Definitions

  • the present invention relates to a method for retrofitting a building with an elevator system with a prefabricated shaft, as well as a set of components for carrying out the method.
  • the prefabricated shaft extends over at least two floors and includes a self-supporting sheet metal box which is intended to accommodate a car of the elevator system together with its guides and drive devices, which may also contain a counterweight.
  • the at least one steel plate, which forms the self-supporting sheet metal box runs in a straight line in a longitudinal direction of the shaft, which corresponds to the direction of movement of the cabin, while it is profiled in a cross-sectional plane that is orthogonal to the longitudinal direction of the shaft.
  • Such a prefabricated shaft is from the EP 3 315 448 A2 known.
  • elevator shafts consist of a concrete or steel structure that is erected on site at the construction site. After the elevator shaft has been constructed, the actual elevator system is generally assembled on site by installing a cabin, its suspension and drive as well as all the components necessary for operation. This results in a total construction time of several weeks. This is particularly disadvantageous if the elevator system is used to retrofit an already existing and used building; Because access to the building is difficult during the construction phase.
  • the already mentioned EP 3 315 448 A2 proposed to make the sheet metal box with which the shaft is made from at least one steel plate which runs straight in the longitudinal direction of the shaft while being profiled in the cross-sectional plane;
  • the at least one steel plate is formed in one piece in the longitudinal direction over the entire extent of the shaft.
  • This self-supporting and stable design of the sheet metal box makes it possible, on the one hand, to transport the prefabricated shaft from the factory to the construction site using a truck;
  • the elevator system made with the self-supporting sheet metal box can be placed on an existing building due to its inherent stability without being supported on the building, so that the statics of the building remain unaffected and any recalculation of the same is unnecessary.
  • Elevator systems for attachment to a building or for retrofitting a building are usually used in older buildings where barrier-free access has not yet been taken into account.
  • residential buildings with a plurality of residential units that are spread over several floors but also administrative buildings and commercial buildings often have a plurality of floors, which are in particular divided into several residential units or other self-contained units have appropriate floor doors.
  • These floor doors are usually accessed via a shared staircase.
  • a common design of such multi-story houses integrates the stairwell at the front of the building, with an entrance door at ground level and a two-flight staircase that provides access to all floor doors via main landings on each floor and intermediate landings. In this design, these are located on the main platforms.
  • An elevator system is also known, which can be installed at a suitable external position of an existing building.
  • a corresponding building is to be modernized to be largely barrier-free by retrofitting an elevator system
  • a prefabricated elevator system or a prefabricated shaft has not yet been the method of choice to use the type mentioned at the beginning. Instead, it is necessary to gut the stairwell and completely rebuild it with an elevator system. Since access to the floor doors is generally not possible during the corresponding construction period, retrofitting a corresponding building with an elevator system is usually not done, at least from the point of view of maximum accessibility.
  • the present invention is therefore based on the object of proposing a method for retrofitting a building with an elevator system and a set of components for carrying out this method, with which a building with a plurality of floors and a staircase that adjoins a front of the building and per floor has a main platform and an intermediate platform for a two-flight staircase, can be retrofitted with an elevator system, at least largely barrier-free.
  • the prefabricated shaft for an elevator system used according to the invention for attachment to a building from the outside makes it possible to retrofit a building with an elevator system in a largely barrier-free manner even if the building is accessible via a stairwell with intermediate landings.
  • the shaft extends over at least two floors and includes a self-supporting sheet metal box made of at least one steel plate, which is intended to accommodate a car of the elevator system together with its guides and drive devices, i.e. possibly also a counterweight.
  • the at least one steel plate runs in a straight line in a longitudinal direction of the shaft, which corresponds to the direction of movement of the cabin, while it is profiled in a cross-sectional plane that is orthogonal to the longitudinal direction of the shaft is.
  • the at least one steel plate extends in one piece in the longitudinal direction of the shaft over the entire extent thereof, while two or more steel plates are placed together in the circumferential direction, as is known per se.
  • the sheet metal box of the shaft has a cross section that goes beyond the pure enclosure of the cabin and the other components:
  • the sheet metal box is profiled in such a way that a cross-sectional area is created in the cross-sectional plane within the sheet metal box, which is essentially that of the cabin and its guides as well as drive devices required area, as well as the area of an elevator platform to bridge a distance between the cabin and the building.
  • the prefabricated shaft is preferably made with an elevator platform per floor.
  • Such a prefabricated shaft, placed in front of the front of the building, can cover the entire width of the stairwell, so that when the building is retrofitted with the elevator system, it can be opened completely to the front of the building. Since there is space within the prefabricated shaft for an elevator platform that a person steps onto after leaving the cabin, the cabin can be arranged at a certain distance, namely the width of the elevator platform, in front of the front of the building, which increases the freedom of design inside the stairwell advantageously enlarged.
  • the traffic area in front of the elevator system in the stairwell is expanded to the same level;
  • the requirements for complete accessibility which, in addition to level access, also require maneuvering areas of typically 1.5 m x 1.5 m in front of an elevator door, can be easily met.
  • the metal box is provided with light openings in a wall adjacent to the elevator platforms. To increase the level of prefabrication, these light openings can already be equipped with windows when the prefabricated shaft is transported to the construction site.
  • the prefabricated shaft is provided with elevator platforms, these preferably have anchoring devices for anchoring to elements of the stairwell, these anchoring devices preferably producing a floating anchor between the elevator platform and a further platform or web inside the stairwell.
  • the sheet metal box of the prefabricated shaft is preferably essentially open on the side that faces the front of the building when assembled. In this way, the sheet metal box increases the enclosed space of the stairwell, and in particular the elevator platforms become part of the stairwell. In the area where the cabin is located moved within the metal box, this building side of the shaft can be provided with cross struts and panels so that only one passage opening remains free for getting in and out of the cabin.
  • the sheet metal box of the prefabricated shaft preferably has a passage opening on a side that is not the side of the building, which is in a position in which the elevator platform for the ground floor of the building is located after the elevator system has been attached to a building.
  • This passage opening thus forms the front door, which can be accessed via an external staircase, through which you can get into the building or the stairwell bypassing the elevator system.
  • it offers advantages if there is another passage opening at ground level on a side of the metal box that is not the building side of the shaft and through which the cabin inside the shaft is accessible from the outside at ground level. This ensures barrier-free access to the elevator system, even if the prefabricated shaft according to the invention is used to retrofit a building whose ground floor is half a floor above ground level.
  • the sheet metal box of the prefabricated shaft preferably has a base surface which is provided with fastening elements for attaching the shaft to a foundation, the fastening elements advantageously having adjusting devices in order to be able to align the shaft vertically on the foundation.
  • the prefabricated shaft For buildings whose entrance and stairwell are located on the front, the prefabricated shaft must be installed on this front.
  • the supply lines for fresh water, wastewater, electricity and information technology usually run there at a depth of typically 1.20 m below ground level.
  • a conventional prefabricated shaft is provided with an underpass below the lowest station of the cabin, in particular to provide sufficient movement path for a counterweight of the cabin. Since the lowest station approached by the cabin is for If there is to be a high degree of accessibility at ground level, the foundation of the elevator system needs to be excavated to a corresponding depth in order to create space for this underpass. To do this, however, the supply lines would have to be laid, which would involve a lot of effort and a period during which the building would not be usable.
  • the sheet metal box has a shortened underside and is extended upwards in accordance with this shortening. This makes it possible to build the foundation for the elevator system at a depth that is still above the supply line. This depth is typically between 0.8 m and 1.0 m.
  • the elevator system used according to the invention for attachment to a building from the outside comprises a prefabricated shaft described above, a car which can be moved in the longitudinal direction of the shaft, its guides and drive devices and an elevator platform for each floor.
  • the elevator system preferably already includes all doors and windows as well as a seal for attaching the shaft to the front of the building. Due to the inherent stability of the sheet metal box used for the prefabricated shaft, the elevator system according to the invention can be transported to the construction site in the prefabricated state by truck and set up there.
  • the method according to the invention for retrofitting a building with an elevator system according to the invention is intended for a building that contains a plurality of floors, which are in particular divided and have floor doors which are accessible via a common staircase.
  • the stairwell adjoins the front of the building and has a main landing for the floor doors and an intermediate landing for a two-flight staircase on each floor.

  • a foundation for the elevator system is being built in front of the front of the building. Regardless of the time, the front of the If the building is opened to the width of the stairwell, the intermediate landings and the two-flight staircase are removed, walkways are installed at the height of the main landings, which extend horizontally from the main landings to the front of the building and only partially, in particular half, the cross section of the stairwell to leave clear space for a staircase, and a single flight of stairs is installed, which connects the individual webs with each other and together forms a modified staircase.
  • the prefabricated elevator system is then transported from the factory to the construction site, placed on the foundation, aligned on it and thereby attached to the front of the building.
  • a connection is made between the elevator platforms and the webs of each floor, which is preferably designed to be floating in order to enable a small relative movement between the elevator system and the building.
  • access to the elevator platform on the ground floor is created from outside the building, preferably by attaching a front door to the metal box of the elevator shaft and attaching an external staircase in order to be able to reach the front door from the ground level.
  • the contact points between the elevator system and the front of the building are sealed, in particular with assembly foam and/or an elastomeric sealing element.
  • assembly foam and/or an elastomeric sealing element can be, for example, a U-profile or a hose that is filled with fire protection foam.
  • a casing for a shallow foundation is preferably made, in particular with a casing base of approx. 0.8 m to 1.0 m deep, in order to accommodate any supply lines, which are typically at a depth of approx .1.2 m are laid, not to be affected.
  • the foundation itself is preferably made as a foundation slab made of a one- or multi-part precast concrete part. This has the advantage that the foundation plate does not have to be concreted on site, but can be delivered ready by truck.
  • the foundation plate can be designed in several parts, with each prefabricated concrete part that is to become part of the foundation plate having dimensions and a weight that allow transport on a normal truck.
  • the foundation plate is preferably made from two prefabricated concrete parts that are not initially connected to one another. Only after the elevator system has been set up on the foundation are the two prefabricated concrete parts indirectly attached to one another by fixing the shaft of the elevator system partly on the first and partly on the second precast concrete part.
  • the single-flight staircase which connects the individual webs with each other and together forms a modified staircase
  • straight staircase sections with a quarter-turn entrance and exit, or with a quarter-turn landing at the entrance and exit are preferably used.
  • This shape of the stair sections makes the intermediate landings unnecessary;
  • the main landings are also preferably not part of the staircase, but rather just the webs connecting the individual staircase sections on the way up or down. This can be particularly advantageous when it comes to ensuring that the stairwell is completely barrier-free, as the main landings remain as purely maneuvering areas.
  • straight stair sections with only a quarter-turn entrance or exit can be used, whereby the Depending on the orientation of their slope, stair sections begin or end at the main landing or use the main landing as a quarter landing of the stairs.

  • the removal of the intermediate landings and the double-flight staircase as well as the installation of the webs and the single-flight staircase are carried out in sections successively from top to bottom, for example using a lifting platform.
  • the installation of the webs and the single-flight staircase is carried out by installing a pre-assembled staircase module.
  • This is not a step-by-step process, but rather the stairwell is first gutted by removing the intermediate landings and the two-flight staircase in order to be able to use the stairwell module in one piece.
  • the staircase module contains at least the webs and the stair sections, which connect the webs in one direction and preferably have a quarter-turn entrance and/or exit.
  • the staircase module contains, as an essential element, a holding structure to which the webs and the stair sections are attached and which preferably essentially consists of a number of interconnected profiles or tubes running in the stairwell and connecting all webs to one another.

  • the installation of the stairwell module becomes particularly easy if auxiliary rails for pushing the stairwell module into the building are attached at ground level and the stairwell module can be inserted through the open front of the building using the auxiliary rails. It is advisable to cover the foundation for the elevator system before attaching the auxiliary rails in order to avoid any damage to the foundation.
  • the auxiliary rails can be removed or cut to length, and the staircase module essentially rests on the supports of the basement staircase module.
  • the webs of the stairwell module can be connected to building walls and/or the main landings.

Rather, they can be used purely as traffic and maneuvering areas in the sense of complete accessibility. Appropriate railings ensure the necessary traffic safety.
  • the central function of the elevator platform 35 is made clear. Because this is the only way it is possible to find an escape route or to ensure access to the stairwell 5 without having to use the elevator system 26. Since the ground floor, which is half a floor above ground level 2, can only be reached at the same level via a walkway 24 from the front 1 of the building, an external staircase 32 must be provided, via which you can get from ground level 2 to walkway 24 can.
