  At fire sites in densely populated residential areas, to prevent the spread of fire to the next house in the vicinity of the fire source, make the fire source building a large amount of water discharge or make the next house water discharge and make it harder to burn. However, depending on the location, it may not be possible to prevent the spread of fire completely due to the discharge of the fire, or the discharge of water may cause the building to be submerged or be damaged, or unfortunately it may be destroyed just by being the fireside's next home. There is also. In addition, once a forest fire (such as a forest fire) occurs, it can not be easily digested and can cause widespread damage.

  The present invention is an apparatus which solves the above-mentioned problems and prevents fire spreading by installing a heat-resistant sheet around a wooden house, a structure such as a cultural property building, and a house at the foot of a mountain in an emergency.

  In the apparatus of the present invention, the heat-resistant sheet has a slit (slit), which can escape the wind and can prevent fire powder and flames on the cut sheet surface having a further length.

  Basically, this device installs the heat-resistant sheet in the wind of the structure, but there are fixed type and movable type as a method, and both can be stored in a space-saving manner because they are decomposition type at the time of flat.

  The major difference between the present invention and the conventional device is that the heat-resistant sheet that has been set contains a plurality of cuts, and the cuts receive wind pressure when the wind is strong and the firefighters or residents release water to the heat-resistant sheet. It is a revolutionary invention that can prevent the spread of fire caused by fire powder and the like.
