The invention relates to the field of elevator equipment, in particular to an elevator side-opening type fireproof landing door.
Background
With frequent occurrence of accidents of elevators, nowadays society pays more and more attention to accidental protection of elevators, and in order to cope with the accidental situation of fires in buildings, landing doors with fireproof function are generally required to be installed.
In the existing side-opening type landing door, a door gap sealing structure is in a fixed right-angle shape between a shutter door plate and a slow door plate. Compared with a common side-opening landing door, the fireproof landing door has the advantages that the fireproof landing door has to meet the performance requirements of national standard on completeness, heat insulation and the like, and the side-opening landing door needs to increase the front and back gaps of the door plate so as to install the right-angle lapped door seam baffle. The space occupied by the lap joint part of the door gap baffle is positioned between the shutter door plate and the slow door plate, correspondingly, the width of the sill must be increased, the front-rear distance of the door sill hanging plates must be increased, the width of the sill is increased, the front-rear distance of the door sill hanging plates must be increased in cooperation with the arrangement of the door plates, more hoistway space is occupied, the cost of the door sill and the sill is increased, and the specification is increased. In addition, current fire prevention side-opening layer door, when closing, still have the gap to expose between shutter door plant and the slow door plant, lead to the fire prevention effect relatively poor.
At present, the sill and sill structure on the door of current elevator landing door system are comparatively fixed to the specification is general relatively, how to design out a side opening formula fire prevention landing door and can compatible current landing door system, and have fine fire prevention effect, be the problem that needs the solution at present urgently.
