DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire protection system for a building and a gutter for fire protection, which can delay or prevent the spread of fire when a neighborhood fires.

[0002]

2. Description of the Related Art Conventionally, an automatic fire extinguisher is associated with a sprinkler, but this is an automatic fire extinguisher for a fire that has occurred indoors. Except for special buildings, there was no equipment to prevent the spread of fire in ordinary private houses. In urban houses, the gap between the building and the neighborhood is becoming narrower year by year, and there are many wooden buildings. It is said that fires often start and spread from the attic.

[0003]

The disadvantage of the conventional fire protection system is that it is not installed in ordinary home buildings because it is expensive even though it is not known whether it will be used once every several decades. there were.

The present invention has been made in view of the above-mentioned conventional drawbacks,
It can be installed at low cost without damaging the appearance of the building, and can efficiently prevent fire from entering under the eaves at the beginning of a fire, effectively delaying or preventing the spread of fire. It aims to provide gutters.
