Abstract
Способ монтажа шпренгельной фермы, включающий объединение гибких поясов со стойками, закрепление стоек на балке, подъем фермы и ее закрепление в проектном положении, а также создание предварительных напряжений в поясах, отличающийся тем, что стойки фермы, закрепленные за балку монтажными шарнирами, разворачивают вдоль ее оси, а предварительные напряжения в поясах создают путем синхронного поворота стоек вокруг шарниров до достижения стойками ортогонального положения относительно балки.A method of mounting a truss truss, including combining flexible belts with racks, securing the racks on the beam, raising the truss and securing it in the design position, as well as creating prestresses in the belts, characterized in that the truss racks fixed to the beam with mounting hinges are deployed along it axis, and prestresses in the belts are created by synchronously rotating the racks around the hinges until the racks reach an orthogonal position relative to the beam.
