Erection unit for a building floor slab and the erection method thereof

Abstract

An erection unit for a building floor slab is disclosed, which includes a load-bearing member for lifting the floor slab. Said load-bearing member is higher than a plane where the floor slab lies and fixed in a wall and connected with the floor slab by the aid of a traction member. A method for erecting the floor slab with said erection unit is disclosed, which includes the following processes: installing the floor slab mould; connecting the upper end of the traction member to the load-bearing member above the floor slab; placing the lower end of the traction member on the height where the floor slab is located; then pouring concrete; dismantling the mould and installing the next lower layer after the floor slab has hardened; taking off the traction member after the floor has solidified to a strength enough to support its deadweight.
