In construction, thin-walled reinforced
concrete spatial structures are used both
for unique roofs of large-span buildings and
for mass buildings of the pavilion type and
small architectural forms. The most serious
obstacle to the widespread application of
economical thin-walled reinforced concrete
structures is the shortcomings of the technology
used for the manufacture and installation
of prefabricated shell elements. The
method of bending just formed flat flexible
plates to give them a curved shape is one
of the most promising technological methods
that allow you to abandon the use of
expensive metal forms of complex curved
outlines, significantly simplify all production
processes.
The article describes the experience of
research and development of structural decisions
for spatial structures of building roofs
with the use of unified rhombic elements
made by the method of bending a flat just
formed sheet on a flexible formwork.
