FIXED FORMWORK SYSTEM FOR LARGE-BLOCK CONSTRUCTION OF BUILDINGS Russian patent published in 2020 - IPC E04B2/86 

FIELD: construction.

SUBSTANCE: invention relates to construction, and can be used in erection of residential, industrial and public buildings, as well as special structures. Non-detachable shuttering system for large-block construction of structures, comprising shutter shields assembled from universal modular elements, with torsion boxes and reinforcement frames arranged in caisson former, wherein the formwork shields are made in the form of large formwork panels, the dimensions of which are made proportionate to the width and/or height of the span as per the erection of the wall, width and/or length of the span as applied to the erection of the floor and the covering, wherein large formwork panels for erection of walls, floors and coatings are connected by ties and/or conductors and are made in form of mounting modules, wherein each universal modular element is made of galvanized or stainless steel from sheet workpiece by cold forming or rolling with cross-section in form of open trapezium, wherein in cross-section of universal module element is made in form of open trapezoid with small base-shelf and is a caisson former for arrangement of reinforcement frame and filling with concrete, and the lower larger trapezoid base of the profile is non-closed and consists of flanges with a defined structure, wherein the universal modular elements are connected to each other in mounting modules.

EFFECT: technical problem of the invention is reduction of labour costs during erection of structures, reduction of construction time due to enlarged assembly of shutter shields into large formwork panels, made in form of mounting modules, which can be used in erection of objects, to which requirements of high bearing capacity are required, including during erection of monolithic structures, which take up high loads from external influences.
