Tubular Formwork

The flexibility and variety of the products from the wbr GmbH becomes clear also with the tubular formwork. The customer can basically select from four different types, which all will individually meet the required features.

Besides the classical corrugated profile made of metal sheets, which is used as foundation quiver or for other recesses, this profile type is also used as perforated sheet metal for machine anchoring for adapting the fixtures. Thus an additional joint will be created by the perforated structure of the material besides the force-closed connection due to the corrugated profile, creating a homogenous connection between external and internal concrete. Thus a potential gap development can be avoided.

An economic solution
If strength and profile depth are wanted, then types with trapezoid profile should be used. For larger recess dimensions there is moreover the possibility to deliver trapezoid quivers as so called folding quivers to the construction site. This is one of the most economic solutions when it comes to space savings and to freight costs savings

Your Advantage:

  • Sheathing for  statically perfect foundations
  • Removal of sheathings not required
  • Uniform sheathing system
  • constant quality
  • Reduction of the  sheathing costs
  • reliable availability of the  sheeting cases within short periods
  • Better transparency of costs, lower working effort
  • Exact compliance with
    the  specified sheathing dimensions
  • flexible time planning, increase in rationalization

Sheeting Cases
The  so-called block foundation with  inserted sheeting allows for  a reduction of the  depths of excavation pits, and also for  the  avoidance of sheeting cases which require expensive sheathing and reinforcement. The  insertion of the  support into the  foundation block provides sufficient interlocking in order to introduce the  normal force into the  foundation not by pressure on the tip but by friction of the  casing.

Depending on the  customers’ requests and on the  static requirements, Hydra sheeting cases are  available in two profile versions; one with  a corrugated profile with  a profile depth of approx. 1 cm, and one with  trapeze profile according to DIN 1045-1.

Effects in Application

  • Optimum distribution of the load onto the sheeting wall
  • Compliance with  the  minimum profile depth specifications for  bucket sheathings.
  • No rotting, so they can remain in the  concrete
  • Applicable with  almost every sheathing dimensions
  • Economical manufacturing
  • Short delivery periods
  • Ready for  installation 
  • Narrow dimensional tolerances
  • Reliable connection
