Abstract

Method and arrangement in the manufacture of an elevator, which includes during construction time an elevator hoistway, an elevator car, hoisting roping, a supporting structure including a plurality of support elements movable between a position extended from the supporting structure towards the side and a position retracted towards the supporting structure, and a platform. A plurality of lifts are performed, in each of which lifts the supporting structure is lifted higher up in the elevator hoistway, while the support elements are in the retracted position, after which the support elements are displaced into the extended position and the supporting structure is lowered to rest on top of the structures of the building supported by the support elements in the extended position for the vertical support of the supporting structure in the elevator hoistway, and between lifts the elevator car is used for transporting passengers and/or freight between floors.

First claim

The invention claimed is:

1. A method in the manufacture of an elevator, which elevator comprises, during a construction-time,
an elevator hoistway,
an elevator car,
hoisting roping for supporting and moving the elevator car during use of the elevator car,
a supporting structure movable in a vertical direction for supporting the elevator car below it in the elevator hoistway, which supporting structure comprises:
a plurality of support elements movable between a position extended, from the supporting structure towards a side of the elevator hoistway, and a position retracted, towards the supporting structure, and
a platform, which supports a rope pulley, supported by which the hoisting roping is arranged to hang,

in which method plurality of lifts are performed, in each of which lifts the supporting structure is lifted higher up in the elevator hoistway, while the plurality of support elements is in the retracted position, after which the plurality of support elements is displaced into the extended position and the supporting structure is lowered to rest on top of the structures of the building, whereby the supporting structure is supported by the plurality of support elements in the extended position for a vertical support of the supporting structure in the elevator hoistway, in which method, between lifts, the elevator car is used for transporting passengers and/or freight between floors, wherein the plurality of support elements is above the rope pulley and hoisting roping.

2. The method according to claim 1 , wherein the elevator hoistway comprises on one of its sides a plurality of openings leading onto floor landings, and the supporting structure comprises an apron that extends downwards, or that can be displaced to extend downwards, from an edge of the platform on a side of the platform opposite the openings and leading to one of the floor landings for covering a gap between the edge of the platform and a sill of said one of the floor landings.

3. The method according to claim 2 , wherein in the method a lift is performed, after which the supporting structure is supported in the elevator hoistway such that its platform is at a point of an opening of another floor landing above said one of the floor landings, the apron essentially covers, or is arranged to essentially cover, a gap between an edge of the platform and a sill of said another floor landing.

4. The method according to claim 2 , wherein the supporting structure comprises a second platform above the platform, and that in the method a lift is performed, after which the supporting structure is supported in the elevator hoistway such that the second platform is essentially at a height of another floor landing.

5. The method according to claim 1 , wherein the supporting structure comprises a second platform above said platform, and that in the method a lift is performed, after which the supporting structure is supported in the elevator hoistway such that the second platform is essentially at a height of a floor landing.

6. The method according to claim 1 , wherein the platform is climbed up to from a floor landing along steps and/or the platform is climbed down to the floor landing along steps.

7. The method according to claim 1 , wherein in the method a lift is performed, after which the supporting structure is supported in the elevator hoistway such that the plurality of support elements is essentially at a height of a floor landing.

8. The method according to claim 1 , wherein in the method a lift is performed, after which the supporting structure is supported in the elevator hoistway such that the plurality of support elements of said supporting structure rest on a top surface of an edge of a floor landing and on a top surface of a supporting structure on a side of the elevator hoistway opposite the floor landing.

9. The method according to claim 1 , wherein the rope pulley is a traction sheave of a hoisting machine.

10. The method according to claim 1 , wherein the supporting structure comprises a second platform above the rope pulley, in connection with which second platform the support elements are provided.

11. The method according to claim 1 , wherein the platform and/or the second platform comprises a flat standing surface.

12. The method according to claim 1 , wherein the plurality of support elements can be telescopically displaced relative to a frame part of the supporting structure between a retracted and an extended position.

13. The method according to claim 1 , wherein the plurality of support elements can be displaced in a horizontal direction, with a linear movement, between a retracted and an extended position.

14. The method according to claim 1 , wherein the plurality of support elements comprises support elements that can be displaced in opposite lateral directions into an extended position.

15. The method according to claim 1 , wherein the plurality of support elements are supported on a frame part of the supporting structure, said frame part being above the rope pulley, which frame part is a beam structure, which at least partly forms the second platform.

16. The method according to claim 1 , wherein the arrangement comprises steps for ascending/decending from/to a floor landing to/from the platform descending.

17. The method according to claim 1 , wherein the supporting structure is supported in the elevator hoistway such that its platform is at a point of the opening of a floor landing essentially above the floor landing, and in that the arrangement comprises an apron, which covers, or can be arranged to at least essentially cover, a gap between an edge of the platform and a sill of the floor landing.

18. An elevator arrangement during construction of the elevator, which elevator arrangement comprises:
an elevator hoistway,
an elevator car,
hoisting roping for supporting and moving the elevator car during use of the elevator car,
a supporting structure movable in a vertical direction for supporting the elevator car below it in the elevator hoistway via hoisting roping, which supporting structure comprises:
a plurality of support elements movably supported on the supporting structure and movable between a position extended, from the supporting structure towards a side of the elevator hoistway, and a position retracted, towards the supporting structure, supported by which plurality of support elements in the extended position the supporting structure can be lowered to rest on top of structures of a building for a vertical support of the supporting structure in the elevator hoistway, and when in the retracted position of which plurality of support elements the supporting structure can be displaced in the vertical direction in the elevator hoistway without being obstructed by the plurality of support elements; and
a platform, which supports a rope pulley, supported by which the hoisting roping is arranged to hang,
wherein the plurality of support elements is above the rope pulley and the hoisting roping.

19. The arrangement according to claim 18 , wherein the elevator hoistway comprises on one of its sides a plurality of openings leading onto floor landings, and the supporting structure comprises an apron that extends downwards, or that can be displaced to extend downwards, from an edge of the platform on a side of platform opposite the plurality of openings and leading to one of the floor landings for covering a gap between the edge of the platform and a sill of said one of the floor landings.
