If the longitudinal length (L in FIG. 3) of the coupling panel 2000 is less than 0,1 times the longitudinal length (W in FIG. 3) of the panel assembly 1000, the structural strength of the connection part of the panel assembly is improved Even if a fire occurs inside the building due to the failure to close the gap well so that there is no empty space in the connection part, the fire spreads between the connection parts between the panel assemblies, and deformation such as the panel assembly is twisted and opened, and the roof structure of the building occurs. There may be a problem that the fire-resistance function is lowered.

In addition, if the longitudinal length (L in FIG. 3) of the coupling panel 2000 exceeds 0, 4 times the longitudinal length (W in FIG. 3) of the panel assembly 1000, the lower part of the coupling panel is the second Since the first panel is directly contact-coupled and the upper part is directly contact-coupled with the second panel, the first panel and the second panel are connected through the coupling panel 2000 .

Therefore, as the cold air of the second panel installed outside due to the strong cold is conducted to the first panel through the coupling panel 2000, condensation is generated on the roof structure of the building as a whole, which impairs a pleasant environment inside the building and prevents condensation. Accordingly, there may be problems of increasing the maintenance cost of the building and increasing harmful bacteria such as mold.

Although not necessarily limited thereto, the longitudinal length (L in FIG. 3) of the coupling panel 2000 is formed to be 0.1 times or more to 0.2 times or less of the longitudinal length (W in FIG. 3) of the panel assembly 1000. Most preferred. If it is formed within the above-mentioned range, the above-described problem can be further prevented.

In addition, in the roof structure (1) coupling panel 2000 of the building according to an embodiment of the present invention, the longitudinal length (L in FIG. 3) of the coupling panel 2000 is the first panel of the pre-installed panel assembly 2 (1100) and the core portion 1300 and the second panel 1200 in the state installed on one side of the coupling panel 2000 in the vertical direction (H in Fig. 3) to be formed to be at least 0,3 times and 0.5 times or less can

If the longitudinal length (L in FIG. 3) of the coupling panel 2000 is less than 0, 3 times the vertical length (H in FIG. 3) of the coupling panel 200, the structural strength of the connection part of the panel assembly is improved Even if a fire occurs inside the building due to the failure to close the gap well so that there is no empty space in the connection part, the fire spreads between the connection parts of the panel assembly, and deformation such as the panel assembly is twisted and opened, and the roof of the building occurs. There may be a problem that the fire resistance function of the structure is lowered.

In addition, if the longitudinal length (L in FIG. 3) of the coupling panel 2000 exceeds 0.5 times the vertical length (H in FIG. 3) of the coupling panel 2000, the lower part of the coupling panel is the second Since the first panel is directly contact-coupled with the upper part and the upper part is directly contact-coupled with the second panel, the first panel and the second panel are connected through the coupling panel 2000, so the second panel is installed outside due to strong cold. As the cold air of the air conducts to the first panel through the bonding panel, condensation occurs on the roof structure of the building as a whole, which impairs a pleasant environment inside the building, increases the maintenance cost of the building due to the condensation, and increases harmful bacteria such as mold This can happen.

The first panel 1100 , the second panel 1200 , and/or the bonding panel 2000 of the present invention may exhibit an anti-contamination effect by forming a coating layer using a coating composition having an excellent anti-contamination effect.

The coating composition is more specifically inorganic nanoparticles; cillin compounds; Surfactants; bookbinder; dispersant; and solvents.

The average diameter of the inorganic nanoparticles is 3 to 5 μm. As the inorganic powder having a small average diameter within the above range is used, even if the coating layer is formed, the touch may not be impaired.

The inorganic nanoparticles are selected from the group consisting of barium titanate, silica (SiO2), titanate (TiO2), and mixtures thereof, and preferably barium titanate, but is not limited thereto.

Preferably, the silane compound is a compound represented by the following formula (1):

[Formula 1]

here,

n is an integer from 1 to 100;

The silane compound may include a plurality of -OCF3 substituents, and may increase the antifouling effect by forming a fluorine film in the coating layer by the -OCF3 substituents.

In addition, since it contains an alkylene group having 1 to 100 carbon atoms as a linker, -OCF3 substituents can be arranged at a certain distance on both sides around the ester group, thereby preventing the problem of interference with inorganic nanoparticles in the coating layer Accordingly, the antifouling effect can be further increased.

Preferably, the linker is an alkylene group having 5 to 10 carbon atoms, that is, n is an integer of 5 to 10, and when forming a coating layer within the above range, a fluorine film that can maximize the antifouling effect within the thickness range of the coating layer formation is possible. This may cause a problem that the antifouling effect is inhibited due to the interference effect between the inorganic nanoparticles and the -OCF3 substituent when n is less than 5, and when n exceeds 10, the distance between the inorganic nanoparticles and the fluorine film in the coating layer is Although it is possible to prevent the occurrence of an interference effect by moving away from it, there is a problem in that the antifouling effect due to the combination of the fluorine film and the inorganic nanoparticles is lowered.

The surfactant is a betaine-based surfactant, and more specifically, an alkylbetaine-based, amidebetaine-based, sulfobetaine-based, hydroxysulfobetaine-based, amidosulfobetaine-based and phosphobetaine-based, imidazolinium betaine-based surfactants. It may be selected from the group consisting of, but is not limited to the above examples.

The binder is selected from the group consisting of acrylic binders, urethane-based binders, silicone-based binders, and mixtures thereof, more specifically silicone-based binders, and more specifically polydimethylsiloxane, polyhydrosiloxane, and mixtures thereof. However, it is not limited to the above example.

The dispersant may use a known component employed in the art as a dispersant of the carbon-based filler. More specifically, polyester-based dispersing agent, polyphenylene ether-based dispersing agent, polyolefin-based dispersing agent, acrylonitrile-butadiene-styrene copolymer dispersing agent, polyarylate-based dispersing agent, polyamide-based dispersing agent, polyamideimide-based dispersing agent, polyarylsulfone-based dispersing agent dispersing agent, polyetherimide-based dispersing agent, polyethersulfone-based dispersing agent, polyphenylene sulfide-based dispersing agent, polyimide-based dispersing agent; Polyether ketone dispersant, polybenzoxazole dispersant, polyoxadiazole dispersant, polybenzothiazole dispersant, polybenzimidazole dispersant, polypyridine dispersant, polytriazole dispersant, polypyrrolidine dispersant, polypyrrolidine dispersant It may be selected from the group consisting of dispersants, polysulfone-based dispersants, polyurea-based dispersants, polyurethane-based dispersants, polyphosphazene-based dispersants, and mixtures thereof, but is not limited thereto.

The solvent may be selected from the group consisting of water, an alcohol solvent, a halogen-containing hydrocarbon solvent, a ketone solvent, a cellosolve solvent, and an amide solvent, but is not limited thereto.

The coating composition may include inorganic nanoparticles; silane compounds; Surfactants; bookbinder; dispersant; and a solvent, preferably based on 100 parts by weight of the solvent, 5 to 20 parts by weight of inorganic nanoparticles; 20 to 50 parts by weight of a silane compound; 10 to 20 parts by weight of surfactant; 30 to 50 parts by weight of a binder; and 5 to 10 parts by weight of a dispersant. In the case of the above range, a synergistic effect of critical significance is expressed as a synergistic effect due to the interaction of each extract, and when out of the above range, the synergistic effect is rapidly reduced or almost absent.

The coating composition may include inorganic nanoparticles; silane compounds; Surfactants; bookbinder; dispersant; And after mixing the solvent, it is prepared by stirring at 100 to 150 rpm. The prepared coating composition exhibits a viscosity of 1,500 to 2,000 cps, and it is possible to maintain a constant shape when forming a coating layer on the surface of the substrate within the viscosity range, thereby facilitating coating using a known coating method.
