Abstract
Abstract 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.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
229 words
A ceiling frame joint kit for connecting ceiling bars, the joint kit comprising: a first joint member including a pair of substantially U-shaped channel portions, each channel portion adapted to receive a ceiling bar and each having a pair of side walls and a connecting wall arranged between the side walls, and a substantially planar portion arranged substantially between the connecting walls to define a first notch transversely between the chapel portions; a second joint member, separate and apart from the first joint member, including a pair of substantially U-shaped channel portions, each channel portion adapted to receive a ceiling bar and each having a pair of side walls and a connecting wall arranged between the side walls, and a substantially planar portion arranged substantially between the connecting walls to define a second notch transversely between the channel portions: a joint fastener for securing the first joint member to the second joint member such that the first and second joint members are offset approximately 90° from one another; and at least one bar fastener for securing a ceiling bar received by one of the respective channel portions of the first and second joint members; wherein the first notch defines a distance sufficient to allow the second joint member to be adjusted relative to the first joint member when the first and second joint members am in an assembled state.
