AI Technical Summary

Technical Problem

Existing fastening methods for attaching wall elements to base plates in prefabricated construction, such as in prefabricated houses, are inefficient as angle brackets cannot be pre-attached due to protrusion issues during transport, complicating assembly.

Method used

A two-part fastening device comprising a tension plate and a base plate, where the tension plate is pre-attached to the wall element during manufacturing, allowing for a positive connection through a two-part movement sequence involving horizontal and vertical components, enabling secure attachment without protrusions during transport.

Benefits of technology

Facilitates easier and more stable assembly of wall elements to base plates by allowing pre-attachment of the tension plate, simplifying transport and ensuring a secure, positive connection during assembly, particularly in timber structures and prefabricated houses.
