Abstract
The possibility of installing a floor slab made using additive technologies by layer-by-layer printing by a crane in the design position is being studied. According to the design, this plate consists of an outer and an inner layer, which are connected by an undulating inner element. The floor slab measuring 4.85 meters is planned to be manufactured on the ground in a vertical position, then the structure is transferred to a horizontal position by a crane and mounted in the design position. For this design, the finite element method is used to calculate 3 cases for the action of a crane load. The calculation results showed that when the structure is rearranged in a vertical position, the probability of tearing off the sling loops is high. When the structure is rotated from a vertical position to a horizontal position, cracks opening of more than 0.5 mm are observed in uncovered areas. When lifting the plate in a horizontal position by a crane and installing it in the design position, there is a multiple crack opening of more than 0.5 mm. Based on the calculation results, it was concluded that printing large floor slabs in a vertical position is not advisable, since during subsequent installation the structure receives multiple cracks and is not suitable for overlapping a residential building.
