Abstract

The invention relates to a method for constructing an elevator, comprising providing an elevator car; providing plurality of prefabricated hoistway modules to be piled on top of each other, each hoistway module bordering a hoistway space into which the whole elevator car or at least an upper or lower end thereof can be fitted to move; and piling said plurality of prefabricated modules on top of each other, such that the hoistway spaces of the prefabricated modules are vertically aligned forming a continuous vertically elongated hoistway where the elevator car can be fitted to move; and arranging the elevator car to be vertically movable in the hoistway. The invention also relates to an elevator obtained with the method.

First claim

The invention claimed is:

1. A method for constructing an elevator, comprising
providing an elevator car;
providing a plurality of prefabricated hoistway modules to be piled on top of each other, each separate prefabricated hoistway module of the plurality of prefabricated hoistway modules bordering a separate hoistway space into which an entire elevator car or at least an upper or lower end thereof can be fitted to move, such that the plurality of prefabricated hoistway modules border separate, respective hoistway spaces into which the entire elevator car or at least the upper or lower end thereof can be fitted to move;
piling the plurality of prefabricated hoistway modules on top of each other to form a piled plurality of prefabricated hoistway modules, such that the separate, respective hoistway spaces of the plurality of prefabricated hoistway modules are vertically aligned with each other to form a continuous vertically elongated hoistway where the elevator car can be fitted to move; and
arranging the elevator car to be vertically movable in the hoistway space,
wherein the plurality of prefabricated hoistway modules includes a prefabricated top module, the prefabricated top module being an uppermost prefabricated hoistway module in the piled plurality of prefabricated hoistway modules, and
wherein the prefabricated top module includes
a machinery configured to drive a hoisting roping, and
one or more car guide rail sections,

wherein the machinery configured to drive the hoisting roping is mounted on a single car guide rail section of the one or more car guide rail sections of the prefabricated top module, such that the single car guide rail section is configured to carry both a complete weight of the machinery and a load exerted by the hoisting roping passing around a drive wheel of the machinery,
wherein the single car guide rail section and a separate car guide rail section of the one or more car guide rail sections are fixed to different horizontal beams such that the single car guide rail section and the separate car guide rail section are fixed to the horizontal beams configured to be on opposite sides of the elevator car in the hoistway space.

2. The method according to claim 1 , wherein
each separate prefabricated hoistway module of the plurality of prefabricated hoistway modules comprises a separate tubular frame around the separate hoistway space of the separate prefabricated hoistway module, such that the plurality of prefabricated hoistway modules include separate, respective tubular frames, and
the separate tubular frame forms a bearing structure of the separate prefabricated hoistway module.

3. The method according to claim 2 , wherein
each given tubular frame of each given prefabricated hoistway module underlying the prefabricated top module in the piled plurality of prefabricated hoistway modules carries a weight of an overlying tubular frame of all prefabricated hoistway modules overlying the given prefabricated hoistway module in the piled plurality of prefabricated hoistway modules.

4. The method according to claim 2 , wherein
each separate prefabricated hoistway module of the plurality of prefabricated hoistway modules comprises one or more car guide rail sections, such that the plurality of prefabricated hoistway modules include separate, respective car guide rail sections, and
the one or more car guide rail sections are each fixed on the separate tubular frame with at least one fixing bracket.

5. The method according to claim 4 , wherein the piling the plurality of prefabricated hoistway modules on top of each other to form the piled plurality of prefabricated hoistway modules causes the separate, respective car guide rail sections of the plurality of prefabricated hoistway modules to become vertically aligned with each other to form one or more continuous vertical guide rail lines configured to guide the elevator car.

6. The method according to claim 2 , further comprising:
providing a counterweight,
wherein each separate prefabricated hoistway module of the plurality of prefabricated hoistway modules includes one or more counterweight guide rail sections, such that the plurality of prefabricated hoistway modules include separate, respective counterweight guide rail sections, and
wherein the one or more counterweight guide rail sections of the separate prefabricated hoistway module are fixed on the separate tubular frame of the separate prefabricated hoistway module with at least one fixing bracket.

7. The method according to claim 6 , wherein the piling the plurality of prefabricated hoistway modules on top of each other to form the piled plurality of prefabricated hoistway modules causes the separate, respective counterweight guide rail sections of the plurality of prefabricated hoistway modules to become vertically aligned with each other to form one or more continuous vertical guide rail lines configured to guide the counterweight.

8. The method according to claim 2 , wherein each separate tubular frame of the separate, respective tubular frames is a beam frame.

9. The method according to claim 8 , wherein the beam frame comprises the horizontal beams, vertical beams and diagonal beams rigidly connected together.

10. The method according to claim 9 , wherein
each separate prefabricated hoistway module of the plurality of prefabricated hoistway modules comprises one or more car guide rail sections, and each of the one or more car guide rail sections is fixed with at least one fixing bracket on at least one of the horizontal beams of the beam frame of the separate prefabricated hoistway module; and/or
each separate prefabricated hoistway module of the plurality of prefabricated hoistway modules comprises one or more counterweight guide rail sections, and each of the one or more counterweight guide rail sections is fixed with at least one fixing bracket on at least one of the horizontal beams of the beam frame of the separate prefabricated hoistway module.

11. The method according to claim 2 , wherein the separate tubular frame of the separate prefabricated hoistway module is a concrete frame comprising concrete or reinforced concrete, the concrete or reinforced concrete forming more than 50% of a weight of the concrete frame.

12. The method according to claim 11 , wherein the concrete frame comprises four vertical concrete walls rigidly connected together and bordering the separate hoistway space bordered by the separate prefabricated hoistway module.

13. The method according to claim 11 , wherein the concrete frame comprises a horizontal beam embedded in concrete of the concrete frame.

14. The method according to claim 1 , wherein the arranging includes arranging the elevator car to be vertically movable in the continuous vertically elongated hoistway along one or more car guide rail lines configured to guide the elevator car.

15. The method according to claim 1 , wherein the plurality of prefabricated hoistway modules comprise one or more of
a prefabricated pit module, or
one or more prefabricated intermediate modules into and through which an entire elevator car can be fitted to move.

16. The method according to claim 1 , wherein the prefabricated top module comprises
a plurality of car guide rail sections including the single car guide rail section and the separate car guide rail section,
a first rope fixing bracket configured to be fixed to a first end of the hoisting roping and further fixed to the separate car guide rail section such that the separate car guide rail section is configured to vertically carry a load exerted by the hoistin
