Abstract
The tie rod for structural projects for the protection of structures for earthquake and wind is comprised of a cast iron base (7) which has a bolt (4) passing through a hole, which is surrounded by threaded ring (5) with handles (6). A base plate (2) that sits on the bolt and turns with a ball bearing. A steel cable (9) passes through all; the one end of the cable is fixed to the base (2) with bolts (3). The other end leads to a member with blades around it (10), (12), (13), (14) which open and close around the member (17) with the help of bars (11) connected around the axis of the member with pins. To the other end, they are connected with pins to the blades. The rod presses the structure to the ground by a bolt connected to a cable which pulls a member (17) with blades which open against the sides of a hole drilled on the ground and pull the building towards the ground decreasing torque created by the forces of an earthquake or the wind. It is used on buildings with a frame, continuous building, wood frame houses with storm problems, cable bridges, loose ground slopes, etc.
