The round foundation tubular casing type FKR or FKLR was developed in the mid-1990s at our company and introduced on the construction market with a shaft profile of 10/26 mm. With development, it was very important for us to find a solution with which we could produce any diameter.
System descriptions:
Every diameter from 120 mm is available.
By profiling 10/26 inward and outward, the result is high stability to absorb the pressure of the fresh cement
The recess is ideally suited as casing for an anchoring
system, e.g. machine foundations in which high dynamic forces generally occur. Due to the large profiling, the round FKR-model is superior to the recess and displace-ment pipes for this application.
Compared to angular recesses, the round ones only
have to be braced with considerably larger dimensions.
The system has proven to be extremely effective as
exterior casing.
The system can also be manufactured in a shaftprofiled
perforated plate construction. This creates an optimal bound between the concrete and the casing shell. The cement dispersion dimension should not exceed 40 (consistency range K2), otherwise we recommend the non-perforated, closed model.
