Definitions

  • the present invention relates to a substructure for a floor covering, in particular for terrace panels, according to the preamble of claim 1.
  • rotatable adjustable feet made of plastic are known, which are height adjustable via a thread and on which a floor covering is supported.
  • the adjustment of the feet is complex and also there is the problem that due to the low weight of the feet of the floor covering can be easily lifted and moved due to wind loads.
  • the EP 1 691 002 discloses a laying system for a floor covering, in which plate-shaped covering elements are placed on a plurality of support beams. At the covering elements means for height adjustment are provided to align the covering elements relative to the supporting beams.
  • the production of such covering elements with integrated height adjustment device is comparatively complicated and also leads to the disadvantage that retaining forces are absorbed only in a vertical direction, since the covering elements can also be stressed and displaced in the horizontal direction.
  • Furthermore, in the height adjustment there is the problem that the screwing of the leveling screws at the different positions of the floor covering takes a relatively long time.
  • the WO 2009/021516 A1 discloses a flooring fixture comprising two wedge-shaped elements. At the lower wedge-shaped element, a protruding rib with teeth is provided, which in a Recording engages the upper wedge element in order to fix it at different heights can.
  • the DE 20 2008 003 464 U1 discloses a height-adjustable floor support for system floors with a first and a second base member which are plugged into each other and rotatable about a common axis.
  • the DE 29 26 488 A1 discloses a height-adjustable support for supporting the upper floor of a double floor with a lower and an upper wedge body.
  • the substructure comprises at least one block which can be placed on a base on which at least one holder for a support beam for supporting the floor covering is arranged, wherein the holder can be attached to the block at different heights.
  • a height compensation can be made in a simple manner by the holder is plugged in the desired height on the block. It is not necessary that over a tedious thread adjustment a fine adjustment takes place, which unnecessarily complicates the assembly.
  • By placing the holder on the block in the desired position effective alignment in both the vertical and horizontal directions can be achieved by moving the block. Especially when laying large-area floor covering thus the orientation of the support beams, on which then the flooring is launched, done in a short time.
  • the holder can be formed one or more parts.
  • the support beam must therefore not be fixed directly to the holder, but can also be indirectly fixed to the holder via other components, for example in order to increase the installation height or to support the support beam resiliently. If such additional components are not used, the support beam can also be fixed to an integrally formed holder.
  • a plurality of receptacles for mounting a holder are formed at different heights on the block.
  • the recordings can be provided along an inclined plane, which is inclined at an angle between 5 ° and 45 °, in particular 10 ° and 30 °, to the horizontal.
  • the holder can be attached in small steps along the inclined plane.
  • the holder is inserted for mounting with one or more projections on one or more receptacles of the block.
  • the projections and the receptacles are designed so that the holder is secured in a mounted on the block position against lifting in the vertical direction. This ensures that the floor covering on the substructure on the one hand is aligned at the correct height and on the other hand can not be lifted easily under a load of the substructure, only if the entire substructure is raised, which is unlikely due to the considerable weight forces for normal use .
  • the receptacles in the block are groove-shaped, wherein the side walls of a groove-shaped receptacle are inclined in the same direction relative to the vertical. Then forms a wall of the groove-shaped receptacle of a stop, which avoids lifting in the vertical direction.
  • the receptacle is undercut with a tapered neck portion to prevent lifting of the retainer from the block.
  • two spaced webs are provided with receptacles for mounting a holder on the block.
  • the support beam can then be positioned at least partially between the two webs with the receptacles, wherein the support beam and the webs are aligned substantially parallel.
  • the holder may have on its upper side a flat bearing surface on which one or more latching webs are provided.
  • the block of the substructure is preferably produced as a cast part, in particular made of concrete.
  • the substructure has a high dead weight, so that lifting by a load on the floor covering can be avoided.
  • At least one spring element is provided on or on the holder for the elastic mounting of the support beam, so that the support beam is resiliently mounted during a weight load.
  • the floor covering can be used, for example, as a sports floor on which ball sports, such as handball or basketball, can be played.
  • On the holder may be provided on the spring element an attachment part on which the support beam is fixed, wherein the attachment part is secured to the holder against lifting. This ensures that the attachment is due to the resilient support by the spring element at a weight load, although lowered down, but lifting, for example, in a suction by high winds, is prevented. This ensures a secure fixing of a floor covering even in stormy weather or under dynamic loads, for example by using the substructure in a sports floor.
  • the spring element is designed as a block of an elastic material, in particular of plastic or rubber.
  • Shore hardness which may for example be in a range between 40 and 100 Shore, the elasticity of the spring element and the bearing of the support beam can be adjusted.
  • a substructure 1 comprises a block 2, which may be made of a casting of concrete, plastic or a mixture thereof, and at least one holder 3, which is attached to the block 2.
  • the holder 3 may be made of plastic, wood or other materials.
  • the block 2 has a bottom plate 5, which can be placed on a substrate, wherein on the bottom plate 5, two spaced apart parallel webs 6 are formed.

  • FIGS. 2A to 2F the substructure 1 is shown in different views, wherein in FIG. 2B an example of a support bar 4 is shown, which is held on the upper holder 3 on the block 2. On the right side of the bottom 2, another holder 3 is plugged out, which is positioned lower by the height ⁇ h than the left holder 3. As a rule, of course, only one holder 3 is mounted on the block 2.
  • the substructure 1 may have a plurality of blocks 2 and holders 3 in the longitudinal direction of the support beam 4, depending on the length of the individual support beams 4 and the expected weight load.
  • a plurality of supporting beams 4 can be arranged parallel to one another and supported by blocks 2 and holders 3.
  • a floor covering is then placed, for example, wooden boards or extruded panels of a mixture of natural fibers and a polymer, which are also known as WPC plates.

Both walls 14 are inclined in the same direction from the vertical, in Figure 2C the upper wall 14 is inclined by the angle ⁇ to the vertical and the two walls 14 are arranged spread apart by the angle ⁇ . As a result, jamming of the holder 3 during assembly is avoided. In addition, it is prevented that the holder 3 can be lifted in the vertical direction of the block 2, but can only be pulled off obliquely upward from the block 2 to disassemble the holder 3. If the support beam 4 and the floor covering are supported on the holder 3, the holder 3 can only be moved together with the block 2 in the vertical direction.
  • the block 2 is shown without a holder 3.
  • the two spaced webs 6 form an inclined plane, at the top of a plurality of receptacles 11 are arranged, in this embodiment six shots 11.
  • the number of shots 11 depending on the height adjustment, for example, between four and ten shots 11.
  • At the Base plate 5 is further formed a recess 12 to mount a holder 3 in the lower region of the webs 6, wherein it is ensured in each case that a bearing surface 20 is disposed at least as high as a top 13 of the bottom plate to the holder 3 5, so that the alignment of the support beams via the holder 3 takes place.
  • the distance between the webs 6 is dimensioned such that a support beam 4 between the two Webs 6 can be positioned, even when the holders 3 are mounted in a lower position on the block 2.
  • the holder 3 has on its upper side a flat support surface 20 with two parallel locking webs 8, between which the support beam 4 can be fixed by clamping or latching.
