The present invention relates to fire-fighting windows, and more particularly to fire-fighting windows that can form a protective film for protecting the high-pressure injection of water and firefighters.

In order to cope quickly and completely with the increasing fire in recent days, the modernization, advanced and practical use of equipment is urgently needed. In addition, according to the current fire site survey results, the combustion rate is low as the waterproof start time is short, so it is well known that the rapid start of waterproof can exert a great effect of the combustion prevention.

Such water is waterproofed by a pipe installed at the end of the connection hose connected to the fire engine. Therefore, the waterproof distance is determined according to the characteristics of the pipe, thereby affecting the fire extinguishing function.

In view of this, patent publication No. 1997-0058739 discloses a vortex type safety window. The disclosed safety window consists of a head, a middle gear, a pressure regulator for regulating pressure, a safety device for preparing for abnormal pressure, a support spring for the operation and support of the safety device, and an impact of the safety window. To connect rubber ring, safety device and pressure control device to alleviate pressure, and to control movement limit, screw type lower part of pressure control device so that waterproof water can return to vortex type, and screw type It has a configuration composed of connecting supports.

And Utility Model Registration No. 0243380 discloses a radiation pipe for fire fighting. The fire extinguishing pipe is disclosed in the general fire-fighting radiation pipe of the structure consisting of a hose insert, a radiation control unit, a current transformer, a central body, and a current flow sheet, wherein the current-flow sheet constituting the current transformer is threaded at its inner surface.

As shown in the above-described embodiment, the fire extinguisher has only a structure capable of waterproofing the water or spreading the water by widening the spray angle, so that the firefighter holding and extinguishing the fire extinguisher during a large fire, that is, a relatively large firepower, radiates heat. There is a problem that can not be carried out by the fire extinguishing, and there is a risk inherent to firefighters such as exposure door burns from the flame.

 In particular, the hose connected to the hose is sprayed water at high pressure has a problem that the hose swings in the shape of meandering by the injection pressure through the pipe in the process of waterproofing. The fluctuations of the hoses installed with these pipes are a great drain on the firefighters holding the pipes for waterproofing the fire site. In addition, when firefighters are supplied from fire trucks, the pressure of the firefighters may not be kept constant, and thus the pressure on the pipes may not be constant, and a considerable amount of pressure may be suddenly applied. In this case, firefighters holding the windows may be injured unless the pressure applied to them is effectively distributed.

In particular, even if the waterproof through the sandwich panel using the pipe window as in the above embodiment, the problem caused by the radiant heat when extinguishing the inside of the building through the flammable material or sandwich panel between the sandwich panel and the firefighters are exposed to the danger by this radiant heat. There is a problem that cannot be prevented fundamentally.
