Technology of repairing brick masonry cladding of multi-layer external walls using helical repair anchors

摘要

As a result of mass construction of residential multi-storey buildings with non-bearing multi-layer walls and brick masonry cladding, during recent 10 years a number of drawbacks were found in design solutions leading to structural failure already at the initial stage of operation. Relevance of this problem is caused by poor reparability of multi-layer wall structures without removing the external brick cladding. The paper describes engineering solutions developed including authors’ efforts for repairing such walls without removing the cladding layers.
