The JORDAHL® punching shear reinforcement JDA are used for the transmission of high shear forces in flat floor applications with reduced requirements for formwork and reinforcement and for optimum use of space. They can also be used for foundations and consist of double-headed anchors connected by a strip.
In comparison to slabs without punching shear reinforcement, the punching shear resistance and load-carrying capacity can be clearly increased
Reduced requirements for formwork
Installation possible from the top and bottom
Can be used for slabs from a thickness of 18 cm
Quick and simple installation
Lower construction height of the ceiling due to higher load-carrying capacity than conventional reinforcement technology
Level ceiling underface
Can be used for all support positions and support forms
Versatile fabrication possible depending on static requirements.
Double-headed anchor: made of B500B
Strip: made of structural steel
