A ceiling frame joint structure comprises a first member and a second member each of which is in the form of an elongated, downward-facing U-shaped channel defined by a top wall and two opposite side walls to receive therein a portion of a bar member which constitutes the ceiling frame. Each of the first and second members comprises a middle section interposed between two opposite end sections and the side walls of the middle sections are removed to form notches which have such a size that the second member is receivable within the notches of the first member in an orthogonal manner to have the top wall thereof crossly overlapped under the top wall of the first member. A fastener penetrates through holes formed on the middle sections of the top walls to secure the two members together. Holes are provided on the side walls of both members to allow nails or screws to penetrate into the bar member received within the channels to secure the bar members within the first and the second members.
