Description

Technical Field

[0001] This utility model relates to a fire-fighting smoke exhaust window for air-supported membrane buildings, belonging to the field of building smoke exhaust technology. Background Technology

[0002] Currently, most existing smoke exhaust windows use rigid materials such as aluminum alloy and PVC for their frames and sashes, and are opened and closed via mechanical devices. However, air-supported membrane structures are lightweight and flexible, relying on air pressure to maintain their shape. The installation and use of traditional smoke exhaust windows can damage the integrity of the air-supported membrane structure, leading to air pressure imbalance and affecting the stability of the building. Furthermore, traditional smoke exhaust windows are heavy, making it difficult for the flexible support structure of an air-supported membrane to bear their weight, resulting in extremely difficult installation. In addition, the sealing performance of traditional smoke exhaust windows is difficult to guarantee in an air-supported membrane environment, failing to meet the special airtightness requirements of air-supported membrane structures, easily leading to energy waste and ineffective smoke extraction in emergencies such as fires. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model provides a fire-fighting smoke exhaust window for air-supported membrane buildings that is simple in structure, reasonably designed, meets the smoke exhaust requirements of air-supported membrane buildings, and is easy to install and fix.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is a fire-fighting smoke exhaust window for air-supported membrane structures, comprising a rectangular frame and a door panel. A supporting base plate is installed on the bottom edge of the rectangular frame, and the supporting base plate is horizontally positioned. A cover plate is installed on the top edge of the rectangular frame, and side plates are respectively installed on the two side edges of the rectangular frame. The end faces of the supporting base plate, the cover plate, and the side plates are on the same plane, and the side plates are connected and fixed to the supporting base plate and the cover plate. The front end of the supporting base plate is connected to the door panel via a hinge. Connecting seats are respectively installed on the supporting base plate and the back of the door panel. An electric push rod is installed between the connecting seats, and the two ends of the electric push rod are respectively hinged to the connecting seats. Multiple aluminum plates are respectively provided on both sides of the rectangular frame, and the aluminum plates are connected by bolts.

[0005] Preferably, a reinforcing rib is provided between the supporting base plate and the rectangular frame.

[0006] Preferably, the door panel includes a front panel, a back panel, and a PVDF membrane bladder. The front panel has edge plates around its perimeter, which are perpendicular to the front panel. The back panel is located on the back of the front panel, and the back panel has limiting support strips around its perimeter. A PVDF membrane bladder is disposed between the back panel and the front panel. When the PVDF membrane bladder is inflated, it forms an annular PVDF membrane ring located between the limiting support strips and the edge plates. Sealing plates for supporting the PVDF membrane ring are provided on the supporting base plate, cover plate, and side plates.

[0007] Preferably, the sealing plate is further provided with a sealing film.

[0008] Compared with the prior art, the present invention has the following technical effects:

The installation process will not damage the air-supported membrane, ensuring the integrity and stability of the air-supported membrane building and overcoming the problem that traditional smoke exhaust windows cannot be applied to air-supported membrane buildings. In addition, the overall weight is greatly reduced, the air-supported membrane structure can easily bear the load, reducing the installation difficulty, and at the same time, it will not have a significant impact on the air pressure balance of the air-supported membrane.

[0010] 2. This utility model uses sealing film and inflatable sealing airbag for sealing, which significantly improves the sealing performance of the smoke exhaust window and meets the high airtightness requirements of air-supported membrane buildings. In daily use, it effectively prevents energy loss and reduces operating costs. In emergency situations such as fires, it can effectively prevent the spread of smoke and create favorable conditions for personnel evacuation and fire fighting and rescue.
