Abstract

PROBLEM TO BE SOLVED: To solve problems in the repairing work of adding a smoke shielding function that, for blocking clearance between the side end of a door stop post of the jamb of a landing door and a door stop post of the jamb, a smoke shielding member should be protruded from the side end of the door stop post of the jamb of the landing door, and when a protrusion amount is large, the smoke shielding member is largely protruded from the side end of the door stop post of the jamb of the landing door when fully opening the door, thus causing the necessity of exchanging the jamb and an increase in repairing cost when clearance between the side end of the door stop post of the jamb of the landing door and the door stop post of the jamb is wide.SOLUTION: A door stop post of the jamb includes existing door stop cushion rubber, and a through-hole having a fixing member for fixing the door stop cushion rubber on a rear face. After removing the existing door stop cushion rubber from the fixing member, the door stop metal is screwed to the fixing member using the fixing member.

Description

The present invention is provided in a single-opening type elevator landing door device, and when the all doors are closed, the smoke shielding device of the elevator landing device for shielding a gap between the landing door and the door-to-column pillar of the three-way frame, and the three-way frame It is about repair method of door-to-door pillar.

In a conventional elevator single door type landing door device, a landing doorway is opened and closed by a landing door having at least one door. For example, a landing doorway is opened and closed by a landing door having two doors, a high-speed door and a low-speed door.
