Abstract

The frame (2) comprises two or more profiled vertical members (3), between which one or more cross-members (35) are fixed, accommodating fittings etc. Lugs on the cross-member ends fit in holes in the vertical members. Each of the cross-members is of rolled box-section, on which a lengthwise rib (5) is formed on the outside. This contains a row of holes for the cross-member lugs. The ribs can be on the sides facing towards each other of the two vertical members, the holes in them being at the same levels. Each rib can be formed by a folding operation, so that it has three times the wall thickness of the remainder of the rib. There can be a locking plate screwed to each end of the cross-member and pressing against the rib, so as to pull the respective lug into the hole and hold it there.

Description

The invention relates to a pretext element for plumbing with a Frame made of at least two vertical struts essentially formed from hollow profiles and at least one substantially transverse to the vertical struts arranged, attached to the vertical struts for receiving and Attaching attachments, with at least one in each of the vertical struts is arranged substantially along the longitudinal extent of the perforated grid row, in the corresponding locking lugs on the crossbar or on a connectable with this Device can be inserted and locked.

Such a pretext element is known from DE 94 12 649 U. The pretext element includes C-shaped vertical profiles, on the open side of which are transverse Slots are arranged in the crossbars of the trusses can be used. The fixation the crossbeams are then made using washers and screws.

The general problem with pre-wall elements is that they have to be adapted different add-on elements including their different arrangement heights must be designed accordingly. Because of the variety of growing options a variety of mounting options required, one is in the state of the Technology has gone over to the vertical struts according to the desired Position the crossbar with mounting holes. This configuration either made a very large inventory of pretext elements because of that required large versions, or this work was done on site left to the installer. The connection of the trusses to the mounting holes then took place via appropriate fastening screws. Understandably had to go through these trusses, especially with heavily loaded trusses appropriately sized fasteners are held.

Furthermore, from GB 1 169 620 A an element in stand construction is known that has an open vertical profile, on the back two at a distance and parallel mutually arranged flanges are present. In the slot between the Flanges, a tongue of trusses is inserted and holes in the flanges and screws. In the adjacent back areas Holes exist in the hooking elements from perpendicular to the first trusses arranged plate elements are hooked.

It is now the object of the present invention to provide a pretext element Provide the type mentioned that the desired flexibility in terms of provides the required cultivation options.

This object is achieved by a pretext element with the features of claim 1 solved.

This solution offers the enormous advantage that the vertical struts continue from one very simple hollow profile can exist, which has a whole series of locking holes has, each for connecting the crossbar in a different position the vertical struts can be used. This allows manufacturing, reduce storage and the associated costs by a significant amount. Furthermore, the installer is not expected to do the appropriate Make mounting holes at the desired locations on the vertical struts. The engagement of the locking lugs in the hole grid row ensures that the crossbar supported directly on the vertical struts. All you need is a fastener, this prevents the locking lugs from accidentally coming out of the locking holes can slide out if there are no corresponding undercuts or have similar. Such fasteners do not transmit the entire Payload and can therefore be much cheaper and smaller than in the state of the Technology. Understandably, the perforated grid row is chosen so that all existing mounting variants are covered by these. In this context could on the vertical struts e.g. appropriate markings attached be, so that the installer only for the traverse in the appropriate place hangs and locks the desired attachment. This leads to an enormous Time saving, since further alignment is also possible thanks to the defined system of the There are locking lugs in the locking holes. The attachment of the longitudinal web to the Vertical struts can be used without complex connection techniques, e.g. Welding, in such a way that the vertical struts with a roll-formed box profile laterally formed longitudinal web is formed, the row of perforations in the longitudinal web is arranged. The manufacture of vertical struts can therefore essentially to do this continuously to an almost unlimited extent. Furthermore is the manufacturing technology for the production of roll-formed box profiles has long been known and thus well established in technology, which results in lower manufacturing costs Has.

Advantageously, the perforated rows of two vertical struts to one another be aligned such that the locking holes are each essentially the same Height. With this configuration, it can be done in a very simple manner Place a crossbar horizontally between the vertical struts.

The longitudinal web can preferably be produced by a rolling process, so that it 3 times the wall thickness compared to the remaining hollow box section of the vertical strut having. As a result, the longitudinal web itself is a very large one Strength and thus carrying capacity and on the other hand this of the entire Vertical strut gives good rigidity.

The locking of the traverse on the vertical strut can thereby preferably take place that the traverse by a screwed at its end areas Locking plate, which is essentially in one plane on the longitudinal web of the Vertical strut and an area of the crossbar is supported such that the Locking lugs are pulled into the locking holes by the pressure of the plate and locked are. With this variant, it is also not necessary that the locking lugs have a shape with undercut, as they are due to the pressure of the plate in the locking holes being held. The locking plate can also be suitable means for accurate Have positioning on the crossbar, so that the locking lugs also on the Locking plate can be arranged.

In recent times there have been calls for quieter sanitary installations always louder so that to reduce noise at the junction at least one sound decoupling element between the longitudinal web and the cross member can be provided.

The following is a pretext element with one between the two vertical struts arranged and releasably attached to this cistern reference.

It differs from the prior art in that the locking pin has one the cistern adapter connected to the cistern row in the row of holes Vertical struts inserted and also on the cistern adapter Arranged locking element are locked. Using the locking holes in the Vertical struts can now also cisterns of any width and mounting opening arrangement by means of the cistern adapter on the frame of the invention Pre-wall element are attached. He also needs for the cistern Installer no longer to provide separate holes on the vertical struts, so that it can be attached to the frame of the pre-wall element. By the use of a locking element allows the cistern to be very quickly in its Adjust the height by inserting the locking pins into another locking hole in the row of perforations be put.

Advantageously, the parallel distance between the base from which the Protruding pins protrude and the locking area of the resilient locking element in correspond essentially to the thickness of the longitudinal web on the vertical strut, so that when inserting the locking pins into the corresponding locking holes, the locking area the locking element moved away by the pressure of the web and then behind one side surface of the web resiliently engages. Because the locking area of the locking element on the opposite side of the Longitudinal web presses on this, the locking pins are best in the locking holes pulled and the cistern adapter thus firmly on Longitudinal claws.

A simple connection of the cistern to the cistern adapter can be done in that the cistern adapter hook elements and has associated resilient pressing lugs, which in corresponding Recesses can be hooked into the cistern and locked. This Hook elements can easily be attached to the corresponding ones Customize cistern designs so that a universal Usability is given.

To also reduce the noise emanating from the cistern, is the cistern adapter in a further embodiment preferably made of plastic as a sound decoupling element educated.

The pre-wall element 1 used for the sanitary installation can designed modified for the various applications e.g. show Figures 1, 3 and 4 a pretext element WC installation and Figures 5 and 6 a corresponding Wall element for attaching a wash basin and fittings. The individual configuration will be discussed in more detail below received. But there are also other conceptions of Pre-wall elements, especially regarding the extensions, conceivable, which are adapted to the different applications, e.g. Shower, bathtub, urinals, bathroom furniture etc.

The pre-wall element 1 has a frame 2, which consists of two Hollow profiles formed vertical struts 3 and one from one open hollow profile, preferably a C-profile, which formed Vertical struts 3 holding cross strut 4 at a distance from one another.

As can be seen in particular from FIG. 7, this exists Hollow profile of the vertical struts 3 from a roll-formed Box profile, preferably rectangular cross-section, with a one-sided, in the middle of a shorter transverse side of it, arranged longitudinal web 5. The longitudinal web 5 has three times Material thickness of the rest of the hollow profile, since he by folding the one sheet end was made over the other sheet end. Galvanized sheet steel is preferably used as the material painted before profiling or with a colored film is coated.

The C-profile of the cross strut 4 and the box profile of the vertical struts 3 preferably have the in this embodiment same opening cross-section on the inside. The respective End openings 6 and 7 of vertical strut 3 and cross strut 4 serve as receptacles for a corner connector 8, with its Plug approaches 9 and 10 in the end openings 6 and 7 accordingly in intervenes substantially to fit. As can be seen in the figures is, the two plug inserts 9, 10 are at 90 ° to each other staggered so that the corner connector 8 has an L-shape receives and the lugs 9, 10 represent the L-leg. The Corner connectors 8 form at least the upper corners of the frame 2. A central area 11 of the corner connector 8 forms the visible corner. For this purpose, this central region 11 is preferably the Adjusted outer contour of vertical struts 3 and cross strut 4 or stands over this. With this configuration Stop surfaces 12 are formed, on which the perpendicular to their Vertical struts 3 and cross strut 4 cut along the longitudinal axis can strike flat. When connecting the struts 3, 4 by means of the corner connector 8 is thus automatically high Dimensional accuracy made.

Furthermore, each plug insert 9, 10 has a cross to threaded hole 13, 14 extending in the respective insertion direction, into the appropriate screws for attachment to the struts 3, 4 are screwable. With the cross strut 4, this can be done parallel to the longitudinal opening arranged guide opening 15 used become. The vertical strut 3 can do this accordingly Have opening 16. The attachment e.g. on the vertical strut 3, can also be done such that in the threaded bore 13 a Countersunk screw is inserted that does not have the outer surface of the projection 9 protrudes, and the opening 16 a Has diameter that is smaller than the head of the used Screw, but is large enough to be accessed by a tool to ensure the screw head. The screw head can then against the inner wall of the vertical strut 3 when inserted Corner connector 8 can be clamped. In this embodiment can also attach the corner connector 8 to the struts 3 done from the front of the frame 2 since the Do not protrude fasteners.

In Figures 8 and 9 it can be seen that the corner connector 8 with its plug inserts 9, 10 also as e.g. aluminum die or plastic injection molded part can and for this reason corresponding stiffening ribs and Have cavities 17 to avoid material accumulation can.

In the central area 11, the corner connector 8 has a fastening point 18 in the form of a through hole through which a screw 19 can be inserted, on the shaft Snap ring 19a is clamped to rotate the screw 19 in the Fix through hole, and its thread on the back the corner connector 8 over a large area, e.g. 10 centimeters, protrudes. The screw 19 provides a pivot axis for one Fastening tab 20, which is corresponding to receiving the Screw 19 has a threaded sleeve 21 arranged thereon. The Mounting bracket 20 is used for wall mounting the Wall element 1 and accordingly has an elongated hole 22 through which wall mounting screws are inserted can. By turning the screw 19, the distance of the Adjust the mounting tab 20 to the frame 2 so that the corresponding pretext elements 1 for a relatively large Wall distance range can be used. 8 are different screwing states are shown.

According to another variant according to FIGS. 7a and 7b is a Snap ring 19b in the through hole in the corner connector 8 used that this the head of the screw 19th axially in the through hole. The screw 19 is then rotatably held in the corner connector 8. The main support force is from the screwed on the thread of the screw 19 nut 19c and washer 19d, which are against the vertical strut 3 support, transfer.

Furthermore, it can be seen from FIG. 8 that the fastening tab 20 also as e.g. Aluminiumdruckgußelement or plastic element can be executed. 8 is from also recognize that on the back of the Fastening tab 20 a hook element 23 from the rest Contact surface of the mounting bracket 20 is set back is. The hook element 23 is in a position in a corresponding Guide opening of a C-profile rail attached to a mounting wall to be hooked up. This allows assembly simplify the pretext elements 1 very much. If necessary Attachment to a C profile rail via a bore 24 respectively. From Fig. 9 it can also be seen that the Fastening tab 20 can also have a plurality of elongated holes 22, to increase the number of different mounting options increase. Since the mounting bracket 20 on the pivot axis on Center region 11 of the corner connector 8 is pivotable, it can can be attached to the mounting wall in various positions.

The end region 25 of the fastening tab arranged around the threaded sleeve 21 20 has a concentric to the pivot axis Rounding off with a radius that is essentially the shortest Distance A of the pivot axis on the corner connector 8 to the latter corresponds to the outer edge or to the upper edge of the cross strut 4. This ensures that the upper edge of the end region 25th and the top of the corner connector 8 together in one Front of the frame is 2 vertical plane. This is particularly advantageous if the top of the pretext element 1 as a support for a storage surface arranged thereon should be used. These elements that make up the shelf e.g. a gypsum fiber cement or gypsum board, are then also in the wall area on the support areas of the end areas 25 on and are automatically at the appropriate angle to the front of the Wall element 1 aligned.

The above-mentioned plug-in construction of the frame 2 continues to offer the advantage that the struts 3, 4 are not in a subsequent Operation must be welded. Because of the simple Putting these components together is both a stable, as well an extremely precise design of the frame 2 possible, so that a string of several pretext elements 1 through the high dimensional accuracy is far less problematic than in State of the art. In addition, the attachment of the pre-wall elements through the attached to the corner connectors 8 pivotable mounting brackets 20 greatly simplified. The For the sake of completeness it should be mentioned that the attachment of such Fastening tabs 20 in other places of the Wall element 1 for the appropriate support of attachments can be used.

FIGS. 5, 6, 11 and 12 each show an embodiment of the Wall element 1 shown, in which the lower end openings 6 of the Vertical struts 3 for receiving a substantially precise fit Serve guide rails 26 which in the vertical struts 3rd are held telescopically. The guide rails 26 are perpendicular to the longitudinal extent of a lower cross strut or Bottom rail 27 arranged and attached to this. In the in the Figures illustrated embodiment are as Guide rails 26 C-profile rails inserted. The baseboard 27 has fastening openings (not shown) for attachment to Floor or a C-profile rail attached to it. At the the lower end region of the vertical struts 3 is also located an opening 16 through which a screw 28 can be inserted. In the interior of the vertical struts is specially designed Clamping nut introduced, in which a threaded bore 30 for Screw in the screw 28. The lock nut 29 will thus inside the lower end region of the vertical struts 3 held. The clamping nut 29 looks approximately V-shaped in cross section from, so that essentially two clamping legs 31 are formed. On At one end of the lock nut 29 is a pin 32 on the a bow spring 33 is pressed with its central region. The Bow spring 33 has two spring arms 34, the deflection of which is transverse to the direction of insertion of the guide rails 26.

The lock nut 29 is now designed so that at accordingly loosened screw 28 this from the inside of the guide rail 26th can be added while this continues over the screw 28 is connected to the vertical strut 3. The screw 28 engages thereby into the guide opening 15 of the guide rail 26. This The arrangement is particularly (screw 28 not shown) in Fig. 12 to see. Then tighten the screw 28 Clamping legs 31 on the guide rail 26 and clamp them with respect to the vertical strut 3. The bow spring 33 now has the Purpose that the spring arms 34 already in the released state Clamping nut 29 a spring force on the side areas of the Exercise guide rails 26. This spring force is preferred chosen that the entire pretext element 1 by loosening the Screws 28 are not automatically adjusted, but in his Position is held. Moving the guide rails 26 in the vertical struts 3 can only be applied after a separate Displacement force, which is particularly enormous for the installer Advantages in the assembly of the pre-wall elements 1 because he do not hold them in a certain telescopic position got to. By tightening the screws 28, the position or exact height of the pre-wall element 1 fixed. Because of that created adjustment range can with a pretext element 1 Flexibility regarding the installation at different heights very much be greatly expanded. The installer is not on certain pre-wall element heights are bound and can be adjusted accordingly adjust them according to customer requirements. At this point it is supplementary mentions that the clamping nut 29 is also e.g. Aluminum die casting or plastic injection molding with one can be correspondingly curved leaf spring, and this can Clamping nut 29 corresponding ribs and cavities to avoid of material accumulations.

The design described above with the telescopic Guide rails 26 also has the advantage that at wall-high expansions two or more pretext elements can be placed on top of each other that with the guide rails 26 provided ends of the vertical struts 3 from each other point away so that the one pretext element Floor bar 27 is now at the top and with the ceiling of the room can be connected (see also Fig. 2 right side). This configuration allows deviations in the Ceiling heights without further ado by the corresponding displacement of the Realize the guide rail 26 in the vertical struts 3.

On the basis of Figures 1, 3, 5 and 13 it can be seen that the Wall element 1 several essentially parallel to Cross strut 4 extending crossbars 35 which with the Vertical struts 3 are firmly connected and essentially to Brackets and arrangement of attachments can be used. As above mentioned, the vertical struts 3 have one in their Longitude extending longitudinal web 5, which is three times Has wall thickness of the rest of the profile (see also Fig. 14 and 15). Triple the wall thickness of the longitudinal web 5 gives it a particularly high strength and Vertical strut 3 sufficient rigidity. Furthermore, the Longitudinal web 5 also along the longitudinal extent of the Vertical strut 3 rows of perforated grids with square ones Locking holes 36 on. The locking holes 36 two a common Vertical struts 3 forming frame 2 are each on the same Height. The center distance between two locking holes 36 is preferably very high chosen small to provide as many recordings on the longitudinal web 5. In one embodiment, the center distance is about 1 cm.

The cross member 35 consists essentially of a U-shaped bent sheet metal, each with its ends accordingly Locking lugs 37 are formed, each in the locking holes 36th intervention. For this purpose, the U-web is in the end regions of the cross member 35 detached from the U-legs 39 and through a step 38 offset parallel inwards, so that at the end areas an approximately H-shaped profile is created. The U-legs 39 are with Stampings provided so that the locking lugs 37 and recesses 40 arise. The dimension of the recess 40 is chosen so that whose depth is less than the thickness of the longitudinal web 5, however the width of the front area of the longitudinal web 5 plugged latch 37 can accommodate. The end area of the Traverse 35 is a locking plate 41 with a screw 42 assigned. The locking plate 41 is supported in the Locking holes 36 inserted locking lugs 37 on the step after rear offset bearing surface 43 of the U-leg 39, while the screw 42 into the threaded bore 44 at the end of the Traverse 35 is screwed in. As a result, the locking lugs 37 firmly drawn into the locking holes 36 while the bottom of the Recesses 40 supported on the longitudinal web 5. Leave this way the trusses depending on the hole grid row Arrange any heights of the frame 2, what by simple Insert the locking lugs 37 into the locking holes 36 and tighten the Screw 42 is carried out with the locking plate 41. In this Context should also be mentioned that to simplify the Installation on the corresponding vertical struts Markers or stickers can be arranged that the respective position for the attachment of a specific traverse, e.g. WCoder Shower traverse, show.

Furthermore, it should be mentioned in advance that one designed in this way Traverse 35 with only minor modifications can be used for numerous cultivation purposes. The Traverse 35 in its central area corresponding mounting holes or threaded holes. This will be discussed elsewhere be discussed in more detail.

However, it should be mentioned additionally that not in the figures it is shown that between the longitudinal web 5 and the cross member 35th each have at least one sound decoupling element for damping Vibrations caused by attachments attached to the trusses and how they work is provided.

Referring to Figures 1, 3, 4 and 16 to 19 is too realize that attaching one between the two Vertical struts 3 arranged cistern 45 on both sides a correspondingly shaped cistern adapter 46 is used. The cistern adapter 46 has the advantage that it connects the various cisterns 45 to the row of perforations of the Longitudinal web 5 allows. The cistern adapter 46 is made preferably like the cistern 45 made of plastic and can therefore using the injection molding technique very simple one-piece be carried out. The cistern adapter 46 has a base plate 47 for attaching a corresponding flange strip 48 on Cistern 45 on. The base plate 47 is substantially T-shaped Hook elements 49 provided in corresponding Open openings 50 on the flange 48 to the To reach behind flange bar 48. So that one unintentional disengagement of the hook elements 49 have not occurred in addition to the hook elements U-shaped recesses 51, so that resilient pressing lugs 52 are formed, which accordingly intervene functionally on the flange strip 48. On the base plate 47 close on one long side two at right angles mutually aligned angle legs 53, 54 in rows. The Angle legs 53, 54 have in common, as in particular in FIG. 16 can be seen, also a substantially U-shaped Recess 55, whereby on the vertical angle leg 53rd two leaf spring-shaped arranged vertically on the base plate Elements 56 are formed. On the base plate 47 facing away Side of the spring elements 56 are on this three triangular locking elements 57. On a base 58 of the Base plate 57 are parallel angle leg 54 pyramid-shaped locking pins 59 arranged, their size and Distance to each other is selected so that it in the locking holes 36th are insertable on the longitudinal web 5. So that the locking elements 57 on Longitudinal web 5 opposite the base 58 of the angle leg 54 can lock, is the parallel distance B between the Base 58, from which the locking pins 59 protrude, and the Latching element 57 is essentially the same size as the thickness of the Longitudinal web 5. This can be seen particularly well in FIG. 20. By the cistern adapter 46 can now be easily commercial cisterns easily on vertical struts 3 from Fasten pretext elements 1 that have a hole pattern. The cistern adapter 46 is detached from the longitudinal web 5 also very simple, since the locking elements 57 for both Remove, as well as for the corresponding start-up slopes exhibit. Another advantage of the plastic Cistern adapter 46 is that this simultaneously as Sound decoupling element is used.

Based on Figures 2 and 21 to 26 are now in the following Connection variants of open hollow profiles, in particular C profile rails, described in more detail.

In Fig. 2 it can be seen that when installing pre-wall elements 1 between the individual desired extensions empty spaces must also be bridged along an assembly wall but still arranged on the pre-wall elements Gypsum fiber cement or plasterboard are covered that then preferably tiled. To get one for these items to ensure adequate support are between the individual wall elements 1 connecting struts 60, preferably in Formed by C-profile rails. To the installer To facilitate attachment of these connecting struts 60, a suitable connection unit provided, which essentially from a connecting plate 61, the openings 62 in the form of for Has the edge of the connecting plate 61 open slots, and correspondingly insertable screws 63 into the opening 62, preferably semicircular screws with square shoulder, with associated Nuts 64 is made. The openings 62 face at their closed End an approximately circular indentation 65, so that on the one side of the connecting plate 61 ridges 66 and the other Page a correspondingly assigned recess 67 is formed is. The diameter D of the increase 66 is such that it is in the substantially the width of the guide opening 15 one connecting C-profile rail corresponds. The amount of the increase E is dimensioned so that it is equal to or less than that Wall thickness of the connecting strut 60. The height E is preferred only slightly lower. The one used for this purpose Half-round screw 63 has a lenticular head 68, the Diameter is greater than the width of the guide opening 15 Connecting strut 16. Therefore, the free end areas, which limit the guide opening 15 of the connecting strut 60, at loosened screw 63 between the underside of the head 68 and the Insert connecting plate 61. The connecting strut 60 guided by the elevation 66 substantially in register. The Half-round screw 63 has one below its head 68 Square section 69, which in the opening 62 in the Connection plate 61 is slidably insertable, however, in this cannot turn. The hexagon nut 64 has on her end facing the connecting plate 61 has a guide projection 70 on, which can be inserted into the recess 67 in a substantially precise fit is. From this configuration it now follows that Connect the connecting plate 61 to a connecting strut 60 is very easy under certain circumstances even with just one hand.

If a commercially available half-round screw 63 is used, the nut 64, as in the exemplary embodiment shown in FIG. 22, can have a bore extension 71 for receiving the area of the square section 69.
So that corresponding connecting struts 60 can be connected to one another, the parallel distance C of the center of the recesses 67 and elevations 66 corresponds to one another essentially to the width G of the connecting strut 60. Furthermore, the openings 62 including the recesses 67 and elevations 66 are perpendicular in two arranged rows arranged to each other. In the example shown, there are three openings 62 in one row and two openings 62 in the other row. For this reason, the connecting plate 61 is approximately triangular, since the row with the two openings 62 is perpendicular to the center of the row with the there are three openings 63 so that their central opening 62 also belongs to the other row. The open sides of the openings 62 therefore all face away from one another. The connection unit can also be used to connect different profile strips, which means that the dimensions in question must change accordingly.

Some connection variants are now shown in FIGS. 23 to 25 shown.

23 shows a connection point at which a continuous connecting strut 60 two perpendicular to this abutting connecting strut 60 are attached. Because the Elevations 66 arranged accordingly in the associated Guide openings 15 are guided, are the two rows of openings automatically parallel and perpendicular to the continuous Connection struts 60 arranged. Moving the Connection plate 61 along the guide opening 17 is at loosened screw 23 and nut 64 very easily possible. Since the Connection struts 60 usually exactly perpendicular to it The end faces can be cut lengthwise of the two with the continuous connecting strut 60 support connecting struts 60 on this, they additionally by an increase 66 of the connecting plate 61 are led. This fact does the alignment work of the connecting struts to each other extremely easy.

24 shows a connection point at which two connecting struts 60 perpendicular to one another be connected to each other. The drawing is good too recognize that the connecting plate 61 has a triangular shape with two legs of equal length, which has a 90 ° angle lock in. Accordingly, the third leg runs to each first two under 45 °. The tips of the triangular shape associated depressions and elevations 66 are seen in series each arranged parallel to the legs, so that automatically a right angle attachment as shown in Fig. 24 is, is achievable. Furthermore, the diameter is the Recess 67 selected so that the shortest distance K between the Circumference of the recess 67 and the center line of a row to which this recess 67 does not belong to half the width of the connecting strut 60 corresponds to. This can increase the lies outside the connecting struts 60, for guidance purposes be used. Furthermore, this type of attachment shows that only two screws 63 and nuts 64 are necessary to get one ensure stable attachment.

25 shows a connection variant in which two frames 2 are connected to each other by pretext elements 1. To do this each of the fastening points 18 and the threaded bores 13, 14 and the opening 16 in the vertical struts 3 for connecting the Connection plate 61 used. The distances between the bores 13, 14 and 18 on the corner connector 8 are chosen accordingly.

Fig. 26 shows an embodiment in which the connecting plate 61 is slightly modified. So that connecting Connecting struts 60 also in two mutually transverse Levels can take place is a region 72 of the connecting plate 61 from the base plane of the remaining connecting plate 61 90 ° bent that the resulting recess 73 in essentially the external dimensions of a to be connected Connection strut 60 corresponds. The area 72 also points an opening 62 with a corresponding elevation 66 and depression 67 that continue to at least one opening 62 in the Base plane of the connecting plate 61, albeit upwards by 90 ° offset, aligned in line. This allows e.g. a vertically continuous connecting strut 60 with two on this Connect connecting struts 60 together without the a large alignment effort is required, since the two adjacent connecting struts automatically through the Connection plate 61 in one plane on the continuous Connecting strut 60 are attached.

In the variant according to FIGS. 26a and 26b, one with the Connection plate 61 connectable connection bracket 161 provided corresponding to the connecting plate 61 Embossments 65 to provide increases 66 and Has depressions 67 in its angle legs. The angle between the angle legs is preferably 90 °, so that a suitable spatial arrangement of C-profile rails 60 take place can. So that an exact positioning is carried out automatically will have two assigned increases 66 each Connection angle 161 a size and a distance such to each other that they in corresponding recesses 67 in the Connection plate 61 can be used with a precise fit. The distance of the protruding angle leg, which is inserted by the Elevations 66 on the other angle leg in its spatial Alignment with the connecting plate is precisely defined by the parallel edge of the connecting plate 61 corresponds in essentially the dimension of the perpendicular to the C-profile width G. used C-profile rail 60. The use of a separate Connection angle 161 together with the connecting plate 61 leaves numerous possible combinations of their arrangement, so that a corresponding extension of the functionality of a Pre-wall element is given.

The connecting plate 61 is preferably made of sheet metal produced and the increase 66 and the recess 67 accordingly made by the impression 65. But it is also quite possible, the connecting plate 61 made of other materials and with other manufacturing methods.

With reference to Figures 1, 10 and 27 to 30, the structure and described the operation of a support angle, the can also be used as a connecting element. The support bracket 74 has a substantially flat Support surface 75 and one arranged at right angles thereon Mounting surface 76 and a support surface 77. The Fastening and support surface 76, 77 are corresponding arranged at right angles to each other. The fastening and Support surface 76, 77 each have two fastening openings 78 in the form of oblong holes open on one side. The open side the mounting opening 78 is from the support surface 75 directed away. The center distance L of the two mounting holes 78 corresponds in each case to the fastening and supporting surface 76, 77 the width G of a C-profile to be connected by the support bracket 74, which is a connecting strut 60 or a cross strut 4, based on pretext elements 1, can be. Furthermore corresponds to the vertical distance M from the support surface 75 to Axis of the later inserted in the mounting holes 78 Screws 79 essentially half the C-profile width G / 2. In order to is when screwing on e.g. to a cross strut 4 ensures that the bearing surface 75 in one plane with the top of the Cross strut 4 or the end regions 25 of the fastening tabs 20 lies. 27 also shows how two C-profiles connected to each other by such a support angle can be. The support bracket 74 thus enables the connection of C-profiles in two levels, which is characterized by corresponding Arrangement of the support angle a number of Connection options result. Furthermore, the support angle 74 very good for supporting and attaching to the pre-wall element 1 cover elements to be attached, e.g. Gypsum fiber cement or Plasterboard can be used.

In addition, they are essentially parallel to the contact surface 75 two rows each on the fastening and supporting surface 76, 77 arranged by nubs 80. The knobs 80 have a parallel one External distance P on the width of the guide opening 16 of a C-profile rail 4, 60 corresponds. Furthermore, the Axis of symmetry of the two rows a distance M from the Support surface 75, which is essentially half the C-profile width G / 2 corresponds. The knobs 80 are used for guidance and Alignment of the support angle 74 in the guide opening 15 one C-profile rail 4, 60. This allows the support angle 74 very just align on a C-profile rail 4, 60 and under Use screw 79 and nut 81 with the C-profile rails 4, 60 connect.

The support surface 75 has an approximately L-shaped access opening 82 on, the L-leg parallel to the fastening and support surface 76, 77 are arranged. The access opening 82 allows access to a tool, especially one Wrench on which in the respective Fastening openings 78 located fasteners 79, 81. Des the access opening 82 also serves as a fastening opening the stand wall and overhead installation. For the sake of completeness it should be noted that in the bearing surface 75, as can be seen in FIG. 28 is, fastening openings and knobs can be arranged, the however, not necessarily the dimensions of the fastening openings 78 must follow on the attachment and support surface 76, 77. The Fastening and support surface 76, 77 each have bores 76a, 77a, for fastening, in particular by means of self-tapping screws on a lightweight stand wall, serve.

The support angle 74 is preferred, as shown in the figures, manufactured as a stamped and bent part from sheet metal. From the above it follows that the support angle 74 as a multifunction element can perform several tasks at once. For one, it serves as Contact surface on a pre-wall element 1 and the other he can for numerous different connection variants of C profile rails 4, 60 can be used.

In the following, FIGS. 1 to 4 and 31 to 33 are used Truss variant explained in more detail for the attachment of toilet attachments be able to.

The traverse 35 consists of, as already described above an essentially U-shaped cross-section. Of the cross member 35 also has recesses 83 in its U-legs 39 on. A connection plate is located on both U-legs 39 84, which are connected to it by means of screws is. The connecting plate 84 stands down over the cross member 35 and has an approximately T-shaped shape. The upper crossbar the T-shape covers the traverse 35 on its back and thus improves their torsional properties.

The recesses 83 of the cross member 35 are in the connection plate 84 each spring tongues 85, each in one piece with the End plate 84 are formed, assigned. The spring tongues 85 have an end region facing away from the fixed end Spring nose 86 on, in the direction of the cross member 35 on the remaining surface of the connecting plate 84 protrudes. The Spring nose 86 is located in the area of the recess 83 or, as in the embodiment shown, just below this. The recesses 83 form a guide receptacle that is covered by the connecting plate 84 for sliding Support for guide rails 87. There are 1 for each wall element two guide rails 87 each arranged on a bottom bar 27 and attached with this. The guide rails 87 extend parallel to the vertical struts 3 upwards and have a width and thickness that result in a substantially snug fit in leads the recesses 83 or the guide receptacle. As a material a U-shaped bend is preferably used for the guide bars 87 Flat steel used to be one in the direction of loading rigid, but still relatively easy to achieve. On the connection plate 84 are the extension Guide recordings leading cover elements 88 arranged. This can on the one hand, as shown in FIG. 1, by a on the cross member 35 or connecting plate 84 attached plate, or, as in Fig. 31 shown, by means of two substantially U-shaped sheets respectively. Those in the leadership recordings Guide rails 87 are closed by the spring lugs 86, as in FIG. 33 see is loaded with a spring force, so that Moving the bottom bar 27 or the guide rails 87 with respect the cross member 35 and thus the entire frame 2 of the pretext element 1 only by overcoming a predetermined force can. This force is preferably selected so that displacement due to the weight forces on the wall element 1 not done.

Locking the traverse 35 with the connecting plate 84 opposite the bottom bar 27 takes place via a stop device which in its height adjustable from the lower ends of the vertical struts 3 showing. The anchor device consists essentially of one in extension of the vertical struts 3 by means of these an associated adjusting nut 89 in and unscrewable threaded rod 90. This is in the lower end the vertical strut 3 each have a stopper 91 fixed to it the threaded rod 90 can be passed through, but one Support for the adjusting nuts 89 represents. The plug 91 can over a collar on the front side of the vertical struts 3rd support or is with this over other fasteners connected. The lower end of the threaded rod 90 is supported the bottom bar 27. The adjusting nut 89 is for Quick adjustment designed as a tilt nut so that the Installer setting as quickly as possible can make. The threaded rod 90 in interaction with the Nut 89 allows a very precise and sensitive adjustment of the desired height of the traverse 35 and connecting plate 84.

To attach appropriate attachments are either on the Connection plate 84 (Fig. 32) or on the cover elements 88 (Fig. 1) appropriate mounting threaded holes arranged in the have shown in Figures 31 to 33 embodiment the cover elements 88 on the front corresponding to this Push-through openings 93. In this context comes the internally open design of the guide rails 87 of such Fortification benefits. So that the pressure of the add-on elements is large can be recorded, the front of the cover is 88 with the front of the traverse 35 in one plane. Because e.g. at the installation of a hanging toilet bowl very large Bending moments are effective, the cover elements 88 are supported from the guide rails 87, making deflection very easy can be kept to a tolerable level.

But should it be necessary for heavy load reasons, the permissible deformation even with higher bending moments on one Limit certain amount can be used to further support the Traverse 35 and the connecting plate 84 a these parts supporting heavy-duty foot 94 (Fig. 1) can be provided on the floor space is mounted and at the back of the mentioned parts is attached and supports them. A support the cross member 35 can also have fastening tabs 20 take place, which are arranged accordingly. The construction and the operation of the mounting tabs 20 is from the above known.

In order to improve the guidance of the guide rail 87, a further traverse 35 with corresponding recesses 83 Pick up the guide rails 87 at the lower end of the vertical struts 3 be arranged.

The attachment of the truss 35, possibly using of sound decoupling elements is also already above described.

In Fig. 33 it can be seen that the fastening of the cover elements 88 on the connection plate 84 over in corresponding Receiving holes 103 insertable and bendable fastening tabs 104 takes place. This can also be done by working out the Spring tongue 85 openings are used. In particular this is the case when both the connection plate 84 and the Cover elements 88 made of sheet metal by means of a stamping and bending process are made. The spring tongues 85 with their spring lugs 86 are then simply punched out and bent on the Connection plate 84 arranged.

The cover element 88 (FIG. 1) or the connecting plate 84 (FIG. 32) have a holding opening 95 for holding and carrying out a Inlet pipe 96 from the cistern 45. For sound decoupling a ring, preferably made of rubber, sits in the holding opening 95 for sound-decoupled mounting of the inlet pipe 96. Furthermore, a holder 98 is provided, which is preferably made of plastic exists, and via a snap clip 99 onto the inlet pipe 96 can be snapped on. On the bracket 98 is still a detachable and attachable snap bracket 100 arranged through the one Drain pipe 101 can be attached to the bracket 98 in a sound-decoupled manner is.

For the sake of completeness, it should also be mentioned that the fastening threaded holes 96 in the connection plate 84 in the area of resilient tabs 102 are arranged so that the resilient Tab 102 by tightening the screws firmly against the Guide rails 87 are pulled and thus in addition to one secure positioning of the add-on elements. The springy Tabs 102 also take on the task of tolerance compensation, to bridge manufacturing deviations.

In addition, an embodiment is also quite realizable, in which an arrangement of all add-on elements on the Frame 2, be it over the trusses 35 or other elements, e.g. Cistern adapter 46, using Sound decoupling elements takes place. In addition, these can Elements also simultaneously the sound decoupling elements themselves represent. Such measures lead to a drastic reduction the noise development and thus ensure more well-being for the later user.

34 and 35, a truss variant is shown at which advantageously realizes sound decoupling has been. The cross member 35 has a cross member base body 105, in which numerous attachment options in the form of openings 106, 107 and 108 for attachment with a fluid components that can flow through are attachable. This traverse 35 can e.g. 5 and 6 can be seen for the attachment of fittings Find use. The struts 3 facing each End regions 109 of the cross member base body 105 are each with Plastic screws on a connecting piece 111 with an intermediate layer a damping element 112 attached. The connector 111 has a step-shaped cross section with essentially parallel end webs 113 and 114. The first end bridge 113 overlaps a region of the cross member base body 105 at a distance, so that the damping element 112 can be interposed. The Damping element 112 has corresponding openings for the Screw 110 on. At the second end web 114 are Fastening openings 115 provided that the pitch of the Longitudinal web 5 of the vertical struts 3 arranged perforated grid row are dimensionally adapted. Around the traverse 35 with the vertical struts 3 to connect, is still a locking plate, not shown used, which is arranged similar to the locking plate 41, so that the longitudinal web 5 of the vertical struts 3 between the second end web 114 and the locking plate. They don't locking plate shown preferably has at least one Latch that engages in a locking hole 36 accordingly. The Sound decoupling achieved by this truss variant highest requirement for permissible noise reduction requirements. In addition, the separate decoupling of each component is not mandatory, but can still be executed.

The various can be seen in particular with reference to FIG. 2 Installation options for pre-wall elements 1 with the help recognize the means described above. The most different Arrangement options for Sanitary installation in the room are due to this design given.
