Description

[0001] Architectural Printed Steel-sheet Structure [0002]

The present invention relates to a printed steel sheet structure for construction, and more particularly, to a printed steel sheet structure for construction, which has a structure for being used as an interior and exterior material of a building using a printed steel sheet (pattern or color steel sheet) while maintaining smoothness and aesthetics well. Lt; / RTI >

In the case of conventional interior and exterior wall coverings, gypsum board and waterproof plywood have been recognized as major materials in the construction market.

However, in the case of gypsum board or water-resistant plywood, since there is a lack of aesthetic appearance, it is possible to apply a bond or paste on a gypsum board or a water-resistant plywood and apply paper wallpaper or by applying a sheet of synthetic resin- The interior and exterior finishes were complemented by aesthetics.

However, the following problems have been continuously pointed out in construction sites.

- When applying paper wallpaper or sheet paper, a large amount of bond is used.

- Gypsum board and water resistant plywood are very vulnerable to moisture, causing mold and construction performance to deteriorate rapidly in the event of condensation.

- Domestic plywood, wallpaper, and sheet are very vulnerable to fire.

Particularly, in the case of final finishing materials, the regulation of fire retardancy has been strengthened recently by the amendment of the Enforcement Ordinance of the Korean Building Construction Act (Feb. 5, 2015), thereby increasing the necessity of constructing interior and exterior materials with flame retardant structure. However, Method has a limitation in ensuring flame retardancy.

On the other hand, a technique has been devised to apply a gypsum board and a waterproof plywood to the other outermost finishing material as a flame retardant material. However, when a flame retardant material is used only as a finishing material in the existing construction method, the following problems And it was not practically applied, and most of them were stopped at the experimental stage.

- If the floor is made of gypsum board and waterproof plywood, it is relatively easy to apply the finishing material such as wallpaper and sheet paper in a soft and soft material. However, since most of the materials having different flame resistance are strong in strength and low in flexibility, It is very difficult to maintain proper bonding strength.

- In case of finishing, straightness and smoothness are very important, but in most cases where wallpaper and sheet paper finish are applied, the quality of straightness and smoothness is determined in gypsum board and waterproof plywood work, Smoothness is determined. However, when the finishing material is not a wallpaper or a sheet paper, the strength of the gypsum board is comparable to that of the waterproof plywood, or rather the strength thereof is stronger so that the smoothness and straightness of the work can not be obtained. In particular, in case of gypsum board, a phenomenon occurs in which gypsum as core and paper as sheath are separated.

- In the case of using existing liquid bond, when using flame retardant material which is not heavy than wallpaper and sheet paper, liquid bond hardens and it is very difficult to fix up to the point where bonding force is exerted. Actually, In most cases, panel assemblies are produced by joining gypsum boards or flameproof materials with flame-retardant materials in the assembly plant in most cases, and they are attached in the field, It becomes very difficult to adapt to the fluidity.

In this way, there are problems in construction, flame retardancy, straightness, smoothness, etc., which have been a problem in the existing method at present, but there is no practical solution to this problem.
