Description

Roof structure of building

The present invention relates to a roof structure of a building, and more particularly, while facilitating the construction work of the sandwich panel. It relates to a roof structure of a building that can prevent the spread of fire through the connection between sandwich panels in case of fire and improve the fire resistance function by minimizing structural deformation of the sandwich panel.

Sandwich panel is a kind of building material and is widely used because it does not have excessive construction cost and is easy to install and remove. In general, a sandwich panel has a coupling structure in which a filler having thermal insulation and insulation performance is inserted between an outer plate and an inner plate, and a building is constructed by connecting a plurality of sandwich panels having a certain size and width.

Since these sandwich panels are light and easy to install and release, they have good workability.

Sandwich panels are produced in a variety of ways, such as flame-retardant panels that do not burn well, fire-resistance-recognized panels that withstand fire well, and sound-absorbing panels, depending on the application. .

Among these sandwich panels, the sandwich panel for roof is constructed to be supported by the roof structure. Recently, the roof structure should be constructed with a fire resistance certification structure according to the Building Act for safety.

When installed, the longitudinal length (L in FIG. 3) of the supplementary panel 2000 may be formed to be 0.1 or more to 0.4 times or less of the longitudinal length (W in FIG. 3) of the sandwich panel 1000. . For example, when the longitudinal length (W in FIG. 3) of the sandwich panel 1000 is 1000 mm, the longitudinal length (L in FIG. 3) of the complementary panel 2000 may be formed to be 100 mm or more and 400 mm or less.

Specifically, when the longitudinal length (L in FIG. 3) of the complementary panel 2000 is 100 mm, the complementary panel 2000 is spaced apart from each other at a predetermined interval, so the longitudinal length of the sandwich panel 1000 (W in FIG. 3) is Up to nine can be installed within 1000mm, and when the longitudinal length (L in FIG. 3) of the supplementary panel 2000 is 400mm, the supplemental panel 2000 can be installed up to two.

If the longitudinal length (L in FIG. 3) of the complementary panel 2000 is less than 0,1 times the longitudinal length (W in FIG. 3) of the sandwich panel 1000, the structural strength of the connection portion of the sandwich panel 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 sandwich panels, and deformation such as the sandwich panel twisting and opening occurs, 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 supplementary panel 2000 exceeds 0.4 times the longitudinal length (W in FIG. 3) of the sandwich panel 1000, the lower part of the supplementary 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 supplementary panel 2000 .

Therefore, as the cold air from the second panel installed outside due to the strong cold is conducted to the first panel through the supplementary panel, condensation occurs on the roof structure of the building as a whole, impairing a pleasant environment inside the building A problem of increasing maintenance cost and increasing harmful bacteria such as mold may occur.

Although not necessarily limited thereto, the longitudinal length (L in FIG. 3) of the supplementary panel 2000 is formed to be 0.1 times or more and 0.2 times or less of the longitudinal length (W in FIG. 3) of the sandwich panel 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) of the building according to an embodiment of the present invention, the complementary panel (2000) has a longitudinal length (L in FIG. 3) of the supplementary panel (2000) is the first panel of the installed sandwich panel (2). (1100) and the charging unit 1300 and the second panel 1200 in the state installed on one side of the vertical length of the complementary panel 200 (H in FIG. have.

If the longitudinal length (L in FIG. 3) of the supplementary panel 2000 is less than 0.3 times the vertical length (H in FIG. 3) of the supplementary panel 200, the structural strength of the connection portion of the sandwich panel 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 sandwich panels, and deformation such as the sandwich panel twisting and opening occurs, 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 supplementary panel 2000 exceeds 0,5 times the vertical length (H in FIG. 3) of the supplementary panel 200, the lower part of the supplementary panel is the second Since the first panel and the second panel are 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 supplementary panel 2000, so the second panel installed outside due to the strong cold As the cold air of the air conducts to the first panel through the supplementary panel, condensation occurs on the roof structure of the building as a whole, impairing a pleasant environment inside the building, increasing the maintenance cost of the building due to the condensation, and increasing harmful bacteria such as mold This can happen.

The pressure coupling part 3000 of the roof structure of a building according to an embodiment of the present invention is a first pressure coupling part 3100 that is contact-coupled to the upper portion of the cover part 1270 , one side of the first pressure coupling part 3100 . The second pressure coupling part 3200 and the first pressure coupling part 3200 and the first pressing part are formed to be inclined vertically while a part is bent to a shape corresponding to the second fixing part 1230 so as to be contact-coupled to the second fixing part 1230 at the tip. A third pressure coupling part which is formed to be inclined vertically downwardly while being bent in a shape corresponding to the third fixing part 1280 so as to be contact-coupled to the third fixing part 1280 at the other end of the coupling part 3100 . (3300).

As such, in the roof structure of a building according to an embodiment of the present invention, the sandwich panel is fixed so that the gap between the pre-installed sandwich panel and the adjacent sandwich panel is in close contact by detachably installing the pressure coupling part at the connection part of the sandwich panel to finally connect the sandwich panel. The complementary panel 2000 coupled to the sandwich panel is also closely coupled with the other side of the first panel, the charging part, and the second panel of the sandwich panel adjacent to one side of the first panel, the filling part, and the second panel of the previously installed sandwich panel, thereby causing a fire. In this case, it is possible to further improve the fire resistance function by further preventing the spread of fire by fire.

The first panel 1100, the second panel 1200, the supplementary panel 2000, and/or the pressure coupling part 3000 of the present invention use a coating composition having an excellent anti-contamination effect to form a coating layer to prevent contamination. can represent

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.
