Definitions

  • the invention relates to a method for driving on the facade of a building with the gondola of a facade elevator according to the preamble of claim 1 and a facade elevator for performing this method.
  • Facade lifts which are required, for example, for cleaning window surfaces or for repair work on the facade, particularly in high-rise buildings, have been known for many years.
  • a facade elevator is described in DE 33 20 010 C1
  • the gondola hanging on support cables can be raised and lowered parallel to the facade surface by a lifting device mounted on a roof trolley.
  • the gondola is designed as a cantilever gondola and hangs with its supporting cables on an additional boom of the lifting device which can be rotated about a vertical axis. This makes it possible to reach the underlying areas of the facade from the correspondingly turned cantilever gondola in the case of overhanging facade parts.
  • a facade elevator In many countries it is mandatory, at least for certain building heights, that a facade elevator must be secured against the gondola swinging away from the facade surface. This swinging away can easily occur, especially with large building heights due to wind forces.
  • Such securing usually looks like that a number of vertically running guide rails are arranged on the facade, each of which marks a lane of the gondola, which is also referred to below as the access line.
  • guide wheels or castors can engage, which are firmly connected to the nacelle and, among other things, can also absorb tensile and compressive forces perpendicular to the facade surface.
  • the nacelle can be held securely at a fixed distance from the surface of the facade and at the same time can be moved up and down in the vertical direction.
  • the guide rollers For a horizontal movement over the facade, the guide rollers must be disengaged from the guide rail.
  • the object of the invention is to provide a method for driving on any, but in particular inclined facade surfaces with a facade lift gondola, in which swinging away of the gondola from the facade surface beyond an unacceptable amount is reliably avoided without using guide rails.
  • a device for performing this method is to be specified.
  • the solution principle of the invention consists in that at least one, preferably two guide ropes are carried in the gondola of the facade elevator, which at the beginning of a travel operation from the already pivoted out gondola, i.e. approximately parallel to the roof top edge of the respective building, with one end at predetermined fixed points on the Building facade can be releasably attached.
  • a number of test fasteners are connected to the facade at a distance from one another along the respective access line.
  • This drive line generally corresponds essentially to a fall line of the facade surface, but can, if necessary, also have lateral bends or even horizontal sections, so that a lifting or lowering process of the gondola does not have to run strictly along a fall line.
  • the guide rope or ropes are successively connected to the individual fastening elements by connecting elements in such a way that each guide rope is in the area of the fastening elements is fixed in the horizontal direction.
  • a holding device is provided on the nacelle for each guide rope, which holds the guide rope when the nacelle is at a standstill and releases it when lifting and lowering or other processes.
  • the respective guide rope transfers its horizontal fixation to the nacelle accordingly.
  • the fixing of the gondola is tighter, the closer the gondola is to the next fastening element, that is, the closer the fastening elements of an access line are to each other.
  • the fastenings between the guide rope and fastening elements are successively released again in a corresponding manner, and the guide rope can be picked up again by the gondola. Finally, the guide rope is also released from the respective fixed point and completely removed from the facade.
  • FIG. 1 The schematic representation of a facade elevator according to the invention in FIG. 1 shows a building, the facade of which has 5 vertical and additionally inclined (below and above 90 °) partial areas.
  • the lifting device 1 of the facade elevator On the roof of the building, the lifting device 1 of the facade elevator is mounted on a roof trolley 15 which can be moved without rails or on rails.
  • the lifting device 1 could alternatively also be test standing and equipped with an extendable boom that can be pivoted about a vertical axis.
  • a gondola 3 of the facade elevator can be lifted and lowered on the suspension cables 2 by the lifting device 1 and can be moved horizontally by the roof trolley 15: a series of fastening elements 6 are arranged on the facade 5 along the selected travel line at a distance from one another.
  • the fastening elements 6 are distributed over the entire facade surface.
  • At least one guide rope 7 (preferably two guide ropes) is carried in the nacelle 3, which will be discussed in more detail below, which at the beginning of the travel operation fixes one end 8 from the nacelle 3 which has already been swung out to the upper area of the facade 5 but was releasably connected to the top fastener 6.
  • the guide rope 7 was fixed to the fastening elements 6 in the horizontal direction by means of connecting elements (not shown in FIG. 1).
  • FIGS. 2 and 3 show possible embodiments of suitable fasteners 6 and connecting elements.
  • the fastening element 6 firmly anchored in the facade 5 consists of a short, rigid steel sheet with an eyelet 14.
  • a snap hook was latched into this eyelet 14 as a connecting element 10a, which at the same time also encloses the guide rope 7 and thus fixes it in the horizontal direction.
  • the snap hook 10a like the guide rope 7, is carried along by the nacelle 3, so it is not permanently attached to the building facade 5, but is only manually latched in when necessary when driving onto the facade 5 (forward travel).
  • FIG. 3 An alternative is shown in FIG. 3, in which the fastening element 6 and the connecting element (in the form of a snap hook 10b) are structurally integrated into a single piece.
  • This design has the advantage that, apart from the guide rope t, no further loose parts have to be carried in the nacelle 3.
  • the fastening elements 6 permanently remaining on the facade 5 are overall somewhat larger and thus possibly somewhat more clearly recognizable from the outside. Other shapes for the fasteners 6 are possible.
  • the gondola 3 of the facade elevator according to the invention shown in FIGS. 4 and 5 is suspended from support ropes (not shown) which are fastened to columns 17 which are firmly connected to the gondola body and are arranged on the two narrow sides of the gondola 3.
  • rolling elements 4 are arranged on the outside for direct support of the gondola 3 on the surface of the facade 5 without the interposition of a special support device such as a guide rail.
  • a special support device such as a guide rail.
  • rolling elements 4 soft, large-area sliding elements could in principle also be used, but here the danger of scratch marks on the facade 5 would be more likely.
  • the rolling elements 4 are roller-shaped, that is to say with a considerable length expansion and, moreover, are made of a soft material (e.g. foam plastic) in order to ensure a large-scale contact with the facade 5 and to keep the resulting surface pressure as low as possible. This prevents damage to the facade, for example, which could otherwise occur with small contact surfaces if the nacelle e.g. is strongly pressed against the facade 5 by wind forces.
  • a soft material e.g. foam plastic
  • the gondola 3 could also be equipped with a plurality of rolling elements 4, at least one in the upper and at least one in the lower region of the gondola 3, in order to make direct contact with the outer wall at any type of slope in the facade the gondola 3 with the example facade 5 made of glass and aluminum parts to be avoided safely.
  • the guide rope 7 is guided in each case by a holding device 9 which is fixedly connected to the nacelle 3 and has a carrier piece 22.
  • the carrier piece 22 is in each case attached to the outside of the tubular column 17, an advantageous development of the invention being a releasable connection in the form of a Clamp connection is provided.
  • the height adjustment 18 created in this way enables the height of the holding device 9 to be changed relative to the upper edge of the nacelle 3 along the column 17.
  • the holding device 9 is constructed on a tubular support 20, for example, which, in an advantageous further development of the invention, in turn has a releasable clamping connection - Is attached to the support piece 22. This also creates a horizontal adjustment 21 for the holding device 9, so that the distance between the hanging gondola 3 and the facade surface, for example in the area of overhanging facade parts, can be changed as required.
  • the guide rope 7, which is guided by a clamping device 11 mounted on the carrier 20, is clamped.
  • the clamping of the guide cable 7 can be released again by an unlocking device 12, so that the guide cable 7 can slide freely through the clamping device 11.
  • the clamping device 11 or the unlocking device 12 should be connected to the control of the lifting device 1 and the roof vehicle 15 in a signaling manner in such a way that the nacelle 3 can be raised or lowered or otherwise moved in the sense of a dead man's switch only if the clamping device 11 is released, so not stuck.
  • the clamping force of the clamping device 11 is also recommended for safety reasons to limit the clamping force of the clamping device 11. This should be kept at least so low that, in the event of a malfunction with undissolved clamping device 11, getting stuck and thus a possible inclination of the nacelle when lowering by the support cables 2 is impossible, i.e. that the gondola can overcome the clamping force of the clamping devices 11 due to its weight and thus the guide cables slide through the clamping devices 11 in operation.
  • the clamping force of the clamping devices 11 must be at least so great that the forces which may occur and which the gondola 3 seeks to push away from the facade 5 are safely controlled.
  • the guide rope 7 is guided over deflection rollers 19a and 19b in a material-saving manner through the holding device 9.
  • the holding devices 9 are expediently equipped with limit switches 13 which immediately interrupt the activity of the lifting device 1 or of the roof vehicle 15 when they strike against such a fastening element 6.
  • the holding device 9 is designed in an advantageous further development of the invention in the sense of a cardanic joint in order to ensure that the rope is guided as gently as possible in the event of a change in the angle between the incoming guide rope 7 and the axis of the carrier 20. It is furthermore expedient to carry the guide rope 7 on a winding device 16 (for reasons of space) arranged on the outside of the nacelle 3 and designed as a rope drum. Of course, the guide rope 7 can also hang freely down from the holding device 9 along the facade 5.
  • the winding device 16 can be operated manually or by a motor (e.g. by means of a power tool with an accumulator).
  • the guide roller 19b is pivotally mounted in the illustrated embodiment about an axis parallel to the longitudinal axis of the carrier 20.
  • a plastic in particular a nylon material
  • the nacelle 3 is also held close to the facade 5 by the guide rope 7, which runs above the nacelle 3 through a plurality of fastening elements 6 at approximately the same narrow distance from the facade 5 and does not swing away to the outside or to the side can. Rather, the nacelle 3 is pulled towards the facade surface in the overhanging facade part, so that the rolling elements 4 always lie directly on the facade 5. Because of the foam plastic used for the rolling elements 4, there is no damage (e.g. scratches) on the facade surface.
  • FIG. 6 From the schematic representation of FIG. 6, in which parts having the same function have the same reference numerals as in FIGS. 1 to 5, it can be seen that the facade elevator according to the invention is suitable not only for driving on a facade 5 in the vertical direction, but also also in the horizontal direction.
  • the building shown has a stepped profile in side view.
  • the arrows shown indicate that the nacelle 3 has reached the position shown in a stepped movement.
  • the two ends 8 of the guide ropes 7 (drawn in dashed lines) were firmly connected to the uppermost fastening elements 6 (each indicated by a dot) in the same way as in FIG. 1.
  • the nacelle 3 was lowered vertically, the guide cables 7 being latched into two further fastening elements 6 each.
  • the gondola 3 about the height of the first had reached the lowered level of the facade 5, it was moved horizontally to the right, while the guide cables 7 were connected in a corresponding manner to further fastening elements 6.
  • the horizontal movement of the nacelle 3 can be realized, for example, by a corresponding method of the roof trolley 15 or also by an extendable boom of the lifting device 1.
  • the cardanic suspension already described (FIG. 5) in the region of the cable pulley 19a of the holding device 9 enables problem-free adaptation to the changing direction (vertical / horizontal) of the attached guide cables 7.
  • the safety-related mentioned above in the course of the description of FIGS Coupling (dead man's switch) between the clamping and unlocking devices of the holding devices 9 on the one hand and the control of the lifting device 1 on the other hand naturally also includes the control of the horizontal movement of the nacelle 3. A horizontal movement can therefore also only take place if the clamping devices door, the guide cables 7 are released.
  • a second vertical driving phase follows in the manner shown, then again a horizontal and finally another vertical driving phase.
  • the solution according to the invention also makes it possible to carry out simultaneous vertical and horizontal movements of the nacelle 3 with constant securing by the guide cables 7. Since a large number of fastening elements 6 can be attached to the facade 5, almost arbitrarily designed access routes can be realized in that from one fastening element 6 the one of a plurality of adjacent fastening elements 6 is selected next and controlled by the nacelle 3, based on the desired one Access route is. Such flexibility could practically not be achieved with conventional guide rails.
  • the guide ropes 7 are only required during the operating phases of the facade elevator and are removed from the facade 5 during the rest of the time.
  • the guide ropes 7 are completely independent of the support ropes 2 of the nacelle 3, which in this example are guided via a rotatable additional boom of the lifting device 1.
  • pivoting movements of the nacelle 3 about a vertical axis can therefore be carried out if necessary despite the threaded guide cables 7.
  • This makes it possible, for example, to move the gondola 3 around a corner of the building facade 5 without having to remove the guide cables 7 beforehand.
  • a system with guide rails would practically not be able to provide a corresponding solution with reasonable effort.
  • the solution according to the invention is characterized in particular by its simplicity and the cost-effective feasibility that it guarantees, in spite of an extraordinary range of possible uses.
