Abstract

The utility model relates to a fire-proof elevator door which is divided in the middle. The connection between the left and the right door of the elevator is of a ladder shape; the left and right door edges are overlapped; bending hooks are arranged on the door leaves and near the lintels; upward bending edges are arranged on the lintel near the door leaves; spaces h are arranged between the bending edges and the frames of the lintels; the bending hooks on the left and right door leaves are inserted into the spaces h; a bending part is arranged on the door leaves and near the upright posts; when the left and the right door leaves are closed, the sides of the upright posts near the door leaves are overlapped on the bending parts of the door leaves; a blocking board with a bending part is fixed under the left and the right door leaves and near the sill; and one edge of the blocking board is fixed under the door leaves, and the other edge is inserted into the flute of the sill. The opposed door leaves, upright posts, and sill are occluded with each other through special structure, to insulate the elevator with the outside when the doors are closed, thus a large gap due to metal distortion and expansion after being heated is avoided and the integer structure after being heated is kept to bear the corresponding stress.

Description

The middle fire prevention hoistway door that divides

One, technical field:

This novel hoistway door that uses in a kind of elevator that relates to, particularly a kind of hoistway door with fire-proof function.

Two, background technology:

The design of general hoistway door, all adopt such as Fig. 3---shown in Figure 7, slit in the middle of the door leaf of the left and right sides is to hold yielding position most as shown in Figure 3, Fig. 4 is door pillar and door leaf part schematic diagram, the slit of door pillar and door leaf is positioned at the both sides of whole Room door entrance, it is the place of slit maximum, and be the main load part of whole Room door, can Room door carry certain impact when catching fire, depend primarily on the restraining structure of door pillar and door leaf, Fig. 5 is the structure of lintel and door leaf part, and the slit of lintel and door leaf is positioned at the top of whole Room door entrance, and hot gas and flame are the easiest thus to vertical spread during fire, Fig. 6 is the part-structure figure of door leaf and sill, because the restriction of these structures makes it when running into fire, can not effectively prevent fires; This mainly be because: in fire, the hoistway door surface can be subjected to the high temperature more than 1000 ℃, and at high temperature, following situation can take place conventional lift Room door:

1, produces gross distortion, between two fan doors, form very big slit, cause injures and deaths so that personnel fall into hoistway in the escape easily.

2, Room door caves in or door leaf can not bear the power of regulation, so that personnel open Room door in the escape by mistake, falls into hoistway and causes injures and deaths.

3, produce gross distortion, lose closure, so that the condition of a fire of disaster-stricken floor spreads to other floors by hoistway from hoistway door.

Because more than, the hoistway door in the prior art can not satisfy the growing needs of society.

Three, summary of the invention:

This novel purpose is the hoistway door that a kind of energy of design satisfies the fire prevention needs, makes it when meeting fire, can effectively protect the safety in the elevator.

The following structure of this novel employing realizes above-mentioned purpose: divide the fire prevention hoistway door in a kind of, the door leaf joint, the left and right sides of Room door is stepped, and the left and right door limit at door leaf ladder place overlaps, be provided with crotch near the lintel place on the left and right sides door leaf of hoistway door, lintel is provided with upwards bending edge near the door leaf place, leave gap h between bending edge and the lintel framework, crotch near the lintel place on the door leaf of the left and right sides inserts among the h of gap, and can in the gap, move with door leaf, door leaf has a bending near the end of door pillar, and when left and right door is closed, on the door pillar near being bent with a section and overlapping on the side of door leaf and the door leaf, near the sill is fixed with the baffle plate of a band bending below the door leaf of the left and right sides, baffle plate is fixed on the below of door leaf on one side, the another side of baffle plate inserts in the groove of sill, and can be mobile with fan in groove, near the sill is fixed with the baffle plate of a band bending below door leaf, baffle plate is fixed on the below of door leaf on one side, the another side of baffle plate inserts in the groove of sill, and can be mobile with door leaf in groove.

This fire prevention Room door system belongs to elevator components; comprise the layer door gear of door leaf, door pillar and the motion of drive Room door etc.; just be that with common Room door system difference it can guarantee complete performance and the heat-proof quality of hoistway door system in fire, play the effect of protection personal safety.Its contour structures is simple, in the door system of the whole Room weak link be exactly between the door of the Room and Room door and side wall outer panel, lintel, sill between the gap.Under normal condition, Room door is closed the gap of back between these parts generally all about 5mm, is not more than 6mm.These parts just are easy to generate the said situation in front in the situation of being heated when fire takes place.So this is novel in the design process of fire protection gate, to between door leaf, side wall outer panel and the sill all by the mutual interlock of special structure, elevator door can well be hedged off from the outer world after cutting out, excessive and produce big slit with the back flow of metal that keeps from heat, and after being heated, can keep its integraty, can bear corresponding power.

Specific embodiment

This fire prevention Room door system belongs to elevator components, the layer door gear that comprises left and right sides door leaf, door pillar, lintel, sill and the motion of drive door leaf, be illustrated in figure 1 as hoistway door Facad structure figure, wherein 1 is left and right sides door leaf, 2 is the left and right door column, and 5 is lintel, and Fig. 2 is hoistway door structure figure, 6 is layer door gear, and 8 is sill.

Structure after the improvement is specific as follows:

One, the structure design between the door leaf of the left and right sides, coincident configurations as shown in Figure 7, this structure employing its adjacent regions when left and right sides door leaf 1 closure is designed to steplike-gate limit 12, and when making left and right sides door leaf 1 closure, the left and right door limit of ladder position overlaps.

Two, the structure design of side wall outer panel 2 and door leaf 1 as shown in Figure 8, the constitution diagram of side wall outer panel 2 and door leaf 1 point of attachment when this figure is door leaf 1 closure, side wall outer panel 2 is an occlusion structure with door leaf 1, bending shown in Figure 73 is made on door leaf limit near side wall outer panel 2 ends when door leaf 1 cuts out, when making door leaf 1 closure, bending 3 on the door leaf 1 can be inserted on the side 4 of side wall outer panel 2, when having avoided door leaf 1 to close and side wall outer panel 2 generation slits, and 16 is well enclosure.

Three, the structure design between lintel 5 and the door leaf 1, as shown in Figure 9, crotch 9 forms engaged have also been designed with lintel 5 on the top of door leaf 1, leave gap h between the upwards bending edge 10 of lintel 5 and the lintel framework 11, door leaf 1 top is shaped on crotch 9 near lintel 5 places, crotch 9 inserts making progress of lintel 5 and leaves among the h of gap between bending edge 10 and the lintel framework 11, and crotch 9 can unlatching and the closure with door leaf 1 move freely between the h of gap.

Four, the structure design between door leaf and the sill as shown in figure 10, this structure is below door leaf 1, near sill 14 places, be fixed with the baffle plate 13 of a band bending, baffle plate 13 is fixed on the below of door leaf 1 on one side, and the another side of baffle plate 13 inserts in the groove 15 of sill 14, and can be with the unlatching and closed the moving freely of door leaf 1 in groove 15, thereby guaranteed after the door leaf closure of the left and right sides leak tightness between door leaf 1 and the sill 14.
