Fireproof thermal insulation window

Abstract

The invention discloses a fireproof thermal insulation window, and belongs to the technical field of windows for buildings. The window comprises a window frame and a glass panel embedded in the mounting groove in the window frame. The window frame is divided into two annular cavities, and fireproof mud is arranged in the annular cavities at the outdoor end, thermal insulation strips are arranged in the annular cavities at the indoor end; the water absorption cotton, a fireproof expansion sealing strip and a graphite sealing strip are arranged between the mounting groove of the window frame andthe glass panel, the water absorption cotton is arranged on the side wall, close to the outdoor end, of the mounting groove, the fireproof expansion sealing strip is arranged on the bottom surface ofthe mounting groove, the graphite sealing strip is arranged on the side wall, close to the indoor end, of the mounting groove; the fireproof thermal insulation window further comprises a water delivery pipe connected with an external water source, the output end of the water delivery pipe comprises a plurality of spray heads; a plurality of flow guide grooves are formed in the outer surface of the glass panel, and the tops of the flow guide grooves are correspondingly connected with the spray heads. The fireproof thermal insulation window has the beneficial effects that the fire can be stablyresisted, the fire resistance and the heat insulation performance of the window are guaranteed, an active cooling mechanism is provided, and the smoke resistance performance of the window is improved.

Description

technical field [0001] The invention belongs to the technical field of windows for buildings, and in particular relates to a fire-proof and heat-insulating window. Background technique [0002] Windows are important equipment to improve the ventilation effect and lighting effect inside a building. They are widely required in various buildings and are one of the indispensable components of buildings. Fireproof and heat-insulating windows are one of them, which are mainly composed of window frames and fireproof glass, which can isolate and prevent the spread of fire. [0003] The way for the exterior wall fire to evolve into a three-dimensional fire is that the flame or radiant heat enters the room through the window, thereby igniting the combustibles in the room, and the indoor fire spreads to other rooms along the corridor, resulting in three-dimensional combustion. Therefore, when a fire occurs, if It can block the propagation path of flame and radiant heat, so as to preve...

[0003] The way for the exterior wall fire to evolve into a three-dimensional fire is that the flame or radiant heat enters the room through the window, thereby igniting the combustibles in the room, and the indoor fire spreads to other rooms along the corridor, resulting in three-dimensional combustion. Therefore, when a fire occurs, if It can block the propagation path of flame and radiant heat, so as to prevent the spread of fire and prevent three-dimensional combustion. The ordinary windows of ordinary civil buildings do not have the function of fire prevention. Even if they are closed, the glass of ordinary windows will also Explosion occurred, unable to prevent the fire from spreading

[0004] At present, the profiles used in the existing exterior walls and windows are mostly broken bridge aluminum profiles, aluminum alloy profiles, wood-clad aluminum profiles, aluminum-clad wood profiles, PVC plastics, wood and wood-plastic. These materials have low melting points, such as the melting point of aluminum. It is 660 degrees, and the burning temperature of fire-proof and heat-insulating windows is 1100 degrees, so it is difficult for these profiles to achieve fire-resistant integrity; The ability to prevent the penetration of flames and heat or the emergence of flames on the unfired side for a certain period of time

However, when the current fire-proof and heat-insulating windows encounter a fire, the flame will increase the temperature of the fire surface of the window frame, and the heat will be transferred at this time. It is difficult to guarantee safety; secondly, the current fire-proof windows do not have an active cooling mechanism, and the operability is extremely poor; at the same time, the current windows are poorly sealed and cannot block the flow of smoke in the event of a fire
