The invention provides a double-layer ceiling keel system comprising screws, perforated angle keels, double-layer lifting boxes, upper wide keels, lower wide keels and ceilings. Each screw is arranged vertically; the screws vertically penetrate slotted holes to horizontally and transversely lift the perforated angle keels through nuts; connecting holes of the lifting boxes are connected with the slotted holes of the perforated angle keels through bolts; the upper wide keels and the lower wide keels are provided with C-bends on two sides respectively along the extension direction, the width of each upper wide keel is equal to the horizontal side of each top box, and the width of each lower wide keel is equal to the horizontal size of each bottom box; a first assembly portion of each lower wide keel is connected with a first mounting portion of the corresponding double-layer lifting box; a second assembly portion of each upper wide keel is connected with a second mounting portion of the corresponding double-layer lifting box. The double-layer ceiling keel system is attractive in structural appearance and capable of assisting in routing and lighting.
