Abstract
The utility model discloses a fireproof elevator shaft door, which comprises door panels, a door jamb, a door head, a sill component and a forced closing device. Ladder-shaped steps which are mutually staggered and complemented are arranged at closed positions of a left door panel and a right door panel which are hung under the door head, a fireproof plate is arranged at connection positions of left, right and upper sides of the door panels and the door jamb, the fireproof plate is provided with folded edges, the door jamb is provided with grooves which are complemented with the folded edges of the fireproof plate to form a labyrinth structure, lower lateral edges of the door panels are provided with lower seal heads engaged with side grooves of the sill component, and the forced closing device is arranged at the backs of the door panels. The fireproof elevator shaft door is simple in structure, can effectively prevent fire and soot invading, needs small mounting space, and can effectively reduce mounting cost and meet fireproof requirements of elevator shaft doors.
Description
Technical field
The utility model relates to a kind of elevator door, especially relates to a kind of elevator fireprotection layer door with fire-proof function.
Background technology
At present, along with the continuous development of elevator industry and the raising of public security consciousness, requirement to the elevator door system is more and more higher, much all require the configuration fire protection gate, and in the market most of Fireproof door structure complexity, manufacture craft are loaded down with trivial details, and because its nudging device is arranged on the side of layer door, its installing space is bigger, therefore the cost of whole fireprotection layer door is higher, though the comparatively simple fire protection gate of some structures is also arranged, but fire proof construction is undesirable, is difficult to just really play flameproof effect.For example, a kind of on Chinese patent literature disclosed elevator fire-type layer door, its notification number is: CN 201169178Y, though be provided with sealing member at the closure place of door-plate and the coupling end of door-plate and door pocket, but its seal configuration is simple, can not effectively intercept the fire and the intrusion of flue dust, and the bottom of door-plate and sill junction there is not the effective seal structure yet, so its flameproof effect is unsatisfactory.
The utility model content
The utility model is in order to solve the problem that elevator landing door structure complexity, installing space are big and cost is high of prior art, and a kind of simple in structure, installing space is little, cost is low elevator fireprotection layer door is provided.
To achieve these goals, the utility model is by the following technical solutions: a kind of elevator fireprotection layer door, comprise door-plate, door pocket, door head, sill assembly and nudging device, be suspended under the head about the closure places of two fan door-plates be provided with mutual dislocation and complementary notch cuttype step, on door-plate, be provided with fire-proof plate with the left and right of door pocket and upside junction, fire-proof plate is provided with flanging, described door pocket is provided with and the complementary groove that becomes labyrinth structure of the flanging of fire-proof plate, is provided with the low head that cooperates with the chute of sill assembly at the lower side of door-plate.When accidents such as presence of fire, fire and flue dust are to invade by the junction of the closure place of two fan door-plates and door-plate and door pocket, two fan door-plates of elevator door of the present utility model are provided with mutual dislocation and complementary notch cuttype step at its closed place, junction at door-plate and door pocket is provided with fire-proof plate, can form mazy partition-type structures between fire-proof plate and the door pocket, the low head of the downside setting of door-plate then is positioned at the chute of sill assembly, therefore, around the whole door-plate and intermediate closed place all forms labyrinth type exclusion seal structure, thereby fire and flue dust are blocked in layer outdoors, to reach flameproof function.
As preferably, the cross-sectional plane of described fire-proof plate is L-shaped, and the groove cross section complementary with it is F shape on the door pocket, and both are coupled and form actv. labyrinth type partition-type structures, thereby helps guaranteeing the fire resistance of fireprotection layer door.
As preferably, the low head cross-sectional plane of being located at the door-plate lower side is T-shaped, can effectively seal, and helps the mobile guide of door-plate again.
As preferably, described nudging device is located at the behind of door-plate, thereby can obviously reduce installing space, reduces cost of installation.
As preferably, described door-plate is provided with reinforced rib behind, thereby effectively improves the intensity of door-plate; Steel plate or stainless steel sheet that described door-plate employing thickness is 1.2mm～2mm are made, and under the prerequisite that guarantees door-plate intensity, alleviate its weight as far as possible, cost-cutting, the door-plate that adopts corrosion-resistant steel to make not only has good anti-rust properties, improve its appearance simultaneously, promote its quality class.
In sum, the utlity model has following beneficial effect: (1) is located at around the door-plate and the labyrinth type exclusion seal structure at intermediate closed place, and is simple in structure, can effectively stop the intrusion of fire and flue dust; (2) required installing space is little, can reduce cost of installation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the cross sectional drawing of door-plate of the present utility model at closure state.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
At Fig. 1, among the embodiment shown in Figure 2, elevator fireprotection layer door of the present utility model includes 3, adopt sill assembly 4 that aluminum alloy makes and respectively with door 3 and sill assembly 4 bonded assembly door pockets 2, described door pocket 2 can be made into big narrow door jamb shape, to satisfy different needs, parts such as described 3 roller and steel rope all adopt refractory material to make, about two fan door-plates 1 be suspended in 3 time, lower side setting at door-plate 1 cooperates the T-shaped low head of cross-sectional plane 8 with the chute 41 of sill assembly 4, and about closure places in the middle of the two fan door-plates 1 mutual dislocation and complementary notch cuttype step 11 are set, on door-plate 1 with the left side of door pocket 2, the right side and upside junction are provided with the L-shaped fire-proof plate of cross-sectional plane 6, the relevant position is provided with and fire-proof plate 6 complementations on door pocket 2 simultaneously, its cross-sectional plane is the groove 7 of F shape, in addition, for reduce installation dimension as far as possible, nudging device 5 is arranged on the back side of door-plate 1, it is moved with door-plate 1, reduce installing space, reduced civil engineering cost; Simultaneously, for gaining in strength, by welding or bonding way reinforced rib 9 is set at the back side of door-plate 1.In addition, the steel plate that door-plate 1 adopts thickness to carry out spray treatment for the 1.5mm surface is made, and certainly, door-plate 1 also can adopt the stainless steel sheet of PROCESS FOR TREATMENT such as etching, minute surface to make.
Because two fan door-plates 1 of elevator door of the present utility model are at its closed place and be equipped with mazy exclusion seal structure with door pocket 2 and sill assembly 4 junctions all around, therefore when accidents such as presence of fire, above-mentioned fireprotection layer door can be blocked in layer outdoors with fire and flue dust, thereby reaches flameproof requirement.
