Abstract
The utility model discloses a fireproof landing door, which comprises a left door panel, a right door panel and a door jamb. Two or more steps are arranged on the lateral sides of the left door panel and the right door panel and are staggered to complement to each other when the left door panel and the right door panel are closed. Door panel edgefolds and door jamb edgefolds in match are arranged on the lateral sides of the door panels and the door jamb, and reinforcing ribs are arranged on the back of the door panels. Since the two or more steps are arranged on the lateral sides of the left door panel and the right door panel and are staggered to complement to each other when the left door panel and the right door panel are closed, intrusion of fire and smoke can be effectively prevented. Furthermore, the fireproof landing door is simple in structure and low in cost.
Description
Technical field
The utility model relates to a kind of elevator door, especially relates to a kind of fireprotection layer door.
Background technology
At present, along with the raising of the continuous development of elevator industry and public security consciousness, to the elevator door system require increasingly high; Much all require the configuration fire protection gate, for example, existing elevator door is provided with the fireproof component of the end face that is clamped in door opening; Thereby under the situation that contingency is caught fire; Even door and doorframe are owing to its heat expansion is out of shape, gap or seam between doorframe each end face relevant with door opening remain osed top, thereby can realize preventing fires.
And for example; Number of patent application is that the Chinese patent of CN200820031396 has disclosed a kind of elevator fire-type layer door; This elevator fire-type layer door comprises door-plate and door pocket; Described door-plate has mutual bonded assembly double-layer steel plate structure, and the coupling end of the closure place of described door-plate and door-plate, described door-plate and door pocket is provided with sealing member, thereby can realize certain anti-fire action.Yet above-mentioned existing Fireproof door structure is complicated, manufacture craft is loaded down with trivial details, and the cost of whole fireprotection layer door is higher, though the comparatively simple fire protection gate of some structures is also arranged, fire proof construction is undesirable, is difficult to just really play flameproof effect.
The utility model content
The utility model is to provide a kind of simple in structure to the defective that the above-mentioned background technology exists, and cost is low, can effectively prevent the fireprotection layer door of the intrusion of fire and smoke stratification.
For realizing above-mentioned purpose; The utility model discloses a kind of fireprotection layer door, two fan door-plate and door pockets about it comprises, said about the place, side of two fan door-plates be provided with two or more notch cuttype steps; When two fan door-plates were closed about said, said notch cuttype step mutual dislocation was complementary.The side of said door-plate and door pocket is provided with door panel flap and the door pocket flanging that cooperatively interacts, and said door-plate is provided with reinforced rib behind.
Further, said about two fan door-plates when closed, complementary between said door panel flap and the door pocket flanging, and form the slit of labyrinth structure.
Further, said door-plate is bondd each other by the different steel plate of thickness and constitutes.
Further, also fix between the steel plate of said door-plate with rivet or electric welding.
Further, said door-plate employing thickness is that steel plate, the stainless steel sheet of 1.2mm～2mm or the steel plate that sprays paint are processed.
In sum; The utility model fireprotection layer door is provided with two or more notch cuttype steps through the place, side of two fan door-plates about said, said about two fan door-plates when closed, said notch cuttype step mutual dislocation is complementary; Thereby can effectively prevent the intrusion of fire and smoke stratification; In addition, it is simple in structure, and cost is low.
Description of drawings
Fig. 1 is the structural representation of the cross-sectional plane of a kind of embodiment of the utility model.
The specific embodiment
For further understanding characteristic, technological means and the specific purposes that reached, the function of the utility model, the utility model is described in further detail below in conjunction with the accompanying drawing and the specific embodiment.
See also Fig. 1; Two fan door-plate 1 and door pockets 2 about the utility model fireprotection layer door comprises; The side place of two fan door-plates 1 is provided with two or more notch cuttype steps 11 about said, said about two fan door-plates 1 when closed, said notch cuttype step 11 mutual dislocation are complementary.Said door-plate 1 is provided with door panel flap 12 and the door pocket flanging 21 that cooperatively interacts with the side of door pocket 2; When two fan door-plates 1 are closed about said; Complementary between said door panel flap 12 and the door pocket flanging 21, and form the slit of labyrinth structure, thereby can effectively prevent the intrusion of fire and smoke stratification.
It is that steel plate, the stainless steel sheet of 1.2mm～2mm or the steel plate that sprays paint are processed that said door-plate 1 adopts thickness.In the present embodiment, said door-plate 1 is bondd each other by the different steel plate of thickness and constitutes, and in addition, also fixes with rivet between the said steel plate.Said door-plate 1 is provided with reinforced rib behind, thereby can guarantee that it is firm in structure, reliable.
In sum; The utility model fireprotection layer door is provided with two or more notch cuttype steps 11 through the place, side of two fan door-plates 1 about said, said about two fan door-plates 1 when closed, said notch cuttype step 11 mutual dislocation are complementary; Thereby can effectively prevent the intrusion of fire and smoke stratification; In addition, it is simple in structure, and cost is low.
The above embodiment has only expressed a kind of embodiment of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with accompanying claims.
