During connection, the screw C sequentially penetrates through the horizontal top of the main keel A, the horizontal surface of the auxiliary keel B and the through holes in the pressing sheets, and is fixedly connected with the pressing sheets E through the rotary screw C of the dovetail nuts D.

The screw C, the dovetail nut D, the pressing sheet E, the reed L or the spring are made of steel or plastic. The reed L is a trapezoidal reed.

A plurality of through holes are formed in the horizontal top of the main keel A and the horizontal surface of the auxiliary keel B and are arranged in a row, and the through holes are arranged on the same straight line.

The bottom end of the vertical side wall of the main keel of the light steel suspended ceiling is inwards bent in an arc shape, horizontally extended or upwards extended at an oblique angle.

Still include main pendant, main pendant includes pendant F, two hang muscle bolts G, hangs muscle screw rod D1, pendant nut C10 and pendant screw rod C3, main joist A passes through pendant nut C10 and pendant screw rod C3 and fixes at pendant F, and pendant F fixes on hanging muscle screw rod D1 through two hang muscle bolt G cooperations, connects the roof.

The utility model has the advantages that:

1) the main joist hangs the light locking of piece through the owner for through-hole is in a straight line on the main dragon, and the workman installs the false keel and only need unified interval installation, and the false dragon is decided to be in a straight line.

2) The connecting device has simple structure, convenient processing and low cost.

3) The connecting device is easy and convenient to install, the service life and the bearing capacity of the keel connecting piece are obviously prolonged, and various building scene requirements are met.
