A joint structure for a reinforcing rib of an injected frame of a door leaf, comprising:

• a main door leaf with a rectangular shape;
• two complementary halving injected frames;
• and
• a glass pane having multiple layers of glass, wherein the main door leaf has an opening for said two complementary halving injected frames and the glass pane fixedly assembled thereon;
• said two complementary halving injected frames each have a hollow frame structure including an inner edge and an outer edge,
• said two complementary halving injected frames have on their respective reverse sides, a male tenon reinforcing rib and a female tenon reinforcing rib formed in mutual arrangement with a corresponding female tenon reinforcing rib and a male tenon reinforcing rib, respectively, of the complementary one of said two halving injected frames,
• each male tenon reinforcing rib has a footing rib connected to the reverse side of the corresponding halving injected frame and a tenon rib superposed on a top of the footing rib, which tenon rib is provided with a positioning groove and a tenon nose, and
• each female tenon reinforcing rib comprises a fixing rib and a leading rib both connected to the reverse side of the corresponding halving injected frame, the fixing rib and the leading rib being disposed at a distance to form a tenon groove that supplies room for the tenon rib of the male tenon reinforcing rib, from the complementary halving injected frame, to be inserted therein, and the fixing rib is provided with a positioning groove notched on a surface directed toward the tenon groove and a female tenon head next to the positioning groove.
