Abstract

Изобретение относитс  к строительству и предназначено дл  закреплени  напр гаемой арматуры при изготовлении преднапр женных строительных конструкций в заводских или построечных услови х, а также при проведении различных исследований арматуры в лабораторных услови х. Цель изобретени  - повышение надежности закреплени  арматуры при ее нат жении. Анкерное устройство содержит установленный на арматуре самозаклинивающий захват 2 с опорным элементом 4, шпильки 5, закрепленные в опорном элементе, и траверсу 6, насаженную на шпильки. В устройстве между траверсой 6 и захватом 2 установлен дополнительный самозаклинивающийс  захват 3, расположенный на арматуре под углом 180° к первому захвату на рассто нии, обеспечивающем сохранение устойчивости ограниченного захватами участка арматуры от усили  сжати , равного по величине усилию нат жени  арматуры. Обжатие зажимов вначале производитс  в силовой раме при помощи домкрата, а сохранение этого состо ни  достигаетс  за счет упругих сил участка арматуры, расположенного между захватами. 2 ил.The invention relates to construction and is intended to secure tensioned reinforcement in the manufacture of prestressed building structures in factory or construction conditions, as well as during various studies of reinforcement in laboratory conditions. The purpose of the invention is to increase the reliability of fixing the reinforcement during tension. The anchoring device comprises a self-jamming grip 2 mounted on the reinforcement with a supporting member 4, studs 5 fixed in the supporting member, and a traverse 6 mounted on the studs. In the device between crosshead 6 and gripper 2, an additional self-jamming gripper 3 is installed, located on the reinforcement at an angle of 180 ° to the first gripper at a distance that ensures the stability of the gripping section of the reinforcement limited by the grippers from compressive force equal to the tension of the reinforcement. The compression of the clamps is first performed in the power frame with the help of a jack, and this state is maintained due to the elastic forces of the section of reinforcement located between the grippers. 2 Il.
