Description

Technical Field

[0001] The invention relates to a shaft module according to the preamble of claim 1 for forming an elevator shaft of an elevator installation, consisting of shaft modules arranged one above the other. Background Art

[0002] For example, during the construction of a building, the creation of an elevator shaft of an elevator system and the subsequent installation of the elevator system are complex and, in this connection, expensive. Usually, the elevator shaft is first constructed and then the elevator system and its components, such as the car, counterweight, drive and guide rails, are installed in the elevator shaft. It has been proposed to manufacture the elevator shaft from a plurality of prefabricated modules, in which the necessary components, such as the shaft door, are already preassembled. In this case, the prefabrication and preassembly are carried out in particular in a factory. In this solution, less time is required at the construction site. In addition, this solution has a positive effect on the quality of the installation and the work safety of the installers.

[0003] The applicant's unpublished international patent application PCT / EP2022 / 061744 describes a shaft module and a method for placing a shaft module on a shaft module located below it to form an elevator shaft of an elevator system. In the transport state of the shaft module, the threshold of the shaft door is fixed to the shaft module by means of a temporary door holder. After the shaft module has been placed on the shaft module located below it, the shaft module is moved from its transport state to an operating state. In this case, the temporary door holder is replaced by the final door holder fixed to the shaft module located below it. Summary of the invention

[0004] The object of the present invention is in particular to provide a shaft module for forming an elevator shaft of an elevator system, which consists of shaft modules arranged one above the other, and which enables the most comprehensive preparation of the shaft module and thus enables simple installation of the elevator system. According to the invention, this object is achieved by a shaft module having the features of claim 1.

[0005] The shaft module according to the invention for forming an elevator shaft of an elevator system, which is composed of shaft modules stacked one above the other, has a first side wall with a door opening, a second side wall adjoining the first side wall at an angle not equal to 180°, and a shaft door with a threshold arranged in the door opening. According to the invention, the threshold of the shaft door is fixed to the second side wall by means of a final threshold holder. The threshold is fixed to the second side wall by the final threshold holder, so that the threshold can remain on the shaft module after the shaft module is mounted on the shaft module located below it and therefore does not need to be updated or changed. Therefore, when the shaft module is manufactured, that is, in particular in the factory, the threshold can already be finally fixed in the shaft module without subsequent work.

[0006] Fastening the threshold together with the final threshold holder to the second side wall is particularly advantageous in shaft modules in which the door opening opens downward in the first side wall, i.e. the first side wall has no horizontally extending region below the door opening. In this case, the threshold of the shaft door cannot be fastened to the first side wall as is customary.

[0007] The shaft module according to the invention is particularly designed to be placed on a shaft module located below it when forming or constructing an elevator shaft. The position and direction specifications used here, such as "lower", "upper", "vertical" or "horizontal", always refer to the orientation of the shaft module in its operating state, that is, when the shaft module forms a part of the elevator shaft after its assembly.

[0008] The shaft module can, at least with respect to the side walls, for example, consist essentially of concrete, in particular reinforced concrete, wood or metal, in particular metal profiles. When consisting of concrete, the shaft module can have a so-called lost form, ie a form that is not removed after the concrete has hardened.

[0009] The shaft module can be designed as a so-called top module or as a so-called bottom module. With the top module, the elevator shaft is closed upwards. The shaft module comprises a top module ceiling, which as a shaft ceiling closes the shaft upwards. A drive machine for moving the car during operation of the elevator system can be arranged in the top module. A plurality of bottom modules are arranged below the top module, which together with the top module form the elevator shaft. The shaft modules are designed so that they can be placed, for example, by means of a crane onto the shaft module located below them.

[0010] 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.

[0011] The second side wall adjoins the first side wall in particular at an angle of 90°. In particular, the shaft module and thus also the elevator shaft comprising the shaft module have a rectangular cross section. However, different cross sections are also possible. The cross section can also be circular or oval, for example, whereby the transition from the first side wall to the second side wall can be defined freely to a large extent.

[0012] The threshold extends horizontally, closes the shaft door downwards and therefore extends at least almost over the entire width of the door opening of the first side wall. The threshold is designed in particular as a flat rail extending longitudinally in a main extension direction, in particular made of metal. In the operating state of the elevator installation, the threshold in particular covers a gap extending in the main extension direction between the elevator shaft and the floor of a floor of a building containing the elevator shaft and adjacent to the elevator shaft.

[0013] Here, the fixing of the threshold by means of the final threshold holder is to be understood as meaning that after installation on the shaft module located below, the fixing of the threshold before the placement of the shaft module does not have to be or is not released or removed. However, it is entirely possible that after installation on the shaft module located below, the position of the final threshold holder and thus also the position of the threshold changes slightly. The threshold can thus be aligned or adjusted.

[0014] The fixing of the door sill can also be strengthened after being installed on the shaft module below it.For example, the door sill can be fixed on the shaft module below it by other retaining parts without loosening or removing the existing final door sill retaining parts.

[0015] The final door sill holder is characterized in that it has a load-bearing function when fastening the door sill to the second side wall and thus to the shaft module in the transport state of the shaft module and in the operating state of the shaft module, ie during operation of the elevator installation.

[0016] The operation of an elevator system is to be understood here as meaning that the car of the elevator system moves in the elevator shaft and, in particular, that persons and / or goods are transported in the car.

[0017] The shaft module is placed in a transport state, in particular in a factory. Side walls and, if necessary, a shaft module cover are built and a shaft door is arranged in the door opening, whereby the shaft opening is closed. In addition, other elevator components, such as guide rails or a drive motor for an elevator device, can be arranged on the shaft module. Subsequently, the shaft module is transported to a construction site where the elevator device and thus the elevator shaft should be built. The shaft module is placed on the shaft module located below it while still in the transport state of the shaft module. In the further installation process, these shaft modules then enter their operating state from the transport state. Here, it is feasible to place the shaft module directly in the operating state after placement, or to first stack all the shaft modules forming the elevator shaft one above the other, and then place each shaft module in its operating state.

[0018] In one embodiment of the invention, a third side wall opposite to the second side wall is connected to the first side wall. The threshold of the shaft door is also fixed to the third side wall by means of the last threshold holder. This makes it possible to fix the threshold particularly simply and cost-effectively.

[0019] The door sill holder thus extends between the second and third side walls. The third side wall is in particular also connected to the first side wall at an angle of 90°, so that the third side wall extends parallel to the second side wall.

[0020] It is also possible that the first side wall has more than one door opening, in which a shaft door is arranged in each case. In this case, a plurality of elevator cars can be moved side by side in the shaft formed by the shaft module. In this case, the door sill carrier can also extend between the second and third side walls and a plurality of door sills arranged adjacent to one another are fastened to the second and third side walls. However, it is also possible to arrange a plurality of intermediate retaining elements between the door openings of the first side wall, for example projections extending inwards in the vertical direction into the elevator shaft, or a plurality of horizontally extending carriers (for example in the form of so-called separating beams or segment beams), and the individual door sills are fastened to the second side wall and to the intermediate retaining element, to the third side wall and to the intermediate retaining element, or to both intermediate retaining elements by means of a plurality of door sill retaining elements.

[0021] In one embodiment of the invention, the final door sill holder has a first corner piece fixed to the second side wall, a second corner piece fixed to the third side wall, and a door sill carrier supported on the first corner piece and the second corner piece. This makes it possible to fix the door sill simply and stably. The use of the door sill carrier advantageously enables the use of a standard door sill, which can also be used in conventionally manufactured elevator shafts, i.e., not composed of prefabricated shaft modules. Such standard door sills are available on the market with great selectivity and at a favorable price.

[0022] The two corner pieces are especially designed mainly in an L-shape, have vertically extending and horizontally extending legs, and are especially screwed to the second or third side wall. They are especially identically or similarly constructed and are especially made of metal.

[0023] The sill carrier is in particular placed on the two corner pieces and is therefore supported from above on the corner pieces. The sill carrier is in particular connected to the corner pieces, in particular screwed. The sill is in particular placed on the sill carrier and is therefore supported from above on the sill carrier. The sill is in particular connected to the sill carrier, for example screwed.

[0024] In the design of the present invention, the first corner piece and the second corner piece are designed and fixed on the second side wall or the third side wall in such a way that their positions on the second side wall or the third side wall can be changed together with the threshold carrier. The first corner piece has a first adjustment structure for this purpose, and the second corner piece has a second adjustment structure. This advantageously allows the threshold holder to be adjusted or adjusted after the shaft module is mounted on the shaft module located below, and thus the threshold, without having to loosen or remove the threshold holder.

[0025] The corner piece has in particular a slot as an adjustment structure, through which a screw or bolt for fixing to the second or third side wall passes. Therefore, after loosening the screw or tightening the nut on the bolt, the slot enables the position of the corner piece to be changed relative to the screw or bolt, and thus the position of the corner piece relative to the second or third side wall to be changed.

[0026] In particular, it is possible to change the position of the corner piece on the second or third side wall in the vertical direction. The elongated hole in the corner piece extends in particular vertically.

[0027] In the design of the present invention, the first corner piece, the second corner piece and the threshold carrier are designed so that the position of the threshold carrier relative to the first corner piece fixed to the second side wall and relative to the second corner piece fixed to the third side wall can be changed. To this end, the first corner piece, the second corner piece and / or the threshold carrier have a suitable adjustment structure. This advantageously allows the threshold holder and thus the threshold to be further adjusted or regulated after the shaft module is mounted on the shaft module located therebelow without having to loosen or remove the threshold holder.

[0028] The change in the position of the sill carrier relative to the corner piece fixed to the side wall can be carried out in particular along a main extension direction of the sill carrier or transversely to the main extension direction of the sill carrier. The main extension direction of the sill carrier extends between the first and second corner pieces, that is to say parallel to the first side wall between the second and third side wall.

[0029] For this purpose, the threshold carrier has, for example, a so-called first T-slot as an adjustment structure, which is open downward in the direction of the horizontally extending leg of the first corner piece and extends transversely to the main extension direction of the threshold carrier or in the main extension direction. The head of a screw or a so-called sliding nut can be arranged in the first T-slot, and its position in the first T-slot can be changed in the extension direction of the first T-slot. In this case, the first corner piece has in particular one or more through holes in its horizontally extending leg, which are aligned toward the first T-slot of the threshold carrier. Therefore, the above-mentioned screw or the screw that can be screwed into the sliding nut can extend through the through hole and, if necessary, clamp the threshold carrier toward the first corner piece together with the nut. The same applies to the connection of the threshold carrier to the second corner piece.

[0030] Additionally or alternatively, the through hole of the first corner piece as the adjusting device of the first corner piece may have a diameter that is larger than the diameter of the screw extending through the through hole. Therefore, the position of the threshold carrier can also be changed transversely to the extension direction of the first T-slot. As an alternative or supplementary solution, the head of the screw arranged in the first T-slot or the sliding nut can also be moved relative to the threshold carrier transversely to the extension direction of the first T-slot. The same applies to the connection between the threshold carrier and the second corner piece. However, other technical implementation solutions are also feasible.

[0031] In the embodiment of the invention, the sill carrier and the sill are connected to one another and are configured such that the position of the sill relative to the sill carrier can be changed. To this end, the sill holder and / or the sill have a suitable adjustment structure. This advantageously allows the sill holder and thus the sill to be further adjusted or adjusted after the shaft module has been mounted on the shaft module located therebelow, without having to loosen or remove the sill holder.

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

[0033] For this purpose, the threshold has, for example, a second T-slot as an adjustment structure, which is open in the direction of the threshold carrier and extends in the main extension direction of the threshold carrier or transversely to the main extension direction of the threshold carrier. The head of a screw or a so-called sliding nut can be arranged in the second T-slot, whose position in the second T-slot can be changed in the extension direction of the second T-slot. In this case, in particular, the threshold carrier has a through hole or a plurality of through holes aligned with the second T-slot of the threshold. Thus, the above-mentioned screw or the screw that can be screwed into the sliding nut can extend through the through hole and, if appropriate, clamp the threshold against the threshold holder together with the nut. However, other technical implementations are also possible.

[0034] Additionally or alternatively, the through hole of the threshold carrier as an adjustment structure of the threshold carrier can, for example, have a diameter greater than the screw protruding through the through hole. As a result, the position of the threshold relative to the threshold carrier can also be changed transversely to the extension direction of the second T-slot. Alternatively or additionally, the head of the screw or the sliding nut arranged in the second T-slot can also be moved relative to the threshold transversely to the extension direction of the second T-slot. However, other technical implementation solutions are also feasible.

[0035] In one embodiment of the invention, the shaft door of the shaft module is fastened to the shaft module by means of an upper door holding module. The shaft door is thus fastened to the shaft module via the threshold and the final threshold holder and additionally by means of the upper door holding module. This enables a particularly stable fastening of the shaft door in the shaft module.

[0036] The upper door holding module can in particular change the position of the shaft door in the vertical direction within certain limits. For this purpose, the upper door holding module has, for example, slotted holes which provide the possibility of adjustment in the vertical direction.

[0037] In the embodiment of the invention, for closing and opening the shaft door, the shaft door has a movable (translationally displaceable) door section which is secured against movement in the transport state of the shaft module by means of a transport securing device. Damage to the door section due to uncontrolled movements is thereby avoided. The door section is secured in particular in its open position. Advantageously, the shaft module is thus accessible in its transport state, which helps during transport and placement on the shaft module located below it. Furthermore, the door section is thereby protected against twisting or deformation during transport of the shaft module.

[0038] The shaft module is in the transport state, for example, before it is placed on the shaft module located below it.

[0039] The transport fastening device in particular has a fastening clamp, which is fixed on the second side wall and fastens the door section in its open position. The transport fastening device can be realized particularly simply and cost-effectively. The transport fastening device can be made of, for example, one or two Z-shaped corner pieces or U-shaped clamps made of wood or metal, which are screwed on the second side wall and surround the door section in the following manner so that it keeps the door section in its open position. In this case, the shaft door can have a plurality of door sections, which move in the same direction to open the shaft door. In this case, the door section is fastened relative to the second side wall. The shaft door can also have a plurality of door sections, which move in opposite directions in order to open the shaft door. In this case, the door section is fastened relative to the second side wall, and another door section is fastened relative to the third side wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] according to Figure 1 , the elevator installation 10 has an elevator shaft 12 for a three-story building, which in the present embodiment consists of a first bottom module 14, a second bottom module 16 and a top module 18. Depending on the number of floors, the elevator shaft 12 may also include a second bottom module 16. The shaft modules 14, 16, 18 are pre-produced in a factory and provided with elevator components. The shaft modules are then brought to the construction site and stacked one on top of the other. The shaft modules 14, 16, 18 all have a predominantly square basic shape. The shaft modules are in particular predominantly made of wood. Of course, other materials, such as concrete, are also conceivable.

[0049] exist Figure 21 shows how a top module 18 is placed from above onto a second bottom module 16 by means of a crane 20. The second bottom module 16 has already been placed in the same way onto the first bottom module 14. The bottom module 14 rests on a foundation (not shown in further detail) of the elevator shaft 12. The bottom modules 14, 16 form an upwardly open, not yet completed elevator shaft which is closed upwardly by placing the top module 18.

[0050] In addition, according to Figure 1 The elevator installation 10 of FIG. 1 has a car 22 which can be moved vertically in an elevator shaft 12 along guide rails (not shown). For this purpose, the elevator installation 10 has a sling 24, a first end 26 of which is fixed in the top module 18. The sling then extends around the car 22 at the bottom and is guided by a drive 28 arranged in the top module 18 opposite the first end 26 of the sling 24. From there, the sling extends through the suspension of the counterweight 30 to its second end 32, which is fixed in the area of ​​the drive 28. The drive 28 can move the sling 24 and thus also the car 22 in the elevator shaft 12.

[0051] like Figure 3 As shown, the second floor module 16, i.e. the shaft module for forming the elevator shaft 12 of the elevator installation 10, has a first side wall 34 with a door opening 36 that opens downward. Therefore, the first side wall 34 mainly has an inverted "U" shape. Figure 3 In the view of FIG. 1 , the second side wall 38 is connected to the first side wall 34 on the left side at an angle of 90°, ie, not equal to 180°, and the third side wall 40 is connected to the first side wall 34 on the right side.

[0052] The shaft door 42 is arranged in the door opening 36. The first floor module 14 and the top module 18 can be designed identically to the second floor module 16, which will be described in detail below, at least with regard to the shaft door. The shaft door 42 is primarily fixed by means of an upper door holding module 44. The upper door holding module 44 has three metal tongues 48, by means of which the horizontally extending upper part of the door frame 50, the so-called door arch 52, is screwed to the crossbeam 54 of the first side wall 34. Since the metal tongues 48 are in the Figure 3 The door arch 52 and the cross beam 54 are arranged behind the door arch and the cross beam, so the door arch and the cross beam are represented by dotted lines.

[0053] The shaft door 42 has a horizontally extending threshold 64 which closes the shaft door 42 at the bottom. The threshold extends over almost the entire width of the door opening 36 of the first side wall 34 and is designed as a flat rail extending longitudinally in a main extension direction 65 of the threshold 64, which is especially made of metal.

[0054] The threshold 64 is fixed or fastened to the second side wall 38 and the third side wall 40 and thus to the shaft module 16 by means of the final threshold holder 46. The threshold holder 46 has a first corner piece 56 having two legs arranged perpendicular to each other. The vertically extending legs ( Figure 4 and Figure 5 57) is screwed onto the second side wall 38.

[0055] The second corner piece 59, which is designed identically to the first corner piece 56, is screwed onto the third side wall 40 at the same height as the first corner piece 56. A sill carrier 62 of the final sill holder 46 extends between the second side wall 38 and the third side wall 40, which sill carrier is in particular mainly composed of a metal profile. The sill carrier 62 thus also extends in the main extension direction 65 of the sill 64. The sill carrier 62 rests at its two ends on horizontally extending legs ( Figure 4 and Figure 5 61 in the middle) and is therefore supported on the two corner pieces 56, 59. The threshold 64 is located on the threshold carrier 62, which is mainly used for the shaft door 42 during the operation of the elevator system 10. Figure 3 The vehicle is guided by an invisible, movable door section.

[0056] The movable door section Figure 3 In the transport state of the second floor module 16, the second floor module 16 is arranged behind the fixed door section 60 and is secured against movement by means of a transport securing device 66 in the form of a Z-shaped securing clip 68. The securing clip 68 is screwed to the second side wall 38 at its first end and has a cross piece 70 at its second end, which rests on the door section in such a way that it cannot be moved away from the second side wall 38. The movable door section is thus secured in its open position. Instead of a Z-shaped securing clip, a Z-shaped securing clip or also a U-shaped securing clip can also be used on each side of the door section.

[0057] The shaft door 42 and thus also the threshold 64 usually have to be aligned or adjusted after the bottom module 16 is mounted on the bottom module 14. For this purpose, the final threshold holder 46 offers different possibilities that do not necessarily all have to be realized. All possibilities have in common that the corner piece does not need to be removed from the side wall for the alignment or adjustment, and therefore the final threshold holder does not need to be loosened or removed. It is sufficient to loosen the connection, for example a screw-on, between the corner piece and the side wall, between the corner piece and the threshold carrier or between the threshold carrier and the threshold, and tighten it again after the alignment or adjustment.

[0058] A first possibility for aligning or adjusting the shaft door 42 and thus also the door sill 64 is to change the position of the corner pieces 56, 59 on the side walls 38, 40. As an example, Figure 4 As shown, the vertical leg 57 of the first corner piece 56, which is in contact with the second side wall 38 and is screwed, has an elongated hole 63. Figure 4 In the example shown, the slot 63 is oriented vertically. A horizontally oriented slot can also be provided. After loosening the screw 67 extending through the slot 63 and screwed into the second side wall 38, the position of the first corner piece 56 relative to the second side wall 38 in the frame defined by the slot 63 can be changed. This applies similarly to the second corner piece 59.

[0059] Therefore, the first corner piece 56 and the second corner piece 59 are implemented and fixed on the second side wall 38 or the third side wall 40 in such a manner that the positions of the first corner piece 56 and the second corner piece 59 on the second side wall 38 or the third side wall 40 can be changed together with the door sill carrier 62. By changing the positions of the first corner piece 56 and / or the second corner piece 59, the door sill 64 can be aligned or adjusted.

[0060] A second possibility for aligning or adjusting the shaft door 42 and thus also the threshold 64 is that the first corner piece 56, the second corner piece 59 and the threshold carrier 62 are designed and connected to one another in such a way that the position of the threshold carrier 62 relative to the first corner piece 56 fixed to the second side wall 38 and relative to the second corner piece 59 fixed to the third side wall 40 can be changed. For example, Figure 5 As shown, the sill carrier 62 has a first T-slot 69 which opens downward in the direction of the horizontally extending leg 61 of the first corner piece 56 and extends transversely to the main extension direction 65 of the sill carrier 62. The head of a screw 71 is arranged in the first T-slot 69, and the position of the screw 71 in the first T-slot 69 can be changed along the extension direction of the first T-slot 69 and thus transversely to the main extension direction 65 of the sill carrier 62. The first corner piece 56 has a through hole 73 in its horizontally extending leg 61, which is aligned with the first T-slot 69 of the sill carrier 62. The above-mentioned screw 71 protrudes through the through hole 73 and, together with the nut 72 screwed on the screw 71, clamps the sill carrier 62 toward the first corner piece 56. The same applies to the connection of the sill carrier 62 to the second corner piece 59. The sill 64 is arranged on the sill carrier 62.

[0061] It is also possible that the first T-slot extends along a main extension direction of the sill carrier.

[0062] The diameter of the through hole 73 of the first corner piece 56 is larger than the diameter of the screw 71 passing through the through hole 73. Therefore, the position of the sill carrier 62 relative to the corner piece 56 can also be changed transversely to the extension direction of the first T-slot 69 and thus in the main extension direction 65 of the sill carrier 62. In addition, the width of the first T-slot 69 enables the head of the screw 71 arranged in the first T-slot 69 to be moved relative to the sill carrier 62 transversely to the extension direction of the first T-slot 69. The same applies to the connection of the sill carrier to the second corner piece.

[0063] A third possibility for aligning or adjusting the shaft door 42 and thus also the threshold 64 is to construct and connect the threshold carrier 62 and the threshold 64 together in such a way that the position of the threshold 64 relative to the threshold carrier 62 can be changed. Figure 6 As shown, the sill 64 has a second T-shaped groove 75 which is open in the direction toward the sill carrier 62 and extends in the main extension direction 65 of the sill carrier 62. Figure 6 The head of the screw 77 is arranged in the second T-slot 75, and the position of the screw in the second T-slot 75 can be changed in the extension direction of the second T-slot 75 and thus in the main extension direction 65 of the sill carrier 62 and the sill 64. The sill carrier 62 has a through hole 79, which is aligned with the second T-slot 75 of the sill 64. Therefore, the screw 77 can protrude through the through hole 79 and, together with the nut 78 screwed on the screw 77, clamp the sill 64 toward the sill carrier 62.

[0064] It is also possible that the second T-slot extends transversely to the main extension direction of the sill carrier.

[0065] The diameter of the through hole 79 of the door sill carrier 62 is larger than the diameter of the screw 77 extending through the through hole 79. Therefore, the position of the door sill 64 relative to the door sill carrier 62 can also be changed transversely to the extending direction of the second T-shaped slot 75. In addition, the width of the second T-shaped slot 75 enables the head of the screw 77 disposed in the second T-shaped slot 75 to also move relative to the door sill 64 transversely to the extending direction of the second T-shaped slot 75.

[0066] The door sill 64 is fixed to the door sill carrier 62 by Figure 6 This is achieved by a plurality of connecting pieces distributed over the width of the shaft door 42.

[0067] Furthermore, the position of the shaft door 42 can be adjusted by changing its position relative to the metal tongue 48 of the upper door holding module 44 and relative to the brackets 73 , 80 of the final door holder 74 .

[0068] Finally, it should be pointed out 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 pointed out 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 above-described embodiments. Reference signs in the claims should not be considered as limiting.
