REINFORCED FORMWORK BLOCK WITH RETAINED FORMWORK AND BUILDING STRUCTURE Russian patent published in 2017 - IPC E04G11/06 E04G11/36 E04B2/86 

FIELD: construction.

SUBSTANCE: reinforced formwork unit with a retained formwork comprising a reinforcing cage consisting of working and structural rods connected at connection joints and at least one sheet of retained formwork attached to the reinforcing cage; according to the claimed solution, as a retained formwork sheet, a steel-fibre-concrete sheet is used, fixed at a distance of less than two diameters of the working rods from the reinforcing cage, the coaxially located working rods at their connection points are installed end to end or with a gap of not more than one diameter of the working rods, loop interblock joints are made at the ends of the working rods facing at least one side of the reinforced formwork block, and the inner surface of the steel-fibre-concrete sheet is made with an adhesive layer. Said technical result regarding the building structure is achieved by the fact that the building structure comprising a concrete-filled reinforced formwork block with a retained formwork comprising a reinforcing cage consisting of working and structural rods connected at connection joints and at least one retained formwork sheet attached to the reinforcing cage; according to the claimed solution, as a retained formwork sheet, a steel-fibre-concrete sheet is used, the inner surface of which is adhesively bonded to the concrete surface to be mated. The steel-fibre-concrete sheet is fixed at a distance of less than two diameters of working rods from the reinforcing cage, loop interblock joints are made at the ends of the working rods facing at least one side of the reinforcement formwork block, and coaxially located working rods at their connection points are installed end to end or with a gap of not more than one diameter of the working rods.

EFFECT: reducing the weight of the reinforced formwork block and the resulting building structure while simultaneously increasing their strength and spatial rigidity during transportation and installation, simplifying and increasing the accuracy of their installation.
