UNDERPINNING WITH CANTILEVERED BRACKETS
A steel cantilevered bracket can be used to hold up an existing structure on piles as illustrated above. After the piles have been driven, the cantilevered bracket is attached to the structure with steel anchors or is placed below the structure. A jack can be placed between the pile and the cantilevered bracket to exert a preload or to jack up the structure. The cantilevered bracket is concreted after the jack has been removed.
Cantilevered brackets are used in light reinforced concrete structures, for example garages, sheds, an extension to a house or strengthening of an existing foundation.
This construction with cantilevered brackets is used for load bearing capacities in the order of magnitude of 30 to 200 kN.
