Description

This Invention a device for dismantling facade or the like Cladding elements, in particular asbestos-containing fiber concrete slabs, the on a building are mounted.

Out because state of the art are a variety of facade, wall or Ceiling trim elements known to form a facade on a building are mounted.

When Result of the came into force in 2008 thermal insulation regulation exists a high demand for devices and methods with which such Facade elements from the old stock can be removed to then the buildings with in the meantime belonging to the state of the art heat protection systems and in particular Thermal insulation composite systems equip, to the requirements of the Heat Insulation Ordinance enough afford to.

One façades made of fiberboards containing asbestos pose a particular problem here or similar material. Thus, in the years 1937 to 1992, the ban on asbestos use in Germany came into force Approx. 2 billion square meters of asbestos fiber boards installed throughout Europe, which now has to be disposed of successively.

asbestos in a course occurring mineral, whose mining in 2005 banned Europe-wide has been. The dangerous one Asbestos contains the so - called respirable fibers, which are asbestosis and Produce lung cancer. There are 1600 in Germany alone new asbestos diseases per year. Between the years 1950 to 1980 were about

150000 Tons of asbestos in solid and low-strength products in the construction industry. Among the tied products in the construction sector include z. B. Roofing (corrugated fiberboard) and facade cladding, here For example, the well-known Eternit facade panels can be mentioned.

since In 1995, the legislator demands that only certified experts dismantle and may dispose of asbestos products in the so-called TRGS519 (Technical rules for hazardous substances).

So far exist in the prior art, no satisfactory solutions for Disassembly of above-mentioned facade elements. Usually, these are currently, according to appropriate safety equipment of the worker, by means of crowbars or screwdrivers dismantled. It is unavoidable that many plates break and thus a highly concentrated fiber release into the air. Especially with such in the past usual Façade elements that simply nailed to a substructure or the like, the dismantling at the same time Prevention of breakage and fiber release a serious Problem.

Above Problems do not only extend to façade elements containing asbestos, but on any façade elements that must be dismantled. Also if, for example, gypsum fiberboards no or only minor amounts at health-endangering Contain substances results from those of the prior art known dismantling a high dust load, especially in the inner cities leads to high follow-up costs or extensive security measures necessary.

task The present invention accordingly provides a device for Disassembly of façade or similar cladding elements, in particular asbestos fiberboards, fiber concrete slabs or to offer the like panels mounted on a structure, the one safe, cost effective and environmentally friendly dismantling allowed.

These The object is achieved by a device according to claim 1.

Especially 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 are, solved, comprising at least one fixing means for releasably securing the device on at least one facade element, at least one release agent, which is in operative connection with the fixing agent for detachment of the specified Facade element of the building, and at least one suction means, which is designed such that it subjected the facade element with a Absaugunterdruckstrom.

Fixing means are understood here to mean all means which serve for the releasable fixing of the device on the facade element and preferably on the upper side of the facade element. These fixatives 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, be detached from the building. By suction means is understood in the scope of this invention, a means 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 off. In principle, the device according to the invention can be used not only for disassembly, 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).

Especially for façade panels, as usual in the past Wire pins or the like pins on a substructure attached to a building In particular, the release agent may be off, for example one or more Abziehgriffe exist directly with the fixing in operative connection. After setting the device or the Fixing agent on the respective facade element can then on the executed as a handle release agent the respective fixed facade element simply from the substructure subtracted from. Naturally But it is also possible here release agent with a corresponding force-reinforced arm, for example one hydraulic ramp etc. to provide the peeling especially of large ones Ensure plates. It is also conceivable corresponding solvents to release to integrate a screw or the like Fassadenelementbefestigung.

One Another significant advantage is that through the appropriate training the fixer prevents the plate from breaking. insofar So is the fixative such, especially in size to the each application adapted or adaptable that a secure fixing of the facade element guaranteed and in particular a breakage of the facade element is prevented during detachment.

Preferably the suction means comprises a suction bell, the fixed Façade element at least partially encloses. This suction bell guarantees a safe admission of the facade element with the above Absaugunterdruckstrom. Preferably, the suction bell is such designed to be in relation to the respective facade element its surface level surmounted laterally. In this respect, the term "enclose" here means a geometry the facade element at least partially in the region of its surface, preferably but also about its surface also covered in the direction of the edge areas.

A preferred embodiment of this suction bell is the preparation of Acrylic glass or a similar translucent plastic, since so ensures an optimal view of the fixed facade element remains. On the market such plastics u. a. as Plexiglas expelled

Preferably the fixing agent is at least partially in the interior of the suction bell arranged. In this way, so the device on the Fixing agents are fixed to the facade element while the Suction cup both the fixer and the facade element at least partially encloses and so when peeling the facade element not only sucks particles, the side and be released behind the facade element, but also particles sucks, which are released when setting the facade element itself. So it forms a substantially closed hemisphere around the Façade element, which ensures optimum extraction performance.

Preferably the suction bell has a free edge, essentially Co-planar to a contact plane between fixed facade element and fixative runs. For a substantially planar facade element corresponds to the contact plane hence the surface plane of the facade element. In the fixed state closes at a such embodiment So the free edge of the suction bell is essentially co-planar with the surface level of the facade element. In an arrangement of several facade elements next to each other, as is the case with larger facades the case is, so can the suction bell with its free edge supported on adjacent facade elements, so that an optimal Ensures extraction in the region of the facade element to be replaced is. Naturally However, it is also conceivable to form the free edge in such a way that he does not directly on the specified or the adjacent thereto Façade elements stands up, but is slightly spaced.

However, it is also conceivable to design the suction bell in such a way that its free edge extends slightly below the contact plane between the fixed facade element and the fixing means, ie in egg NEM state in which the device is not yet fixed to the facade element something about the fixing means or its contact surface protrudes. 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 on. This sealing element serves on the one hand to optimize the suction power, on the other hand as well as possible damage-free Placing the suction bell on the facade element or adjacent Facade elements. In this respect, the term "sealing element" is also here a particular elastic protective element on the free edge of the suction bell to understand.

Preferably the fixing means comprises a plurality of fixing heads arranged on a surface of the Facade element can be fixed. As already mentioned, these are Fixierköpfe in this case designed so that they give a uniform as possible force application when peeling off of the façade element, whereby a breakage of the facade element is prevented. Preferably these fixing heads arranged on a base frame, which has a uniform grid distribution of Fixing heads over the Facade element ensures. In this context, it is possible for the off conventional in the art Façade element sizes, for example 30 cm × 60 cm, each to produce a special fixative. Of course it is but also advantageous to form the fixer so that it has appropriate Adapter or sliding elements in size and orientation to different Facade elements is customizable. That's the way it can be possible on an above-mentioned in particular in its geometry changeable Basic frame for the fixing heads provide several adapter points, attached to the fixing heads if necessary can be. Here are all out the prior art methods and devices for adaptation such a base frame or fixing in particular with Fixierköpfen applicable.

Basically it is possible to adapt the fixing agent to different facade element surfaces. For example, when disassembling a corrugated fiber element another fixation head find its application than this in the Disassembly of flat Fasbeetonplatten is the case. These are preferably corresponding adapter elements provided to accommodate different Fixierköpfe to allow.

Preferably have the fixing agent and in particular the plurality of fixing heads Vacuum means on or are in operative connection with such, wherein the fixing means or the plurality of fixing heads via negative pressure detachable on the facade element are definable. The fixing heads are Here preferably designed as a vacuum heads, which after the Apply to the surface of the facade element over Vacuum firmly be used on this, so that the facade element is securely set.

Basically provided on the device corresponding controls that an activation and deactivation of the vacuum means, be it So a corresponding vacuum cleaner or equivalent Allow valves on the fixative. In the formation of an adaptable fixative can here corresponding blind seals or appropriate valves find their application, which only then activated when a corresponding fixing head or the like Device is used.

Preferably has the suction means and in particular the suction bell a coupling element on to the detachable Connection of a suction device, as previously described has been. The coupling element is preferably on the suction means and in particular formed on the suction bell, so that the suction device There, for example, simply connected by means of a suction hose can be. Also in this way is an optimal adaptation the structural conditions possible, so that, for example, at very high altitude jobs transportable suction device or a suction device on the ground can be used with a correspondingly long suction hose.

Preferably the suction device of the suction means forms part of the vacuum means. insofar So is only a device, in particular a vacuum device necessary, both the suction and the application of negative pressure allowed on the appropriately trained fixative. Here are Naturally provide appropriate filters and controls, with the second one separate activation of the suction device and the fixing agent enable, for example, a continuous suction and if needed a Low pressure operation for ensure the fixative.

Preferably is the fixing means relative to the suction device and in particular to the suction bell in particular fixed movable. In this way For example, the suction bell relative to the fixing so be positioned so that only the fixing agent on the surface of the Set facade element and then the suction bell relative for fixing to a suction position is movable. Also is it in this way possible, For example, in very complex facade elements or facade elements with corresponding recesses to position the fixative so that an optimal introduction of force is ensured, and then the To move suction or the suction bell so that an optimal Suction power results. In this context, so that can Absaugmittel respect of the fixing agent and / or with respect the fixed facade element both horizontally and vertically be formed movable.

The Determining the relative mobility between fixative and suction bell can be done by known from the prior art fixing means. It serves, for example, for initial adjustment of the device On-site conditions or, as detailed below will be described, an optimization of the detachment processes.

Preferably are the fixing and the suction or the suction bell over at least a force element in operative connection with each other, so that, for example at least part of the fixing agent when using the suction bell is forced into the interior of the suction bell. So can the device In this case, for example, be designed so that in the unspecified Condition, the suction bell and in particular their free edge area on the Contact plane of the fixative protrude, in other words So the fixative is forced into the interior of the suction bell. When attaching to the facade element so consequently first Suction cup positioned, the suction operation started and then the fixing against the force of the force element laying down pressed against the facade element. To the fixation, the fixed facade element on the release agent the device to be pulled from its holder on the building, wherein the Force element on the one hand this detachment by its force and, secondly, guarantees that at the same time as the supersede the suction bell (with a corresponding training) laterally on the fixed facade element vorbeidrängt, creating an improved Suction power is guaranteed.

One Another advantage of restraining the fixative in the interior of the suction bell is also that the device so stored on the site or for example in a construction container can be, with only the free edge of the suction bell mechanical influences is suspended while the most sensitive fixative in the interior of the suction bell press and so from damage protected become.

Preferably For example, the force element has at least one tension spring or the like urging on. This tension spring guarantees a very cost-effective design of the aforementioned device, in which the fixing agent in the interior of the suction bell or in which the fixing agent is forced onto the suction bell. Here are all out The prior art known elements for forming an aforementioned "bias" applicable.

Preferably the force element has at least one vacuum actuator, which via the Vacuum means is activated, or the like actuator on. One such actor can u. a. by negative pressure and in particular by the previously described negative pressure means for activating the Power elements are operated. Of course it is also possible, for example to use electrical actuators, the task of a force element fulfill or support. Appropriately trained force elements act on detachment of the Façade elements as part of the aforementioned release agent, since they, for example the detachment process by active withdrawal of the fixed fixing agent in the interior of the suction bell support. Once the suction bell mounted on adjacent facade elements and the fixing agent to be detached Facade element has set, can be activated by the activation of the actuator Kraftelementes the facade element with little effort of detached the substructure or deducted, wherein the suction bell as a counterforce element acts.

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 not possible to arrange the force element or not only between the fixing and the suction bell, but provided correspondingly provided for this purpose counter force elements, which 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 also here before appropriate fixing watch to ensure a determination of the device on the building even if the detached facade element was removed from the building.

Preferably has the suction means and in particular the suction bell at least a filter element in the suction before the suction is arranged. Such a filter element is preferably a coarse filter element, the clogging particular of the suction or the suction hose prevented.

Preferably the device comprises a control device for monitoring the operating conditions the suction means and / or the fixing means and / or the force element, especially for monitoring the activation states, the Suction power, the prevailing suction or fixation pressures, etc. is formed, and a locking device, which is formed is that it is an activation of the fixative and / or the force element only allowed if the suction means a specified operating condition having. Such an education guarantees, for example, that a detachment the facade or the elements is only possible, if sufficient Absaugleistung or at all a suction operation is guaranteed. Especially during disassembly of façade panels containing harmful substances Such a "safety device" advantageous.

Basically above-mentioned means, preferably with corresponding actuating elements, In particular, switches or the like means provided to a to ensure targeted activation and deactivation of the respective funds. Thus, for example, an activating agent for the fixing of the device preferably on the release agent, So for example, a detachment handle arranged the device, so that a worker the device at the detaching handle hold and over the actuating means trigger the fixing process or can cancel. It is also conceivable automatic actuating means to provide, depending on detected ambient and / or operating parameters the respective Activate and / or deactivate funds. For example, actuators the force elements be designed such that they have a detachment movement initiate when a set suction pressure is detected at the fixation heads which suggests a fixing of a façade element.

Preferably the suction bell has access openings on, in particular, if necessary, access to Absaugglockeninnenraum and to the surface the fixed facade element in particular with a tool enable, so that with the device in a simple way also facade elements can be dismantled, for example, by means of screws on a substructure are fixed. The access openings can here for example about Predetermined breaking points in the suction bell be exposed, so that the Suction bell to the respectively to be dismantled facade elements adaptable is. But it is also possible, lockable access openings Train as needed for access of a tool open can be. Here it is possible, for example, an access opening To provide with a rubber cover, the access with a screwdriver or cordless screwdriver and sealing in a suction at a Sealing seat at the access opening is applied. in principle are all here Types of access openings can be formed, which can be solved a Fassadenelementbefestigung from the outside of the suction bell enable.

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

in the The invention will be described below with reference to exemplary 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 The following will be for same and equivalent components used the same reference numerals, sometimes high indices are used for differentiation.

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 dargestell here ten façade elements 2 have a format of, for example, 30 cm × 60 cm and consist of asbestos-containing fiber concrete.

To a reduced risk dismantling of these 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, it is possible the fixatives 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 formed such that they are substantially co-planar 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 negative pressure tube 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 Ventilele would be required to produce if necessary, the Absaugunterdruck or Fixierunterdruck.

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 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 provide sufficient stability the suction bell 10 ensure, it is of course possible to form these elements with corresponding counterforce or provide independent counter force 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 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.
