METHOD FOR FORM REMOVAL FROM CONCRETE MASSIVE STRUCTURES Russian patent published in 2001 - IPC

Abstract RU 2172808 C1

FIELD: construction engineering; erecting massive concrete piers and other structures. SUBSTANCE: method involves removal of form and heat insulation. First form and heat insulation are removed from one of side walls of massive concrete structure. Then heat insulation is reinstalled on structure; in a certain time interval τ₁ form and heat insulation are removed from opposite side of concreted structure and then heat insulation is reinstalled. After that same procedure is made with two other opposite sides of structure. Time interval τ₁ is found from equation τ₁≥ m3τ, day, where τ is time taken to simultaneously remove form and heat insulation from one side of structure and to reinstall heat insulation on structure, m = 1±0,3 is coefficient of work conditions. EFFECT: reduced time required for form removal; provision for reuse of form. 6 dwg
