We Claim:

1. A system for wall to wall connection for precast shear walls, the system comprising:

a plurality of horizontal and vertical reinforcement bars configured within the precast shear wall, the reinforcement bars provided with spacing there between;

a plurality of connecting tubes fixed between the spacing provided between the reinforcement bars;

a plurality of openings provided between the plurality of connecting tubes;

aplurality of grout tubes fixed abovetheplurality of openingsin order to grout the openings after completing confection of the shear walls;

a plurality of connecting bars capable of being inserted within the connecting tubes of the precast shear wall, when erected,

a connecting device inserted through the openings to grip the connecting bars; and

a driving device to supply power to the drive for causing rotation of the drive and thereby sending the connecting bar in a translational motion from the first shear wall to the second shear wall.

2. The system for wall to wall connection for precast shear walls, wherein the connecting tubes are fixed to the reinforcement bars using a plurality of holdfast.

3. The system for wall to wall connection for precast shear walls, wherein the plurality of openings are formed by the spacing of the reinforcement bars.

4. The system for wall to wall connection for precast shear walls, wherein the connecting device comprises at least two structural plates, at least two idlers, adriveand at least two adjustment screws.

5. The method for connecting precast shear walls, the method comprisingstepsof:

fixing connecting tubes in the shear walls at pre-defined locations, wherein theconnectingtubescomefront to front in theshear walls,when the shear walls are placed next to each other;

placing connecting bars in the connecting tubes of the first shear wall when thefirst shear wall iserected;

erecting the second shear wall next the first shear wall, in order to perfectly match the connecting tubes of the second shear wall to the centrelines of the connecting tubes of thefirst shear wall ;

fitting a connecting device at opening in thefirst shear wall to grip the connecting bar;

rotating head of the driving device thereby sending the connecting bar in a translational motion from thefirst shear wall to the second shear wall; and

groutingthe openings and gap between thewalls.
