Abstract

The invention relates to an elevator bypass type fireproof door. The elevator bypass type fireproof door comprises a shutter door sheet, a slow door sheet and a fireproof assembly, wherein the shutterdoor sheet and the slow door sheet are arranged in parallel; the fireproof assembly comprises a fireproof baffle plate, a limiting piece and a tensioning piece; the middle of the fireproof baffle plate is pivoted to the end of the shutter door sheet through a pivoting piece; the limiting piece is fixed on a sill of one side of the shutter door sheet, and is positioned between the shutter door sheet and the fireproof baffle plate, the limiting piece is used for limiting the tail end of the fireproof baffle plate; and the two ends of the tensioning piece are fixed on the shutter door sheet andthe fireproof baffle plate correspondingly, and the tensioning piece is located between the pivoting piece and the limiting piece. The elevator bypass type fireproof door has the advantages of beinggood in fireproof effect, compact in structure, low in cost, and high in universality.

Description

technical field [0001] The invention relates to the field of elevator equipment, in particular to an elevator side-opening fireproof landing door. Background technique [0002] With the frequent occurrence of elevator accidents, the society pays more and more attention to the accident protection of elevators. In order to deal with the unexpected situation of fire in the building, it is usually necessary to install landing doors with fireproof functions. [0003] In the existing side-opening type landing door, between the shutter door panel and the slow door panel, the door seam sealing structure is a fixed right-angle shape. Compared with ordinary side-opening landing doors, since the fire-proof landing doors must meet the performance requirements of the national standard for integrity and heat insulation, the side-opening landing doors need to increase the front and rear gaps of the door panels to install right-angled overlapping doors. sew bezel. The space occupied by th...
