Tubular Formwork

Deliberate
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 with Corrugated Profile

 

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 with a profile depth of approx. 2 cm.

Sheeting Cases according to DIN standard 1045-1

Improvement of bonding quality and high precision in the
definition of shearing force transfer – these are the pros of the new DIN standard tubular elements made by wbr. This provides safety in planning and installation, since the interlocked joint allows for the use of the full roughness parameter in calculation.

Shuttering Cases with Corrugated Profile -perforated-

Static specifications may require the application of perforated sheeting cases. In addition to an optimum connection (concrete grout is able to intrude through the perforation which causes an interlocked connection with the concrete of the foundation, which avoids the potential separation of the sheeting case before the grouting process) an increase in shearing strength is implemented.
