Abstract

A method and elevator arrangement wherein a roof structure is lifted higher in a hoistway so as to make more room below the roof structure, the roof structure being a movable roof structure, and in that the movable roof structure is lifted in the hoistway taking support for the lift from a second movable support structure mounted in the hoistway above the roof structure.

First claim

The invention claimed is:

1. A method of constructing an arrangement to install an elevator, the arrangement including at least one elevator unit including an elevator car, a first movable support structure and a second movable support structure arranged in a hoistway with a third movable support structure therebetween, such that the first movable support structure is configured to support the at least one elevator unit, the third movable support structure is configured to support the first movable support structure, and the second movable support structure is configured to support a movable roof structure arranged above the third movable support structure in the hoistway, the third movable support structure having a separation deck thereon to catch objects that fall from a movable working platform above the separation deck, the separation deck having an impact absorbing sandwich structure to dissipate a kinetic energy of the objects that fall from the movable working platform, the method comprising:
disabling the elevator car from moving in the hoistway;
first lifting the first movable support structure towards the movable roof structure in the hoistway while supporting a weight thereof by the third movable support structure;
enabling the elevator car to transport the objects after the first lifting; and
second lifting, via a lifting arrangement while the elevator car is enabled, the movable roof structure higher in the hoistway when the first movable support structure approaches the movable roof structure a distance less than a first distance, wherein said second lifting increases the first distance.

2. The method according to claim 1 , further comprising:
third lifting, via a second rope, at least part of the lifting arrangement to a level of a mounting position after the second lifting is performed.

3. The method according to claim 2 , wherein the third lifting includes at least one of lifting a first rope attached to the second movable support structure and the second movable support structure to the level of the mounting position.

4. The method according to claim 2 , wherein the third lifting includes,
dropping the second rope vertically in the hoistway,
connecting the second rope to the part of the lifting arrangement, and
lifting the part by pulling the second rope.

5. The method according to claim 2 , wherein as the second lifting moves the movable roof structure higher in the hoistway, the movable roof structure approaches the second movable support structure, and the method further comprising:
fourth lifting the second movable support structure higher in the hoistway such that the fourth lifting increases a second distance between the second movable support structure and the movable roof structure.

6. The method according to claim 1 , wherein the impact absorbing sandwich structure includes a first skin, a second skin, and one or more core elements between the first skin and the second skin.

7. The method according to claim 6 , wherein the one or more core elements comprise:
a fiber board, a steel plate, and a corrugated sheet, the corrugated sheet being vertically superimposed between the steel plate and the second skin.

8. The method according to claim 1 , wherein the lifting arrangement includes the second movable support structure arranged in a mounting position above the movable roof structure, a first rope and a lifting device.

9. The method according to claim 1 , wherein the third movable support structure is lifted higher in the hoistway using the support of the movable roof structure, before the first lifting is performed.

10. The method according to claim 1 , wherein the movable working platform is below the movable roof structure, the movable working platform configured to provide support to a user while the user is installing elevator structures.

11. The method according to claim 1 , wherein after the second lifting, part of the lifting arrangement is lowered below a water-proof roof part of the movable roof structure.

12. The method according to claim 1 , wherein the second lifting includes lifting the movable roof structure with the lifting arrangement in the hoistway, the lifting arrangement including a lifting device within the movable roof structure.

13. The method according to claim 1 , wherein the movable roof structure comprises:
a protection deck with an impact absorbing sandwich structure.

14. An elevator installation arrangement, comprising:
a hoistway;
at least one elevator unit including an elevator car movable in the hoistway;
a movable roof structure configured to protect the hoistway;
a plurality of movable support structures including a first movable support structure and a second movable support structure arranged in the hoistway with a third movable support structure therebetween, such that the first movable support structure is configured to support the at least one elevator unit, the third movable support structure being configured to support the first movable support structure, and the second movable support structure being configured to support the movable roof structure arranged above the third movable support structure in the hoistway;
a lifting arrangement configured to lift the movable roof structure higher in the hoistway to increase a first distance between the first movable support structure and the movable roof structure while the elevator car is enabled, the lifting arrangement including the second movable support structure arranged above the movable roof structure, the second movable support structure configured to support the movable roof structure while lifting the movable roof structure;
a movable working platform below the movable roof structure; and
a separation deck on the third movable support structure below the movable working platform to catch objects that fall from the movable working platform, the separation deck having an impact absorbing sandwich structure to dissipate a kinetic energy of the objects that fall from the movable working platform.

15. The elevator installation arrangement according to claim 14 , wherein the movable roof structure comprises:
a platform configured to support a user thereon; and
a water-proof roof part above the platform.

16. The elevator installation arrangement according to claim 15 , wherein the movable roof structure further comprises:
a protection deck with an impact absorbing sandwich structure above the platform.

17. The elevator installation arrangement according to claim 14 , wherein the impact absorbing sandwich structure comprises:
a first skin, a second skin, and one or more core elements between the first skin and the second skin.

18. The elevator installation arrangement according to claim 17 , wherein the one or more core elements comprise:
a fiber board, a steel plate, and a corrugated sheet, the corrugated sheet being vertically superimposed between the steel plate and the second skin.

19. The elevator installation arrangement according to claim 14 , wherein the movable roof structure includes a protection deck with an impact absorbing sandwich structure.

20. The elevator installation arrangement according to claim 14 , wherein the movable roof structure includes a water-proof membrane configured to water-proof the movable roof structure.

21. The elevator installation arrangement according to claim 14 , wherein the second movable support structure is portable or consists of detachably connected portable parts.

22. The elevator installa
