Description
и присоедин ют к ним хомуты 4. После этого включают домкраты на рабочий ход и прит гивают зат жки / хомутами 4 к вершинам шрренгельных стоек 5, тем постепенно напр га зат жки и одновременно контролиру возникающие в них усили .and attach the clamps 4 to them. After that, the jacks are turned on the working stroke and the pulls / clamps 4 are drawn to the tops of the shrrengel racks 5, thereby gradually pulling on the hooks and at the same time controlling the forces arising in them.
После достижени требуемой, величины усили нат жени зат жку в прит нутом положении креп т к вершина.м ш.прен.гельных стоек, а домкраты снимают с конструкции .After the required tension is reached, the tension in the tightened position is fastened to the apex of the gel front struts and the jacks are removed from the structure.
Устройство нат жени состоит из подвижных хомутав 4, прикрепленной к т ;жам траверсы упора 6 домкрата, парных, параллельных между собой элементов стойки 7 и площадки упора 8 домкрата. После осуществлени захвата зат жки 1 хомутами 4 производ т установку домкрата , опира нижний конец его на траверсу упора 6, а верхний - на площадку упора 8. При раздвижном рабочем ходе домкрата цроисходит опускание вниз траверсы упора и хомутов 4 и вследствие этопо прит гивание зат жки / к вершине шпренгельской .стойки 5, т. е. « .площадке упора 8. Зат жка / в процессе прит гивани свободно перемещаетс в вертикальной плоскости между парными параллельными элементами 7. Зат жку / в окончательном прит нутом положении фиксируют посредствомThe tensioning device consists of movable clamps 4 attached to t; y traverse the supports of the jack 6, paired, parallel to each other elements of the rack 7 and the platform of the jack 8 of the jack. After the fastening of the tightening with 1 clamps 4, the jack is installed, its lower end is supported on the traverse of the stop 6, and the upper end is placed on the stop 8. At the sliding working stroke of the ram, the traverse of the stop and clamps 4 descend down and due to this it is attracted / to the top of the Sprengel rack. 5, i.e., "the seat of the stop 8. Tightening / in the process of attraction is freely moving in a vertical plane between the paired parallel elements 7. Tightening / in the final attracted position is fixed by

Описанное техническое решение позвол ет снизить трудоемкость нат жени .The described technical solution allows to reduce the laboriousness of tension.
