<p>The prestressed building structure comprises an assembly of precast elements separated by gaps occupied by an interface product, one or more prestressing sheaths having sections respectively incorporated into the precast elements, and a prestressing tendon tensioned inside the sheath. The sheath sections are respectively fitted with first and second end pieces opening out on the facing surfaces of the two precast elements. The first end piece has a flared opening. An elastic connecting sleeve is connected in a sealed manner to the second end piece. The sleeve presses against the first end piece, which compresses it longitudinally to ensure a seal between the inside of the sheath sections and the gap separating the adjacent surfaces of the two elements.</p> |
