately.

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 the metal face plate member in which the locking gob is molded, a material having an areal density different from the areal density of the material of the metal face plate member is used, and the area is smaller than the area of each of the face plate concave portion and the face plate convex portion. A sheet metal backing member is provided, and the backing member is individually attached to approximately the center of the back surface of the face plate concave portion and the face plate convex portion of each block. Is.

[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 the metal face plate member in which the locking gob part is formed on, a material having an areal density different from that of the material of the metal face plate member is used, and an area smaller than the area of each of the face plate concave portion and the face plate convex portion. Since a sheet-like backing member is provided, and the backing member is individually attached to the center of the back surface of the face plate concave portion and the face plate convex portion of each block, each face plate concave portion is formed. Also, the occurrence of noise due to individual vibrations of each face plate convex portion can be suppressed by the backing members individually attached to the central portions of the back surfaces of these face plate concave portions and face plate convex portions.

〔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. As expected, the metal surface structure is used. In this case, the roof surface is raised.

The face plate recesses (3a) and face plate protrusions (3b) that are alternately connected in the longitudinal direction of the horizontal thatched roof plate member (1) are mainly made of the same metal as described above. While being formed to enhance the appearance and design of the face plate member itself, it also absorbs pocket waves (strains of the material itself) that occur on the metal surface during the formation of the haze portions (4a) and (4b). The face plate recesses (3a) and the face plate protrusions (3b) and the periphery of the face plate protrusions (3b), and by extension, the face plate part (2) itself, are provided with stronger rigidity.
When looking at each of a) and the face plate protrusion (3b),
It becomes as if a flat plate surface that easily generates free vibration is formed on the peripheral portion having a high rigidity, and these face plate concave portions (3a) and face plate convex portions (3b) are used materials. The predetermined natural frequencies (A) and (B) are obtained from the surface density, the plate thickness, the toughness of the material of the thin metal sheet, the size of the effective surface area set therein, and the like.

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 (5) has a thickness corresponding to the material used, for example, and has the face plate portion (2) as described later.
Of the face plate concave portion (3a) and the face plate convex portion (3b) individually attached to the back surface of the face plate concave portion (3a) and the face plate convex portion (3b) at the same attachment portion (A ) And (B) can be changed sufficiently, for example, a rubber plate or rubber having a specific natural frequency (C) which is different from the natural frequencies (A) and (B). Use a sheet, a vinyl chloride plate, a vinyl chloride sheet, etc., and have a shape and size that is sufficiently thicker and smaller than the thickness and area of each face plate recess (3a) and face plate protrusion (3b). It is preferable that a rubber sheet having a natural frequency (C) is used as the material used in this embodiment.
An area smaller than the area of each of the face plate concave portions (3a) and the face plate convex portions (3b), for example, an area of about 1/2 is individually prepared.

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 for each back surface of the convex portion (3b) of the natural frequency (B), the natural frequency (B) is provided at a predetermined position of the entire area, for example, at the central position. 1 /
Each backing member (5) having an area of about 2 is individually attached 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. Regarding, about 1/2 of the natural frequencies (A) and (B) before attaching the backing member (5) have the natural frequencies (C) to the respective back surface center positions. By attaching the backing member (5) having an area of 1 to each other by integration, the natural frequencies of these two are natural frequencies (A) and (B).
And (C) combined natural frequencies (A, C) and (B,
C), and as a result, in the side-roof roof structure that is raised by each side-roof roof plate member (1) configured in this way, the roof surface and, by extension, the face plate recesses (3a ) And the face plate convex portion (3b), the face plate concave portion (3a) when, for example, an external impact such as rainfall or hail, external wind abrasion pressure, etc. is applied without interruption. And backing member (5) on the convex portion (3b) of the face plate
The natural frequencies (A), (A, C) and (B), (B, C) of the part where is not attached and the part where this is attached are different from each other. For this reason, the mass of each part of this surface is unbalanced, and the frequencies (A) and (B) of the individual surfaces of the face plate concave portion (3a) and the face plate convex portion (3b) conventionally generated Each natural frequency is the natural frequency (A), (A,
C) and (B), (B, C) will be directly cancelled, and as a result, each face plate recess (3
The vibration through the entire a) and the face plate convex portion (3b), in other words, the generation of noise is positively and effectively 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 experiments by the present inventor, the area of the backing member (5) is approximately 1 / area with respect to the area of each face plate concave portion (3a) and face plate convex portion (3b) constituting 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 area of the backing member (5) is set to about 1/4, the noise level is reduced by about 60%.
In order to suppress noise, it is possible to individually attach backing members (5) having different surface densities to the respective back surfaces of the face plate concave portions (3a) and the face plate convex portions (3b) in this manner. It has been fully demonstrated that it is extremely effective or characteristic.

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 face plate, as seen in the configuration of this embodiment, the center of vibration of each face plate concave portion (3a) and face plate convex portion (3b) which are also vibration generating surfaces. However, depending on the given cross-sectional shape, the center of vibration may not necessarily be located at the center of area, so select the center of vibration as much as possible, or It is desirable to select and attach the node-corresponding portion 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, using a material having a surface density different from the surface density of the material of the metal face plate member, a sheet-like backing member having an area smaller than the area of each face plate concave portion and face plate convex portion is provided, Since the backing member is attached individually to the center of the back surface of the face plate concave portion and the face plate convex portion of each block, the noise generated by the individual vibration of each face plate concave portion and the face plate convex portion is reduced. , Each of these face plate recesses And the backing members individually attached to the center of the back surface of the convex portion of the face plate change their natural frequencies and cancel each other. As a result, the total vibration of the face plate portion, that is, Then, the generation of noise can be positively and effectively suppressed, and further, it has an excellent feature that it is relatively structurally simple and can be implemented easily and inexpensively.
