CONNECTION UNIT TO CONNECT REINFORCED CONCRETE COLUMNS

FIELD: construction, particularly to connect columns, preferably having rectangular cross-sections, for composite building or building structure skeleton erection. ^ SUBSTANCE: connection unit includes coaxially arranged lower and upper columns, protruding longitudinal load-bearing reinforcement bars of lower column arranged between column ends and connected with each other and projected loop-like reinforcement bars of upper column. Connection unit also has projected loop-like reinforcement bars of upper column defining U-shaped members. U-shaped member legs abut against protruding longitudinal load-bearing reinforcement bars of lower column and fixedly connected thereto. Traverses of U-shaped member adjoin upper column end. Projected loop-like reinforcement bars of upper column extend for the full distance between the columns and made of paired L-shaped members arranged so that horizontal arms thereof face each other in planes passing through axes of protruding longitudinal load-bearing reinforcement bars of lower column and abut upon above bars. ^ EFFECT: increased technological efficiency, strength and reliability. ^ 4 dwg
