(17) FIG. 10 a horizontal section of the further embodiment of the wall element in accordance with the invention in the installed state.

(18) In accordance with the illustration in FIGS. 1 to 3 a dry partition wall system 1 comprises a plurality of wall elements 2, a floor-side connection element 3, a ceiling-side connection element 4, and a wall-side connection element 5. In the illustrated embodiment two wall elements 2 are arranged side by side. Their number varies, however, in the end as a function of the length of the partition wall to be made. The dry partition wall system 1 is arranged in an installation space between a floor B, a wall W, and a ceiling D. Both the floor-side connection element 3 and the ceiling-side connection element 4 extend over several wall elements 2 and serve for orientation of the wall elements 2.

(19) Each wall element 2 comprises an insulation layer 21 formed of mineral wool as well as a complete planking 22 on one side and a divided planking 23 on the other side. The wall element 2 is thus of multi-layer construction comprising an insulation core and plankings at the outer sides.

(20) FIG. 3 shows details of the wall connection of the wall element 2 and/or the connections between the wall elements 2. The wall element 2 is pushed on the wall-side connection element 5 such that the connection element 5 comes to lie between the plankings 22 and 23. The space in the region of the wall-side connection element 5 is also filled with an insulation. The wall element 2 is then fastened thereto by means of drywall screws.

(21) In accordance with the illustration in FIG. 4 the divided planking 23 is composed of a main planking 23a and a connection strip 23b. The connection strip 23b is first of all omitted during the installation of the wall element 2 and is finally applied to the wall element 2 for producing a form fit with the floor-side connection element 3. The mode of fastening of the connection strip 23b will be explained in detail later.

(22) The wall element 2 comprises further a lower load-bearing element 24 which is displaceable and hence positionable between the plankings 22 and 23. The load-bearing element 24 has a substantially X-shaped cross-section and will be explained in detail later.

(23) As is shown especially in FIG. 5, the wall profile 2 further comprises an outer upright edge profile 26 at one side edge face and an inner upright edge profile 27 at the other side edge face. These are of C-shaped design and formed of a metal profile with a profile width of 75 mm. The profiles 26 and 27 provide a stable framework for the wall element 2 and connect the respective plankings 22 and 23. The load bearing element 24 is further inserted in the edge profile 26 in the floor region.

(24) The plankings 22 and 23 are formed of plasterboards, preferably in the kind of plaster fiberboards. They are in a per se conventional manner fixed to the profiles 26 and 27 by means of drywall screws.

(25) As may additionally be taken from the horizontal section illustrated in FIG. 5, the insulation layer 21 protrudes with the outer upright edge profile 26 laterally over the plankings 22 and 23. In the other edge section the insulation layer 21, however, recedes with the inner upright edge profile 27 relative to the plankings 22 and 23 and forms a groove therewith. The wall elements 2 thus each have a protrusion and a groove at their upright longitudinal edges, so that they may be coupled reliably with adjacent wall elements in the kind of a tongue and groove joint. This produces a form-fit connection which may be secured additionally by drywall screws.

(26) The floor-side connection element 3 is designed substantially U-shaped of a metal profile. In the instant embodiment it comprises the illustrated stepped U-shape pursuant to FIGS. 3 and 4. It may then be embedded reliably in a screed. Moreover, in the illustrated embodiment it comprises two legs of different length, the longer of them serving as an end-stop for the complete planking.

(27) The wall-side connection element 5 is also U-shaped. The ceiling-side connection element 4 is also designed as a U-profile in this embodiment.

(28) FIG. 3 shows the ceiling connection of the wall element 2. As may be taken therefrom, the two plankings 22 and 23 encompass the ceiling-side connection element 4 on both sides and thus produce a form fit. The wall element 2 moreover abuts on the ceiling D. The connection of the wall element 2 with the connection element 4 and/or the ceiling D is thus gap-free.

(29) As may be seen from FIG. 4, the floor-side connection element 3 encompasses the load-bearing element 24 of the wall element 2 also in a form-fit manner. At the same time the floor-side connection element 3 serves, at the outer side at its longer leg, as an end-stop for the complete planking 22 while it is, at the other side, in engagement with a locking retainer 28 holding the connection strip 23b.

(30) The locking retainer 28 is illustrated in more detail in FIGS. 6a, 6b, and 6c. As soon as the wall element 2 is in its intended position, the multi-part planking 23 may be completed by the connection strip 23b. The locking retainer 28 is firmly connected with the connection strip 23b. This arrangement is then inserted in the free space between the main planking 23a, the divided planking 23, and the floor-side connection element 3 such that a long leg of the locking retainer 28 comes to lie behind the main planking 3a within the wall element 2. It exerts an elastic force keeping it reliably in place. At the same time, a chamfer of the locking retainer 28 is inserted behind the shorter leg of the connection element 3 in that the locking retainer 28 is displaced downward. The connection strip 23b is then externally in abutment with the main planking 23a and produces a spatial termination. The locking connection enables advantageously a non-destructive removal of the connection strip 23b if necessary.

(31) An insulation of mineral wool is further arranged in the cavity of the floor-side connection element 3.

(32) FIGS. 7a to 7c show a load-bearing element 24 pursuant to a first embodiment. FIG. 7a illustrates a front view of the load-bearing element which reveals the X-shaped basic design with a profile closed in the upper half. A side view is illustrated in FIG. 7b. FIG. 7c illustrates by means of a schematic plan view of the load-bearing element 24 how it is positioned in an upright edge profile 26 (or 27). It is caught therein circumferentially, but may be displaced and/or pulled out in the longitudinal direction of the edge profile. The elements may then be fixed to one another by screws, rivets, or the like.

(33) FIGS. 8a to 8c show a somewhat modified design of a load-bearing element 24′. It has, matching an edge profile 26′, a smaller dimension in a main direction, but is irrespective thereof of functionally identical design to the load-bearing element 24 of FIGS. 7a to 7c.

(34) The installation process of the dry partition wall system 1 will be explained in the following:

(35) First of all the installation space for the dry partition wall system 1 is prepared. For this purpose, the floor-side connection element 3, the ceiling-side connection element, and the wall-side connection element 5 are installed on the floor B, the wall W, and the ceiling D. They are dowelled in the usual manner.

(36) At the same time, a plurality of wall elements 2 may be preassembled in the factory and finally be provided at the building site. In this case the connection strip 23b of the divided planking 23 is first omitted.

(37) In the following the steps for erecting the wall element will be illustrated. A first wall element 2 is applied in the inclined state on the ceiling-side connection element 4 and is finally pivoted there about until it is in the upright position. This step may be performed manually or with the aid of a suitable transport and positioning device such as a vacuum lifting device. The complete planking 22 gets into abutment with one side of the floor-side connection element 3. The plankings 22 and 23 of the wall element 2 encompass in this state the ceiling-side connection element 4 on the outer side with positive locking.

(38) The wall element 2 is in this state in sliding connection with the floor-side connection element 3 and the ceiling-side connection element 4 and is displaced thereon in the direction of the wall-side connection element 5. There, it gets into engagement therewith in the manner illustrated in FIG. 2.

(39) In a next step the wall element 2 is raised until it is in abutment with the ceiling D. A connection seal in the form of two sealing tapes 29 arranged between the ceiling-side connection element 4 and the ceiling D seals the space between these two elements. In this embodiment the sealing tapes 29 are designed as a compressible sealing tape and are fastened to the ceiling-side connection element 4 by means of gluing.

(40) As soon as the positioning of the wall element 2 has been finished, the load-bearing element 24 is pulled out from the edge profile 26 until it supports the wall element 2 on the floor side. The X-shaped cross-section of the load-bearing elements 24 supports the pulling out thereof from the edge profile, on the one hand, and additionally stabilizes the arrangement, on the other hand. Then, the load-bearing element 24 is fixed by means of drywall screws or the like at the section of the edge profile 26 which is free at that moment. The wall element is thus retained reliably in place. Likewise, the ceiling-side connection element 4 and the wall-side connection element 5 are connected with the plankings 23 and 23 by means of drywall screws or the like.

(41) Subsequently, a further wall element 2 is provided, applied to the ceiling-side connection element 4, and taken from the inclined position to the upright position. This wall element 2, too, is then displaced laterally in the direction of the wall element 2 that has already been installed, until it engages therein with positive locking in the manner illustrated in FIG. 3. Then, raising of the wall element 2 along with pulling out of the load-bearing elements 24 and fixing thereof takes place as described before, and fixing of the wall element at the ceiling-side connection element 4 and at the upright edge profile 26 of the other wall element 2 by means of drywall screws or the like.

(42) This process is repeated until all wall elements 2 necessary for forming the dry partition wall system 1 have been installed. If a clearance to a further side wall remains at the edge, the missing wall piece may be manufactured manually in the usual manner if necessary.

(43) Finally, the connection strip 23b is then applied to the main planking 23a and/or the wall element 2 and is fastened by means of the locking retainer 28 and possibly by drywall screws.

(44) Then, the dry partition wall system 1 as such is finished.

(45) In a concretely tested embodiment the dimension of an individual wall element was 2600×600×100 mm, wherein the edge profiles 26 and 27 had a width of 75 mm and the plankings had a thickness of 12.5 mm. The insulation material used was glass wool 60 mm with a bulk density of 16 kg/m.sup.3. The area-related weight of the dry partition wall system was approx. 41.8 kg/m.sup.2.

(46) The visible surface of the plankings 22 and 23 is finally filled, ground, and provided with a top layer by painting or a wallpaper, etc. in the usual manner. Moreover, the plankings 22 and 23 may also have been provided with a bonding agent, a moisture protection, or the like in the factory. For the handling with a vacuum lifting device a coating may also be applied on at least one planking, said coating enabling the reliable maintaining of the vacuum and hence handling during installation.

(47) In the region of the floor B a screed is applied as a rule, which is decoupled from the partition wall by means of an edge insulation strip.

(48) In addition to the embodiments explained the invention allows for further design approaches.

(49) In accordance with the illustration in FIGS. 9 and 10, wall elements 2′ may also be designed such that the plankings 22 and 23 are laterally staggered from one another. At the connection places with the lateral wall W appropriate fitting parts may then possibly be provided for producing a complete termination.

(50) If the connection situation especially in the floor region is solved in a different manner, the providing of a divided planking 23 may be omitted. This is, for instance, possible if the planking does not produce form fitting with the floor-side connection element 3 on one side.

(51) For optical or other reasons the wall element may also be applied to the ceiling in a non-abutting manner for the purpose of creating a joint.

(52) The connection strip 23b may also be designed such that it is flush with the main planking 23a in the installed state. The locking retainer 28 is then correspondingly modified, or a different kind of fastening of the connection strip 23b to the wall element 2 is chosen.

(53) The lateral wall connection of the wall element 2 to the wall-side connection element 5 may be made in different ways. On the one hand, an insulation strip may be arranged in the connection element 5 in advance, said insulation strip filling the groove of the wall element 2 which is provided by the plankings 22 and 23 in cooperation with the recessed insulation layer 21, and thus avoids a gap in this place. A further possibility consists in providing the wall element in this place as a special component without a groove by a recessed insulation layer 21.

(54) In particular application cases the sealing tapes 29 of the connection seal may also be renounced. This is especially the case when the sound insulation effect is of minor importance.

(55) On the other hand, the connection seal may also be formed of another suitable sealing material. Basically any conventional sealing material, such as cellular rubber or the like is suited to produce the desired absence of gap. Compressible sealing bands come also into consideration. Furthermore, the cavity may be foamed.

(56) Furthermore, it is not necessary that the plankings 22 and 23 are connected with each other via C profiles over the height of the wall element 2. Instead, U profiles or square tubes, or the like may also be used.

(57) If the lateral wall connection of the wall element 2 can also be made in a suitable manner in a different way, it is also possible to renounce the wall-side connection element 5.

(58) In general, it is not required, either, that metal profiles are used as a support framework of the wall elements. Basically, also components of wood, plastics, or the like may be used.

(59) The providing of a tongue and groove joint at the side edges of the wall elements 2 is not necessary, either. In some application cases it is sufficient if the wall elements 2 are placed side by side and the joints are then filled. A design of this kind especially would have the advantage that no lateral displacement of the wall elements is required in the course of installation.

(60) This applies equally for the fact that the wall elements would have to be screwed with one another at their side edges. This indeed increases the stability of the partition wall and avoids reliably cracks at the seams, but it may also be omitted if sufficient stability of the partition wall is also achieved without this measure.

(61) The stepped U-shape of the floor-side connection element 3 according to the illustration in FIGS. 3 and 4 is by no means necessary. The embedding in the floor may consequently be renounced. Instead, the floor-side connection element 3 may have a conventional U-profile design and simply be placed on the floor B and be fastened there.

(62) The floor-side connection element 3 and the wall-side connection element 5 need not be formed as a U-shaped profile, on the other hand. A C-shaped profile or the like may also be used. Moreover, no metal has to be used, but it may be sufficient to use wood, plastics, or the like where applicable. The arranging of an insulation filler in the floor-side connection element 3 and in the wall-side connection element 5 may furthermore also be renounced.

(63) It is not necessary that the plankings 22 and 23 consist of one layer of plasterboard or plaster fiberboard. In another embodiment also two or more layers of plasterboard or plaster fiberboard may be provided.

(64) Moreover, the plankings 22 and 23 need not be provided of plasterboard or of plaster fiber board, but may also consist of wood fiberboards, mineral fiberboards, or the like.

(65) For the insulation layer 21 in the wall element 2 an insulation material differing from mineral wool may also be used, for instance, of an organic material such as wood soft fiber, reed, or Typha. Foamed plastics of polyethylene, polystyrene, polyurethane, or the like have proved of value in practice due to their good insulation effect. In the case of minor requirements to sound insulation the insulation layer 21 may also be omitted.

(66) In the wall elements 2 empty tubes may also be available, or lines may be laid in the course of installation so as to provide electric power supply and/or data cables, etc. in particular positions in the room.
