Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a metal face plate for construction, and more specifically,
Improvement of architectural metal face plates used for horizontal and vertical roof plates for metal roof structures in buildings, or for exterior plates and wall panels for metal exterior structures, in particular, to provide at least soundproofing and sound insulation properties. This invention relates to a metal face plate for construction that has been improved as described above.

[Conventional technology]

Conventionally, in this type of architectural metal surface structure, metal surface plates such as horizontal roofing panels, vertical roofing panels, exterior panels, and wall panels used for nine-sided structural members exposed on the surface of the surface structure. In general, as a method for improving the soundproofing properties, noise insulation properties, etc. of a metal face plate member having a face plate portion with a suitable surface area that serves as at least the main surface, prior to tensioning the metal face plate member, Sound absorbing and sound insulating materials made of separate board-shaped members are laid over the entire surface of the base, and these sound absorbing and sound insulating materials serve their respective roles, that is, sound absorption and sound insulation. This method has been widely adopted.

[Problem to be solved by the invention]

However, with this indirect method of simply bringing a sound absorbing material or a sound insulating material into contact with the back surface of the metal face plate member, the metal face plate member exposed on the surface of the surface structure cannot be used. If an external force is applied to the face plate and it vibrates directly, causing the metal face plate itself to become a noise source, the idea is to absorb or insulate the noise, assuming that the noise itself is already occurring. However, since it does not prevent the generation of noise itself, it is only a second-best measure, and cannot necessarily be said to be an active soundproofing or soundproofing measure.

On the other hand, in order to prevent the vibration itself, in other words, the generation of noise itself, from flowing directly to the metal face plate member,
A metal face plate member made of a metal material with a relatively high areal density, and a sound-absorbing backing member made of a material with a relatively low areal density, such as foamed polyurethane foam, on the entire back surface including the face plate part. There are other methods, such as attaching a back-up material under pressure to the back side of the face plate part of the metal face plate member.Furthermore, as a relatively new attempt, It is also being considered to form the material itself from a resin-laminated steel plate, a so-called vibration-damping steel plate.

However, the method of attaching a sound-absorbing backing material such as foamed polyurethane foam to the entire back surface of the metal face plate member has the advantage of ease of handling during the manufacturing process, as well as soundproofing and sound insulation. In terms of countermeasures, extremely insufficient performance can be achieved, and even if high areal density rubber or resin-based materials are used for the backing member, the thickness of the molded plate will increase unnecessarily. , the conventionally used general-purpose production line cannot be used for S, and an extremely limited dedicated production line that can only be used for the production of S itself is required, and as a result, the metal face plate manufactured There is a disadvantage that the damping steel plate itself is very expensive, and this is exactly the same when using a damping steel plate.

Also, when compared to the former method, the method for applying the back-up material along the back surface of the face plate portion of the metal face plate member is different.

Although this S is more effective, in order to obtain a good soundproofing effect, it is necessary to actively press the backup material against the face plate, and it is necessary to use another mechanism for pressure contact. In addition to various problems that needed to be resolved, such as the accuracy of the press-contact surfaces, the overall structure was also likely to become complicated and extremely expensive.

Furthermore, when the face plate part of a metal face plate member is composed of a plurality of divided face plate parts that are not flat in plan,
In other words, the face plate part forming the main surface of the metal face plate member is divided into a plurality of parts by intermediate bent edges in order to change the surface shape or to reinforce the overall strength. In such a case, for example, if these face plate parts each have a correspondingly different surface area, it may be impossible to prevent the combined noise caused by each vibration. Ta.

Therefore, in view of the above-mentioned conventional problems, the object of the present invention is to address the parts of the metal face plate member that are most likely to vibrate and generate noise.

That is, effective and practical noise prevention measures were taken for each of the face plate sections, each of which has a suitable surface area and is divided into a plurality of sections. The object of the present invention is to provide a metal face plate for construction of this kind.

[Means to solve the problem]

In order to achieve the above object, the architectural metal face plate according to the present invention has each face plate part having a suitable surface area as a main surface and divided into a plurality of parts by intermediate bent edges,
In a metal face plate member in which a mounting engagement part for attachment to the base material side is molded on at least each side edge in the width direction that is common through each face plate part, the surface of the material of the metal face plate member is formed. A plate-like or sheet-like backing member made of a material with an areal density different from the density is provided, and between each engaging side bent edge forming each of the mounting engagement parts and the intermediate bent edge. The width of each face plate part in lal and Jl respectively.
When bl, widths λa2 (ILal>1 a2) and R, which are shorter than the widths jlal and ubl, are placed at predetermined positions in the width direction on the back surface of each of these face plate parts in the length direction.
b2 (ILbl>1 b2), and is characterized in that backing members of arbitrary lengths are individually attached.

[For production]

That is, in this invention, each face plate part has a suitable surface area as a main surface and is divided into a plurality of parts by intermediate bent edges, and at least each side edge in the width direction common through each face plate part, For installation on the base material side, a plate-shaped backing member made of a material with a surface density different from that of the metal face plate member is attached to the metal face plate member, each of which has a molded attachment engagement part for fastening. When the widths of each face plate portion between each engagement side bent edge and intermediate bent edge forming each mounting engagement portion are respectively set as la1 and lb1, these A width n a2 shorter than the widths lLa1 and 1Lbl is placed at a predetermined position in the width direction on the back surface of each face plate portion in the length direction.
(42at> 11 a2) and lb2 (JZbl
) 4b2) Since backing members of arbitrary lengths were attached separately to each other, the mass at each part of the surface, which was balanced only by the metal material of each face plate itself, was changed to the corresponding one. The attachment of each backing member to the back surface of the face plate portion causes them to be unbalanced.

In other words, since the natural frequencies of each part of the same surface are no longer uniform, each face plate part itself has a balanced mass on each part of its surface, so the entire surface is integrated. In addition, the natural vibrations that were occurring in series, and by extension the initial vibrations of each face plate part, directly cancel each other out due to the difference in natural frequency or imbalance between each part of the surface. As a result, the vibration of each face plate part, and by extension the overall vibration of each face plate part, in other words, the generation of noise contained by the metal face plate member itself can be actively and effectively suppressed. It can be suppressed.

(Example) Examples of the architectural metal face plate according to the present invention will be described below.
This will be explained in detail with reference to FIGS. 1 to 3.

FIG. 1 is a partially sectional perspective view showing the general structure of a horizontal roof plate member in a first embodiment in which the architectural metal face plate of the present invention is applied to a horizontal roof structure.

That is, in the configuration of the first embodiment shown in FIG.
Symbol (1) indicates a horizontal roofing plate member as a metal face plate member, and this horizontal roofing plate member (1) is formed by continuously forming, for example, a long metal thin steel plate by roll forming or the like. By doing so, each of the face plate parts (2a) and (lb) having the required appropriate surface area at the center in the width direction and divided into a plurality of parts by the intermediate bent edge (3) are left. An eave side molded part (4) is provided on at least one common connection side edge side in the width direction through each face plate part (2a), (lb), and a line side molded part (4) is provided on the other connection side edge side.
5) are each formed into a predetermined cross-sectional shape,
It is cut into a predetermined standard unit length in the length direction, and the two cut ends are used as connecting edges (6) and (7). For each of the molded parts (4) and (5) on the eave side and line side, one molded part placed adjacent to the eave side and the line side is connected to the other molded part. After they are engaged, they are fastened to the roof base using a specified hanging member, etc., and even if they are at both the corresponding connecting edges (6) and (7) in the length direction, they can be discarded as appropriate. (not shown), etc., so that the metal surface structure, in this case the roof surface, can be raised as desired.

The horizontal roofing board member (1) in this N has molded parts (4) on the eave side and line side formed on both side edge sides thereof.
Regarding (5), since this is a relatively narrow form, there is no room for sufficient strength to be imparted within a limited range to allow free movement, but each of these molded parts (4) A width that is relatively likely to cause free vibration between each of the folded edges (8) and (9) corresponding to the forming start ends of (5) and the intermediate folded edge (3). Face plate portions (2a) and (lb) of lLa1 and ILbl
) are formed respectively, and these face plate parts (2a
), (lb), based on the size of the effective surface area set for each part, in conjunction with the areal density, plate thickness, toughness, and form of forming of the thin metal sheet used, etc. Each of these face plate portions (2a) and (lb) is given a natural frequency (Aa) and (Ab), respectively, and a predetermined natural frequency (A) is given to the whole of these face plate portions (2a) and (lb).

Further, (11) is a backing member formed of a different material having an areal density different from that of the metal material at each face plate portion (2a), (lb) of the horizontal roofing board member (1). The backing member (11) has, for example, a thickness appropriate to the material used, and as will be described later, the back side of each of the face plate parts (2a) and (lb) has a thickness corresponding to that of the material used. In the pasted state, each face plate part (2a) at the same pasted part
, (lb) of a material that can sufficiently change the natural frequencies (Aa) and (Ab) 1 For example, the face plate part (2a)
, using a rubber plate, rubber sheet, vinyl chloride plate, vinyl chloride sheet, etc., which has a specific natural frequency (B) different from the natural frequency (Aa) and (Ab) of (lb), and its shape, As for the size, each face plate part (2
a).

It is preferable that the width be sufficiently thicker and narrower than the thickness of (lb) and set to the required length, including the case of this embodiment as well as the cases of other embodiments described later. In this case, a rubber sheet with a natural frequency (B) is used as the material, and in particular, each of the face plate parts (2a) and (lb)
The width 11 a is shorter than the width la1 and ff1bl of
2 (ffi al> IL a2) and 1b2 (
JZbl>ub2) each backing material (12a) and (1
Prepare lb).

Therefore, in the configuration of the first embodiment, as shown in FIG. Each molded portion (4) is placed at a predetermined position 2 in the width direction according to its width ual, for example, at a middle portion in the width direction.

(5) Over the entire length in the length direction parallel to the direction, it has a natural frequency (B) and has a width n a2 (ILal> fl
Similarly, the backing material (12a) used as a2) is placed on the back surface of the face plate part (lb) having the natural frequency (Ab), and at a predetermined position 1 in the width direction according to its width xbi, for example, in the width direction. In the middle part, over the entire length in the longitudinal direction parallel to the direction of each molded part (4) and (5), the natural frequency (B)
A backing material (1 lb) with a width of jZb2 (JZbl>ub2) was pasted in series so that it would not easily fall off, and each of these and, by extension,
It is an integrated whole.

Therefore, in the first embodiment configured in this way,
Width lal and IL for each horizontal roofing board member <1)
Each backing material (12a) when looking through the entire surface portion of each face plate portion (2a) and (lb) designated as bl.

Before the attachment of (+lb), the solid W frequency (Aa), (
Ab), and furthermore, the width 1a2 (j!a) which had a natural frequency (A) in the series part has a natural frequency (B) at a predetermined position on the back side of each face plate part (2a), (lb).
By integrally attaching each of the backing materials (12a) and (1lb) with l>la2) and l1b2 (jlbl>n b2), the natural frequency of only the attached part is the same as that of both of them. Natural frequency (A), (
B) changes to the natural frequency (A, 13), which is a composite of Each backing material (12a), (12a), (12a), (12a), (12a), (12a), (12a), (12a), (12a), (12a), (12a), (12a), (12a), (12a), (12a), (1b), when external pressure of raindrops, wind friction, etc. Since the natural frequencies (A) and (A, B) of the part to which (1lb) is not attached and the part to which it is attached are different from each other, each part of this surface The mass of the face plates (2a) and (lb) is now unbalanced, and the natural vibration of the frequency (A), which conventionally occurred in series on each surface side of each face plate part (2a) and (lb), is now generated on each part of these surfaces. Each natural frequency (A) between each other
, (A, B) are directly canceled out, and in this X, each face plate portion (2a).

(lb), and by extension, the total vibration of both of these parts, in other words, the generation of noise is actively and effectively suppressed.

In addition, the natural frequencies (Aa) and (Ab) in each of the face plate parts (2a) and (lb) and each backing material (12a) are
), (1lb) and the natural frequency (B), in addition to the above-mentioned difference in areal density between the two, selection can also be made based on the difference in specific gravity between the two. Similar actions and effects can be achieved.

In addition, the width j2a of each of the face plate portions (2a) and (lb)
Each backing material (12a), (1

fLb2 may be set to approximately yH.

That is, according to the inventor's experiments, each face plate portion (2a
), (lb) width 1 at, each backing material (12a), (1lb) width 1a2 (n

) is set to about a high percentage, the backing material is applied to the entire back surface of the face plate to reduce the noise level that would occur when these backing materials (12a) and (1lb) were not attached. It was confirmed that if the reduction rate of the noise level when affixed is 10 frames, a value of about 7596 can be obtained. In particular, the reduction in noise in this case was more noticeable in the high frequency range, which is extremely annoying to people living inside buildings.

In addition, even if the above-mentioned width dimension ratio relationship is set to approximately 2%, the reduction in the noise level is approximately 60t, and as shown in the figure, the noise level decreases by approximately 60t, and as shown in FIG. , each backing material with different areal density (+2a)
, (1 lb) was fully demonstrated to be extremely effective or unique in terms of noise suppression.

On the other hand, as for the attachment position of each backing material (12a), (1lb) to the back surface of each face plate part (2a), (1b), as can be seen in the configuration of this first embodiment, vibration generation The same face plate portions (2a), (l
Although it is effective to set the vibration center in b), that is, the middle part in the width direction, depending on the given cross-sectional shape, the vibration center is not necessarily the center of each face plate (2a), (l
b) may not be located at the center in the width direction, so the vibration center should be selected as much as possible, or the vibration waves propagated by the vibration generated in each face plate part (2a) and (lb) should be It is preferable to select and paste the part corresponding to the node.

Furthermore, the length of adhesion of each of the backing materials (12a) and (1lb) to the back surface of each of the face plate parts (2a) and (1b) is X, but as can be seen in the configuration of this first embodiment, It may be pasted over the entire length of each face plate part (2a), (lb) of this horizontal roofing board member (1), and with this configuration, no major modifications are made to the roll forming machine when manufacturing it. , the existing general-purpose manufacturing line can be used as is.
It is advantageous to use it.

In the case of the configuration of this first embodiment, each face plate part (2a) is
, each backing material (12a) affixed to the back side of (lb)
), (tzb) materials can be significantly reduced.

Next, in the case of the configuration of this first embodiment, the horizontal roof plate member (
1) are successively connected at each connection end edge (6), (7) in the length direction via appropriate tank plates (not shown). As in the embodiment configuration, each backing material (12a), (1lb) at both connecting edges (6), (7) is partially missing, in other words, each backing material (12a), (1lb) at both connecting edges (6), (7) is Backing material (12a).

(1lb), each face plate part (2a), (l
By setting the length close to each of the connecting edges (6) and (7) instead of the full length of b), the work of raising the roof of the horizontal roofing board member (1) can be made easier.

Furthermore, as in the third embodiment configuration shown in FIG. 3, the horizontal roofing plate member (1) is provided with a synthetic resin laminate layer (22) on the surface of the steel sheet material to prevent vibrations. In other words, when using a resin-laminated steel plate with noise prevention measures, so-called excavation steel plate (21), each face plate part (2a), (lb) individually,
In addition, it is effective because the overall vibration can be suppressed even more effectively.

In addition, in each of the embodiments described above, the case was described where it was applied to a horizontal roof plate for a horizontal roof structure as a metal face plate for construction, but it can also be applied to a vertical roof plate for a vertical roof structure or for an exterior structure. It can be applied in exactly the same way to exterior panels and wall panels, etc., and is particularly applicable to metal face plate members in which the individual face plate parts are relatively wide and the intermediate bent edges are not supported on the back side. When the - layer, the effect is remarkable.

〔Effect of the invention〕

As detailed above, according to the present invention, it is used for horizontal roofing boards and vertical roofing boards for roof structures of buildings, or for exterior boards and wall panels for exterior structures, and is used as a main surface. Each face plate part has a suitable surface area and is divided into a plurality of parts by intermediate bent edges, and at least each side edge in the width direction that is common through each face plate part is attached to the base material side for fixing. In the metal face plate member in which the engaging portions are individually formed, a plate-shaped backing member made of a material with a different surface density from that of the metal face plate member is provided, and each mounting engagement portion is formed. The width of each face plate portion between each engaging side bent edge and the intermediate bent edge is ual.
and fl, bl, a width 11 a2 (41al> J
Z a2) and ILb2 (Jl! bl> u b
In 2), backing members of arbitrary lengths were attached separately to each other, so if each of these face plate parts was alone, the mass at each part of the surface that was balanced by itself would be Due to the attachment of each backing member, each part becomes unbalanced and the natural frequency of each part of the surface becomes uneven, so if each face plate itself is used alone, the mass of each part of the surface will be in a balanced state. Due to the fact that the natural vibrations of the entire surface were occurring as a whole and in series, the initial vibration of each face plate itself was caused by the difference in natural frequency between each part of these surfaces. , or directly cancel each other out due to the imbalance, and as a result, each of the face plate parts, and by extension, these parts actively and effectively reduce the overall vibration, or in other words, the generation of noise. It can be suppressed.

In addition, in this configuration in which each backing member is attached to the back surface of each face plate portion, that is, in a configuration in which each backing member is partially attached to each required part, it is difficult to use the conventional method. , through the entire back side of each face plate section, back up material,
This is completely different from methods such as adding a layer of material such as a urethane foam layer to the back of the base itself, such as a cushioning material. , because the material consumption of intervening members on the base side is small, it is possible to simplify the individual and overall structures, and combined with the ease of manufacturing, it helps reduce the overall cost. It has the following.
