What solutions are available?
As a solution, Halfen company provides two different versions for a subsequent connection. One option is the Halfen HBT Rebend Connection type 7.
The closed casing is nailed onto the formwork and after dismantling the formwork of the first casting step the stirrups are bended out of the case. Afterwards the bracket is concreted.
Another version is to realize the bracket in a second concreting process, which is provided by the screw connection Halfen HSC Stud Connection (Fig. 1). Owing to sleeve and threaded rods it is possible to place concrete in two steps.
