Description

[0001] Dry fire-proofing assembly of steel structure [0002]

The present invention relates to a fireproof coating structure for securing the refractory performance of a steel structure, and more particularly, to a fireproof coating structure for securing the fire resistance of a steel structure, To a dry-type fire-resistant coating structure of a steel structure capable of attaching a gypsum board by a dry method using only an edge channel and a fixing pin around the structure.

Generally, in the construction method using a steel structure, a fireproofing method for preventing the warping of steel due to fire or the like in the construction of a steel column or a steel frame is institutionalized.

In the conventional steel structure refractory method, a method of applying a refractory paint on the surface of the steel material or covering the periphery of the steel material with a gypsum board or the like is used to weaken the heat conduction. In the method of covering the periphery of the steel material with the gypsum board, A guide for fixing the board around the steel member becomes necessary.

For example, in the case of a steel column, a plurality of guides for receiving and supporting the upper and lower ends of the gypsum board are installed on the ceiling and the floor after the steel material is set up, and a gypsum board is inserted into each guide, To be connected by a reinforcing material. Therefore, the refractory method has a complicated process and requires a lot of working time, so there is a problem of extending the air and increasing the construction cost.

In this connection, the gypsum board can be easily installed on the steel without installing a guide in the Korean Registration Practice No. 20-0307492 (2003.04.04 registration, hereinafter abbreviated as "Patent Document 1"), And a fire-resistant structure of a steel structure capable of reducing a construction cost are known.

According to Patent Document 1, a separate fixing clip is fitted to the steel material of the H-shaped section, and a fixing channel is fixed to form an air layer. Then, the gypsum board is fixed and installed to prevent deformation due to a rise in temperature of the steel during a fire I can do it.

However, in the above known prior art, since the fixing clip is applicable only when the steel material is the H-shaped steel, it is possible to use other types of steel materials other than the H-shaped steel, that is, other shapes such as a c- It is impossible to apply it to the construction work in which the steel material of the present invention is used.

Recently, a modular construction method in which a section steel is continuously used is utilized. In the modular construction method, other steel structures such as a c-section steel, a C-section steel or a square steel are used, and such a section steel or C- In the case of square shape, since the above-mentioned conventional fixing clip can not be inserted as it is, it is necessary to attach the fixing clip by welding and then to perform a separate process of additionally rust-proofing and painting, (Spraying, paint), which causes disadvantages such as inability to construct during the winter season, addition of a separate board finishing process, delay in construction, and cost increase.

Therefore, it is urgent to develop a method capable of satisfying fire resistance, economical efficiency, and efficiency even in other types of steel frame structures such as a c-section steel or a C-section steel or a square type in which a fixing clip can not be inserted.
