Door sill reinforcement
Openings in partition walls made from gypsum blocks can be produced securely and without further measures as described. Through the installation of a door sill reinforcement made from flat steel, in particularly critical conditions, for example with large ceiling span widths or anticipated large structural movements, security against cracks can be increased.
Through this measure the tension zone of the wall is transferred from the area of the door supports to the foot of the wall. The nominal tensile stress is taken over by the door sill reinforcement.
