Description

Technical Field

[0001] This utility model relates to the field of keel technology, and in particular to a CHC keel and wall structure. Background Technology

[0002] Keel is a building material used to support shapes and fix structures; it serves as the framework and base material for decoration and is widely used. CHC keel has appeared on the market as a partition wall framework material. This material offers excellent construction techniques for installing partition walls in special locations such as fireproof and soundproof walls, shafts, and tunnels in decoration projects. For example... Figure 1 As shown, existing CHC keels are usually formed by rolling and bending a steel plate to form a continuous first C-shaped groove structure 1a, an H-shaped groove structure 1b, and a second C-shaped groove structure 1c. However, due to the continuity of the rolling process, the connection between the first C-shaped groove structure 1a and the H-shaped groove structure 1b, and the connection between the H-shaped groove structure 1b and the second C-shaped groove structure 1d, are all formed by folding the edge structure 1d. The folding edge structure 1d is formed by folding two layers of steel plates, which increases the amount of sheet material used in the keel and results in higher production costs.
