Abstract

A method for constructing an elevator into a destination location from a plurality of prefabricated elevator modules includes fabricating a plurality of elevator modules, in particular at a location apart from said destination location. The fabricating includes providing one or more module frames having a longitudinal axis; positioning one or more of the module frames in horizontally oriented position, wherein in the horizontally oriented position the longitudinal axis is horizontal; and while the one or more module frames are in the horizontal position, performing installation work on said one or more module frames. The method includes arranging the modules into the destination location on top of each other such that said modules are in a vertically oriented position.

First claim

The invention claimed is:

1 . A method for constructing an elevator into a destination location from a plurality of prefabricated elevator modules, the method comprising:
fabricating the plurality of prefabricated elevator modules, said fabricating comprising the steps of:
providing one or more module frames having a longitudinal axis;
positioning one or more of the module frames in a horizontally oriented position, wherein in said horizontally oriented position the longitudinal axis is horizontal; and
while the one or more module frames are in the horizontal position, performing installation work on said one or more module frames;
transporting the elevator modules to a proximity of the destination location; and arranging the elevator modules into the destination location on top of each other such that said elevator modules are in a vertically oriented position, wherein in said vertically oriented position the longitudinal axes of the module frames of the elevator modules are vertical, wherein the installation work comprises adjusting positions of corner beams of a module frame relative to each other and/or relative to corner beams of another module frame connected to the module frame in question, and wherein said adjusting positions of corner beams is performed such that cross dimensions of corner beams of a module frame are changed.

2 . The method according to claim 1 , wherein in said positioning, two of the module frames are positioned in the horizontally oriented position, and the fabricating comprises thereafter connecting to each other said two module frames end to end while they are in the horizontal position, and thereafter installation work is performed on one or both of said two module frames while they are in the horizontal position and connected.

3 . The method according to claim 2 , wherein the installation work on one or both of said two module frames while they are in the horizontal position and connected comprises fixing on at least one of the module frames elevator parts such that they are aligned with corresponding elevator parts fixed to another module frame connected to the module frame in question.

4 . The method according to claim 3 , wherein said elevator parts include one or more of: guide rail brackets for guide rails; car guide rails; counterweight guide rails; and landing door structures.

5 . The method according to claim 3 , wherein said fixing is performed by aid of a laser device emitting a laser ray.

6 . The method according to claim 2 , wherein connecting of two module frames to each other end to end is performed by aid of shape-locking connectors, the shape-locking connectors being at ends of the two module frames to be connected.

7 . The method according to claim 1 , wherein each said module frame is a beam frame, each said module frame comprising four corner beams.

8 . The method according to claim 7 , wherein each said module frame comprises cross beams connecting the corner beams to each other.

9 . The method according to claim 1 , wherein each said module frame comprises cross beams connecting the corner beams to each other.

10 . The method according to claim 1 , wherein the arranging comprises connecting successive modules to each other, comprising reconnecting to each other two module frames of said one or more module frames end to end while they are in the vertical position, which two module frames were earlier connected during fabricating of the plurality of elevator modules.

11 . The method according to claim 1 , wherein said module frames comprise a pit module frame, at least one intermediate module frame and a top module frame, and said elevator modules comprise a pit module comprising a pit module frame, at least one intermediate module comprising an intermediate module frame and a top module comprising a top module frame, and in said arranging the elevator modules are arranged into the destination location on top of each other such the at least one intermediate module is/are on top of the pit module and the top module is on top of the at least one intermediate module.

12 . The method according to claim 1 , wherein said adjusting positions of corner beams comprises adjusting position of one or more corner beams such that they become parallel or within a tolerance away from parallel.

13 . The method according to claim 1 , wherein said adjusting positions of corner beams is performed by aid of a laser device emitting a laser ray.

14 . The method according to claim 1 , wherein the installation work comprises fixing on a module frame while the module frame is in the horizontal position one or more of:
a hoisting machine unit comprising at least a hoisting machine and a car guide rail section, the hoisting machine comprising a drive sheave for engaging hoisting ropes and an electric motor for driving the drive sheave; and/or rope end fixing brackets.

15 . The method according to claim 1 , wherein the fabricating comprises assembling on a module frame, while the module frame is in the vertical position, an elevator car, such that the elevator car is mounted on guide rails fixed to the module frame.

16 . The method according to claim 1 , wherein the method comprises after said arranging, roping the elevator.

17 . A method for constructing an elevator into a destination location from a plurality of prefabricated elevator modules, the method comprising:
fabricating the plurality of prefabricated elevator modules, said fabricating comprising the steps of:
providing one or more module frames having a longitudinal axis;
positioning one or more of the module frames in a horizontally oriented position, wherein in said horizontally oriented position the longitudinal axis is horizontal; and
while the one or more module frames are in the horizontal position, performing installation work on said one or more module frames;
transporting the elevator modules to a proximity of the destination location; and
arranging the elevator modules into the destination location on top of each other such that said elevator modules are in a vertically oriented position, wherein in said vertically oriented position the longitudinal axes of the module frames of the elevator modules are vertical,
wherein in said positioning, two of the module frames are positioned in the horizontally oriented position, and the fabricating comprises thereafter connecting to each other said two module frames end to end while they are in the horizontal position, and thereafter installation work is performed on one or both of said two module frames while they are in the horizontal position and connected, and
wherein the installation work performed on one or both of said two module frames while they are in the horizontal position and connected comprises making aligned markings on the module frames to plurality of positions for indicating intended locations of parts to be fixed on the module frames.

18 . A method for constructing an elevator into a destination location from a plurality of prefabricated elevator modules, the method comprising:
fabricating the plurality of prefabricated elevator modules, said fabricating comprising the steps of:
providing one or more module frames having a longitudinal axis;
positioning one or more of the module frames in a horizontally oriented position, wherein in said horizontally oriented position the longitudinal axis is horizontal; and
while the one or more module frames are in the horizontal position, performing installation work on said one or more module frames;
transporting
