Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguishing structure,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heat insulating structure to be installed on an outer wall of a building, and more particularly, to an external heat insulating structure for preventing fire from diffusing an inorganic heat insulating material to an outer wall of a building.

As the energy used to maintain the thermal environment conditions in buildings accelerates the global warming, policies and technologies for reducing energy use of buildings are being developed and distributed all over the world. In particular, the outer insulation method, which shows the best insulation performance, is widely used in energy saving houses.

In addition, in the energy conservation standards of domestic buildings, the application of the external insulation method such as the induction of the external insulation method of the building is on the trend.

The adiabatic method is a method of attaching an insulation material to the outside of a structural wall of a building and finishing it by using a separate finishing material, and it can be classified into a dry type and a wet type according to the method of adhering the insulation and the method of installing the finishing material. Especially, since the construction cost is economical, the Exterior Insulation Finish System (EIFS), which is the most used among the external insulation methods, is a typical external insulation method. Since the insulation performance of the external insulation method depends on the insulation used, insulation is very important. EPS (Expanded Polystyrene) insulation with the most economical and excellent insulation performance is the most used, and polyurethane insulation is also widely used for excellent insulation performance.

The adiabatic method is a wet finishing method in which a heat insulating material is adhered to an outer wall body using mortar and a finish is made of a liquid material, a heat insulating material is attached to an outer wall body using an adhesive and a fixing bracket, , A stone, a cement panel, or a board by using a fixing bracket.

However, in the wet finishing method, deformation repeatedly occurs due to repeated external force such as wind, and thus the occurrence of cracks and adherence of the mortar having the heat insulating material and the outer wall body is lowered, And the dry finishing method is to fix the metal frame by fixing the metal frame after removing the heat insulating material at the fixed position to fix the metal frame for the finishing material. It is constantly being raised.

In addition, although the organic insulation used mostly as the outer wall insulation has an excellent heat insulation performance, it is pointed out that it is a cause of various fire accidents because it is vulnerable to fire. Inorganic insulation materials such as glass wool and mineral wool, which have excellent fire performance, are used for fire-sensitive areas in organic insulation materials. However, they are used as insulation materials for exterior wall, waterproofing and moisture resistance. EPS insulation is still the most widely used.

However, due to frequent frequent external wall fire accidents and eventual damage to people, the use of exterior walls of organic insulation materials such as EPS insulation materials is being changed from the design stage of the building in order to improve social safety.
