Abstract (en)

[origin: EP2251503A2] The presented solution concerns the replacement of a loadbearing wall (1) on infirm soil. For this a recess (2) is created on both sides of the loadbearing wall (1), piles (3) are driven at the bottom and the recess is supported with a temporary supporting wall (6). On-pile foundation (8) is built on top of the piles (3). Cross-beams (12) are installed under the loadbearing columns (11) supporting the loadbearing wall (1), and the recess (2) is backfilled and compacted. Temporary supports (18) are installed on both sides of the loadbearing wall (1) on all floors, and openings are cut into the loadbearing wall (1) for loadbearing columns (11), ad the loadbearing columns (11) are installed to cross-beams (12). Then a hole is cut for the loadbearing beams (23) into the loadbearing wall (1) for a half of its thickness under the ceiling structure (17), and first one loadbearing beam (23) and then the second loadbearing beam (23) is mounted to the loadbearing columns (11), the space between the loadbearing beams (23) is filled with a fire-retardant and sound insulating material (26) and then the section (27) of the loadbearing wall under the loadbearing beams (23) is demolished. Then the previous installation of loadbearing columns and the loadbearing beam is repeated in all the spaces between the columns until the whole column-beam system is complete.
