2. Description of the Related Art Openings are formed on the hoistway walls of elevators so as to reach entrances on each floor and serve as entrances. A three-way frame, a landing door, and the like are installed near these openings. At a recent elevator installation site, a landing doorway unit formed by integrally assembling a door pocket portion, a three-sided frame, a landing sill, a landing door, and the like and temporarily fixing it in a predetermined positional relationship with a reinforcing member is provided at the opening of the opening. By temporarily holding the plurality of landing members on the hoistway side, it is possible to efficiently carry out the work of transporting and mounting the plurality of landing members, and eliminate the need to separately cure the openings, thereby improving the installation efficiency. It is becoming general.

[0003] In order to temporarily hold the landing doorway unit in this way, for example, a technique has been conventionally known in which a temporary holding member such as a bracket is fastened and fixed to a landing floor or a hoistway wall using fasteners such as anchor bolts. However, installation and removal of fasteners such as anchor bolts are complicated,
Elevator installation efficiency could not be significantly improved.

Therefore, as disclosed in Japanese Patent Application Laid-Open No. Hei 4-251090, a pair of upper and lower supports are arranged on the landing side so as to cross the opening, and these supports and the door pocket portion are provided. And a temporary holding device that connects a landing sill with a wire rope have been proposed. In this conventional temporary holding device, the hoistway wall around the opening is sandwiched between the pair of upper and lower supports disposed on the landing side and the landing entrance unit on the hoistway side by tightening the wire rope. In this state, the landing doorway unit can be held.

[0005]

In the above-mentioned provisional holding device which has been conventionally proposed, a large tension is required for the wire rope to support the weight of the landing doorway unit. Therefore, the wire rope is strongly tightened. The landing doorway unit must be pressed against the hoistway wall, but if such a strong force is used to press the landing doorway unit against the hoistway wall, the landing doorway unit may be deformed due to locally excessive pressing force. was there. Further, in such a conventional temporary holding device, since the upper support is arranged at an arbitrary height, the support is hung with a wire rope between the support and the landing entrance unit. Until then, it has to be in an unstable state in which it can move freely, and therefore, there has been a problem that it is not easy to hang and tighten the wire rope on the support.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems of the prior art, and has as its object to provide an elevator landing that can easily and surely temporarily hold a landing entrance / exit unit at a desired position without deformation. An object of the present invention is to provide a temporary holding device for an entrance unit.
