Abstract

A landing doorway device for an elevator, in which a tubular vertical frame provided at a side of a landing doorway has a landing doorway facing section facing the landing doorway and also has a hoistway facing section facing the inside of a hoistway. The hoistway facing section is provided with a vertical-frame heat insulation material for suppressing transfer of heat, transferred from the landing doorway facing section to the hoistway facing section, into the hoistway.

Description

technical field [0001] The present invention relates to an elevator hall entrance and exit device, and in particular to the improvement of the heat resistance of the elevator hall entrance and exit device. Background technique [0002] In a conventional hall door device for an elevator, a heat insulating member is attached to the surface of the door panel on the hoistway side (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese PCT Publication No. 2002-514701 [0004] However, in the existing elevators, not only the door panel but also the landing door casing faces the landing and the shaft, so when the landing door casing is heated due to a fire, the landing door casing reaches a high temperature, and there are equipment in the shaft Potential of fire due to the heat. Contents of the invention [0005] The present invention was made in order to solve the above-mentioned problems, and an object of the present invention is to obtain a hall entra...
