Description

[0001] Procedure for installing an elevator system

[0002] The invention relates to a method for installing an elevator system according to the preamble of claim 1.

[0003] Installing an elevator system is complex and therefore associated with considerable costs. In particular, the construction of an elevator shaft for the elevator system, for example, during the construction of a building, and the subsequent installation of elevator components in the elevator shaft are quite complex. Typically, the elevator shaft is first constructed entirely within the building housing the elevator system, and then the elevator system, including its elevator components such as the elevator car, counterweight, drive motor, and guide rails, is installed in the elevator shaft. It has previously been proposed to construct the elevator shaft from several prefabricated shaft modules with shaft walls in which elevator components, such as guide rail sections, are at least partially pre-assembled.Prefabrication and preassembly do not take place on the construction site of the building housing the elevator, i.e., at the site where the elevator system is built, but in a factory and thus at the manufacturing site. This approach requires less time at the construction site. Furthermore, this procedure has a positive impact on the quality of the installation and the occupational safety of the installation personnel. A prefabricated shaft module encloses a hollow space in the form of a shaft, which can at least partially accommodate an elevator car. It is therefore very bulky, so that the transport of such shaft modules from the manufacturing site to the installation site can usually only be achieved with special transport. This makes transport very complex, time-consuming, and expensive.In addition, the transport is quite inefficient, since the hollow shaft spaces mentioned cannot be used to transport other parts and thus the capacity of the transporter cannot be used effectively.

[0004] DE 2755267 A1 describes, at least implicitly, a method for installing an elevator system with an elevator shaft. Various types of wall elements in the form of reinforced concrete slabs are provided at a manufacturing site. Four wall elements are assembled at the manufacturing site to form a shaft module enclosing a shaft space. Elevator components in the form of guide rail sections and one or two shaft doors are arranged in the shaft module and thus on the wall elements. The shaft module thus manufactured is transported to a manufacturing site of the elevator system, where it is assembled with other shaft modules to form an elevator shaft.

[0005] In contrast, the object of the invention is, in particular, to propose a method for installing an elevator system that enables simple and cost-effective installation. In particular, the aim is to enable simple, efficient, and cost-effective transport of prefabricated wall elements of an elevator shaft of the elevator system, equipped with elevator components, to the installation site of the elevator system. According to the invention, this object is achieved by a method having the features of claim 1.

[0006] The method according to the invention for installing an elevator system comprises the method steps of providing a wall element at a manufacturing site and arranging elevator components on the wall element at the manufacturing site. According to the invention, the method steps of transporting the wall element from the manufacturing site to a construction site of the elevator system and arranging the wall element are additionally carried out in such a way that the wall element, together with the walls of the elevator shaft, forms a shaft space of the vertically extending elevator shaft at the construction site, in which an elevator car of the elevator system can be relocatably arranged. The aforementioned method steps are carried out in the specified order.

[0007] In the method according to the invention, a shaft module enclosing a shaft space is not constructed from wall elements at the production site, as is known from DE 2755267 A1, and then transported to the production site. Instead, one, or in particular several, significantly more manageable wall elements that do not enclose a shaft space are transported from the production site to the production site, and only at the production site is an elevator shaft constructed using the wall element(s), in which an elevator car of the elevator system can be relocatably arranged. At the same time, the aforementioned advantage of prefabricated shaft modules remains: elevator components can be arranged on wall elements at the production site.

[0008] In addition to the above-mentioned method steps, the method comprises in particular the further method steps of providing an elevator car and optionally a counterweight and arranging the elevator car and optionally the counterweight in the elevator shaft such that the elevator car and optionally the counterweight can be displaced vertically in the elevator shaft.

[0009] In the following, directional specifications such as up, down, and sideways, or vertical and horizontal, refer to the orientation of the respective component in the elevator system's operating state. The operating state of the elevator system refers to the state after installation and commissioning of the elevator system. In the elevator system's operating state, people and / or goods can be transported in the elevator car between floors of the building housing the elevator system.

[0010] Provision of a wall element at the manufacturing site is understood here to mean that the wall element is manufactured at the manufacturing site or delivered to the manufacturing site. The wall element has, in particular, a cuboid basic shape and can, for example, be constructed primarily of reinforced concrete, wood, or metal, in particular steel.

[0011] At the manufacturing site, elevator components, particularly shaft material such as rail brackets, i.e., brackets and guide rail sections, are arranged on the wall element and thus fastened to the wall element. Additionally or alternatively, a drive motor or a shaft door can also be arranged on the wall element. The elevator components are in particular screwed directly or indirectly to the wall element. It is also possible for holders, brackets, or similar aids for connecting a wall element to a wall adjacent to the elevator shaft created with the wall element to be arranged on the wall element at the manufacturing site, or for these to be provided during the manufacture of the wall element, for example, by being cast in concrete.

[0012] To protect the components arranged on the wall element from damage and / or to enable or facilitate stacking of wall elements equipped with elevator components, additional components, such as wooden, Styrofoam, or plastic blocks, can be temporarily placed on the wall element. These components will be removed again as the installation of the elevator system continues at the installation site.

[0013] The wall element equipped with elevator components, in particular a plurality of wall elements, is transported by a suitable vehicle, in particular a truck, to the installation site of the elevator system, i.e., in particular, to a construction site of a building housing the elevator system. The transport takes place, in particular, partly via public roads. The installation site can also be in the immediate vicinity of the aforementioned construction site. In particular, several wall elements are stacked on top of each other on the corresponding vehicle, which enables efficient transport of the wall elements.

[0014] It is also possible for wall elements to be transported from more than one manufacturing site to the production site for further processing. This is particularly advantageous when different types of wall elements are used, allowing different manufacturing sites to specialize in providing different wall elements.

[0015] At the construction site, the elevator shaft of the elevator system is created using the wall element. The wall element is positioned, in particular by means of a crane, opposite the walls of the elevator shaft in such a way that, together with the aforementioned walls, it forms a shaft space. The wall element and the aforementioned walls thus also form a first, vertically extending section of the vertically extending elevator shaft. The aforementioned walls can also consist of a wall element that was provided with elevator components at a manufacturing site as described and then transported to the construction site. However, it is also possible for one or all of the aforementioned walls to be manufactured at the construction site, for example, cast with concrete.

[0016] The wall element is connected, in particular, to adjacent walls of the elevator shaft. For this purpose, appropriate brackets or other suitable connecting elements can be used. Connecting elements for connecting prefabricated components, such as concrete elements, are available in various designs on the market.

[0017] The elevator shaft of the elevator system can be designed so that a single elevator car can be moved vertically within a single travel path. However, it is also possible for the elevator shaft to be designed so that more than one, for example, two or three elevator cars can be moved vertically side by side and independently of each other. In this case, the elevator shaft has several travel paths arranged side by side.

[0018] The elevator shaft of the elevator system typically has a rectangular cross-section. However, it can also have a different shape.

[0019] In one embodiment of the invention, the wall element is constructed from various materials. The use of different materials allows the properties of the wall element to be particularly well adapted to the specific requirements. For example, the wall element can have a metal frame clad with wood, particularly a steel frame. In addition to the combination of wood and metal, other material combinations are possible.

[0020] In an embodiment of the invention, several wall elements, including different types of wall elements, are used to install the elevator system. For example, wall elements can be used to form side walls, rear walls, front walls, or partition walls of the elevator shaft. A wall element can also form a shaft ceiling. A partition wall is provided to separate two adjacent travel paths. With a wall element used to form a partition wall, elevator components, in particular guide rail sections, can be arranged on two opposite sides at the manufacturing site.

[0021] A side wall of the elevator shaft is understood here to be a wall on which a guide rail for guiding the elevator car is arranged when the elevator system is in operation. A side wall therefore does not have a door opening in which a shaft door is arranged when the elevator system is in operation. A front wall of the elevator shaft is understood here to be a wall with a door opening in which a shaft door is arranged when the elevator system is in operation. A rear wall of the elevator shaft is understood here to be a wall of the elevator shaft opposite a front wall. A rear wall can also have a door opening corresponding to the door opening of the front wall.

[0022] The various types of wall elements can have different heights, i.e., different vertical extensions. For example, the height of wall elements for forming side walls and / or partition walls can be matched to a standard length of guide rail sections. For example, guide rail sections available on the market in Europe are typically 2.5 or 5 m long. The height of wall elements for forming side walls and / or partition walls is then advantageously the same standard rail length or a multiple thereof, for example, 2.5, 5, 7.5, or 10 m. This advantageously allows the use of guide rails with standard lengths, which are more cost-effective than guide rails with different lengths.

[0023] The height of wall elements used to form front and / or rear walls can be adjusted to the floor height of the building housing the elevator system. The height of the wall element corresponds, in particular, to the floor height or a multiple of the floor height. For a floor height of 2.3 m, for example, the height of the wall element is 2.3, 4.6, or 6.9 m. The use of such wall elements to form front and / or rear walls enables particularly simple and therefore cost-effective installation of the elevator system.

[0024] In an embodiment of the invention, different types of wall elements are constructed from different materials. This allows the properties of a type of wall element to be particularly well adapted to its respective requirements. For example, wall elements for forming side walls and rear walls can be made of concrete, or at least primarily of concrete, and wall elements for forming front walls can be made of metal and / or wood, or at least primarily of metal and / or wood. It is also possible for wall elements for forming side walls and rear walls to be made of metal, or at least primarily of metal, and for wall elements for forming front walls to be made of wood, or at least primarily of wood.

[0025] In one embodiment of the invention, a shaft door, and in particular several shaft doors, are installed on the wall element at the manufacturing site. The installation of shaft doors is particularly time-consuming and, due to their height, poses risks in an existing elevator shaft. Installing one or more shaft doors on a wall element at the manufacturing site thus saves a significant amount of time and significantly reduces the risks for installation personnel at the installation site.

[0026] A wall element with one or more shaft doors forms a front or rear wall in the elevator shaft. The wall element can extend horizontally over one or more adjacent travel paths for an elevator car; thus, it can have one shaft door or several adjacent shaft doors. Vertically, it can extend over one floor or several floors; thus, it can have one shaft door or several adjacent shaft doors. The wall element can also have both adjacent and adjacent shaft doors.

[0027] In one embodiment of the invention, the wall element has a cavity that is filled with filler material at the construction site. The filler material, in particular, comprises concrete or is designed as concrete. This makes the wall element particularly lightweight, enabling particularly easy transport of the wall element from the manufacturing site to the construction site.

[0028] The wall element thus forms a so-called permanent formwork, which is only filled with the fill material, specifically concrete, at the construction site. The concrete is poured into the cavity of the wall element in liquid form and hardens around the wall element. The hardened concrete then assumes a structural function within the building housing the elevator system. The fill material can also be sand, insulation material, damping material, or soundproofing material. In this case, the fill material does not assume a structural function but merely has a functional purpose. In one embodiment of the invention, a section of the elevator shaft is constructed at the construction site from various types of wall elements and then placed on top of an existing section of the elevator shaft.This allows a shaft module to be constructed at the construction site from various types of wall elements, comparable to the shaft module described in DE 2755267 A1. This construction can be carried out independently of the existing section of the elevator shaft and, in particular, outside the building housing the elevator system. This makes the construction particularly efficient and safe, and allows for the construction of the constructed section to draw on existing experience with the installation of prefabricated shaft modules. This approach is particularly advantageous when the wall elements used to create a shaft module all have the same height.

[0029] As an alternative to the described construction of a shaft module from wall elements at the construction site, individual wall elements can also be arranged on or in an existing section of the elevator shaft and connected to the existing walls of the elevator shaft. This approach is particularly advantageous when the different types of wall elements have, at least in part, different heights.

[0030] In one embodiment of the invention, a basic module is delivered to the construction site as a shaft module enclosing a shaft space with pre-assembled elevator components and is arranged as the lowest shaft section of the elevator shaft. A particularly large number of elevator components must be installed in a shaft pit and thus in the aforementioned basic module. In particular, it may be necessary to also install elevator components on the floor of an elevator shaft, for example in the form of a buffer. The described embodiment of the basic module as a prefabricated shaft module allows the arrangement of a particularly large number of elevator components, which enables particularly efficient installation of the elevator system. The basic module can have a floor that forms the floor of the elevator shaft. It is also possible for the basic module to have special brackets protruding into the shaft space, on which elevator components can be arranged.In an embodiment of the invention, a top module is delivered to the construction site as a shaft module enclosing a shaft space with pre-assembled elevator components and is arranged as the uppermost shaft section of the elevator shaft. A particularly large number of elevator components must also be installed in a so-called shaft head and thus in the top module. In particular, it may be necessary to install elevator components on the ceiling of an elevator shaft, for example in the form of electronic components or suspension devices that are used for further installation or for later maintenance of the elevator system. The described embodiment of the top module as a prefabricated shaft module allows the arrangement of a particularly large number of elevator components, which enables particularly efficient installation of the elevator system. The top module can have a ceiling that forms the ceiling of the elevator shaft.It is also possible for the top module to have special brackets that extend into the shaft space, on which elevator components can be arranged.

[0031] However, it is also possible for the lowest and / or highest sections of the elevator shaft to be constructed from the wall elements described above. It is also possible for the lowest section, in particular, to be constructed entirely on site, especially by pouring concrete, and for the wall elements described above to be used on top of it.

[0032] In one embodiment of the invention, in addition to the wall element(s) provided with elevator components at the manufacturing site, a wall of the elevator shaft is constructed at the manufacturing site, and elevator components are subsequently arranged on this wall at the manufacturing site. The wall can, for example, be part of a supporting structure of the building housing the elevator system, which is advantageously used to form the elevator shaft. This allows the elevator shaft to be designed particularly effectively.

[0033] The wall in question is typically cast with concrete at the construction site. However, the wall can also be made of wood or metal. More than one wall of the elevator shaft, i.e., two or three walls, can also be constructed at the construction site. The wall elements described above, which were fitted with elevator components at the manufacturing site, are arranged on the wall(s). Individual wall elements can be arranged, or at least two wall elements can be connected together first and then arranged.

[0034] Further advantages, features, and details of the invention will become apparent from the following description of exemplary embodiments and from the drawings, in which identical or functionally identical elements are provided with identical reference numerals. The drawings are merely schematic and not to scale.

[0044] Fig. 9 a top view of an elevator shaft with three walls constructed at one location and a front wall consisting of a wall element.

[0045] According to Fig. 1, an elevator system 10 has an elevator shaft 12 for a three-story building, which in the present embodiment is composed of three shaft sections, in the form of a base module 14, an intermediate module 16, and a top module 18. Depending on the number of floors, the elevator shaft 12 can comprise further identically constructed intermediate modules 16. The wall elements (41, 43, 50; see Figs. 2, 3, 4, 7) forming the walls of said shaft modules 14, 16, 18 are prefabricated in a factory and thus at a production site and provided with elevator components. They are then brought to the construction site and thus transported to a production site of the elevator system 10. At the production site, the shaft sections are constructed from various types of wall elements and subsequently stacked on top of one another (see Fig. 2 and the associated description).

[0046] Each shaft module 14, 16, and 18 encloses a shaft space 15. The shaft modules 14, 16, and 18 are stacked on top of one another in such a way that the shaft spaces 15 of the shaft modules 14, 16, and 18 are vertically aligned and form the vertically extending elevator shaft 12, in which an elevator car 22 of the elevator system 10 is displaceably arranged. During displacement in the elevator shaft 12, the elevator car 22 is guided by guide rails (see 44 in Figs. 3 and 4) not shown in Fig. 1.

[0047] The elevator system 10 has a suspension element 24, the first end 26 of which is fixed in the top module 18. It then runs around the bottom of the elevator car 22 and is guided by a drive motor 28 arranged opposite the first end 26 of the suspension element 24 in the top module 18. From there, it runs through a suspension of a counterweight 30 to its second end 32, which is fixed in the area of ​​the drive motor 28. The drive motor 28 can move the suspension element 24 and thus the elevator car 22 in the elevator shaft 12. The elevator car 22 is connected via a suspension cable 34 to an elevator control system 36 arranged in the top module 18. The suspension cable 34 enables power supply and communication with the elevator car 22.

[0048] Fig. 2 shows how the intermediate module 16 is placed from above onto the first base module 14 by means of a crane 20. The base module 14 was previously placed in the same way onto a foundation of the elevator shaft 12 (not shown in detail). The base module 14 and the intermediate module 16 were previously assembled from wall elements at the construction site. The individual wall elements were transported from their construction site, i.e. from a factory, to the construction site and thus to the construction site by means of a truck (not shown). The wall elements were first prepared at the construction site, i.e. manufactured or delivered, and then provided with elevator components (not shown in Fig. 2), such as guide rail pieces, with which elevator components are arranged, in particular screwed, on the wall elements.

[0049] Fig. 2 also shows a top module 18 that has not yet been fully assembled. A side wall 40 of the top module 18 is formed by a wall element 41, to which a guide rail section (not shown in Fig. 2) (see 44 in Figs. 3 and 4) was arranged at the construction site. The side wall 40 of the top module 18 has already been connected to a rear wall 42 formed by a wall element 43. To complete the top module 18, a wall element forming a further side wall, a wall element forming a front wall with a shaft door, and a wall element forming a shaft ceiling are added. The aforementioned wall elements are thus arranged at the construction site in such a way that the wall elements, together with walls of the elevator shaft formed by wall elements, form a shaft space of the vertically extending elevator shaft only at the construction site.

[0050] After the intermediate module 16 has been placed in place as shown in Fig. 2 and the top module 18 has been completed, the top module 18 is placed onto the intermediate module 16 by means of the crane 20, thus closing the elevator shaft at the top.

[0051] It is also possible for the base module and / or the top module to be delivered to the installation site as pre-installed shaft modules and arranged as described.

[0052] The wall element 41 shown in Figs. 3 and 4 for forming a side wall consists of a reinforced concrete slab to which elevator components in the form of a guide rail section 44 and rail brackets 46 were arranged at the factory. The guide rail section 44 was fastened to the wall element 41 in a known manner by means of the rail brackets 46. In the finished elevator shaft 12, the guide rail section 44, together with the guide rail sections of other wall elements, forms a continuous guide rail for guiding the elevator car 22. The wall element 41 has a primarily cuboidal basic shape. In the area of ​​each of the four corners of the wall element 41, a holder 48 is cast in concrete, by means of which the wall element 41 can be connected to adjacent walls or wall elements of the elevator shaft.

[0053] It is also possible that the wall element forming a side wall consists of a wooden panel or a metal frame on which elevator components were arranged at the manufacturing site.

[0054] The wall element 49 shown in Figs. 5 and 6 for forming a partition wall between two adjacent travel paths, each for an elevator car, consists of a metal frame, in particular a steel frame, on which a guide rail section 44 was arranged on each side at the factory. The guide rail sections 44 were attached directly to the metal frame with brackets (not shown). In the area of ​​the four corners of the wall element 49, a holder 48 is welded, by means of which the wall element 49 can be connected to adjacent walls or wall elements. Wall elements for forming a partition wall do not have to consist of a metal frame; they can also be constructed, for example, from a reinforced concrete slab or from wood.

[0055] So-called omega brackets can also be installed on the wall elements forming a side wall or partition wall. An omega bracket is characterized by the fact that a travel path for a counterweight of the elevator system runs between the wall element and the omega bracket in the finished elevator shaft. An omega bracket also typically has three guide rails attached: two for guiding the counterweight and one for guiding the elevator car.

[0056] The wall element 50 shown in Fig. 7 forms a front wall in a shaft module. The wall element 50 can be made of concrete, wood, or metal. A shaft door 52 was arranged on the wall element 50 at the factory site. The shaft door 52 is attached to the wall element 50 by means of tabs and holders on the rear side of the wall element 50 and thus not visible. The wall element 54 shown in Fig. 8 also forms a front wall in a shaft module. Two shaft doors 52 were arranged side by side on the wall element 54 at the factory site. The wall element 54 thus extends over two side-by-side travel paths, each for an elevator car. The wall element 54 has a rectangular metal frame 56 to which a wooden paneling 58 is attached. The wall element 54 is thus constructed of metal and wood and is therefore made of different materials.

[0057] In addition to the metal and wood material combination, other material combinations are also possible. It is also possible for a wall element to have more than two landing doors arranged side by side, several landing doors arranged one below the other, or landing doors arranged both side by side and one below the other.

[0058] It is not necessary, as described above, for the wall elements delivered from the factory to the construction site to be first assembled into a shaft module, which is then placed on top of an existing section of the elevator shaft. Instead, the wall elements can be arranged individually on or in an existing section of the elevator shaft.

[0059] The various types of wall elements can have different heights. The height of a wall element forming a side wall can, in particular, correspond to the standard length of guide rails or a multiple thereof, for example, 2.5 or 5 m and multiples thereof. The height of a wall element forming a front or rear wall can, for example, correspond to the height of a floor of the building housing the elevator system or a multiple thereof.

[0060] Fig. 9 shows a top view of an elevator shaft 12 in which only one wall is formed from a wall element 60 delivered to the construction site and provided with elevator components at the factory. The other walls 62 were constructed using concrete at the construction site. After the walls 62 had been constructed, the wall element 60 was arranged on the walls using a crane. The wall element 60 has a cavity 64 which is filled with concrete after being arranged on the walls 62. The wall element 60 thus forms what is known as a permanent formwork. Elevator components (not shown) are also arranged on the walls 62, for example in the form of guide rail pieces. It is also possible for only one wall or two walls of the elevator shaft to be constructed at the construction site, and for the remaining walls to be formed from delivered wall elements.

[0061] Finally, it should be noted that terms such as "having," "comprising," etc., do not exclude other elements or steps, and terms such as "a" or "an" do not exclude a plurality. Furthermore, it should be noted that features or steps described with reference to one of the above embodiments may also be used in combination with other features or steps of other embodiments described above. Reference signs in the claims are not to be considered as limitations.
