Description

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting unit for connecting profile rails having a guide slot extending in the longitudinal direction at least in the connecting region, the connecting unit comprising a connecting plate with respective notches and connecting elements formed by bolts and nuts which are inserted into the notches. and guide slots for securing the connecting plate to the profile rails.

Background Art

Profile rails with a guide slot extending over their entire length are used for a variety of purposes. Profile rails often use C-shaped section rails, which are used to create lightweight load-bearing walls. Since the profile rails are cut to the required length for a given application and the profile rails are arranged at different angles or angles to each other, connection possibilities must be provided at the nodal points to ensure that the lightweight support wall will have sufficient stability. Such profile rails can be used, for example, to bridge empty spaces by means of front wall panels intended to house an ambulance. In general, gusset plates are used as connecting means for the profile rails, which simultaneously connect several profile rails to each other, in which connection elements there are always fastening elements which engage the respective openings or notches through which the gusset plates are provided. However, during the installation it has been shown that the connection of the profile rails is relatively complicated in construction, since the more profile rails to be connected to each other by the gusset plate, the more difficult it is to arrange the individual rails relative to one another. This fact leads to the fact that several profile rails are connected to each other even by at least two plumbers.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a connection unit by means of which the connection of profile sheets can be carried out simply.

SUMMARY OF THE INVENTION

This object is achieved by a connecting unit for connecting profile rails, which at least in the connecting area is provided with a guide notch extending in the longitudinal direction, wherein the connecting unit consists of a connecting plate with respective notches and of connecting elements formed by bolts and nuts which are inserted into the notches and guiding notches for securing the joining plate to the profile rails, according to the invention, wherein at least one elevation is provided at least around a portion of the notches adapted to the light width of the guiding notches, wherein the notches in the joining plate are arranged relative to the desired joining angles of the profile rails .

*

The elevations provided on the joining plate serve essentially as quasi-profile rails, since the elevations are substantially aligned in the respective guide slots. Obviously, even when using two elevations for one profile rail, its position can only change in one spatial direction. When the profile rails are cut or cut perpendicular to their longitudinal direction, it is usually sufficient if the profile rail is precisely aligned with only one elevation and by placing its front side on the side surface of the second profile rail. This also ensures that the faces of certain profile rails can automatically form stop surfaces for other profile rails, so that their position with respect to each other is clearly defined. This greatly reduces the complexity of the assembly, since the installer has to connect the profile rails to each other only by inserting guide notches for elevation and tightening the fasteners. Subsequent alignment of the profile rails is virtually eliminated.

According to a preferred embodiment, the elevations may have a height which is less than the height of the guide notch. This ensures that even the simplest standard screws can be used for the fastening, since both the screw head and the nuts of the respective fasteners can bear flat on the respective elements when fastening without the need for precautions on the bearing nut. elevation.

According to a further preferred embodiment, the notches are formed as longitudinal slots open to the edge of the connecting plate, whereby a recess is assigned to the upper side of the connecting plate for receiving a portion of the nut by an elevation arranged on the lower side of the connecting plate. Preferably, all open ends of the longitudinal notches of the coupling plate may be facing away from each other. The notches open on one side allow the screw located in the profile rail to be inserted so that the screw does not need to be uncomfortably passed through the closed opening in the connecting plate and then inserted into the guide notch of the profile rail. The recesses opposite to the elevations in the joining plate have the special advantage that by slightly tightening the nuts on the bolts, the elevations are already better positioned in the guide rails of the profile rails, but still the profile rails can be moved without the connecting elements formed by bolts and nuts they changed their position relative to the coupling plate. This brings about an enormous simplification of handling of the coupling unit, since the connecting elements formed by bolts and nuts cannot extend out of the longitudinal guide notch during alignment. Therefore, the installer may not pay attention to this fact.

According to a further preferred embodiment, the elevations and / or depressions are each formed at the closed end of the notches in a substantially circular shape. The circular shape ensures that the profile rails can be mounted on elevations under a variety of inclinations. By contrast, the circular shape of the recess prevents the nut from sliding in the longitudinal guide notch, but at the same time ensures that the nut can be further tightened.

According to a further preferred embodiment, the screws may be so-called half-head door bolts, below which a square is provided, the square being inserted non-rotatably into the notch in the connecting plate. This embodiment has the advantage that when the round head bolt is once inserted into the guide slot of the profile rail, it is held in this guide notch so that the installer does not need any additional tool to secure the bolt head against rotation.

In order to insert the nut into the recess substantially flush, the nut can be provided with a cylindrical guide piece which is inserted into the recess substantially flush.

In order to use standard bolts with a round head when connecting thin-walled profiled bars and thin-walled joining plates, the nut may be provided with a recess, in particular for receiving a square under the half-head of the bolt. This ensures that, irrespective of the thickness of the connecting plate and the profiled strip, a suitable standardized half-head bolt can be used for their connection, which is locked non-rotatably in the guide notch of the profile strip.

In all cases, the profile rails can preferably be designed as C-shaped profile rails, which are clamped to the connecting plate by means of a bolt-shaped screw head. C-shaped section rails are advantageous because they are relatively inexpensive. In addition, these C-shaped profile rails have standard dimensions.

Since, as a rule, they are generally perpendicular to each other to form a lightweight profile bar support wall, it is preferred according to a further embodiment of the invention that the notches in the connecting plates, including the recesses and elevations, are arranged in two or three mutually perpendicular rows. It is therefore possible to create very quickly both perpendicular connections in one plane and three-dimensional connections in such a suitably designed connection unit.

In order to be able to connect several C-shaped cross-sections to each other in parallel with each other, according to a further embodiment of the invention, it is advantageous if the distance between the centers of the recesses and the elevations in one row of cuts corresponds substantially to the sum of the half-widths of the C-shaped profile rails to be joined. that the C-shaped section rails of different widths can be connected to one another. Then, elevations and depressions in the connecting plates are respectively arranged.

t

A simple method of producing elevations and depressions in the joining plate is, according to a further variant, in that the joining plate is made of sheet metal, and then the stamping of the sheet together creates a raised and recessed one. It is therefore possible to simultaneously create elevations and depressions in the joining plate by a single indentation.

Another variant is that the connecting plate is provided with an attachable connecting bracket, which is also provided with elevations provided at a distance from one another and arranged around the fixing slots, each of which at least two are arranged in the arm of the connecting angle and can be inserted into the recess in the connection circuit board. For this purpose, a spatial arrangement of, for example, C-shaped section rails can be carried out in a simple manner, whereby alignment of the C-shaped section rails with respect to each other is automatically performed with respect to a predetermined angle given by the connecting angle and relative alignment of the elevations on the connecting angle arms. and a recess in the coupling plate.

EXAMPLES OF THE INVENTION

The front wall panel 1 used for the sanitary installation can be modified in various ways for various applications, as shown, for example, in Figures 1, 3 and 4, where the WC front panel 1 is shown, and in Figures 5 and 6, where there is shown a front wall panel 1 for fixing a washbasin and fittings. The individual embodiments will be described in more detail below. However, there are also completely different front wall concepts, especially for superstructures that are adapted to different applications, such as showers, bathtubs, urinals, bathroom furniture, etc.

The front wall element 1 consists of a frame 2 made up of two vertical struts 3 made of hollow profiles and a transverse strut 6 made of an open hollow profile, in particular of the profile C, which holds the vertical struts 3 apart from one another. In particular, as shown in FIG. 7, the hollow profile of the vertical struts 3 is in particular a box profile made by bending, in particular a rectangular cross section, with a longitudinal web 5 disposed in the middle of the shorter side of the cross-section. The longitudinal web 5 has three times the thickness of the other portions of the hollow profile since it is formed by bending one end of the sheet over the other. Preferably, the material used is a galvanized steel sheet which is coated with a lacquer or coated with a colored film prior to profiling.

The profile C of the transverse strut 4 and the box profile of the vertical struts 2 preferably have the same inner cross-sectional area in this embodiment. The respective end openings 6 and 7 of the upright strut 2 and the transverse strut 4 serve as plug-in bearings for the corner plug connector 8, which, with its plug-in extensions 9 and 10, extends substantially into the end openings 6 and 7. 9, 10 are arranged at 90 'to each other so that the corner plug connector 2 is L-shaped, the arms of which are plug-in inserts 9, 10. The corner plug connectors 8 form at least the upper corners of the frame 2. visible corner. For this purpose, the central portion 11 is preferably adapted to the outer contour of the vertical struts 2 ^and transverse strut 4. By this embodiment, the abutment surfaces 12 are formed on which the vertical struts 2 ^and the transverse strut 4, which is cut perpendicular to its longitudinal axis, abut. Therefore, dimensional accuracy is automatically maintained when the struts 3, 4 are assembled by the corner plug connector 8.

Furthermore, each plug-in adapter 9, 10 is provided with a threaded hole 13, 14 provided perpendicularly to the insertion direction, in which a suitable screw is always screwed in to fasten to the struts 3, 4. In this case, a guide notch may be provided for the transverse strut 4. 15, executed parallel to its longitudinal axis. The vertical strut 2 may be provided with an opening 16 for this purpose. The fastening, for example, on a vertical strut 2 may also be carried out by screwing a countersunk head screw which does not protrude above the outer surface of the male extension 9 into the threaded hole 13 and the opening 16 has a diameter that is less than the head of the screw used, but large enough to provide access to the tool head of the screw. The screw head can then be pressed against the inner wall of the vertical strut 2 with the plug-in connector 8 inserted, by unscrewing the screw. In this embodiment, the attachment of the corner plug connector 8 on the vertical struts 2 can also be performed from the front side of the frame 2 as the fastening means do not protrude.

FIGS. 8 and 9 show that the corner plug connector 2 can be provided with its plug-in adapters 9, 10 as an aluminum die-cast part or as an injection-molded plastic part and can therefore be provided with suitable reinforcing ribs and cavities. 17 to prevent material buildup.

In the central portion 11, the corner plug connector 2 has a fastening point 18 in the form of a through hole through which a bolt 19 is inserted, on whose shank a snap ring 19a is fitted. intended to rotatably mount the bolt 19 in the through hole, the thread of the bolt 19 extending over a long distance, e.g. The bolt 19 forms the axis of rotation of the fastening tab 20 which is provided with a threaded sleeve 21 for screwing the screw 19. The fastening tab 20 serves to fasten the front wall panel 1 to the wall and is provided with a longitudinal opening 22 through which the fastening screw is pushed. wall mounting. By rotating the screw 19, it is possible to adjust the distance of the fastening tab 20 from the frame 2, so that the front wall panels 1 can also be arranged at a relatively large distance from the wall. Fig. 8 shows different screwing phases.

According to another variation shown in Figs. 7a and 7b, a spacer snap ring 19b is inserted into the through hole in the corner plug connector 2 so as to secure the screw head 9 axially in the through hole. The screw 19 is then mounted in the corner plug connector 8 rotatably. The main support force is transmitted by nut 19c screwed onto the thread of screw 19 and washer 19d. that abut the vertical strut 3. ·

FIG. 8 further illustrates that the fastening tab 20 may also be a die-cast aluminum or plastic element. FIG. 8 also shows that a hook-shaped element 23 is arranged on the rear side of the fastening tab 20 and is offset rearwardly from the mounting surface of the fastening tab 20. The hook-shaped element 23 may be suspended in a corresponding guide hole of the C-shaped section rail mounted on the mounting wall. As a result, the mounting of the front wall element 1 can be greatly simplified. Optionally, it can be fastened to the C-shaped profile rail through the opening 24. FIG. 9 further shows that the fastening tab 20 may also be provided with a plurality of elongated holes 22 to increase the number of different fastening options. Since the fastening tab 20 is pivotable about a pivot axis in the central portion 11 of the corner plug connector 8, it can be placed in a variety of positions on the mounting wall.

The end portion 25 of the fastening tab 20 disposed around the threaded sleeve 21 is provided with a concentric curvature with a pivot axis whose radius substantially corresponds to the shortest distance A of the pivot axis in the corner plug connector 8 to its outer edge or to the upper edge of the transverse strut 4 This ensures that the upper edge of the end portion 25 and the upper side of the corner plug connector 8 are in common in a plane perpendicular to the front side of the frame 2. This is particularly advantageous when the upper side of the front panel 1 is to be used as a support for a shelf on it. The elements that make up this storage surface, for example gypsum fiber cement or gypsum boards, then rest in the wall area on the abutment areas of the end portions 25 and are automatically aligned at a corresponding angle to the front side of the front wall panel 1.

The aforementioned plug-in structure of the frame 2 has the further advantage that the struts 3 need not be welded together in the next operation. By simply interlocking these parts together, both the stable and the most precise design of the frame 2 are formed, so that the alignment of several end wall panels 1 does not present any difficulties due to the high dimensional stability, as in the prior art. Moreover, the placement of the end wall panels 1 by means of the rotatable fastening tabs 20 mounted on the corner plug connectors 8 is greatly simplified. For the sake of completeness, it should be added that the location of these fastening tabs 20 can be performed at completely different locations of the front wall panel 1 to suitably support the bodies.

FIGS. 5, 6, 11 and 12 each show one embodiment of a front wall member in which the lower end openings 6 of the vertical struts 2 serve to accommodate substantially matching guide rails 26, which are telescopically inserted into the vertical struts 2 and are there held. The guide rails 26 are arranged perpendicular to the longitudinal direction of the lower cross member 27 and are mounted thereon. In the exemplary embodiment shown in these figures, a C-shaped profile rail is used as the guide rail 26. The lower rail 27 is provided with fastening holes (not shown) for mounting on the lower C-section or profile rails mounted thereon. Also provided in the lower end portion of the vertical struts 2 is a hole 16 through which a screw 28 is inserted. A specially formed clamping nut 29 provided with a threaded bore 30 for screwing the screw 28 is inserted into the interior of the vertical struts 2. the clamping nut 29 has an approximately V-shaped cross-section, thereby essentially forming two clamping arms 31. At one end of the clamping nut, a pin 32 is provided on which the spring clip 33 is pressed by its central portion. The resilient caliper 33 has two resilient arms 34 that spring perpendicular to the direction of insertion of the guide rails 26.

The clamping nut 29 is designed so that, upon loosening the bolt 28, it can be inserted into the inside of the guide rail 26, and is connected to the vertical strut 3 by means of the bolt 28. The bolt 28 passes through the guide notch 15 in the guide rail 26. in particular, FIG. 12, wherein the screw 28 is not shown. Then, by tightening the screw 28, the clamping arms 31 are pressed against the guide rail 26 and clamped to the upright strut 2. The resilient caliper 33 now acts so that the resilient arms 34, in the released state of the clamping nut 29, exert an elastic force on the side portion of the guide rail 26. the resilient force is preferably selected such that the entire front wall panel 1 is not automatically displaced by loosening the screws 28, but remains held in position. The displacement of the guide rails 26 in the vertical struts 2 can only be carried out after a certain force has been exerted, but this gives the installer special advantages in mounting the front wall panels 1 since they then do not need to fasten the front wall panels 2 in a certain retracted position. The tightening of the screws 28 then fixes the position or the exact height of the front wall panel 11. The adjustment zone thus formed can be greatly expanded for both the front wall component and the flexibility for positioning at different heights. Here, the installer is not bound to certain heights of the front wall panels 1 and can adjust the wall panels 1 as desired. In addition, the clamping nut 29 may also be a die-cast aluminum part or an injection-molded plastic part with correspondingly bent leaf springs, wherein the clamping nut 29 may be provided with ribs and cavities to prevent material buildup.

The above-described embodiment with telescopically extendable guide rails 26 has the advantage that in the case of extensions or extensions that are as high as the entire wall, two or more front wall panels 1 can be arranged on each other such that the ends of the vertical struts 2 provided with the guide rails 26 face so that the lower bar 27, which is usually at the bottom at the front wall 1, is now at the top and can be connected to the corner of the room, see also Figure 2, right side. By this embodiment it is possible to compensate for variations in the height of the room by suitably extending the guide rails 26 or by inserting them into the vertical struts 2 ·

1, 3, 5 and 13 further show that the front wall member 1 is also provided with a plurality of rungs 35 which are substantially parallel to the transverse strut 4 and which are rigidly connected to the vertical struts 2 ^and they are mainly used for fixing and placing superstructures or extensions. As already mentioned, the vertical struts 2 have a longitudinal web 5 arranged along their length which has a threefold wall thickness than the other sections of the profile, see also FIGS. 14 and 15. This threefold thickness of the longitudinal web 5 gives it a particularly high strength and vertical the stiffness 2 is sufficient. Further, the longitudinal web 5 is provided with a series of square snap openings 36 arranged along the entire length of the vertical struts 2. The snap holes 36 of the two vertical struts 2 (together forming the frame 2) are each arranged at the same height. Preferably, the median distance or pitch of the two latching holes 36 is selected to be very small so that as many bearings as possible are formed on the longitudinal web 5. According to a preferred embodiment, the pitch is about 1 cm.

The snap-in crossbar 35 is provided in the U which is the protrusions 37.

Behind this, the struts 35 are separated by a web substantially of sheet metal bent at each end thereof, intended to be snapped into place, at the end portions of the cross section U from the arms 39, and by bending inwardly, a step 38 is formed so that approximately a profile is formed in the end portions H-shaped. The arms 39 are molded so that latching projections 37 and recesses 40 are formed. The dimensions of the recesses 40 are selected such that their depth is less than the thickness of the longitudinal web 5, but can accommodate the front with the latched projection 37. part of the longitudinal web 5. One arresting plate 41 with a screw 42 is always associated with the end portions of the web 35. When the latching projections 37 are snapped into the latching openings 36, the latching tab 41 rests on the stepped rear bearing surface 43 of the arms 39, the screw being 42 is screwed into the hole 44 with the lock In this way, the crossbars 35 can be arranged depending on a plurality of snap openings 36 at any height of the frame 2, which can be achieved by simply inserting or snapping the snap-in projections 37 into the snap holes 36 and tightening the screw 42 with the locking plate 41. In this connection, it should also be noted that, for ease of installation, suitable marking strips or stickers may be provided on the vertical struts 2, indicating the respective mounting position of a particular partition 21 (e.g., a toilet or shower partition).

Furthermore, it has already been mentioned that partition walls 35 thus used can only be used for numerous superstructures with minor modifications. To this end, the crossbar 35 is provided with receiving holes or threaded holes in its central part. However, this will be described elsewhere in more detail.

It should be noted, however, that it is not shown in the figures that at least one sound-insulating element is provided between the longitudinal web 5 and the crossbar 35 intended to dampen the oscillations originating from the elements located on the cross-bars 21, in particular their operation.

Figures 1, 3, 4 and 16 to 19 show that for the placement of the flush tank 45 arranged between the two vertical struts

3., an appropriately designed adapter is used on both sides

46. This adapter 46 has the advantage of allowing a variety of flushing tanks 45 to be attached to a plurality of snap holes 36 of the longitudinal web 5. This adapter 46 is preferably provided as well as a flushing tank 45. It can be made as a single piece manufactured very simply by injection molding. The adapter 46 consists of a base plate 47 intended to be placed on the respective flange bar 48 provided on the flush tank 45. The base plate 47 is provided with T-shaped elements 49 that are inserted into respective openings 50 in the flange bar 48 and engage with the hook-shaped edges thereof per flange rail 8. In order to prevent unintended unhooking of the T-shaped elements 49, U-shaped notches 51 are provided next to the T-shaped elements 49, thereby providing resilient pressing protrusions 52 which extend into the flange strip 48. Ribs are attached to the base plate 47 on one longitudinal side thereof. 53, 54 arranged perpendicular to each other. These ribs 53, 54 are jointly provided, as shown in particular in FIG. 16, by a U-shaped recess 55, whereby two resilient tongue elements 56 are provided on the vertical arm 53, arranged perpendicularly to the base plate 47. On the flexible tongue side elements 56 facing away from the base plate

47. there are three triangular snap-in elements 57. Truncated pyramid-shaped snap-in pins 59 are provided on the base surface 58 of the arm 58 parallel to the base plate 72, the distance and distance of which are selected such that they can snap into the snap holes 36 in the longitudinal web 5. In order for the triangular latching elements 57 to engage the longitudinal web 5 against the base surface 58 of the arm 54, the distance between the base surface 58 from which the latching pins 59 extend and the triangular latch element 57 is substantially the same as that of The thickness of the longitudinal web 5 can be seen in particular. By means of an adapter, a conventional flush tank can now be fixed in a simple manner on vertical struts 3 of the front wall panels 1, which are provided with snap holes 36. The adapter is released from the longitudinal web 5 with it will also do very easily because the triangular latching elements 57 are provided with inclined ramps for both sensing and mounting. Another advantage of the adapter 46 made of plastic is that it also serves as a sound insulating element.

Referring now to FIGS. 2 and 21-26, variants of the connection of open hollow profiles, in particular C-shaped profile rails, will be described.

FIG. 2 shows that when assembling the end wall panels 1 between the desired superstructures along the mounting wall, it is also necessary to bridge the empty spaces, but they will also be covered with gypsum-fiber or plasterboard panels arranged on the front wall panels 1, which are subsequently lined with tiles . In order to ensure that these plates are sufficiently supported, a connecting strut 60, preferably in the form of C-shaped profile rails, is arranged between the individual wall panels 1. In order to install the joints more easily, a suitable jointing unit is provided which consists of substantially from a connecting plate 61, which is provided with notches 62 open at the edge of the connecting plate 61, and of screws 63, in particular circular-head screws 68 with a square 69 below this circular head, inserted into these notches 62 with respective nuts 64. 62 are provided at their closed end with approximately circular recesses 65, so that an elevation 66 is formed on one side of the connecting plate 61 and recesses 67 on the other side. The diameter D of elevation 66 is selected to substantially correspond to the width of the guide notch 15 provided in the profile rail of the cross section. C-shaped connection. The height E of the elevation 66 is selected to be equal to or less than the wall thickness of the connecting strut 60. Preferably, the height E is only a slight minor. The round head screw 63, which is preferably used for the connection, preferably has a lens shape head 68 whose diameter is larger than the width of the guide notch 15 of the connection strut 60. Therefore, the free end portions that the guide notch 15 of the connection strut 60 may be bounded, with the bolt 63 released, inserted between the lower side of the head 68 and the connecting plate 61. In this case, the connecting strut 60 is raised substantially flush with the elevation 66. The screw 63 is provided with a square 69 under its head 68, which is slidably guided in the notch 62 of the connecting plate 61 but cannot rotate therein. The hexagon nut 64 is provided with a guide piece 70 at its end facing the connecting plate 61, which may be inserted into the recess 67 substantially aligned. It is now apparent from this embodiment that the connection of the connection plate 61 to the connection strut 60 can be carried out very simply and in certain circumstances even with only one hand.

If a conventional spherical head bolt 63 is used, the nut 64, as shown in FIG. 22, may be provided with a recess 71 for locating the square 69. In order to interconnect the same spacers 60, the spacing C of the center of the indentation corresponds to 67 and the elevation 66 are substantially substantially the width G of the connection strut 60. The notches 62 including depressions 67 and elevations 66 are arranged in two rows arranged perpendicular to each other. In the exemplary embodiment shown, three notches 62 and two notches 62 are arranged in one row. The connecting plate 61 is therefore approximately triangular in shape because the row with two notches 62 is arranged perpendicular to the center of the three notch row 62 so that its central notch 62 also belongs to the next row. The open sides of the notches 62 are always facing each other. The connection unit can also be used to connect two different profile rails to which appropriate dimensions have to be changed.

23 to 25 show some connection variants.

FIG. 23 shows a connection point in which two connecting struts 60 are fastened to one of the through connecting struts 60, abutting it perpendicularly from two sides. As the ridges 66 are guided in the respective guide slots 15 in the connecting struts 60, the two rows of slits 62 in the connecting plate 61 are automatically arranged parallel and perpendicular to the connecting connecting strut 60. screw 63 and nut 64 are very simple. Since the connecting struts 60 are always cut exactly perpendicular to their longitudinal distribution, the end faces of the two connecting struts 60 connected to the through connecting strut 60 can be supported against this through-connection, and are additionally always guided by the elevation 66 of the connecting plate 61. the brace 60 correspondingly extremely simplifies the alignment of the tie rods 60.

Fig. 24 shows a junction where two perpendicularly abutting connecting struts 60 are connected to each other. In Fig. 24 it is well seen that the junction plate 61 is triangular in shape with two equal long legs which form an angle of 90 ° to each other . Accordingly, the third arm is arranged to both first arms at an angle of 45 '. The axes extending through the centers of the depressions 67 and the elevations 66, which are located at the apexes of the triangle, are always arranged parallel to the arms so that the connecting struts 60 are fixed at right angles as shown in FIG. such that the shortest distance K between the circumference of the indentation 67 arranged on the triangle overhang and the axis passing through the depressions 67 to which the depression 67 located on the triangle overhang does not correspond to half the width of the linking strut 60. 60, used for management purposes. Furthermore, this fastening method shows that only two screws 63 and two nuts 64 are required to achieve a stable fastening.

FIG. 25 shows a variant of the connection in which two frames 2 of the front wall panels 11 are connected to one another. To this end, two fastening points 18, two threaded holes 13, 14 and an opening 16 in vertical struts 3 are required to connect the connecting plate 61. The distances of the threaded holes 12, 14 and the opening of the fastening point 18 in the corner connector. are selected as needed.

Fig. 26 shows an embodiment in which the connecting plate 61 is slightly modified. In order to be able to connect the connecting struts 60 even in two mutually perpendicular planes, the portion 72 of the connecting plate 61 is bent out at an angle of 90 'from the base plane of the connecting plate 61 such that the recess 73 thus formed substantially corresponds to the external dimensions of the connecting link. 0. Part 72 is also provided with a notch 62, with a corresponding elevation 66 and recess 67, which is further aligned with at least one notch 62 in the base plane of the engagement plate 61, although offset 90 'upward. This makes it possible, for example, to connect one vertical pass-through brace 60 to each other with two connecting struts 60, which abut against it with their ends without the need for special alignment, since the two braces 60 attached to each other automatically engage the connecting plate 61 on through the connecting link 60 in one plane.

26a and 26b, there is provided a connecting bracket 161 which connects to the connecting plate 61 and which, like the connecting plate 61, includes recesses 65 in its arms around recesses 162 to form elevations 66 and recesses 67. Angle between connecting arms the angle 161 is preferably 90 'so that a preferred spatial arrangement of the connecting struts 60 formed by the C-section sections can be made. To automatically achieve an accurate alignment, two mutually assigned elevations 66 on the connecting angle 161 each have such a size and distance from each other. that they can be inserted into the corresponding recesses 67 in the connecting plate 61. The distance of the extension arm of the connecting angle 161 which is precisely spatially positioned by the elevation 66 in the second leg inserted into the recess 67 in the connecting plate 61 from the parallel edge of the connecting plate 61. essentially shows the width G of the C-shaped cross-section profile used to form the connecting strut 60. The use of a special connecting bracket 161 together with the connecting plate 61 provides numerous possibilities for combining them so that the functionality of the front wall element 1 is expanded accordingly.

The connecting plate 61 is preferably made of sheet metal and the elevations 66 and depressions 67 are formed by the embodiment of the recess 65. However, the connecting plate 61 can of course also be made of completely different materials and other manufacturing methods.

Referring to Figures 1, 10 and 27-30, the use of a connecting bracket 74 will be described, which may be used simultaneously as a connecting element. The connecting bracket 74 has a substantially flat abutment surface 75 and a mounting surface perpendicular thereto and abutment surface 77. The attachment surface 76 and the abutment surface are each provided with two mounting slots 78 open on one side. The open side of the fastening notch 78 extends from the abutment surface 75. The median distance L of the two fastening slots 78 of the fastening surface 76 and the abutment surface 77 corresponds to the width G of the C-shaped cross-section joined by the fastener 74, wherein the C-shaped cross-section may be a fastener 60 or the transverse strut 4 of the front wall panel 1. Furthermore, the distance M from the contact surface 75 to the axis of the bolts later inserted into the mounting slots 78 corresponds substantially to the width G / 2 of the C-shaped profile. that the abutment surface 75 lies flush with the upper side of the transverse strut 4, possibly with the end portions 25 of the fastening tabs 20. FIG. 27 further illustrates how the two C-shaped profiles can be connected to one another by this connecting angle 74. Angle 74 allows s bonding the C-section profiles in two planes, thereby providing a plurality of connection options through the corresponding arrangement of the connecting angle 74. Furthermore, the connecting bracket 74 can be very well used to engage and fasten cover elements, for example gypsum-fiber or plasterboard panels, to be fastened to the front wall panel 1.

Furthermore, two rows of projections 80 are arranged on the fastening surface 76 and the support surface 77 on the fastening surface 76 and substantially parallel to the contact surface 75. The distance P of the outer edges of the protrusions 80 in the two rows corresponds to the width of the guide notch 15 in the strut 4, 60 Furthermore, the symmetry axis of the two rows of projections 80 has a distance M from the abutment surface 75 which substantially corresponds to a half width G / 2 of the C-shaped cross-sectional profile. The projections 80 serve to guide and align the connecting angle 74 in the guide notch 15 In this way, the connecting bracket 74 can be very easily aligned on the strut 4, 60 and connected to the struts 4, 60 by means of the screw 79 and nut 81.

The bearing surface 75 is provided with an access opening 82 having an approximate L-shape, the arms of which are arranged parallel to the mounting surface 76 and the support surface 77. The access opening 82 allows the tool, in particular the bolt keys, to access the fastening means, i.e. the bolt 79 and nut 81 in the respective mounting slots 78. Furthermore, the access opening 82 serves as a mounting hole for wall mounting and overhead mounting. For the sake of completeness, it should be added that fastening holes and projections may be provided on the contact surface 75, as shown in FIG. 28, but which do not necessarily correspond to the dimensions of the fastening slots 78 on the fastening surface 76 and the support surface 77. the abutment surface 77 is each provided with openings 76a, 77a. which are used for fastening to light load-bearing walls, especially by self-tapping screws.

The connecting bracket 74 is preferably made of a bent sheet metal as shown in the figures. It follows from the above that the connecting bracket 74 as a multifunctional element can perform several tasks simultaneously. On the one hand, it serves as a bearing surface on the front wall element 1, and on the other hand it can be used for numerous different variants of the connection of the struts 4, 60 formed by the C-section sections.

Further, according to FIGS. 1 to 4 and 31 to 33, a variant of the partition 35, which is intended to accommodate WC bodies, will be described in more detail.

The crossbar 35 consists, as described above, of a beam having a substantially U-shaped cross-section. The crossbar 35 is further provided with recesses 83 in its arms 39. with screws. The connecting plate 84 extends downward beyond the bar 35 and has an approximate T-shape, see Figure 32. The upper T-shaped portion covers the bar 35 at its rear and thus improves its torsional strength.

Resilient tongues 85, which are each formed in one piece with the connection plate 84, are each associated with the recess 83 of the partition 35 in the connecting plate 84. The resilient tongues 85 are provided with protrusions 86 in their end portion facing away from the fixed end which, in the direction of the transom 35 These protrusions 86 are located somewhat beneath these recesses 83 in the region of the recess 83. As in the illustrated embodiment, the recesses 83 form a guide seat which is covered by the connection plate 84 and which is intended for a sliding support for the guide posts 87. For each end wall member 1, two guide posts 87 are provided on the lower bar 27 and are attached thereto. The guide posts 87 extend parallel to the uprights 3 in an upward direction and have a width and thickness to provide a substantially fitting fit therein in the recesses 83 or guide. To form the guide posts 87, a U-shaped flat steel is preferably used to at the same time achieve bending stiffness in the load direction and a relatively low weight structure. Cover elements 88 are provided on the connection plate 84 and are guided in the extension of the guide bearings. This can be achieved either by means of a plate placed on the rail 35 or the connection plate 84, or, as shown in Fig. 31, by two substantially U-shaped plates. As shown in Fig. 33, the elastic force so that the displacement of the lower rail 27 or the guide posts 87 relative to the rail 35 and therefore to the entire frame 2 of the front wall panel 1 can only be achieved after a predetermined force has been overcome. This force is preferably selected such that the weight effect acting on the front wall panel 1 cannot be displaced.

The locking of the crossbar 35 with the connection plate 84 relative to the lower bar 27 is provided by a stop device which is height adjustable and protrudes from the lower ends of the vertical struts 2. The stop device consists essentially of a threaded rod 90 protruding in the extension of the vertical struts 2 which is it can be screwed or unscrewed by means of the adjusting nut 89. For this purpose, a fixed plug 91 is provided at the lower end of each vertical strut 2, which permits the threaded rod 90 to pass through, and at the same time constitutes a support for the adjusting nut 22. 2 by means of another fastening means. The lower end of the threaded rod 90 rests on the lower rail 27. The adjusting nut 89 is designed as a tilting nut for rapid adjustment, so that the installer can make the adjustment very quickly. The threaded rod 90, in conjunction with the adjusting nut 89, allows a very precise and fine adjustment of the desired height of the crossbar 35 and the connection plate 84.

In order to fasten the respective extension parts, respective threaded fastening holes are provided on either the fastening plate 84, see FIG. 32 or on the cover elements 88, see FIG. 1, for which, in the exemplary embodiment shown in FIGS. In this context, an open-ended design of the guide posts 87 also contributes to such a fastening. In this way, the front side of the cover elements 88 lies in one side of the partition 35 in order to spread the pressure caused by the extension elements. for example, when very large bending moments can be applied, the elements 88 of the guide posts 82 / thereby easily deflecting the deflection to an acceptable extent.

Plane with front suspension washbasins leaning against covering

If, however, due to the high load, it is necessary to limit the permissible deformation to a certain value even at higher bending moments, a support leg 94 which supports these parts, see Fig. 1, can be provided to further support the partition 32 or the attachment plate 84, it is installed on the floor and fixed on the back of the mentioned parts. The support of the crossbar 35 can also be carried out by means of fastening tabs 20 arranged thereon. The construction and function of the fastening tabs 20 have been described above.

To improve the guidance of the guide post 87, a further crossbar 35 may be provided with respective recesses 83 for receiving guide posts 87 at the lower end portion of the vertical struts.

The attachment of the crossbars 35, under certain circumstances when using sound insulation elements, is also described above.

Fig. 33 shows that the fastening of the cover elements 88 on the attachment plate 84 is provided by fastening projections 104 which are inserted into the respective receiving openings 103 and which can bend. For this purpose, openings formed by the formation of resilient tongues 85 can also be used. This is particularly the case when both the connecting plate 84 and the cover elements 88 are made of sheet metal by pressing and bending. The resilient tongues 85 can then be made in the attachment plate 84 by simple pressing and bending.

The cover element 88, see Fig. 1, or the connection plate 84, see Fig. 32, is provided with a receiving aperture 95 for receiving and passing the supply tube 96 from the flush tank 45. A ring is provided in the receiving aperture 95, in particular for providing sound insulation. Further, there is provided a holder 98, as shown in FIG. 1, which is preferably made of plastic and which is secured by a snap fastener 99 on the inlet pipe 96. a releasable latch 100 is provided by which the outlet tube 101 is fixed in the holder 98 and at the same time a sound insulation is formed.

For the sake of completeness, it should be added that the threaded fastening holes 92 in the connection plate 84 are arranged in the resilient tongues 102 so that the resilient tongues 102 are tightened to the guide posts 87 by tightening the screws. _C and therefore additionally contribute to safer alignment of superstructure elements. The resilient tongues 102 also take on the function of compensating for the tolerances caused by variations in production.

Furthermore, an embodiment is possible in which the arrangement of all extension elements on the frame 2, whether by means of crossbars 35 or other elements, for example a flush tank adapter 46, is carried out using sound insulating elements. In addition, the elements themselves, for example the adapter 46, can simultaneously represent sound insulation elements. These measures lead to a significant reduction in noise generation and therefore benefit the health of the later user.

FIGS. 34 and 35 show a variant of the partition 35 in which a sound insulation is preferably provided. The partition 35 consists of a base body 105 having a plurality of mounting options for the fluid-flowing portions represented by the apertures 106, 107 and 108. This crossbar 35 is intended, for example, for fixing fittings as shown in FIGS. facing the vertical struts 3, are always fastened to the connecting piece 111 by plastic screws, a damping element 112 always being inserted into the fastening. The connecting part 111 has a bent cross-section with substantially parallel end flat arms 113, 114. a portion of the base body 105 is spaced so that a damping element 112 can be inserted into the gap. This damping element 112 is provided with screw holes 110. Fixing holes 115 are provided in the second end flat arm 114, which are spaced apart by snap holes 36 in longitudinal web 5 vertical struts 3. A locking plate not shown, which is similar to the locking plate 41, is used to connect the crossbar 35 to the vertical struts 3. Thus, the longitudinal web 5 of the vertical struts 2 is located between the second end flat arm 114 and the locking plate. . The locking plate (not shown) is preferably provided with at least one latching projection which engages in the latching hole 36. The sound insulation achieved by this variation of the bar 35 meets the highest permissible noise requirements. Moreover, the separate sound insulation of each part is not necessarily required, but
