Description

Boarding door smoke shield device and its mounting method, and elevator boarding device and its installation method

The present invention relates to a technology for adding a smoke shielding function to a three-way frame constituting a landing in a landing door of an elevator.

When adding a smoke-shielding function to a landing door, a side receiving plate is formed on the three-side frame by machining a hole in the three-side frame and abutting an elastic member provided on the side of the door (for example, a patent) Reference 1 and Patent Reference 2).

Japanese Patent No. 5733574 JP 2008-265902 A

When machining holes in the three-way frame, it is necessary to mark the hole position using the side receiving plate as a guide while pressing the side receiving plate against the three-sided frame to match the hole position with the side receiving plate. . However, since the side receiving plate is elongated and flexible, it is necessary to perform marking while supporting the upper and lower portions of the side receiving plate, and it is difficult to determine the position of the side receiving plate and attach it alone.

Although the attachment method in Patent Document 1 is to fix the side receiving plate with a magnet and process the hole, the magnet may not be used depending on the material of the three-way frame. In addition, the doorway device in Patent Document 2 is provided with a long hole in a three-way frame vertical frame, and a stud bolt fixed to the receiving plate is inserted and fixed with a nut from the back of the vertical frame. If the work space for fastening the nut is not provided on the back of the three-way frame, the operation cannot be performed.

The present invention has been made in order to solve the above-described problems, and a landing door smoke shielding device and a mounting method for the landing door smoke shielding device capable of easily positioning a side receiving plate by one person. The purpose is to obtain.

The present invention provides an upper receiving plate attached to an upper frame constituting a three-way frame of a landing, a pair of side receiving plates attached to respective vertical frames constituting the three-way frame of the landing, and a landing door. When the door is fully closed, the upper portion of the landing door smoke shielding device includes a plurality of closing members that contact the upper receiving plate and the side receiving plates to close the gap between the landing door and the three-way frame. The receiving plate has engaged portions at both ends in the longitudinal direction, each side receiving plate has an engaging portion that engages with the engaged portion at one end, and each engaging portion has an engaging portion. The present invention relates to a landing door smoke shielding device in which each side receiving plate is fixed to an upper receiving plate by engaging the portions.

According to the landing door smoke-shielding device according to the present invention, the engagement portion provided on each side receiving plate is engaged with the engaged portion provided on the upper receiving plate, so that one person can easily side. The receiving plate can be positioned and fixed, and the landing door smoke shielding device can be efficiently attached.
