Abstract

In architectural and construction system “Monofant” a self-supporting skeleton consisting of a spatial curvilinear framework and unrecoverable hollow-core inserts made of expanded polystyrene was used to erect buildings and structures of curved shapes from reinforced concrete lightweight structures. For this, an internal, non-removable formwork of complex shape makes up given geometry of the structure and becomes a certain screen on which a shotcrete mixture is sprayed. The problem of creating a technology for manufacturing polystyrene inserts for the erection of cylindrical shells has been solved. At the same time we achieved reducing the waste while cutting a flat rectangular sheet of expanded polystyrene and obtaining the minimum number of elements in the assortment for manufacturing triangular inserts used to produce a screen that provides shotcreting curvilinear reinforced concrete structures with the method of sprayed concreting. The obtained results confirm the effectiveness of using lightweight “Monofant” system designs that have a reduced width of not more than 40-50% from the structures with solid width.
