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.
Applications: Flat floors and footings
Using JORDAHL® JDA punching shear reinforcements high column forces can be transferred in flat floors and footings, with minor formwork and reinforcement effort, allowing floor heights to be optimally exploited. The double-headed anchors are connected by a perforated foundation tie, can be used in in-situ concrete and element floors, and offer numerous advantages: Punching shear resistance and load bearing capacity can be increased by up to 90%, they can be installed from above or below and installation is especially fast and simple. The JORDAHL® JDA punching shear reinforcement is available in a number of designs, and we can also design flexible solutions for you, depending on your project's individual structural requirements.
The JORDAHL® JDA punching shear reinforcement has been awarded ETA-13/0336 and national technical approval under the number Z-15.1-214.
