Substructure system for shower trays and shower trays [001]

The present invention relates to a 10 15 20 25 30th

Substructure system as used in the sanitary sector. Bathtubs and especially shower trays or even shower trays for example, floor-level showers are set for example on a support frame. This Tragrahitten allows a proper setting of the shower floor to be tiled later, at the same time facilitated installation and adaptation of the drain or siphon. In practical application, however, it has been shown that the conventional support frame constructions only insufficiently take into account specific construction requirements or local building conditions and can be optimized in this regard. Thus, for example, the sound insulation requirements specified by SIA and DIN standards are only poorly met by the conventional support frame constructions can produce sound bridges down and sideways with the local concrete. These sound bridges or the support surfaces of the shower base on the support frame can simultaneously represent cold bridges that cause an unpleasant cold foot contact on the tiled shower floor, the different materials that are used in conventional substructure systems, have different material densities and - properties, in particular with regard to moisture absorption and expansion coefficient under changing temperature conditions. These different material densities or the different temperature properties in turn cause a different shrinkage behavior, which

Furthermore, it may be disadvantageous / that

Granulate beds or fillings that serve the precipitation formation 5 or trickle to fill the cavities around the support frame around between concrete and shower floor with appropriate material, with insufficient compression, which in turn can also lead to subsidence and damage. [007] Known substructure systems sometimes require this

Laying or pouring a so-called gradient concrete, ie the generation of an inclined plane to drain the water to the drain or siphon out. However, this work, as well as the desirable saturated as possible densification of the Dnterbodenkranulats 15 can lead to damage or displacement of the compelling previously positioned precisely positioned drainage pipe system.

Another disadvantage is the fact that the 20 known substructure systems a subsequent

No longer allow leakage control of the drain or siphon, either directly after completion of the installation or later during operation. After the previously described laying or casting of a falling concrete or the compaction of the underbody granulate, the drain or the siphon are no longer accessible.

For this reason, later redevelopment or renovation work are costly and expensive because they require the removal of the previous substructure system and the subsequent attachment of a new substructure system.

A subsequent after a successful installation adaptation - for example, in a renovation - 35 to the required height rate of later selected

Floor tiles or tiles that have a different height than 24/04 2009 FR 16:45 [SE / EH NR 6026] @ 004 24 4 09 16:48

The fact that different materials with 5 different methods are used, another potential disadvantage that different construction professionals must be active and thus warranty conflicts can occur. Another disadvantage is that the concrete, the mortar and the granule binder require drying times, postpone the follow-up work and overall represent an extension to modern drywall with short construction periods and minimized execution risk according to current professional knowledge and expected professional responsibility.

According to the prior art flush showers are also realized with shower floor elements. These

Shower floor elements are predominantly foam boards with a built-in slope, which are covered with a sealing slurry and reinforced with a mesh fabric fleece. The required installation height or required on a case-by-case basis is achieved by means of additional plate supports or by under-filling with different materials. The installation of the drainage system 25 (siphon and drainage pipe) takes place before the setting of the

Shower floor element. The drainage channel or a drainage housing or siphon is connected via a socket, pluggable or screwed. These substructure systems also meet the sound insulation requirements required by SIA and DIN standards only poorly. The lightweight foam panels have a resonance effect and the foam cell structure transmits sound to all sides. 24/04 2009 FR 16:45 [SE / EH NR 6026] 35 16:48

Loads are not stable and, in new condition as well as with aging, are sometimes subject to considerable shrinkage, which in turn can lead to plate and joint damage. 5 The height adjustment of the upper edge of the shower floor element to the upper edge of the underlay floor or screed is cumbersome and time-consuming in the known substructure systems. It is done by lining up another 10 foam boards of variable thickness or by underfilling with granules, sand or similar. A level of height once reached with a great deal of effort can hardly be corrected afterwards, which is necessary, for example, if ceramic floor tiles or tiles with a different thickness than before are to be used in a renovation.

The open-cell foam structure does not allow the attachment of inspection openings. Even the cutting of recesses or generally a subsequent, mechanical machining 20 is not possible, because this would damage the reinforcement or the encapsulation of the foam panels. The foam boards are thus made in advance according to the predetermined fixed dimensions. 25 [0018] The gutter or drain housing must be in front of the

Destroying the shower floor element.

[0020; The prior art also discloses combinations of support frame with shower floor elements / in which the support frame 5 is height adjustable by means of threaded legs. As a first step, the installation of the support frame on which after adjustment of the previously measured height rate the shower floor is applied. The connection of the water outlet via the shower channel and the drain body is again via a sleeve. 10 However, a disadvantage remains with these

Combinations of a support frame and a Duschbodeneiement that the Eöheneinstellung and at the same time necessary leveling of the support frame is cumbersome and time consuming. Thus, a setting position for the shower floor element is reached only after repeated measuring and leveling operations, which should preferably be right at the first attempt when placing the shower floor element. The installation height of flush-mounted showers depends on the height of the underlay floor or screed and usually varies between 40 and 300 mm. Covering this entire 260 mm adjustment range may not always be guaranteed by the roots, or at least not economical, so it can be detrimental to have to provide thread roots that match the specific field conditions. In addition, this circumstance represents a possible source of error. [0023] In order to meet the sound insulation requirements according to SIA and DIN standards,

To meet standards. these combined substructure systems will be without side supports, quasi "floating". set. This fact, in turn, represents an instability which may overburden a sealing tape which is overlapped on the top of the site concrete and the floor panel or the joints between the concrete floor and the shower floor panel, which in turn 24/04 2009 FR 16:45 [SE / EH NR 6026] @ 007 24 4 09 16:49

Even with these combined substructure systems must 5 the gutter or the Abiaufgehäuse before laying the

Shower floor element to be installed in this. The water-conducting connection of the drainage channel or the drainage housing to the siphon is also successful again via a sleeve. Thus, the siphon and the drainpipe are to be positioned accurately before laying the 10 shower floor element and secured against displacement.

These combined substructure systems also do not permit tightness checks. For renovations, maintenance and 15 service, the complete substructure system must be expanded again.

The object of the present invention is to provide a substructure system that avoids the disadvantages just described 20 as far as possible and is optimized in terms of its later properties in the assembled operating condition, but also in terms of its mountability.

The solution of the problem consists first in the arrangement of a substructure system from a height-adjustable support frame and a support plate, the at least one assembly or. Has revision opening.

This .Montage- or inspection opening in the support plate is approximately centrally or else arranged offset to its edge and designed and dimensioned so that when mounting, with already aufgelegtter or pre-mounted support plate, the height of the upper edge of the support plate can be adjusted flush with the height of the upper edge of the underlay floor or screed or ready-made floor. This is according to the invention ensured by the elements, with 24/04 2009 FR 16:45 [SE / EM NR 6026] @ 008 24 4 09 16:49

This results in the significant advantage that no previous measurements and 5 any Probeauflegung the support plate must be made. In addition, tightness checks on the drainage system are feasible, both during assembly and during later operation. 10 According to the invention, the support plate may optionally itself represent the shower floor plate to be tiled later or it may be draped and fixed on the support plate a separate shower base plate, which is adaptable in the same way to the height of the upper edge of the Dnterlagsbodens or screed or finished floor ,

A further embodiment variant according to the invention provides that the support frame is integrated into the support plate, which is at the same time the uppermost shower floor panel or into the support plate on which a separate shower floor panel is still placed. This means that it is dispensed with a separate frame construction and the support plate or the shower base plate itself form the frame on which the elements are arranged, with which the height is adjustable, or other 25 inventive fastening and positioning elements, hereinafter yet to be described.

The present application thus defines, under the general term of a support device, the following 30 basic variants: A height-adjustable support frame on which a support plate and a shower base plate can be placed and fixed, a height-adjustable support frame on which a shower base plate can be placed directly is fixable, 35 - a height-adjustable support plate on which a

The support plate or the shower base plate preferably has an underside, which is designed plan and 10 corresponds in the mounted state of the horizontal. The top of the support plate or the shower bottom plate, however, is preferably provided with at least one surface which is at an angle to the horizontal. Here, embodiments are conceivable in which a single surface forms an oblique plane, at which the water in a laterally arranged

Shower channel or drains into a drain body. However, it is also possible, for example, for two surfaces to run toward an approximately centrally placed shower channel or a drainage housing or, for example, four surfaces for an approximately centered or even an eccentrically arranged outflow. These surfaces can have congruent or different basic shapes.

Another possible embodiment variant looks 25 described the precipitation formations in the shower floor panel itself, whether it is the support device consists of a preferably in this case, planning support plate and an attached shower floor plate or only a shower floor plate. 30 In the embodiment variant in which a

Shower bottom plate is placed on the support plate, it is advantageous if the support plate forms the necessary slope and the shower bottom plate thus a normal, both sides plane (top and bottom parallel to each other) can be plate. However, it is also feasible to design variants in which an overall gradient results from the addition of a support plate 24/04 2009 FR 16:45 [SE / EU NR 6026] @ 010 24 4 09 16:49

Gradient and a shower floor plate gradient results.

Sine another embodiment variant of the support plate and the shower base plate provides a normal, evenly 5 strong plate, but by means of different levels - preferably in the support plate or shower base plate integrated - editions as a whole is inclined. This embodiment variant or even one in which the bottom of the support plate or the shower base plate at least 10 forms two inclined surfaces, so that the cross section of the support plate tapers approximately in the middle, can be advantageous in terms of a free arrangement of the drainage system.

The design variants of the support plate or the shower base plate described so far disclose an underside lying horizontally in the mounted state or at least supports which form support surfaces lying horizontally in the mounted state. However, embodiments of support plates or shower base plates 20 are hereby disclosed, in which the underside or the support surfaces are inclined or concave and thereby result in more extensive and more powerful adjustment options, for example with threaded legs, which are preferably both at their lower and at their upper end in ball joints stand. With ball joints, at least at the upper end of the thread roots, for example, a cost-effective variant of a substructure system is well feasible, in which only a single fall direction is provided towards a laterally arranged shower channel 30 or a laterally arranged drain housing. The fact that the ball joints exert lateral support of the support plate or the shower base plate, a common, double-sided plate, without integrated slope, can be raised or raised on one side. In principle, the same effect can be achieved even with threaded sockets or holders for the thread legs, which can be used to produce the desired 24/04 2009 FR 16:45 [SE / EH NR 6026] @ 011

Inclination angle from the outset have. This means that the thread roots are inclined in the horizontal position of the support plate or the shower base plate. If the support plate or the shower base plate, however, has reached the desired angle by screwing the roots, the threaded feet align themselves in the vertical position, which is also required for carrying the intended loads without unriskinschte side forces. The cost-efficiency of these design variants, either with ball joints or with inclined thread roots, is expressed on the one hand by the fact that the costly development of a slope is eliminated. On the other hand eliminates the need to use correspondingly thick plate blocks, from which the slope can be worked out at all and this in turn can represent a significant material savings of costly material from which the support plates and the shower floor panels are made.

In the case of the embodiment variant of a

Substructure system with a support plate, which can be subsequently placed and attached to a separate shower floor plate, it is possible to equip not only the support plate, but also the shower base plate with a mounting or inspection opening. According to the invention, this opens up a multiplicity of arrangement variants which can be selected depending on the structural conditions, materials used and / or expected mechanical or hygroscopic load: The support plate has an assembly or inspection opening which can be covered with a flush and tight cover; the shower floor panel, however, has no mounting or inspection opening; The shower floor plate is tiled and must therefore be completely removed during revisions. - The support plate has a mounting or inspection opening, for which no sealing cover is provided and the shower base plate is configured as above. 24/04 2009 FR 16:45 [SE / EH NR 6026] @ 012 24 4 09 1 6:50

The mounting or inspection opening of the shower floor panel can be closed tightly with a corresponding cover and the tiles are laid over it. With revisions now only the tiles are to be removed from the shower floor plate. 10 - The support plate has a mounting or inspection opening, with or without cover, and the shower base plate also has one, but with a lid, for example, which is separately tiled. In any case, whether flapped or not, this cover is removable at revisions without prior removal or destruction of anything else.

The inventive support device preferably has a plurality of height adjustments or novel thread roots, which are each height adjustable with an endless threaded rod 20. The endless threaded rods are in

Shoes or relatively flat Bufferscfceiben, which are preferably made of a soft and little sound-transmitting material, for example made of rubber. Furthermore, the endless threaded rod is preferably mounted with a ball joint in the shoe, so that rotations of the endless threaded rod are not stopped prematurely by a contact friction of the shoe on the concrete. For a convenient implementation of the rotation of the endless threaded rod, it is equipped with a square or a key holder. The Schlüsselaufnähme 30 may in principle also be arranged on the upper head of the endless threaded rod, for example, for a Allen key or Torx and be reached by a correspondingly positioned mounting hole in the support plate and / or the shower base plate. [0040] According to the invention, these so-called endless threaded rods are in contrast to prior art arrangements 24/04 2009 FR 16:45 [SE / EM NR 6026] @ 013 p. 14 +41 41 759 02 61

Namely, the arrangements according to the prior art disclose a threaded rod which is fastened with its upper end fixed below the desired support point in Tragrahir.en 5 and thus provides a height adjustment, which alone results from how far a threaded root can be screwed down from the fixed threaded rod without the thread root becoming unstable. In other words, the threaded legs of the prior art disclose adjustability of 10 a lowest height position hl = 1 + S, where 1 corresponds to the operative length of the threaded rod and S corresponds to the thickness of the base of the threaded leg, to a highest height position h2 = 1 + S + A, where A is the Aufschraubmass with which the thread root of the fixed threaded rod 15 can be screwed down. The maximum Aufschraubmass can be at best equal to the total height of the neck of the threaded foot minus the height of a threaded nut. The more such a threaded foot assembly is screwed, the more unstable it is because the force application point threaded rod nut 20 is increasingly distant from the upper force attachment point threaded rod support frame with increasing height adjustment and at the same time more and more - also depending on the height of the Threaded feet - removed from the point of application of base base concrete. And the farther these points of application 25 are from each other, the more the leverage changes to the detriment of stability.

The height adjustability of a support frame according to the invention is realized differently in that on the one hand 30 (endless) threaded rod offset adjacent the support surface of the support frame or the support device is arranged and on the other hand, the support frame and the support clearly surmounted in their overall length. In addition, not a threaded root is rotated with a nut on a fixed arranged 35 Gewindescange, but the (endless) threaded rod in a fixedly arranged nut.

• IM IM 13 is cut directly into a hole in the bracket. At the lower end of the endless threaded rod according to the present invention, in accordance with the state of the art, there is a bolt-on base foot which, however, remains screwed in at a maximum of 5 and does not serve to adjust the height. The base foot can therefore be designed significantly flatter than a buffer disk.

The upper attachment point or rather 10 point of force application of the thread root according to the invention is no longer located on the upper head of the threaded rod, but in an L-shaped holder or in a fixedly arranged on this bracket nut. The upper force application point of the thread root according to the invention thus travels through rotations 15 of the endless threaded rod over its entire length. The inventive height adjustment is thus characterized by a much greater adjustability with higher stability, because by the laying of the upper force application point in the fixed nut on the holder 20 (and no longer in a threaded in the self-thread nut) only two force application points occur. The upper force application point is the nut itself or the holder and the lower force application point is the lower end of the endless threaded rod. In the arrangements according to the state of the art, however, there are always three points of application of force, namely one at the upper end of the threaded rod, a second at the nut located in the neck of the threaded leg and a third at the lower end of the spine. The inventive height adjustment thus guarantees per se 30 due to the lower number of Kraftansatzpunkten a higher rigidity, which is largely determined by the flexural strength of the endless threaded rod itself.

After setting the required height, the endless threaded rod can be fixed with a counter nut to the fixed nut or the threaded hole 24/04 2009 FR 16:45 [SE / EM NR 6026] @ 015> 4 4 09 16:51

Design variant of the last-described height adjustment with an endless threaded rod in a threaded sleeve pursues an additional optimization of sound decoupling · For this, the hole for receiving the threaded sleeve in the L-shaped bracket or the bridge support has a larger diameter than the outer diameter of the external thread of the threaded sleeve · The latter is thus easily inserted into the bore and fixed with at least one nut at the top of the bore and at least one nut on the underside of the bore. The nuts are here preferably each with a disc and another disc of a damping material (for example, rubber) underlaid. The threaded sleeve may instead of one of the two nuts, which flanged to the web support, also form a fixed collar, which is preferably formed at the upper end of the threaded sleeve. This fixed collar can preferably be inserted into the bar holder, again preferably in a receptacle, which no longer allows a positive rotation of the threaded sleeve and thus the remaining nut can be tightened. However, further preferred is an embodiment variant in which no positive reception can produce a possible sound bridge between the threaded sleeve and the web support by the fixed collar of the threaded sleeve can not get into direct contact with the inner walls of the web support.

Rotations of the endless threaded rod 14c thus cause a lifting or lowering of the supporting device 300f. The endless threaded rod 14c can also be screwed in so far that an upper end 66a of the endless threaded rod 14c falls below the level of a shower plate top 52b, because a key socket 63a at the upper end 66a of the endless threaded rod 14c through a mounting hole 62a remains operable in the shower floor panel 50b. The mounting hole 62a can be glued after completion of height adjustment of the support device 300f and any necessary cutting or caps of the endless threaded rod 14c with a stopper not shown and then the shower bottom plate top 52b are laid with floor panels or tiles. Preferably, the endless threaded rod 14c can be fixed after the height adjustment with a lock nut 17c on the lower end face of the threaded sleeve 61 61 as shown. But the lock nut 17c can also be better accessible through the mounting hole 62a and tightened against it with a socket wrench on the upper end side of the threaded sleeve 61. It is also possible to cut off the endless threaded rod 25 14c in such a way that the upper end 66a of the endless threaded rod 14c comes to lie below the upper end side of the threaded sleeve 61 in the desired height position and thus also a grub screw as contingent fixing of the endless threaded rod 14c in the threaded sleeve internal thread 65 30 can be screwed.

FIG. 8 shows a design variant of a multi-part shower floor panel 50c according to the invention which is furthermore shown schematically and in perspective. It consists of a plate part which comprises the drainage system and is thus designated in the following as drainage plate part 69 and can be laid on another plate part, which in principle corresponds to the design variants of support plates or shower floor plates described so far. Plate member 70 is designated. The drain plate portion 69 is preferably pre-assembled at the factory with a gutter 71 and mounting holes 62b-62e through which endless threaded rods 14d, 14e and 14f are operable in height adjustments 200c, 200d and 200e as heretofore disclosed. Furthermore, the drainage plate part 69 has a step-shaped, positively shaped connecting edge 72 with a bearing surface 74a into which rivet nuts 75a-75c are inserted.

[001QC] The laying-on plate part 70 has a corresponding stepped, negative connecting edge 73 with a bearing surface 74b. After the two bearing surfaces 74a and 74b have been placed on top of each other, the laying plate part 70 can be screwed with countersunk screws through countersunk holes 76a-76c into the rivet nuts 75a-75c and thus firmly connected to the drain plate part 69.
