As soon as the filling / pre-compression is complete, i.e. before the main compaction with a press stamp, this can Fasteners removed from the mold area of the mold because then the reinforcement cage is already surrounded by the surrounding one pre-compacted concrete is held.
  • the fasteners can be formed by rods, which by appropriate Holes in the press wall are pushed into the mold area. The reinforcement cage then lies on these bars. Instead of Rods can also use other fasteners such as pins, clips, Hooks etc. can be used. Preferably, several preferably two fasteners in the longitudinal direction of the Press mold provided spaced so that the reinforcement cage in Can be positioned exactly in both the transverse and longitudinal directions. Axial extensions are particularly suitable as fastening means Elements such as pens, rods, rods with any, in particular circular profile since these elements after pre-compression relatively easy in the axial direction from the Die can be pulled out without being pre-compressed Concrete gets stuck or through radially protruding parts damage the surrounding pre-compacted concrete.

  • the diameter of the bore is preferably the diameter of the Fasteners adjusted so that the diameter the holes are at least 2% and at most 25% larger than the diameter of the fastener. This will, on the one hand secure positioning of the fastener without much Game guaranteed, on the other hand, a smooth insertion and pulling the fastener into and out of Drilling possible. Any canting of the fastener can by moving the fastener around the longitudinal axis be solved around what the use of circular and / or wedge-shaped profiles favored.
  • the recesses in the press mold to hold fasteners can also be designed as slots in the mold wall his.
  • the slots then preferably extend to the top Edge of the mold. At least the width of the slots is preferred 2% and at most 25% larger than the diameter of the fastener.
  • too relative size of recess and fasteners on the one hand secure positioning of the fastener without much Game guaranteed, on the other hand a smooth insertion and pulling the fastener into and out of Slot allows. Any canting of the fastener can by moving the fastener around the longitudinal axis be solved around. Due to the expansion of the slot in This movement can be compared in the direction of the edge of the mold to the above-described bore even reinforced become.
