Definitions

  • the invention relates to a wall construction element with a concrete inner shell, an insulating layer arranged at a distance from and parallel to the inner shell, and an outer shell lying against the insulating layer.
  • Insulated wall elements of this type are known from use.
  • the connection of the inner and outer shell of these known wall construction elements is used to connect lattice girders or bolts, in particular bolts made of glass fiber reinforced plastic, which are partially embedded in the shells and penetrate the insulating layer.
  • the present invention creates a new wall element of the type mentioned at the outset, which is characterized in that the outer shell is connected to the insulation layer as a facing shell via pieces of tissue or film partially embedded in the facing shell.
  • the insulating layer has a supporting function in this wall element.
  • the outer shell which is designed as a facing shell and connected to the insulating layer via flexible pieces of material, does not itself take on any or only low loads.
  • the facing shell is preferably a cast concrete shell or a layer of plaster, possibly 10 cm thick, applied to the insulation layer.
  • a fabric layer parallel to the wall plane, in particular a textile fabric layer, is preferably embedded in the facing shell as reinforcement.
  • mineral foam for example, can also be used as material for the facing.
  • a reinforcement layer preferably in the form of a fabric layer, can also be incorporated into the insulation layer, preferably as a plaster layer when producing the facing layer.
  • At least two pieces of fabric or film are preferably provided at least in an upper region of the facing shell.
  • the pieces of fabric or film preferably protrude into slots in the insulation layer at an incline to the wall plane.
  • the inclination generates both vertical and horizontal holding forces, which press the facing layer against the insulation layer.
  • the fabric or film pieces can each be clamped in the insulating layer by means of a wedge-shaped insert which forms a component of the insulating layer.
  • projections protruding from the insulating layer also engage in the facing, with which the facing can also be connected.
  • projections can be formed by elements connecting the concrete inner shell to the insulating layer, in particular extensions of connecting bolts.
  • the connecting elements have a widening that engages behind the insulation layer for transferring the pressure from in-situ concrete that can be filled between the inner shell and the insulation layer.
  • the widenings of these connecting elements preferably connecting bolts, preferably made of fiberglass-reinforced plastic, are expediently designed in the form of plates.
  • a prefabricated, preferably storey-high wall element 15 with a horizontal length of e.g. 4 m has a concrete inner shell 1, an insulating layer 2 arranged at a distance from the plate-shaped concrete inner shell, and an outer shell 3 as a facing layer resting against the insulating layer.
  • the thickness of the inner shell 1 is 4.5 cm
  • the insulation layer 2 is 10 cm
  • the thickness of the outer shell 3 is 2 cm.
  • the distance between the concrete inner shell 1 and the insulation layer 2 is 7 cm. Core concrete can be poured into the space 4 formed on site.
  • connection between the plate parts 1 to 3 of the component are used in a grid arranged bolts, of which in the partial illustration of Fig. 1 a bolt 5 is visible.
  • the bolts 5 consist of a glass fiber reinforced plastic, in particular glass fiber reinforced polyamide.
  • one end at 6 of the bolts 5 is embedded in the concrete of the inner shell 1 and engages behind the insulation layer 2 with a plate-shaped expansion 7.
  • An end section 8 of the bolts 5 protruding beyond the plate-shaped expansion 7 protrudes into the outer shell 3 inside.
  • such bolts 5 are provided per square meter.
  • a fabric layer 9 parallel to the plane of the plate is embedded as reinforcement, which in the example shown is formed by textile fabric.
  • the fabric layer 9 could e.g. also a plaster base or screed mat made of stainless steel.
  • Fig. 2 pieces of tissue 10 with an end section are embedded in the outer shell 3, the pieces of tissue forming a connecting strap for connecting the outer shell 3 to the insulation 2.
  • tissue pieces 10 each protrude according to Fig. 1 into a slot 11 traversing the insulation layer 2 and preferably with an end section 12 beyond the slot 11 into the gap 4 that can be filled with core concrete can be pushed into the insulating layer 2 in the direction of an arrow 14 with the tissue piece 10 jammed with the insulating layer 2. It goes without saying that the compressive strength of the insert 13 can differ from the compressive strength of the rest of the insulation layer 2.
  • the insulation layer 2 is a load-bearing insulation layer which gives the component at least sufficient strength for transport to the construction site and is also able to hold the facing shell 3 together with the bolts 5.
  • the facing shell 3 is connected on the one hand to the end sections 8 of the bolts 5 embedded therein, while on the other hand both a vertical load is absorbed via the fabric pieces 10 and a compressive force that pulls the facing layer 3 onto the insulation layer 2 is generated perpendicular to the plane of the panel becomes.
  • the end section 8 can advantageously absorb wind suction forces and prevent the facing shell from breaking open in the event of greater temperature gradients. It expediently has a profile. Furthermore, the end section 8 can absorb adhesive forces that occur when the hardened facing concrete is lifted from a form of form. Furthermore, the end section 8 can absorb adhesive forces that occur when the facing shell is lifted off the shell mold.
  • the clamped tissue pieces 10 are also fixed by the embedded end section 12 in the solidified core concrete.
  • the plate-shaped widenings 7 engaging behind the insulation layer 2 advantageously counteract the concrete pressure of the core concrete.
  • the insulating layer 2 is first prefabricated with the bolts 5 inserted in the passages in the insulating layer and, in a next production step, placed on the still liquid concrete of the poured facing shell 3 after the fabric layer 9 and partially the fabric pieces 10 in the Concrete of the facing shell 3 have been embedded. In a further step, the fabric pieces 10 are then clamped in the insulating layer 2 by insert pieces 13.
  • the insulation layer and facing shell are inserted with the ends of the bolts 5 first into the still liquid concrete of the poured inner shell 1.
  • the facing shell 3 can be profiled for better adhesion to the insulating layer 2. If the adhesion is good, end sections 8 of the bolts 5 protruding into the facing shell 3 can then be dispensed with.
  • the insert pieces 13 could be omitted and only slots 11 receiving the tissue pieces 10 could be formed in the insulating layer 2.
  • the fabric pieces 10 can consist of the same material as the fabric layer 9 forming a reinforcement or can be made of a material different therefrom. It goes without saying that pieces of tissue or film only mean pieces of material that are extensive in the form of tissue or film, for example textile-like reinforcement grids or angled, less flexible screed grids made of stainless steel rods.
  • the grid can also consist of two parallel and spaced apart individual bars, which are connected by short crossing cross bars to form a narrow grid.
  • the piece of fabric 10 could extend into the inner shell 1, in which case the insert 13 would also extend as far as the inner shell 1.
  • the wall element could be hung over such a piece of fabric, e.g. on a crane hook.
