Method for raising a building

摘要

A method for raising a building (1) provided with a number of load-bearing elements (4); a horizontal cut is made through each load-bearing element (4) along a cutting line to define a lower portion and an upper portion of the load bearing element (4) reciprocally separated by the cutting line; making a series of niches (11) immediately underneath the cutting line and through the load-bearing elements (4); at least one thrust device (12) is arranged at each niche; each thrust device is operated so as to apply an upward thrust between the lower portion and the upper portion of the load-bearing element (4) and determine the progressive raising of the upper portion of the load-bearing element (4); at the end of the raising operation, a series of supporting piles (19) is arranged between the lower portion and the upper portion of load-bearing elements (4); and finally the thrust devices (12) are removed.
