MODULAR STRUTTING TOWER FOR CIVIL ENGINEERING AND CONSTRUCTION

摘要

The tower has a pawl pivotably mounted on a tenon (80) and forming a bolt. A back traverse opening (81) is arranged at a free end of an upper horizontal rail (61). Axes (A, B) are included in a same horizontal plane such that the tenon and the opening corresponding with adjacent to be assembled single-piece frames (6) are encased by a horizontal swiveling movement (R) of one of the frames relative to the other frame around a fulcrum pin (C). The swiveling movement is included in a safety perimeter (P) and the pawl is arranged to lock the tenon with the opening traversing in the perimeter. The pin is defined by its post segment (40).
