Definitions

  • the invention relates to a molded part, which consists of a malleable building material especially as lost formwork is produced and the use of a malleable building material and a method for producing a molded part by extruding a building material and a device for the production of a molded part from a extrudable building material.
  • molded parts are called Molded parts, in particular for the production of precast concrete parts used on site either immediately can be used, or still with building materials how concrete has to be filled and one yourself Formwork formwork.
  • Fig. 1 is a concrete strand for producing a molded part with parallel to the longitudinal direction (extrusion direction) lying reinforcements 2, 3 shown.
  • the reinforcement 2,3 consists of a rigid steel wire with a diameter of 6 mm.
  • materials other than Longitudinal reinforcement suitable.
  • the molded part is created after the curing or setting of the Concrete string and is used in particular as a formwork element used for lost formwork.
  • the 4a is a device for producing a concrete strand 40 outlined.
  • the device has one Extruder 41, which extrudable building material in one Press head 42 presses into it. At the other end is the Press head closed with a mouthpiece 43, in which an outlet opening 44 is provided from which the concrete strand 40 finally exits.
  • the press head In the press head it will round profile of the extruder for the production of the Concrete strand cross section required changed in present case on a rectangular cross section, so that in the horizontal section the press head 42 is flared is.
  • feeds 45 provided, via which reinforcing threads 46, 47 fed are then embedded in the concrete strand 40 are.
  • Fig. 7a is the extruded, not yet hardened Concrete strand 70 shown, the parting line 71st has, so that individual pieces 72 arise. About that it can also be seen that in the area of the separating cut there is no reinforcement, the reinforcement is heard in FIG. 7a just before the cut and starts just short then on again. This allows separation with conventional Machines take place, special measures for severing the reinforcement need not be provided. This is important when the reinforcement is made Beam wire exists.
