Abstract: The present invention relates to a formwork construction method for inner wall and device thereof. The construction method includes stripping, hoisting, supporting and spreading the formwork, in which, hoisting of the formwork is achieved with crane. Stripping and spreading of the formwork is achieved by a transverse motion machine making the driver rotary spreading and the driven liner spreading. The driver of machine leans against the wall, and the driven connect with the formwork. The formwork is supported on the bearing block of the inner wall by a bracket hinged under the formwork. The transverse motion machine makes use of a screw drive mechanism, which can enhance the bearing abilities and have a function of self-lock.

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.
