Abstract

The wall-section is esp. for a sanitary installation, the cross-member fitting between two uprights of the section frame and accommodating one or more pipes. Connectors (111) join the ends of the member body (105) to the uprights, and parts of their surfaces overlap the body ends. Elastic damping members (112) fit between the overlapping surfaces, and damping fixing devices (100) pass through the member body, the damping members and the connectors at the ends. The connectors can be of stepped cross-section with parallel end flanges, one (113) overlapping the body and the other (114) fitting on to the frame member. Each damping member can comprise a body of plastics or pref. rubber, while each fixing device can consist of a plastics screw, rivet or clip.

Description

The invention relates to a crossbeam for a pre-wall element, especially for plumbing, at least attachable between two struts of the frame of the pretext element and can be attached to the components through which a fluid can flow are, the truss essentially from its truss body and in each case at the end regions facing the struts of the truss base body, the struts with the truss base body connecting connectors and and surface areas of the connecting piece and the cross member base body overlap.

Such a traverse is known from DE 34 10 499 A1.

Furthermore, in the DE-Z: Sanitary and heating technology, 1993, issue 5, page 62 an insulation part type 50 AN, which a double angle and one located at one end Has insulation rubber.

Traverses of this type are usually used for pre-wall elements used to attach a wide variety of attachments such as Fittings to attach. A disadvantage of the sanitary installation are often the flow elements arranged on the crossbeams caused noise. Expect sharper Determinations and improvements in well-being of a later one Users of such a pretext lead in the latter Time to increase the possibilities of noise reduction is being considered. So it is known, for example, the fittings through appropriate elastic elements at their connection point decouple sound on the crossbar. Through this Measure, a considerable noise reduction is already achieved, but efforts are still being made to improve them.

It is therefore the object of the present invention to make a traverse for a pre-wall element, especially for the sanitary installation, to provide an easy to assemble offers to reduce noise.

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

The inventor has recognized that the provision of a damping element in the area of the connection point between the strut and the crossbeam base with the interposition of a connector has such a high noise reduction that on a more costly individual decoupling of all on the crossbar attached components can be dispensed with. The advantage of this Invention is that the decoupling of the actual Transition point from the components through which the fluid flows the possibly built up by several pretext elements Stand wall have a much greater impact on sound decoupling has as the sound decoupling of the components of a traverse self.

The connecting piece can preferably have a stepped shape Have a cross section with two substantially parallel end webs, the first end web being the same as the cross member base provides overlapping surface area and the second end web can be attached to a strut of the frame. The stepped design of the connector gives the connector a resilient, and thereby additionally damping effect in the axial direction of the traverse.

A damping element can be achieved particularly cost-effectively. if this is made of a plastic body, preferably rubber, consists. This material has the necessary damping properties also over the expected service life.

To make the self-damping as simple and inexpensive as possible Providing fastener, this can by a Plastic screw, a plastic rivet or clip formed be. The damping of the fastening element prevents that structure-borne noise from the truss body to the Connectors are transferred via the fastener.

Another way of designing the fastener consists of forming this as a screw whose Bottom of the head is arranged on an elastic disc. Through the sound decoupling or damping of the fastener there is also a transition from structure-borne noise to that Truss base body avoided on the connecting pieces.

Favorably, fastening openings can be made in the second end web be arranged, the pitch of one with a row of perforations provided strut of the frame dimensionally adapted are, with the end web at least one corresponding to the Fastening openings associated openings provided locking plate is assigned connectable by fastening means, the at least one locking lug for snapping into the hole pattern the strut has.

The pre-wall element 1 used for the sanitary installation can be modified for different applications e.g. show Figures 1, 3 and 4 a pretext element for toilet installation and Figures 5 and 6 Corresponding pretext element for attaching a wash basin and fittings. The individual configuration is discussed below discussed in more detail. But there are also others Conceptions of pre-wall elements, especially the extensions regarding, conceivable, to the different application purposes are adapted, e.g. Shower, bath tub, urinals, bathroom furniture etc.

The pre-wall element 1 has a frame 2, which consists of two Hollow sections formed vertical struts 3 and one from one open hollow profile, preferably a C-profile, which formed Vertical struts 3 holding cross strut 4 at a distance from one another. The hollow profile of the vertical struts 3 consists of a roll-formed Box profile, preferably rectangular cross-section, with one side of it, in the middle of a shorter transverse side thereof, arranged longitudinal web 5. The longitudinal web 5 has the three times the material thickness of the rest of the hollow profile because it produced by folding one end of the sheet over the other end of the sheet has been. Galvanized sheet steel is preferred as the material used, painted before profiling or with a colored film is coated.

The C-profile of the cross strut 4 and the box profile of the vertical struts 3 preferably have the same opening cross-section on the inside. The respective end openings 6 and 7 of vertical strut 3 and cross strut 4 serve as receptacles for a corner connector 8, with its Plug approaches 9 and 10 in the end openings 6 and 7 accordingly engages essentially in a precise fit. As in the figures too can be seen, the two plug inserts 9, 10 by 90 ° to each other staggered so that the corner connector 8 a L shape and the lugs 9, 10 represent the L-legs. The corner connectors 8 form at least the upper ones Corners of the frame 2. A central area 11 of the corner connector 8 forms the visible corner. This is the middle area 11 preferably the outer contour of vertical struts 3 and cross strut 4 adapted or over this. By this configuration, stop surfaces 12 are formed on which the vertical struts cut perpendicular to their longitudinal axis 3 and cross strut 4 can strike flat. When plugging together the struts 3, 4 by means of the corner connector 8 high dimensional accuracy is thus automatically established.

Furthermore, each plug insert 9, 10 has a cross to respective plug direction extending threaded bore 13, 14th on, in the appropriate screws for attachment to the struts 3, 4 can be screwed in. In the cross strut 4, the parallel to the longitudinal extension of the guide opening 15 can be used. The vertical strut 3 can do this accordingly Have opening 16. The attachment e.g. at the Vertical strut 3 can also be done in such a way that in the threaded bore 13 a countersunk screw is used, which does not have the outer surface of the connector projection 9 protrudes, and the Opening 16 has a diameter which is smaller than that Head of the screw used, but is large enough to access to ensure by a tool on the screw head. The screw head can then against the inner wall of the Vertical strut 3 clamped when the corner connector 8 is inserted become. In this embodiment, the attachment the corner connector 8 on the struts 3 also from the front of the frame 2, since the fasteners are not survive.

The corner connector 8 can with its plug inserts 9, 10 also as e.g. Aluminum die casting or plastic injection molding, can be executed and for this reason corresponding Stiffening ribs and cavities to avoid material accumulation exhibit.

In the central area 11, the corner connector 8 has a fastening point 18 in the form of a through hole through which a screw 19 can be inserted, on the shaft Snap ring 19a is clamped to rotate the screw 19 in fix the through hole, and its thread on the Back of the corner connector 8 over a large area, e.g. 10 cm, protrudes. The screw 19 sets a pivot axis for a mounting tab 20, the corresponding to Receiving the screw 19, a threaded sleeve 21 arranged thereon having. The fastening tab 20 is used for wall mounting of the wall element 1 and accordingly has an elongated hole 22 on, inserted through the wall mounting screws can be. By turning the screw 19 can adjust the distance of the fastening tab 20 to the frame 2, so that the corresponding pretext elements 1 for one relatively large wall clearance area can be used.

The above-mentioned plug-in construction of the frame 2 continues to offer the advantage that the struts 3, 4 are not in a subsequent Operation must be welded. Because of the simple Putting these components together is both a stable and an extremely precise design of the frame 2 is also possible, so that a series of multiple wall elements 1 little problems due to the high dimensional accuracy is. In addition, the attachment of the pre-wall elements by the on the corner connectors 8 attached pivotable mounting brackets 20 very greatly simplified. For the sake of completeness it should be mentioned that the attachment of such fastening tabs 20 is also quite possible other points of the pre-wall element 1 for appropriate support can be used by extensions.

FIGS. 5 and 6 each show an embodiment of the pre-wall element 1, in which the lower end openings 6 of the Vertical struts 3 for receiving a substantially precise fit Serve guide rails 26 which are telescopic in the vertical struts 3 are supported. The guide rails 26 are vertical for the longitudinal extension of a lower cross strut or floor bar 27 arranged and attached to this. In the in the figures illustrated embodiment are used as guide rails 26 C profile rails inserted. The bottom bar 27 has mounting holes, not shown, for attachment to Floor or a C-profile rail attached to it. At the lower end of the vertical struts 3 is also located an opening 16 through which a screw 28 can be inserted is. Inside the vertical struts is a specially designed one Clamping nut inserted, in which there is a threaded hole 30 for screwing in the screw 28.

The adjustment range created in this way allows a wall element to be used 1 the flexibility in terms of attachment different heights can be expanded very much. The installer is not bound to certain pretext element heights and can adjust them according to customer requirements.

The configuration described above with the telescopic Guide rails 26 also have the advantage that at wall-high Expand two or more pre-wall elements on top of each other can be made that with the guide rails 26th provided ends of the vertical struts 3 point away from each other, so that in the one wall element the bottom bar 27 now located at the top and connected to the ceiling of the room can be (see also Fig. 2 right side). Through this Design can be deviations in the room heights without further by the corresponding displacement of the guide rail Realize 26 in the vertical struts 3.

It can be seen from FIGS. 1, 3 and 5 that the pre-wall 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 attachments can be used. As mentioned above, have the vertical struts 3 in their longitudinal extent extending longitudinal web 5, which is three times the wall thickness of remaining profile. Triple the wall thickness of the longitudinal web 5 gives it a particularly high strength and Vertical strut 3 sufficient rigidity. Furthermore points the longitudinal web 5 also along the longitudinal extent of the Vertical strut 3 rows of perforated grids with square ones Locking holes 36 on. The locking holes 36 two a common Vertical struts 3 forming frame 2 are each on the same Height. The center distance between two locking holes 36 is preferred selected very small in order to take as many pictures as possible on the longitudinal web 5 to provide. The center distance is approximately 1 cm.

Furthermore, it should be mentioned in advance that one designed in this way Traverse 35 by only minor modifications can be used for numerous cultivation purposes. For this the cross member 35 has corresponding receiving bores in its central region or threaded holes. But this is what is going on elsewhere.

Referring to Figures 1, 3 and 4 is too recognize that to attach one between the two vertical struts 3 arranged cistern 45 on both sides appropriately shaped cistern adapter 46 is used. The cistern adapter 46 has the advantage that it is the connection a wide variety of cisterns 45 to the row of perforations of the longitudinal web 5 allows. The cistern adapter 46 is made preferably like the cistern 45 made of plastic and can therefore using the injection molding technique very simple one-piece be carried out.

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 will be between each Wall elements 1 connecting struts 60, preferably in Form of C-shaped rails arranged.

An exemplary embodiment of the traverse according to the invention is described below with reference to FIGS explained in more detail about the inclusion of toilet attachments in the Location is.

The cross member 35 consists of an essentially in cross section U-shaped support. Furthermore, the traverse 35 Recesses in their U-legs. On both U-legs there is a connection plate 84, with this means Screws is connected. The connection plate 84 is at the bottom about the cross member 35 and has an approximately T-shaped shape on. The upper crossbar of the T-shape covers the traverse 35 their back and thus improves their torsional properties.

The recesses 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 at its end area facing away from the fixed end 86 on in the direction of the traverse 35 over the rest Surface of the connecting plate 84 protrudes. The spring nose 86 is in the area of the recess or, as in the shown embodiment, slightly below these. The Recesses form a guide receptacle through the connection plate 84 is covered, for slidably accommodating Guide rails 87. There are two for each wall element 1 Guide bars 87 arranged on a bottom bar 27 and with this attached. The guide bars 87 extend in parallel to the vertical struts 3 upwards and have a width and Thickness leading to a substantially snug fit in leads the recesses or the leadership. As a material a U-shaped bend is preferably used for the guide bars 87 Flat steel used to be one in the load direction rigid, but still relatively easy to achieve. On the connection plate 84 are in the extension of the guide receptacles leading cover elements 88 arranged. On the one hand, this can as shown in Fig. 1, by a on the cross member 35 or Connection plate 84 attached plate, or by means two substantially U-shaped sheets. Which is in the guide rails 87 are located acted upon by the spring lugs 86 with a spring force, so that moving the bottom bar 27 or the guide rails 87 with respect to the cross member 35 and thus the entire frame 2 of the pre-wall element 1 only by overcoming a predetermined one Force can take place. This force is preferably chosen so that a shift due to the weight forces on the wall element 1 not happened.

Locking the traverse 35 with the connecting plate 84 opposite the bottom bar 27 is carried out via a stop device, which is adjustable in height from the lower ends of the vertical struts 3 looks out. The anchor device consists of essentially from an extension of the vertical struts 3 this in and by means of an associated adjusting nut 89 unscrewed threaded rod 90. For this purpose, in the lower At the end of the vertical strut 3, a plug 91 is fixedly arranged, which enables the threaded rod 90 to be passed through, however, is a support for the adjusting nuts 89. The plug 91 can be a collar on the front of the Support vertical struts 3 or with this over other fasteners connected. The lower end of the threaded rod 90 is supported on the bottom bar 27. The adjusting nut 89 is designed for quick adjustment as a tilt nut, so that the installer makes a setting as quickly as possible can make. The threaded rod 90 in interaction with the Nut 89 allows a very precise and sensitive adjustment the desired height of the traverse 35 and connection plate 84.

To attach appropriate attachments are either on the Connection plate 84 or on the cover elements 88 (Fig. 1) corresponding Fastening threaded holes arranged. In this There is also a connection between the interior design of the guide rails 87 such an attachment benefits. So the pressure the add-on elements can be accommodated over a large area the front of the cover elements 88 with the front of the Traverse 35 in one plane. Because e.g. when attaching a hanging toilet bowl very large bending moments the cover elements 88 are supported on the guide rails 87, which makes deflection very easy to a tolerable Measure 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 for further support the cross member 35 and the connecting plate 84 support these parts Heavy duty foot 94 (Fig. 1) may be provided on the floor space is mounted and at the back of the mentioned parts is attached and supports them. A support the traverse 35 can also have fastening tabs 20 take place, which are arranged accordingly. The structure and the operation of the mounting tabs 20 is from the known above.

In order to improve the guidance of the guide rail 87, a further cross member 35 with corresponding recesses 83 for receiving the guide bars 87 at the lower end of the vertical struts 3 be arranged.

7 and 8 is a truss variant shown in which the sound decoupling according to the invention has been realized. The cross member 35 has a cross member base body 105, in which numerous mounting options in the form of openings 106, 107 and 108 for attachment of components through which a fluid can flow can be attached. This traverse 35 can e.g. as can be seen in FIGS. 5 and 6 can be used to attach fittings. The each Struts 3 facing end regions 109 of the cross member base 105 are each with plastic screws on a connector 111 attached with the interposition of a damping element 112. 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 cross member base 105 at a distance, so that the damping element 112 can be inserted. The damping element 112 has corresponding openings for the screws 110. On the second End web 114 are provided fastening openings 115 which the Pitch of the arranged in the longitudinal web 5 of the vertical struts 3 Hole grid row are dimensionally adapted. To the traverse 35 with to connect the vertical struts 3, is not shown Locking plate used, which is similar to the locking plate 41 is arranged so that the longitudinal web 5 of the vertical struts 3 between the second end web 114 and the locking plate located. The locking plate, not shown, has preferably at least one latch, which correspondingly in a Locking hole 36 engages. The achieved by this truss variant Sound decoupling meets the highest requirements for permissible Noise reduction requirements. In addition, the separate decoupling of each component is not absolutely necessary, however, can still run.
