The present invention relates to a roof panel using a laminated steel sheet, and more specifically, the roof panel itself has sound absorption, vibration damping, and heat insulating properties, and thus, there is no need to introduce a separate sound absorbing, damping, and insulating structure, thereby significantly reducing construction costs. By joining steel plate to expensive non-ferrous metal plate, it can be used as a roofing material, which can greatly reduce the cost of the material. Furthermore, it has a predetermined viscosity, which is artificially or naturally externally made by an adhesive resin layer with excellent sound absorption, vibration damping, and heat insulation. The present invention relates to a roof panel that can effectively suppress vibrations and noises applied from the panel and at the same time obtain thermal insulation effects.

In general, the basic material of the roofing material, which is a kind of building exterior material, is usually constructed of synthetic resin, clay material, iron plate, nonferrous metal, etc. However, synthetic resin, clay material has a disadvantage in that it is likely to adversely affect the environment due to difficulty of recycling. In particular, in the case of clay materials, there is a great difficulty in managing construction materials, such as easily deformed and damaged products in transportation and space and time. In addition, the roofing material of the iron plate and non-ferrous metal can solve the above-described problems of the synthetic resin and clay material, but the roofing material of the general iron plate is easily corroded to the external environment such as rainwater, pollutants, etc. It is used only for roofs and low cost buildings.

Recently, non-ferrous metal roofing materials such as copper, stainless steel, aluminum, and other imported non-ferrous metals have the advantage of eliminating the problems of environmental, material management, decorative beauty, and corrosion resistance, which are problems of the synthetic resin, clay, and steel sheet. It is currently used most as a roofing material. However, non-ferrous metals are so expensive that they act as a major cause of rising construction costs. Especially when manufactured in a single plate, noise and vibration are transmitted through a single steel sheet during thunderstorms when human or natural factors such as rainwater or hail fall. There has been a problem that results in damaging the comfortable and stable indoor living environment.

As a result, when manufacturing a roofing material with a single plate, additional insulation, sound absorbing material, and vibration damping material are additionally installed in the roof structure to obtain sound absorption, vibration damping, and heat insulation effect. There is a problem that the increase in the material cost, and furthermore, the construction process is added to reduce the work efficiency to extend the air as well as to increase the construction cost.

Therefore, the present inventors can significantly reduce the construction cost because the roofing panel itself has sound absorption, vibration damping, and heat insulation, and does not need to install additional sound absorption, vibration damping, and heat insulation members, and a support plate made of a non-ferrous metal surface plate and a general steel plate. Can be significantly reduced the cost of the material, and furthermore, the adhesive resin layer having a predetermined viscosity, excellent sound absorption, vibration damping, and heat insulation, can provide noise prevention and vibration suppression effect. Since the sheets joined to each other during the molding process are not spaced apart from each other, it has led to the development of roof panels that can produce panels of various shapes.

The present invention devised to solve the conventional problems as described above is to maintain the adhesive resin layer of the roofing panel to a predetermined viscosity, the adhesive resin layer having a viscosity to increase the sound absorption, vibration damping and heat insulation, transfer from the outside It can attenuate noises and vibrations and obtain a warming effect, creating a pleasant and comfortable living environment, and furthermore, a roofing material that can secure excellent molding processability by not breaking the adhesive resin layer having a predetermined viscosity during molding process. The purpose is to provide a panel.

In addition, the present invention in order to solve the problem that the manufacturing cost is significantly increased when using a single steel plate, such as conventional relatively expensive copper, stainless steel, the surface plate exposed to the outside is made of non-ferrous metal to the same texture and appearance as before It is an object of the present invention to provide a roof panel that can maintain the surface plate material while supporting the surface plate material at the same time, by making the steel plate relatively inexpensive, thereby greatly reducing the material cost.

On the other hand, the present invention does not need to install the sound-absorbing and heat insulating material that was installed separately separately, so that the roofing panel itself has a sound absorption, vibration damping, and heat insulation, and as a result, the work efficiency is high, which shortens the air, thereby greatly reducing the construction cost. The purpose is to provide a roof panel.

In order to achieve the above object, the present invention provides a roof panel that can be interconnected to assemble a roof, wherein the roof panel is disposed between a surface plate, a support plate for supporting the surface plate, and the surface plate and the support plate. The present invention relates to a roof panel comprising an adhesive resin layer for bonding the surface plate material and the support plate material together.

Preferably, the roof panel overlaps the ends of panels adjacent to each other, forms at least one fastening hole through the overlapped portion, and connects adjacent panels by fastening fastening members such as bolts.

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

According to another embodiment of the present invention, an upper roof panel which is continuously connected to each other by overlapping the end of the panel adjacent to each other and fastening the fastening member such as bolt to the fastening hole formed in the overlapping portion; A lower roof panel having a fastening hole formed at a position corresponding to the fastening hole formed at an overlapping portion of the upper roof panel, and arranged to face the upper roof panel; And a spacer disposed between the upper roof panel and the lower roof panel to maintain a gap between the upper roof panel and the lower roof panel, wherein the upper and lower roof panels are surface plates and support plates for supporting the surface plates. And an adhesive resin layer disposed between the surface plate member and the support plate member to bond the surface plate member and the support plate member to each other.

Preferably, the insulation sound absorbing agent is further provided in a space formed between the upper roof panel and the lower roof panel and the spacer.

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

1 is a cross-sectional view of an installation of a roof panel according to an embodiment of the present invention, Figure 2 is a perspective view showing an example of manufacturing a roof using a roof panel according to an embodiment of the present invention.

1 and 2, the roofing panel according to the present invention overlaps the ends of the panels adjacent to each other, forms at least one fastening hole through the overlapping portion, and fastens the fastening member 12 such as a bolt. Connect adjacent panels in series.

As shown in FIG. 1, the roofing panel is disposed between the surface plate 10a, the support plate 10c for supporting the surface plate 10a, and the surface plate 10a and the support plate 10c. And an adhesive resin layer 10b for bonding the surface plate 10a and the support plate 10c together.

The surface plate material 10a is any one selected from copper, stainless steel, aluminum, color steel sheet, cold rolled steel sheet, pickling steel sheet, titanium zinc plate, and zinc plate. The surface plate 10a is preferably made of a material having corrosion resistance to prevent rust because it is always exposed to rainwater and pollutants due to the characteristics of the roofing material.

On the other hand, the support plate (10c) is galvanized steel (Galvanized-Steel), stainless steel (Stainless), color steel (Polyester Painted Steel Sheets), cold rolled steel (Cold Rolled Steel Sheets), pickled steel sheets (Pickled and Oiled Steel Sheets) One of all types of steels, including zinc, zinc, and titanium zinc plates. 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 and support plate constituting the roof panel should have excellent molding processability in order to mold the roof panel into various shapes, and in order to satisfy such molding processability, materials having bending rigidity of 10.5 to 16.5 Nm may be used. Preference is given to using.

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 bent with a small force, and thus may be vulnerable to external impact after molding. When the bending stiffness is more than 16.5 Nm, the formability decreases, and thus the roofing panel may have various shapes. There is a problem that cannot be molded.

The adhesive resin layer 10b is disposed between the surface plate member 10a and the support plate member 10c, and serves to bond the surface plate member and the support plate member to each other, and preferably has a thickness of 0.02 to 0.1 mm. Form. The adhesive resin layer is disposed between the surface plate and the support plate to perform vibration damping, sound absorption, and heat insulation, so that the roofing panel itself has excellent vibration damping to sound absorption and thermal insulation. That is, the adhesive resin layer bonds the surface plate material and the support plate material, and at the same time, serves to attenuate vibration and noise applied from the outside, and also serves as a heat insulating material.

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 and heat insulating properties by repeated experiments for a long time, 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 sound insulation effect is shown by comparing the performance of sound insulation by the bonded steel sheet.

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.

In order to test the vibration damping characteristics of the roof panel, the present inventors obtained a frequency response function curve by suspending the roof panel sample and exciting the hammer with impact hammer, and obtained the first, second or third natural frequency from the frequency response function curve. The loss coefficients at and the natural frequencies were obtained by the 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 roof 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.

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 roofing panel is much smaller than the single steel sheet, and as a result, the conventional single steel sheet By manufacturing a roof panel using a bonded steel sheet having a smaller thermal conductivity, it is possible to increase the insulation effect of the roof.

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 to materials made of single steel sheets, respectively, to insulate the insulation and heat insulation effect of roofing materials. Increased.

Fastening upper roof panel is connected continuously; A lower roof panel having a fastening hole formed at a position corresponding to the fastening hole formed at an overlapping portion of the upper roof panel, and arranged to face the upper roof panel; And a spacer installed between the upper roof panel and the lower roof panel to maintain a gap between the upper roof panel and the lower roof panel.

Referring to FIG. 1, the upper roofing panel 10 and the lower roofing panel 20 are arranged in a double arrangement to face each other, and the upper roofing panel is continuously connected to form a roofing material. The spacer 30 is fixed to the panel by the fastening member 32 in order to maintain a constant gap between the roofing panel, the heat insulating sound absorbing material 40 in the space formed between the upper roofing panel and the lower roofing panel and the spacer It can also be comprised by providing.

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 roofing panel to a predetermined viscosity, the adhesive resin layer having a viscosity increases the sound absorption, vibration damping and heat insulation, can attenuate the noise and vibration transmitted from the outside, and can even obtain a warming effect Therefore, it is possible to create a comfortable and comfortable living environment, and furthermore, it is possible to secure an excellent molding processability because the adhesive resin layer having a predetermined viscosity during the molding process is not broken.

Second, when using a single steel sheet such as copper, stainless steel, etc., which is relatively expensive in the related art, in order to solve a problem in which manufacturing cost increases significantly, the surface plate exposed to the outside is made of non-ferrous metal to maintain the same texture and appearance as before. At the same time, the support plate material for supporting the surface plate material therein can be made of a relatively inexpensive steel plate, thereby significantly reducing the material cost.

Third, since the roofing panel itself has a sound absorption, vibration damping, and heat insulation function, there is no need to construct a sound absorbing and heat insulating material, which has been separately installed in the past, and as a result, the work efficiency is high, which shortens the air, thereby significantly reducing the construction cost.
