The prefabricated infill wall system with hollow heat preservation structure as claimed in claim 1, characterized in that the embedded connecting piece (5) is a square steel plate with a hole in the center, the diameter of the hole is adapted to the diameter of the vertical rod (185) of the L-shaped connecting end, and the embedded connecting piece (5) and the vertical rod (185) are fastened through nuts.
4. A method of constructing a prefabricated infill wall system with a hollow insulating structure as claimed in claim 1, comprising the steps of:
step one: spring wires, ejecting position wires of the prefabricated filling wall (16) in the square structure;
step two: a mortar layer for slurry connection is arranged on the lower frame beam (6), and a prefabricated filling wall (16) is hoisted through a hoisting ring (17);
step three: fixing the L-shaped connecting end and the embedded connecting piece (5) of the frame column (3) by nuts, and inserting the embedded positioning piece (7) on the lower frame beam (6) into the lower positioning hole of the concrete shell to ensure the embedded stability; after the prefabricated filling wall (16) is hoisted, the lower part of the prefabricated filling wall (16) is fixedly connected with the lower frame beam (6) through a mortar layer preset in the second step;
hoisting the upper frame beam (4) and reliably connecting the upper frame beam with the frame column (3);
step five: the plate seam treatment, wherein a separation distance of at least 20mm is reserved between the prefabricated filling wall (16) and the upper frame beam (4) and the frame columns (3) on the left side and the right side respectively; stuffing the gasket material (15);
step six: and (3) pointing the edge position by using building sealant to form a sealant layer.
