RETAINED FORMWORK PACKAGE, METHOD OF ITS ASSEMBLY AND METHOD OF CONSTRUCTION OF MONOLITHIC WALLS OF BUILDING AND STRUCTURE IN RETAINED FORMWORK OF MODULAR ELEMENTS Russian patent published in 2015 - IPC E04B2/84 

FIELD: construction.

SUBSTANCE: invention relates to industrial and civil engineering, namely, to methods of construction of monolithic walls of buildings and structures in a retained formwork. The retained formwork package for construction of walls of buildings, structures, comprises the external and internal formwork panels and the package elements forming the space for filling with concrete mix, and package elements are made from steel formed sections detachably connected among themselves and forming a rigid spatial structure as a modular element fitted with stiffeners and spacers, and the formwork panels are attached to each lateral surface of the spatial structure. The steel formed section is made with C-shaped cross-section of sheet steel with holes on the front plane of the section, and in the stiffeners the holes are made in lateral surfaces, and hole on the front plane of the section and in lateral surfaces of stiffeners are intended for passing of concrete mix, and/or laying of utilities, and/or installation of additional fittings for reinforcing of the structure of erected wall, and the spacers are installed on vertical racks of modular elements of the spatial structure, and stiffeners are fixed on these vertical racks through spacers made of heat and sound insulating material, the modular elements are fabricated with the height equal to the height of aperture of inter-plate flooring. The method of assembly of the spatial structure in the form of modular element of retained formwork and the method of construction of monolithic walls of buildings are also described.

EFFECT: improvement of quality of construction of monolithic walls, improvement of strength and reliability.
