Description

The present invention relates to a device for disassembly and / or assembly of facade or similar cladding elements, in particular asbestos-containing fiber concrete slabs, which are mounted on a building or which are mounted.

From the prior art, a variety of facade, wall or ceiling trim elements are known, which are mounted to form a facade to a building.

As a result of the Thermal Insulation Ordinance, which came into force in 2008, there is a great need for devices and methods with which such facade elements can be removed from the old stock to subsequently equip the structures with heat protection systems, and in particular thermal insulation composite systems, belonging to the state of the art comply with the heat insulation ordinance.

Facades made of fiberboard containing asbestos or the like are a particular problem here. In the years 1937 to 1992, where the asbestos use ban came into force in Germany, approx. 2 billion square meters of asbestos fiber boards were installed throughout Europe, which now has to be disposed of successively.

Asbestos in a naturally occurring mineral, whose mining was banned in Europe in 2005. The dangerous thing about asbestos are the so-called respirable fibers that produce asbestosis and lung cancer. In Germany alone, there are currently 1600 new asbestos diseases per year. Between 1950 and 1980, approximately 150,000 tonnes of asbestos were used in solid and low-strength products in the construction industry. Among the tied products in the construction sector include z. As roofing (corrugated fiberboard) and facade cladding, here are, for example, the well-known Eternit ^® facade panels to call.

Since 1995, legislators have been demanding that only certified experts are allowed to dismantle and dispose of asbestos products in the so-called TRGS519 (Technical Rules for Hazardous Substances).

So far, there are no satisfactory solutions in the prior art for dismantling the above-mentioned facade elements. Usually these are currently disassembled by means of crowbars or screwdrivers, after appropriate safety equipment of the worker. It can not be avoided that many plates break and thus a highly concentrated release of fiber into the air takes place. In particular, in such conventional in the past facade elements that were simply nailed to a substructure or stapled the like, dismantling while avoiding the breakage and a fiber release is a serious problem.

The above problems extend not only to façade elements containing asbestos, but to any façade elements that must be dismantled. Even if, for example, gypsum fiberboards contain no or only minor amounts of hazardous substances, resulting from the known from the prior art dismantling a high dust load, which leads to high follow-up costs especially in the inner cities or makes extensive security measures necessary.

From the JP 2007-239299 A It is known, in the course of dismantling mounted on a structure asbestos-containing fiber concrete slabs by means of serving as a release agent crowbar additionally use a suction that is designed such that it acts on the cladding element with a Absaugunterdruckstrom.

Object of the present invention is to provide a device for disassembly and / or assembly of facade or the like cladding elements, in particular asbestos-containing fiberboard, fiber concrete slabs or the like plates, which are mounted on a building or to be, provide a safe, cost-effective and environmentally friendly Disassembly or assembly allowed.

This object is achieved by a device according to claim 1.

Accordingly, this object is achieved by a device for disassembly and / or assembly of facade or similar cladding elements, in particular asbestos-containing fiber concrete slabs, which are mounted on a building or are mounted, comprising at least one fixing means for releasably securing the device to at least one Facade element, at least one release agent, which is in operative connection with the fixing means for detaching the fixed facade element from the building or for mounting the fixed facade element, and at least one suction means, which is designed such that it acts on the facade element with a Absaugunterdruckstrom.

Fixing means are understood here to mean all means for releasably fixing the device to the facade element and preferably to serve the top of the facade element. These fixative are in operative connection with a release agent, so that applied via the release agent, a force on the fixed facade element and this, possibly after detachment of appropriate fasteners between façade element and structure, can be detached from the building. Under suction means within the scope of this invention means understood, which is also arranged on the device and in particular during the detachment of the fixed facade element this and preferably also its surroundings subjected to a Absaugunterdruckstrom, so that any particles released during detachment are sucked. In principle, the device according to the invention can be used not only for dismantling, but also for mounting the above facade elements. The advantages of the device according to the invention are multilayered:
Thus, as already mentioned, the suction means guarantees an environmentally friendly disassembly of the facade elements, since particles released during detachment, possibly hazardous to health, are sucked out via the suction underflow. For this purpose, the suction means preferably comprises a suction device, for example a vacuum cleaner, which is adapted or adaptable to the respective application of the dismantling device. If, for example, asbestos-containing fiberboard or similar facade panels are removed, the suction means has a suction unit of safety class H (suitable for asbestos materials).

In particular, in the case of façade panels which, as was customary in the past, are fastened, in particular stapled, to a substructure of a structure by means of wire pins or similar pins, the release agent can consist, for example, of one or more peel-off handles which are directly in operative connection with the fixing means. After fixing the device or the fixing means on the respective facade element can then be deducted from the substructure on the executed as a handle release means the respective fixed facade element. Of course, it is also possible here to provide the release agent with a corresponding force-reinforced arm, such as a lift, etc., to ensure the detachment of large plates in particular. It is also conceivable to integrate corresponding solvents for releasing a screw or similar facade element fastening.

A significant advantage is further that a breaking of the plate is prevented by the appropriate design of the fixing. In this respect, therefore, the fixative is so adapted or adaptable in particular in size to the particular application, that guarantees a secure fixing of the facade element and in particular a breaking of the facade element is prevented during detachment.

Further embodiments of the invention will become apparent from the dependent claims.

Preferably, the suction means comprises a suction bell which at least partially encloses the fixed facade element. This suction bell guarantees a safe loading of the facade element with the above suction vacuum flow. Preferably, the suction bell is designed such that it projects beyond the respective facade element with respect to the surface plane laterally. In this respect, the term "enclose" here means a geometry which covers the facade element at least partially in the region of its surface, but preferably also beyond its surface, in the direction of the edge regions.

A preferred embodiment of this suction bell is the production of acrylic glass or a similar translucent plastic, as an optimal view of the fixed facade element is guaranteed. Such plastics are marketed inter alia as Plexiglas ^® in the market.

Preferably, the fixing agent is at least partially disposed in the interior of the suction bell. In this way, therefore, the device can be set on the fixing element on the facade element, while the suction bell at least partially surrounds both the fixer and the facade element and so not only sucks particles when releasing the facade element, which are released laterally and behind the facade element, but also Particles sucked off, which are released when setting the facade element itself. It thus forms a substantially closed hemisphere around the facade element, whereby an optimal suction is guaranteed.

Preferably, the suction bell has a free edge which extends substantially co-planar to a contact plane between the fixed facade element and fixing means. In a substantially planar facade element, the contact plane thus corresponds to the surface level of the facade element. In the fixed state, in such an embodiment, therefore, the free edge of the suction bell is substantially co-planar with the surface plane of the facade element. In an arrangement of several facade elements side by side, as is usually the case with larger facades, so the suction bell can be supported with its free edge on adjacent facade elements, so that an optimal suction in the region of the facade element to be replaced is guaranteed. Of course, it is also conceivable to form the free edge such that it does not stand up directly on the fixed or the adjacent thereto facade elements, but is slightly spaced.

However, it is also conceivable to design the suction bell so that its free edge extends slightly below the contact plane between the fixed facade element and fixing means, ie in a state in which the device is not yet fixed to the facade element, something protrudes beyond the fixing means or its contact surface , In this context, the suction bell is then preferably designed so elastic that is pressed by a pressure on the fixing agent, preferably via the aforementioned release agent, the fixing agent to the facade element and set. In this way, a tension is applied to the suction bell, which guarantees a further enclosure of the detached facade element on detachment on the one hand, and on the other hand facilitates the detachment of the facade element by the resulting from the suction buzzing force. Further relevant embodiments will be discussed in more detail below.

Preferably, the free edge of the suction bell has at least one sealing element. This sealing element serves on the one hand to optimize the suction, on the other hand, but also the damage-free as possible placing the suction bell on the facade element or adjacent facade elements. In this respect, the term "sealing element" here also means a particularly elastic protective element on the free edge of the suction bell.

Preferably, the fixing means has a plurality of fixing heads, which can be fixed on a surface of the facade element. As already mentioned, these fixing heads are designed so that they ensure the most uniform introduction of force when removing the facade element, whereby a breaking of the facade element is prevented. Preferably, these fixing heads are arranged on a base frame, which ensures a uniform grid distribution of the fixing heads on the facade element. In this connection, it is possible to produce in each case a special fixing agent for the façade element sizes customary in the prior art, for example 30 cm × 60 cm. Of course, it is also advantageous to form the fixing means so that it can be adapted to different facade elements via appropriate adapter or sliding elements in its size and orientation. Thus, it may also be possible to provide a plurality of adapter points on an abovementioned base frame for the fixing heads that can be changed in particular in terms of its geometry, to which the fixing heads can be attached if required. Here, all methods and devices known from the prior art for adapting such a base frame or fixing means are applicable, in particular with fixing heads.

In principle, it is possible to adapt the fixing agent to different facade element surfaces. Thus, for example, when disassembling a corrugated fiber element another fixing head find its application, as is the case with the dismantling of flat fiber concrete slabs. For this purpose, preferably corresponding adapter elements are provided to allow the inclusion of different fixing heads.

Preferably, the fixing means and in particular the plurality of fixing heads on a negative pressure means or are in operative connection with such, wherein the fixing means or the plurality of fixing heads via vacuum on the facade element are releasably fixed. The fixing heads are preferably formed here as a vacuum heads, which are used after applying to the surface of the facade element on vacuum firmly on this, so that the facade element is securely fixed.

Basically, corresponding control elements are provided on the device, which enable activation and deactivation of the vacuum means, be it a corresponding vacuum cleaner or corresponding valves on the fixing means. When forming an adaptable fixing means, corresponding blanking plugs or corresponding valves can be used here, which are activated only when a corresponding fixing head or a similar device is used.

Preferably, the suction means and in particular the suction bell on a coupling element for releasably connecting a suction device, as already described above. The coupling element is preferably formed on the suction means and in particular on the suction bell, so that the suction device can be easily connected there, for example by means of a suction hose. Also, an optimal adaptation to the structural conditions is possible in this way, so that, for example, in very high workplaces, a portable suction device or a suction device can be used on the ground with a correspondingly long suction hose.

Preferably, the suction device of the suction means forms a part of the vacuum means. In this respect, therefore, only one device, in particular a vacuum device is necessary, which allows both the suction and the application of the negative pressure to the correspondingly formed fixing. Here, of course, appropriate filters and controls are provided, the latter allow separate activation of the suction and the fixing, for example, to ensure a continuous suction and, if necessary, a vacuum operation for the fixing.

Preferably, the fixing means is movable in particular fixed relative to the suction device and in particular to the suction bell. In this way, for example, the suction bell can be positioned relative to the fixing so that only the fixing means fixed to the surface of the facade element and then the suction bell is movable relative to the fixing in a suction position. It is also possible in this way, for example, in very complex facade elements or facade elements with corresponding recesses to position the fixing so that an optimal introduction of force is ensured, and then the suction or the suction bell to move so that an optimal extraction results. In this context, therefore, the suction means with respect to the fixing means and / or with respect to the fixed facade element can be formed both horizontally and vertically movable.

The determination of the relative mobility between fixing and suction bell can be done by known from the prior art fixing means. It serves, for example, for a first adjustment of the device to on-site conditions or, as will be described in detail below, an optimization of the detachment processes. The fixing means and the suction means or the suction bell are preferably in operative connection with one another via at least one force element, so that, for example, when using the suction bell, at least part of the fixing means is forced into the interior of the suction bell. Thus, the device can be designed, for example, in such a way that, in the non-fixed state, the suction bell and in particular its free edge region project beyond the contact plane of the fixing means, in other words the fixing agent is forced into the interior of the suction bell. When attaching to the facade element so consequently first the suction bell is positioned, started the suction and then pressed the fixing against the force of the force element to fix against the facade element. After fixing the fixed facade element can be pulled over the separation means of the device from its holder on the building, the power element facilitates this detachment by its force and on the other guarantees that simultaneously with the detachment the suction bell (at a corresponding training) laterally Prevents the fixed facade element, whereby an improved suction is guaranteed.

Another advantage of the restraint of the fixative in the interior of the suction bell is also that the device can be stored on site or for example in a building container, with only the free edge of the suction bell is exposed to mechanical influences, while the most sensitive fixative in Push the interior of the suction bell and be protected from damage.

Preferably, the force element has at least one tension spring or similar urging element. This tension spring guarantees a very cost-effective embodiment of the aforementioned device, in which the fixing agent is forced into the interior of the suction bell or in which the fixing agent to the suction bell. Here are all known from the prior art elements for forming an aforementioned "bias" applicable.

Preferably, the force element has at least one vacuum actuator, which can be activated via the vacuum means, or the like actuator. Such an actuator can u. a. operated by negative pressure and in particular by the previously described vacuum means for activating the force elements. Of course, it is also possible to use, for example, electrical actuators that fulfill or support the task of a force element. Correspondingly designed force elements act as part of the abovementioned release agent when detaching the facade elements, since they support, for example, the detachment process by active retraction of the fixed fixing agent into the interior of the suction bell. As soon as the suction bell has been placed on adjacent facade elements and the fixing element has fixed the facade element to be detached, the façade element can be detached or removed from the substructure with little effort by activating the actuator-operated force element, the suction bell acting as a counterforce element.

The tensile force applied to the fixing element by the active force element is preferably introduced into the adjacent facade elements via the suction bell. In this context, it is of course also possible not to arrange the force element or not only between the fixing and the suction bell, but provided accordingly for this purpose Provide counterforce elements that ensure optimal force, caused by the pulling movement of the force elements in the adjacent facade elements. These components can be integrated into the suction bell in the form of reinforcements but also be designed as independent constructions. In particular, in the formation of these drag elements in the form of support structures, which are supported on the adjacent facade elements, it is conceivable to provide appropriate fixing here to ensure a determination of the device on the building even if the detached facade element was subtracted from the building.

Preferably, the suction means and in particular the suction bell on at least one filter element, which is arranged in the suction upstream of the suction device. Such a filter element is preferably a coarse filter element which prevents clogging in particular of the suction device or of the suction hose.

Preferably, the device comprises a control device, which is designed to monitor the operating states of the suction means and / or the fixing means and / or the force element, in particular for monitoring the activation states, the suction power, the prevailing suction or fixing pressures, etc., and a locking device, which is designed such that it only allows activation of the fixing means and / or the force element when the suction means has a predetermined operating state. Such a design thus guarantees, for example, that a detachment of the facade or the elements is only possible if a sufficient suction or even a suction operation is guaranteed. In particular, in the dismantling of facade panels containing hazardous materials, such a "safety device" is advantageous.

Basically, the above-mentioned means are preferably provided with corresponding actuators, in particular switches or the like means to ensure a targeted activation and deactivation of the respective means. Thus, for example, an activation means for the fixing means of the device is preferably arranged on the release agent, so for example a detachment handle of the device, so that a worker hold the device on the detachment handle and trigger the fixing via the actuating means or can cancel. It is also conceivable to provide automatic actuation means which activate and / or deactivate the respective means as a function of detected environmental and / or operating parameters. For example, actuators of the force elements may be designed such that they initiate a detachment movement when a defined suction pressure has been detected at the fixing heads, which suggests a determination of a facade element.

Preferably, the suction bell has access openings which allow access to the Absaugglockeninnenraum and the surface of the fixed facade element, in particular with a tool, so that can be dismantled with the device in a simple way and facade elements, which are defined for example by means of screws on a substructure , The access openings can be exposed here, for example, via predetermined breaking points in the suction bell, so that the suction bell can be adapted to the respectively to be dismantled facade elements. But it is also possible to form lockable access openings that can be opened as needed for the access of a tool. Here it is possible, for example, to provide an access opening with a rubber cover, which allows access with a screwdriver or cordless screwdriver and sealingly abuts a sealing seat on the access opening during the suction operation. In principle, all types of access openings can be formed here, which make it possible to release a facade element fastening from the outside of the suction bell.

In the following, the invention will be described with reference to embodiments, which are explained in more detail by the accompanying drawings. Hereby show:

1 : a schematic representation of a paneled with facade elements structure and an attached embodiment of the disassembly device according to the invention;

2 a plan view of the embodiment of the dismantling device according to 1 ;

3 a cross section through the dismantling device according to 1 ;

4 a cross section through the dismantling device according to 3 with detached facade element;

5 to 7 a stripping operation of a facade element by means of a further embodiment of the dismantling device; and

8th a cross section through a further embodiment of the dismantling device.

In the following, the same reference numbers apply to the same and equivalent components sometimes used to distinguish high indices.

1 shows a schematic representation of a building 3 , here a house, the outside with a plurality of facade elements 2 clad in the form of a facade. The facade elements shown here 2 have a format of, for example, 30 cm × 60 cm and consist of asbestos-containing fiber concrete.

To a reduced risk dismantling this, facade elements 2 to enable finds an embodiment of the device according to the invention 1 their application. The device 1 consists of a fixative 4 comprising attaching at least part of the device to a facade element 2 allowed. The fixative 4 here includes a vacuum means 18 that fixing the fixative by negative pressure on the respective facade element 2 allows. The vacuum means 18 is to a vacuum hose 19 with a vacuum device 17 , For example, connected to an electric or pneumatic vacuum cleaner.

About the fixative so determined 4 can the facade element when attaching a tensile force on appropriately provided release agent 6 from the building 3 be replaced.

Around here the release of particles, be it particles that are behind the facade elements 2 have accumulated or particles that are peeling off the facade element 2 itself arise, to prevent, disposes of the device 1 via a suction device 8th , this is a suction bell 10 having the fixing agents 4 essentially completely surrounds and slightly larger in geometry than the respective facade elements 2 is trained. The suction means 8th or the suction bell 10 are via a suction hose 25 with a suction device 24 , For example, connected to a suitable for the absorption of asbestos fibers sucker or a similar suction device. For the sake of clarity, the vacuum hose 19 and the suction hose 25 as a hose and the vacuum device 17 and the suction device 24 represented as a device. In fact, however, it is possible the fixative 4 or their negative pressure agent 18 so with the suction 8th to combine that both means 8th . 18 over a single hose 19 . 25 and a single suction device or vacuum device 17 . 24 operate. Depending on requirements, of course, two separate systems, ie hoses and suction or vacuum devices find their application.

In the 2 and 3 is an essential part of the device 1 according to 1 in a plan view ( 2 ) and a cross-section (see 3 ). Recognizable is the fixative 4 in this embodiment, a plurality of fixing heads 5 having, via negative pressure to be fixed to the facade element 2 can be pressed.

The fixative 4 has a basic construction 7 made up of several interconnected straps, on which both the fixing heads 5 as well as supply lines 9 the vacuum means 18 are arranged. The fixing heads 5 correspond here known from the prior art Unterdrucksaugnäpfen, in which the supply lines 9 so protrude that in the region of a contact plane E _K (see 3 ) between the fixing heads 5 and the facade element 2 generates a negative pressure and so the fixative 4 on the facade element 2 can be determined.

At the base construction 7 of the fixing agent 4 are two release agents in this embodiment 6 arranged in the form of handles the removal of the fixing agent 4 in particular together with the fixed facade element 2 allow. Instead of the handles 6 Of course, any other type of release means can be used here, as will also be described below.

At the release agents 6 are also activation elements 32 provided in the form of push buttons, the activation / deactivation of the fixing operation, ie the formation of a negative pressure at the respective fixing heads 5 , and allow a suction operation.

To extract particles released during the stripping operation, the device has 1 also on the suction 8th , this is a suction bell 10 comprising, in this embodiment, the fixing agent 4 completely surrounds. In its geometry is this suction bell 10 designed so that it is the facade element to be detached 2 essentially completely encloses the surface side, but rather on adjacent facade elements 2 ' and 2 '' etc. is supported.

The suction bell 10 has a free edge in this embodiment 14 on, on which a sealing element 16 is provided. The free edge 14 or the sealing element 16 are designed such that they are substantially coplanar with the contact plane E _K between the fixing 4 or its fixing heads 5 and the facade element 2 are aligned. In this way, after the setting of the facade element forms 2 by means of the fixing agent 4 a substantially closed interior 12 , out of the above the suction hose 25 Particles can be sucked.

The suction hose 25 is via a coupling element 20 at the suction bell 10 attached, being in this coupling element 20 also a filter element 30 integrated, which serves the coarse filtration of the extracted air. In the area of the suction hose 25 is also the vacuum hose 19 the vacuum means 18 arranged. It can be seen that here both the suction means 8th as well as the fixative 4 or its negative pressure agent 18 via its own suction hose 25 or vacuum hose 19 feature. As already mentioned, however, it is also possible to provide a system in which both the production of the underpressure for fixing and the production of the vacuum for suctioning off a single suction or vacuum device are guaranteed. In this respect, then only a single tube with corresponding valve elements would be necessary to produce the Absaugunterdruck or Fixierunterdruck if necessary.

The suction bell 10 is made of acrylic glass or a similar translucent plastic to allow an optimal view of the work area.

In 4 is the embodiment according to the 1 to 3 again shown in a cross section, now a state with detached facade element 2 is shown. The façade construction shown here consists of façade elements 2 on a substructure 34 on the building 1 (please refer 1 ) by means of steel pins 36 are fixed. By fixing the fixative 4 on the surface 22 of the facade element 2 can over the release agents 6 the facade panel 2 simply pulled out of their fixation and disposed of. Such disposal is usually carried out in so-called big bags, in which the particular asbestos-containing facade elements 2 stored and sealed a further disposal.

It is clear in the embodiment shown here that the suction bell 10 the facade element covered in the detached state, so that in the interior 12 prevailing negative pressure leads to a suction flow, the side of the facade element 2 flows past, so that there are free particles also sucked.

The 5 to 7 show a disassembly process of a facade element 2 using a further embodiment of the disassembly device according to the invention 1 ,

This embodiment again has a fixing agent 4 fixing the device on the surface 22 of the facade element 2 on, the determination here also via a vacuum means 18 he follows. Also provided is the suction means 8th or its suction bell 10 in whose interior 12 the fixative 4 is arranged.

In contrast to the embodiment above, here are the fixing agent and the suction means 8th or its suction bell 10 movable relative to each other, wherein between the suction bell 10 and the fixative 4 a plurality of force elements 26 are arranged. These relative movements are in the 6 and 7 represented by corresponding movement arrows representing the movement of the fixative 4 relative to the suction bell 10 symbolize during the detachment process.

The device 1 is formed in this embodiment so that a relative movement between fixing 4 and suction bell 8th essentially orthogonal to the surface 22 of the facade element 2 is possible. The force elements 26 have tension springs 28 in such a way that (see 5 ) the fixing agent 4 in the interior 12 the suction bell 10 is urged.

Within the scope of the present application, this definition is understood to mean, in particular, the contact plane E _{K of} the fixing heads 5 of the fixing agent 4 from the free edge 14 the suction bell 10 in the direction of the interior 12 is urged. In doing so, the in 5 illustrated alignment between fixative 4 and suction bell 10 a rest position in which the suction bell 10 unproblematic relative to the facade element to be detached 2 can be aligned. In addition, in this position, the most sensitive fixing heads 5 against mechanical loads through the suction bell 10 protected.

As in 6 can be shown by pressure on the release agent 6 the fixative 4 against the force of the force elements 26 on the facade element 2 to be moved and there, here after activation of the negative pressure, are set. In this state, therefore, the suction bell 10 in the direction of the facade element 2 biased.

This bias is released as soon as the facade element 2 from the substructure shown here 34 detached and the fixed facade element 2 is deducted (see 6 ). The force elements 26 then urge the fixative 4 back in the already in 5 shown rest position, namely in the interior 12 the suction bell 10 , Due to the corresponding geometry of the suction bell 10 while sliding the free edge 14 on the detached facade element 2 over in the direction of the substructure 34 , so that also facade element underside 23 a particle extraction takes place.

Depending on the design of the force elements 26 can be in this way, the detachment process (see 6 and 7 ) support. So it is possible, for example, the tension springs shown here 28 such that they facilitate the detachment process. As in 6 recognizable, is the by the stretched force element 26 or the stretched tension spring 28 resulting tensile force on the suction bell 10 in the neighboring facade elements 2 ' respectively. 2 '' derived. When removing the facade element 2 supports this biasing force so the detachment process. To here a sufficient stability of the suction bell 10 To ensure, it is of course possible to train them with corresponding counterforce elements or provide independent counterforce elements on the device with the force elements 26 or the fixative 4 are in operative connection, so that a power dissipation in the adjacent facade elements 2 ' . 2 '' primarily about such elements and not or only partially about the suction bell 10 even done.

In a preferred embodiment, it is also possible, the force elements 26 be provided with electrically, hydraulically but preferably by negative pressure activatable actuators, the in 7 Support shown Rückdrängvorgang. With a corresponding design of the suction bell 10 or previously mentioned counterforce elements can thus via these actuators in the force elements 26 in a very simple way the facade element 2 from the substructure 34 be replaced. In this context, it is of course possible, the force elements 26 to be provided with a combination of compression springs and actuators, wherein z. B. the compression springs the fixative 4 from the interior 12 push out and then retract the activated actuators to the facade element 2 replace.

8th shows a further embodiment of the device according to the invention also in cross section. It is obvious here that at the suction bell 10 a plurality of access openings 38 are provided, which gives access to the interior 12 the suction bell 10 enable. About this access opening, for example, a screwdriver or cordless screwdriver can be supplied, for example, such facade elements 2 not, as previously shown, by means of steel pins on the substructure 34 are fixed, but screwed or the like were attached. To ensure a safe suction is the access opening 38 by means of a particular elastic sealing element 40 locked. Of course, other known from the prior art configurations of corresponding access openings and seals for such can be used here. In particular, it is possible to have a plurality of different access openings 38 especially at different positions of the suction bell 10 which can be opened and closed as needed. In addition to the previously shown sealing elements 40 Of course, other closure devices can find their application here, in particular screw cap or break-off covers.
