With metal spreading
anchors, certain spacing distances must guaran-

Wall materials
Full brick with dense struc-

The main differences are the fastening substrates
and load classes. hollow brick
Full bricks with porous
structure, e. the edge component. the metal
spreading anchors develop lateral forces when sub-
jected loads, break-outs may occur when the pre-
scribed spacing distances are not complied with.g. lightweight
concrete, expanded clay,
pumice

ture, e.g. hollow blocks

and approved for use concrete, there are also spe-
cial solutions for various masonry types, even for hol-
low brick porous concrete.
For walls and ceilings old, existing buildings, so-
called extraction experiments are often required, or-

the construction. 20/25
