Description

Technical Field

[0001] The invention relates to a method for installing an elevator installation according to the preamble of claim 1 . Background Art

[0002] The installation of an elevator system is complex and therefore associated with considerable costs. In particular, the construction of the elevator shaft for the elevator system, for example during building construction, and the subsequent installation of components in the elevator shaft are quite complex. Typically, the entire elevator shaft is first constructed inside the building housing the elevator system, and then the elevator system, along with its components (such as the elevator car, counterweight, drive, and guide rails), is installed in the elevator shaft. It has been proposed to construct the elevator shaft from a number of prefabricated shaft modules, into which the necessary components, such as guide rail segments, are at least partially preassembled. In this case, prefabrication and preassembly typically take place not at the construction site of the building housing the elevator, but rather in a factory. This method requires less time and has a positive impact on the quality of installation and the safety of the installers. After the individual shaft modules are assembled into the elevator shaft, the individual guide rail segments must be assembled into a continuous guide rail, with the individual guide rail segments, in particular, touching at their end faces so that they can be supported by the guide rail segments located directly below.

[0003] EP2559647A1 describes a method for installing an elevator system, in which a plurality of prefabricated shaft modules are provided. These shaft modules are stacked one on top of another so that the shaft spaces of the shaft modules are vertically aligned, forming a vertically extending shaft. In the elevator shaft thus formed, the elevator car of the elevator system is arranged so as to be vertically displaceable. After provision, each of the shaft modules has a guide rail segment, which together form a vertically extending guide rail for the elevator car within the elevator shaft formed by the shaft modules. The individual guide rail segments of the shaft modules extend from the associated shaft module after provision. Summary of the Invention

[0004] In contrast, the present invention is particularly directed to providing a method for installing an elevator system that allows for simple installation while minimizing the risk of damage to the components used during installation. This object is achieved according to the invention by a method having the features of claim 1.

[0005] The method for installing an elevator system according to the invention comprises at least the following method steps:

[0006] providing a plurality of shaft modules, wherein the shaft modules are prefabricated and are arranged to be placed one on top of the other, and wherein each shaft module encloses a shaft space, and

[0007] The shaft modules are placed one above the other in such a way that the shaft spaces of the shaft modules are oriented vertically and form a vertically extending elevator shaft in which an elevator car of the elevator system can be displaceably arranged.

[0008] The plurality of shaft modules comprises a base module and a first intermediate module, and optionally further intermediate modules, which are arranged to be placed on the base module. The height of the intermediate modules corresponds in particular to the floor height of the building housing the elevator system. Thus, an intermediate module is provided for each floor of the building. The height of the base module may deviate from the stated floor height.

[0009] After being provided, each of these shaft modules comprises at least one guide rail segment. In the elevator shaft formed from the shaft modules, the guide rail segments of the individual shaft modules form vertically extending guide rails for the elevator car. After being placed on the base module, the guide rail segments of the first intermediate module are displaced vertically downward to a certain extent until they rest on the guide rail segments of the base module. According to the present invention, the upper ends of the guide rail segments of the base module are arranged spaced downward from the upper edge of the base module.

[0010] The spacing of the upper ends of the guide rail segments of the base module relative to the upper edge of the base module advantageously allows for the placement of additional components on the base module after the base module has been provided and before the first intermediate module has been placed, i.e., before the elevator system is installed on the building housing the elevator system, without the risk of damaging the guide rail segments of the base module. This simplifies the handling of the base module and other components of the elevator system, such as the intermediate modules. Prior to the start of installation of the elevator system, these shaft modules can thus be easily temporarily stored, in particular stacked one on top of the other. The lowering of the guide rail segments of the first intermediate module allows for a simple, and therefore time-saving and cost-effective, assembly of the individual guide rail segments into guide rails.

[0011] The following directional specifications, such as top, bottom, and side or vertical and horizontal, refer to the orientation of individual components, particularly shaft modules or guide rail segments, when positioned one above the other. This orientation therefore corresponds to the orientation of the individual components in the operating state of the elevator system. The operating state of the elevator system is understood to mean the state after the installation and commissioning of the elevator system. Thus, in the operating state, people and / or goods can be transported in the elevator car of the elevator system between floors of the building housing the elevator system.

[0012] The shaft modules, and thus the guide rail segments, can be transported, for example, in an orientation different from the one described, from the factory where they are manufactured to the construction site of the building housing the elevator system. Initially, when the provided shafts are stacked one on top of the other, the base module is placed as the lowermost shaft module, particularly on the foundation of the building. Next, the first intermediate module, as the lowermost intermediate module forming the elevator shaft of the elevator system, is placed from above onto the base module. Further shaft modules, in the form of further intermediate modules or roof modules that close the elevator shaft upwards, are then installed on the respective uppermost intermediate modules until the elevator shaft reaches the desired height. The placement of the base module and the subsequent placement of the first intermediate module and any further shaft modules are typically accomplished using a crane.

[0013] The shaft modules can be delimited by shaft walls which can be made of concrete or wood, for example. However, the shaft modules can also be delimited by a carrier structure, in particular made of metal.

[0014] In particular, an elevator system may also include a counterweight, which is connected to the elevator car via a supporting mechanism, such as ropes or belts. During operation of the elevator system, the supporting mechanism, and thus the elevator car and counterweight, can be displaced within the elevator shaft, which is formed from the elevator shaft modules, by means of the elevator system's drive motor. The elevator system may also be devoid of a counterweight. In this case, the elevator car is in particular designed as a self-propelled elevator car, for example equipped with a friction wheel drive. In this case, the elevator system can also be designed as a so-called roller elevator.

[0015] The shaft modules are provided as described above and therefore already have at least one guide rail segment before the shaft modules are stacked. Therefore, when the shaft modules are provided, the guide rail segments are arranged in the individual shaft modules, in particular, fastened to the shaft walls of the shaft modules. After the shaft modules are stacked, the guide rail segments of the individual shaft modules are connected to one another so that together, the guide rail segments form a continuous, vertically extending guide rail for the elevator car in the elevator shaft formed by the shaft modules. The guide rail segments have an elongated shape and typically have a T-shaped profile.

[0016] The guide rail segment is fixed to the shaft wall or to a support defining the shaft module, in particular, by at least one, in particular at least two, so-called rail bows or brackets. The rail bow is in particular constructed in multiple parts, wherein a first rail bow part is fixed, for example screwed, to the shaft wall or the support, and a second rail bow part is connected to the guide rail segment by means of so-called rail clamps or rail clips. In this case, the guide rail segment is clamped in particular between the rail clamp and the second rail bow part. The first and second rail bow parts are screwed together, wherein the orientation of the two rail bow parts relative to each other can be varied in order to orient the guide rail segment. Different rail bows can be used. For example, so-called Z-brackets, L-brackets, or Ω-brackets can be used. The Ω-bracket is designed so that the displacement path of the counterweight of the elevator system extends between the inner side of the Ω-bracket and the side wall to which the Ω-bracket is fixed.

[0017] The elevator car and, if present, the counterweight of the elevator system are guided in particular by two opposing guide rails during displacement within the elevator shaft. Therefore, when providing shaft modules, two or four guide rail segments are arranged in each shaft module. In addition to the guide rail segments, other components of the elevator system may also be arranged in the shaft modules when providing shaft modules.

[0018] In the operating state of the elevator system, the guide rail segments of the base module are supported, in particular, on the floor of the elevator shaft and, therefore, in particular, on the foundation of the building housing the elevator system. The guide rail segments can thus be supported on the floor of the elevator shaft directly or indirectly via another component of the elevator system. The guide rail segments of the base module are, in particular, already arranged in their final position in the base module when the base module is provided, i.e., in the operating state of the elevator system. However, it is also possible to displace the guide rail segments vertically downwards after they have been placed on the foundation of the building until they are supported on the floor of the shaft.

[0019] The upper ends of the guide rail segments of the base module are spaced downward from the upper edge of the base module. Therefore, the guide rail segments of the base module do not protrude upward from the base module. In particular, the guide rail segments of the base module do not protrude downward from the base module. The spacing can be, for example, 0.5 to 5 cm, particularly 1 cm.

[0020] The elevator shaft of an elevator installation can be designed so that a single elevator car can be vertically displaced therein. However, the elevator shaft can also be designed so that more than one elevator car, for example two or three elevator cars, can be vertically displaced side by side and independently of one another. Thus, the elevator shaft can be designed as a so-called single shaft or as a multi-shaft structure. In the case of a multi-shaft structure, the shaft modules are particularly designed so that they can only be placed one above the other to form the elevator shaft, i.e., without being arranged side by side. However, it is also conceivable that the shaft modules can be arranged both side by side and one above the other to form the elevator shaft module.

[0021] In addition to the above-described method steps of providing and placing shaft modules one above the other, the method comprises in particular the further method steps of providing an elevator car and an optional counterweight, and arranging the elevator car and the optional counterweight in the elevator shaft such that the elevator car and the optional counterweight are vertically displaceable in the elevator shaft.

[0022] According to the present invention, before the aforementioned downward displacement of the guide rail segments of the first intermediate module, and therefore after the first intermediate module has been provided, the lower ends of the guide rail segments of the first intermediate module are spaced upward from the lower edge of the first intermediate module, and the upper ends of the guide rail segments of the first intermediate module are spaced downward from the upper edge of the first intermediate module. Consequently, the guide rail segments of the first intermediate module do not protrude upward or downward from the first intermediate module. The spacing can be, for example, 0.5 to 5 cm, in particular 1 cm. The spacing from the upper edge and the spacing from the lower edge can be the same or different. Consequently, the risk of the guide rail segments of the first intermediate module being damaged before or during placement on the base module is very low. Furthermore, handling of the first intermediate module is facilitated. Thus, before installation of the elevator system begins, the shaft modules can be easily temporarily stored, in particular stacked one on top of the other.

[0023] In the design of the present invention, when providing the first intermediate module, the guide rail segments of the first intermediate module are arranged in the first intermediate module so as to extend vertically. To ensure that the ends of the guide rail segments are spaced apart from the edges of the first intermediate module despite their vertical orientation, the length of the guide rail segments is less than the height of the first intermediate module. The vertical orientation of the guide rail segments advantageously ensures that, to form a continuous guide rail, the guide rail segments only need to be displaced vertically downward until they rest on the guide rail segments of the base module. This allows for particularly simple and therefore cost-effective installation of the elevator system.

[0024] As an alternative to the vertical orientation of the guide rail section of the first intermediate module, when providing the first intermediate module, the guide rail section of the first intermediate module can be arranged in the first intermediate module so that it is pivoted relative to the vertical direction and thus inclined relative to the vertical direction. The guide rail section of the first intermediate module then has, in particular, a length that is equal to the height of the first intermediate module.

[0025] To form a continuous guide rail, the guide rail segment is first pivoted so that it extends vertically and then shifted vertically downward until it rests on the guide rail segment of the base module. This arrangement of the guide rail segment of the first intermediate module, pivoted relative to the vertical, advantageously allows for a gap between the end of the guide rail segment and the edge of the first intermediate module, even when the length of the guide rail segment is equal to the height of the first intermediate module. This advantageously means that when stacking more than one intermediate module, the guide rail segment does not have to be shifted vertically further downward as the number of intermediate modules used to form the continuous guide rail increases.

[0026] In the design of the present invention, when a first intermediate module is provided, a connecting plate for connecting the guide rail segment of the first intermediate module to an adjacent guide rail segment is fixed to the end of the guide rail segment of the first intermediate module in such a manner that the connecting plate does not protrude beyond the end of the guide rail segment of the first intermediate module in the main extension direction of the guide rail segment of the first intermediate module. In the case of a longitudinally extending guide rail segment, the main extension direction of the guide rail segment is understood to be its longitudinal extension, that is, its extension in the vertical direction when the elevator system is in operation. The connecting plate preferably has a longitudinally extending square basic shape with a plurality of through holes or threaded holes. In order to prevent the connecting plate from protruding beyond the end of the guide rail segment, the connecting plate is fixed to the end of the guide rail segment in such a manner that the connecting plate does not extend outward from the end of the guide rail segment, but rather extends inward.

[0027] To form and secure a continuous guide rail, the guide rail segments of adjacent shaft modules are securely connected using connecting plates. These connecting plates are typically screwed to two adjacent guide rail segments. To achieve this, the connecting plates must protrude beyond the ends of the two guide rail segments. The screws used to connect the guide rail segments to the connecting plates extend through the through-holes or threaded holes in the connecting plates and align with the corresponding through-holes or threaded holes in the guide rail segments. Such connecting plates are commercially available in various embodiments.

[0028] The fixing of the connecting plate on the end of the guide rail section advantageously provides a connecting plate for connecting the guide rail sections at positions where the connecting plate is necessary after the shaft modules are placed one on top of the other. Therefore, the connecting plate does not have to be provided separately, which would cause additional expenditure and costs.

[0029] The connecting plate is fastened to the end of the guide rail segment in particular in such a way that, in order to connect the guide rail segment to the adjacent guide rail segment, it is first moved away from the end of the guide rail segment and subsequently connected to both guide rail segments. In the case of the described square basic shape of the connecting plate with through-holes or threaded holes, this means that the connecting plate is fastened, in particular screwed, to the end of the guide rail segment of the first intermediate module using the through-holes or threaded holes and, in the operating state of the elevator installation, is provided for connecting adjacent guide rail segments.

[0030] Alternatively, the connecting plate is fixed to the end of the guide rail segment so that the connecting plate can be pivoted relative to the end of the guide rail segment to connect the guide rail segment to an adjacent guide rail segment and subsequently to the adjacent guide rail segment. In the case of the described square basic shape of the connecting plate with through holes or threaded holes, this means that the connecting plate is fixed, in particular, screwed, to the end of the guide rail segment of the first intermediate module using only one of at least two through holes or threaded holes arranged adjacent to each other. In order to connect the guide rail segment of the first intermediate module to the adjacent guide rail segment, in particular, the fixing of the connecting plate, in particular the threaded connection to the guide rail segment of the first intermediate module, is loosened, and the connecting plate is then pivoted about the loosened connection to the position required for connecting to the adjacent guide rail segment. Finally, the connecting plate is connected, in particular, screwed, to the two adjacent guide rail segments using all through holes or threaded holes. When providing the first intermediate module, the connecting plate can also be fixed to the guide rail segment of the first intermediate module by additional connecting parts, which are loosened before the connecting plate is pivoted.

[0031] In the design of the present invention, a plurality of intermediate modules are provided and placed one on top of the other, wherein the intermediate modules are in particular designed to be identical. In this case, the first intermediate module is placed onto the base module as described above. The second intermediate module is placed onto the first intermediate module. This process is repeated until the uppermost intermediate module. After being placed onto the shaft module located below it, the guide rail sections of the individual intermediate modules are each shifted vertically downward until they are supported on the guide rail sections of the shaft module located below it. In this case, in particular, the aforementioned lowering process is first carried out at the guide rail section of the first intermediate module, followed by the guide rail section of the second intermediate module, and so on until the guide rail section of the uppermost intermediate module is reached.

[0032] In the embodiment of the invention, an additional guide rail segment is placed on top of the guide rail segment of the uppermost intermediate module. This is particularly advantageous when a plurality of intermediate modules are provided and placed one on top of the other, each having guide rail segments that are shorter than the height of the intermediate modules. With each intermediate module placed one above the other, the associated guide rail segment must be displaced further downwards until it can rest on the guide rail segment located below it. The additional guide rail segment serves to compensate for this displacement, i.e. a sufficiently long guide rail segment is also provided in the uppermost intermediate element, in this case a two-part guide rail segment. In particular, after the guide rail segment of the uppermost intermediate module has been displaced vertically downwards, the additional guide rail segment is placed downwards and on top of the guide rail segment of the uppermost intermediate module.

[0033] For example, when 20 intermediate modules are placed one above the other and the corresponding guide rail sections are 2 cm shorter than the height of the intermediate modules, the guide rail section of the uppermost intermediate module needs to be displaced 40 cm downwards. Thus, the additional guide rail section advantageously has a length of 40 cm.

[0034] In the design solution of the present invention, a top module is provided as another shaft module, which is mounted on the topmost intermediate module. As a result, the elevator shaft is closed upward. After provision, the top module also has guide rail sections, which, after being placed on the topmost intermediate module, are displaced vertically downward to form guide rails for the elevator car. The guide rail sections of the top module are particularly displaced vertically downward until they are supported from above on the guide rail sections of the topmost intermediate module or, when additional guide rail sections are provided, on additional guide rail sections. When providing the top module, the drive motor and other components of the elevator system are particularly arranged in the top module. The top module can be implemented, for example, as the top module described in WO 2022 / 233803 A1.

[0035] The lower end of the guide rail section of the roof module is in particular at a vertical distance upward from the lower edge of the roof module.

[0036] It is also possible that the top module, which closes the elevator shaft at the top, has no guide rail sections, the top module thus forming a kind of machine room.

[0037] If additional guide rail segments are provided, they are arranged in the top module, particularly when the top module is provided. Advantageously, the additional guide rail segments do not need to be transported and provided separately, but rather are transported and provided in the top module. Arranging the additional guide rail segments in the top module also has the advantage that the top module can be placed onto the uppermost intermediate module, and the additional guide rail segments are thus provided where needed.

[0049] according to Figure 1 The elevator installation 10 includes an elevator shaft 12 for a three-story building. In this embodiment, the elevator shaft consists of three shaft modules: a base module 14, a first intermediate module 16, and a top module 18. Depending on the number of floors, the elevator shaft 12 may also include an intermediate module 16. The shaft modules 14, 16, and 18 are prefabricated in a factory and equipped with elevator components. They are then brought to the construction site and stacked one on top of the other. This process of prefabricating, arranging the elevator components, and transporting the shaft modules 14, 16, and 18 can be referred to as providing the shaft modules 14, 16, and 18.

[0050] Each shaft module 14, 16 and 18 encloses a shaft space 15. The shaft modules 14, 16, 18 are stacked in such a way that the shaft spaces 15 of the shaft modules 15, 16, 18 are oriented vertically and form a vertically extending shaft 12 in which the elevator car 22 of the elevator system 10 is displaceably arranged.

[0051] exist Figure 2 1 shows how the top module 18 is placed from above onto the first intermediate module 16 using a crane 20. The first intermediate module 16 is already mounted in the same manner on the base module 14. The base module 14 rests on a foundation (not shown in detail) of the elevator shaft 12. The base module 14 and the first intermediate module 16 form an upwardly open, not yet completed elevator shaft, which is closed upwardly by placing the top module 18.

[0052] also, Figure 1 The elevator system 10 has an elevator car 22 which can be moved along the elevator shaft 12 in the Figure 1 The guide rails not shown in Figure 4 66 in the top module). To this end, the elevator system 10 has a support mechanism 24, whose first end 26 is fixed in the top module 18. The support mechanism then extends around the elevator car 22 at the bottom and is guided by a drive motor 28 arranged in the top module 18 opposite the first end 26 of the support mechanism 24. From there, the support mechanism extends through the suspension of the 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 support mechanism 24, and thus the elevator car 22, in the elevator shaft 12. The elevator car 22 is connected to an elevator control 36 arranged in the top module 18 via a suspension cable 34. The suspension cable 34 enables power supply and communication to the elevator car 22.

[0053] The individual shaft modules can be delimited by shaft walls, which can be made of concrete or wood, for example. However, it is also possible for the shaft modules to be delimited by a carrier structure, in particular made of metal. The elevator shaft can also have more than one intermediate module, wherein the individual intermediate modules are in particular constructed identically.

[0054] according to Figure 3 The elevator shaft 12 consists of a base module 14, a first intermediate module 16, two further intermediate modules 17, and a top module 18, i.e., a total of five shaft modules. When providing the shaft modules 14, 16, 17, 18, a guide rail segment 40 is arranged in each shaft module 14, 16, 17, 18. The guide rail segments 40 are screwed to the wall of the respective shaft module, in particular, by means of rail bows (not shown). The following describes a method using only one guide rail segment per shaft module. Two guide rail segments for guiding the elevator car 22 and two guide rail segments for guiding the counterweight 30 are provided in each shaft module. The method for all guide rail segments is similar to the method described below using a single guide rail segment.

[0055] The guide rail segments 40 of the basic module 14 are arranged in the basic module 14 in such a way that the lower ends 42 of the guide rail segments 40 of the basic module 14 terminate flush with the lower edge 44 of the basic module 14. As a result, the guide rail segments 40 of the basic module 14 can be supported on the floor of the elevator shaft 12. It is also possible to connect at least one plate and / or at least one lining to the lower end of the guide rail segment of the basic module, which plate and / or lining terminate flush with the lower edge of the basic module.

[0056] The upper end 46 of the guide rail section 40 of the basic module 14 is arranged spaced downward from the upper edge 48 of the basic module 14. Therefore, the guide rail section 40 of the basic module 14 ends below the upper edge 48 of the basic module 14. A connecting plate 50 is arranged on the upper end 46 of the guide rail section 40 of the basic module 14 to connect the connecting plate 50 to the upper edge 48 of the basic module 14. Figures 5 to 7 The connecting plate 50 is fastened to the guide rail section 40 of the basic module 14 such that it does not project beyond the upper end 46 of the guide rail section 40 of the basic module 14 in the main extension direction of the guide rail section and therefore in the vertical direction.

[0057] The rail segment 40 of the first intermediate module 16 placed on the base module 14 is arranged above the rail segment 40 of the base module 14. The rail segment 40 of the first intermediate module 16 is arranged in the intermediate module 16 such that the lower end 52 of the rail segment 40 of the first intermediate module 16 is spaced upward from the lower edge 52 of the intermediate module 16. The rail segment 40 of the first intermediate module 16 thus ends above the lower edge 52 of the first intermediate module 16. The upper end 56 of the rail segment 40 of the first intermediate module 16 is arranged spaced downward from the upper edge 58 of the first intermediate module 16. The rail segment 40 of the first intermediate module 16 thus ends below the upper edge 58 of the first intermediate module 16. A connecting plate 50 is arranged at the upper end 54 of the rail segment 40 of the first intermediate module 16, similar to the arrangement at the upper end 46 of the rail segment 40 of the base module 14.

[0058] Two further intermediate modules 17 arranged above the first intermediate module 16 are designed identically to the first intermediate module 16 .

[0059] A guide rail section 40 is also arranged in the top module 18, whose lower end 60 is arranged spaced upward from the lower edge 62 of the top module 18. The drive mechanism 28 is supported from above on the guide rail section 40 of the top module 18. In addition, an additional guide rail section 64 with a connecting plate 50 is arranged in the top module 18, laterally offset relative to the guide rail section 40 of the top module 18.

[0060] exist Figure 3 In the example described in FIG, the base module 14 is higher than the intermediate modules 16, 17 to form a shaft bottom pit. However, it is also possible that Figure 3 The base module is replaced by a combination of the lower base module and the first intermediate module.

[0061] from Figure 3, for further installation, the guide rail segment 40 of the first intermediate module 16 is first displaced vertically downward until it rests on the guide rail segment 40 of the base module 14, i.e., until the lower end 52 of the guide rail segment 40 of the first intermediate module 16 contacts the upper end 46 of the guide rail segment 40 of the base module 14. Subsequently, the lower end 52 of the guide rail segment 40 of the first intermediate module 16 and the upper end 46 of the guide rail segment 40 of the base module 14 are connected by means of a connecting plate 50 arranged on the guide rail segment 40 of the base module 16.

[0062] The described discharge and connection are repeated using the guide rail segment 40 of another intermediate module 17. The additional guide rail segment 64 is then separated from the top module 18 and arranged above the guide rail segment 40 of the uppermost intermediate module 17 and connected thereto. The length of the additional guide rail segment 64 is selected here so that the gap between the guide rail segment 40 of the uppermost intermediate module 17 and the guide rail segment 40 of the top module 18 is almost closed. After the additional guide rail segment 64 has been arranged, the guide rail segment 40 of the top module 18 is lowered until it is supported from above on the additional guide rail segment 64. Finally, the guide rail segment 40 of the top module 16 and the additional guide rail segment 64 are connected to the connecting plate 50 previously arranged in the top module 16. The state thus achieved is Figure 4 In this state, the guide rail segments 40 of the shaft modules 14 , 16 , 17 and 18 together with the additional guide rail segment 64 form a vertically extending guide rail 66 for the elevator car 22 .

[0063] according to Figure 5 , the connecting plate 50 has a total of eight first through-holes 68. The connecting plate can also have threaded holes instead of through-holes. When providing a shaft module with a guide rail segment 40, the connecting plate 50 is fixed at the upper end of the guide rail segment 40 in such a way that the connecting plate 50 does not protrude upwards beyond the guide rail segment 40. The guide rail segment 40 has four second through-holes 70 at its ends. The first and second through-holes 68, 70 are arranged so that the connecting plate 50 can be arranged on the guide rail segment 40 in such a way that the first and second through-holes 68, 70 are aligned and the screws 72 can be inserted through the through-holes 68, 70. Figure 5 The connecting plate 50 is fixed to the Figure 5 On the lower guide rail section 40.

[0064] In combination Figure 3 and Figure 4After the guide rail section 40 is lowered as described, the two screws 72 are loosened and the connecting plate 50 is thereby loosened from the lower guide rail section 40. Then, the connecting plate 50 is pushed upward along the lower guide rail section and the upper guide rail section 40 until the four upper through holes 68 of the connecting plate 50 are aligned with the four through holes 70 of the upper guide rail section 40, and the four lower through holes 68 of the connecting plate 50 are aligned with the four through holes 70 of the lower guide rail section 40. Subsequently, the screws 72 are inserted through all the through holes 68 and 70 and the connecting plate 50 is tightened to the guide rail section 40. This state is Figure 6 Shown in.

[0065] Figure 7 The connection plate 50 is shown on the guide rail section 40 when providing the shaft module. Figure 5 The connecting plate 50 is connected to the lower rail section 40 by only one screw 72. Here, the one screw 72 is selected and arranged in such a way that it is already arranged at the location where it is also located after the connection with the upper rail section 40. After the upper rail section 40 is lowered, only this one screw 72 needs to be loosened and the connecting plate 50 is pivoted about this one screw 72. Figure 6 The connecting plate 50 can then be screwed to the two guide rail sections 40 as described above.

[0066] Figure 8 The elevator shaft 12 is shown with Figure 8 The differences between the elevator shafts shown lie primarily in the arrangement of the guide rail segments 40 in the intermediate modules 16, 17, so only the differences between these two elevator shafts will be discussed. The guide rail segments 40 of the intermediate modules 16, 17 are not as Figure 3 The guide rail segments 40 of the intermediate modules 16 and 17 do not extend in the vertical direction as in the example, but are arranged pivotally relative to the vertical direction. The length of the guide rail segments 40 of the intermediate modules 16 and 17 is equal to the height of the intermediate modules 16 and 17. The guide rail segments 40 of the intermediate modules 16 and 17 are pivoted relative to the vertical direction to such an extent that their ends are arranged spaced apart from the edges of the respective intermediate modules above and below.

[0067] Based on the length of the guide rail segments 40 of the intermediate modules 16, 17, Figure 3 Unlike the situation in , no additional guide rail segments are required. The guide rail segments 40 of the top module 18 can be displaced downwards to the extent that they rest on the guide rail segments 40 of the uppermost intermediate module 17. Figure 9 Shown in.

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 within the scope of the appended claims.
