As a general exterior finish of buildings, composite panels made of tiles or plates made of natural materials such as stone and wood, and metal materials such as stainless steel, aluminum, copper, and titanium are used.In recent years, organic materials such as loess, etc. And ceramics are also used.

However, the exterior material using natural materials such as stone and wood is natural beauty, but the strength is weak and the weight is placed on the building due to the weight, while the tile or plate may fall due to vibration, and the installation cost is also high. have.

In addition, the external panel is also manufactured and used as a general steel sheet. Since the general steel sheet has not only a very low corrosion resistance but also a lack of exterior property, a separate powder coating and film are attached to secure corrosion resistance and exterior resistance. . Therefore, there is a problem in that a separate construction process is added to inhibit the work efficiency. Recently, there have been attempts to manufacture exterior panels using materials having excellent corrosion resistance and exterior properties, such as copper, stainless steel, and aluminum. However, the materials themselves are very expensive, so they are limited to high-end houses in terms of cost. It had a limit to use.

Accordingly, the inventors of the present invention have a sound absorbing and damping property of the building exterior panel itself, so that it is not necessary to add additional sound absorbing and damping subsidiary materials, and can greatly reduce the construction cost, and it is made of expensive materials such as copper having excellent surface finish and decorative taste. Bonding the surface plate made of a plate and the support plate made of a general steel plate with an adhesive resin significantly reduces the cost of the material while maintaining the excellent properties of the material exposed to the outside, and has a predetermined viscosity to provide excellent sound absorption and vibration damping properties. By the resin layer, it is possible to obtain external noise blocking and vibration suppression effects, and further, to add a heat insulation / sound insulation member, it has led to the development of a building exterior panel that can further increase the sound insulation, vibration damping, and heat insulation effects.

The present invention devised in order to solve the above-mentioned conventional problems is to increase the sound absorption and vibration damping by maintaining the adhesive resin layer of the bonded steel sheet constituting the exterior panel to have a predetermined viscosity, attenuated noise and vibration from the outside Its purpose is to provide architectural exterior panels.

On the other hand, the present invention to solve the problem that the manufacturing cost is significantly increased when using a relatively expensive single plate, such as copper, stainless steel, aluminum, etc., the surface plate material is exposed to the outside manufactured by an expensive material At the same time, the support plate material supporting the surface plate material inside is formed of relatively inexpensive steel plate, and the surface plate material and the support plate material are bonded by using the adhesive resin which is excellent in sound absorption and vibration damping, thereby greatly reducing the weight and manufacturing cost. In addition, the object of the present invention is to provide a building exterior panel that can enhance the decorative and surface treatment properties of the surface plate exposed to the outside.

In addition, the present invention is an exterior material formed by bonding two or more homogeneous or heterogeneous plate materials, and since the inherent characteristics of the material are maintained as compared to the composite metal, it is a special method for exterior drawing such as shape, shape, and surface treatment. Since it is not required, the purpose is to provide a building exterior material that is convenient for surface processing, light weight, prevents material damage, and is easy to install and replace.

In addition, it is possible to greatly reduce the transmission of vibration and noise to the wall through the building exterior panel, thereby creating a more comfortable and quiet indoor environment.

In order to achieve the above object, the present invention provides a building exterior panel installed directly on a wall or by an anchor after mounting an anchor, wherein the exterior panel includes a surface plate material, a support plate material for supporting the surface plate material, and the surface plate material and the support material. Disclosed is a laminated structural steel sheet comprising an adhesive resin layer disposed between the sheet material and bonding the surface plate material and the support plate material to each other, wherein the adhesive resin layer has a thickness of 0.02 to 0.1 mm.

Preferably, the exterior panel is bent to form an accommodation space therein, the accommodation space is further provided with a heat insulation / sound insulation member.

More preferably, the adhesive resin layer has a viscosity of 2500-4500 cps, and the surface plate member and the support plate member have a bending rigidity of 10.5-16.5 Nm.

Most preferably, the adhesive resin layer is 44 to 46% by weight of ethyl acetate, 40 to 42% by weight of vinyl acetate / acrylic copolymer, 8 to 10% by weight of isopropyl alcohol, 1 to 3% by weight of toluene, vinyl acetate 3 wt% or less and acetaldehyde 0.1 wt% or less.

Preferably, the surface plate material is any one selected from copper, stainless steel, aluminum, the support plate material is any one selected from galvanized steel sheet, stainless steel, aluminum, color steel sheet, cold rolled steel sheet and pickling steel sheet.

Hereinafter, with reference to the accompanying drawings will be described in detail the building exterior panel of the present invention.

1 is a perspective view of a building exterior panel according to an embodiment of the present invention. 2 and 3 is a cross-sectional view of the installation of the building exterior panel according to an embodiment of the present invention.

Referring to FIG. 1, the building exterior panel according to the present invention is a panel attached to a wall outer wall of a building, and the surface is formed in various designs to make the exterior of the building beautiful, and to block noise, absorb sound, and insulate effects. It is a kind of architectural exterior material that can be obtained. As shown in FIG. 1, the building exterior panel according to the present invention is disposed between the surface plate member 10a, the support plate member 10c for supporting the surface plate member, and the surface plate member and the support plate member. It consists of the adhesive resin layer 10b which mutually bonds a support plate material, The said adhesive resin layer consists of thickness of 0.02-0.1 mm.

As shown in FIG. 1, the exterior panel 10 is bent to form an accommodation space therein, and the accommodation space further includes a heat insulation / sound insulation member to further increase thermal insulation and noise blocking effects.

Referring to Figure 2, in installing the building facade panel according to the present invention directly on the wall, a plurality of exterior panels are continuously installed on the wall surface using bolts 22, etc., and finished with silicon 24 to be constructed. To complete. FIG. 3 is a cross-sectional view of a wall installed using anchors. First, anchors 30 are installed on a wall, and then a plurality of exterior panels are arranged in the anchors 30 to form bolts 32. It is fixed by, and finally finished with silicon 24 or the like to complete the construction.

Preferably, the surface plate (10a) is any one selected from copper, stainless, aluminum, the support plate (10c) is galvanized-steel (Stainless), stainless steel, aluminum, color steel sheet One of all types of steels was chosen, including Polyester Painted Steel Sheets, Cold Rolled Steel Sheets and Pickled and Oiled Steel Sheets. Here, galvanized steel sheets are galvanized steel sheets, electrolytic galvanized steel sheets, galvanized steel sheets, galvanized steel sheets, and galvalume. It should be interpreted as a broad concept including zinc aluminum alloy coated steel sheets.

The surface plate material 10a and the support plate material 10c of the building exterior panel 10 should have appropriate molding processability to be bent or pressed into a specific shape. In order to satisfy this, the bending stiffness of 10.5 to 16.5 Nm ( It is preferable to select and use a material having bending rigidity.

The bending stiffness is calculated using the Ross Kerwin Ungar (RKU) method represented by Equation 1 below.

Where B _c is the bending stiffness, υ is the Poisson's ratio, and t _c is the overall thickness.

In particular, when the bending stiffness is less than 10.5 Nm, there is a problem that it may be vulnerable to external impact after molding even with a small force, and when the bending stiffness exceeds 16.5 Nm, the bendability is lowered to properly shape the building exterior panel. There is a problem that cannot be molded.

The adhesive resin layer is disposed between the surface plate member and the support plate member, and serves to bond the surface plate member and the support plate member to each other, and is preferably formed to have a thickness of 0.02 to 0.1 mm. If the thickness is less than 0.02 mm there is a problem that the sound absorption is lowered, if it exceeds 0.1 mm there is a problem that the adhesive resin layer can not maintain a uniform viscosity in the thickness direction. The adhesive resin layer is disposed between the surface plate and the support plate to perform vibration damping, sound absorption, and heat insulation, thereby allowing the building exterior panel to have excellent vibration damping, sound absorption, and thermal insulation effects. In other words, the adhesive resin layer bonds the surface plate and the support plate and at the same time serves to attenuate the vibration and noise applied from the outside, and also serves as a heat insulator, thereby solving the noise and vibration problems, Increase the thermal insulation efficiency.

Adhesive resin used in the bonded steel sheet of the present invention is 44 to 46% by weight of ethyl acetate, 40 to 42% by weight of vinyl acetate / acrylic copolymer, 8 to 10% by weight of isopropyl alcohol, 1 to 3% by weight of toluene, vinyl Up to 3% by weight of acetate and up to 0.1% by weight of acetaldehyde. The composition and content as described above, the inventors have sound absorption and bonding properties by long-term repeated experiments, and at the same time can maintain a predetermined viscosity, so that the joined plate material is not separated from each other during the molding process.

Preferably, the adhesive resin used in the present invention has a viscosity of 2500-4500 cps. This means that when the viscosity is less than 2500 cps, the viscosity is so small that the bonded surface plate material is not firmly adhered to the support plate material, so that peeling occurs. If the viscosity is more than 4500 cps, the viscosity is too large, especially when molding the bonded steel sheet, some hardened adhesive resin layer is broken or the surface plate material is bent. Therefore, the adhesive resin used in the present invention not only has excellent molding processability when maintaining a predetermined viscosity, but also has an advantage of further increasing vibration damping, sound absorption, and heat insulation effects in order to maintain such viscosity.

Table 1 shows measured values of molding processability, peeling presence, and sound insulation effect of the bonded steel sheet according to the viscosity of the adhesive resin.

※ In molding processability, X means that in case of forming process such as bending, press work, drawing, etc., the adhesive resin leaks through the end face of the bonded steel sheet or the bonded steel sheets are separated from each other, so that a step occurs or the adhesive resin is broken so that it does not have proper adhesive strength. Indicates a case where part is found and ○ indicates a case where no one is found.

* With or without peeling, X represents a case where no peeling occurs at all, Δ represents a case where a part is found, and O cannot be found at all.

* When the noise of a single steel sheet is 1, the noise measured when replacing a bonded steel sheet having a predetermined viscosity is expressed as a relative value.

As can be seen from Table 1, when the viscosity of the adhesive resin is 2500 ~ 4500 cps, the moldability is excellent, the peeling does not occur, and the sound insulation effect was also excellent compared to a single steel sheet.

On the other hand, the present inventors obtained the frequency response function curve by hanging the exterior panel sample and exciting the hammer with impact hammer to test the vibration damping characteristics of the building exterior panel, and from the frequency response function curve, 1, 2 or 3rd inherent Frequency and loss coefficients at each natural frequency were obtained by half width method. In order to reduce the measurement error during the test, the measured values were obtained through three tests for each sample. Samples used were single STS steel sheet, STS bonded steel sheet, single Cu steel sheet, Cu bonded steel sheet, single Al steel sheet, Al bonded steel sheet, and the thickness of all samples was 0.8 mm.

As can be seen in Table 2, the building exterior panel according to the present invention showed an excellent vibration damping performance, especially in the medium and high frequency range, compared to the steel plate of a single material. Thus, shocks that may be generated from the outside are shock-absorbed by the building exterior panel itself, so that vibrations are not transmitted along the entire wall, thereby attenuating vibration and noise, and further, the panel itself is gradually peeled off from the wall by vibration. It can also solve the problem.

In addition, the present inventors measured the thermal conductivity and thermal diffusivity of the single steel sheet and the laminated steel sheet, respectively, in particular, the thermal conductivity and thermal diffusivity of the laminated steel sheet used as the exterior panel is much smaller than the single steel sheet, as a result of the conventional single steel sheet By manufacturing an exterior panel using a bonded steel sheet having a smaller thermal conductivity, it is possible to increase the insulation effect between the walls.

That is, as can be seen in Table 3, Cr bonded steel sheet, Cu bonded steel sheet, and STS bonded steel sheet are significantly smaller in terms of thermal diffusivity and thermal conductivity compared with the material composed of single steel sheet, respectively, to increase the insulation effect between walls. do.

As described above, the above-described embodiments are described with reference to the most preferred examples of the present invention, but are not limited to the above embodiments, and it will be apparent to those skilled in the art that various modifications can be made without departing from the technical spirit of the present invention. .

According to this invention, it has the following effects.

First, by maintaining the adhesive resin layer of the bonded steel sheet constituting the exterior panel to have a predetermined viscosity to increase the sound absorption and vibration damping, and greatly attenuate the transmission of noise and vibration from the outside to the wall for a more comfortable and quiet indoor environment Can be formulated.

Second, in the case of using a single expensive plate, such as copper, stainless steel, aluminum, etc., which is relatively expensive in the past, in order to solve the problem that the manufacturing cost increases significantly, the surface plate that is exposed to the outside is manufactured with an expensive material The support plate material supporting the surface plate material inside is formed of relatively inexpensive steel plate, and the surface plate material and the support plate material are bonded by using the adhesive resin which has excellent sound absorption and vibration damping property, which greatly reduces the weight and manufacturing cost and at the same time It is possible to enhance the decorative and surface treatment properties of the surface plate exposed.

Third, it is an exterior material composed of two or more homogeneous or heterogeneous plates bonded together, and since the inherent characteristics of the material are maintained as compared to the composite metal, no special method is required for exterior production such as shape, shape, and surface treatment. It is convenient for surface processing, light in weight, and prevents damage to materials and is easy to install and replace.

Fourth, by manufacturing a building exterior panel using a laminated steel sheet having a lower thermal conductivity and thermal diffusivity than a single steel sheet, it is possible to provide a building exterior panel that can significantly increase the heat insulation and insulation effect compared to conventional exterior panels.
