FIELD: building, particularly three-dimensional structures used as cover and floor panels in civil, public and industrial buildings. ^ SUBSTANCE: structure has thin-walled three-dimensionally shaped members of unified shapes. The members are made of thin-walled roll steel with thickness t=0.5-3.0 mm. Steel strips are bent in opposite directions along right-handed and left-handed screw lines and connected one to another along congruent edges. Each next member to be connected to the structure is bent in opposite direction in comparison with previous one. ^ EFFECT: possibility of in-line building structure production by cold profiling with the use of wasteless perforation, increased labor productivity, reduced material consumption and labor inputs, elimination of separate rods connection in structure units, reduced number of location and starting marks, increased assemblage processibility. ^ 4 dwg |
