Definitions

  • the invention relates to a planar panel and a method for producing such a panel.
  • Walls for buildings are known in various forms from the state of the art. These can, for example, be formed by stacking and joining several stones. Walls can also be formed by poured and hardened concrete. In addition, flat wall panels made of wood are known that form a wall and can be joined together.
  • an insulating layer In order to form a housing wall that complies with the thermal conductivity regulations, an insulating layer must be attached to the wall.
  • An object of an embodiment of the invention is to propose a planar panel for forming a wall of a housing and a method for producing such a panel, with which a wall of a building can be assembled more time-efficiently.
  • planar panel for forming a wall of a building which comprises at least one wall body formed from a cured rigid foam and which comprises at least one reinforcement arranged within the cured rigid foam and which has at least one reinforcing means formed entirely or at least in sections from a filament yarn textile.
  • the flat panel is made of a hardened rigid foam and also contains reinforcement within the hardened rigid foam, the load-bearing capacity of the panel and thermal insulation can be achieved in a single component. This means that the assembly for forming a wall of a building can be designed in a time-efficient manner.
  • the panel can have a thermal conductivity group 023.
  • the panel may comprise a wall panel, ceiling panel, floor panel and/or roof panel.
  • a wall is understood to mean a side wall, a floor, a ceiling or a roof element
  • the wall includes a ceiling on one floor, this ceiling can simultaneously form a floor on the next floor.
  • the at least one reinforcement means can in principle be designed in any way desired.
  • Embodiments of the panel are preferred in which at least one of the at least one reinforcement means comprises a fibrous reinforcement element or a rod-shaped reinforcement element and/or in which at least one of the at least one reinforcement means is designed to be flat and comprises a filament yarn textile mat or filament yarn textile grid having a plurality of fibrous reinforcement elements and/or a plurality of rod-shaped reinforcement elements.
  • the reinforcement comprises a fibrous reinforcement element or a rod-shaped reinforcement element, this can be easily arranged in sections of the panel which are difficult to access and in which, in particular, no planar reinforcement element can be arranged.
  • At least one of the at least one reinforcing means comprises a filament yarn textile mat or a filament yarn textile grid
  • the reinforcing means can be quickly provided over a large section of the panel, in particular the wall body.
  • the panel makes it possible to retrofit existing buildings by arranging the panel on existing walls. This can improve the insulation of the wall.
  • a wall can also be formed by just one panel.
  • the panel can run in a vertical plane, i.e. enclose an external or internal wall, or run in a horizontal plane, i.e. enclose a floor and/or a ceiling.
  • embodiments of the panel comprise at least one continuous recess in the wall body extending in the width direction of the wall body and at least one frame-like reinforcement unit which is arranged in the wall body adjacent to the recess and which is formed to extend entirely or at least partially around the recess.
  • the continuous recess extending in the width direction of the wall body is completely surrounded by the wall body or if the continuous recess extending in the width direction of the wall body is accessible from the outside at least on one side in the longitudinal direction and/or in the vertical direction.
  • the recess is completely surrounded by the wall body, i.e. the recess is completely framed by the wall body, as well as embodiments in which the recess is accessible from the outside from at least one side. On these sides, the recess is then not limited by the wall body.
  • the wall body which completely surrounds a continuous recess extending in the width direction, at its narrowest point between the recess and the outer edge has an extension of at least 5 cm, in particular of at least 10 cm.
  • the reinforcement unit can basically be designed in any way. It proves to be advantageous if the reinforcement unit comprises at least one reinforcement means which comprises a fibrous reinforcement element or a rod-shaped reinforcement element and/or if at least one of the at least one reinforcement means is designed to be flat and comprises a filament yarn textile mat or filament yarn textile grid having a plurality of fibrous reinforcement elements and/or a plurality of rod-shaped reinforcement elements.
  • the filament yarn textile of the reinforcement element and/or the reinforcing element is made of basalt and forms a basalt fiber textile and/or that the cured rigid foam comprises a polyisocyanurate rigid foam (PIR) or a polyurethane foam (PUR).
  • PIR polyisocyanurate rigid foam
  • PUR polyurethane foam
  • thermo conductivity assembly 023 By choosing PIR or PUR, a material of the thermal conductivity assembly 023 is provided, which in combination with the reinforcement can simultaneously form a wall.
  • the reinforcement comprises only a single reinforcement element.
  • the stability and load-bearing capacity of the panel can be further increased if the reinforcement comprises at least two reinforcement elements and the reinforcement comprises at least one spacer, by means of which two of the at least two reinforcement elements are spaced apart from one another without contact, in particular when viewed in the longitudinal direction, vertical direction or width direction of the wall body, and/or that the reinforcing unit comprises at least two reinforcement elements and at least one spacer, by means of which two of the at least two reinforcement elements are spaced apart from one another without contact, in particular when viewed in the longitudinal direction, vertical direction or width direction of the wall body.
  • the panel can comprise at least one frame unit which is fixed flatly against the edge of at least one of the at least one recess in the wall body and which surrounds the recess in a frame-like manner in its entirety or at least in sections.
  • the frame unit can be made stable and lightweight if the frame unit comprises at least one plate-like frame element comprising a cement-bonded chipboard.
  • the cement-bonded particle board can comprise a board-shaped wood material formed from wooden rods or a plant material such as hemp or flax. A mineral binder such as cement is also added.
  • the plate-like frame element can have any thickness. It is advantageous if the frame element is at least 2 cm thick, in particular at least 2.2 cm thick.
  • the panel for forming the wall is provided only with the recesses in the wall body and the reinforcement.
  • embodiments of the panel comprise at least one door element and/or at least one window element that is fixed in the at least one recess.
  • the door element and/or the window element can then be mounted on the frame unit.
  • an embodiment of the panel is preferred in which at least one fire barrier element is provided, which forms an outer edge of the panel and is fixed in place against the wall body.
  • the fire barrier element and the wall body can have the same thickness.
  • the fire barrier element continues the wall body on at least one side.
  • the fire barrier element can have a thickness of at least 0.20 m, in particular of at least 0.22 m.
