CH keel and CHC keel are used as the skeleton material of the partition wall and have been promoted and used in the market. Figure 1 As shown, the existing CH keel is usually formed by rolling and bending a steel plate to form a continuous C-shaped groove structure 1a and an H-shaped groove structure 1b in sequence; Figure 2 As shown, the existing CHC keel is usually formed by rolling and bending a steel plate to form a continuous first C-shaped groove structure 2a, an H-shaped groove structure 2b and a second C-shaped groove structure 2c in sequence.

[0003] However, due to the continuity of the rolling process, the C-shaped groove structure 1a and the H-shaped groove structure 1b in the CH keel are connected by the folding structure 1c; the connection part between the first C-shaped groove structure 2a and the H-shaped groove structure 2b, and the connection part between the H-shaped groove structure 2b and the second C-shaped groove structure 2c in the CHC keel are formed by the folding structure 2d, and the folding structures 1c and 2d are both formed by folding two layers of steel plates, which increases the amount of plate used in the keel, resulting in higher production costs.
