FIELD: construction.
SUBSTANCE: invention relates to interfloor lightweight flooring of a building. Lightweight flooring comprises formwork, reinforcement carcasses with working reinforcement and reinforcement mesh. Formwork is fixed with possibility of formation of cavities and caissons for filling with concrete mixture. Each reinforcing frame is placed in each caisson, and the fixed formwork is lined from below, at least in one layer, with a sheet fire-retardant material, which is attached to caissons of fixed formwork by means of metal fasteners, wherein concrete mixture is laid in fixed formwork in form of two layers: in form of lower layer of heavy concrete and upper layer of light concrete.
EFFECT: building higher bearing capacity.
