Definitions

  • the brick is widely used in construction for the construction of load-bearing and non-load-bearing walls.
  • the procedure described under variant A specifies a simple execution method for erecting brick walls with central vertical prestressing.
  • the methods described under Variant B1 and Variant B2 are suitable for executing brick walls with external vertical prestressing or for executing reinforced concrete walls with vertical prestressing.
  • Variant A Central vertical prestressing for brick walls (see Fig. 1)
  • the brick wall is connected from one floor to the other by the lost pipes (4), which are integrated into the ceiling when the ceiling (7) is poured in and which also serve as stakeout for the brick wall on the upper floor.
  • the last pipe (4) lost is cut off at the desired height.
  • Variant B1 Outside vertical prestressing for brick walls (see Fig. 2)
  • Variant B2 Vertical single wire prestressing for reinforced concrete walls (see Fig. 3)
  • the device presented here consists of a fixed autonomous head which is able to automatically hook the prestressing wire inserted into it. Thanks to this device, the prestressing work can be reduced to only two phases, inserting the individual wires and prestressing them, both from the same starting position (i.e. from above).
  • the two openings (10) make it possible to inject the empty space in the funnel of the device and in the lost pipes. Opening (12) allows the vent tube to be attached to check the injection from below.
