Description
Technical field
The present invention relates to a kind of elevator door, point fireproof landing door in particularly a kind of elevator.
Background technology
Along with the Frequent Accidents of express elevator, the accident of elevator is protected more and more heavier by society now
Depending on, in order to tackle this accident of building breaking out of fire, existing elevator be commonly installed have anti-
The layer door of fire function, this kind of layer door generally uses the gap reduced between layer door and door pocket,
Enter the quantity in car with reduction flue gas along gap, reach fireproof function.And it is current
The fireproof landing door that flameproof effect is good on the market is typically with the steel plate structure of bilayer, and its structure is multiple
Miscellaneous, fabrication and installation difficulty, and also its cost is the most of a relatively high.There is also one the most on the market
A little fireproof landing doors, install sealing member, with between off-set layer door and door pocket between layer door and door pocket
Gap, but this sealing member is difficult to well carry out close by the gap between layer door and door pocket
Envelope, and the gap for another place does not process, and causes the flue gas can be from other ground
Side is penetrated into, although the simple in construction of this kind of fireproof landing door, but its flameproof effect is the best.Simultaneously
Existing elevator door is to use metallic plate, and its heat-conducting effect is good, when breaking out of fire deck door
Being easy to carry out heat transfer, in order to overcome this difficulty, existing technology is to arrange on door-plate
Heat-barrier material, but heat-barrier material is due to fixing, is often easy to after by high temperature
Come off, thus reduce heat insulation effect.Therefore, existing technology also exists flameproof effect not
Good, structure is complicated, manufacture installation difficulty and high in cost of production problem.
Summary of the invention
It is an object of the invention to, it is provided that point fireproof landing door in a kind of elevator.It has good
Flameproof effect, simple in construction, manufacture be easy for installation and the feature of low cost.
Technical scheme: point fireproof landing door in a kind of elevator, including a layer door-plate, layer door
Plate includes the left-hand door plate on middle layered gate and right door-plate；Described left-hand door plate side is provided with side shield,
Side shield connects has door pocket flanging, left-hand door plate opposite side to be provided with the first notch cuttype step；The described right side
Door-plate side is provided with the second-order ladder type step coordinated with the first notch cuttype step mutual dislocation, right
Door-plate opposite side is provided with side shield, and side shield is connected with door pocket flanging；Described left-hand door plate and You Men
Plate upper end is equipped with upper cover, left-hand door plate and right door-plate lower end and is equipped with low head, left-hand door plate and
Right door-plate is provided with reinforcement；The cross section of described side shield is trapezium structure.
In aforesaid a kind of elevator in point fireproof landing door, it is equipped with in described left-hand door plate and right door-plate
Heat-barrier material, heat-barrier material is externally provided with cellophane, and cellophane is externally provided with and left-hand door plate and right door-plate
The fixed plate being connected.
In aforesaid a kind of elevator in point fireproof landing door, described first notch cuttype step and second-order
Heat-insulating and sealing circle it is equipped with on ladder type step.
Compared with prior art, the present invention is by arranging side on the left and right door-plate of middle layered gate
Baffle plate cooperates with door pocket flanging, forms a sealing surface, and is arranged to by side shield trapezoidal
Structure, can be with better seal on the premise of ensureing to connect, when layer door is at door-closing in-place
Time, side shield forms a labyrinth structure with door pocket, is so possible to prevent the fire outside hoistway
Flame rushes in hoistway by the gap between door pocket and door-plate；Meet mutually at left and right door-plate and phase is set
The the first notch cuttype step coordinated mutually and second-order ladder type step, become labyrinth shape when meeting sealing
Formula, can to the flame outside hoistway by gap between two door-plates time repeatedly stop,
Effectively slow down the speed that flame enters.In sum, the present invention have good flameproof effect,
Simple in construction, manufacture the easy for installation and feature of low cost.
Heat-barrier material asbestos are additionally set on the door-plate of layer door, because left and right door-plate is equipped with
Door panel flap, can well place asbestos, the most also lay cellophane outside heat-barrier material,
Heat-blocking action can not only be played, moreover it is possible to make heat-barrier material difficult drop-off, and solid by fixed plate
Fixed so that asbestos board is difficult to drop, and then play and delay the rising of temperature in hoistway, improve it
The effect of heat insulation effect.By arranging heat-insulating and sealing on the first and second notch cuttype steps
Circle, is possible not only to prevent flame from coming in from door gap, moreover it is possible to slow down between the door-plate of left and right
Mutually impact severity, extends the service life of door-plate.
