On behalf of Kappa Filter Systems GmbH, the Deutsche Technologiedienst is looking for industrial partners interested in a:
“New type of a screw connection system for precast concrete elements able to transmit tensile, transverse and shear loads“.
Currently, simpler devices such as anchor and expansion head screws, welded joints or complex special solutions are used to connect concrete elements. For this type of connection, however, it is necessary to absorb forces in X, Y and Z directions. Existing screw connections do not have sufficient pull-out strength. Kappa Filter Systems GmbH has now developed a screw connection which, for the first time, allows XYZ forces to be transmitted to concrete slabs by means of a detachable connection.
Some advantages of the system
- Exact construction of concrete walls composed of several concrete slabs
- Highly stable connection with absorption and diversion of high tensile, compressive and transverse forces
- Quick assembly with simple screwing tools: no welding equipment or means of transport for flowing or ready-mixed concrete (especially for wall heights above 3m) necessary, reduced crane operating times
