Mark the cavity and stone layout as per approved drawings.
Determine the position of the L- bracket as per approved
drawings.
Fix the L- bracket by using S/S 316 M 8*80 – shield bolt
anchor for block wall, S/S 316 M8*80- through bolt anchor for concrete wall or,
S/S 8 *80 – HEX bolt for steel structure.
Apply the torque of 18 Nm and do spray paint on bolt head to
indicate that the bolts are checked & tightened.
Position the aluminum Q- profile as per the cavity required
on the drawings. And fix the Q-profile by SS 410 RKY façade screw φ
6.3 x 25. Placement of the Q- profiles should be at every stone joint and
center part of the stone.
In accordance with the stone joints, mark and fix the
aluminum hangers (single hanger for the center part of the stone / double
hangers for the stone joint areas) to the Q- profile by using SS 410 RKY façade
screw φ
4.8 X 32.
60 mm insulation sheet must be tightly botted together and
