Description

Technical Field

[0001] The invention relates to a method for building an elevator into a destination location from a plurality of prefabricated elevator modules. Background Art

[0002] In the past, elevators were built by installing the components one by one into the hoistway. A disadvantage is that all elevator installation work performed on the construction site consumes time and complicates the logistics of the construction site. A further disadvantage is that the exact positioning of the components requires a lot of adjustments on site, which leads to delays in the subsequent steps of the elevator construction and in the construction steps of other parts of the building. Furthermore, modular elevator solutions are known, in which the elevator is built from prefabricated modules. Modular elevator solutions involve building prefabricated elevator modules in a factory, transporting them to the construction site, and stacking them on top of each other to the desired destination location, for example inside a building.

[0003] There is a modular solution in which the prefabricated modules include a pit module, a top module including machinery for driving the lifting ropes, and one or more intermediate modules between the pit module and the top module. Each module may include a module frame, and in the stack, a plurality of prefabricated modules are stacked on top of each other so that the frame of each prefabricated module bears the weight of the frame of the module stacked on top of it. The pit module rests on the floor of the building. A solution of the above type is disclosed in document EP3747820A1. In one of the disclosed solutions, the module frame of the module may be a beam frame. In this modular solution, the modules may have been prefabricated in the factory to a high degree of precision, which makes the stacking process very rapid. In this prior art solution, there is only a small amount of on-site adjustment work after the stacking. However, it has been noted that the construction work can still be improved in one or more of the following aspects: the efficiency of the manufacturing work of the modules at the factory, the simplicity and time consumption of the steps that need to be performed on the construction site to achieve good accuracy of the placement of the components, and the accuracy of the placement of the components of the final elevator. Summary of the invention

[0004] The object of the present invention is to introduce an improved method for building an elevator to a destination location from a plurality of prefabricated elevator modules.

[0005] The object is in particular to introduce a solution by which one or more of the above-mentioned problems of the prior art and / or the disadvantages discussed or hinted at elsewhere in the description can be solved.

[0006] With this method, the manufacture of elevator modules can be performed with high precision, efficiency and ergonomics. With this method, the manufacturing precision of the modules can be improved, so that the work to be performed later on the construction site is simplified and reduced. As a result, only a small amount of time and work is required on the construction site, which reduces the interference with other operations taking place on the construction site and its surroundings.

[0007] A new method for building an elevator to a destination location from a plurality of prefabricated elevator modules is proposed. The method comprises manufacturing a plurality of (prefabricated) elevator modules at a location remote from the destination location, such as at a factory. The manufacturing comprises:

[0008] providing one or more module frames having a longitudinal axis; and

[0009] positioning the one or more module frames in a horizontal orientation wherein the longitudinal axis is horizontal; and

[0010] When the one or more module frames are in a horizontal position, installation work is performed on the one or more module frames.

[0011] After said manufacturing, the method comprises:

[0012] transporting the module to the vicinity of the destination location; and

[0013] The modules are arranged one above the other into a destination location such that they are in a vertically oriented position, wherein in the vertically oriented position the longitudinal axes of the module frames of the modules are vertical.

[0014] With this solution, one or more of the above-mentioned purposes can be achieved. The module frame to be processed in a horizontally oriented position is easily accessible from all directions, in particular from the end direction and from the side direction, so that the installation work can be carried out accurately, efficiently and ergonomically. In particular, this contributes to the accuracy, efficiency and ergonomics of mounting the components on the frame, adjusting the position of the beams of the frame, and accurately aligning the components to be fixed on the frame.

[0015] Preferred further details of the method are presented below, which further details can be combined with the method alone or in any combination.

[0016] In a preferred embodiment, each of the module frames is a beam frame.

Preferably, each of the module frames comprises four corner beams, in particular corner beams for forming modules. The corner beams of the module frames extend in the direction of the longitudinal axis of the module frame in question.

[0063] Figures 1 to 20Stages of a method according to an embodiment are shown, wherein an elevator is built into a destination location L from a plurality of prefabricated elevator modules A, B, C.

[0064] The method comprises manufacturing (also called prefabrication) a plurality of elevator modules A, B, C, in particular at a location remote from said destination location L, for example at a factory. Thus, they may not need to be manufactured on site where working conditions may not be optimal, but in an environment and conditions that can be more freely optimized to support accuracy, efficiency and ergonomics of the installation work. Such manufacturing at Figure 1-16 Shown in.

[0065] The manufacturing of a plurality of elevator modules A, B, C comprises: providing a module frame Fa, Fb, Fc having a longitudinal axis X, such as Figure 1 As shown. In the embodiment shown, each of the module frames Fa, Fb, Fc is a beam frame, which includes four corner beams 10a-10c for forming the corner beams of the modules A, B, C. The corner beams 10a-10c extend in the direction of the longitudinal axis X of the beam frame in question. Each of the module frames Fa, Fb, Fc also includes a plurality of cross beams 11a, 11b, 11c connecting the corner beams 10a, 10b, 10c to each other. In a preferred embodiment, the beams are metal beams. The metal beams are preferably tubular metal beams. Therefore, the beam frame is rigid and light, whereby large modules can be formed and lifted into place. The structure also reduces the forces to be borne when stacking, whereby high stacking of modules can be achieved. Preferably, the beam has one or more, preferably four, planar sides, whereby it is convenient to fix the elevator components to the beam.

[0066] In a preferred embodiment, the module frames Fa, Fb, Fc comprise a pit module frame Fa, at least one middle module frame Fb and a top module frame Fc.

[0067] The method comprises positioning one or more of the module frames Fa, Fb, Fc in a horizontal orientation position (also referred to as a horizontal position), wherein in said horizontal orientation position the longitudinal axis X of the module frame in question is horizontal. In the method, installation work is performed on one or more module frames Fa, Fb, Fc; Fa, Fb; Fb, Fc when the one or more module frames Fa, Fb, Fc; Fa, Fb; Fb, Fc are in a horizontal position, wherein in said horizontal orientation position the longitudinal axis X of the module frame is horizontal. The horizontal orientation position facilitates efficient, accurate and ergonomic performance of installation work. When in the horizontal orientation position, the module frame to be processed can be easily approached from all directions (including end directions and side directions), so that the installation work can be performed accurately, effectively and ergonomically. In particular, this contributes to the accuracy, efficiency and ergonomics of mounting components on the frame, adjusting the position of the beams of the frame, and accurately aligning the components to be fixed on the frame. The accessible side faces provide easy installation work from the side directions. The accessible ends provide for easy installation work from the end direction, in particular enabling the end-to-end connection of the module frames during the manufacturing phase and / or facilitating alignment work of components of the module frames or components to be fastened thereto.

[0068] The installation work can be performed on a single module frame Fa, Fb, Fc; Fa, Fb; Fb, Fc in a horizontal position, or can be performed on two (or more) module frames in a horizontal position and connected end to end to each other. The preferred steps of the installation work are Figure 2-16 Shown in.

[0069] After manufacturing a plurality of elevator modules A, B, C, for example by Fig.18 The truck T shown transports the modules A, B, C to the vicinity of the destination location L. Thereafter, the modules A, B, C are arranged one on top of the other in the destination location L so that each of the modules is in a vertical orientation position (also referred to as a vertical position, wherein in the vertical orientation position the longitudinal axis X of the module frame Fa, Fb, Fc of the module A, B, C is vertical). This has already been Figure 19-20 At least one middle module B including a middle module frame Fb and a top module C including a top module frame Fc. Fig.19 As shown, in the arrangement, modules A, B, C are arranged one on top of another in the destination position L, so that at least one middle module B is located on top of the pit module A, and the top module C is located on top of at least one middle module B.

[0070] In the following, reference Figure 2-16 The production of a plurality of elevator modules A, B, C is described in a more detailed manner.

[0071] like Figure 2 As shown, in a preferred embodiment, the manufacturing comprises positioning two module frames Fa, Fb in a horizontal orientation, in this case the pit module frame Fa and the intermediate module frame Fb, and then connecting the two module frames Fa, Fb to each other end to end while they are in a horizontal position. After the connection, installation work is performed on one or both of the two module frames Fa, Fb while they are in a horizontal position and connected to each other end to end. Figure 3-7 The preferred steps of the installation work are shown. It is advantageous to carry out the installation work on one or both of the two module frames Fa, Fb while the two module frames Fa, Fb are connected, because the installation work on the module frame can thus be carried out in the presence of the other module frame, since it is also intended to be in the final configuration to be built. As a result, for example, components of the module frames Fa, Fb and components fixed thereto can be positioned accurately relative to each other at an early stage, and the adjustment work required on site is reduced.

[0072] exist Figure 3 and Figure 4 In the embodiment of the present invention, when the two module frames Fa, Fb are in horizontal position and connected, this installation work performed on one or both of them consists in adjusting the position of the corner beams 10a-10c of the pit module frame Fa relative to each other and relative to the corner beams 10a-10c of the intermediate module frame Fb connected to the pit module frame Fa, and / or vice versa. To achieve the adjustment, the fixation between one or more beams 10a-10, 11a-11c of the individual module frames Fa, Fb is released and fixed again.

[0073] exist Figure 3 and Figure 4 In the embodiment, said adjusting position of the corner beams 10a-10c is performed so that the corner beams 10a-10c of the pit module frame Fa become aligned with the corner beams 10a-10c of the middle module frame Fb connected to the pit module frame Fa.

[0074] exist Figure 3In the method, the adjusting the position of the angle beams 10a-10c comprises adjusting the position of the angle beams 10a-10c, in particular by means of a laser beam 21, so that the angle beams become parallel or within a tolerance of deviation from parallelism. More specifically, the method comprises providing a laser device 20 and mounting a laser receiver component 22 on consecutive angle beams 10-10c in a straight line, emitting a laser beam 21 by means of the laser device 20, and adjusting the position of one or two of the consecutive angle beams so that the laser beam 21 irradiates the laser receiver component 22 to a corresponding position or at least within a tolerance of a corresponding position. The laser device 20 is preferably positioned in front of the end of the module frame Fa so as to emit the laser beam 21 from the end direction of the module frames Fa, Fb.

[0075] exist Figure 4 Said adjustment position of the corner beams 10a-10c is performed such that the cross-sectional dimensions C1 and C2 of the corner beams 10a-10c of the module frames Fa and / or Fb are changed, most preferably such that their length difference is reduced, wherein each cross-sectional dimension is the distance between diagonally opposite corner beams.

[0076] exist Figure 5-7 In the embodiment, when the two module frames Fa, Fb are in a horizontal position and connected to each other end to end, the installation work performed on one or both of the two module frames Fa, Fb includes fixing the elevator components 1, 2, 3, 4, 4a, 4b, 5b to at least one of the module frames Fa, Fb so that they are aligned with the corresponding elevator components 1, 2, 3, 4, 4a, 4b, 5b fixed to the other module frame Fa, Fb; Fb, Fc, which is connected to the module frame Fa, Fb; Fb, Fc in question. The elevator components 1, 2, 3, 4, 4a, 4b include one or more of the following: guide rail brackets 1 for guide rails 2 and / or 3; car guide rails 2; counterweight guide rails 3; landing door structure 4, in particular landing door frame components 4a and / or landing door leaves 4b. Examples of these are shown in FIG. Figure 5-7 Shown in.

[0077] exist Figure 5 In the embodiment, guide rail brackets 1 for guide rails 2 and / or 3 are fixed to module frame Fa so that they are aligned with the corresponding elevator components, i.e. guide rail brackets 1 for guide rails 2 and / or 3 are fixed to module frame Fb connected to the module frame Fa, Fb; Fb, Fc in question. This is performed with the aid of a laser device 20 emitting a laser beam 21. This can be achieved in various ways, but in Figure 5In the example of , this is performed so that alignment marks m are formed on the module frames Fa and Fb to multiple positions for indicating the expected positions of the brackets 1 to be fixed on the frames Fa and Fb. Thereafter, the brackets 1 can be fixed to these positions indicated by the marks m, whereby they will be aligned and fixed as described above. Alternative ways of aligning the corresponding components can be used. For example, the bracket 1 to be aligned can first be pre-fixed to two roughly aligned module frames F1, Fb, and then adjusted for alignment with the aid of a laser beam 21. The laser device 20 is preferably positioned in front of the end of the module frame Fa so as to emit the laser beam 21 from the end direction of the module frames Fa, Fb.

[0078] In the example shown, each of the brackets 1 can be fixed to the module frame, preferably by means of a screwable fixing device 1a, such as a screwable fixing device. The guide rails 2, 3 can preferably be fixed to each of the brackets 1, such as by means of a fastenable fixing nail 1b, so as to press the guide rails 2, 3 against a back plate 1c included in the bracket 1.

[0079] exist Figure 6 In the embodiment of the present invention, the guide rails 2 and 3 are fixed to the module frame Fa so that they are aligned with the corresponding elevator components (i.e. the guide rails 2 and 3) fixed to the module frame Fb connected to the module frame Fa. The alignment in this case results in an aligned positioning of the support 1. However, this fixing can alternatively be performed by means of a laser device 20 emitting a laser beam 21, in particular so that each guide rail can be individually adjusted to align according to the laser beam. This would be advantageous, for example, if for some reason it is chosen to omit the precise alignment step of the support 1.

[0080] exist Figure 7 In the embodiment, the landing door structure 4, in particular the landing door frame component 4a and / or the landing door leaf 4b, is fixed to the module frame Fa so that they are aligned with the landing door structure 4, in particular the landing door frame component 4a and / or the landing door leaf 4b, which is fixed to the module frame Fb connected to the module frame Fa. This is performed with the aid of a laser device 20 emitting a laser beam 21. This can be achieved in various ways, but in Figure 7 In the example of , this is performed so that the door frame parts 4a of the landing are individually adjusted to align according to the laser beam 21 and then fixed to the module frames Fa, Fb. The alignment of the landing door leaves 4b of consecutive landings in this case results in an aligned positioning of the frame parts 4a when these are fixed to the frame parts 4a. The laser device 20 is preferably positioned in front of the end of the module frame Fa so as to emit the laser beam 21 from the end direction of the module frames Fa, Fb.

[0081] like Figure 8As shown, the manufacturing includes: after the installation work is performed on one or both of the two module frames Fa, Fb, when the two module frames Fa, Fb are in a horizontal position and connected to each other end to end, disconnecting the two module frames Fa, Fb; separating from each other.

[0082] Already referenced Figure 2-7 The above-mentioned installation work is described as being performed on one or both of the two module frames Fa, Fb when they are connected, wherein the two module frames are the pit module frame Fa and the middle module frame Fb. The manufacture may additionally or alternatively include installation work performed in a corresponding manner on one or both of the two module frames Fb, Fc while the two module frames Fb, Fc are connected, wherein the two module frames are the middle module frame Fb and the top module frame Fc. Figure 9-10 This is shown.

[0083] like Fig. 9 As shown, here, the manufacturing includes positioning two module frames Fb, Fc in a horizontal orientation position, in this case, the two module frames Fb, Fc are a middle module frame Fb and a top module frame Fc, and then connecting the two module frames Fb, Fc to each other end to end when they are in a horizontal position, as shown. Fig.10 After said connection, installation work is performed on one or both of said two module frames Fb, Fc while they are in a horizontally oriented position and connected, the installation work being as described with reference to Figure 3-7 In particular, when the two module frames Fb, Fc are in a horizontally oriented position and connected, the installation work performed on one or both of the two module frames Fb, Fc preferably includes:

[0084] - adjusting the position of the corner beams 10c of the module frames Fc relative to each other and / or relative to the corner beams 10b of another module frame Fb connected to the module frame Fc; and / or

[0085] - fixing elevator components 1, 2, 3, 4, 4a, 4b, 5b on at least one of the module frames Fb, Fc so that they are aligned with corresponding elevator components 1, 2, 3, 4, 4a, 4b, 5b fixed to another module frame Fb connected to the module frame Fc in question, said elevator components 1, 2, 3, 4, 4a, 4b preferably comprising one or more of the following: guide rail brackets 1 for guide rails 2 and / or 3; car guide rails 2; counterweight guide rails 3; landing door structures 4, in particular landing door frame components 4a and / or landing door leaves 4b; and / or

[0086] - Aligning the alignment marks m on the module frames Fb, Fc to a plurality of positions for indicating the intended positions of the elevator components 1, 2, 3, 4, 4a, 4b to be fixed to the module frames Fb, Fc.

[0087] In the manufacturing example shown in the figure, the positions of the corner beams 10c of the frame modules Fa and Fb have been adjusted when they are connected, and the elevator components 1, 2, 3, 4, 4a, 4b, 5b have been installed on them when they are connected, which is already before the corresponding installation work is concentrated on the top module frame Fc. Therefore, the structure of the middle module frame Fb and the components fixed to the middle module frame Fb can be used as a reference for the installation work to be performed on the top module frame Fc. Therefore, it is advantageous that Figures 9 and 10 In the example shown, the fixing and adjustment are not performed on the two module frames Fb, Fc, but only on the parts 1, 2, 3, 4, 4a, 4b, 5b to be fixed to the top module frame Fc and the corner beams of the top module frame Fc.
