Moving bearing between upper and lower structures - involves connection to plinth inserted in substructure cavity, and mortar filling

摘要

Less time is involved, and more complete control made feasible, in a process for shifting a bearing (1) between a superstructure (2) and a substructure (3). It is connected to a solid plinth, which is then inserted in a depression (6,7) provided in the substructure. The dimensions and arrangement of the plinth and depression are such that the bottom edge and top edge of the plinth are respectively below and above the substructures top edge. An interval retained between plinth and depression is filled with a cast substance such as mortar (8). The plinth, connected to the bearing, may first, be inserted in the depression, the interval being subsequently filled.
