Definitions

  • the invention relates to a gypsum board in particular plasterboard or gypsum fiber board comprising a core of porous gypsum-containing material, a gypsum composite or gypsum and cover layers of cardboard or glass fiber fabric at least on both sides of the gypsum board, of which a first defines a visible side and the second side a back for forming a stable and inherently rigid composite, wherein the gypsum board has two flattened longitudinal edges running parallel to one another to form a filling section, and at least two end edges extending transversely to the longitudinal edges, at least one end edge of which is also flattened and forms a filling section; and a method for producing a gypsum board.
  • plasterboard or gypsum fiber board comprising a core of porous gypsum-containing material, a gypsum composite or gypsum and cover layers of cardboard or glass fiber fabric at least on both sides of the gypsum board,
  • Plasterboard panels are often used today for interior fittings, be it as wall or ceiling panels. There is a desire to make the transition between two abutting plasterboard optically inconspicuous. In this context, it is already known to provide Verspachtelungsabête on the gypsum board in the region of their lateral edges on the visible side, in which the gypsum board following a given contour flattening to the side facing the longitudinal or end edges. If two plasterboard panels provided with such flats are placed against each other, a slight depression forms, which can subsequently be filled with filler. By filling a smooth transition between two adjacent plasterboard can be created without a shock or a joint occurs.
  • Gypsum boards are, however, produced in a continuous process, ie molded as a strand. Therefore, only two opposite, parallel longitudinal edges within this continuous molding process be flattened. On the other hand, the transverse edges extending transversely thereto can not readily be formed in this continuous molding process.
  • the object of the present invention is therefore to design a flattening at the end edges in such a way that the setting of a reliable screw connection becomes possible.
  • the residual cavity of the groove remaining after depression of the filling section is filled with a filling comprising two components, namely a filling material and a bond, the filling being filled out low-shrinkage, volume-stiff, highly filled organic and / or mineral bound filler material, such that after hardening substantially void-free and a screw-fitting resistant filling formed.
  • a filling comprising two components, namely a filling material and a bond
  • the filling being filled out low-shrinkage, volume-stiff, highly filled organic and / or mineral bound filler material, such that after hardening substantially void-free and a screw-fitting resistant filling formed.
  • the two components of the backfilling namely the filling material and the bond
  • the two components of the backfilling are arranged separately, but if necessary, arranged in mixing areas between the core residual section and cover layer.
  • the distribution of filling material or bonding material within the filling area can be optimized such that either volume-stable, highly filled filling areas or adhesive and, in particular, rapidly setting areas can be provided at the respectively suitable locations.
  • the adhesive for bonding is preferably thermally activated in contrast to the filler.
  • the adhesive used is preferably dispersion adhesive.
  • the filling material is provided or arranged facing away from the end edges or longitudinal edges.
  • the bonding is initially provided in the end edges or longitudinal edges facing areas of the backfilling, such that the core remnant portion and cover layer are permanently fixed to each other edge over the bond. This results in a "locking effect" by the bond in the front groove area.
  • the filling material fills the filling area so that no or only minimal voids are created between the bond and the filling material.
  • the low-shrinkage, volume-stable, highly filled organic and / or mineral-bonded filler material has a setting time of> 10 min.
  • the bond comprises a fast-acting adhesive component.
  • the adhesive component is effective in the range of 5 to 60 seconds, preferably in the range of 15 to 25 seconds.
  • a second core residual section remains, which has a thickness that is significantly smaller than the thickness of the first core residual section.
  • This second core remnant section is formed automatically when the groove can not be placed arbitrarily close to the covering layer of the visible side.
  • a core remnant portion can add stability to the paperboard cover layer.
  • this second core remnant section can have, for example, a thickness of approximately 1 mm.
  • a combination of bonding on the one hand which causes a holding effect, and a backfilling with gypsum on the other.
  • This combination causes a largely shrinkage of backfilling.
  • the bonding is preferably carried out by thermal activation on both sides, ie a thermal activation of the first, upper groove flank and the second, lower groove flank.
  • the groove can have a substantially rectangular cross-sectional shape or, which is also claimed independently in accordance with the invention, a shape which tapers in the depth.
  • the size of the groove is preferred about 40 x 2.3 mm 2 to 40 x 2.5 mm 2 .
  • a contour can be selected which corresponds to the contour of the flattening to be achieved, so that only very little or no filling material is required for backfilling the groove, but a conventional one for fixing in this variant Adhesive may be sufficient.
  • the cover layer is raised together with an associated second core remnant section and held in this position for a predetermined time. It has been shown that an advantageous period of time for holding the cover layer together with the associated second core remnant section is between 2 and 10 seconds.
  • a piercing into the region of the now expanded groove takes place in order to reduce the restoring force of the cover layer together with an optionally present second core remnant section.
  • the piercing can be done by a tool with a sharp point in the fracture area of the plasterboard.
  • a cut is made along the innermost end of the groove.
  • a depth of between 0.5 and 3 millimeters is advantageous.
  • the Nachstechen which is also referred to as regrooving, facilitates cleaning, gluing and filling with plaster, especially in the area facing away from the front edges area.
  • the combination of raising the cover layer of the groove, holding the cover layer in this position for a predetermined time and a piercing in the region of the enlarged groove is particularly advantageous and is also referred to as relaxation cut, as this effectively reduces the tension between the cover layer and the first core remnant section can be. On the one hand, this facilitates backfilling, but it also reduces additional restoring forces when closing the groove later.
  • the backfilling of the groove and the compression of the remaining front ends with a pressing tool in an inline process ie within the production process of the plasterboard, and the curing done the filling material is made after ejection of the gypsum board from the inline process without further pressing tools or externally attacking shape retaining means.
  • the backfilling of the groove and the compression of the remaining front ends with a pressing tool also be carried out in a separate process, for example by using interposed plasterboard.
  • postforming rollers are preferably used which press the ends together for about 15 seconds.
  • the groove is mounted on a level closer to the visible side than to the rear, such that towards the back the cover layer and a (first) core remnant portion and to the visible side only the cover layer or the cover layer with a second core remnant portion, the one to the thickness of the first core portion has substantially smaller thickness remains.
  • the cover layer of the visible side or the cover layer with a second core remnant portion on the visible side can then be much simpler to form the desired flattening with a pressing tool on the first core remnant portion, so that the desired contour can be formed.
  • the groove is preferably introduced by material removal, in particular by milling and / or sawing, being intended primarily to a substantially rectangular shape of the groove.
  • material removal in particular by milling and / or sawing, being intended primarily to a substantially rectangular shape of the groove.
  • tapered groove cross-sectional shapes in particular a shape of the groove adapted to the desired flattening, can also be formed.
  • a cleaning step is provided after introducing the groove to remove unbound particles, in particular residual dust.
  • This cleaning step may include, for example, purging and / or rinsing. But it is also alternatively or additionally a purely mechanical cleaning, in particular cleaning by brush conceivable.
  • the groove to be filled is treated with primer before introducing the filling material.
  • the primer improves the strength of the fixation of the front ends together. In an alternative embodiment, however, a sufficient strength can be achieved even without additional primer.

  • Fig. 2 is a partial cross-sectional view of one of the gypsum plaster board blank after Fig. 1 formed plasterboard 11 illustrated.
  • the plasterboard 11 after Fig. 2 differs from the plasterboard blank Fig. 1 in that the second core remnant portion 31 is pressed with the overlying portion of the cover layer 14 to form a flattening portion on the first core remnant portion 25 to form a flattening portion 21 with a press tool (not shown).
  • the remaining volume of the groove 27 is filled by means of a backfilling 26, wherein the backfilling consists of low-shrinkage highly filled organic and / or mineral bound filler such that after hardening substantially void-free and a screw fixation enduring filling is formed.
