Definitions

  • the invention relates to an elevator shaft for an elevator system in a building according to the preamble of claim 1.
  • an elevator shaft of an elevator system for example when constructing a building, and the subsequent installation of the elevator system is complex and therefore associated with not inconsiderable costs.
  • the elevator shaft is built first and then the elevator system with its components such as cabin, counterweight, drive machine and guide rails are installed in the elevator shaft.
  • the prefabrication and preassembly takes place in particular in a factory. This approach requires less time on site. In addition, it has positive effects on the quality of the installation and the occupational safety of the installation personnel.
  • the U.S. 3,991,528 describes an elevator shaft for an elevator system in a building.
  • the building comprises several floors, with one floor being separated from the floor below by a floor.
  • the elevator shaft is formed by a plurality of shaft modules placed one on top of the other, each of which has an upper edge, a lower edge and a first side wall with a door opening.
  • a lower edge of a first shaft module and an upper edge of a second shaft module arranged below the first shaft module form a joint between the first shaft module and the second shaft module.
  • a storey floor adjoining the first side wall of the first shaft module ends flush with the lower edge of the first shaft module.
  • the elevator shaft according to the invention is formed by a plurality of shaft modules placed one on top of the other, each of which has an upper edge, a lower edge and a first side wall with a door opening.
  • a lower edge on an outside of a first shaft module and an upper edge on an outside of a second shaft module arranged below the first shaft module form an outer joint between the first shaft module and the second shaft module.
  • the building comprises several floors, with one floor being separated from the floor below by a floor.
  • a floor adjoining the first side wall of the first shaft module on the outside covers the said outer joint between the first side wall of the first shaft module and the first side wall of the second shaft module.
  • Said outer joint is thus covered by the storey floor on an outside of the elevator shaft.
  • the outer joint is thus at a height of the elevator shaft that lies within the vertical extension of the floor.
  • Said external joint can also be referred to in simplified terms as an external joint between the first and second shaft module.
  • a joint between two adjacent shaft modules is not very attractive to the eye.
  • dust and the like can collect in such a joint over time, which further worsens the visual impression.
  • a joint that is visible to users of the elevator system would therefore have to be covered, for example plastered, so that a smooth surface is produced.
  • the floor covers the outer joint between the first and the second shaft module, the joint is no longer visible from the building. It is therefore not necessary to cover the outer joint in one work step after the first shaft module has been placed on the second shaft module. Such a work step is therefore not necessary, which saves time and money.
  • An elevator system is used to transport people and goods between storeys or floors of a building that are arranged one above the other.
  • a first floor is delimited from an underlying, second floor with a floor.
  • the floor is to be understood here as the entire floor, i.e. including a floor covering or finished floor that closes the floor upwards in the direction of the first floor, and a ceiling finish, which closes the floor downwards in the direction of the second floor.
  • the elevator system has a cabin which is vertically displaced in the elevator shaft of the elevator system.
  • the elevator shaft has at least one door opening per floor through which the car can be entered and exited.
  • the mainly vertical elevator shaft is here composed of individual shaft modules, one shaft module being provided for each floor. Elevator components can be installed in the shaft modules prior to assembling the elevator shaft. This aspect does not play a role here, so that it will not be discussed further.
  • the shaft modules have a cuboid basic shape with a total of four side walls.
  • the shaft modules can also have a different basic shape, for example with a circular or oval cross section, sections of the side wall then forming individual side walls.
  • the shaft modules of the elevator shaft can be designed as a so-called top module or as so-called base modules.
  • a lift shaft is closed at the top with a top module. It contains a top module cover, which as a shaft cover closes the elevator shaft at the top.
  • Several basic modules are arranged below a top module, which together with the top module form the elevator shaft. The basic modules do not all have to be exactly the same; this applies in particular to the lowest basic module.
  • the shaft modules are designed in such a way that they can be placed on a shaft module below using a crane, for example.
  • the shaft modules have an upper edge and a lower edge, with top, bottom, vertical, horizontal and information about a height relating to the alignment of the shaft module in the elevator shaft.
  • the lower and/or lower edge does not have to be level or flat over the thickness of the side walls, but can have a contour so that the upper or lower edge on the outside of a side wall is at a different height than the upper or .lower edge on the inside of a side panel.
  • a lower edge on an outside of a first shaft module and an upper edge on an outside of a second shaft module arranged below the first shaft module form an outer joint, i.e. a joint directed outwards from the elevator shaft, between the first shaft module and the second shaft module.
  • An internal impact is also formed, i.e. an impact directed inwards into the elevator shaft, but this is of no further interest here and will not be described further.
  • the outer joint is understood here to mean the contact area between the first shaft module and the second shaft module. This can result in a small gap or a small horizontal offset. Even without a gap or offset, the outer joint is visible or optically perceptible.
  • the shaft modules of the elevator shaft can also have more than one side wall with a door opening.
  • the covering of the outer joint between the first and the second shaft module according to the invention is particularly advantageous if at least the first side wall of the shaft module is made of fair-faced concrete. Concrete surfaces made of fair-faced concrete remain visible and are not plastered or faced. As a result of the said covering, the outer joint does not have to be plastered or faced either, which leads to a particularly low effort for the completion of the outside of the shaft modules and thus of the entire elevator shaft.
  • shaft module in particular all side walls of the shaft modules, are made of fair-faced concrete.
  • shaft modules are mainly made of a different material, for example a concrete other than exposed concrete or made of wood.
  • the first side wall of a shaft module has a substructure with a substructure height that extends between the door opening and the lower edge of the shaft module.
  • the substructure height of the substructure of the first side wall is smaller than a storey floor height of the storey floor adjoining the substructure.
  • Said substructure extends in the horizontal direction over the entire width of the first side wall of the shaft module.
  • a shaft door is arranged in the door opening of the first side wall of each shaft module.
  • the shaft doors are already arranged in the door openings before the shaft modules are placed on top of one another. This allows the landing doors to be arranged in the factory. In this case, the shaft doors also close the elevator shaft as it is being constructed and prevent people or objects from falling into the elevator shaft.
  • a shaft door arranged in the door opening of a first side wall of a shaft module is fixed to the first side wall of this shaft module by means of a lower door bracket on the substructure of the first side wall, and the lower door bracket is arranged completely within this shaft module.
  • the lower door holder thus does not protrude downwards over the lower edge of the shaft module. This advantageously protects the bottom door bracket from damage during transport of the well module from the factory to the building in which it is installed.
  • the shaft module can thus be placed directly on its lower edge on a flat surface or another shaft module, without it being necessary to underlay it with individual spacers, for example in the form of blocks of wood.
  • the lower door holder has, for example, one or more brackets which are screwed to the first side wall of the shaft module on the substructure of the first side wall. It is also possible that the brackets are additionally fixed in an area above the substructure on the first side wall or on another side wall.
  • the landing door in particular a frame and a door sill of the landing door, are supported on the angles mentioned and are particularly screwed to them.
  • the first side wall of a shaft module has a superstructure that extends between the door opening and the upper edge of the shaft module. Said superstructure extends in the horizontal direction over the entire width of the first side wall of the shaft module.
  • a landing door arranged in the door opening of a first side wall of a shaft module is fixed to the first side wall of this shaft module by means of an upper door bracket on the superstructure of the first side wall, and the upper door bracket is arranged completely inside this shaft module.
  • the upper door bracket thus does not protrude upwards over the upper edge of the shaft module. This advantageously protects the upper door bracket from damage during transport of the shaft module from the factory to the building in which it is installed.
  • a further shaft module or other parts can be placed on the upper edge of the shaft module before the elevator shaft is built, for example in the factory in which the shaft modules are manufactured.
  • the upper door bracket has, for example, one or more brackets or brackets, which are screwed to the superstructure of the first side wall of the shaft module. It is also possible for the brackets or brackets to be additionally fixed in an area below the superstructure on the first side wall or on another side wall.
  • the brackets or lugs mentioned are also screwed to the shaft door, in particular to an upper, horizontally extending part of a door frame, which is also referred to as a door jamb, and fix the parts mentioned to the first side wall of the shaft module.
  • the elevator shaft according to the invention is in particular integrated into a building.
  • an elevator system 10 for a three-story building has an elevator shaft 12, which in the present exemplary embodiment is composed of a first basic module 14, a second basic module 16 and a top module 18, each of which is also referred to as a shaft module.
  • the elevator shaft 12 can include further second basic modules 16 .
  • Said shaft modules 14, 16, 18 are pre-produced in a factory and provided with elevator components. They are then brought to the construction site and placed one on top of the other.
  • the shaft modules 14, 16, 18 all have a mainly cuboid basic shape and therefore each have four side walls. In particular, they are mainly made up of exposed concrete. Of course, other materials such as wood are also conceivable.
  • FIG. 2 shows how the second basic module 16 is placed onto the first basic module 14 from above by means of a crane 20 .
  • the second basic module 16 can be referred to as a first shaft module and the first basic module 14 as a second shaft module.
  • the first basic module 14 was previously placed in a similar manner on a foundation of the elevator shaft 12 that is not shown in any more detail.
  • the first basic module 14 is integrated into a building 21 under construction, from which in the 2 a lowest, first floor 23 has been completed in the shell.
  • a second floor 25 which is under construction and is arranged above the first floor 23 is delimited by a floor 27 from the first floor 23 at the bottom.
  • the first basic module 14 is assigned to the first floor 23 and the second basic module 16 to the second floor 25 .
  • the elevator system 10 also has a cabin 22 along not shown guide rails in the elevator shaft 12 can be moved vertically.
  • the elevator system 10 has a suspension element 24 whose first end 26 is fixed in the top module 18 . It then runs around the bottom of the cabin 22 and is guided over a drive machine 28 arranged opposite the first end 26 of the suspension element 24 in the top module 18 . From there it runs through a suspension of a counterweight 30 to its second end 32 which is fixed in the area of the engine 28 .
  • the drive machine 28 can move the suspension element 24 and thus the car 22 in the elevator shaft 12 .
  • the second basic module 16 has a first side wall 34 with a door opening 36 .
  • a second side wall 38 adjoins the left side of the first side wall 34 and a third side wall 40 adjoins the right side.
  • a fourth side wall of the second basic module 16 runs parallel to the first side wall and cannot be seen.
  • the second basic module 16 has on its upper side an upper edge 33 running around all four side walls 36, 38, 40 and on its underside an upper edge 33 running around all four side walls 36, 38, 40 peripheral lower edge 35 on.
  • the upper and lower edges 33, 35 are flat or planar across the thickness of the side walls 34, 38, 40.
  • the upper and lower edge can also have a contour, so that the upper or lower edge on an outside of a side wall is at a different height than the upper or lower edge on an inside of a side wall.
  • a shaft door 42 is arranged in the door opening 36 .
  • the shaft door 42 is fixed to the second basic module 16 by means of an upper door holder 44 and a lower door holder 46 .
  • the upper door holder 44 has three metal tongues 48 distributed in the horizontal direction, by means of which an upper, horizontally extending part of a door frame 50, a so-called door jamb 52, is fastened to a superstructure 54 of the first side wall 34.
  • the superstructure 54 extends between the door opening 36 and the upper edge 33 of the first side wall 34 over the entire width of the first side wall 34. Since the door post 52 and the metal tongues 48 in the 3 are arranged behind the superstructure 54, they are shown in dashed lines. Like in the 3 clearly visible, the metal tongues 48 and thus the upper door holder 44 do not protrude beyond the upper edge 33 of the second basic module 16, so that they are arranged completely within the second basic module 16.
  • the lower door bracket 46 has four horizontally distributed brackets 56, in particular made of metal, by means of which a vertically running part 58 of the door frame 50 and a horizontally running door sill 59 are attached to a substructure 61 of the first side wall 34.
  • the door sill 59 runs slightly higher than an upper edge 63 of the substructure 61.
  • the parts mentioned are thus supported on the brackets 56 downwards.
  • the base 61 extends between the door opening 36 and the lower edge 35 of the first side wall 34 over the entire width of the first side wall 34 and has a base height h 1 .
  • the substructure height h 1 corresponds to the distance between the upper edge 63 of the substructure 61 and the lower edge 33 of the first side wall 34.
  • the brackets 56 and thus the lower door holder 46 do not protrude beyond the lower edge 35 of the second basic module 16, so that they are arranged completely within the second basic module 16.
  • the second basic module 16 was placed on the first basic module 14 so that it is arranged above the first basic module 14 . It is arranged in such a way that the individual side walls 34, 38, 40 of the two basic modules 14, 16 are aligned with one another.
  • the lower edge 35 of the second basic module 16 and the upper edge of the first basic module 14 form a horizontal, circumferential joint 60 between the second basic module 16 and the first basic module 14.
  • the upper edge 33 and the lower edge 35 of the basic module 14 , 16 are designed to be planar, the joint 60 forms both an internal joint, ie one directed inwards into the elevator shaft 12, and also an external joint, ie directed outside the elevator shaft 12.
  • the joint 60 thus runs on an inside and on an outside of the second shaft module 16 at the same height with respect to the elevator shaft 12.
  • the floor 27 delimiting the second floor 25 from the first floor 23 is arranged opposite the second basic module 16 and the first basic module 14 in such a way that it covers the joint 60 between the first side wall 34 of the second basic module 16 and the first side wall 34 of the first basic module 14 .
  • the floor 27 borders directly on the first side walls 34 of the two basic modules 14, 16 from the outside and extends over a height range in which the joint 60 runs. The part of the joint 60 running on the first side wall 34 of the basic modules 14 , 16 is therefore not visible from outside the elevator shaft 12 .
  • the storey floor 27 has a storey floor height h 2 which is greater than the substructure height h 1 of the substructure 61 of the first side wall 34 of the second basic module 16, i.e. the substructure height h 1 of the substructure 61 is smaller than the storey floor height h 2 of the storey floor 27.
