<p>A secondary development residential building comprises an old part including a multi-story building with walls, bridging, residential/auxiliary premises, an added part including added foundation, support elements, additional areas, staircase-elevators units, an overbuilt part of several floors. The added foundation is performed as two rows of piles, disposed along the old part's perimeter at a predetermined distance from the walls and at a distance of one span between the rows. The support elements each performed as linked columns, erected on the piles. The edged column is as tall as the redeveloped building, the other column is as tall as the old part. Common's, overbuilt floors', and added bridgings are mounted with horizontal strap and inter-floor shift stiffeners, on the columns, composing an independent framework, without transferring loads to the old part, the overbuilt part bridgings rest on the edged columns. The bridgings are mounted on the columns providing spatial rigidity.</p> |
