UNIT IF JOINT BETWEEN VERTICAL BUILDING MEMBER AND HORIZONTAL CAST-IN-SITU REINFORCED-CONCRETE MEMBER Russian patent published in 2002 - IPC

FIELD: construction engineering; applicable in erection of cast-in-situ and precast-cast-in-situ structures. SUBSTANCE: unit of joint includes table fastened to column for casting of horizontal cast-in-situ reinforced-concrete member and additionally has anchor made in the from of one or several rods secured to column on side of table. In this case, anchor cross-section area equals to cross-section area of longitudinal tensile reinforcement. Anchor length is not more of one fourth of reinforced-concrete member span and not smaller than length of anchorage, and distance Z between anchor gravity center and table is determined by relationship Z=H-a'-K*d, where H is distance from table to upper plane of reinforced-concrete member; a' is thickness of upper protective layer; k is parameter varying within 2≥K≥0,5; d is diameter of anchor rods and longitudinal tensile reinforcement. EFFECT: higher reliability of joint unit reduced consumption of material, labor and power resources. 3 cl, 6 dwg
