Definitions

  • the invention relates to a device and a method for the spaced connection of a first and a second flat concrete element, preferably carbon concrete walls, with a thickness between 1 and 5 cm, preferably between 2 and 4, particularly preferably 3 cm, to an element wall comprising the concrete elements a textile reinforcement, the device being designed as a shaft anchor, the shaft anchor comprising a shaft with a first and a second end, the shaft anchor having a length that defines the intended spacing of the concrete elements in the element wall, the first end serving as an anchor foot is trained.
  • Element walls which have been known for a long time from the prior art, also referred to as double walls, triple walls, triple-chamber walls or hollow walls, are, according to the usual practice, storey-high semi-finished parts made of two 4.5 cm to 7.5 cm thick reinforced concrete shells which are connected to one another by a lattice girder .
  • the reinforcement is installed in the factory when the element walls are manufactured.
  • the space in between is poured on site with in-situ concrete so that the overall cross-section is monolithic.
  • the element wall thus represents lost formwork.
  • the element wall can be produced in exposed concrete quality on both sides. Since the surfaces are generally very smooth, plastering can generally be dispensed with.
  • non-exposed concrete walls only the joints of the element joints and, if necessary, the pores of the air inclusions are filled and the surfaces z.
  • B. painted or papered. The construction enables a very economical construction.
  • connecting elements are used to connect the individual walls parallel and spaced apart.
  • the usual procedure is to concrete a facing including steel reinforcement and then to place thermal insulation on it.
  • the connecting means are then pressed into the still fresh concrete through prefabricated holes in the thermal insulation.
  • the arrangement is turned and the free ends of the connecting means are immersed in the freshly concreted supporting shell, in which there is already a steel reinforcement.
  • Such solutions are from the publications EP 2500479 A1 , DE 19516134 A1 , EP 0825310 A2 and DE 20008530 U1 known.
  • the publications disclose further manufacturing processes for the erection of double-shell walls US 1762099 A , DE 19951913 A1 , CH 161758 A . It is also possible to glue the connecting means to the hardened wall shells, like the publication EP 179046 A2 can be seen.
  • a connecting element designed as a sleeve anchor for concrete parts is from the document EP 0 698 702 A1 known.
  • a sleeve anchor for concrete parts is disclosed, consisting of an internally threaded stop sleeve and an anchor shaft with an integrally formed flat anchor foot, the anchor shaft protruding with its connecting end facing away from the anchor foot into a connecting section of the stop sleeve, which is pressed with the connecting end.
  • plate foot is unsuitable for textile reinforcement, since it either does not pass through the mesh openings in a mesh-like textile layer, e.g. B. can be performed in a scrim or find insufficient support behind the reinforcement.
  • the publication DE 10 2012 025 629 A1 relates to spacers 44 for insertion into components to be produced with a base material with integrated textile reinforcement, which contains at least one textile reinforcement layer 21, which consists of at least two crossing yarns, comprising at least one locking holder 3 and a counter holder 24 adapted and positioned on the locking holder 3.
  • the locking holder 3 having a shaft 9 has unevenness, overhangs and / or projections 11, 12 on the shaft 9 which, in the case of locking, produce a non-positive connection with a hole 6 in the selected and adapted counter-holder 24.
  • the locking holder 3 has a hat-like, circular head 7 which is attached to the shaft 9.
  • the shaft 9 of the locking holder 3 has a full cross section for the arrangement between the textile yarns or a free cut which corresponds at least to the textile yarn thickness in order to enable an arrangement above the textile yarn.
  • a defined distance between the textile reinforcement layer 21 and the formwork boundary or outer component surface is thus formed between the textile reinforcement and the formwork boundary or the outer surface of the component by means of the spacers 44.
  • the publication GB 2 399 108 A describes a wall anchor for a textile reinforcement that can be attached spaced from a structure.
  • a wall fastening anchor for use with a wall fastening element for anchoring a second structure, for example a textile reinforcement, to a first structure, for example a wall.
  • the anchor may have pairs of rotationally offset projections, preferably extending radially from the end of the tubular anchor, and spacing the textile reinforcement from the wall.
  • the manufacture of the projections is complex. The same applies to assembly, in which the different projections have to be placed between the yarns of the textile reinforcement.
  • a spacer for a reinforcement layer, a reinforcement arrangement for a concrete component and a method for producing a reinforcement arrangement according to the document are also from the prior art DE 10 2013 015 434 A1 .
  • the spacers are installed by inserting them into a mesh of the reinforcement layer and connecting them to it by rotation.
  • the spacer has at least one fastening arrangement which acts essentially in a first plane, which is spanned by the circumferential direction and the radial direction of the spacer and which is connected to the spacer body.
  • the fastening arrangement has at least two connecting elements for the strands or bars of the first reinforcement layer.
  • the connecting elements each have at least one groove which has a first and a second groove wall, the longitudinal axis of which lies in the circumferential direction of the spacer and the opening of which points outward in the radial direction.
