Definitions

  • scarf body for the production of recesses and openings in cast concrete components, which can be fastened by means of tabs to a ceiling or wall formwork, characterized in that the scarf body consists of a prefabricated blank (A) made of wet-strength corrugated cardboard with a smooth surface, the is folded into a cuboid hollow body (1) with four side walls and a floor wall (8) facing the ceiling or wall formwork, and that a handle device is formed in the hollow body (1), which is accessible from the ceiling side opposite the floor wall (8) is.
  • A prefabricated blank
  • A wet-strength corrugated cardboard with a smooth surface
  • Scarf body according to claim 1 characterized in that the top side is covered by a closure flap (4) which extends from the edge (e) of a side wall (3) of the hollow body (1).
  • scarf body characterized in that it is formed in one piece, that the blank (4) forming the side walls of the hollow body, each via a fold line (a, b, c) side by side interconnected rectangular panels (9 , 10, 11, 12), on the contacting side edges of which there are plug-in tabs (13, 14) and cooperating cut-outs (15, 16) which provide a plug-in connection, and that the handle device is formed by a section (B), which is folded in around the edge (d) of a panel (10) and in turn is folded into a right-angled, four-sided body, a recess (17) being formed on a bottom portion of a surface, which forms a handle opening.
  • scarf body according to claim 1 or 2 characterized in that the four-surface body is held in position by means of a plug connection (18, 19).
  • the handle device is formed by a portion which is folded inwards around the edge of a panel and in turn is folded into a rectangular, four-sided body, a recess being formed in a bottom portion of a surface which forms a handle opening.
  • the four-surface body is preferably held in position by means of a plug connection.
  • the formwork body is secured from being pressed in by the grip device attached in the form of a ring brace.
  • the scarf body can be pulled out after use by pulling on the handle device.
  • a blank B which initially comprises four rectangular panels 9, 10, 11 and 12 forming the side walls of the scarf body, which are arranged side by side and can be folded and plugged together along the fold lines a, b, c.
  • a tongue 13 and a recess 16 are formed on one side edge of the panel 9.
  • a recess 15 is provided for the passage of the plug-in tab 13, wherein a plug-in tab 14 can be guided through the recess 16 in order to create an unintentionally non-detachable plug connection.
  • a tab 4 is formed, which has a plug edge 5.
  • the plug-in tab 4 closes the upper surface or the top side of the hollow body and the plug-in edge 5 rests against the inner surface of the rear side wall of the hollow body.
  • a section B (FIG. 1) can be folded around an edge d, which in turn is designed such that the bottom of the hollow body is formed by a bottom wall 8 and is thus closed, while the sections adjacent to the bottom wall 8 are each 90 0 are foldable against each other and then form a four-dimensional body, which is held in position by the plug-in connection in the form of a plug-in tab 18 and an opening 19, the two surfaces of section B adjacent to the bottom wall 8 on the inner surface of the respective one side wall of the hollow body forming panels 9, 11 abut.
  • a recess 17 forms a handle opening and is accessible from the ceiling side of the hollow body when the flap 4 is folded up.
  • the formwork body can be nailed to the wall or ceiling formwork by means of tabs 6, 7a, 7b (see FIG. 1), so that the desired cavity is formed when pouring concrete, care being taken that no concrete can flow into the formwork body itself .
  • the formwork body described consists of corrugated cardboard of high-quality material composition with wax-coated inner and outer surfaces and can be used in particular in the manufacture of recesses in concrete ceilings of different thicknesses.
  • the blank shown in FIG. 1 can be produced by simple punching, the corresponding fold lines also being prepared by technically not complex measures, so that the formwork body can be plugged together at the construction site into the hollow body shown in FIG. 2 with a few hand movements.
