Abstract

A method and construction site device for vertical transportation during a building construction phase include a climbing formwork platform arranged in a currently uppermost region of the building for concreting at least part of the building core, an elevator car intermittently adjusted to a current building height in a first elevator shaft by hoisting a mechanical platform to a higher level and fixing it there, a construction elevator temporarily installed in a second elevator shaft and attached to the climbing formwork platform with a construction elevator car vertically movable in a construction elevator frame, and wherein people and/or material are transported to a floor associated with an access opening of the construction elevator by the elevator system and then are transported from this floor to a floor situated in the currently uppermost region of the building or to the climbing formwork platform by the construction elevator.

First claim

The invention claimed is:

1. A method for vertical transportation of people and/or material in a building during a construction phase of the building, the method comprising the steps of:
arranging a climbing formwork device in a currently uppermost region of the building to concrete at least part of a building core of the building, the climbing formwork device including a climbing formwork platform and being adapted to be hoisted in steps;
installing an elevator system in a first elevator shaft of the building, the elevator system adapted to adjust to an increasing building height and having an elevator car, wherein a conveying height of the elevator system is intermittently adjusted to a current building height by hoisting a mechanical platform including an elevator drive machine to a higher level and fixing the mechanical platform in the first elevator shaft, and wherein at least two currently uppermost floors of the building cannot be reached by the elevator car after the conveying height is adjusted;
installing a construction elevator temporarily in a second elevator shaft in the currently uppermost region of the building and attaching the construction elevator to the climbing formwork platform, wherein the construction elevator includes a construction elevator frame, a construction elevator car vertically movable in the construction elevator frame, and at least two access openings arranged in the construction elevator frame and corresponding to adjacent shaft door clearances in a shaft wall of the second elevator shaft;
transporting people and/or material by the elevator system to a first floor in the building associated with one of the at least two access openings; and
transporting the people and/or material from the first floor to a higher second floor in the currently uppermost region of the building or to the climbing formwork platform using the construction elevator.

2. The method according to claim 1 including hoisting the climbing formwork platform in steps each corresponding to a whole floor height.

3. The method according to claim 1 including using the elevator system during the construction phase of the building to transport people and/or material in a region of already inhabited or commercially used floors of the building, and after completion of the building leaving the elevator system permanently installed for use as a building elevator system.

4. The method according to claim 1 wherein a part of the construction elevator lying below the climbing formwork platform is high enough that a floor of the building currently adjacent to a lowermost one of the at least two access openings can be reached by the elevator car of the elevator system when the mechanical platform is temporarily positioned at a predetermined maximum vertical distance from the climbing formwork platform.

5. The method according to claim 1 wherein the construction elevator car has a conveying height that is in a range of four times to ten times an average floor height of the building.

6. The method according to claim 1 including steps of delivering the construction elevator to a construction site of the building as a unit preassembled in a manufacturing plant, lowering the unit into the second elevator shaft using a hoisting device, and attaching the unit to the climbing formwork platform of the climbing formwork device.

7. The method according to claim 1 wherein further access openings with assigned shaft doors are arranged on the construction elevator frame between a lowest one of the at least two access openings and an uppermost one of the at least two access openings.

8. The method according to claim 1 wherein the construction elevator is attached to the climbing formwork platform of the climbing formwork device such that an uppermost region of the construction elevator frame with an uppermost access opening and a top shaft door protrude upwards beyond the climbing formwork platform.

9. The method according to claim 1 wherein the construction elevator is attached to the climbing formwork platform of the climbing formwork device such that an entirety of construction elevator frame lies below the climbing formwork platform.

10. The method according to claim 1 wherein the construction elevator frame of the construction elevator extends at least over an entire conveying height of the construction elevator car, the construction elevator car is equipped with a first car door, a drive device for raising and lowering the construction elevator car is installed at the construction elevator frame, and the at least two access openings in a locking position of the climbing formwork device correspond to the shaft door clearances in the shaft wall of the second elevator shaft, wherein shaft doors that work together with the first car door of the construction elevator car are attached to the construction elevator frame to close off the shaft door clearances.

11. The method according to claim 10 wherein the at least two access openings and the shaft doors are arranged on the construction elevator frame such that levels of door sills of the shaft doors arranged below the climbing formwork platform match with levels of floors already constructed in the building when the climbing formwork device is in one of a plurality of predetermined locking positions, wherein at each of the locking positions another wall section of the building core is concreted with a wall section height corresponding to a floor height for the building.

12. The method according to claim 10 wherein at least one of the at least two access openings and an associated one of the shaft door are arranged on the construction elevator frame such a vertical position of the at least one access opening and the associated shaft door to be adjusted to different floor heights or to different distances between floor levels of the building.

13. The method according to claim 10 wherein the construction elevator is arranged in the second elevator shaft such that a first side of the construction elevator having the first car door and the shaft doors that work together with the first cabin door lie parallel to and adjacent to a first shaft wall of the second elevator shaft containing the shaft door clearances, wherein a second side of the construction elevator and a second shaft wall of the second elevator shaft parallel to the second side are spaced apart by at least 0.5 meters, wherein a second car door parallel to the second side of the construction elevator is attached to the construction elevator car and at least one access opening corresponding with the second car door and having an associated shaft door is attached to the construction elevator frame, and wherein, at a level of a door sill of the at least one shaft door corresponding to the second car door, in a space available between the second side of the construction elevator and the second shaft wall of the second elevator shaft parallel thereto, a walkable, horizontal platform is attached to the construction elevator frame, via which platform access to an interior of the second elevator shaft is possible from the construction elevator.

14. The method according to claim 10 wherein information about a current vertical position of the construction elevator is transmitted to a controller of the elevator system, and the controller evaluates the position information to determine a transfer floor to which both the elevator car and the construction elevator car can move as a transfer stop for moving the people and/or material between the elevator system and the construction elevator.

15. A construction site device adapted to perform the steps of the m
