TUBULAR BAR JOINT CONNECTION TO CREATE THREE-DIMENSIONAL FRAME

摘要

FIELD: construction, particularly three-dimensional frames for buildings and building structures. ^ SUBSTANCE: joint connection comprises joint member including round discs pulled together with axial pipe. Joint connection also has tubular bars. Joint member is provided with ribs welded to discs and to axial pipe in radial directions and has enclosing rolled-on strips. Tubular bars comprise ears fastened with plugs and are connected to ribs by means of high-strength bolts through two covering plates. One covering plate is made as T-member. Joint connection is provided with inserts including two tube halves welded to tubular bar ends, namely to rolled-on strips. ^ EFFECT: increased load-bearing capacity and assemblage accuracy. ^ 4 dwg
