Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention particularly relates to an elevator installation method and an installation work floor device for a home elevator installed in a single-family private residence.

[Prior Art] Conventionally, as an installation method for this type of elevator, for example, Japanese Patent Application Laid-Open No. 60-52483 and Japanese Patent Application Laid-Open No. 63-134 have been proposed.
There is something described in Publication No. 487, which first of all,
Assemble a work floor on the top floor of the hoistway, use this work floor to attach the permanent pulley base and temporary pulley to the top of the hoistway, then install the permanent hoist, and install the permanent hoist on the hoist. The procedure is to hang a rope, drive the hoisting machine, and erect the guide rail.

In addition, conventionally, as a work floor device for hemming elevators,
For example, Japanese Patent Publication No. 51-38975 and Japanese Patent Application Publication No. 60
There is one disclosed in Japanese Patent No. 19862, which has a structure in which it is mounted using the floor of the landing and the wall of the hoistway as fulcrums, so that the load is applied to the floor of the landing and the wall of the hoistway.

Furthermore, since the elevator scaffolding device disclosed in Japanese Utility Model Publication No. 62-23954 is a scaffolding device that is attached to a guide rail, no load is applied to the landing floor or the walls of the hoistway.

``Problems to be Solved by the Invention'' In the conventional elevator installation method described above, the work floor assembled at the top of the hoistway is attached using the landing floor and the wall of the hoistway as fulcrums. Loads are applied to the floor of the landing and the walls of the hoistway.However, there are three types of building structures for single-family homes in which home elevators are installed: steel, wood, and concrete. Although it is possible to install a conventional work floor on the hoistway,
Steel-framed houses and wooden houses, which make up the majority of private residences,
Elevator landing floors are generally made of plywood as the base, and the inner walls of the hoistway are made of board or plywood.It is not possible to apply a load to the landing floor and the walls of the hoistway, so the conventional work floors mentioned above are not used. Can not do it.

In addition, the power source of the winding drum type hoist for permanent installation is 200V, but at the construction site of a private residence, a 200V power source is not required except for elevator installation work, so a temporary 200V power source is installed at the site. It is rarely prepared. Therefore, the elevator contractor has to separately draw a temporary power source for elevator installation work, which poses problems in terms of economy and efficiency.

Next, the conventional work floor devices for elevator installation shown in the above-mentioned Japanese Patent Publication No. 51-38975 and Japanese Patent Application Laid-open No. 60-19862, etc., are difficult to use because the load is applied to the floor of the landing and the wall of the hoistway. For the same reason as above, it cannot be used in steel-framed houses or wooden houses, and since handrails and baseboards are not provided, there is a problem with safety during elevator installation work.

In addition, the work floor device shown in Publication of Utility Model Publication No. 62-23954 does not apply any load to the landing floor or the wall of the hoistway, but the guide rail to which this scaffold device is attached is a guide rail applied to the elevator of -a. , located near the center of the hoistway. Therefore, scaffolding equipment cannot be installed from the landing side.

Furthermore, the scaffolding device is fixed to the guide rail with a rail clip, making installation work complicated. Furthermore, since the structure is such that the scaffolding equipment is assembled sequentially from the bottom of the hoistway, a large number of stages of scaffolding are required, the number of parts increases, and the assembly is complicated, resulting in increased installation costs. There were also safety issues such as accidents involving falls from scaffolding equipment.

Furthermore, as conventional work floor equipment for installing elevators other than those described in the above publications, there are bidet scaffolds, single pipe scaffolds, etc. that are erected on bits in the hoistway. The area of the road is small, and a winding drum-type hoist is installed on the bit of the hoistway, which not only makes it difficult to install the hoist, but also makes assembly complicated and economically problematic. was there.

This invention was made to solve the above-mentioned problems, and the first invention is that even if the I'iII structure of the landing is steel or wooden, the elevator can be easily installed and the work is easy. The purpose of the present invention is to provide an elevator installation method that allows the floor to be easily moved to any floor and that can be safely installed using a 100V power source.

In addition, the second invention can be easily installed from the landing side without applying any load to the floor of the building or the walls of the hoistway, and can be used even if the building is made of steel or wood, making it economical and safe. The object of the present invention is to obtain a work floor device for installing an elevator with excellent performance.

[Means for solving the problem] The elevator installation method according to the first invention of the present invention is as follows:
