Abstract

The connector has a connecting plate (61) with suitable openings (62) which coincide with guide openings (15) in the profiled strips (60) for connection by screw nuts. The openings (62) in the connecting plate are oblong holes (62) open towards the edge of same. Indentations (67) on the top side of the connecting plate are associated with protrusions on the underneath side of the plate to receive the nut. The connecting plate is made from sheet metal whereby the protrusions and indentations are formed together by a stamp. The height of the protrusions is less than the height of the guide opening (15). The protrusions and/or indentations can each be circular at the closed end of the openings (62)

Description

The invention relates to a connecting unit for connecting profile strips, according to the preamble of claim 1.

Such a connection unit is known from GB-A-558909, which deals with a Greenhouse construction deals. Here are the corners of the greenhouse by means of an angular connecting element, either outside or inside can be arranged on the rails, assembled. The connecting element has embossments in corresponding channels of the profile rail intervenes. At the same time, the screw heads or nuts of the screw connection are seated in these impressions and therefore do not survive.

In the prior art, profile strips with a length extending Guide opening used for a wide variety of uses. Frequently C profile rails are used as profile strips, e.g. also to establish one Light stand wall can be used. Since the profile strips accordingly are tailored to their use and an arrangement of the profile strips to each other at different angles, must be at the nodes Connection options are created so that the lightweight stand wall receives appropriate stability. Such profile strips can e.g. to bridge of empty spaces in the sanitary installation using pre-wall elements Find application. In general, as connecting means for the profile strips Knot plates are known, which bind several profile strips together, in whose guide openings are each fasteners that correspond with corresponding Openings in the gusset plates engage. However, it has shown during installation on site that the connection of the profile strips is relative has designed complex, since the more profile strips through the gusset plate with each other be connected, the alignment effort of the individual rails to each other considerably is. This even leads to the connection of several profile strips to one another so far that at least two installers had to do this work.

In US 34 15 554 a gusset plate is described by an embossing process is provided with depressions and opposing ridges. The circular elevations engage in corresponding openings to be connected Strive for. Furthermore, the gusset plate with at least one hole for one Provide fasteners.

Another connection unit is e.g. known from FR 21 41 012. This unity is used to connect C profile rails using countersunk screws and in the C-profile rails arranged nuts that are not within the rails can turn.

From FR 24 99 173 an element for connecting pipe profiles is known, the can have a recess at their ends. An increase in the tube profiles is inserted into this recess and a screw connects in this area the two parts.

In DE-B-1276315 there is a connection bracket for connecting C profile rails disclosed, which is arranged according to the guide openings of the C-profile rails, has elongated holes open to the edge.

A frame for a car body is known from EP-A-0136264. There will be two H-profiles joined together, one side of which is similar to a C-profile is. An angle serves as the connecting element, each on its legs has molded keys that fit into the corresponding openings in the profile rails fit in. Opposite the keys are groove-shaped Indentations in the legs, in each of which the head of a screw is arranged can be. For this purpose, there are corresponding openings in the connecting bracket brought in.

It is now the object of the present invention, a generic connection unit provide an easy to connect by Profile strips enabled and is easy and inexpensive to manufacture.

This object is achieved by the combination of the features of claim 1.

The elevation on the connecting plate serves as a guide for the profile strips, since they are inserted into their guide openings essentially with a precise fit. It it is obvious that even when using two elevations for a profile bar whose position can only be changed in a spatial axis direction can. In the case of profile strips cut off at right angles, it is even the case that it is mostly is sufficient if a profile bar by a single increase and by investing the Face of the profile bar aligned with the side surface of another profile bar becomes. This also ensures that the side surfaces of certain profile strips can automatically form the stop surfaces for other profile strips, so that their position is clearly defined among themselves. This reduces the installation effort is considerable since the installer only has the profile strips by plugging the guide openings onto the ridges and tightening the Fasteners must connect. A subsequent alignment can largely eliminated.

Have the indentations opposite the elevations on the connecting plate the enormous advantage that by slightly tightening the nuts on the screws, the elevations are already well in the guide openings of the profile strips are positioned, but it is still possible to move the profile strips without that the screw-nut elements change their position, relative to the connecting plate. This brings an enormous simplification to the handling of the connection unit with itself, since the screw-nut elements are not accidentally in the Can move the elongated hole during an adjustment process. The installer So there is no need to pay attention to that. Furthermore, one can Embossing process Elevations and depressions at the same time at one point on the connecting plate produce. This makes a simple manufacturing process of increasing and deepening. The openings are as to the edge of the connecting plate open slots are formed, the on the bottom of the Connection plate arranged elevation on the top of the plate recesses assigned to an area of the mother. Preferably you can Point all open ends of the elongated holes of a connecting plate away from each other. The oblong holes open on one side favor the insertion of one into the profile strip located screw, so that this is not cumbersome by a closed Opening in the connecting plate and then in the guide opening of the Profile bar must be inserted.

The ridges and / or depressions are each at the closed end of the Openings are essentially circular. A circular shape ensures that the profile strips can be plugged onto the ridges at different angles are. The circular shape of the depressions, on the other hand, prevents them from moving the mother in the slot, but at the same time ensures that the mother can be tightened further.

Conveniently, the screws can be semicircular screws with a square socket, whose square can be inserted non-rotatably into the openings of the connecting plate. This configuration offers the advantage that when the button head screw is once in the guide opening the profile strip is inserted, this in the guide opening is held against rotation, so that the installer no additional tools needed to counter the screw head To secure rotation.

So that the mother is positioned essentially in the recess it can have a cylindrical guide projection, which essentially fits snugly into the recess can be used.

In particular when connecting thin-walled profile strips and Insert thin-walled connecting plates with standard round head screws can, the mother can add a hole, especially for Have the square of the button head screw. Hereby ensures that regardless of the thickness of the connecting plate and the profile bar a corresponding standard round-head screw to provide the twist lock of the screw in the Guide opening of the profile bar is provided.

As a rule, the profile strips can preferably be C-profile rails be by the enlarged head of the semicircular screw are clamped against the connecting plate. C profile rails find widespread use, which is why they are relatively inexpensive can be obtained. In addition, there are commercially available Dimensions enforced in such C-profile rails.

Since usually the profile strips for erecting a lightweight stand wall run perpendicular to each other, it is in another Embodiment favorable if the openings including the Deepening and raising in two or three perpendicular to each other Rows are arranged. By the appropriately designed Connection unit can thus be vertical very quickly Make connections in one level or three-dimensionally.

To also have several C profile rails in parallel alignment with each other To be able to connect, it is in a further embodiment advantageous if the parallel distance from the center of the depression and increase accordingly among themselves in a row of openings essentially the sum of half the widths of the to be joined Corresponds to C rails. This measure also ensures that C profile rails of different widths with each other can be connected. The increases and decreases are then arranged accordingly in the connecting plates.

Another variant is one with the connecting plate provide connectable connecting bracket, which is also correspondingly spaced elevations arranged around openings has, of which at least two each on an angle leg are arranged and fit snugly in the recesses of the connecting plate are insertable. This allows for easy Way a spatial arrangement of z. B. Realize C rails, the alignment of the C-profile rails due to each other the angle given by the connection angle and the Allocation of elevations on the angled legs and depressions takes place automatically in the connecting plate.

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 for WC installation and Figures 5 and 6 a corresponding pretext element for attaching a washbasin and fittings. On the individual configuration is discussed in more detail below. But there are also other conceptions of pretext elements, especially regarding the extensions, conceivable, the are adapted to the various 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 an open Hollow profile, preferably a C-profile, formed the vertical struts 3 spaced cross strut 4. How 7, the hollow profile is made the vertical struts 3 from a roll-formed box profile, preferred rectangular cross-section, with a one-sided on it, in the Longitudinal web 5 arranged in the middle of a shorter transverse side thereof. The longitudinal web 5 has three times the material thickness of the rest Hollow profile, since it is bent by bending one end of the sheet over the other sheet metal end was produced. Preferred is the material galvanized sheet steel is used, which paints before profiling or coated with a colored film.

The C-profile of the cross strut 4 and the box profile of the vertical struts 3 preferably have the same in this exemplary embodiment Opening cross-section on the inside. The respective end openings 6 and 7 of vertical strut 3 and cross strut 4 serve as Sockets 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 offset by 90 ° to each other arranged so that the corner connector 8 receives an L-shape and the plug-in lugs 9, 10 represent the L-legs. 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 area 11 is preferably the Adjusted outer contour of vertical struts 3 and cross strut 4 or stands over this. This configuration makes stop surfaces 12 formed on which the perpendicular to their longitudinal axis Attach the cut vertical struts 3 and cross strut 4 flat can. When connecting the struts 3, 4 using the corner connector 8 is therefore automatically a high dimensional accuracy manufactured.

Furthermore, each plug insert 9, 10 has a transverse to the respective Threading direction extending threaded bore 13, 14 on, in the suitable screws for fastening to the struts 3, 4 can be screwed in are. With the cross strut 4, this can be done parallel to whose longitudinal extension arranged guide opening 15 used become. For this purpose, the vertical strut 3 can have a corresponding opening 16 have. The attachment e.g. on the vertical strut 3, can also be done in such a way that a countersunk screw in the threaded bore 13 is used, which does not have the outer surface of the Plug projection 9 protrudes, and the opening 16 has a diameter which is smaller than the head of the screw used, but is large enough to be accessed by a tool Ensure screw head. The screw head can then against the inner wall of the vertical strut 3 when the corner connector is inserted 8 be braced. In this embodiment, the Attachment of the corner connector 8 to the struts 3 also from the Front of the frame 2 take place as the fasteners do not survive.

In Figures 8 and 9 it can be seen that the corner connector 8 with its plug inserts 9, 10 also as e.g. Die-cast aluminum or plastic injection molded part, and can be made corresponding stiffening ribs and cavities 17 may have to avoid material accumulation.

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

According to another variant according to Fig. 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 19 axially in the Through hole secures. The screw 19 is then rotatable in the Corner connector 8 held. The main supporting force is from the on the thread of the screw 19 screwed nut 19c and washer 19d, which are supported against the vertical strut 3, transfer.

Furthermore, it can be seen from FIG. 8 that the fastening tab 20 also as e.g. Die-cast aluminum element or plastic element can be executed. 8 is also closed recognize that on the back of the mounting bracket 20 a hook element 23 from the rest of the support surface of the mounting bracket 20 is arranged set back. The hook element 23 is in the Position in a corresponding guide opening on a mounting wall attached C-profile rail. Thereby the assembly of the pre-wall elements 1 can be greatly simplified. If necessary, attaching to a bore 24 a C profile rail. 9 is still closed recognize that the mounting tab 20 also several elongated holes 22nd can have to the number of different mounting options to increase. Since the mounting tab 20 around the Pivot axis on the central area 11 of the corner connector 8 can be pivoted is, it can be in various positions on the mounting wall be attached.

The end region 25 of the fastening tab arranged around the threaded sleeve 21 20 has a rounding concentric to the pivot axis with a radius that is essentially the shortest distance A the pivot axis on the corner connector 8 to the outer edge or corresponds to the upper edge of the cross strut 4. This ensures that the top edge of the end portion 25 and the top of the corner connector 8 together in one to the front of the Frame 2 vertical plane lies. This is particularly advantageous if the top of the pre-wall element 1 as a support for a shelf arranged on it is to be used. This elements forming the shelf, e.g. a gypsum fiber cement or Plasterboard, then lie in the wall area on the support areas of the end regions 25 and are automatically in the corresponding Angle aligned to the front of the pre-wall element 1.

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. By simply plugging them together These components are both stable and extremely precise design of the frame 2 possible, so that a string of several wall elements 1 due to the high Dimensional accuracy is far less problematic than when standing of the technique. In addition, the attachment of the pre-wall elements by the pivotable attached to the corner connectors 8 Mounting tabs 20 very simplified. Completeness half of it should be mentioned that the attachment of such fastening tabs 20 also at other points of the pretext element 1 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 essentially precisely fitting guide rails 26 serve that telescopic in the vertical struts 3 are supported. The guide rails 26 are perpendicular to Longitudinal extension of a lower cross strut or bottom bar 27 is arranged and attached to it. In the illustrated in the figures Embodiment are used as guide rails 26 C-profile rails used. The bottom bar 27 has not shown Fastening openings for attaching to the floor or one attached to this C-profile rail. At the lower end the vertical struts 3 also have an opening 16, through which a screw 28 can be inserted. Inside the vertical struts a specially designed clamping nut has been introduced, in which there is a threaded bore 30 for screwing in the Screw 28 is located. The lock nut 29 is thus inside the held lower end region of the vertical struts 3. The clamping nut 29 looks approximately V-shaped in cross section, so that essentially two clamping legs 31 are formed. At one end of the lock nut 29 there is a pin 32 on which a bow spring 33 with its Middle area is pressed. The bow spring 33 has two spring arms 34 on, the deflection transverse to the direction of insertion of the guide rails 26 takes place.

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 opposite the vertical strut 3. The bow spring 33 now has the Purpose that the spring arms 34 already in the released state of the clamping nut 29 a spring force on the side areas of the guide rails 26 exercise. This spring force is preferably chosen so that the entire pretext element 1 by loosening the screws 28 not automatically adjusted, but held in its position becomes. A displacement of the guide rails 26 in the vertical struts 3 can only after applying a separate displacement force take place, which gives the installer enormous advantages the assembly of the pre-wall elements 1 because he does not hold in a certain telescopic position. By Tightening the screws 28 then the position or the exact height of the pre-wall element 1 fixed. Through the adjustment range created in this way can with a pretext element 1 the flexibility regarding the mounting at different heights is greatly expanded become. The installer is not at certain wall element heights bound and can be according to customer requirements adjust this. At this point it should also be mentioned that the clamping nut 29 is also e.g. Die-cast aluminum or plastic injection molded part with a correspondingly curved Leaf spring can be, and here the clamping nut 29 can be corresponding Ribs and cavities to avoid material accumulation exhibit.

The configuration described above with the telescopic guide rails 26 also has the advantage that at wall-high Upgrading two or more pretext elements can be that provided with the guide rails 26 End of the vertical struts 3 point away from each other, so that in the one wall element, the bottom bar 27 is now at the top and can be connected to the ceiling of the room (see see also Fig. 2 right side). Let through this configuration deviations in the room heights are easily caused by the corresponding Displacement of the guide rail 26 in the vertical struts 3 realize.

It can be seen from FIGS. 1, 3, 5 and 13 that the pretext element 1 several are essentially parallel to the cross strut 4 extending trusses 35 which with the vertical struts 3 are firmly connected and essentially for holding and arranging of attachments. As already mentioned above, the Vertical struts 3 a extending in their longitudinal extent Longitudinal web 5, which is three times the wall thickness of the rest of the profile has (see also Fig. 14 and Fig. 15). The triple Wall thickness of the longitudinal web 5 gives it a particularly high Strength and the vertical strut 3 sufficient rigidity. Of furthermore, the longitudinal web 5 also has a along the longitudinal extent the vertical strut with 3 rows of perforations square locking holes 36. The locking holes 36 two a common Vertical struts 3 forming frame 2 each rest same height. The center distance between two locking holes 36 is preferred chosen very small in order to take as many pictures as possible on the longitudinal web 5 to provide. In one embodiment, the center distance is about 1 cm.

The cross member 35 consists essentially of a U-shaped curve Sheet metal, each with latches at its ends 37 is formed, which each engage in the locking holes 36. For this purpose, the U-web of the is in the end regions of the cross member 35 U legs 39 released and parallel by a step 38 inwards offset so that an approximately H-shaped profile at the end regions arises. The U-legs 39 are stamped, see above that the locking lugs 37 and recesses 40 are formed. The dimension the recess 40 is chosen so that its depth is less than the thickness of the longitudinal web 5, but the width of the front Take up the area of the longitudinal web 5 with the detent 37 attached can. The end region of the cross member 35 is a locking plate 41 assigned with a screw 42. The locking plate 41 is supported when the locking lugs 37 are inserted into the locking holes 36 on the support surface 43 of the U-leg offset to the rear 39, while the screw 42 in the threaded bore 44th is screwed into the end region of the cross member 35. This will the locking lugs 37 firmly drawn into the locking holes 36 during the base of the cutouts 40 is supported on the longitudinal web 5. On this way the trusses depending on the Arrange the hole pattern at any height of the frame 2, what by simply inserting the locking lugs 37 into the locking holes 36 and tightening the screw 42 with the locking plate 41. In In this context it should also be mentioned that, for simplification marking strips corresponding to the installation on the vertical struts or stickers can be arranged that the respective Position for attaching a specific traverse, e.g. Toilet or shower crossbar, Show.

Furthermore, it should be mentioned in advance that one designed in this way Traverse 35 by only minor modifications for numerous cultivation purposes can be used. 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 attachment elements attached to the crossbeams and how they work is provided.

With reference to Figures 1, 3, 4 and 16 to 19 it can be seen that to attach one between the two vertical struts 3 arranged cistern 45 on both sides a corresponding molded cistern adapter 46 is used. The cistern adapter 46 has the advantage that it is the most diverse Cisterns 45 on the row of perforations of the longitudinal web 5 enables. The cistern adapter 46 preferably consists of the cistern 45 made of plastic and can therefore be used the injection molding technology can be carried out very simply in one piece. The Cistern adapter 46 has a base plate 47 for attaching a corresponding flange strip 48 on the cistern 45. The base plate 47 is with essentially T-shaped hook elements 49 provided in the corresponding openings 50 on the flange 48 intervene in order to be able to reach behind the flange strip 48. So that the hook elements 49 are not unintentionally disengaged, are U-shaped recesses 51 in addition to the hook elements introduced so that resilient pressing lugs 52 are formed, the intervene correspondingly functionally on the flange strip 48. On the base plate 47 close on one long side two right-angled leg 53, 54 in Rows. The angle legs 53, 54 have in common, as in particular is also seen in Fig. 16, also a substantially U-shaped Recess 55, which on the vertical angle leg 53 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 parallel angle leg 54 are truncated pyramid-shaped Locking pin 59 arranged, their size and distance is selected to each other so that they in the locking holes 36th are inserted 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 locking element 57 essentially the same size as the thickness of the longitudinal web 5. This is particularly nice to see in Fig. 20. By the Cistern adapter 46 can now be easily commercially available Cisterns easily on vertical struts 3 of pre-wall elements 1, which have a hole pattern. The The cistern adapter 46 is also detached from the longitudinal web 5 very simple, since the locking elements 57 both for removing, as also have corresponding bevels for plugging in. On Another advantage of the plastic cistern adapter 46 is that it is also a sound decoupling element serves.

With the help of FIGS. 2 and 21 to 26, the following are connection variants of open hollow profiles, especially 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 of an assembly wall are also to be bridged over but still of gypsum fiber cement arranged on the pre-wall elements or plasterboard, which are then covered preferably tiled. To be sufficient for these items To ensure support are between the individual pretext elements 1 connecting struts 60, preferably in the form of C profile rails arranged. To the installer installing this To facilitate connection struts 60 becomes a suitable connection unit provided, consisting essentially of a connecting plate 61, the openings 62 in the form of to the edge of the connecting plate Has 61 oblong holes open, and accordingly in the opening 62 insertable screws 63, preferred Half-round screws with square shoulder, with associated nuts 64 consists. The openings 62 have one at their closed end approximately circular impression 65, so that on one Side of the connecting plate 61 ridges 66 and on the other A correspondingly assigned depression 67 is formed on the side. The diameter D of the elevation 66 is such that it essentially the width of the guide opening 15 one to be connected C-profile rail corresponds. The height of the increase E is such that that this is equal to or less than the wall thickness of the Connecting strut 60. The height E is preferably only slightly lower. The semicircular screw 63 used for this purpose has a lenticular head 68, the diameter of which is larger than the width of the guide opening 15 of the connecting strut 16. Therefore, the free end areas that the guide opening Limit 15 of the connecting strut 60 when the screw is loosened 63 between the bottom of the head 68 and the connecting plate 61 insert. The connecting strut 60 is thereby increased 66 guided essentially in register. The half-round screw 63 has a square section 69 below its head 68, which can be slidably inserted into the opening 62 in the connecting plate 61 is, but can not turn in this. The hex nut 64 has on its facing the connecting plate 61 End a guide lug 70, which fits in substantially the recess 67 can be used. From this configuration results now that the connection of the connecting plate 61 with a Connection strut 60 very simple under certain circumstances even with only one hand is possible.

If a commercially available half-round screw 63 is used, can the nut 64, as in the embodiment shown in FIG. 22 a bore extension 71 to accommodate the area of the Have square section 69. Accordingly, similar Connecting struts 60 can be connected to one another the parallel distance C of the center of the recesses 67 and Increases 66 corresponding to one another essentially in width G of the connecting strut 60. Furthermore, the openings 62 including the recesses 67 and ridges 66 in two vertically arranged rows arranged to each other. In the shown For example, there are three openings 62 and in one row the other row two openings 62. The connecting plate 61 is for this reason it has an approximately triangular shape since the series with the two openings 62 perpendicular to the middle of the row the three openings 63, so that their central opening 62nd belongs to the other row at the same time. The open sides of the Accordingly, openings 62 all point away from one another. The connection unit can also be used to connect different profile strips be used, whereby the dimensions concerned accordingly have to change.

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 Connecting strut 60 are attached. Because the increases 66 arranged accordingly in the associated guide openings 15 are guided, the two rows of openings are automatic arranged parallel and perpendicular to the continuous connecting struts 60. Moving the connecting plate 61 along the Guide opening 17 is very loosened screw 23 and nut 64 simply possible. Since the connecting struts 60 are usually accurate can be cut perpendicular to their longitudinal extent the end faces of the two with the continuous connecting strut 60 connecting struts 60 to be connected to this, with an additional increase 66 of the connecting plate 61 are performed. This fact makes the alignment work the connection struts to each other extremely easy.

24 shows a connection point at which two connecting struts 60 perpendicular to one another get connected. The drawing clearly shows that the connecting plate 61 has a triangular shape with two has legs of equal length that enclose a 90 ° angle. Accordingly, the third leg runs to the two first under 45 °. Each assigned to the tips of the triangular shape Wells and ridges 66 are seen in series, respectively arranged parallel to the legs, so that automatically one right-angled fastening, as shown in FIG. 24, is achievable. Furthermore, the diameter of the depression is 67 chosen 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 not heard half the width of the connecting strut 60 corresponds to. This can increase the outside struts 60 is used for management purposes. Furthermore, this type of attachment shows that only two Screws 63 and nuts 64 are necessary to ensure a stable attachment ensure.

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 connecting connecting struts 60 also in two mutually transverse planes can take place, an area 72 of the connecting plate 61 from the Base plane of the remaining connecting plate 61 is bent through 90 °, that the resulting recess 73 essentially the outer dimensions of a connecting strut 60 to be connected corresponds. The area 72 also has an opening 62 corresponding increase 66 and depression 67, which continues to at least one opening 62 in the base plane of the connecting plate 61, even if offset by 90 °, aligned in line is. This allows e.g. a vertically continuous connecting strut 60 with two connecting struts ending at this 60 connect with each other without the need for a large alignment effort required, since the two adjacent connecting struts automatically through the connecting plate 61 in one plane on the continuous connecting strut 60 are attached.

In the variant according to FIGS. 26a and 26b, one is with the connecting plate 61 connectable connecting bracket 161 is provided, the corresponding to the connection plate 61 impressions 65 to provide of elevations 66 and depressions 67 in its angle legs having. The angle between the angle legs is preferably 90 °, so that a suitable spatial arrangement of C profile rails 60 can take place. So that an exact positioning is made automatically, each have two assigned Increases 66 on the connection angle 161 one size and one Distance in such a way that they are in corresponding recesses 67 can be used in the connecting plate 61 with a precise fit. The distance from the protruding angle leg, which is inserted by the Elevations 66 on the other angle leg in its spatial Alignment with the connection 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 pretext element given is.

The connecting plate 61 is preferably produced from sheet metal and the elevation 66 and the depression 67 accordingly made by embossing 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 the operation of a support angle described, the same time can also be used as a connecting element. The support angle 74 has a substantially flat contact surface 75 and a mounting surface 76 and a support surface 77. The attachment and support surface 76, 77 are 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 of the attachment opening 78 is from the support surface 75 directed away. The center distance L of the two mounting holes 78 each of the fastening and support surface 76, 77 corresponds to the width G through the support angle 74 connecting C-profile, which a connecting strut 60 or a cross strut 4, based on pretext elements 1, can be. Of the vertical distance M from the support surface also corresponds 75 to the axis of those later inserted into the fastening openings 78 Screws 79 essentially half the C-profile width G / 2. This means that e.g. guaranteed to a cross strut 4, that the bearing surface 75 in one plane with the top 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 appropriate Arrangement of the support angle a number of connection options surrender. Furthermore, the support bracket 74 can be very good for support and attaching cover elements to be attached to the pre-wall element 1, e.g. Gypsum fiber cement or plasterboard used become.

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 that of the width of the guide opening 16 of a C-profile rail 4, 60 corresponds. The axis of symmetry also points of the two rows a distance M from the contact surface 75 on, which corresponds essentially to half the C-profile width G / 2. The knobs 80 are used to guide and align the support angle 74 in the guide opening 15 of a C-profile rail 4, 60 the support bracket 74 can be very easily on a C-profile rail 4, 60 align and using the screw 79 and nut 81 connect to the C-profile rails 4, 60.

The contact 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, in the respective mounting holes 78 located fasteners 79, 81. Also serves the access opening 82 as a fastening opening in the stud wall and overhead installation. For the sake of completeness, that in the support surface 75, as can be seen in Fig. 28, fastening openings and knobs can be arranged, but not mandatory the dimensions of the fastening openings 78 on the fastening and support surface 76, 77 must follow. The fastening and support surface 76, 77 each have bores 76a, 77a on that for attachment, especially by means of self-tapping Screws on a lightweight stand wall.

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. On the one hand, it serves as a support surface on a pretext element 1 and on the other hand he can for numerous different connection variants of C-profile rails 4, 60 can be used.

In the following, one is used with reference to FIGS. 1 to 4 and 31 to 33 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. Furthermore the crossmember 35 has recesses 83 in its U-legs 39 on. A connection plate 84 rests on both U-legs 39, which is connected to it by means of screws. The connection plate 84 protrudes downward over the cross member 35 and has approximately one T-shaped shape. The upper crossbar of the T-shape covers the crossbar 35 on their 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 a spring nose 86 at its end region facing away from the fixed end on that towards the crosshead 35 over the rest of the surface the connection plate 84 protrudes. The spring nose 86 is located in the area of the recess 83 or, as in the exemplary embodiment shown, just below these. The recesses 83 form a guide receptacle, which is covered by the connecting plate 84 is, for slidably receiving guide rails 87. It are two guide rails 87 on one for each wall element 1 Bottom rail 27 arranged and fastened with this. The guide rails 87 extend parallel to the vertical struts 3 above and have a width and thickness that result in a substantially precisely fitting receptacle in the recesses 83 or the guide receptacle leads. As material for the guide rails 87 preferably a U-shaped flat steel used to at the same time one rigid in the direction of loading, but still relative easy to achieve. On the connection plate 84 are in Extension of the guide receptacles leading cover elements 88 arranged. On the one hand, this can, as shown in FIG. 1, by a plate attached to the cross member 35 or connecting plate 84, or, as shown in Fig. 31, by two essentially U-shaped sheets are made. Which are in the leadership shots Guide rails 87 are located by the spring lugs 86, such as can be seen in Fig. 33, applied with a spring force, so that the displacement of 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 looks out. The anchor device consists essentially of one in extension of the vertical struts 3 from these by means of a associated adjusting nut 89 screwed in and out Threaded rod 90. This is in the lower end of the vertical strut 3 each have a plug 91 fixedly arranged for it to pass through the threaded rod 90 allows, but a support for the Represents adjusting nuts 89. The plug 91 can over a Support the collar on the face of the vertical struts 3 or is connected to this via other fasteners. The lower The end of the threaded rod 90 is supported on the bottom bar 27. The adjusting nut 89 is for quick adjustment as a tilt nut trained so that the installer as quickly as possible can make an adjustment. 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 connection 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 in 31 to 33 shown embodiment the cover elements 88 on the front corresponding to this Push-through openings 93. In this context comes the internally open configuration of the guide rails 87 of such a fastening benefit. 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 become effective, the cover elements 88 are based on the Guide rails 87 from, causing a deflection very easily a tolerable level can be kept.

Should it be necessary for heavy load reasons, the permissible Deformation even at higher bending moments to a certain one Limiting amount can be used to further support the traverse 35 or the connecting plate 84 a supporting these parts Heavy duty foot 94 (Fig. 1) may be provided on the floor space is mounted and on the back of the parts mentioned is attached and supports it. Supporting the traverse 35 but can also be done via mounting tabs 20, the corresponding be arranged on it. The structure and how it works the mounting tabs 20 is known from the above.

In order to improve the guidance of the guide rail 87, another can Traverse 35 with corresponding recesses 83 for receiving the guide rails 87 at the lower end region 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 via in corresponding receiving holes 103 insertable and bendable fastening tabs 104. This can also be done by working out the spring tongue 85 openings are created. In particular is 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. The spring tongues 85 with their spring lugs 86 are then by simply punching out and bending 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, and can be snapped onto the inlet pipe 96 via a snap clamp 99 is. On the bracket 98 is a detachable and pluggable locking bracket 100 is arranged through which a drain pipe 101 soundproof is attachable to the bracket 98.

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 be pulled and thus in addition to a safe positioning of the add-on elements. Take over the resilient tabs 102 also the task of tolerance compensation to avoid manufacturing deviations to bridge.

In addition, an embodiment is also entirely feasible, in which an arrangement of all add-on elements on the frame 2, be it over the truss 35 or other elements, e.g. Cistern adapter 46, using sound decoupling elements he follows. In addition, these elements can also be used simultaneously Represent sound decoupling elements themselves. Such measures lead to a drastic reduction in noise 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 fastening a fluid through which fluid can flow Components are attachable. This traverse 35 can e.g. as in 5 and 6 can be seen for the attachment of fittings use Find. The respective end regions 109 of the struts 3 Truss base body 105 are each with plastic screws a connector 111 with the interposition of a damping element 112 attached. The connecting piece 111 has a step-shaped Cross section with substantially parallel end webs 113 and 114 on. The first end web 113 overlaps an area of the Truss body 105 at a distance, so that the damping element 112 can be inserted. The damping element 112 has corresponding openings for the screws 110. At the second terminal 114 mounting holes 115 are provided, the grid size arranged in the longitudinal web 5 of the vertical struts 3 Hole grid row are dimensionally adapted. To the traverse 35 with the To connect vertical struts 3, is not shown Locking plate used, which is arranged similar to the locking plate 41 is so that the longitudinal web 5 of the vertical struts 3rd is located between the second end web 114 and the locking plate. The locking plate, not shown, preferably has at least a locking lug which engages accordingly in a locking hole 36. The sound decoupling achieved by this truss variant is fulfilled highest requirement for permissible noise reduction requirements. In addition, the separate decoupling of each component not mandatory, but can still run become.

The various mounting options can be seen in particular with reference to FIG. 2 of pretext elements 1 with the help of the above recognize described means. The most diverse arrangement options for plumbing in the room are through this Given design.
