Description
Technical Field
[0001] The utility model belongs to the technical field of safe evacuation equipment, and in particular relates to a pressure relief escape window device suitable for pressurized buildings. Background Art
[0002] Escape windows are generally used in public transportation such as buses, high-speed trains, subways, and ships. When an accident occurs and people cannot evacuate through doors, they can use escape windows to evacuate. In the field of architecture, there is no concept of escape windows, and they are generally fire rescue windows. Regardless of whether it is an escape window or a fire rescue window, the key technical point of its design is that it should be easy to open the escape window for evacuation in the event of an emergency.
[0003] At present, the most widely used design form of escape window is to use easily breakable glass, and escape by using a window breaker hammer to break the escape window in an emergency; there are also other forms, including the form of breaking the window using vacuum principle or mechanical principle, and the form of escape window opened by mechanical means.
[0004] However, the existing escape window forms are not suitable for pressurized buildings. Pressurized buildings are mostly used in plateau areas. They pressurize the building to make its pressure environment the same as that in low-altitude areas, thereby effectively alleviating altitude sickness. The indoor and outdoor pressure difference of pressurized buildings can theoretically reach 50Kpa. Under this pressure difference, the glass strength of the window is relatively high, and it is difficult to use conventional window breaking methods, and the window breaking time is long. In addition, due to the airtightness of pressurized buildings, if the conventional escape window mechanical opening solution is adopted, its opening force is large and it is difficult to open normally.
