Description

An embodiment of the present invention relates to a three-sided frame closing plate installation member, a closing plate installation structure, and a closing plate installation method.

An opening will be provided at each floor of the building where the elevator will be installed. This opening has a pair of vertical frames and a horizontal frame connected to the upper ends of the pair of vertical frames, and a three-sided frame for attaching a landing door is installed.

Elevator hoistways are cavities that penetrate the building vertically, and if a fire breaks out on one floor, the fire can spread through the hoistway to other floors. In order to prevent the spread of fire, a closing plate is installed to close the gap between the three-sided frame and the opening. Since there is a large gap between the three-sided frame and the opening depending on the skeleton and the floor, and the error is large, a steel plate or the like is welded as a closing plate and installed at the site.

However, the welding work requires a welding machine, which requires a large amount of work and increases the setup time. In addition, since welding work requires experience, only skilled workers can perform the work. Further, there are restrictions on the work such that the product cannot be removed during maintenance work.

Conventionally, as a so-called welding-less work, there is a method of using bolt fixing instead of welding.

Japanese Unexamined Patent Publication No. 2008-21408

However, in the method of using bolt fixing instead of welding, it is necessary to secure a tool space for bolt fixing. For this reason, depending on the property, the gap between the opening of the building and the three-sided frame may be narrow, making it difficult to handle tools. In addition, since the bolts must be turned at each location, the work time cannot be shortened so much as compared with welding when the number of fastening points increases. Furthermore, there is a problem that it is not possible to adjust and install on-site because the connection between the opening and the three-sided frame changes for each floor.

The present invention eliminates the need for welding and tools, shortens the installation time, and allows the installation work to be easily performed according to the connection with the opening. It is intended to provide a method.

In order to achieve the above object, an aspect of the present invention is in a three-sided frame of an elevator which is installed in an opening of an elevator landing and has a pair of vertical frames and a horizontal frame connected to the upper ends of the pair of vertical frames.
