Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a scaffold for elevator installation work.

[Conventional technology]

A typical conventional scaffold for elevator installation work is a fixed scaffold in which scaffolding boards are stretched over scaffolding materials such as steel pipes or wood that are set up in a cross-shaped structure along the entire length of the hoistway. Then, workers stand on the scaffolding board and install guide rails, hoistway equipment, piping, wiring, and connections. Next, they assemble elevator cars and counterweights, and hang wire ropes. Elevator installation work was carried out using the fixed scaffolding method, in which the scaffolding materials assembled on the scaffolding boards and cross beams were dismantled and removed.

By the way, the fixed scaffolding described above is efficient when installing an elevator in a low-rise building because the assembly work is simple and the order of installation work can be easily changed, but it is not effective when installing an elevator in a high-rise building. In elevator installation work, scaffolding materials and scaffolding boards are installed along the entire length of the hoistway, which requires a great deal of labor and expense to assemble and dismantle, and the labor required to move workers up and down is also significant. There was a problem that it was extremely large and reduced the overall work efficiency, so for example, as disclosed in Japanese Patent Publication No. 16287-1987,
A hoisting machine for the permanent installation is installed in the machine room provided above the hoisting path, and the car frame for the main installation suspended by this hoisting machine is used as a work floor for the scaffolding for installation work, and the hoisting machine is installed. A moving scaffold construction method is used in which equipment is attached to the guide rail and the hoistway while the car frame is driven and raised along a guide rail that has been previously suspended from a machine room.

According to the conventional installation method described above, it has become possible to significantly improve the efficiency and safety of installation work.

[Problem that the invention attempts to solve]

However, the above-mentioned installation method can only be used when a machine room is installed above the hoistway.

By the way, elevators do not necessarily have a machine room installed on one side of the hoistway; for example,
In hydraulic elevators and drum-type elevators, which have recently been installed in many small houses as simple elevators, the machine room is installed below the hoistway, so the installation method described above cannot be used. ,
In order to install centering members, it is still necessary to assemble a cross-shaped scaffold in the hoistway, or to use the car frame for the main installation as a work floor, it is necessary to install a hydraulic elevator. Among these, indirect drive type elevators require the above-mentioned cross-shaped scaffolding to be assembled first in order to install the hydraulic jack, and also in the case of the above-mentioned drum-type elevators, it is necessary to lift and lower the car. In order to attach the hanging vehicle installed above the hoistway, it is necessary to assemble a cross-shaped scaffolding as in the case of the above-mentioned hydraulic elevator.
As described above, such elevators still require the installation of cross-shaped scaffolding in the hoistway, which poses the problem of not only poor work efficiency during installation work but also a lack of safety.

The present invention was developed in view of the actual situation in the installation work of elevators that do not have a machine room above the hoistway. The purpose of the present invention is to provide a scaffold for elevator installation work that can improve performance and work efficiency.

[Means for solving problems]

In order to achieve the above object, the present invention provides an elevator installation scaffold for use when performing installation work in an elevator hoistway, between the work floor, the landing floor, and the upper wall of the opening in the frame wall. A support member comprising a pair of columns fixed to the platform, and a guide means provided on the hall floor side of these columns to allow the working floor to be freely moved in and out of the elevator hoistway through the opening; The present invention is characterized by comprising a pair of suspension bodies that are connected to the work floor and can be suspended from the support member in a position where the work floor is in a horizontal state.

[Effect]

A pair of support members are fixed to a landing near an opening provided between a hoistway and a landing, a working floor is attached to a working floor guide device, and the working floor is placed at an appropriate position in the hoistway. Feed out until the end and fix it. and,
The pair of suspension bodies are adjusted and fixed so that the work floor is suspended in a horizontal state. Since the scaffolding for this elevator installation work is installed in this way, assembly and disassembly can be easily performed, and the work floor can be safely moved in and out of the hoistway during assembly and disassembly. It is easy to carry out, and the work floor can be firmly supported, making installation work in elevators where there is no machine room above the hoistway safe and easy.
Moreover, it can be carried out efficiently.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The figure is a perspective view seen from the hoistway side when assembling the scaffold for elevator installation work according to the present invention. Opening 5 provided in 1
15 is a support member supported by using the landing floor 3 and the upper wall 2, which is an upper extension thereof, as a fulcrum;
The support member 15 has a guide groove 1 at the lower end of the support column 13.
7 and a guide device 18 having a tightening bottle 16, the upper end is provided with a handle 7 for extending and contracting the screw shaft 6 having a guard washer 10, and connected by a turnbuckle 11 for adjusting the length. It has a structure in which a connecting ring 8 is provided at the upper end to attach a hanging body 19 having shackle 9a, 9b at both ends. It is a work floor fixed to 18, and there are connecting rings 1 at two places on the left and right of the tip for attaching the hanging support 19.
