Definitions

  • the present invention relates to a method for changing the conveying height of an elevator system in a building under construction, a method for operating an elevator system in a building under construction and a sliding formwork for constructing an elevator shaft.
  • Elevator systems are often required during the construction phase before the building is completed. Elevator systems are required z. B. during the construction period to enable the construction workers to reach as great heights as possible in the building by means of the elevator. Likewise, when the lower floors of a building are completed before the upper floors, the elevators must already be available to people who are already using the completed floors. When construction progresses, the elevators must be able to serve the floors as quickly as possible.
  • a known solution for this type of construction time use is the so-called jump lift, in which the lifting height of the elevator is gradually increased by one or more floors each time the construction work has reached a sufficient height relative to the previous jump.
  • the temporary machine room is moved up the aforementioned number of floors, and all the components that depend on the head, such as B. the suspension ropes for the car, the speed limiter ropes and other components that are in the shaft, electrical equipment in the shaft, shaft cables, compensation cables, etc. are extended to cover the height of the entire completed shaft.
  • the temporary machine room has been lifted using the building's construction crane, among other things.
  • the problem in this case is that the elevator installation depends on the use of the construction crane.
  • the construction crane can also be needed at another location on the construction site at the same time, in which case the hoist is not available for use in the desired time or for a sufficient period of time. In the same way, it can be difficult to get a way to keep the construction crane for temporary use.
  • the object of the present invention is therefore to provide a method in which the temporary machine room can be positioned closer to the current construction stage.
  • This object is achieved by a method for changing the conveying height of an elevator system of a building under construction, the elevator system comprising an elevator shaft with a first displaceable platform which limits the conveying height upwards.
  • the first displaceable platform in the elevator shaft is moved upwards, the first platform being supported on a sliding formwork when moving.
  • support is also understood to mean indirect support, in which further components are arranged between the sliding formwork and the first platform. It is relevant that the weight of the first movable platform is at least partially introduced into the building via the sliding formwork.
  • the first displaceable platform is designed in particular as a temporary machine room.
  • a temporary machine room includes in particular a drive machine for the Elevator system. In many cases, this is already the drive machine that is used for the later continuous operation of the elevator system after the building has been completed.
  • the first displaceable platform has a roof structure.
  • the roof structure serves to protect the area below the roof structure from falling parts.
  • the roof structure is integrated into the first displaceable platform in order to achieve a particularly space-saving design.
  • the roof structure can also be designed as a second displaceable platform which is arranged above the first displaceable platform in the elevator shaft. In such a case, first the second displaceable platform and then the first displaceable platform are successively displaced upwards, both platforms being supported on the sliding formwork during displacement.
  • the elevator car can also be used in this area to transport passengers and / or material immediately after the first relocatable platform 25 has been relocated.
  • the elevator system therefore only has to be taken out of operation for a short time during the relocation of the first relocatable platform 25.
  • the support of the temporary working platform on the sliding formwork has the advantage that no additional Auxiliary platform must be brought in to support the temporary working platform.
  • the construction of a scaffolding from which the assembly is carried out is also not necessary.
  • At least one lifting device (or another tool) that is supported on the sliding formwork is used in step S5 during assembly. This has the advantage that the weight forces of the hoist or, if necessary, other tools are also absorbed by the sliding formwork. This makes it easier to install the elevator components.
  • the invention also relates to a sliding formwork for the construction of an elevator shaft of a building under construction, comprising a first anchorage which is designed to absorb the load of a first displaceable platform during the displacement of the first displaceable platform.
  • the first anchorage accordingly forms a load pick-up point or load attachment point.
  • this embodiment has the advantage that the first displaceable platform can be arranged particularly close to the current construction status.
  • the first anchorage is arranged in the middle in particular in order to symmetrically introduce the load of the first displaceable platform into the sliding formwork.
  • the first displaceable platform is designed in particular as a temporary machine room.
  • a temporary machine room includes, in particular, a drive machine for the elevator installation. In many cases, this is already the drive machine that is used for the later continuous operation of the elevator system after the building has been completed.
  • the sliding formwork is developed in such a way that the first anchorage is designed as a horizontally lying bolt.
  • Such a bolt can be integrated particularly well into the structure of known sliding formwork and is suitable for absorbing and carrying the required loads.
  • the sliding formwork preferably comprises one or more second anchorages which are designed to support a hoist (or another tool) during the assembly of elevator components.
  • the one or more second anchorages accordingly form a load pick-up point or load attachment point. This has the advantage that the weight forces of the hoist or possibly other tools are also absorbed by the sliding formwork can be. This makes it easier to install the elevator components.
  • at least one of the one or more second anchorages is designed as a lifting eye.
  • the sliding formwork is designed to support a temporary working platform, with at least one of the one or more aforementioned second anchorages in particular being usable for the support.
  • the temporary working platform can also be carried by an additional auxiliary platform.
  • the sliding formwork in particular the underside of the sliding formwork, has a cover in order to prevent foreign bodies from falling into the area below the sliding formwork.
  • the cover can also be arranged on the top of the sliding formwork. Since various elevator components are installed between the sliding formwork and the first movable platform, this area must be protected from falling foreign objects. In principle, it would be possible to provide a further protective roof in the elevator shaft for this purpose. However, a further protective roof to secure lateral installation space will take up, so that the first displaceable platform could not be arranged so close to the sliding formwork.
  • the cover is also designed to be watertight in order to reduce the penetration of water (in particular rainwater) and preferably to prevent it completely.
  • the sliding formwork has a circumferential seal. The penetration of water into the elevator shaft must be prevented in order to ensure reliable, controlled operation of the elevator system.
  • FIG.1 shows a cross section of an elevator system 13 of a building under construction.
  • the elevator system 13 comprises an elevator shaft 15 which is erected together with the building.
  • a so-called sliding formwork 17 is used to construct the elevator shaft 15.
  • the use of sliding formwork for concreting building walls is well known and is only explained schematically here.
  • the shaft walls 19 have already been partially erected.
  • the top floor currently under construction is referred to as current construction stage 20.
  • the sliding formwork 17 is located above the shaft walls 19 that have already been erected.
  • the sliding formwork 17 is a mobile platform from which more and more liquid concrete is applied in order to further increase the height of the shaft walls 19.
  • the sliding formwork 17 itself is successively mixed with the applied liquid concrete.
  • the sliding formwork 17 is relocated with the aid of climbing poles 21 which extend in casing pipes 23. In this way, the sliding formwork 17 is supported on the lower sections of the shaft wall 19 that have already cured.
  • the sliding formwork 17 does not have to be supported by a separately erected scaffolding, but is supported on the shaft walls 19 erected with its help.
  • the sliding formwork 17 is dismantled.
  • the climbing poles 21 are then removed from the casing tubes 23 for reuse.
  • the casing pipes 23 themselves remain in the newly erected shaft wall 19.
  • a first displaceable platform 25 of the elevator system 13 is located in the elevator shaft 15.
  • the first displaceable platform 25 is designed as a temporary machine room 27.
  • the first displaceable platform 25 is a car 29 which is used to transport passengers and / or material.
  • the car 29 is coupled to a counterweight 33 via a support cable 31.
  • the support cable 31 is guided over a pulley 35 and a drive pulley 37.
  • the traction sheave 37 is coupled to a drive machine 39 of the elevator installation 13.
  • the car 29 is also connected to the counterweight 33 via a lower cable 41.
  • the lower rope 31 is guided over two pulleys 43 which are arranged in the shaft pit 45.
  • the car 29 is only used for transport up to a first delivery height, since the first displaceable platform 25 limits the delivery height upwards.
  • the elevator shaft 15 is simply completed only up to the first conveying height, so that the car 29 can only be used for transport up to the first conveying height.
  • the first displaceable platform 25 is moved upwards in the elevator shaft 15. It goes without saying that during this relocation of the first relocatable platform 25, the support cable 31 and the lower cable 41 must also be lengthened.
  • the speed limiter cable (not shown) must also be extended.
  • the sliding formwork 17 has a first anchorage 49 which is designed to take up the load of a first displaceable platform 25 during the displacement of the first displaceable platform 25.
  • the first displaceable platform 25 is designed as a temporary machine room 27.
  • the first anchorage 49 is therefore designed to take up the load of a temporary machine room 27 during the displacement of the temporary machine room 27.
  • the first anchorage is preferably arranged in the middle of the sliding formwork 17 in order to introduce the load symmetrically into the sliding formwork 17.
  • the first anchorage 49 is designed as a horizontally lying bolt 50.
  • the connection between the first relocatable platform 25 and the shaft walls 19 is released, so that the load of the first relocatable platform 25 is taken up by the sliding formwork 17 .
  • the load of the first displaceable platform 25 is absorbed by the shaft walls 19.
  • the shaft walls 19 have recesses 51 on which the first displaceable platform 25 is supported with the aid of extendable supports 53. To move the first displaceable platform 25, these supports 53 are retracted so that the load then passes over the cable 47 to the first anchorage 49 and thus to the sliding formwork 17.
  • a winch (not shown) is used for the relocation itself, with the aid of which the first relocatable platform 25 is pulled up by means of the rope 47 at the first anchorage 49.
  • the first displaceable platform 25 is then fastened again to the shaft walls 19. For example, this is done in turn by introducing the extendable supports 53 into correspondingly higher recesses 55 in the shaft walls 19.
  • the elevator car 29 can now be used for Transport of passengers and / or material up to a second, increased head can be used.
  • the first displaceable platform 25 has a roof structure 57.
  • the roof structure 57 serves to protect the area below the roof structure 57 from falling parts.
  • the roof structure 57 is integrated into the first displaceable platform 25 in order to achieve a particularly space-saving design.
  • the roof structure can also be designed as a second displaceable platform which is arranged above the first displaceable platform 25 in the elevator shaft 15. In such a case, first the second displaceable platform and then the first displaceable platform 25 are successively displaced upwards, both platforms being supported on the sliding formwork 17 during displacement.
  • the upper part of the elevator shaft 15 between the first movable platform 25 and the sliding formwork 17 can be upgraded for the operation of the elevator system 13 in this part.
  • a temporary working platform 59 is introduced into the elevator shaft 15 between the first displaceable platform 25 and the sliding formwork 17.
  • elevator components in particular guide rails
  • the elevator car 29 can also be used in this area to transport passengers and / or material immediately after the first relocatable platform 25 has been relocated.
  • the elevator installation 13 therefore only has to be taken out of operation for a short time while the first movable platform 25 is being moved.
  • the temporary working platform 59 is preferably also supported on the sliding formwork 17.
  • the sliding formwork has one or more second anchors 61, the second anchors 61 are designed in particular as load lugs.
  • the one or more second anchorages 61 are designed to support a hoist during the assembly of elevator components. For example, a winch can be attached to one of the second anchorages 61. This winch can then be used to lift guide rails into the desired position.
  • the underside of the sliding formwork 17 has a cover 63 in order to prevent foreign bodies from falling into the area below the sliding formwork 17.
  • the cover 63 is also designed to be waterproof in order to reduce the penetration of water (in particular rainwater) and preferably to prevent it completely.
  • the sliding formwork 17 has a circumferential seal 65. The circumferential seal 65 is arranged between the cover 63 and the shaft walls 19.
