Separable sheath floor-adding structure of masonry buildings and floor-adding method thereof
The invention discloses a separable sheath floor-adding structure of masonry buildings and a floor-adding method thereof, and belongs to the technical field of building reconstruction. Pile foundations are arranged under steel reinforced concrete battened columns, bottom plates and wing plates are arranged on the bottoms of the columns, the steel reinforced concrete battened columns are arranged on bearing tables in a floating mode, pre-stress steel strands are arranged between the lower parts of the steel reinforced concrete battened columns and the bearing tables, and the parts, higher than the masonry buildings, of the steel reinforced concrete battened columns are connected through steel Vierendeel trusses. According to the invention, the earthquake action is weakened through the structure swaying principle; the wing plates can be bent to dissipate energy and can be conveniently replaced after earthquakes; the sheath floor-adding structure has the self-restoring ability through the pre-stress steel strands, and structural residual deformation after the earthquakes is reduced. The separable sheath floor-adding structure overcomes two earthquake resistance shortcomings namely fragile first layers and large spans of common separable sheath floor-adding structures, and has the advantages that the earthquake action can be weakened, the structural damage parts can be controlled and the structural functions can be restored. According to the floor-adding method, all construction work is carried out outside the buildings, and problems caused by indoor construction are avoided.
