Definitions

  • the invention relates to a dry screed system that can be laid on a floor or subsurface according to the preamble of claim 1.
  • the dry screed system therefore comprises a base layer formed from base plates and at least one cover plate layer formed from cover plates.
  • the base plates contain plaster or are formed from plaster.
  • the cover panels contain rigid wood or a rigid wood material or are formed from rigid wood or a rigid wood material.
  • the cover plates can be glued or glued to the base plates.
  • the invention further relates to the use of a dry screed system according to claim 11.
  • the invention also relates to a method for laying a dry screed system according to claim 12, in particular described herein.
  • the invention further relates to an insulation method according to the preamble of claim 13.
  • the invention relates to a dry screed system production method according to the preamble of claim 15.
  • the object underlying the invention is to improve the qualitative properties of a floor or dry screed without additional craftsmanship and without additional costs for materials and logistics.
  • This task is achieved by a dry screed system according to claim 1 that can be laid on a floor or subsurface. Further refinements of the invention result from the subclaims and additional claims.
  • the dry screed system according to the invention is therefore characterized in that on the A positioning aid is arranged on the base plates and / or the cover plates, which is visible when laying out or after laying out the base plates and / or cover plates, and which specifies the position of the cover plates that can be arranged or arranged on the base plates in such a way that there is at least one between the base plate and the cover plate forms an offset, the offset dimension being greater than approximately 20 cm, in particular the offset dimension is in the range of approximately 20 cm to approximately 40 cm, preferably it is approximately 30 cm.
  • an offset in one direction can be provided, or a first offset in a first direction and a second offset in a second second direction, approximately perpendicular to the first direction.
  • the cover plate is preferably made of a rigid wood fiber material, for example a medium-density wood fiber board (MDF).
  • MDF offers the advantage that the material is available with high dimensional stability and is comparatively low in thickness. Despite the low thickness of the top layer and because of the flexural rigidity of the top layer, when laying the dry screed system, the result is a stable and even top layer (ie no or almost no unevenness in the laid dry screed).
  • an MDF cover board according to the invention has a thickness or thickness (for example approx. 2 to approx. 6 mm thickness) with a (manufacturing) tolerance of approx. 0.1 mm over a length (or width) of approx. 1 m This ensures that the surface of the dry screed system is even and that no noticeable joints form during installation. It is therefore not necessary for the dry screed to be primed and/or filled after laying before a floor covering is placed on it.
  • the cover plate can have a thickness of approximately 2 mm to approximately 6 mm, preferably approximately 4 mm. Because the cover plate is comparatively thin, it has a low weight, which reduces the pressure when laying and gluing. A reduced inherent pressure of the cover plate on the base plate ensures that the contact adhesive does not prematurely solidify or harden too early before the plates are aligned/adjusted relative to one another and due to the weight pressure of the cover plate.
  • the base plate can be formed from a gypsum board with a thickness of approximately 6 mm to approximately 20 mm, preferably with a thickness of approximately 10 mm. This ensures that the dry screed is comparatively thin overall - without any loss of stability.
  • the base plates and/or the cover plates are rectangular, preferably in such a way that the length of the long side of the plates is twice the length of the narrow sides of the plates, in particular in such a way that the long sides have a length of approx. 120 cm and the narrow sides are approx. 60 cm wide. If the offset dimension is approx. 30 cm as described above, the offset would correspond to half the width of the narrow sides of the panels. This results in some simplifications when laying the layers:
  • the base plate can be cut to a width of approx. 30 cm using the positioning aid, which specifies a 30 cm distance from the edge of the plate.
  • the positioning aid also has the function of a cutting aid.
  • the panels can therefore have a positioning and cutting aid. These halved-width panels are laid on the edge of the floor/subsurface. Next to it, uncut panels with the specified width of 60 cm are arranged. Uncut cover plates are arranged on the edges, resulting in the offset according to the invention of approx. 30 cm without the need for measurement or adjustment. The craftsman can do this without any additional workmanship by using the positioning aid or positioning/cutting aid for the base panels when laying and cutting the panels.
  • the positioning aid can preferably comprise several positioning marks or positioning and cutting marks that are visibly arranged on the base plate/cover plate.
  • the positioning marks can be arranged in such a way that they are at a distance of approximately 30 cm from the edge of the panel on the narrow side of the panel and/or at a distance of approximately 30 cm from the edge of the panel on the long side of the panel.
  • a plate size of 120 ⁇ 60 cm 2 two positioning marks of the positioning aid would be arranged on the plate, namely both on an imaginary center line between the edges of the long sides and both at a distance of 30 cm from the nearest edge of the narrow side.
  • the distance between the positioning marks is 60 cm.
  • the offset dimension preferably corresponds to half the panel width (for example 60 cm, ie offset dimension in the transverse direction approximately 30 cm).
  • the offset dimension preferably corresponds to a third of the panel length (for example 120 cm, ie the offset dimension in the longitudinal direction is approximately 30 cm).
  • the positioning marks can be printed or pressed or embossed or punched or glued onto one or both sides of the base plates/cover plates.
  • the positioning marks are preferably formed or shaped in a T shape.
  • the horizontal line or structure of the T-shaped marks runs, for example, parallel to the long side of the base plates/cover plates, the vertical line/structure of the T-shaped marks runs, for example, parallel to the narrow side of the base plates/cover plates.
  • the orientation of a T-shaped positioning mark can differ from the orientation of the neighboring positioning mark. This makes cutting and staggering the panels in the corner of the room easier because the orientation of the T-shaped positioning marks also determines the direction of the offset cover panel.
  • an adhesive layer is arranged on the base plate and on the cover plate, the adhesive of the adhesive layers comprising or being formed from a contact adhesive .
  • the contact adhesive is on both parts to be joined arranged, ie on the underside of the cover plate and on the top of the base plate. Unlike wet adhesives or two-component adhesives, the parts to be joined, namely the base plate and the offset cover plate, can be moved relative to one another after contacting the surfaces to which contact adhesive has been applied.
  • the craftsman receives a comparatively thin, easy-to-lay dry screed with a flat and hard surface without unevenness and annoyingly wide joints and with a permanently high level of stability due to the offset.
  • Tensions in the screed are avoided due to the use of the contact adhesive, as is structural failure of the panels and/or the panel connection, since the cover layer is made of a rigid material.
  • Tests have shown that the combination of a rigid, comparatively thin top layer arranged on the Gibs base layer, both glued with a contact adhesive that allows alignment and adjustment, in conjunction with the stabilizing offset of at least 20 cm (in two directions) forms a dry screed, which is overall thinner than comparable systems and at the same time more stable and even, i.e. with fewer unevenness or imperfections in the surface.
  • a removable protective film is arranged on at least one adhesive layer.
  • the protective film When laying, the protective film must then be removed so that the adhesive layer is released can be brought into contact with the other layer.
  • the protective film protects the adhesive layer, for example, from contamination, such as crumbs or other dirt, and also from wear and unwanted volatilization of the adhesive.
  • the base plates and/or the cover plates are formed in multiple layers, in particular in two layers.
  • the additional layer can, for example, comprise or be formed from a thermoplastic, for example polyethylene (PE) or a foam thereof (PE foam) and/or extruded polystyrene (PS) and/or extruded polystyrene (XPS).
  • PE polyethylene
  • PS polystyrene
  • XPS extruded polystyrene
  • the additional layer can alternatively or cumulatively contain a wood fiber material and/or a wood fiber insulation material.
  • the additional layer may alternatively or cumulatively contain coconut fibers, cork and/or straw.
  • dry screed system described herein can be used as impact sound insulation system is used.
  • the impact sound insulation can be arranged, for example, between a subsurface and a parquet floor.
  • An improvement in the qualitative properties of a floor or dry screed without additional craftsmanship and without additional costs for materials and logistics also results from a method for laying a dry screed system according to claim 12, in particular described herein. Accordingly, in a first process step on a Floor or subsurface base plates of the dry screed system are laid. In a second process step, cover panels of the dry screed system are arranged on the base panels. The cover plates are attached to the base plates by means of an on the base plates and/or the positioning aid arranged on the cover plates is arranged offset, so that the offset has an offset dimension of at least approximately 20 cm, in particular approximately 20 cm to approximately 40 cm, preferably approximately 30 cm.
  • the positioning aid can be formed from several positioning marks arranged on the base plates, with the cover plates being placed against the positioning marks of the base plates when being laid.
  • the positioning marks indicate the positions of the joints in the top layer of the dry screed, which do not correspond to the positions of the joints in the base layer.
  • the panels have an offset and the joints between adjacent base panels also have an offset compared to the joints of the cover panels adjacent to one another.
  • the high dimensional accuracy of the cover panels and the possibility of precise positioning of the panels due to the properties of the contact adhesive, the positioning aid and a comparatively low cover panel weight ensure that the joints or joints in the cover layer are very narrow, so that the cover layer of the dry screed is overall flat and has no or almost no unevenness.
  • the cover panels are glued together with the base panels of the dry screed system, namely by contacting a contact adhesive layer of the cover panels of the dry screed system with a contact adhesive layer of the base panels of the dry screed system.
  • the contact adhesive layers are already arranged on the panels, so that no adhesive material needs to be prepared and applied during installation.
  • the contact adhesive layers are particularly easy to handle if at least one protective film of the panels of the dry screed system arranged on at least one of the adhesive layers is removed before laying the cover panels.
  • An improvement in the qualitative properties of a floor or dry screed without additional craftsmanship and without additional costs for materials and logistics is also achieved through an insulation process according to claim 13.
  • the process is used to insulate what is produced on a floor or subsurface Impact sound.
  • the method described here is used for laying a dry screed system, in particular described here.
  • a system construction material includes a cover plate and a base plate.
  • a contact adhesive layer is placed on the base plate.
  • a contact adhesive layer is also arranged on the cover plate.
  • a protective film is placed on the contact adhesive layer of the base plate.
  • the base plate and cover plate are packed one on top of the other and thus form an applicable system construction material.
  • the user/craftsman procures a sufficient number of system construction materials for a room or room, removes the packaging and can lay the panels in a staggered manner, if necessary after the panels have been cut accordingly.
  • the dry screed system 1 shown schematically is used to lay out a dry screed 4 on a floor/substrate 2, for example a room 3.
  • Several system building materials 5 are used, the number of system building materials 5 depends on the size of the floor area 6 of the room 3.
  • One system building material 5 is in Fig. 1 shown schematically and it includes, for example, a base plate 7 and a cover plate 8. It can be provided that the system construction material 5 is packaged in such a way that four plates 7, 8 are contained per packaging, for example two base plates 7 and two cover plates 8 It is sufficient if a protective film 10 of the adhesive layer 9 is only provided on the base plates 7.
  • the system construction materials 5 to be laid can optionally be provided on a (Euro) pallet, ie with a two- or three-digit number of panels 7, 8. If so many panels 7, 8 are stacked on one another for the purpose of packaging, shipping or storage, It is recommended that each of the plates 7, 8 is equipped with a protective film 10, since the pressure acting on the plates 7, 8 can otherwise lead to undesirable sticking of the plates 7, 8 within the packaging.

  • Base plate 7 and cover plate 8 have an area of 60 ⁇ 120 cm 2 .
  • the adhesive layers 9 each comprise a contact adhesive.
  • the craftsman will first remove the base plate 7 and lay it on the floor/substrate 2, then the protective film 10 of the base plate 7, then remove the cover plate 8 from the packaging and peel off the protective film 10 of the cover plate 8 and finally arrange the cover plate 8 offset on the base plate 7 with the help of one or more positioning marks 13 of the positioning means 12 and by contacting the adhesive layers 9 of the Glue plates 7, 8 together.

  • the Figures 2A and 2B show different views of one of the base plates 7 of the dry screed system 1.
  • a positioning aid 12 or positioning and cutting aid 12 is arranged on the surface 11 of the base plates 7.
  • the positioning aid 12 includes two registration or positioning marks 13.
  • the positioning marks 13 are printed on the surface 11 of the base plate 7.
  • Each positioning mark 13 is T-shaped, with the horizontal line 14 of the T-shape being oriented parallel to the edge 15 of the long side 16 of the plate 7, and the vertical line 17 of the T-shape being oriented parallel to the edge 18 of the narrow side 19 of the plate 7
  • Each positioning mark 13 specifies a positioning point 20, namely at the intersection or intersection of the vertical and horizontal lines 14, 17 of the respective T-shape.
  • the orientation of the first positioning mark 13 is mirrored or rotated by 180 ° compared to the orientation of the second positioning mark 13.
  • the first Positioning mark 13 therefore specifies a first positioning direction next to the positioning point 20 and the second positioning mark 13 specifies a second positioning direction opposite to the first positioning direction.
  • the positioning marks 13 not only help the craftsman when laying the dry screed 4 to achieve the offset 21 between the base plate 7 and cover plate 8 of approx. 30 cm, but they also serve as a cutting aid.
  • the (center) line 22, which geometrically intersects the first and second positioning marks 13, helps in cutting the panel width, ie parallel to the panel's longitudinal direction ( Fig. 2A ).
  • the (third) line 23 that runs parallel to the narrow side 19 of the plates 7, 8 and geometrically intersects the first or second positioning mark 13 helps in cutting the length of the plate, that is, parallel to the transverse direction of the plate, which is oriented perpendicular to the longitudinal direction of the plate ( Fig. 2B ).
  • FIG. 3 An arrangement of base plates 7 laid on a floor 2 in a room corner 24 can Fig. 3 be removed.
  • the base plates 7 form the base layer 25.
  • the edge plates 7 have been cut and laid using the positioning marks 13 and uncut base plates 7 have been laid adjacent to them (in Fig. 3 only an uncut base plate 7 is shown, in Fig. 4 several of these plates 7 are shown).

  • the protective film 10 can be removed by the craftsman, which in Fig. 3 is shown schematically by the arrow symbols. After removing the protective film 10, the cover plates 8 can be arranged on the base plates 7.
  • the cover plates 8, which form the cover plate layer 26, are laid in such a way that a corner of the cover plate 8 is positioned on a positioning mark 13, in particular on the positioning point 20. This always results in an offset 21 of approximately 30 cm relative to the longitudinal edge 16 and relative to the narrow edge 18 of the base plates 7. As in Fig. 4 shown, some of the edge cover panels 8 also need to be cut. If the cover plates 8 also have positioning marks 13, these can also help with cutting the cover plates 8.
  • the cover plates 8 are glued to the base plates 7; for this purpose, the base plate 7 and cover plate 8 each have a contact adhesive layer 9.
  • the combination of base and cover plates 7, 8 with bonding (9) and offset 21 creates a stable and at the same time sufficiently flexible dry screed 4.
  • Dry screed 4 shown schematically can also be used as impact sound protection.
  • a particularly good impact sound protection is created if, for example, the base plate 7 is formed in multiple layers and includes an additional layer made of a PE foam (not shown in the Figures 1 to 4 ).
