Antiseismic-Systems - Earthquake Protection Systems
Anti-seismic system placed in a shaft of a load-bearing structure
The main object of the hydraulic tie rod for construction projects of our invention along with its application method in the construction field for structural projects is to minimise the problems associated with the safety of structural projects such as buildings in the case of natural phenomena such as earthquakes, tornados and very powerful winds in general. According to the present invention, this can be achieved by a continuous pre-stressing (pulling) of both the roof of a large, geometrical part of the building structure which independent of the load-bearing structure towards the ground and of the ground towards the structure, making these two parts one body like a sandwich.
This pre-stressing force is applied by the mechanism of the hydraulic tie rod for construction projects, said mechanism mainly consisting of a steel cable penetrating free in the centre the vertical support elements of the structure, as well as the drilling length, beneath them. Said steel cable's lower end is tied to an anchor-type mechanism that is embedded into the banks (walls) of the drilling to prevent it from being uplifted. This embedding is attained due to the drilling hole being somewhat smaller than the exterior diameter of the completely opened anchor mechanism. Said steel cable's top end is also tied to a hydraulic pulling mechanism exerting a continuous uplifting force. This pulling mechanism comprises a piston, said piston reciprocating within a piston sleeve, connected to a pressure chamber beneath it. This pulling force, exerted on the top-end of the steel cable, by the hydraulic mechanism due to the hydraulic pressure originating from the rise of the chamber towards the piston, and the reaction in this pulling force originating from the embedded anchor at its other end generate the desirable compression in the construction project which in turn is tied to the ground and thus rendered resistant to the horizontal forces of an earthquake.

A Greek engineer developed a Tension Tie for building structures, which can be used to provide protection against the origination and development of failings in building structures, caused by earthquake and wind forces, and also to anchor any large structures, such as damns, houses, wind generators, bridges etc, into the ground (like a huge screw). This is achieved by a continuous prestressing (pulling) of both the structure towards the ground and of the ground towards the structure, making them into one body. The prestressing force is applied by means of a mechanical tension tie for construction.
