Abstract
The invention relates to a pressure-reducing fireproof door in a subway tunnel, and belongs to safety equipment in the field of subway traffic. The pressure-reducing fireproof door in the subway tunnel is characterized in that the pressure-reducing fireproof door comprises a door frame, a side hung door sash, spine-type flow guidance sealing plates on the periphery of an inner frame of the side hung door sash, a sliding door plate in the door sash and sliding supporting and returning mechanisms; when the sliding door plate is pushed by air pressure to move, sealing bars on the periphery of the sliding door plate move along with the spine-type flow guidance sealing plates fixed to the inner frame of the side hung door sash for a period in the spine-type flow guidance sealing plates and keep away from the flog guidance grooves in the sealing plates so that high-pressure airflow of one side of the sliding door plate can flow into the other side, the sliding door plate stops moving and returns back to a middle sealing position under the action of a return spring when the air pressures on the two sides are balanced, and the sliding door plate will move left and right and back and forth in the middle sealing position no matter the air pressure of which side of the sliding door plate is larger. The pressure-reducing fireproof door in the subway tunnel is reasonable in structure, large alternating pressure difference will not be generated on the fireproof door through potential energy of piston wind, and therefore the piston wind is prevented from damaging the fireproof door body structure.
Description
Technical field
The present invention relates to a kind of labeled door, particularly relate to a kind of be specifically designed in subway tunnel, use can bear at least labeled door of 4kPa alternation Piston Action Wind pressure.
Background technology
Subway tunnel labeled door is a kind of two doors between tunnel that are arranged on, and mainly contains two kinds of single open-door and double doors, and in original correlation standard, its Main Function is fire prevention, in case of emergency evacuates passenger.Subway tunnel is former is all common fire resistance steel door with labeled door.This type of labeled door all can not meet metro environment demand from many-sides such as structure design, five metals configuration, installation forms.In subway circulation process, the continuous opposite house body of Piston Action Wind meeting produces positive/negative-pressure impact and subway tunnel inside is comparatively moist, and common fire resistance steel door easily produces distortion and comes off, and has serious quality and potential safety hazard.
summary of the invention
The object of this invention is to provide a kind of for the robust labeled door of subway tunnel, this Fireproof door structure is reasonable, consider that a body can not destroy very soon under the effect of Piston Action Wind alternating pressure, just can not allow Piston Action Wind on door body, set up larger pressure, in the vertical hinged door leaf of the buffer structure principle that has a window according to aerodynamics in tunnel in labeled door, design a fan translation door-plate, this door-plate outer rim surrounding has asbestos seal bar, weather strip is close on the backbone type water conservancy diversion sealing plate inner surface of vertical hinged door leaf frame inner wall surrounding installation, in the middle of this backbone type water conservancy diversion sealing plate, it is isolation strip, both sides, isolation strip symmetry has the guiding gutter of oblong shape, translation door-plate is done translational motion at the promotion lower compression return spring of Piston Action Wind pressure, weather strip by the sealing station of intermediate isolating band to the low side shifting of pressure, in moving process, weather strip has left sealing station and has arrived guiding gutter position, high pressure draught enters low pressure one side by guiding gutter, now just be equivalent to open a buffer window on tunnel wall, the stream pressure of translation door plate hight air pressure one side lowers immediately thereupon, when the air pressure balance of translation door-plate both sides, translation door-plate is got back to the sealing station of intermediate isolating band under return spring effect, when Piston Action Wind pressure direction changes, translation door-plate moves round about, its buffering depressurization is with aforementioned.
The object of the invention is to realize by buffering decompression technology scheme, subway tunnel decompression type labeled door of the present invention is by doorframe, hinge, vertical hinged door leaf, door closer, door lock and be arranged on the backbone type water conservancy diversion sealing plate of vertical hinged door leaf frame inner wall surrounding and translation door-plate that backbone type water conservancy diversion sealing plate inner surface arranges and its support that slip return mechanism forms.
Described doorframe is conventional fireproof door frame structure.
Described hinge, door closer, door lock are general fire prevention accessory.
Described vertical hinged door leaf is comprised of the support slip return mechanism of framework and backbone type water conservancy diversion sealing plate and translation door plate and translation door-plate.
Described backbone type water conservancy diversion sealing plate is that shape is isolation strip as its centre of vertebrae, and both sides, isolation strip symmetry has the guiding gutter of oblong shape, and each guiding gutter separates.
Described translation door-plate is the door leaf of making according to labeled door standard, at its surrounding outward flange, is provided with asbestos seal bar, at Qi Sijiao, is provided with and supports slip return mechanism.
Described support slip return mechanism is comprised of gripper shoe, optical axis, linear bearing, Linear bearing fixing seat, return spring.
Subway tunnel decompression type Fireproof door structure of the present invention is reasonable, energy is the Piston Action Wind pressure of cushioning effect on door body effectively, the direction of considering Piston Action Wind pressure is alternation, under labeled door closed condition, translation door-plate can move around to have played and in tunnel, dynamically arranges buffer structure window, simultaneously when breaking out of fire translation door-plate outer rim asbestos seal bar and backbone type water conservancy diversion sealing plate have played the effect that prevents from altering fiery smoke blowing.
The use of subway tunnel decompression type labeled door and general labeled door, without any difference, rotate and pull labeled door is opened, and the labeled door of loosing one's grip is automatically closed under the effect of door closer.
