Description

The invention relates to a roof rack for a building phase elevator according to the preamble of claim 1.In the interior of a building with several floors, at least one elevator shaft is often provided for a building elevator or passenger elevator to be installed later. Such building elevators are usually self-propelled trains with the machine house and the cable suspension at the upper end of the shaft. Buildings of this type are usually erected from the bottom to the top, so that during the construction of the building the top of the building is not finished and therefore neither a cable suspension nor the machine house is available at the upper end of the building. For this reason, the building packing cannot be installed prematurely already during the building phase of the building. In addition, the construction work and the frequently occurring vandalism on construction sites would result in severe damage to the building packing, so that this building packing would have to be completely renewed after the end of the construction phase.It has therefore long been customary to provide a construction packing on the outside of the building being constructed, which construction packing also grows in height with the building.However, it is often necessary for a facade of the building still in the bodyshell to be closed already early in the construction phase, in order to enable a dry interior removal of already completed floors correspondingly early. An outer construction packing can then no longer be used.For this reason, it is already known to insert a so-called construction phase elevator into the already existing but still unused elevator shaft for the later building elevator or passenger elevator within the building, which is provided only for the construction phase of the building and has to be removed again after completion of the building, so that the final building elevator or passenger elevator can be installed. The construction phase elevator or its components are introduced, for example, with a crane from above into the not yet completed building into the open-top elevator shaft. A robust construction packing is thus available in the building. After completion of the building, however, the elevator shaft is no longer accessible from above and the construction elevator has to be dismantled from below and removed through conventional standard door openings 90 cm wide and 2 m high. For this purpose, it has been necessary up to now to saw the construction packing material-destroying into individual parts which fit through standard door openings of this type.If the build-phase elevator is to be used not only for transporting material but also for transporting persons, it is necessary to provide a car of the build-phase elevator with protection against falling objects. For this purpose, a roof that can be walked on by persons is to be provided, which usually is a very robust steel construction, which is formed in one piece and accordingly cannot be dismantled. This roof construction too is to be disassembled in a material-destructive manner for the disassembly of the construction phase elevator in order to remove it from the still present standard doors from the building.Construction elevators are usually made up in permanently predefined load categories, so that different models are necessary for different requirements concerning the weight or volume of conveyed goods to be transported and / or for different numbers of persons to be conveyed simultaneously. Although a modification for adaptation to respective circumstances of different construction sites would theoretically be possible, this is so complex that in practice this is only very rarely carried out. Instead, for each construction site, a different type of construction hoist is used which comes closest to the respective requirements.Since in conventional construction elevators the elevator car with elevator carriage and mast base element and possibly even the associated drive unit are a unit that can be separated only with great difficulty, the transport, the placement at the place of use and the storage are complicated and expensive.WO 2013 / 186420 A1 discloses a machine platform for a construction phase elevator for a building under construction. This machine platform contains all necessary installations for the elevator installation, such as cable suspension and drive, which are otherwise arranged in a machine house of a building elevator located at the top in the elevator shaft. The machine platform is movable along the elevator shaft, so that the usable lifting height of the build-phase elevator can grow together with the building and thus with the elevator shaft. However, this construction phase elevator also has to be laboriously removed from the elevator shaft again after the end of the construction phase by one of the lower floor openings of the elevator shaft, wherein this is located on the top floor at the time of the rear construction. Alternatively, the machine platform is removed before finishing the roof or the upper termination of the elevator shaft, but the construction phase elevator is then not available during the complete construction phase.The invention is based on the object of providing a roof cage for the stage of a construction phase elevator of the above-mentioned type. This is improved in that the stage can be mounted and modified easily, quickly and with little personnel even in confined spatial conditions.This object is achieved according to the invention by a roof cage for the stage of a construction phase elevator of the above-mentioned type. A method having the features characterized in claim 1 and sowi. Advantageous embodiments of the invention are described in the further claims.For this purpose, it is known from the above-mentioned case of a roof cage for the stage of a construction phase elevator. According to the invention, the roof rack is composed of a first U-shaped roof rack element and a second U-shaped roof rack element, which are plugged together on respective open sides of the U-shape and are telescopic relative to one another.This has the advantage that a walkable roof for the stage can be installed from the stage space.A particularly simple, functionally reliable and at the same time light construction for the roof rack is achieved in that the first and second roof rack elements are each formed with a U-shaped foot strip, a U-shaped railing and a U-shaped handrail.A simple construction for the telescopic function between the first and second roof basket elements with an access hatch accessible from the platform space is achieved in that the second roof basket element additionally has a roof basket base on a side of the foot strip of the second roof basket element facing away from the railing of the second roof basket element, and in that the first roof basket element is open on a side of the foot strip of the first roof basket element facing away from the railing of the first roof basket element.The invention is explained in more detail below with reference to the drawings.

The stage is composed of a central stage bottom member 18, stage bottom extension members 20 respectively fixed to the stage bottom member 18 and another stage bottom extension member 20, a plurality of first lower stage side members 22 respectively disposed on the stage bottom member 18 or one of the stage bottom extension members 20 arranged at the outermost, a plurality of first upper stage side members 24 respectively disposed on a first lower stage side member 22, a plurality of second lower stage side members 26 respectively disposed on a stage bottom extension member 20, a plurality of second upper stage side members 28 respectively disposed on a second lower stage side member 26, a plurality of stage roof members 30 respectively disposed on upper ends of first upper stage side members 24 and / or second upper stage side members 28, a roof basket 32, which rests on the one hand on upper ends of first upper stage side elements 24 and on stage roof traverses 38 (FIG. 4 ) and a vertically displaceable sliding door 34. The elevator shaft of the building located in the body shell is indicated in FIGS. 1 to 4 by a foundation 36. This elevator shaft later serves, during the interior removal of the building being installed, for installing a conventional building or passenger elevator, so that after completion of the body-in-white phase, the building phase elevator must be removed from the elevator shaft so that the final building or passenger elevator can be installed.As shown in FIG. 5, the installation of the construction phase elevator into the at least partially already present elevator shaft of a building located in the bodyshell begins with the mounting of the foot part 12 with the mast 10 and the elevator carriage 14 arranged displaceably thereon. Two fastening systems which are initially independent of one another and which are provided on the one hand on the platform base element 18 and on the other hand on the elevator carriage 14 serve for this purpose. One of these fastening systems provides a holder without further external holder devices in an assembly position merely by being hung in, and the other fastening system establishes a releasable force-fit and form-fit connection in the assembly position. This will be explained in more detail below with reference to FIGS. 7 to 13.As shown in FIGS. 7, 8, 10 and 11, the stage bottom member 18 has an upper side 40 facing the stage room in the mounting position of the stage bottom member 18, a lower side 42 facing away from the stage room in the mounting position of the stage bottom member 18, a first side 44 facing the elevator carriage in the mounting position of the stage bottom member 18, a second side 46 arranged opposite from, parallel to and spaced apart from the first side 44 of the stage bottom member 18, a third side 48 arranged perpendicular to the first side 44 and second side 46 of the stage bottom member 18, and a fourth side 50 arranged opposite from, parallel to and spaced apart from the third side 48 of the stage bottom member 18. On the first side 44 of the stage base element 18, two frame parts 52 are arranged spaced apart from one another in such a way that the stage base element 18 and the frame parts 52 are L-shaped. At each free end 54 of the frame parts 52 facing away from the stage bottom element 18, a first fastening element 56 and a second fastening element 58 are arranged. The first fastening element 56 of the stage base element 18 is designed as a hook which rises from the frame part 52 in the direction of the elevator carriage 14 and is open in the direction of gravity (arrow 92) when the stage base element 18 is in the mounting position. The second fastening element 58 of the stage base element 18 is designed as a screw bolt 60 with a screw nut 62, which is arranged laterally on the first fastening element 56 by a pivot joint 64.As can be seen from FIGS. 7, 8, 12 and 13, the elevator carriage 14 has a first stop element 66 and a second stop element 68. The two first stop elements 66 of the elevator carriage 14 are arranged and configured in such a way that a distance between the two first stop elements 66 of the elevator carriage 14 corresponds to a distance between the two first fastening elements 56 of the stage base element 18, so that when one of the first fastening elements 56 of the stage base element 18 is located in the region of one of the first stop elements 66 of the elevator carriage 14, the respective other first fastening element 56 of the stage base element 18 is automatically located on the other first stop element 66 of the elevator carriage 14. The first stop element 66 of the elevator carriage 14 is designed as a receiving pin or square pin rising from the elevator carriage 14, in particular in the form of a box profile. The second stop element 68 of the elevator carriage 14 is designed and arranged as a slot 70 at a free end of the first stop element 66 of the elevator carriage 14 facing away from the elevator carriage 14 in such a way that, when the stage base element 18 is suspended on the elevator carriage 14, the screw bolt 60 engages in the slot 70 by pivoting the screw bolt 60 about the pivot joint 64. In this way, a locking position is established between the second fastening element of the platform base element 18 and the second stop element of the elevator carriage 14.As can be seen from FIGS. 7 to 9, in this locking position, the pivot joint 64 is located on one side of the first stop element 66 of the elevator carriage 14 and the nut 62 of the second fastening element 58 of the stage base element 18 is located on an opposite side of the first stop element of the elevator carriage 14. Only a release of the first fastening element 56 of the stage base element 18, here exemplarily in the form of the hook, from the first stop element 66 of the elevator carriage 14, here exemplarily in the form of a box profile, is blocked. By combining the first fastening element 56 of the stage base element 18 with the first stop element 66 of the elevator carriage 14, a position of the stage base element 18 relative to the elevator carriage 14 which is releasable but fixed per se is thus produced in an assembly position, without, however, a force-fit and form-fit connection already being produced. This force-fit and form-fit connection can now be produced by tightening the nut 62 of the second fastening element of the 58 of the stage base element 18, wherein the nut 62 is supported on the first stop element 66 of the elevator carriage 14. Here, it is not necessary that the stage bottom member 18 is held in the mounting position relative to the elevator carriage 14 by external holders. The mounting of the platform base element 18 in the mounting position relative to the elevator carriage 14 is already produced by the suspension by means of the first fastening element 56 of the platform base element 18 onto the first stop element 66 of the elevator carriage 14.An unlocking position (not shown) for the second stop element 68 of the elevator carriage 14 and the second fastening element 58 of the stage base element 18 results from the fact that, when the nut 62 is loosened, that is to say without a force-fit and form-fit connection between the stage base element 18 and the elevator carriage 14, the bolt 60 is pivoted out of the slot 70 by the second stop element 68 of the elevator carriage 14 and the second fastening element of the stage base element 18. The engagement of the first fastening element 56 of the stage base element 18, here exemplarily in the form of the hook, in the first stop element 66 of the elevator carriage 14, here exemplarily in the form of a box profile, can now be released.As can be seen from FIGS. 14 to 18, the stage base extension element 20 has an upper side 72 which faces the stage space in the mounting position of the stage base extension element 20, a lower side 74 which faces away from the stage space in the mounting position of the stage base extension element 20, a first side 76 which faces the stage base element 18 in the mounting position of the stage base extension element 20, a second side 78 which is arranged opposite, parallel to and spaced apart from the first side 76 of the stage base extension element 20, a third side 80 which is arranged perpendicular to the first side 76 and second side 78 of the stage base extension element 20 and a fourth side 82 which is arranged opposite, parallel to and spaced apart from the third side 80 of the stage base extension element 20.As can be seen from FIG. 10, the second side 46, the third side 48 and the fourth side 50 of the stage base element 18 each have at least one third stop element 84 and at least one fourth stop element 86. In the embodiment shown, four third stop elements 84 each in the form of a recess and two fourth stop elements 86 each in the form of a screw bolt with a nut, which is pivotably fastened to the stage base element 18 by a pivot joint, are arranged on each of the sides 46, 48 and 50 of the stage base element 18. In an assembly position of the stage base element 18, the direction of gravity runs perpendicular to the upper side 40 and lower side 42 of the stage base element 18 and is directed in the direction of the lower side 42 of the stage base element 18, as indicated by arrow 92. In the embodiment shown, the fourth stop elements 86 of the stage base element 18 are formed analogously to the second fastening elements 56 of the stage base element 18 with the screw bolt, the screw nut and the pivot joint, as can be seen from FIG. 9, only with the difference that the respective pivot joint of the fourth stop elements 86 of the stage base element 18 is fastened to the lower and inner side 42 of the stage base element 18.As can be seen from FIGS. 14 to 18, the stage base extension element 20 has at least one third fastening element 88 and at least one fourth fastening element 90 on the first side 76 of the stage base extension element 20. In the illustrated embodiment, four third fasteners 88 and two fourth fasteners 90 are disposed on the first side 76 of the stage bottom extension member 20. The third attachment elements 88 of the stage bottom extension element 20 are each designed in the form of a hook which rises from the first side 76 of the stage bottom extension element 20 and is open in the direction of the underside 74 of the stage bottom extension element 20. The fourth attachment members 90 of the stage bottom extension member 20 are each formed in the form of two parallel plates 94 that rise from the first side 76 of the stage bottom extension member 20 and form a gap therebetween. In an assembly position of the stage bottom extension element 20, the direction of gravity runs perpendicular to the upper side 72 and lower side 74 of the stage bottom extension element 20 and is directed in the direction of the lower side 74 of the stage bottom extension element 20, as indicated by arrow 92.Each third fastening element 88 of the stage base extension element 20 and each third stop element 84 of the stage base element 18 are arranged and configured such that, in an assembly position of the stage base extension element 20 relative to the stage base element 18, a third fastening element 88 of the stage base extension element 20 engages in a positive-locking manner in a third stop element 84 of the stage base element 18, such that the hooks of the third fastening elements 88 of the stage base extension element 20 engage in or are hooked into the recesses of the third stop elements 84 of the stage base element 18. In this way, the stage base extension element 20 is suspended with its third fastening elements 88 on the third stop elements 84 of the stage base element 18 in the mounting position in such a way that the stage base extension element 20 is detachably fastened and fixed to the stage base element 18 by the action of gravity or by means of shear force locking. In this case, the stage base extension element 20 faces the stage base element 18 on its third side 48 or fourth side 50 with its first side 76.The terms "gravity locking" or "fastened and fixed in a releasable manner by the action of gravity" or "fastened and fixed in a releasable manner by the action of gravity" between a first and a second component here mean that the own weight of one of the components involved carries out a fixing, which can however be released again by lifting this component counter to the direction of gravity. An example of such a connection is a hook-type or snap-in plug-type connection, in which the dead weight of the hooked-in or snap-in component ensures stability without additional screws or other fixing means being necessary.In this releasably secured mounting position between the stage bottom extension member 20 and the stage bottom member 18, the fourth attachment members 90 of the stage bottom extension member 20 further pass through respective openings in the first side 48 of the stage bottom member 18 where the fourth stop members 86 of the stage bottom member 18 are located. After the stage bottom extension member 20 is hooked to the stage bottom member 18 as described above, the bolt of the fourth stop member 86 of the stage bottom member 18 is in an unlocked position in which it is spaced from the plates 94 of the respective fourth attachment member 90 of the stage bottom extension member 20.The bolts of the fourth stop elements 86 of the stage base element 18 are accessible from the stage space through respective openings 96 on the upper side 40 of the stage base element 18 and can thus be pivoted manually into a locking position in which the bolt of each fourth stop element 86 of the stage base element 18 is located in a position in the gap between the two plates 94 of the respective fourth fastening element 90 of the stage base extension element 20. Here, the nut of the fourth stopper member 86 of the stage bottom member 18 and the pivot joint of the fourth stopper member 86 of the stage bottom member 18 are disposed on opposite sides of the plates 94 of the respective fourth fixing member 90 of the stage bottom extension member 20. In this way, a lifting of the stage base extension element 20 counter to the direction of gravity (arrow 92) is already blocked as a result, so that the engagement between the third fastening elements 88 of the stage base extension element 20 and the third stop elements 84 of the stage base element 18 is blocked against detachment. If the nuts of all fourth stop elements 86 of the stage base element 18 are now additionally tightened, a force-fit and form-fit connection is produced between the stage base extension element 20 and the stage base element 18.The second side 78 of the stage bottom extension element 20 has at least one third stop element 84 awhich is designed and arranged identically to the at least one third stop element 84 of the stage bottom element 18. The second side 78 of the stage bottom extension element 20 further comprises at least one fourth stop element 86 awhich is configured and arranged identically to the at least one fourth stop element 86 of the stage bottom element 18. In the illustrated preferred embodiment, four third stopper members 84 aof the stage bottom extension member 20 and two fourth stopper members 86 aof the stage bottom extension member 20 are disposed at identical positions as the four third stopper members 84 of the stage bottom member 18 and the two fourth stopper members 86 of the stage bottom member 18. In this way, it is possible for a further stage base extension element 20 to be arranged on the second side 78 of the stage base extension element 20 with the first side 76 thereof and to be fastened in a force-fit and form-fit manner. This is effected analogously to the fastening of the stage base extension element 20 to the stage base element 18 described above.As can be seen from FIGS. 14 to 19, at least one further third stop element 84 aand at least one further fourth stop element 86 aare arranged in each case on the third side 80 of the stage bottom extension element 20 and on the fourth side 82 of the stage bottom extension element 20. In the embodiment shown, two third stop elements 84 aand one fourth stop element 86 aare arranged in each case on the third side 80 and on the fourth side 82 of the stage bottom extension element 20.For each fourth stop element 86 aof the stage base extension element 20, an opening 96 is provided on the upper side 72 of the stage base extension element 20, through which the respective fourth stop element 86 aof the stage base extension element 20 is accessible and can be operated manually from the stage space, i.e. can be pivoted manually in such a way that it is optionally in a locking or unlocking position.The fourth stop elements 86 aof the stage base extension element 20 are formed analogously to the second fastening elements 58 of the stage base element 18 with a screw bolt 60 awith a screw nut 62 aand with a pivot joint 64 a. The pivot joints 64 aof the fourth stop elements 86 aof the stage bottom extension element 20 are connected to the stage bottom extension element 20 at the lower side 74 of the stage bottom extension element 20. As a result, the screw bolts 60 aof the fourth stop elements 86 aof the stage base extension element 20 can be selectively pivoted into a locking position and an unlocking position in a similar manner to the screw bolts 60 of the second fastening element 58 of the stage base element 18 or as the screw bolts of the fourth stop elements 86 of the stage base element 18.As can be seen from FIGS. 20 to 22, the first lower stage side element 22 has the following: an inner side 98 which faces the stage space in the mounting position of the first lower stage side element 22, an outer side 100 which faces away from the stage space in the mounting position of the first lower stage side element 22, a first side 102 which faces a stage base element 18 or a stage base extension element 20 in the mounting position of the first lower stage side element 22, a second side 104 which is arranged opposite from, parallel to and spaced apart from the first side 102 of the first lower stage side element 22, a third side 106 which is arranged perpendicular to the first side 102 and second side 104 of the first lower stage side element 22, and a fourth side 108 which is arranged opposite from, This is disposed parallel to and spaced from the third side 106 of the first lower stage side member 22.At the first side 102 of the first lower stage side element 22, at least one third fastening element 88 ais arranged, which is formed and arranged on the inside of the first lower stage side element 22 identically to the third fastening element 88 of the stage bottom extension element 20. In the illustrated embodiment, four third mounting members 88 aof the first lower stage side member 22 are provided. Each third attachment member 88 aof the first lower stage side member 22 rises in the shape of a hook from the inner side 98 of the first lower stage side member 22.The first lower stage side element 22 is suspended on the at least one third stop element 84 of the stage bottom element 18 on the second 46, third 48 or fourth side 50 of the stage bottom element 18 or on the at least one third stop element 84 aof the stage bottom extension element 20 on the second side 78 of the stage bottom extension element 20 in the mounting position of the first lower stage side element 22 in such a way that the first lower stage side element 22 is releasably fastened and fixed to the second 46, third 48 or fourth side 50 of the stage bottom element 18 or to the second side 78 of the stage bottom extension element 20 by the action of gravity or by the action of gravity.The first side 102 of the first lower stage side element 22 further comprises at least one fourth fastening element 90 a, which is formed and arranged on the inner side 98 of the first lower stage side element 22 identically to the fourth fastening element 90 of the stage bottom extension element 20. In the illustrated embodiment, two fourth mounting members 90a of the first lower stage side member 22 are provided.

In the embodiment shown, two third fastening elements 88 bof the second lower stage side element 26 are provided, which, analogously to the third fastening element 88 of the stage bottom extension element 20, is designed in the form of a hook which is open in the direction of the first side 134 of the second lower stage side element 26.The second lower stage side member 26 is hinged to the third stopper member 84 aof the stage bottom extension member 20 on the third side 80 or the fourth side 82 of the stage bottom extension member 20 in the mounting position of the second lower stage side member 26 with the third fixing member 88 bof the second lower stage side member 26 such that the second lower stage side member 26 is detachably fixed and fixed to the third side 80 or the fourth side 82 of the stage bottom extension member 20 in the mounting position by gravity,At the first side 134 of the second lower stage side element 26, at least one fourth fastening element 90 bis also provided, which is formed on the inner side 130 of the second lower stage side element identically to the fourth fastening element 90 of the stage base extension element 20. In the illustrated embodiment, a fourth attachment member 90 bis provided centrally on the first side 134 of the second lower stage side member 26. This fourth fastening element 90 bof the second lower stage side element 26 has two plates 94 b,which rise from the inner side 130 of the second lower stage side element 26 and form a gap therebetween.The second lower stage side element 26 can be detachably connected in a force-fit and form-fit manner to the fourth fastening element 90 bof the second lower stage side element 26 on the fourth stop element 86 aof the stage base extension element 20 on the third side 80 or the fourth side 82 of the stage base extension element 20 in the mounting position of the second lower stage side element 26.In a locking position of the engagement between the fourth stop element 86 aof the stage bottom extension element 20 and the fourth fastening element 90 bof the second lower stage side element 26, the disengagement between the third stop element 84 aof the stage bottom extension element 20 and the third fastening element 88 bof the second lower stage side element 26 is blocked. This locking position is achieved by a corresponding pivoting of the screw bolt 60 aof the fourth stop element 86 aof the stage base extension element 20, such that the screw bolt 60 aof the fourth stop element 86 aof the stage base extension element 20 is located or extends within the gap between the plates 94 b. Here, the nut 62 aand the pivot joint 64 aare located on opposite sides of the two plates 94 b,so that, with this locking position alone and regardless of whether the nut 62 ais tightened or not, disengagement between the third stop element 84 a(in the form of the slot) of the stage bottom extension element 20 and the third fastening element 88 b(in the form of the hook) of the second lower stage side element 26 is blocked. Only by tightening the nut 62a is the force-fit and form-fit connection established between the second lower stage side element 26 and the stage bottom extension element 20. The pivot of the bolt 60 aand the tightening of the nut 62 acan be performed manually from the stage room through the opening 96 aon the upper side 72 of the stage bottom extension member 20. In this way, it is not necessary for access to be provided from outside the stage space for assembly and disassembly. This is the case above all when the construction phase elevator is mounted and disassembled in an elevator shaft of a body shell of a building being constructed. As a result of the narrowness of the elevator shaft, access from outside the platform space is generally not provided.In an unlocked position of the engagement between the fourth stop element 86 aof the stage bottom extension element 20 and the fourth fastening element 90 bof the second lower stage side element 26, the engagement between the third stop element 84 aof the stage bottom extension element 20 and the third fastening element 88 bof the second lower stage side element 26 is releasable. The unlocking position is achieved in that, when the nut 62 aof the fourth stop element 86 aof the stage base extension element 20 is loosened, the bolt 60 aof the fourth stop element 86 aof the stage base extension element 20 is pivoted in such a way that it is located outside the gap between the two plates 94 bof the fourth fastening elements 90 bof the second lower stage side element 26. In this way, the nut 60 aof the fourth stopper member 86 aof the stage bottom extension member 20 no longer blocks raising of the second lower stage side member 136 against the gravity, so that the third fastening members 88 bof the second lower stage side member 26 can be released from engagement with the third stopper members 84 aof the stage bottom extension member 20 and the second lower stage side member 26 can be removed from the mounting position.The second side 136 of the second lower stage side member 26 further includes at least a seventh stop member 142. In the embodiment shown, two seventh stop elements 142 of the second lower stage side element 26 are provided on the second side 136 of the second lower stage side element 26. The seventh stop element 142 of the second lower stage side element 26 is formed as a receiving opening for a pin in the second side 136 of the second lower stage side element 26.The second side 136 of the second lower stage side member 26 further includes at least one eighth stop member 144. In the illustrated embodiment, an eighth stop member 144 of the second lower stage side member 26 is provided. The eighth stop element 144 of the second lower stage side element 26 is formed as a through bore in the second side 136 of the second lower stage side element 26.As shown in FIGS. 27 to 29, the second upper stage side member 28 has an inner side 146 facing the stage room in the mounting position of the second upper stage side member 28, an outer side 148 facing away from the stage room in the mounting position of the second upper stage side member 28, a first side 150 facing a second lower stage side member 26 in the mounting position of the second upper stage side member 28, a second side 152 disposed opposite, parallel to, and spaced apart from the first side 150 of the second upper stage side member 28, a third side 154 disposed perpendicular to the first side 150 and to the second side 152 of the second upper stage side member 28, and a fourth side 156, which is disposed parallel to and spaced from the third side 154 of the second upper stage side member 28.At least one seventh fastening element 158 is arranged on the first side 150 of the second upper stage side element 28, with which fastening element the second upper stage side element 28 is plugged onto the second lower stage side element 26 in the mounting position of the second upper stage side element 28 in such a way that the second upper stage side element 28 is detachably fastened and fixed to the second lower stage side element 26 by gravity action or gravity locking. In the illustrated embodiment, two seventh attachment members 158 of the second upper stage side member 28 are provided. The seventh attachment elements 158 of the second upper stage side element 28 are each designed as pins which rise from the first side 150 of the second upper stage side element 28 and fit into the seventh stop elements 142 of the second lower stage side element 26 in the form of the receiving openings for a pin in the second side 136 of the second lower stage side element 26.At least one eighth fastening element 160 is arranged on the first side 150 of the second upper stage side element 28, with which fastening element the second upper stage side element 28 can be detachably connected in a force-fit and form-fit manner to the second lower stage side element 26 in the mounting position of the second upper stage side element 28. In the illustrated embodiment, an eighth attachment member 160 of the second upper stage side member 28 is provided on the first side 150 of the second upper stage side member 28. This is formed as a through bore on the first side 150 of the second upper stage side element 28. In an assembly position of the second upper stage side element 28 on the second lower stage side element 26, an eighth fastening element 160 of the second upper stage side element 28 is aligned with an eighth stop element 144 of the second lower stage side element 26.In a locking position of the engagement between the eighth stop element 144 of the second lower stage side element 26 and the eighth fastening element 160 of the second upper stage side element 28, the disengagement of the seventh fastening element 158 of the second upper stage side element 28 with the seventh stop element 142 of the second lower stage side element 26 is blocked. In the embodiment shown, this locking position is produced, for example, by inserting a threaded bolt through an eighth stop element 142 of the second lower stage side element 26 and an eighth fastening element 160 of the second upper stage side element 28 aligned therewith, and screwing on and tightening a nut onto this threaded bolt.In an unlocked position between the eighth stop element 144 of the second lower stage side element 26 and the eighth fastening element 160 of the second upper stage side element 28, the engagement between the seventh fastening element 158 of the second upper stage side element 28 and the seventh stop element 142 of the second lower stage side element 26 is releasable. The unlocking position is achieved by unscrewing the nut from the threaded bolt and removing the threaded bolt.On the second side 152 of the second upper stage side element 28, in a similar manner to the second side 136 of the second lower stage side element 26, there are likewise provided seventh stop elements 142 aof the second upper stage side element 28 and eighth stop elements 144 aof the second upper stage side element 24, which stop elements serve for plugging in or connecting to corresponding seventh fastening elements 158 of the second upper stage side element 28 and eighth fastening elements 160 of the second upper stage side element 28 of a further first upper stage side element 28. In this way, the side wall with a plurality of second upper stage side elements 28 inserted one on top of the other can be extended in height as desired.Ninth fastening elements 200 in the form of passage bores are arranged in the third and fourth side walls 106 and 108 of the first lower stage side element 22, in the third and fourth side walls 122 and 124 of the first upper stage side element 24, in the third and fourth side walls 138 and 140 of the second lower stage side element 26 and in the third and fourth side walls 154 and 156 of the second upper stage side element 28. In an assembly position of the elements 22, 24, 26 and 28, these are aligned with ninth fastening elements 200 of a respectively adjacent element 22, 24, 26 and 28, so that corresponding screw bolts can be inserted through these and force-fit and form-fit connections can be produced between adjacent elements 22, 24, 26 and 28 with screwed-on screw nuts.Figs. 30 to 33 show a preferred embodiment of the roof basket 32 according to the invention. A first U-shaped roof rack member 162 includes a first U-shaped foot bar 164, a first U-shaped handrail 166, and a first U-shaped handrail 168. A second U-shaped roof rack member 170 includes a second U-shaped foot bar 172, a second U-shaped handrail 174, and a second U-shaped handrail 176.As can be seen from FIG. 30, in the illustrated exemplary embodiment of the roof rack 32 according to the invention, the U-shape of the first and second foot strips 164 and 172, the first and second railings 166 and 174, and the first and second handrails 168 and 176 of the two roof rack elements 162 and 170 is in each case formed from two limbs 216, having a respective free end 218 and a base side 220 which connects the limbs 216 to one another on opposite sides of the free ends 218 of the limbs 216. The first and second handrails 166 and 174 further include vertical supports 222 that respectively connect the first handrail 168 and the first foot bar 164 of the first roof rack member 162 and the first handrail 176 and the first foot bar 172 of the second roof rack member 170, respectively.The first roof rack element 162 has a predetermined first distance 210 between the legs 216 of the U-shaped first rail 166 of the first roof rack element 162 or the legs 216 of the U-shaped first handrail 168 of the first roof rack element 162 or the legs 216 of the U-shaped first foot strip 164. Furthermore, the second roof rack element 170 has a predetermined second distance 212 between the legs 216 of the U-shaped second rail 174 of the second roof rack element 170 or the legs 216 of the U-shaped second handrail 176 of the second roof rack element 170 or the legs 216 of the U-shaped second foot strip 172 of the second roof rack element 170.The first distance 210 is smaller than the second distance 212. In this way, the first roof basket element 162 is formed somewhat narrower than the second roof basket element 170, so that the first roof basket element 162 can be pushed with its open end into the open end of the second roof basket element 170. In this case, the first roof basket element 162 can be inserted into the first roof basket element 170 until the first railing 166 of the first roof basket element 162 abuts with its free end 218 against the railing 174 of the second roof basket element 170 or its base side 220. In this way, a spatial dimension of the roof cable 32 is smaller than an opening between the stage side members at an upper side of the stage room at least in one dimension.In such an inserted state, the roof basket 32 can thus be inserted through an opening defined by the stage side elements first laterally into the stage space and then be pushed on the top side of the stage through a corresponding further opening between the stage side elements by means of corresponding tilting. Above the side elements of the stage, the two roof basket elements 162 and 170 are then pulled apart again until they reach an assembly position which is illustrated in FIGS. 30 to 32 and are placed on the side elements of the stage. In the illustrated embodiment, the roof rack 32 is placed on the first and second upper stage side members 16 and 28. The remaining space between the stage side members and adjacent the roof basket 32 is closed with the stage roof members 30. In this way, the top of the stage room is completely closed and persons inside the stage room are protected from falling objects.Corresponding through-holes are provided in the parapets 166 and 174 and the handrails 168 and 176 of the two roof basket elements 162 and 170, which, in the installation position of the roof basket 32, as shown in FIGS. 30 to 32, are aligned with one another, so that corresponding screw bolts 180 can be inserted through and fixed in a force-fitting and form-fitting manner with correspondingly screwed-on screw nuts.For further closing the roof of the platform space, the second roof basket element 170 has a roof basket base 178. As can be seen directly from FIGS. 30 and 31, a region on the bottom of the roof basket 32 thus remains open in the mounting position of the roof basket 32. This serves as an access hatch from the platform space to the roof basket 32 and is closed by a corresponding roof hatch construction, not shown in FIGS. 30 and 31, with a pivotable hatch.The locking position explained above for different connections does not necessarily yet produce a force-fit and form-fit connection. Rather, by pivoting the screw bolt into the slot or gap with the screw nut preferably arranged captive thereon, initially only loosening of the plug connection is blocked. Only by tightening the screw nut is the force-fit and form-fit connection established.FIG. 34 shows the respective mounting positions of the stage bottom member 18, the stage bottom extension members 20, the first lower stage side members 22, and the second lower stage side members 26. Respective second upper stage side elements 28 (not shown in FIG. 34 ) are plugged in their mounting position onto the upper sides 136, visible in FIG. 34, of the second lower stage side elements 26.The essential difference between the first stage side elements 22, 24 and the second stage side elements 26, 28 is that they are adapted in their width to different sides of the stage base element 18 and of the stage base extension element 20, respectively. The first stage side members 22 and 24 are widthwise matched to the second side 46, third side 48 and fourth side 50 of the stage bottom member 18, and the second side 78 of the stage bottom extension member 20. The second stage side members 24 and 26 are widthwise matched to the third side 80 and fourth side 82 of the stage bottom extension member 20. In the illustrated embodiment, the third side 80 and fourth side 82 of the stage bottom extension member 20 are the same width but narrower than the second side 46, third side 48 and fourth side 50 of the stage bottom member 18 and the second side 78 of the stage bottom extension member 20, and further the second side 46, third side 48 and fourth side 50 of the stage bottom member 18 and the second side 78 of the stage bottom extension member 20 are the same width.The build-phase elevator shown by way of example achieves a simple modular system for the stage of the build-phase elevator, with which system the stage can be designed in a wide variety of ways. The modification of the design of the stage is not limited to the first-time production process, but can also be carried out quickly and easily later by the user of the build-phase elevator at the place of use of the build-phase elevator. The arrangement of the roof basket 32 according to the invention on the top side of the stage can likewise be varied.References included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
