Definitions

  • the present invention relates to a substructure system as used in the sanitary area.
  • Bathtubs and in particular shower trays or only shower trays for, for example, floor-level showers are placed on a support frame, for example.
  • This support frame allows the shower base to be tiled to be set appropriately, while at the same time making it easier to install and adapt the drain or siphon.
  • These sound bridges or the contact surfaces of the shower base on the support frame can simultaneously represent cold bridges that cause uncomfortably cold foot contact via the tiled shower base.
  • the different materials used in conventional substructure systems have different material densities and properties, especially with regard to moisture absorption and expansion coefficient under changing temperature conditions. These different material densities and the different temperature properties in turn cause different shrinkage behavior, which and can cause joint damage or leaks.
  • granulate fillings or fillings which serve to form slopes or to fill the cavities around the supporting frame between in-situ concrete and shower base with appropriate material, can trickle out with insufficient compaction, which in turn can lead to subsidence and damage .
  • Another disadvantage is the fact that the known substructure systems no longer allow the leakage control of the drain or siphons to be checked, either immediately after installation has been completed or later during operation. After the previously described laying or pouring of a gradient concrete or the compaction of the underbody granulate, the drain or the siphon are no longer accessible.
  • Another disadvantage is that the concrete, the mortar and the granulate binder require drying times, postpone the follow-up work and are an overall extension compared to modern drywall construction with short construction periods and minimized execution risk according to today's professional knowledge and expected professional responsibility.
  • floor-level showers are also implemented with shower base elements.
  • These shower base elements are predominantly foam panels with an integrated slope, which are covered with a sealing slurry and reinforced with a mesh fabric.
  • the required installation height or required from case to case is achieved with additional panel supports or by stuffing with different materials.
  • the water drainage (siphon and drain pipe) is installed before the shower base element is placed.
  • the drainage channel or a drain housing or siphons are connected via a socket, which can be plugged or screwed.
  • Foam sheets are also not stable against mechanical loads and, when new and with aging, are subject to a sometimes considerable shrinkage behavior, which in turn can result in board and joint damage.
  • the height adjustment of the top edge of the shower base element to the top edge of the sub-floor or screed is cumbersome and time-consuming in the known substructure systems. It is done by placing additional foam sheets of variable thickness or by filling them with granules, sand or similar. Once the height ratio has been reached with a lot of effort, it can hardly be corrected afterwards, which is necessary, for example, if ceramic floor slabs or tiles with a different thickness than before are to be used in a renovation.
  • the open-cell foam structure does not allow inspection openings to be made. It is also not possible to cut recesses or to carry out subsequent mechanical processing because this would damage the reinforcement or the sheathing of the foam panels.
  • the foam sheets are thus made in advance according to the specified fixed dimensions.
  • the drainage channel or the drainage housing must be installed in this or in parts of it before laying the shower base element.
  • the drainage connection of the drainage channel or the drainage housing is made via a sleeve.
  • the siphon and the drain pipe must be positioned accurately before the shower floor element is installed and secured against displacement.
  • the prior art also discloses combinations of support frames with shower base elements in which the support frame can be adjusted in height by means of threaded feet.
  • the support frame is installed, on which the shower base element is placed after setting the previously measured height ratio.
  • the water outlet is connected via the shower channel or the drain housing via a sleeve.
  • a disadvantage of these combinations of a support frame and a shower base element is that the height adjustment and, at the same time, the necessary leveling of the support frame is cumbersome and time-consuming.
  • a setting position for the shower base element is reached only after repeated measuring and leveling processes, which should also be correct right away when the shower base element is placed on it.
  • the installation height of floor-level showers depends on the height of the subfloor or screed and usually varies between 40 and 300 mm. Covering this entire adjustment range of 260 mm cannot always be guaranteed by the threaded feet or at least cannot be economical, so that it may prove disadvantageous to have to provide threaded feet that correspond to the special conditions on site. This is also a possible source of errors.
  • the drain channel or the drain housing must be installed in the shower base element before laying it.
  • the water-carrying connection of the drainage channel or the drainage housing to the siphon is again via a sleeve. This means that the siphon and the drain pipe must be positioned precisely before installing the shower base element and secured against displacement.
  • the disclosure DE 100 14 044 A1 discloses a tub support with height-adjustable feet, wherein a substructure system is described with a support device that can be created at an adjustment height with at least one height adjustment with a contact surface for at least one plate.
  • the height adjustment has at least one endless threaded rod and the plate has an assembly opening.
  • a suitability for a bottomless shower cubicle is not listed in the document.
  • German utility model G 93 17 159.5 in turn discloses a support frame for tubs, the frame not only comprising height-adjustable feet, but also swiveling and extending arms. This makes it possible to meet bathtub shapes such as quarter-circle or pentagonal shower trays.
  • the Austrian utility model AT 008 143 U1 describes a fastener for a floor drain.
  • an endless threaded rod can be operated from above, but the fastening element is not part of a substructure system for tubs or plates floor-level shower cubicle.
  • the JP 2002-88839 suggests making the drain body of a drain transparent for inspection purposes or to look for leaks.
  • the EP 0 788 755 A1 discloses a tub support which is cast or foamed from foamed plastic. Before the tub is placed on the tub support, the fitter can provide an assembly and inspection opening designed as a slide in a side wall of the tub support.
  • the object of the present invention is to provide a substructure system for shower cells which largely avoids the disadvantages described above and is optimized with regard to its later properties in the assembled operating state, but also with regard to its ability to be installed.
  • the solution to the problem consists first of all in the arrangement of a shower cell substructure system with a height-adjustable support device with support surfaces on which a support plate or a shower base plate or both can be placed.
  • the height adjustment of the substructure system is designed to be more stable than in the case of known support devices and, at the same time, is designed in such a way that it can still be operated from above through at least one mounting hole or through at least one assembly or inspection opening in the plate or the plates, even when the plate or plates are in place.
  • This assembly or inspection opening in the support plate is arranged approximately in the center or offset to its edge and is designed and dimensioned such that during assembly, with the support plate already in place or pre-assembled, the height of the upper edge of the support plate corresponds to the height of the upper edge of the sub-floor or screed or finished floor can be set flush.
  • This is guaranteed according to the invention in that the elements with which the height can be adjusted - for example with threaded feet - are accessible through the mounting or inspection opening when the support plate is in place. This gives the essential advantage that no previous measurements and any test placements of the support plate have to be carried out. Leakage checks can also be carried out on the drainage system, both during assembly and during later operation.
  • the support plate can optionally represent the shower base plate to be tiled later, or a separate shower base plate can be placed on the support plate and fastened, which can be adapted in the same way to the height of the upper edge of the underlay or screed or finished floor.
  • a further embodiment variant according to the invention provides that the support frame is integrated in the support plate, which is also the top shower base plate or in the support plate, on which a separate shower base plate is placed.
  • the support plate or the shower base plate itself forms the frame on which the elements with which the height can be adjusted are arranged, or other fastening and positioning elements according to the invention, which are described below to be discribed.
  • the support plate or the shower base plate preferably has an underside, which is flat and corresponds to the horizontal in the assembled state.
  • the top of the support plate or the shower base plate is preferably equipped with at least one surface that is at an angle to the horizontal.
  • a single surface forms an inclined plane on which the water flows into a laterally arranged shower channel or into a drain housing.
  • Another possible embodiment variant forms the slopes described in the shower base plate itself, be it whether the support device consists of a support plate, which is preferably planar in this case, and a shower base plate placed on top or only a shower base plate.
  • the support plate forms the required slope and the shower base plate can thus be a normal, flat on both sides (top and bottom parallel to each other).
  • design variants are also feasible in which an overall gradient results from the addition of a support plate gradient and a shower base slab results.
  • a further design variant of the support plate or the shower base plate provides a normal, uniformly strong plate, which, however, is inclined as a whole by means of supports of different heights - preferably integrated in the support plate or shower base plate.
  • This embodiment variant or else one in which the underside of the support plate or the shower base plate forms at least two inclined surfaces, so that the cross section of the support plate tapers approximately in the middle, can be advantageous with regard to a free arrangement of the drainage system.
  • design variants of the support plate or the shower base plate disclose an underside lying horizontally in the assembled state or at least supports which form horizontally lying contact surfaces in the assembled state.
  • design variants of support plates or shower base plates are also hereby disclosed in which the underside or the support surfaces are inclined or concave and this results in more extensive and more powerful adjustment options, for example with threaded feet, which are preferably both on their lower and on their upper Stand in ball joints at the end.
  • an inexpensive variant of a substructure system can be easily implemented, in which only a single direction of inclination towards a laterally arranged shower channel or a laterally arranged drain housing is provided. Due to the fact that the ball joints hold the support plate or the shower base plate at the side, a conventional plate that is flat on both sides can be raised or raised on one side without an integrated gradient. Basically, the same effect can also be achieved with threaded mounts or holders for the threaded feet that the desired Have inclination angles from the outset. This means that the threaded feet are inclined when the support plate or shower base plate is horizontal.
  • the support device preferably has a plurality of height adjustments or novel thread feet, each of which is height-adjustable with an endless threaded rod.
  • the endless threaded rods are in shoes or relatively flat buffer disks, which are preferably made of a soft and low-noise material - for example rubber.
  • the endless threaded rod is preferably mounted in the shoe with a ball joint, so that rotations of the endless threaded rod are not stopped early by contact friction of the shoe on the in-situ concrete. It is equipped with a square or key holder for easy rotation of the endless threaded rod.
  • the key holder can in principle also be arranged on the upper head of the endless threaded rod, for example for an Allen key or Torx key, and can be reached through a correspondingly positioned mounting hole in the support plate and / or the shower base plate.
  • these so-called endless threaded rods have the decisive advantage over arrangements from the prior art that they are significantly larger Operate the adjustment height.
  • the arrangements according to the prior art namely disclose a threaded rod which is fixed with its upper end fixed below the desired support point in the supporting frame and thus provides height adjustability which results solely from how far a threaded foot can be screwed down from the fixed threaded rod without the thread foot becomes unstable.
  • the maximum screw-on dimension can at best be equal to the total height of the neck of the threaded foot minus the height of a threaded foot nut.
  • the height adjustability of a support frame according to the invention is realized differently in that on the one hand the (endless) threaded rod is arranged offset next to the support surface of the support frame or the support device and on the other hand the overall length of the support frame or the support device clearly exceeds.
  • it is not a threaded foot with a nut that is rotated on a fixedly arranged threaded rod, but rather the (endless) threaded rod in a fixedly arranged nut. Or also in a thread that is cut directly into a hole in the bracket.
  • a screwed base foot is present, quasi in accordance with the state of the art, which, however, remains screwed in as far as possible and is not used for height adjustment.
  • the base foot can therefore be designed to be significantly flatter than a buffer disk.
  • the upper attachment point or rather the force application point of the threaded foot 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 nut fixedly arranged on this holder.
  • the upper force application point of the threaded foot according to the invention thus moves over its entire length due to rotations of the endless threaded rod.
  • the height adjustment according to the invention is thus characterized by a significantly greater adjustability with greater stability, because by placing the upper force application point in the fixed nut on the holder (and no longer in a nut arranged in the threaded base itself), only two force application points occur .
  • the upper force application point is the nut itself or the bracket and the lower force application point is the lower end of the endless threaded rod.
  • the endless threaded rod can be locked with a lock nut to the fixed nut or the threaded hole. Then the protruding length of the endless threaded rod capped with a cutting disc or special pliers.
  • the endless threaded rods are preferably available from the outset in a length that guarantees an adjustment height for the maximum usual floor or screed thicknesses or more. An exchange or even a subsequent delivery of threaded rods, even with underlay or screed thicknesses, which are the usual maximum, is excluded from the outset.
  • the endless threaded rod is preferably made of a plastic that has a low sound transmission, in any case less than steel.
  • the plastic of the endless threaded rods is preferably glass or carbon fiber reinforced.
  • the endless threaded rod is arranged in the direction of its upper end in a holder which is fastened to the supporting frame or the supporting device, for example by being welded, screwed or glued on.
  • the holder can be arranged both on the support frame, but also on the support plate or on the shower base plate.
  • the holder is screwed for receiving the endless threaded rod in a fixed nut, a so-called rivet nut or a threaded sleeve arranged in a press fit, or only in a threaded bore.
  • This holder is L-shaped according to the invention, so that one leg of the L can be attached to a vertical surface of the support frame or the support plate or the shower base plate.
  • the other leg of the L can optionally be arranged flush with the top edge of the support frame or the top edge of the support plate or the top edge of the shower base plate or flush with the bottom edge of the support frame or the bottom edge of the support plate or the bottom edge of the shower base plate. This allows mounting plates of different thicknesses to be attached to the bracket be put on. Even particularly thin ones, which use the cost-intensive material from which they are made sparingly, preferably also with recessed contact surfaces or blind holes or recesses.
  • the holder is quasi double L-shaped as two Ls connected to a web.
  • a mounting plate is also conceivable, which is formed from four Ls and a web connecting them.
  • the four Ls can also be formed into one or more round walls.
  • C-shaped rails are also possible as web supports.
  • This web holder can, like the L-shaped holder described above, be fastened to the support frame, or else directly to the support plate or the shower base plate, by screwing or preferably gluing. In the case of gluing, the adhesive surfaces of the web holder are preferably equipped with holes for better contact of the adhesive.
  • This web holder provides an approximately centrally arranged or fixable nut on the web, a so-called rivet nut or a press-fitted threaded sleeve or at least one threaded bore into which, as before, the endless threaded rod can be screwed.
  • the force application points thus lie in the direct extension of the supporting force that occurs for the support frame, the support plate or the shower base plate. Accordingly, these design variants of a height adjustment according to the invention are further provided according to the invention with a mounting hole which, depending on the arrangement in the support frame, the support plate or the shower base plate, is arranged approximately concentrically with the longitudinal axis of the endless threaded rod.
  • the endless threaded rod can be rotated through this mounting hole, preferably by means of a tool holder for a square or an Allen key or Torx key.
  • the height of the support device can be adjusted to the desired dimension, or, depending on the design, the height of the upper edge of the support plate or the height of the upper edge of the shower base plate by setting at least three, preferably four such height adjustments to the same height level.
  • the mounting hole can then be sealed with a stopper, in particular in the embodiment variant in which the last-described height adjustments are arranged directly on the shower base plate.
  • a further embodiment variant of a height adjustment according to the invention both the height adjustment with the L-shaped holder and the last described one with the web holder - provides for a higher degree of height adjustability by arranging the endless threaded rod in a threaded sleeve.
  • This threaded sleeve has an external thread that can be screwed into the threaded bore or the nut on the respective holder.
  • this threaded sleeve also has a preferably continuous longitudinal bore with an internal thread, into which the endless threaded rod can be screwed.
  • the length addition of the usable thread lengths results in a higher adjustability than only by the endless threaded rod alone.
  • the threaded sleeve can preferably be secured with lock nuts on the external thread in both screw directions, and the endless threaded rod can also preferably be fixed with a lock nut on the lower end face of the threaded sleeve.
  • a lock nut is also possible on the upper face of the threaded sleeve or a so-called grub screw, which is screwed into the internal thread of the threaded sleeve from above and thus fixes the endless threaded rod in the desired height position.
  • the bore for receiving the threaded sleeve in the L-shaped holder or the web holder has a larger diameter than the outer diameter of the external thread of the threaded sleeve.
  • the latter is thus simply inserted into the bore and fixed with at least one nut on the top of the bore and at least one nut on the bottom of the bore.
  • the nuts are preferably each underlaid with a washer and a further washer made of a damping material (for example rubber).
  • the threaded sleeve can also form a fixed collar instead of one of the two nuts which they flange onto the web holder, which collar is preferably formed at the upper end of the threaded sleeve.
  • This fixed collar can preferably be inserted into the web holder, again preferably into a receptacle that no longer allows the threaded sleeve to be positively rotated and thus the remaining nut can be tightened.
  • a configuration variant is further preferred, in which no form-fitting receptacle can produce a possible sound bridge between the threaded sleeve and the web holder, since the fixed collar of the threaded sleeve cannot get direct contact with the inner walls of the web holder.
  • a key holder is preferably arranged on the outer diameter of the threaded sleeve.
  • This key holder is preferably smaller than the outer diameter of the threaded sleeve or smaller than the external thread of the threaded sleeve and narrower than the nut is high. So the nut can be screwed seamlessly over the key holder.
  • the support frame consists of a plurality of support frame elements which can be screwed together.
  • a possible basic shape of a support frame according to the invention it forms a square or other basic geometric shapes, the sides of which each consist of a supporting frame element.
  • a possible design variant of this basic form provides a web or a bridge on at least one side of the support frame.
  • a supporting frame element which previously formed one side of the square, now consists of two shorter supporting frame elements, which are connected to a further supporting frame element above it.
  • the web or the bridge thus forms a recess into which the drain housing or the siphon fits in a space-saving manner.
  • the support frame optionally has further support frame elements which, in addition to the previously described support frame elements, are arranged in a fixed or pivotable manner on a joint. At least one such pivotally arranged support frame element fulfills the function of an additional, central stabilization of the support plate or shower base plate placed on top. The pivotally arranged support frame element thus also fulfills the function of an additional support or support point for the support plate or the shower base plate, which can advantageously be positioned anywhere within its pivoting radius.
  • a further embodiment variant of the support frame connects at least some of the support frame elements or all of the support frame elements with joints. In this way, any basic shapes - depending on the layout of the shower - can be realized.
  • the support frame according to the invention furthermore has at least one adjustment element.
  • a length adjustment is implemented at least between two support frame elements, for example by a threaded bolt with left-hand external thread at one end and right-hand external thread at another end in corresponding internal threads of the so connected Support frame elements can be rotated.
  • this length adjustment can also be implemented with elongated holes or with spacers that can be pushed into one another, which can preferably be fixed with screw fastenings.
  • Another, optional design variant of the support frame according to the invention provides an additional adjustment option to the adjustment option described above by means of the threaded bolt or by means of the elongated holes or by means of the displaceable spacers from only one side of the support frame, but also a thread-assisted directional shift of the complete support frame.
