<p>A foundation raft is constructed by joining the modular members (2,3) of a form being completed via drilled external lateral plates (6), by inserting self-centering clamps (8) in oblong holes assisted by a stabilizer fitted with security pins and a suitable anchorage (11) which secure the form to the ground. The faces of the modular members form a right-angle dihedral and angles having angular reinforcements (4) which join two faces of dihedral. The reinforcements are provided with oblong orifices (7) which provides resistance to pressure exerted by setting material on all upper plates (6') and on the whole periphery of the modular members to protrude adjustment legs (5) which center layout and positioning template.</p> |
