METHOD FOR PRODUCTION OF FLAT AND SPATIAL CELLULAR STRUCTURES AND COMBINATIONS ON THEIR BASE Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: method relates to continuous production of flat and spatial cellular structures, reinforcement nets, and net-type structural systems. Technological process is carried out by stages in one or several parallel flows with subsequent transfer into one main flow. Material is unwound by pulling rolls, edges are cut off, end of subsequent roll is rigidly connected to end of preceding roll. Sheets are corrugated or profiled by bending in strip of row of holes into multiple-wave zigzag-like blank which is folded and connected into multilayer unit. This unit is stretched on plane, and configuration of obtained cellular structure is fixed. Produced structure is rolled on receiving drum, is cut into portions or is rigidly combined by corresponding sides with material coming from parallel flows. Aforesaid production method allows for manufacturing robust flat and spatial cellular structures and combinations on their base by means of single flow-process technology. Form-creation potentialities are widened within entire range of values of Gaussian curvatures. Possible is creation of structures with directed internal degrees of freedom. EFFECT: higher efficiency. 5 cl, 10 dwg
