Description

Technical Field

[0001] The utility model relates to the technical field of external corner keels, in particular to an external corner keel corner plug-in piece. Background Art

[0002] The light steel keel is a building metal skeleton rolled by a cold bending process with high-quality continuous hot-dip galvanized strip as the raw material. It is a basic material applicable to the styling decoration of the roofs of various buildings, the internal and external walls of buildings, and the grid ceiling. The light steel keel is generally used for non-load-bearing walls with light-weight plates such as paper-faced gypsum board and decorative gypsum board as the finishing surface and the styling decoration of the roofs of buildings. The light steel keels used are generally batch alloy profiles laid vertically and horizontally to form a planar grid shape and fixed in shape through keel hanging parts.

[0003] Existing light steel secondary keels are usually used in combination with external corner keels. To fit the existing keel building specifications, the external corner keels are often bent, and the corners may break due to deformation, with limited stability. Especially when additional secondary keels need to be installed at the corners, the additional load on them further affects the stability of the corners.
