Definitions

  • the present invention relates to a substructure system, as it finds use 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 support frame allows a suitable setting of the shower floor to be tiled later, at the same time facilitated installation and adaptation of the drain or siphon.
  • the different materials that are used in conventional substructure systems have different material densities and properties, especially in terms of 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, what plates and Joint damage or leaks may result.
  • Another disadvantage is the fact that the known substructure systems no longer allow subsequent leakage control of the drain or siphon, either directly after completion of assembly, or later during operation. After the previously described laying or casting of a gradient concrete or the compaction of the underbody granules, the drain or the siphon are no longer accessible.
  • a further disadvantage is that the concrete, the mortar and the granule binder require drying times, postpone the follow-up work and overall represent an extension compared to modern dry construction with short construction periods and minimized execution risk according to current professional knowledge and expected professional responsibility.
  • floor-level showers are also realized with shower floor elements.
  • These shower floor elements are predominantly foam boards with an integrated slope, which are coated with a Dichtschlämme 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 takes place before the shower floor element is set.
  • the drainage channel or a drainage housing or siphon is connected via a socket, pluggable or screwed.
  • Foam boards are also not stable against mechanical stresses and are subject in new condition as well as with the aging of a sometimes considerable shrinkage, which in turn can cause plate and joint damage.
  • 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 takes place by placing additional foam boards of variable thicknesses or by underfilling with granules, sand or similar. A high level of effort once achieved can hardly be corrected afterwards, which is necessary, for example, when renovating ceramic floor tiles or tiles of a different thickness than previously used.
  • the open-cell foam structure does not allow the installation of inspection openings.
  • the cutting of recesses or generally a subsequent, mechanical processing is not possible, because this would damage the reinforcement or the encapsulation of the foam sheets.
  • the foam boards are thus made in advance according to the predetermined fixed dimensions.
  • the gutter or the drain housing must be installed before laying the shower floor element in this or parts thereof.
  • the siphon and the drain pipe are mandatory before positioning the shower floor element mass to position and secure against displacement.
  • the prior art also discloses combinations of support frame with shower floor elements, in which the support frame is height adjustable by means of threaded legs.
  • the support frame is height adjustable by means of threaded legs.
  • the installation of the support frame on which after setting the previously measured height rate, the shower floor element is placed.
  • the connection of the water outlet via the shower channel and the drain body is again via a sleeve.
  • the installation height of floor-level showers depends on the height of the base or screed and usually varies between 40 and 300 mm. Covering this entire 260 mm adjustment span may not always be guaranteed by the roots or at least not economical so it may be disadvantageous to have to provide thread roots that match the specific local conditions. In addition, this circumstance represents a possible source of error.
  • the gutter or drain housing must be installed before laying the shower floor element in this.
  • the water-conducting connection of the drainage channel and the drainage housing to the siphon is also again via a sleeve.
  • the siphon and the drain pipe are to be positioned accurately before laying the shower floor element and secured against displacement.
  • the object of the present invention is to provide a substructure system which largely avoids the disadvantages described above and is optimized with respect to its later properties in the assembled operating state, but also with regard to its mountability.
  • the solution of the problem consists initially in the arrangement of a substructure system of a height-adjustable support frame and a support plate having at least one mounting or inspection opening.
  • This mounting or inspection opening in the support plate is approximately centrally arranged or offset to its edge and designed and dimensioned so that when mounting, with already aufgoriter or pre-mounted support plate, the height of the upper edge of the support plate to the height of the upper edge the subfloor floor or screed or finished floor can be adjusted flush.
  • This is inventively ensured by the elements, with where the height is adjustable - for example, with threaded feet - are accessible when the support plate by the mounting or inspection opening. This provides the significant advantage that no previous measurements and any trial grounds the support plate must be made. In addition, tightness checks on the drainage system are feasible, both during assembly and during later operation.
  • the support plate can optionally itself represent the shower floor plate to be tiled later on, or a separate shower floor panel can be placed on it and fixed, which can be adapted in the same way to the height of the upper edge of the underlay floor 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 at the same time is the uppermost shower floor panel or in the support panel 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 forms the frame on which the elements are arranged, with which the height is adjustable, or other inventive fastening and positioning elements, which in the following to be discribed.
  • the support plate or the shower base plate preferably has an underside, which is designed plan and corresponds in the mounted state of the horizontal.
  • the top of the support plate or the shower bottom plate is preferably provided with at least one surface which is at an angle to the horizontal.
  • a single surface forms an inclined plane at which the water drains into a laterally arranged shower channel or into a drain housing.
  • two surfaces can run toward an approximately centrally placed shower channel or a drainage housing or, for example, four surfaces for an approximately centered or also to an eccentrically arranged outflow. These surfaces can have congruent or different basic shapes.
  • Another possible embodiment variant forms the described Gesocils Siegen in the shower tray plate 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 base plate.
  • a further embodiment 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 different heights-preferably integrated into the support plate or shower base plate.
  • This embodiment variant or even 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, may be advantageous in terms of a free arrangement of the drainage system.
  • support plate or the shower base plate described so far reveal a bottom lying in the mounted state or at least supports which form horizontal support surfaces in the mounted state.
  • embodiments of support plates or shower base plates are hereby disclosed, in which the underside or the bearing surfaces are inclined or concave and thereby result in more extensive and more powerful adjustment options, for example with threaded feet, preferably both at its lower, and at its upper End in ball joints stand.
  • 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 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.
  • the same effect can also be achieved with threaded sockets or holders for the thread legs, which provide the desired Inclined angle from the outset. This means that the thread roots are inclined at a horizontal position of the support plate or the shower base plate.
  • 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.
  • the endless threaded rods are in shoes or relatively flat buffer discs, which are preferably made of a soft and little sound-transmitting material - for example made of rubber.
  • 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 early by a contact friction of the shoe on the concrete.
  • it is equipped with a square g..einer key holder.
  • the key receptacle 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 be accessible by a correspondingly positioned mounting hole in the support plate and / or the shower base plate.
  • these so-called endless threaded rods are in contrast to arrangements from the prior art the decisive advantage that they serve a much larger setting height.
  • 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 the support frame and thus results in 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 becomes unstable.
  • 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 height adjustability of a support frame according to the invention is realized differently insofar as 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 projects clearly beyond the support frame or support device in their overall length.
  • a threaded foot is rotated with a nut on a fixed threaded rod, but the (endless) threaded rod in a fixed nut arranged. Or in a thread, that is cut directly into a hole in the holder.
  • 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 maximum 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 force application point 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 holder nut.
  • the upper force application point of the thread root according to the invention thus moves through rotations 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 only by the laying of the upper force application point in the fixed nut on the holder (and no longer arranged in the thread root itself mother) 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.
  • the endless threaded rod After setting the required height, the endless threaded rod can be detected with a lock nut to the fixed nut or threaded hole become. Subsequently, the protruding length of the endless threaded rod is cut with a cutting disc or special pliers.
  • the endless threaded rods are preferably available from the outset in a length with which an adjustment height for the maximum usual underlay floor or screed thicknesses or more is guaranteed. A replacement or even a subsequent delivery of threaded rods, even with underlay floor or screed strengths, which are the usual maximum, is therefore excluded from the outset.
  • the endless threaded rod is preferably made of a plastic which has a low sound transmission, in any case a lower than steel.
  • the plastic of the endless threaded rods is preferably glass or carbon fiber reinforced.
  • the endless threaded rod is, as already described above, arranged in the direction of its upper end in a holder which is attached to the support frame or the support device, for example, by being welded, screwed or glued.
  • 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 fixedly arranged nut, a so-called rivet nut or a press-fitted threaded sleeve or even in a threaded hole.
  • This holder is designed according to the invention L-shaped, so that a leg of the Ls on a vertical surface of the support frame or the support plate or the shower base plate can be fastened.
  • the other leg of the Ls can optionally be placed flush with the upper edge of the support frame or the upper edge of the support plate or the upper edge of the shower base plate or flush with the lower edge of the support frame or the lower edge of the support plate or the lower edge of the shower base plate.
  • Different thicknesses of support plates can be placed on the holder. Also particularly thin, which are economical with the expensive material from which they are made, preferably additionally with recessed bearing surfaces or blind holes or recesses.
  • the holder is formed almost double L-shaped as two connected to a web Ls.
  • a mounting plate which is formed of four Ls and a connecting web.
  • the four Ls may also be formed into one or more round walls.
  • C-profile rails are possible as a bar support.
  • This web support can, like the previously described L-shaped bracket also be attached to the support frame, or even directly to the support plate or the shower base plate by being screwed or preferably glued. In the case of a bond, the adhesive surfaces of the web support are preferably equipped with holes for a better contact of the adhesive.
  • This web support provides an approximately centered on the web fixed or fixable arranged mother, a so-called rivet nut or a press-fitted threaded sleeve or at least one threaded hole, in which, as before, the endless threaded rod can be screwed.
  • the force application points thus come, in contrast to the above-described L-shaped bracket in the direct extension of the supporting force occurring for the support frame, the support plate or the shower base plate to lie.
  • these embodiments of a height adjustment according to the invention are further provided according to the invention with a mounting hole, which is arranged depending on the arrangement in the support frame, the support plate or the shower base plate approximately concentric with the longitudinal axis of the endless threaded rod.
  • the endless threaded rod can be rotated, preferably by means of a Tool holder for a square or Allen key or Torx key.
  • the height of the support device to the desired level is adjustable, or depending on the height of the upper edge of the support plate or the height of the upper edge of the shower base plate by at least three, preferably four such height adjustments are set to the same height level.
  • the mounting hole can be sealed with a stopper, especially in those embodiment variant in which the last-described height adjustments are placed directly on the shower base plate.
  • a still further embodiment variant of a height adjustment - both the height adjustment with the L-shaped bracket, as well as the last described with the web holder - provides a higher level of height adjustability by the endless threaded rod is arranged in a threaded sleeve.
  • This threaded sleeve has an external thread which can be screwed into the threaded hole or the nut on the respective holder.
  • this threaded sleeve also has a preferably continuous longitudinal bore with internal thread into which the endless threaded rod can be screwed. Due to the length addition of the so usable thread lengths creates 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 directions of screwing and also the endless threaded rod can preferably be fixed with a lock nut on the lower end side of the threaded sleeve. Equally, however, a lock nut on the upper end side of the threaded sleeve is possible or else a so-called grub screw, which is screwed from above into the internal thread of the threaded sleeve and thus fixes the endless threaded rod in the desired height position.
  • a still further embodiment variant of the last-described height adjustment with an endless threaded rod in a threaded sleeve pursues an additional optimization of the sound decoupling.
  • the bore for receiving the threaded sleeve in the L-shaped bracket or the web support 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 at the top of the bore and at least one nut at the bottom 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.
  • 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.
  • a key receptacle is preferably arranged on the outer diameter of the threaded sleeve.
  • This key receptacle 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. This allows the nut to be screwed seamlessly over the key holder.
  • the support frame according to the invention consists of several support frame elements which are screwed together. According to one possible basic form of a support frame according to the invention, it forms a square or other basic geometric shapes whose sides each consist of a support frame element.
  • One possible embodiment variant of this basic form provides for a web or a bridge on at least one side of the support frame.
  • a support frame element which has hitherto formed one side of the square, now consists of two shorter support frame elements, which are connected to an overlying further support frame element.
