Description

[0001] Shaft module for forming an elevator shaft for an elevator system composed of stacked shaft modules

[0002] The invention relates to a shaft module for forming an elevator shaft for an elevator system composed of stacked shaft modules according to the preamble of claim 1.

[0003] The construction of an elevator shaft for an elevator system, for example, during the construction of a building and the subsequent installation of the elevator system, is complex and therefore associated with considerable costs. Typically, the elevator shaft is constructed first, followed by the installation of the elevator system with its components such as the cabin, counterweight, drive motor, and guide rails. It has been proposed to construct the elevator shaft from several prefabricated modules in which necessary components, such as shaft doors, are already pre-assembled. Prefabrication and pre-assembly are typically carried out in a factory. This approach requires less time on site. It also has a positive impact on the quality of the installation and the occupational safety of the installation personnel.

[0004] The applicant's unpublished international application with application number PCT / EP2022 / 061744 describes a shaft module and a method for placing a shaft module on an underlying shaft module to form an elevator shaft of an elevator system. In a transport state of the shaft module, a door threshold of the shaft door is fixed to the shaft module by means of a temporary door holder. After placing the shaft module on an underlying shaft module, the shaft module is brought from its transport state into an operating state. The temporary door holder is replaced by a permanent door holder fixed to the underlying shaft module.

[0005] One object of the invention is, in particular, to propose a shaft module for forming an elevator shaft for an elevator system composed of stacked shaft modules, which allows for the most extensive possible preparatory work on the shaft module and thus facilitates simple installation of the elevator system. According to the invention, this object is achieved with a shaft module having the features of claim 1.

[0006] The shaft module according to the invention for forming an elevator shaft for an elevator system composed of stacked shaft modules comprises a first side wall with a door opening, a second side wall adjoining the first side wall at an angle other than 180°, and a shaft door arranged in the door opening with a door sill. According to the invention, the door sill of the shaft door is fixed to the second side wall by means of a final door sill bracket. Fixing the door sill to the second side wall by means of the final door sill bracket enables the door sill to be fixed in place so that it can remain on the shaft module after the shaft module has been placed on an underlying shaft module and thus does not need to be replaced or modified. The door sill can thus be permanently fixed in the shaft module during the manufacture of the shaft module, i.e., in particular in a factory, without the need for any rework.

[0007] Fixing the door threshold with a final door threshold bracket to the second side wall is particularly advantageous for shaft modules where the door opening in the first side wall is open at the bottom, meaning the first side wall has no horizontal section below the door opening. In this case, the door threshold of the shaft door cannot be fixed to the first side wall as is usually the case.

[0008] The shaft module according to the invention is particularly intended to be placed on an underlying shaft module during the formation or construction of an elevator shaft. The location or direction references used here, such as "bottom," "top," "vertical," or "horizontal," always refer to the orientation of the shaft module in its operating state, i.e., when it forms part of the elevator shaft after its assembly.

[0009] The shaft module, at least with respect to the aforementioned side walls, can, for example, be made primarily of concrete, in particular reinforced concrete, wood, or metal, in particular metal profiles. In the case of a concrete construction, the shaft module can have a so-called permanent formwork, i.e., a formwork that is not removed after the concrete has hardened.

[0010] The shaft module can be designed as a so-called top module or as a so-called base module. A top module closes off an elevator shaft at the top. It contains a top module ceiling, which acts as the shaft ceiling and closes off the elevator shaft at the top. A top module can house a drive motor for moving a car during operation of the elevator system. Several base modules are arranged below a top module, which, together with the top module, form the elevator shaft. The shaft modules are designed so that they can be placed onto a shaft module below, for example, using a crane.

[0011] The shaft module can also have more than one side wall with a door opening. In particular, it is possible for two opposite side walls to each have a door opening.

[0012] The second side wall adjoins the first side wall, in particular, at an angle of 90°. The shaft module, and thus also the elevator shaft encompassing this shaft module, has a rectangular cross-section. However, it can also have a different cross-section. The cross-section can, for example, be round or oval, allowing the transition from the first side wall to the second side wall to be defined largely freely.

[0013] The door threshold runs horizontally, closes off the shaft door at the bottom, and thus extends at least almost across the entire width of the door opening of the first side wall. It is designed, in particular, as a flat rail, elongated in a main direction of extension, particularly made of metal. When the elevator system is in operation, the door threshold covers, in particular, a joint extending in said main direction of extension between the elevator shaft and a floor adjacent to the elevator shaft of a floor of the building containing the elevator shaft.

[0014] The term "fixing the door threshold using a final door threshold bracket" refers to the fact that the fixing of the door threshold made before the shaft module is installed is not, or does not need to be, loosened or removed after it has been installed on a shaft module below. However, it is entirely possible that the position of the final door threshold bracket, and thus also of the door threshold, may be slightly altered after it has been installed on a shaft module below. This allows the door threshold to be aligned or adjusted.

[0015] It is also possible to reinforce the door sill's fixation after it has been placed on an underlying shaft module. For example, the door sill can be fixed to the underlying shaft module with additional brackets without loosening or removing the existing final door sill bracket.

[0016] A feature of the final door threshold bracket is that it has a supporting function in fixing the door threshold to the second side wall and thus to the shaft module both in a transport state of the shaft module and in an operating state of the shaft module, i.e. during operation of the elevator system.

[0017] The operation of an elevator system is understood here to mean that the elevator car is moved in the elevator shaft and, in particular, that people and / or goods are transported in the car.

[0018] The shaft module is typically prepared for transport in a factory. The side walls and, if necessary, a shaft module ceiling are constructed, and the shaft door is positioned in the doorway, thus closing the shaft opening. Additional elevator components, such as guide rail sections or a drive motor for the elevator system, can also be installed on the shaft module. The shaft module is then transported to the construction site where the elevator system, and thus the elevator shaft, is to be erected. The shaft module is placed onto a shaft module below it while the shaft module is still in its transport state. During the further installation process, the shaft module is then converted from transport to its operating state.It is possible for a shaft module to be brought into operation immediately after it has been installed, or for all the shaft modules forming the elevator shaft to be placed on top of one another first and only then for the individual shaft modules to be brought into their operating state.

[0019] In one embodiment of the invention, a third side wall, opposite the second side wall, adjoins the first side wall. The door sill of the shaft door is then also fixed to the third side wall by means of the final door sill bracket. This enables particularly simple and cost-effective fixing of the door sill.

[0020] The door sill bracket thus extends between the second and third side walls. The third side wall also adjoins the first side wall at a 90° angle, so that the third side wall runs parallel to the second side wall.

[0021] It is also possible for the first side wall to have more than one door opening, each of which houses a shaft door. In this case, several elevator cars can travel side by side in the shaft formed by the shaft modules. In this case, the door threshold bracket can also extend between the second and third side walls and fix several adjacent door thresholds to the second and third side walls.However, it is also possible that intermediate supports, such as a projection running vertically inwards into the elevator shaft or horizontally running supports, for example in the form of so-called dividing bars or divider beams, are arranged between the door openings of the first side wall and the individual door thresholds are fixed by means of door threshold supports to the second side wall and an intermediate support, to the third side wall and an intermediate support or to two intermediate supports.

[0022] In one embodiment of the invention, the final door threshold bracket comprises a first wall bracket attached to the second side wall, a second wall bracket attached to the third side wall, and a door threshold support supported by the first wall bracket and the second wall bracket. This enables simple yet stable fixation of the door threshold. The use of a door threshold support advantageously allows for the use of a standard door threshold, which can also be used in a conventionally manufactured elevator shaft, i.e., one not consisting of prefabricated shaft modules. Such standard door thresholds are available in a wide range and at reasonable prices on the market.

[0023] The two wall brackets are, in particular, primarily L-shaped with one vertical and one horizontal leg and are, in particular, screwed to the second and third side walls, respectively. They are, in particular, identical or of the same design and, in particular, made of metal.

[0024] The door sill support rests on the two wall brackets and is thus supported from above by the wall brackets. The door sill support is connected, in particular, to the wall brackets, in particular by screwing. The door sill rests on the door sill support and is thus supported from above by the door sill support. The door sill is connected, in particular, to the door sill support, for example, by screwing.

[0025] In one embodiment of the invention, the first wall bracket and the second wall bracket are designed and attached to the second side wall and the third side wall, respectively, such that their position on the second side wall and the third side wall, respectively, can be adjusted together with the door sill support. For this purpose, the first wall bracket has a first adjustment arrangement, and the second wall bracket has a second adjustment arrangement. This advantageously enables adjustment of the door sill bracket and thus the door sill after the shaft module has been placed on a shaft module below it, without the door sill bracket having to be loosened or removed.

[0026] In particular, the wall brackets each have an elongated hole as an adjustment arrangement, through which a screw or bolt protrudes for fixing to the second or third side wall. The elongated hole thus allows the position of the wall bracket relative to the screw or bolt, and thus relative to the second or third side wall, to be changed after loosening the screw or a nut screwed onto the bolt.

[0027] It is particularly possible for the position of the wall brackets on the second or third side wall to be changed in the vertical direction. The aforementioned elongated hole in a wall bracket thus runs particularly vertically. In an embodiment of the invention, the first wall bracket, the second wall bracket, and the door sill support are designed such that the position of the door sill support can be changed relative to the first wall bracket attached to the second side wall and relative to the second wall bracket attached to the third side wall. For this purpose, the first wall bracket, the second wall bracket, and / or the door sill support have suitable adjustment arrangements. This advantageously enables further adjustment of the door sill bracket and thus of the door sill after the shaft module has been placed on an underlying shaft module, without the door sill bracket having to be loosened or removed.

[0028] The change in the position of the door sill support relative to the wall brackets attached to the side walls can occur, in particular, along a main extension direction of the door sill support or transversely to the aforementioned main extension direction of the door sill support. The main extension direction of the door sill support runs between the first and second wall brackets, i.e., parallel to the first side wall between the second and third side walls.

[0029] For this purpose, the door sill support has, for example, a so-called first T-slot as an adjustment arrangement, which is open downwards in the direction of the horizontally running leg of the first wall bracket and runs transversely to the main extension direction or in the main extension direction of the door sill support. A head of a screw or a so-called sliding nut can be arranged in the first T-slot, the position of which in the first T-slot can be changed in the direction of the first T-slot. In this case, the first wall bracket has in particular one or more through holes in its horizontally running leg, which are aligned with the first T-slot of the door sill support. This allows the aforementioned screw or a screw that can be screwed into the sliding nut to protrude through a through hole and, if necessary, together with a nut, to clamp the door sill support against the first wall bracket.The same applies to the connection of the door sill support with the second wall angle.

[0030] Additionally or alternatively, the above-described through-hole of the first wall bracket can have a diameter that is larger than the diameter of the screw protruding through the through-hole as an adjustment arrangement for the first wall bracket. This allows the position of the door sill support to be adjusted transversely to the direction of the first T-slot. Alternatively or additionally, it is possible for the head of the screw or the sliding nut arranged in the first T-slot to be moved relative to the door sill support transversely to the direction of the first T-slot. The same applies to the connection of the door sill support to the second wall bracket. However, other technical implementations are also possible.

[0031] In an embodiment of the invention, the door sill support and the door sill are designed and connected to each other in such a way that the position of the door sill relative to the door sill support can be adjusted. For this purpose, the door sill support and / or the door sill have suitable adjustment arrangements. This advantageously enables further adjustment of the door sill support and thus the door sill after the shaft module has been placed on a shaft module below it, without the door sill support having to be loosened or removed.

[0032] The change in the position of the door sill relative to the door sill support can take place in particular along the main extension direction of the door sill support or transversely to the said main extension direction of the door sill support.

[0033] For this purpose, the door sill has, for example, a second T-slot as an adjustment arrangement, which is open towards the door sill support and runs in the main direction of extension or transversely to the main direction of extension of the door sill support. A head of a screw or a so-called sliding nut can be arranged in the second T-slot, the position of which in the second T-slot can be changed in the direction of extension of the second T-slot. In this case, the door sill support has in particular one or more through holes which are aligned with the second T-slot of the door sill. This allows the above-mentioned screw or a screw which can be screwed into the sliding nut to protrude through a through hole and, if necessary, together with a nut, clamp the door sill against the door sill holder. However, other technical implementations are also possible.Additionally or alternatively, the above-described through-hole in the door sill support can, for example, serve as an adjustment device for the door sill support, have a diameter that is larger than the diameter of the screw protruding through the through-hole. This allows the position of the door sill relative to the door sill support to be adjusted transversely to the direction of the second T-slot. Alternatively or additionally, it is possible for the head of the screw or the sliding nut arranged in the second T-slot to be moved transversely to the direction of the second T-slot relative to the door sill. However, other technical implementations are also possible.

[0034] In one embodiment of the invention, the shaft door of the shaft module is secured to the shaft module by means of an upper door support module. The shaft door is thus secured to the shaft module via the door sill and the final door sill support, as well as additionally by means of the upper door support module. This enables a particularly stable fixation of the shaft door in the shaft module.

[0035] The upper door support module, in particular, allows the vertical position of the landing door to be adjusted within certain limits. For this purpose, it features elongated holes, for example, that allow vertical adjustment.

[0036] In one embodiment of the invention, the shaft door has movable door segments for closing and opening the shaft door. These segments are secured against movement by a transport lock when the shaft module is in transport. This prevents damage to the door segments due to uncontrolled movements. The door segments are secured, in particular, in their open position. This advantageously makes the shaft module accessible in its transport state, which is helpful during transport and when placing it on an underlying shaft module. Furthermore, the door segments are protected against distortion or deformation during transport of the shaft module.

[0037] The shaft module is, for example, in its transport state before being placed on a shaft module below it. The transport lock comprises, in particular, a securing bracket which is attached to the second side wall and secures the door segments in their open position. This makes the transport lock particularly simple and cost-effective to implement. The transport lock can, for example, consist of one or two Z-shaped brackets or a U-shaped bracket made of wood or metal, which are screwed to the second side wall and engage around the door segments so that they hold the door segments in their open position. The shaft door can have door segments which are moved in the same direction to open the shaft door. In this case, the door segments are secured relative to the second side wall.The landing door can also have door segments that slide in opposite directions to open the landing door. In this case, one door segment is secured against the second side wall and another door segment is secured against the third side wall.

[0038] 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 equivalent elements are provided with identical reference numerals. The drawings are merely schematic and not to scale.

[0044] Fig. 6 a section through the door sill and the door sill support transverse to the main extension direction of the door sill support.

[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 a first base module 14, a second base module 16, and a top module 18. Depending on the number of floors, the elevator shaft 12 can comprise additional second base modules 16. The aforementioned shaft modules 14, 16, 18 are prefabricated in a factory and equipped with elevator components. They are then brought to the construction site and stacked on top of one another. The shaft modules 14, 16, 18 all have a primarily cuboidal basic shape. They are constructed primarily from wood. Of course, other materials such as concrete are also conceivable.

[0046] Fig. 2 shows how the top module 18 is placed onto the second base module 16 from above by means of a crane 20. The second base module 16 was previously placed onto the first base module 14 in the same way. The base module 14 stands on a foundation of the elevator shaft 12 (not shown in detail). The base modules 14, 16 form an upwardly open, not yet finished elevator shaft, which is closed off at the top by the placement of the top module 18.

[0047] The elevator system 10 according to Fig. 1 also has a car 22 that can be moved vertically along guide rails (not shown) in the elevator shaft 12. For this purpose, 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 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 region of the drive motor 28. The drive motor 28 can move the suspension element 24 and thus the car 22 in the elevator shaft 12.

[0048] According to Fig. 3, the second basic module 16, i.e., a shaft module for forming an elevator shaft 12 of an elevator system 10, has a first side wall 34 with a downwardly open door opening 36. The first side wall 34 thus has the shape of an inverted "U." In the illustration in Fig. 3, a second side wall 38 on the left side and a third side wall 40 on the right side adjoin the first side wall 34, each at an angle of 90°, i.e., not equal to 180°.

[0049] A shaft door 42 is arranged in the door opening 36. The first base module 14 and the top module 18 can be constructed, at least with respect to the shaft door, similarly to the second base module 16 described in detail below. The shaft door 42 is secured, among other things, by means of an upper door support module 44. The upper door support module 44 has three metal tongues 48 by means of which an upper, horizontally extending part of a door frame 50, a so-called door jamb 52, is screwed to a cross member 54 of the first side wall 34. Since the metal tongues 48 are arranged behind the door jamb 52 and the cross member 54 in Fig. 3, they are shown in dashed lines.

[0050] The shaft door 42 has a horizontally extending door sill 64, which closes off the shaft door 42 at the bottom. It extends across almost the entire width of the door opening 36 of the first side wall 34 and is designed as a flat, elongated rail, particularly made of metal, extending in a main extension direction 65 of the door sill 64.

[0051] The door sill 64 is fixed or secured to the second side wall 38 and the third side wall 40, and thus to the shaft module 16, by a final door sill bracket 46. The door sill bracket 46 has a first wall bracket 56 with two perpendicularly arranged legs. A vertically extending leg (57 in Figs. 4 and 5) of the first wall bracket 56 is screwed to the second side wall 38.

[0052] A second wall bracket 59, identical to the first wall bracket 56, is screwed to the third side wall 40 at the same height as the first wall bracket 56. A door sill support 62 of the final door sill bracket 46, which consists primarily of a metal profile, runs between the second side wall 38 and the third side wall 40. The door sill support 62 thus also extends in the main extension direction 65 of the door sill 64. The door sill support 62 rests at both ends on the horizontally extending legs (61 in Figs. 4 and 5) and is thus supported on the two wall brackets 56, 59. The door threshold 64 rests on the door threshold support 62 and, during operation of the elevator system 10, serves, among other things, to guide movable door segments of the shaft door 42, not visible in Fig. 3.

[0053] In Fig. 3, and thus in the transport state of the second base module 16, the aforementioned sliding door segments are arranged behind a fixed door segment 60 and secured against displacement by means of a transport lock 66 in the form of a Z-shaped securing bracket 68. The securing bracket 68 is screwed to the second side wall 38 at its first end and has a crosspiece 70 at its second end, which rests against the door segments in such a way that they cannot be moved away from the second side wall 38. The sliding door segments are thus secured in their open position. Instead of the single Z-shaped securing bracket, a Z-shaped securing bracket or a U-shaped securing bracket can also be used on each side of the door segments.

[0054] The shaft door 42, and thus also the door sill 64, usually must be aligned or adjusted after the base module 16 has been placed on the base module 14. The final door sill bracket 46 offers various options for this, not all of which necessarily have to be implemented. What all options have in common is that the wall brackets do not have to be removed from the side walls for alignment or adjustment, and thus the final door sill bracket does not have to be loosened or removed. It is sufficient to loosen connections, for example, screw connections between the wall brackets and the side walls, the wall bracket and the door sill support, or the door sill support and the door sill, and then tighten them again after alignment or adjustment.

[0055] A first possibility for aligning or adjusting the shaft door 42 and thus the door sill 64 is to change the position of the wall brackets 56, 59 on the side walls 38, 40. As an example, according to Fig. 4, the vertical leg 57 of the first wall bracket 56, which rests against and is screwed to the second side wall 38, has an elongated hole 63. In the example shown in Fig. 4, the elongated hole 63 is vertically aligned. It is also possible to provide a horizontally oriented elongated hole. After loosening a screw 67 protruding through the elongated hole 63 and screwed into the second side wall 38, the position of the first wall bracket 56 relative to the second side wall 38 can be changed within the frame defined by the elongated hole 63. The same applies analogously to the second wall bracket 59.

[0056] Thus, the first wall bracket 56 and the second wall bracket 59 are designed and attached to the second side wall 38 and the third side wall 40, respectively, such that their position on the second side wall 38 and the third side wall 40, respectively, can be changed together with the door sill support 62. By changing the position of the first wall bracket 56 and / or the second wall bracket 59, the door sill 64 can be aligned or adjusted.

[0057] A second possibility for aligning or adjusting the shaft door 42 and thus the door sill 64 is that the first wall bracket 56, the second wall bracket 59 and the door sill support 62 are designed and connected to one another in such a way that the position of the door sill support 62 can be changed relative to the first wall bracket 56 fastened to the second side wall 38 and relative to the second wall bracket 59 fastened to the third side wall 40. As an example, according to Fig. 5, the door sill support 62 has a first T-slot 69 which is open downwards in the direction of the horizontally extending leg 61 of the first wall bracket 56 and runs transversely to the main extension direction 65 of the door sill support 62. In the first T-slot 69, a head of a screw 71 is arranged, the position of which in the first T-slot 69 can be changed in the direction of extension of the first T-slot 69 and thus transversely to the main extension direction 65 of the door sill support 62.The first wall bracket 56 has a through-hole 73 in its horizontally extending leg 61, which is aligned with the first T-slot 69 of the door sill support 62. The above-mentioned screw 71 extends through the through-hole 73 and, together with the nut 72 screwed onto the screw 71, clamps the door sill support 62 against the first wall bracket 56. The same applies to the connection of the door sill support 62 to the second wall bracket 59. The door sill 64 is arranged on the door sill support 62.

[0058] It is also possible that the first T-slot runs in the main extension direction of the door sill support.

[0059] The through-hole 73 of the first wall bracket 56 has a diameter that is larger than the diameter of the screw 71 protruding through the through-hole 73. This allows the position of the door sill support 62 relative to the wall bracket 56 to be changed transversely to the direction of the first T-slot 69, and thus in the main extension direction 65 of the door sill support 62. Furthermore, the first T-slot 69 is wide enough that the head of the screw 71 arranged in the first T-slot 69 can also be moved transversely to the direction of the first T-slot 69 relative to the door sill support 62. The same applies to the connection of the door sill support to the second wall bracket.

[0060] A third possibility for aligning or adjusting the shaft door 42 and thus the door sill 64 is that the door sill support 62 and the door sill 64 are designed and connected to one another in such a way that the position of the door sill 64 relative to the door sill support 62 can be changed. As an example, according to Fig. 6, the door sill 64 has a second T-slot 75, which is open in the direction of the door sill support 62 and runs in the main extension direction 65 of the door sill support 62. The main extension direction 65 of the door sill support 62 runs perpendicular to the plane of the illustration in Fig. 6. In the second T-slot 75, a head of a screw 77 is arranged, the position of which in the second T-slot 75 can be changed in the direction of extension of the second T-slot 75 and thus in the main extension direction 65 of the door sill support 62 and the door sill 64.The door sill support 62 has a through-hole 79 aligned with the second T-slot 75 of the door sill 64. This allows the screw 77 to extend through the through-hole 79 and, together with the nut 78 screwed onto the screw 77, clamp the door sill 64 against the door sill holder 62.

[0061] It is also possible that the second T-slot runs transversely to the main extension direction of the door sill support.

[0062] The through-hole 79 of the door sill support 62 has a diameter that is larger than the diameter of the screw 77 protruding through the through-hole 79. This allows the position of the door sill 64 relative to the door sill support 62 to be changed transversely to the direction of the second T-slot 75. Furthermore, the second T-slot 75 is wide enough that the head of the screw 77 arranged in the second T-slot 75 can also be moved transversely to the direction of the second T-slot 75 relative to the door sill 64.

[0063] The fixing of the door sill 64 on the door sill support 62 is achieved with several connections distributed over the width of the shaft door 42 as shown in Fig. 6.

[0064] In addition, the landing door 42 can be adjusted or set by changing its position relative to the metal tongues 48 of the upper door support module 44 and the brackets 73, 80 of the final door support 74.

[0065] 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.
