Heat-resisting fireproof elevator door

Abstract

The invention discloses a heat-resisting fireproof elevator door. The heat-resisting fireproof elevator door comprises a pair of first door boards, a pair of second door boards, a pair of third door boards and supporting boards, wherein the second door boards are partially overlapped outside the first door boards respectively; first fireproof pieces are arranged between the first door boards and the second door boards; the third door boards are partially overlapped outside the second door boards respectively; second fireproof pieces are arranged between the second door boards and the third door boards; the supporting boards are fixed to walls; third fireproof pieces are arranged between the supporting boards and the third door boards. The fireproof pieces are arranged between the door boards, so that flames are effectively prevented from entering an elevator rail car through gaps between the door boards, dense smoke and the flames are prevented from spreading to other floors through an elevator, and safety of the elevator door is increased; when a fire happens, the resident escape time is prolonged, and the personal and property losses of residents are reduced.

Description

technical field [0001] The invention relates to an elevator door. Background technique [0002] With the development of modernization, elevators have become an indispensable means of transportation in high-rise buildings. In order to facilitate people to take elevators, most elevators are installed in the center of the building. Therefore, in the event of a fire, thick smoke will pass through the elevator. The pipes spread to all floors, shortening the escape time of personnel and seriously endangering the safety of residents' lives and property. [0003] Therefore those skilled in the art are committed to developing a kind of elevator door that prevents heavy smoke from spreading to each floor through the elevator door. Contents of the invention [0004] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide an elevator door that prevents dense smoke from spreading to each floor through the eleva...
