Anti-smoke and fireproof elevator door structure

The present invention discloses an elevator door structure, and more particularly relates to a smoke-proof and fire-proof elevator door structure.

In today's society, fire safety is receiving more and more attention. In particular, for multi-floor buildings with elevators, after a fire, smoke and fire that exist in the fire (ie floor) of the fire often penetrate the smoke. The gap of the fire-fighting elevator door is based on the chimney effect, and will quickly spread to other floors along the elevator shaft, which will increase the damage degree of the fire, which will lead to more loss of life and property.

More specifically, since the elevator door must be opened and closed frequently, there is a gap between the door panel and the door frame of the elevator door, and there is a gap. Similarly, different door panels are inevitably present. Gap, if the elevator door does not have a structure that prevents smoke and fire from diffusing from the ride to the ladder through the gap, after the fire, the smoke or fire existing in the pass can be diffused to the ladder through the gap.

In order to avoid the above situation, there is a need for a ride door structure that can take care of both smoke and fire prevention functions, which can prevent smoke and fire from spreading between different floors.

One of the aims of this creation is to make the elevator door structure have the functions of smoke prevention and fire prevention, thereby improving the fire safety of multi-floor buildings.

In order to achieve the above purposes and other purposes, the present invention provides a smoke-proof and fire-resistant elevator door structure for preventing smoke and fire from diffusing from a ride to a ladder well. The elevator gate structure includes a door frame and two Door panel.

The door frame includes a top frame, two side frames and a pedal. The tops of the side frames are respectively connected to the left and right ends of the top frame, and the pedals are connected to the bottoms of the side frames. The side frame and the pedal define a gate shaped space.

The door panels are disposed on the multi-directional field and open and close with each other in the same plane. When closed, the door panels obscure the gate-shaped space of the door frame. The door panels respectively include: a first fireproof panel, a first smokeproof strip, a second fireproof panel, a second smokeproof strip, a third fireproof panel, a third smokeproof strip, and a fourth fireproof panel. And a fourth smoke prevention strip.

The first fireproof board is fixed to the top of each of the door panels and extends toward the top frame to form a first bending passage with the top frame, so that fire cannot be diffused from the ride through the first bending passage to the Stairwell. The first smoke preventing strip is disposed at the top of each of the door panels to seal a gap between the top frame and the door panel.

The second fireproof board is fixed to the bottom of each of the door panels and extends toward the pedal to form a second bending passage with the pedal, so that fire cannot be diffused from the passenger field to the ladder shaft through the second bending passage . The second smoke prevention strip is disposed at the bottom of each of the door panels to seal a gap between the pedal and the door panel.

The third fireproof board is fixed to a side of each of the door panels adjacent to the side frames, and is adhered to the first fireproof board and extends toward the side frame to form a third bending passage with the side frame, so that Fire cannot be diffused from the ride to the ladder via the third bend channel. The third smoke preventing strip is disposed on a side of each of the door panels adjacent to the side frames to seal a gap between the side frame and the door panel.

The fourth fireproof board is fixed to a side of each of the door panels near the other door panel. The fourth smoke prevention strip is disposed on a side of each of the door panels adjacent to the other door panel. Wherein, the gap between the first fireproof panels is The gap between the door panels is staggered, the gap between the second fireproof panels is offset from the gap between the door panels, and the gap between the fourth fireproof panels is offset from the gap between the door panels. Waiting for the fourth fireproof board to form a fourth bending passage with the door panels, so that fire cannot be diffused from the passenger field to the ladder well through the fourth bending passage, and the fourth smokeproof strip seals between the door panels The gap.

In an embodiment of the present invention, at least one of the first bending channel, the third bending channel, and the fourth bending channel of each of the door panels is an S-shaped channel.

In an embodiment of the present invention, the heat resistance temperatures of the first smoke prevention strips, the second smoke prevention strips, the third smoke prevention strips, and the fourth smoke prevention strips are all at least 200 ° C.

In an embodiment of the present invention, the first smoke prevention strips, the second smoke prevention strips, the third smoke prevention strips, and the fourth smoke prevention strips are all non-self-igniting strips.

In an embodiment of the present invention, at least one of the first smoke prevention strip and the third smoke prevention strip of each of the door panels are disposed toward the direction of the field.

In an embodiment of the present creation, the second smoky strips are disposed toward the pedal direction.

In an embodiment of the present creation, the fourth smoke prevention strips are disposed toward each other.

In an embodiment of the present invention, the first fireproof panels, the second fireproof panels, the third fireproof panels, and the fourth fireproof panels are all stainless steel panels.

Therefore, after the fire, the smoke-proof and fire-proof elevator door structure of the present invention can first prevent the smoke from diffusing from the ride to the ladder through the gaps if the smoke temperature continues to rise. High, so that the smoke strips are burned, and the bending passage formed by the fireproof panels and the door frame can prevent the fire from diffusing from the ride to the ladder through the gaps.
