Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a fireproof elevator landing door. Background Art

[0002] With the implementation of the new housing and construction regulations, it has become a necessary requirement for elevators to meet the fire resistance requirements of GB / T27903, making the design requirements for fire doors and meeting mass production requirements also important.

[0003] The fire protection design of existing elevator hall doors requires manual installation of door sealing panels at a later stage, which is a cumbersome process and difficult to achieve fully automatic mass production.

[0004] It is of great significance to design an elevator hall door that meets the fire resistance performance of GB / T27903 standard (E≥120min) and has relatively higher production efficiency and product quality. Utility Model Content

[0005] The purpose of the utility model is to provide a fireproof elevator landing door. The utility model has the characteristics of high production efficiency.

[0006] The technical solution of the utility model: a fireproof elevator landing door comprises a door panel and a plurality of reinforcing ribs arranged on the door panel; the door panel comprises a left door panel and a right door panel; curved and staggered labyrinth pieces are respectively arranged between the left door panel and the right door panel, and the labyrinth pieces are assembled to form a curved and staggered labyrinth structure.

[0007] In the aforementioned fireproof elevator landing door, the door panel and the reinforcing ribs are connected by high-strength riveting or welding technology.

[0008] In the aforementioned fireproof elevator landing door, the door panel is prepared by a sheet metal one-piece molding process.

[0009] In the aforementioned fireproof elevator landing door, the door panels are provided with upper guard plates and side guard plates respectively; the upper guard plates and side guard plates are formed by integrally bending corresponding parts of the door panels.

[0010] In the aforementioned fireproof elevator landing door, a fire-resistant sealing strip is provided on the edge of the door panel.

[0011] Compared with the prior art, the utility model sets a labyrinth piece between the left door panel and the right door panel to form a labyrinth structure. The labyrinth structure adopts a plate forming design, and a complex passage is formed by staggered plates, which effectively prevents the spread of fire and smoke, enhances fire resistance, and meets the fire resistance requirements of GB / T27903 standard. The fire resistance integrity performance (E) is greater than or equal to 120 minutes;

[0012] The door panel is designed to adapt to the one-piece molding process of the sheet metal processing center. This design solves the problem that ordinary fire door designs require manual later installation of door sealing panels, realizes fully automatic mass production, and improves production efficiency and product consistency.

[0013] In summary, the utility model has the characteristic of high production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0023] Example. Fireproof elevator landing door, such as Figure 1-7 As shown, it includes a door panel 1 and a plurality of reinforcing ribs 2 arranged on the door panel 1; the door panel 1 includes a left door panel 11 and a right door panel 12; curved and staggered labyrinth pieces are respectively arranged between the left door panel 11 and the right door panel 12, and the labyrinth pieces are assembled to form a curved and staggered labyrinth structure 3, and the labyrinth structure 3 effectively prevents the spread of fire and smoke and enhances the fire resistance.

[0024] The door panel 1 and the reinforcing rib 2 are connected by high-strength riveting or welding technology.

[0025] The door panel 1 is manufactured by using a sheet metal integral molding process.

[0026] The door panel 1 is formed or bent from a cold-rolled steel plate through cold working.

[0027] The door panel 1 is provided with an upper guard plate 42 and a side guard plate 41 respectively; the upper guard plate 42 and the side guard plate 41 are formed by integrally bending corresponding parts of the door panel 1.

[0028] The edge of the door panel 1 is provided with a fire-resistant sealing strip to ensure that smoke and flames can be effectively prevented from entering when a fire occurs, thereby improving the fire resistance.

[0029] The door panel 1 is installed in a modular design, which is convenient for quick installation and replacement on site, and improves construction efficiency and maintenance convenience.
