TW202231565A - Elevator door with heat-insulating structure including at least two door bodies, each of which includes a first door panel, a second door panel and an insulator - Google Patents

Abstract

An elevator door with a heat-insulating structure has at least two door bodies, each of which includes a first door panel, a second door panel and an insulator. The insulator has a frame to fix a heat-insulating panel and configured to arrange the insulator between the first door panel and the second door panel. In addition, a barrier layer is coated on the insulator. By disposing the insulator and the barrier layer, the heating time of the elevator is delayed, thereby improving safety and having more time to escape.

Description

Elevator doors with thermal insulation

The present invention relates to the technical field of elevator doors, in particular to an elevator door with a thermal insulation structure.

Many elevators have been equipped with a smoke and fireproof structure in the design of the elevator door to prevent smoke from entering the elevator workshop or entering the elevator through the elevator door panel when a building fire occurs. The elevator door structure with smoke and fire resistance can prolong the time for the flame and smoke to spread from the outside of the elevator to the inside of the elevator.

However, in the fire scene, in addition to avoiding the inhalation of thick smoke, the high temperature of the fire scene is often the cause of the trapping. When encountering the high temperature of the fire, the elevator is also easy to get out of control or even deform and get stuck, causing personal injury.

Based on the above deficiencies, the purpose of the present invention is to provide an elevator door structure, especially an elevator door structure capable of effective heat insulation, so as to delay the time for the temperature rise in the elevator.

Based on the above object, the present invention provides an elevator door with a thermal insulation structure, which has at least two door bodies, each of the door bodies includes a first door panel, a second door panel and an insulator, wherein the insulator is disposed on the Between the first door panel and the second door panel, the heat insulator includes a frame for fixing a heat insulating panel, and the heat insulating panel is made of magnesium carbonate.

The first door panel has two side walls extending toward one side and defines an accommodating space, the second door panel is substantially U-shaped with two side walls and a bottom wall forming a accommodating portion, and the heat insulator is disposed in the accommodating portion , the two side walls of the second door panel are disposed in the accommodating space toward the bottom wall of the first door panel.

Preferably, a barrier layer is sandwiched between the first door panel and the second door panel, and a barrier layer is coated on the periphery of the insulator, and the barrier layer is gypsum board. There is no direct contact between the door panel and the second door panel and between the second door panel and the insulator.

Preferably, the second door panel and the first door panel have a plurality of corresponding positioning holes, and the positioning holes are used as welding points for welding the second door panel and the first door panel during installation.

In order to clearly illustrate the specific embodiments, structures and effects of the present invention, the following descriptions are given in conjunction with the drawings:

Please refer to FIG. 1 , which shows an elevator door with a thermal insulation structure, which has at least two door bodies 10 , each of the door bodies 10 includes a first door panel 11 , a second door panel 13 and an insulator 15 . The body 15 is disposed between the first door panel 11 and the second door panel 13, wherein the heat insulating body 15 includes a frame body 151 for fixing a heat insulating panel 152, and the heat insulating panel 152 is made of magnesium carbonate material , Magnesium carbonate has the characteristics of high temperature resistance, the setting of the heat insulation plate 152 can block high temperature and delay the heating time inside the elevator.

The first door panel 11 has two side walls extending toward the same side and defines an accommodating space 115. One of the side walls of the first door panel 11 has a curved structure, which is used as an engaging structure for the door body of the elevator door; the second door panel 13 is roughly U-shaped, and has a bottom wall and two side walls to form an accommodating portion 135 together. A bottom wall is further disposed in the accommodating space 115 , so that the first door panel 11 and the second door panel 13 sandwich the heat insulator 15 .

The first door panel 11 and the second door panel 13 both have a plurality of corresponding positioning holes 111 and 131 . The positioning holes 111 and 131 are used as welding points for welding the first door panel 11 and the second door panel 13 during installation.

In this embodiment, a barrier body 15 is disposed between the first door panel 11 and the second door panel 13 , and a barrier layer 17 is covered on the heat insulating body 15 , and the barrier layer 17 has a 600-degree flame resistance. The first door panel 11 and the second door panel 13 are bonded with a special adhesive material, or the heat insulator 15 is bonded with a 600-degree flame-resistant adhesive material. The barrier layer 17 is gypsum board, and the gypsum board has fire resistance and high temperature resistance, the barrier layer 17 is provided so that the first door panel 11 and the second door panel 13, or the first door panel 11 or the second door panel 13 and the insulator 15 will not be in direct contact, which can extend at least One hour heating time.

In addition, in the present invention, smoke-proof rubber strips can be arranged on the edges of the first door panel 11 and the second door panel 13 to prevent the smoke from entering the elevator interior.

In the present invention, the insulating body 15 and the barrier layer 17 are arranged between the door panels, and the high temperature resistance of the magnesium carbonate board and the gypsum board is used. Even if the elevator is unfortunately trapped in the fire, the elevator door structure of the present invention can effectively Block the high temperature, delay the heating time of the elevator, improve the safety and effectively improve the escape time.
