Fire-resistant sunshade and energy-saving integrated window

Abstract

The invention relates to the technical field of building door windows, in particular to a fireproof and sunshade energy-saving integrated window. The fireproof and sunshade energy-saving integrated window comprises a fireproof and sunshade roller curtain and an energy-saving heat preservation window. The fireproof sunshade roller curtain comprises a roller curtain box, a reel, guide wheels, guiderails and a fireproof curtain sheet. The reel and the guide wheels are mounted in the roller curtain box, the guide rails are mounted on the outer wall of a wall and located on the two sides of an opening of the wall, the reel is wound with the top end of the fireproof curtain sheet, the bottom end of the fireproof curtain sheet penetrates through the guide wheels to extend into the guide rails, and the the fireproof curtain sheet can be driven by the reel to penetrate through the guide wheels to rise and fall in the guide rails. The fireproof and sunshade integrated window can meet the requirement for energy conservation of a building, has the sun-shading effect, and can reduce the situation that outdoor light rays and heat are transmitted into the indoor space. Meanwhile, the fireproof and sunshade integrated window has a good sealing effect, the fire-resistant time can be prolonged when a fire happens, the effect that a flame and smoke are prevented from entering is achieved, and the losses caused by the fire can be reduced to the largest extent. Meanwhile, the fireproof and sunshade integrated window can automatically handle with the fire, and is convenient to check and maintain.

Description

technical field [0001] The invention relates to the technical field of building doors and windows, in particular to an integrated window for fire protection, sunshade and energy saving. Background technique [0002] The area of ​​housing built in my country every year is as high as 1.6 to 2 billion square meters. Among the existing buildings of more than 40 billion square meters, buildings with high energy consumption account for 99%. Although the area of ​​windows on the building only accounts for about 10% of the building's external area on average, it accounts for 44.4% of the energy loss of the entire building. Correspondingly, the U-value of the old-fashioned window system can be increased by more than 46% with the help of external sunshade roller shutters, but the external sunshade roller shutters will greatly reduce the energy conversion of air through the window hole, external sunshade roller shutters and hollow glass windows Form a double barrier to block air conve...

Problems solved by technology

Although the area of ​​windows on a building accounts for only about 10% of the building's exterior area on average, it accounts for 44.4% of the energy loss of the entire building.

Correspondingly, the U-value of the old-fashioned window system can be increased by more than 46% with the help of external sunshade roller shutters, but the external sunshade roller shutters will greatly reduce the energy conversion of air through the window hole, external sunshade roller shutters and hollow glass windows Form a double barrier to block air conversion, so that the application of a set of external sunshade roller shutters may cause a difference of ±3-4°C between the building and the same room temperature without roller windows, and it can be used in the case of heat insulation or heat preservation. It can save energy by 40%. However, most of the existing external sunshade roller blinds are made of aluminum alloy, with a wall thickness of only 0.5mm. In addition, the melting point of aluminum is only 660 degrees, which will not play a role in fire prevention when the building is on fire.
