METHOD OF MULTI-STOREY BUILDING LIGHTENED FLOORS INSTALLATION Russian patent published in 2018 - IPC E04B5/32 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction and can be used in the construction of lightened floors of multi-storey residential and public buildings, namely, when erecting buildings with load-bearing walls, and monolithic buildings in a permanent formwork. Method of constructing lightened slabs of multi-storey buildings includes the construction of load-bearing walls, monolithic reinforced concrete floors with formwork. At the same time, the overlap is made of steel reinforced concrete in a non-removable formwork, and non-removable formwork is made of universal modular elements, the height "H" of which is equal to at least 1/30 of the span of the monolithic structure of the floor. Universal modular elements are joined together and installed on load-bearing walls. Inside the universal modular elements are placed reinforcing bars and additional reinforcing frames, which are made in the form of a vertical reinforcement mesh, the upper horizontal reinforcing mesh and fill the interior of the universal modular elements with concrete. Moreover, the supporting part of the floor is filled with heavy concrete, and the span between the supporting parts of the floor is filled with lightweight concrete.

EFFECT: technical result consists in reduction of the own weight of the building and of the loads on the foundation of multi-storey buildings by lightened floors installation with an increased bearing capacity, having improved operational properties for sound insulation and thermal performance.
