GEAR TO JOIN STRESSED REINFORCEMENT BUNDLES

摘要

FIELD: manufacture of construction structures and articles, specifically, manufacture of pre-stressed reinforced concrete articles. SUBSTANCE: gear to join stressed reinforcement bundles has coupling with one-side thread and threaded anchors with male thread of same direction located on butts in its space. Each threaded anchor has conical holes narrowing in direction from center of coupling where fixing members formed by wedge segments having groove in outer surface along arc of segment are mounted movably. Groove accommodates circular restoring member which cross-section does not exceed cross-section of groove. Thread of anchors and coupling can be trapezoidal or rectangular with formation of clearance between butts of protrusions and bottoms that is filled with grease. EFFECT: simplified design of anchor, decreased usage of metal and labor input to its manufacture. 1 cl, 3 dwgo
