摘要：: A prefabricated structure for a composite window apparatus using different frame materials.;The sides of the corners of adjacent first window frames and adjacent first sash frame which made of synthetic resin are punched, the punched parts of the first window frames, the punched parts of the first sash frames and the parts of the angle pieces are bent inwardly. When the punched parts of the angle piece are bent into the corner piece, the window frame compression flanges of the first window frames are pressurized by the angle piece and the corner piece, and the sash frame compression flanges of the first sash frames are pressurized by the angle piece and the corner piece, so that the corners of the first window frames and the corners the first sash frames are connected to respective angle pieces and corner pieces.
主权项：: 1. A prefabricated structure for a composite window apparatus comprising a window frame including an inner first window frame (20) made of synthetic resin and an outer second window frame (30) made of metal and connected with the inner first window frame (20), wherein the inner first window frame (20) having both ends cut at 45 degrees includes a corner piece path (23) and an angle piece path (24) which are lengthwise formed inside the inner first window frame (20), with window frame compression flanges (22) being lengthwise formed between the corner piece path (23) and the angle piece path (24) and protruding into an interior of the inner first window frame (20) from each of a first inside wall and a second inside wall of the inner first window frame (20), the window frame having an assembled state, wherein the corner piece paths (23) and the angle paths (24) of adjacent inner first window frames (20), positioned horizontally and vertically, receive a corner piece (70) and an angle piece (80) both made of metal, and the window frame having a secured state, wherein the angle piece (80) includes apertures and punched edges (81) abutting the apertures of the angle piece (80) and wherein the punched edges are bent towards, and into, the corner piece (70), such that the bent punched edges press against the window frame compression flanges (22) so that corners of the inner first window frames (20) are forcibly connected with the angle piece (80) and the corner piece (70) so as to secure the inner first window flames (20), and wherein the corner piece (70) includes receiving grooves (71) formed at an outer surface of the corner piece, wherein the apertures are opposite the receiving grooves and the angle piece (80) includes the punched edges (81) that are bent towards and forcibly connected with the receiving grooves (71) of the corner piece (70), such that in the assembled state the corner piece and the angle piece are removably received and in the secured state the corner piece and the angle piece are irremovably secured in place.
