Description

Technical Field

[0001] The present application relates to the technical field of keel ceilings, and in particular to a light steel keel structure for a gypsum ceiling. Background Art

[0002] Steel keel ceiling, that is, the ceiling, especially the shaped ceiling, is made of light steel keel as the frame and then covered with gypsum board; light steel keel ceiling is divided into light steel keel ceiling for people and light steel keel ceiling for non-people according to the load-bearing capacity.

[0003] For example, a Chinese patent (publication number: CN213710068U) discloses a light steel keel ceiling, including a transverse tube, a longitudinal tube and a U-shaped connecting plate. The number of transverse tubes and longitudinal tubes is several, and the transverse tubes are vertically arranged between the longitudinal tubes. A U-shaped connecting plate is arranged at the connection between the transverse tubes and the longitudinal tubes. The U-shaped connecting plate is fixedly welded to the top of the transverse tube. The transverse tube and the U-shaped connecting plate form a through groove, and the longitudinal tube passes through the through groove. A positioning mechanism is arranged on the top of the U-shaped connecting plate, and the longitudinal tube and the U-shaped connecting plate are fixedly connected by bolts and nuts; right-angle hook plates are fixedly installed at the bottom of both ends of the transverse tube. The benefit of this application is that the U-shaped connecting plate provides an installation limit position between the transverse tube and the longitudinal tube, and at the same time has a positioning mechanism, which can be positioned before fixed installation to avoid disengagement, providing convenience for installation and fixing, and facilitating the installation and locking of bolts and nuts.

[0004] The above-mentioned light steel keel ceiling still has certain shortcomings. When the horizontal pipe and the longitudinal pipe are installed, the longitudinal pipe passes through the U-shaped connecting plate, the positioning sleeve is aligned with the positioning hole, the positioning rod is inserted into the positioning sleeve, and passed through the positioning hole to achieve positioning. However, since the positioning hole is through, the positioning rod is easy to fall into the inside of the vertical pipe when inserted into the positioning hole, resulting in inaccurate positioning. When the diameter of the positioning rod is slightly larger than the positioning hole, force is required to insert the positioning rod, which is not only time-consuming and labor-intensive, but also affects work efficiency. Therefore, the present application proposes a light steel keel structure for gypsum ceiling to solve the above problems. Utility Model Content
