In the place of relatively small blocks of walls and tunnels of the basement weighing 0.15-2.92 tons in housing construction since 1964 for strip foundations, foundation enlarged panels of a flat or taurus weighing 4.1-5 tons are used.
The PF-1 foundation panel, which has a continuous wall, is mounted under the longitudinal outer wall, and such panels as PSP-1 and PF-2 with holes made in the vertical wall-for the longitudinal internal wall of the structure. PF-2 panels are also used for foundations for internal transverse walls.
Columns
In industrial buildings, the most commonly used columns of the two -voltage and rectangular cross -section with and without consoles, strapping and crane beams are laid on them.
