Description

The invention relates to a wall element arrangement, in particular for the interior construction of buildings, with at least one wall element, which consists of a support frame constructed from, in particular of metal, suitably steel or plastic, U or C profiles and cover plates fastened thereon, preferably is made of plasterboard, as well as a filling of heat and / or sound-insulating material arranged between them, expediently made of mineral wool, and with at least one bracing device on at least one supporting frame edge to compensate for differences in the dimensions of the wall element and the part of the building that accommodates it, at least a part of the support frame can be set back or set back with respect to at least one edge of at least one of the cover plates.

The aim of the invention is to create a wall element arrangement that uses largely wall elements manufactured in the factory and which, in a particularly favorable manner, allows the adaptation to the spatial dimensions of buildings up to a predetermined size without or without major assembly processes for walls on the construction site offers. This is primarily intended to achieve a dry erection of partitions in the interior of buildings with the least specialist knowledge and with the least tool and fixture expenditure. In addition, the most disruptive facings should be eliminated.

Industrially prefabricated wall elements, consisting of a frame construction and cover plates fastened to it on both sides, have already found widespread use as part of the prefabricated construction. Some of these wall elements are produced in predetermined grid dimensions; however, they are usually designed in terms of thickness and dimensions for a specific type of prefabricated house for which they can only be used. The advantage of such wall elements is on the one hand in an industrial assembly line production and therefore in a cost saving. However, this cost saving is limited in the known wall elements in that, due to the use only for certain prefabricated house types, the number of pieces also necessarily remains limited and the possible rationalization advantages of assembly line production can therefore only be used to a limited extent.

On the other hand, wall designs have become known in which a wall can be produced by constructions to be created by the customer, wherein here it is also possible to individually adapt to existing building dimensions or different house types. The advantage of individual adaptability on the one hand, however, is in turn paid for with the loss of rationalization options, since here no finished wall elements but adaptable kit constructions are used on site.

The object of the invention is, on the one hand, to use largely prefabricated components that can be adapted to varying building dimensions, and, on the other hand, to facilitate the assembly of such prefabricated components. In addition, electrical, plumbing and gas installations are to be made easier.

This is achieved in a wall element arrangement of the type specified at the outset that, in order to hold the wall elements on the part of the building, in particular on ceilings, and, if appropriate, for connecting adjacent wall elements, at least one that extends or can only be inserted into the space between the cover plates from a known U. - or C-profile with existing in the above-mentioned space or insertable in this and also at least at the ends, advantageously up to about half the height of the leg, bent towards the profile center, with the profile center plane including an acute angle profile leg existing bearing part is provided , The web of this U or C profile has fastening devices, advantageously slots, for the purpose of anchoring this bearing part and thus the wall element on the building part, in particular the ceiling, and that the support frame in the edge area facing the bearing part consists of a separate part from the aforementioned bearing part, only inside the cover plates arranged U- or C-profile, which is open to the bearing part and whose legs are at a greater distance from each other than the distance of the outer surfaces of the legs of the bearing part, and that the support frame in wall element sides or areas remote from the bearing part , expediently in the wall element area remote from the bearing part, in particular on the bottom side of the wall element, has only U or C profiles arranged inside the cover plates with an external web and thus an inwardly open profile.

The bevels of the bearing parts thus provided in connection with the profiles of the support frame which are open to them not only facilitate the installation and secure storage of the wall elements, in particular on the ceiling, but also the accommodation of pipes for the installations.

A training which has become known through GB-PS 1 384 587, in particular its FIG. 3, shows a profile for fastening wall elements to the ceiling. However, this profile not only has flanges reaching into the space between the cover plates, but also those on the outside of the cover plate, so that the installation of the wall elements is considerably more difficult, despite bending the lower ends of the inner legs. Moreover, according to this publication, support frames of the wall elements and the bracing device according to the invention, as well as the displacement of the support frames relative to the cover plates, are missing, which are constructed from U or C profiles. In contrast, the design according to the invention not only brings about an essential, in practice particularly valuable simplification of the assembly work, but also a particularly secure mounting of the wall elements and their particularly good alignment or adjustment facility in the building.

In the construction which became known from DD-PS 107 326, a special bending of the profile legs of the upper bearing part, which makes it easier to set up the wall elements, is also missing, as is the profile receiving it in a supporting frame (see in particular FIGS. 2, 5 and 6).

DE-OS 26 44 559, in particular its Fig. 4, shows a U-shaped bearing part for a wall part on the ceiling; whose legs are not bent in the manner according to the invention. A complicated connection between this bearing part and the wall part is provided via a special profile, additional plastic elements being required in particular (FIG. 12). The manufacture and assembly are therefore complex. Support frames and bracing devices within the meaning of the invention are also not present in this known design.

According to the invention, the adjacent wall element can be aligned. It is sufficient according to the invention if the bearing part is shorter, in particular considerably shorter, than the legs of the frame profile interacting or engaging therewith. The insertion the wall elements, in particular from their edges, especially the upper frame profiles, to the bearing parts is made possible according to the invention if only half the lower legs of the bearing part profiles are beveled towards the center thereof. Installations can be accommodated particularly well if the leg ends (parts) of the bearing part enclosing an acute angle with the profile center plane are connected to leg ends bent approximately normal to the profile center plane, these bends being significantly shorter than half the web length of the U- or C- Are profiles. The strength and possibly the load-bearing capacity of the arrangement can be increased if at least one support designed as a U or C profile between an outwardly open and an inwardly open U or C profile of the frame is provided in the interior of the support frame of the wall element this is arranged bracing.

According to the further embodiment of the invention, a particular stiffening of walls and their alignment over their entire height is achieved in that the lateral U or C profiles of the support frame have profiled webs, in particular those with depressions and elevations with an approximately trapezoidal cross section, which correspond to the side profile of the adjacent wall element in the case of side-by-side arrangement of wall elements, that is to say they interlock like tongue and groove, and that these webs are extended beyond the outer leg surfaces of the U or C profiles, so that these web extensions represent a partial support for the cover plates .

A particularly favorable bracing of the prefabricated wall parts after their support on the above-mentioned bearing parts can be achieved according to the invention if the web of the U or C profile of the support frame, which is arranged in the wall element region remote from the bearing part, in particular on the bottom side of the wall element or has several openings, in which a plate is suspended, which carries a thread, into which an adjusting screw is screwed to compensate for differences in the dimensions of the wall element and the building part accommodating them, in particular differences in the distance from the ceiling and floor, the Bolt is guided with play through an opening of the aforementioned web and whose head is against the neighboring part of the building, in particular the ground. Additional adjustment options are provided if between the web of the U or C profile of the support frame, which is arranged in the wall element area remote from the bearing part, in particular on the bottom side of the wall element, and the adjacent wall element edge or the floor at least largely within the cover plates an, advantageously interchangeable and hollow, spacer, in particular a U or C profile, is provided, which bears against this web, and has one or more openings in which a plate is suspended, which carries a thread into which one Adjusting screw to compensate for differences in the dimensions of the wall element and the building part accommodating them, in particular differences in the distance from the ceiling and floor, is screwed, the bolt of which is guided with play through an opening in the spacer and, if appropriate, the aforementioned web, and the head of which is against one another supports the neighboring part of the building, especially the floor.

Further adjustment options, in particular in the horizontal direction, are achieved according to the invention in that the support frame held at the top by the bearing part which only extends into the space between the cover plates with bent leg ends and comprises at least one closed part which is permanently connected to the cover plates and at least one part in or on this displaceable open frame part or profile, which is releasably connected to the cover plates, the cover plates can be trimmed at least in the region of the displacement path of the open frame part and the outer dimensions of the profiles or profile parts of the open frame part displaceable in the closed frame part are smaller are as the internal dimensions of the profile parts of the closed frame part receiving these profile parts. This allows a good adaptation to the wall widths or lengths desired, even if only industrially manufactured wall elements are delivered.

The work of the building trade, in particular installations, is facilitated or greatly simplified if, according to the invention, at least two closed frames, which are arranged one above the other, are arranged above the bearing part with bent leg ends that only extends into the space between the cover plates, the uppermost or the upper frame has a U or C profile which is open at the top and which surrounds the above-mentioned bearing part with inwardly bent profile legs, and has a U or C profile open at the bottom, which can rest on a U or C profile which is open at the bottom of a closed or open frame immediately below it and which, when closed, has a U or C frame open at the top C-profile has as a lower limit and, if necessary, in the profile spaces of these two profiles of the lower closed frame, at least two standing or vertical profiles, in particular U or C profiles, are slidably arranged, between which supporting wood or the like. can be arranged. Wash basins and their valves can be attached to such supporting timbers, and these supporting timbers can already be delivered arranged in the wall elements between the cover plates; for example, they are then brought into place on the spot after a corresponding displacement of the standing profiles in the lower part of the frame. Openings for windows or pass-throughs can also be provided in this or a similar manner, with a lower frame located underneath with its uppermost or upper and downwardly open U or C profile at a distance below the last-mentioned open U or C-profile is arranged and the cover plates are interrupted in this spacing area.

Depending on requirements, stiffeners can be introduced into the support frame in order to increase or modify the load-bearing capacity of the support elements depending on the area of application. This can be achieved, for example, in that the closed frames are additionally supported by standing or vertical profiles in the interior and, if appropriate, stacked closed frames are provided between additional standing or vertical profiles located within the cover plates, these profiles forming the side profiles of these frames and run parallel to the standing or vertical outer profiles of the wall elements.

If you want to take particular account of ceiling deflections, then according to the further embodiment of the invention, the height of the wall elements held above by the bearing part, which only extends into the space between the cover plates with bent leg ends, can be chosen to be lower than the interior height, under certain circumstances after actuation of the tensioning device or the like, especially the distance between floor and ceiling, so that the legs of the uppermost U- or C-profile of the support frame open to the bearing part encompass this bearing part only in the lower region of these legs, and also bridge the distance between the wall element or its cover plates and the ceiling by means of elastic angle profiles, for example made of rubber.

In selected cases, the attachment of the wall parts is additionally facilitated according to the invention in that the bearing part has two different, in particular different long legs which extend or can be inserted into the space between the cover plates.

The work of the building trade, in particular the carpenter and electrician can be facilitated according to variations of the invention in that openings for doors or windows are formed between U- or C-shaped standing or vertical profiles of closed or open lower frames, the webs of which Profiles lie at these openings and, for example the opening edges with steel frames or the like. are provided, for example, for lock cases or hinge bearings, etc. have special recesses and or or that in the top U or C profile or in the bearing part and, if necessary, between the cover plates, insulating tubes that can be flexible for electr. Lines or the like are provided, and that at least one opening in the web of the uppermost profile of the support frame and optionally below it openings in cover plates for introducing electrical lines and / or openings in side profiles and / or in floor or intermediate profiles of the support frame are provided.

Exemplary embodiments of the invention are described below with reference to drawings. 1 shows a vertical section through an arrangement according to the invention of a wall element with associated bearing part and a spacer profile and a bracing device at the lower edge of the supporting frame, FIGS. 2 and 3 in a diagrammatic representation of ceiling connections of the wall element, FIGS. 4 and 5 also in a diagrammatic representation Floor connections of the wall element, FIGS. 6 and 7 mobile partitions, also in a diagrammatic representation, etc. the ceiling, floor and side connection, Fig. 8 two variants of the ceiling connection, Fig. 9 to 9e and Fig. 10 a fixed frame design, Fig. 11 to 11g such a variable width in its greatest extent, FIGS. 12 and 13 in the pushed-together state, FIGS. 14 to 14i a frame construction for a wall element with a central hatch, FIGS. 15 to 17 the adjustment means at the floor connection, FIG. 18 a profiled side profile of the support frame in cross-section, Fig. 19 the section through a symmetrical and - dashed - through an asymmetrical bearing part, Fig. 20 a modification of an inner wall joint, Fig. 21 a similar design with a joint cover, Fig. 22 to 24 a prepared for electrical installations Wall element, FIGS. 25 to 25i and 26 to 29 such a for sanitary installations, FIGS. 30, 30a and 30b a detail for an inner wall door, FIG. 31 the contact of two inner walls standing at right angles to one another and finally FIGS. 32 and 32a one between the inner wall ceiling and the inner wall. The introduction of a wall element into the bearing part according to the invention is illustrated in FIG. 33.

In the following, the same reference numerals are used for corresponding or similar parts.

1 to 14i, the wall element, generally designated 1, consists of a metal, in particular steel, support frame 2, which has edge profiles 3 and cross profiles 4. FIGS. 2, 3 and 8 each show only a section with an edge profile 3 and the upper cross section 4 and in FIGS. 4 and 5 a section with the lower cross section 4 of the support frame 2 is shown. Cover plates 5 and 6, for example plasterboard, which have sufficient inherent rigidity, are fastened in a suitable manner to this frame formed from the edge and transverse profiles. This can be done, for example, by screwing, nailing, gluing, etc. These cover plates can be cut on the spot. In the embodiments shown in FIGS. 1, 5 or 6 and 8, the possibility of trimming in height for the wall element 1 is given by the fact that the lower or upper transverse profile 4 in relation to the edge of the plates 5 and 6 by a large amount of trimming the interior of the element 1 is arranged set back. The resulting cavity in the edge area of the element 1 is filled in the bottom area by an interchangeable and thus freely selectable spacing profile 7, particularly in height, which is only inserted in the element 1 or is easily detachable is. In this area, the two cover plates 5 and 6 are only attached to the transverse profile 4 or to the edge profiles 3. It is therefore easily possible, by trimming the element 1 at the lower or upper edge, to adapt the height of the element to the given dimensions of the space in which the element is to be set up, without impairing the load-bearing construction of the element. In addition, the element 1 is provided with bracing devices or adjustment supports 8 in order to compensate for dimensional differences or unevenness in the floor. This bracing device can be seen more clearly from FIGS. 15 and 16. In the embodiment shown, the bracing devices or balancing supports 8 consist of a plate 9 which is detachably fastened to the lower transverse profile 4 or to the spacer profile, in particular can be attached or plugged on, and has a threaded hole 10 into which a (set) screw 11 with a support head 12 is screwed (Fig. 15,16!). The lower cross section 4 and, if applicable, the spacer section 7 located below are provided with corresponding openings or bores 13 and 14 for receiving the (Ver) adjusting screw 11 and for hanging the plates 9 (FIG. 17!). 15 and 16 show hooks 15 on the plate 9, with the aid of which it can be attached to the lower transverse profile 4 or to the spacer profile 7.

Of particular importance for the present invention is the bearing part 16, which is initially attached to the ceiling 17 for the purpose of installing and securing the wall elements during assembly. This bearing part 16, which can be designed symmetrically (FIGS. 1, 2, 3, 4 and 5) or asymmetrically (FIG. 19), has beveled leg ends 18 towards the center, which are also at the outermost, in particular lowest, end 19 towards the center of the profile can be bent at right angles to the profile center plane, etc. for stiffening the profile or for better storage of pipes 20 for electrical installations (Fig. 3). These bearing parts 16 - as indicated in FIG. 33 - particularly enable threading or insertion of the wall elements 1 during the installation process and, if they are arranged in the region of the parting joint of adjacent wall elements 1, that is to say adjacent wall elements 1, can align such adjacent elements Ensure elements 1 (Fig. 2,3,6).

1 to 11g and FIGS. 12 and 13 in addition to the above-described height adjustment by means of the adjusting screw 11 or interchangeable distance profiles 7 a possibility for adjusting the width of the element 1 is shown. An adjustment or cutting ability in the width can be given in the same or similar manner as for the height adjustability, in that edge profiles 3 are set back inside the edge of the element 1 and interchangeable distance profiles are provided or doubled like the distance profile 7. According to FIGS. 11 to 13, one possibility for circumcision, which is particularly shown here, is that support frame parts can be laterally displaced relative to one another. For this purpose, a U-rail part 4 'or 4˝ of the cross section 4 is attached to the upper and lower end of the edge profile or upright 3, which projects transversely from the edge profile or upright 3 and in the cross section part 4 ‴ or 4 ^IV rests. The connection of the mutually displaceable cross-section parts 4 ', 4 ‴ or 4˝, 4 ^IV can or the like by means of screwed in at the points indicated by points 4 ^V , 4 ^VI , self-tapping screws. take place, which are screwed through the cover plates 5,6.

The wall element shown is filled with a filling 21 made of heat and / or sound-insulating material, which preferably also has fire-retardant properties, e.g. Mineral wool, provided. The filling 21 is compressible or can also be cut at the edges for the purpose of adapting the wall element.

15 and 16, the (Ver) adjusting screw 11 and the nut 9 are shown in more detail on an enlarged scale. According to FIGS. 4, 5, 6, the (Ver) adjusting screw 11 has a hexagon socket 22 and a centering anchor tip 23, on which hexagon socket a screw wrench can be attached in order to adjust the screw 11 in the threaded bore of the nut 9. The head part 12 of the (ver) adjusting screw 11 is provided with the centering projection 23 which is arranged coaxially to the screw axis and which can be pressed into the ground. The nut 9 is formed as an approximately rectangular plate, in one edge area of which the aforementioned hooks 15 for attaching or fastening this nut 9 are attached to the lowest cross profile 4 or to the spacer profile 7 or in the openings thereof.

The drawing shows both the secured deck connection and the size of the adaptability of element 1 to the premises.

In the position shown in Fig. 4, the minimum position, the wall element 1 is cut off to its largest circumference, i.e. to the lower edge of the lower cross section 4, the height adjustment 11 being screwed back to the lowest level, and thus the cross section 4 resting almost on the underbody level.

1 and 5 show an extensive or maximum height position of the untrimmed element with respect to the underfloor level 27 of the room. The (adjustment) screw 11 is shown in the most unscrewed position. The resulting gap between the lower edge of the element and the lower floor level 27 may be covered by the floor construction 28, 29 which is only applied later (FIG. 5).

2 and 3 also show how the bearing part 16, the web 25 of which is profiled, can be fastened to the ceiling 17 in a favorable manner: slots 26 are provided for this purpose, so that certain displacements of the bearing part 16 are made during the fastening process can be.

6 and 7 show a mobile partition in longitudinal or cross section. Fig. 7 illustrates the side joint of two adjacent walls. The edge profiles 3 of the support frame have a profiled web 30. This web profiling can, as here and also in FIGS. 9b, 9d, 11c, 11e, 13, 14b, 14f, 25b, 15d, 28 and in particular in FIGS. 18, 20 and 21, which have trapezoidal elevations 31 and depressions 32 in cross section, elevations of the one edge profile 3 or its web 30 of a wall element 1 are respectively fitted into depressions of the edge profile 3 or its web 30 of the adjacent wall element 1. In the mobile partition shown in FIG. 7, the cover plates 5, 6 are set back from the webs 30 of the edge profiles 3, so that free joints 33, 34 arise after installation, into which, on the one hand, a C or U profile 35 is inserted and which are bridged on the other hand by a cover 36. Mineral wool 21 is also provided in the interior of the wall elements for insulation or soundproofing, as can also be seen in the lower part of FIG. 6. For such walls, the bracing devices 8 to 12 already described above with a set screw 11 at the lower edge of the wall elements 1 are also favorable, for which reference is made to the lower part of FIG. 6, which also has an insulation strip 35 below the set screw 11 or its head 12 and a skirting 36 to cover the gap between the lower edge of the wall ment and the floor. In practice, the cover plates 5,6 are usually provided with wallpaper 37 or a coat of paint.

If the ceiling span is large, there is a risk of deflection, especially of the ceiling beams. In such cases, it can be advantageous to design the upper part of the wall element arrangement, as can be seen from the left part of FIG. 8. Cover plates 5 and 6 and the flanges of the upper frame profiles 4 end after the installation of the wall element 1 at a distance from the ceiling 17, so that when they bend, the edges of the cover plates 5, 6, in contrast to the design shown on the right in FIG. 8 not affected by the ceiling and possibly damaged, and the bearing part 16 can slide with its flanges within the flanges of the profile 4, because the ends 18 of the flanges of the bearing part 16 have a distance from the web of the profile 4 after assembly. To close the gap between wall element 1 and ceiling soffit 17, suitably elastic sealing strips, e.g. a rubber seal 38 with an angular cross-section can be used.

The structure of the frame 2 stiffened by a center column 39 with a profile cross section according to FIG. 9c according to FIG. 9 is additionally illustrated with the aid of the profile section representations 9a to 9e and above all by means of FIG. 10. For special clarity, the profile section representations with FIGS. 9a to 9e are located directly at the corresponding profiles of the support frame. The upper edge profile 4 of the frame also remains open in the area of the side profiles 3 in order to be able to arrange or pull through installation pipes 20 (see also FIGS. 1 and 3) and electrical lines over the wall element side flanks. The edge profiles 3 and also the middle profile 39 have corresponding cutouts 40 at the top, i.e. So those that largely resemble the outer surface of the edge profiles 4 (see Fig. 10!).

The adjustable with respect to the side dimensions of Fig. 11 is made up of two subframes 2 ', 2˝, the stiffened by a post 39 frame 2' also consists of the profiles 3.4 ‴ and 4 ^IV under the subframe 2˝ the profiles 3.4 'and 4˝ is composed. As already indicated above, the profile parts 4 'and 4˝ in projecting profile parts of the profiles 4 ‴, 4 ^{IV are} initially displaceable stored, whereby after completion of the assembly, the aforementioned securing of the parts 4 ', 4˝ and 4 ‴, 4 ^IV to each other. The cover plates are only connected to one of the subframes, in particular the subframe 2 'before assembly, so that the remaining part of the cover plates can be trimmed in accordance with the required displacement of the other subframe. After completion of the assembly, the remaining cover plate areas are then connected to the fully moved subframe 2 fertig. The individual profile cross sections again show the secondary figures associated with the associated profiles, FIGS. 11a to 11g. 12 and 13 also show the frame parts in elevation (Fig. 12) from the opposite side and in plan view (Fig. 13), etc. in the extended state (dashed lines) and in a pushed together form, i.e. with the smallest side extension of the wall element. Gypsum plasterboard, impregnated building boards, fire protection boards, gypsum fiber boards, asbestos cement boards, cement-bonded particle boards, but also other building boards may be used depending on the needs and intended use.

In the frame construction according to FIG. 14 with an opening 41, in particular for a hatch, partial frame structures 42, 43 are provided above or below within a main frame 2 with the four outer profiles 3, 4, for which purpose the adjacent or below or 14a to 14i above the profile cross sections can be seen.

18 shows a cross-section of a side profile 44 of the support frame 2, which has special webs 45 which protrude beyond the side surfaces of the profile flanges. These webs 45 can serve as supports for the cover plate edges or the reinforcement. Additional bends 46 can be provided for these at the flange ends.

The bearing part 16 shown in section in FIG. 19 preferably has legs 42, 43 of the same length, but may also be designed with legs 42 ', 43' of different lengths, the leg bends 18, 18 'including different angles with the profile symmetry axis 44 or can be of different lengths. Such inequalities can facilitate assembly, but can also serve installation purposes, in particular if the additional bends 19 already mentioned above are present.

Fig. 20 shows a plan view of an inner wall joint, which differs from the embodiment according to Fig. 7 insofar as practically the profile joints are omitted and the cover plates 5, 6 sit on the previously mentioned additional webs 45 and there are also bends 46 to the inside. The plates 5, 6 are plasterboard, the frame 2 consists of steel profiles and mineral wool is provided as insulation 21. Fig. 21 shows a detail of a similar design, but the small existing parting is covered by a strip 47.

22 to 24 illustrate in a partially opened top view (FIG. 22), side view (FIG. 23) and in a view of the upper or lower narrow side of the wall element, one for electrical installations. The opening 48 in the cover plate 5 is used for threading electrical lines and later for the installation of junction boxes. Electrical lines or cables can also be laid in the upper profile 4, from where the lines can also be led down through openings 49 in the web of this profile, with, in particular, flexible, installation or insulating pipes 50 between the cover plates 5, 6 Can take lines. Further openings 51, 52, 53 and 54 are provided on the side profile 3 or on the base profile 4 or on the cover plate 5 in order to continue the lines or to attach switches, sockets or junction boxes. The last-mentioned precautions in a special wall element facilitate the use of industrially prefabricated wall elements in the design of buildings. The same applies to sanitary installations for wall elements according to FIGS. 25 to 29, although the upper subframe 2 'according to FIG. 25 shows installations for electrical installations in the sense of FIGS. 22 to 24. In contrast, the lower subframe 2˝ is prepared for sanitary installations. The cuts according to FIGS. 25a to 25i, which are also assigned to each of the adjacent profiles of the support frame, clarify the mechanical structure of the support frame. In the lower part of the frame 2 versch there are slidable uprights 55,56, between which wooden plates 57,58 (see also Fig. 29!) Can be used, etc. at any height within the lower subframe 2˝. The cover plate 5 of the lower subframe 2˝ is detachable or is fastened after arrangement and adjustment of the mounting plates 57, 58, whereupon the sanitary installations are completed, for example a washstand and valves, etc., can be installed without requiring special manipulations at the construction site.

30 shows a variant, FIGS. 30a, 30b show a further variant in a horizontal partial section through a wall element 1 in the region of an inner wall door 59 or in a diagrammatic representation thereof (FIG. 30a), with specially designed steel frames 60 or Stops can be used for the door. The frame has a recess for a lock case 62. The steel frames 60 and the stops are provided with recesses 63, 64 which are foamed or filled with plastic. The frames 60 are mounted on profiles 3. 30a, 30b show a spacer plate 61, a transport stiffening 61 'and screw connections 61˝.

Fig. 31 shows the butt joint 65 between two inner walls, which is foamed in the area between the side profile 4 and the adjacent cover plate 5 with plastic. 32 and 32a show a similar situation in the plan and in a diagrammatic representation when the inner wall and ceiling contact, with an additional plaster strip or the like. 66 is present and the joints 67, 68 are again foamed or filled with plastic. The edge profiles are again labeled 3 or 4.

33 schematically illustrates with particular clarity the advantage of the invention insofar as it relates to the installation of the wall elements 1 with the aid of the aforementioned special bearing parts 16 with angled leg ends 18. The wall elements 1 are brought up from the left in an inclined position in the direction of arrow A, in particular driven and then or thereby brought into the position shown for the bearing part 16, which was previously on the ceiling 17, for example by screws 69 in slots of the web of the Bearing part 16 was attached. The wall part 1 is then brought into a vertical position by pivoting in the direction of the arrow B, with the legs of the profile 4 resting against the legs of the profile 16. This represents a considerable relief in the assembly of the bulky, heavy wall elements, the naturally open upper edge profiles 4 of the support frame 2 also being important. The above-mentioned bracing devices on the lower edge of the wall element complement the inexpensive assembly method made possible in this way, while the detachable or exchangeable distance profiles and the ability to trim the cover plates are valuable additional measures represent. The special arrangements for installations in prefabricated elements bring considerable relief for the construction site. Otherwise, the measures shown with regard to the main elements can also be provided rotated through 180 °. Thus, the bearing part 16 can be arranged on the floor and a bracing device on the ceiling, in the area of which distance profiles or the like can then also be arranged. would have to be provided. The same applies to the sides of the wall elements. Wedges or the like may also come as bracing devices. in question.
