METAL FRAME OF MONOLITHIC REINFORCED CONCRETE SLAB Russian patent published in 2017 - IPC E04C2/06 

FIELD: building.

SUBSTANCE: invention relates to the field of monolithic construction and can be used for the construction of large buildings and structures, including the construction in seismic regions. The known frames consist mainly of rebars connected or welded together at a construction site. They have low resistance and stability and are very laborious. The essence of the invention consists in that the metal frame of a monolithic reinforced concrete slab is made of thin-walled profiled rolling in industrial plants as closed welded panels with gaps between adjacent panels. At the construction site only assembly is carried out without welding with bolt- fastening. On its bottom sides mounting holes are made for formwork installation. On the side faces of the frame mounting holes are made with the help of which high-strength bolts and tightening screws execute the connection of separate panels to each other for achieving the state of prestressed slab construction. The panels can be made of welded together angle bars, rectangular tubes, channels, I-beams.

EFFECT: invention increases the carrying capacity of the metal frame and, consequently, slabs, reduces the construction time and cost, enhances its manufacturability.
