Description

Prevention of fire spread of building exterior wall structure}

The present invention relates to a fire diffusion prevention outer wall structure of a building, and more particularly, to a fire diffusion prevention outer wall structure of a building to prevent the fire generated from the lower floor to spread to the upper floor along the windows installed on the balcony. .

In general, it is legal to use a space that expands the balconies of a building such as an apartment building to increase the area of a living room and a room. As the outer wall of the balcony is formed as a direct wall structure of the living room and the room, the fire of the lower floor is easily spread to the upper floor in case of fire. In order to prevent the spread of fire, mandatory regulations are required to install fireproof panels with a height of 90 cm or more on the balcony side in order to prevent the spread of fire.

As a conventional fire protection device, a plurality of heat sensing devices are installed for each generation of a multi-family house, and when the heat is sensed above a predetermined temperature, the sprinkler is operated to suppress the flame.

The sprinkler system can effectively deal with the small scale of fire, but since the flames generated in case of gas explosion and intentional arranging are large and instantaneously spread, not only the generation (lower layer) where the fire occurs. Rather, the flames were easily spread to the upper floors on the outside balcony, which led to enormous property damage and human injury.

In order to solve the above problems, a fireproof plate made of an opaque material was installed in accordance with the mandatory provision of a fireproof board having a height of 90 cm or more on the balcony side according to the Building Act Enforcement Decree according to the expansion of the balcony to prevent the fire from spreading to the upper floor.
