FIELD: construction.
SUBSTANCE: invention relates to construction, particularly, to connection of steel columns with foundation. For rigid connection of steel two-branches columns with foundations there used are toothed anchor racks and fastening fixing rods. Anchor strips have regular pitch of sine teeth. Width of pairs of anchor and fastening racks is equal and less than width of double-tee profiles of columns by one third. Pair of fixing racks are turned by teeth outwards. They are welded fixed to shelves of column branches. Ridge sides are tightly adjoined to shelves outer surface. On the contrary, the pair of anchor racks is facing the teeth of the fixing rods with their teeth. Teeth are tightly aligned, and contact is made thus excluding shifts.
EFFECT: reduced labor intensiveness of installation.
