PROCESS OF ENCASEMENT OF MONOLITHIC REINFORCED CONCRETE BUILDING STRUCTURE EXTENDED IN AREA IN CONCRETE Russian patent published in 2003 - IPC

FIELD: construction industry. SUBSTANCE: novelty of process consists in arrangement of expansion-contraction joints over entire width of grip and over entire thickness of concrete layer without violation of continuity of reinforced cage prior to laying concrete in forms dividing grip along its long side into internal, end-free and end-not free sections held rigidly by butts. Length of internal and end-free sections is equal to L, length of end-not free sections is L/2. Value L is found from condition 15≥L≤kh where h is width of grip, m; k = 0.8-1.5 is correction factor depending on local conditions. EFFECT: prolonged service life and quality of erected structure by reduced crack formation. 1 cl, 8 dwg
