Aluminum alloy window frame grouting reinforcement structure and construction method thereof

The invention relates to an aluminum alloy window frame grouting reinforcement structure and a construction method thereof. The aluminum alloy window frame grouting reinforcement structure comprises a plurality of sets of guard plates, the guard plates are matched with a window frame in length, each guard plate has certain elasticity, a notch is formed in one end of each guard plate in a concave mode, and the peripheral edge of the window frame is inserted into the corresponding notch; a wall body is provided with a mounting opening for mounting the window frame, the edge of the side, away from the notch, of each set of guard plates abuts against the inner wall of the mounting opening, and every two adjacent sets of guard plates are spliced in a sealed mode at the right-angle position of the inner side of each set of the mounting opening; and a grouting opening is concavely formed in the wall body on the horizontal upper end part of the window frame, the grouting opening communicates with the horizontal inner
