METHOD FOR RECONSTRUCTION OF BUILDING Russian patent published in 1997 - IPC

FIELD: construction engineering. SUBSTANCE: this relates to building-on of houses and low-storey public buildings with roofing made of reinforced concrete slabs placed over inclined beams. According to method, inclined beams and slabs placed over them are released from their fasteners over perimeter of technological mounting. Then joints between them are cleared out. Then, ends of beams together with slabs over their entire technological mounting are raised to horizontal position. Raising is effected in stages at pitch equal to 1/20-1/50 of total lifting height with fixing at each intermediate position. After that, walls are erected of top auxiliary story and beams are lowered down on newly built walls. EFFECT: high efficiency. 1 dwg
