FIELD: construction.
SUBSTANCE: invention relates to construction. Forming system for constructing wavy monolithic arches consists of separate pneumo-framed arc elements enabling formation of a formwork on a separate limited concreting section able to be rearranged along the length of the structure being built. Design of the arc elements makes it possible to interconnect them by firmware of lateral extensions with eyelets enabling adjustment the pneumo-arcs axes pitch and, consequently, the longitudinal waves geometry. Pneumo-arcs interconnection design implies presence of an apron protecting the connection from dirtying with the fibrous-concrete mix. Pneumo-arcs-modules have flat support end faces providing a uniformly distributed load from the arc element onto the base. As a structural material of the wavy arch used is monolithic fibre concrete ensuring reduced shell thickness of the arch in comparison with tradition reinforced concrete.
EFFECT: invention can be used for constructing arches of a curved outline from monolithic fibre concrete.
