ANCHOR UNIT SECURED WITH BINDER

摘要

FIELD: mechanical engineering. ^ SUBSTANCE: anchor unit comprises anchor rod secured with a binder in the drilled opening in the member of a structure. The anchor rod comprises several conical sections whose cones diverge in the direction to the end that is set into the opening and several cylindrical sections that separate the conical sections. The length of the cylindrical sections ranges from half length to double length of the adjacent conical section. The diameter of the cylindrical sections is less than the outer diameter of the anchor rod by a factor of 0.5-0.75. ^ EFFECT: enhanced reliability. ^ 6 cl, 4 dwg
