An embedded landing door structure and its setting method

Abstract

The invention discloses an embedded landing door structure, comprising a hoistway frame corresponding to the elevator shaft, and a landing door frame arranged on the front of the hoistway frame for setting the elevator landing door; the hoistway frame includes hoistway columns, arranged on The hoistway ring beam between the hoistway columns; the landing door frame includes a frame beam for setting the elevator landing door, and a threshold assembly arranged on the frame beam corresponding to the elevator landing door; the landing door frame It partially or fully overlaps with the hoistway frame in the vertical direction. And a method for setting an embedded landing door structure. The present invention can make full use of the inner space of the elevator shaft and reduce the lateral setting depth of the shaft, so as to improve the utilization rate of the shaft and reduce the erection cost of the shaft frame.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an embedded landing door structure and a setting method thereof. Background technique [0002] At present, in the layout of the elevator shaft, the hall door sill of the single-door type elevator needs to protrude a certain distance toward the elevator shaft, and the hall door sill of the double-door type elevator needs to extend a greater distance; from the technical From a point of view, the distance from the hall door sill to the elevator shaft is positively correlated with the lateral depth of the elevator shaft. The larger the hall door sill protrudes, the greater the lateral depth of the elevator shaft. However, the horizontal depth setting value of the double-door type elevator shaft is usually a multiple of the lateral depth setting value of the single-door type elevator shaft. Low, and the erection cost of the hoistway frame is high. Contents of the inve...

The larger the hall door sill protrudes, the greater the lateral depth of the elevator shaft. However, the horizontal depth setting value of the double-door type elevator shaft is usually a multiple of the lateral depth setting value of the single-door type elevator shaft. Low cost, high construction cost of hoistway frame
