Definitions

  • the present invention relates to a modified OSB board according to claim 1, a construction wall for a house building system according to claim 5, a partition wall for a house building system according to claim 11 and a house building system according to claim 14.
  • OSB boards are wood-based boards which are obtained from strands.
  • the OSB boards are more and more used in wood and prefabricated house building since OSB boards are of a light weight but still fulfil the static requirements of construction boards or panels.
  • OSB boards are used as construction panels and as wall or roof plating or also as flooring panels.
  • the production of OSB boards is carried out in a multiple stage process, wherein at first the strands are cut from debarked woods, preferably soft woods, in longitudinal direction by rotation blades. In the subsequent drying process the natural humidity of the strands is reduced at high temperatures. The degree of humidity of the strands can vary depending on the adhesive used. Following the drying process the strands are feed into a gluing apparatus, in which the glue or is applied to the strands. PMDI (Polymeric Diphenylmethandiisocyanate) or MUPF resin (Melamine Urea Phenol Formaldehyde) are mainly used as adhesives.
  • PMDI Polymeric Diphenylmethandiisocyanate
  • MUPF resin Melamine Urea Phenol Formaldehyde
  • the glued strands are spread alternating lengthwise and crosswise to the production direction such that the strands are arranged crosswise in at least three layers (lower layer, middle layer, upper layer). This is followed by a continuous pressing of the strands at high pressure and high temperature.
  • OSB boards can be used as construction panels in particular in the prefabricated house construction.
  • the wall is made of a solid wood frame filled with appropriate beams (in particular i-beams) and covered from both sides with the OSB boards. The space between the frame elements is isolated.
  • OSB Boards may also be provided with a paper layer arranged thereon ( DE 10 2005 021 156 A1 ).
  • a resin layer with a thickness of about 5 ⁇ m is arranged in the upper side of the paper layer. This allows the production of a multiple layer board with a very glossy surface.
  • plaster board panels typically cover the side of the construction wall pointing to the inner side of the house or building.
  • plaster boards When using plaster boards, a large number of accessories, like screws, reinforcing mashes and a large amount of plaster mix is required, which has to be applied in layers over a large area at the junction of the plaster board panels. In addition, the spots or spaces, where screws are driven into the plaster board panel need to be filled. Furthermore, after application of each layer one has to wait until the plaster is dried, then the surface has to be abraded before the next layer is applied. These operations generate large amounts of gypsum dust and lengthen the time for the installation of the finishing trims.
  • the structure of plaster board panels is also soft and is not suitable for hanging up heavier decorations such as large paintings. Thus, in order to hang up decorations on such a plaster board panel the construction has to be strengthened or special mounting dowels need to be used.
  • gypsum fiber boards are typically very heavy (density of about 1200 kg/m 3 ) and require a lot of effort and knowledge on the part of the person fitting them.
  • special accessories which are only used for gypsum boards, like Fermacell gypsum board are used.
  • the surface requires the application of a gypsum coat over the entire area.
  • special tools are required for cutting and machining operations.
  • the object of the present invention is thus to overcome the disadvantages of the presently used gypsum boards. This object is being solved by a modified OSB board according to claim 1.
  • a modified OSB board with an upper and a lower side whereby the upper and/or lower side of the OSB board are coated with at least at least two paper layers and wherein the paper layer being adjacent to the board surface as first paper layer is impregnated with at least one resin, and wherein the second paper layer arranged on the first paper layer is a raw paper layer, wherein the weight of the raw paper is between 100 and 300 g/m 2 .
  • the upper and lower side are each coated with at least two paper layers.
  • modified OSB board can be used as an alternative to the gypsum boards.
  • the physical and mechanical properties of the modified OSB board allow an installation of heavy elements of interior finishing without special dowels.
  • the modified OSB boards can be linked together in an easy manner using a specific plate connection system (a tongue and groove joint system) which allows for hiding the screw heads.
  • a specific plate connection system a tongue and groove joint system
  • adhesives such as polyurethane adhesives ensures a strong and durable bonding of the modified OSB boards.
  • Said connection system does not require the use of large amounts of gypsum only one layer is sufficient to fill the connections.
  • the outer layer of the modified OSB board can be used without further priming for painting or wallpapering. Altogether, fewer steps are required for installing the modified OSB board and thus time and investment costs are reduced. Another advantage is to apply plaster to coat the modified OSB board with acrylic paints or to stick wallpapers to the modified OSB board. Specially designed finishing with tongue and groove allows the installation of the panels without any efforts even by persons with no professional skills.
  • the modified OSB board has a thickness in the range between 5 to 50 mm, preferably between 7 and 30 mm, in particular preferably between 9 and 22 mm.
  • the one first paper layer i.e. the paper layer being adjacent to the board surface (i.e. the first paper layer is arranged directly on the OSB board surface) is impregnated with at least one resin, in particular at least one formaldehyde resin.
  • the formaldehyde resin used for impregnation of the first paper layer is selected from a group comprising melamine formaldehyde resin, urea formaldehyde resin and melamine urea formaldehyde resin or maleic resins or urea-maleic-formaldehyde resin.
  • the first paper layer consists of a paper with a weight in the range between 30 and 200 g/m 2 , preferably between 50 and 150 g/m 2 , in particular preferably between 80 and 120 g/m 2 .
  • the second paper layer i.e. the paper layer arranged on the first paper layer, consists of a raw paper.
  • the weight of the raw paper used for the second paper layer is in a range between 100 and 300 g/m 2 , preferably between 100 and 250 g/m 2 , in particular preferably between 100 and 120 g/m 2 .

  • the paper layers and here, again, in particular the second outermost paper layer, is pressed with a layer of a metal film such an aluminum film for heat reflection.

  • the present modified OSB boards can be provided in form of panels with sharp edges or as panels with a tongue-and-groove joint.
  • the use of a tongue-and-groove joint for each OSB board is however preferred.

  • a construction wall for a house building system comprises at least one modified OSB board as described previously.
  • the construction wall comprises
  • the wood frame of the present construction wall may be a solid wood frame.
  • the use of solid wood in the structure of the frame does not always meet the requirements of the required construction quality since the beams made of solid wood are often uneven, twisted and have knots. As a result, a lot of expensive waste timber is created which in turn increases the cost and time of the element, such as the construction wall, being built.
  • the frame is preferably made of a wood based material (OSB power).
  • the wood-like material is characterized by physical and mechanical parameters, which are comparable to solid wood and without the stresses and knots typical for natural wood.
