Void Forming Tubes

Economical and easy application
Displacement pipes allow for  the  safe, quick and economical construction of hollow bodies in hollow plate bridges and ceilings. The  dimensional accuracy, tightness and high resistance to deformation of these industrial cavity elements guarantee the  implementation of the  calculated static values in the  structure.

Easy and flexible
Despite their low weight, the  displacement pipes can be installed in the  concrete without stiffening. Additionally, the  corrugated profile provides a certain flexibility, which allows for  the  laying of displacement pipes also in a bent course. Despite these characteristics, the  resistance of the  pipe to longitudinal deformation is so high that the  distances between the  lift prevention locks can principally be adapted to the  stability of the  applied supports.If the  displacement pipes are to be secured against lift, it is recommendable to apply the  specifically developed Hydra single and double anchoring elements. They are tested for their static properties and guarantee utmost avoidance of showings, above all of rust stains at the bottom of the ceiling.

The  different assembling and disassembling methods of the  supports allow for  compliance with  the  individual requirements in the  individual structures. it  is possible to install and to remove the  lift prevention locks exclusively from above, if this should be very difficult or impossible from below, due to the  specific conditions.

Your Advantage:

  • greatest available dia. 1,500
  • Delivered in every transportable length
  • Additional shearing connection with the concrete by means of their corrugated profile
  • The implemented reduction of the Tube end avoid undesired notch tensions

Use in Ceiling Areas
The use of displacement pipes made by wbr makes modern concrete building more economical and faster – either with site-mixed concrete or with ready-mixed concrete, or with a combination of both variants. The great number of applications of our products and the great variety of versions allow for new approaches, even with solutions which go beyond conventional procedures.

Application in Core Slabs (Building Shell Pipes)
Hydra displacement pipes (hollow elements) can also be used in the construction of commercial or industrial buildings because of their harmonized dimension ranges when it comes to constructing modern and slender buildings

Application in Bridge Construction
The application of pipes made by wbr as hollow parts in bridges allow for savings in reinforcement steel and concrete. This will result in a considerable weight reduction. The „more slender“ buildings made in this way will integrate themselves better into the landscape and thus require less interference. In this way, Hydra displacement pipes allow for economical building not only in the foundation of a bridge but also in the structure itself.
