JOINING MEMBER FOR WOOD STRUCTURES

摘要

construction engineering; metal joining members with stamped teeth. SUBSTANCE: member used for joining members of wood bearing and frame building items and structures has plate with sockets and single-sided teeth arrangement; teeth are bent sequentially in each transversal row in opposite directions and spread in their base; side edges of spreading are made in the form of concave line on tooth length up to section of constant width which equals 0.5-0.6 of tooth length; tooth pointed area amounts to 0.20-0.25 of tooth length; ratio of tooth pitch to distance from longitudinal row of teeth is 3.5-4.5; adjacent teeth in each transversal and longitudinal rows are bent in opposite directions relative to each other with deflection from vertical through up to 5 deg. in longitudinal axial direction. EFFECT: improved bearing capacity; reduced metal input; enhanced resistance of plate to probable erection thrusts. 4 cl, 4 dwg
