THERMOSETTING FORM Russian patent published in 2002 - IPC

FIELD: construction engineering; erecting monolithic concrete buildings. SUBSTANCE: thermosetting form with non- uniform distribution of heat throughout surface has deck, deck-mounted heater built around carbon fiber material with insulating layers. Zigzag-shaped resistive layer of electric heater has vertical and horizontal strips; width of vertical strips reduces from middle to edges. Width of horizontal strips is constant throughout entire length of resistive member and equals geometric mean of width of first from middle and last strips. Heating areas formed in the process are heated differently degree of heating increasing from middle to edges on both sides. EFFECT: provision for loss compensation through ribs and joints. 3 dwg
