Description

Emergency escape pressure-bearing door convenient to pass Technical Field The utility model relates to the technical field of pressurized building pressure-bearing doors, in particular to an emergency escape pressure-bearing door convenient to pass. Background The indoor air pressure of the pressurized building is generally higher than the outdoor environment air pressure by tens of kilopascals to tens of kilopascals, and the emergency escape door applied to the pressurized building can keep air tightness and bear the load of air pressure difference. The emergency escape door is used as a safety exit, and the height of the doorsill is as low as possible so as to be convenient for passing. However, the bottom door frame of the existing emergency escape door needs to extend upwards to extrude the sealing strip to form a higher door threshold (generally 4 cm), which is not beneficial to traffic. In addition, most of the existing emergency escape doors are inwards opened, and the requirement of outwards opening the emergency escape doors is not met. The other emergency escape door of the existing supercharged building adopts a mode that a zipper type airtight film and a ventilation pressure-bearing door are combined, the periphery of the zipper type airtight film is fixed on a door frame through an airtight component, a sealing zipper is arranged on the zipper type airtight film and used for emergency pressure relief and personnel evacuation, however, the sealing zipper cannot be arranged at a high level, so that the airtight film is left at the bottom to form a higher threshold (generally 4 cm), and the traffic is not facilitated. In summary, it is necessary to develop an emergency escape pressure-bearing door convenient for passing so as to solve the problem that the emergency escape door in the existing supercharged building has a higher threshold and is not beneficial to passing, and most of the emergency escape doors are inwardly opened so as to not meet the requirement of the emergency escape door for outward opening. Disclosure of utility model The utility model aims to provide an emergency escape pressure-bearing door convenient to pass, which has the following specific technical scheme that: The emergency escape pressure-bearing door convenient to pass comprises a pressure-bearing door leaf, an airtight membrane and a door frame, wherein one side of the pressure-bearing door leaf is hinged with the door frame and can be outwards opened relative to the door frame, the airtight membrane is an airtight membrane which can be torn by hand and is arranged in a gap when the pressure-bearing door leaf is closed with the door frame, the door frame is a closed frame, and the top of the bottom end of the door frame is flush with the building ground. Optionally, the pressure-bearing door leaf comprises a lock tongue, and a lock groove matched with the lock tongue is arranged on the door frame. Optionally, the number of the lock bolts is at least two, and the lock bolts are arranged on the pressure-bearing door leaf at equal intervals.
