What is the composition of light steel keel ceiling construction?

Use light steel keel as frame, and then cover it with gypsum board.

Light steel keel can be divided into U-shaped keel, C-shaped keel and L-shaped keel according to the keel section. According to the specifications, it is divided into D60 series, D50 series, D38 series and D25 series.

The keel forms the suspended ceiling skeleton, which is used to install the cover panel and bear the weight of the cover panel. The keel is made of thin-walled steel strip by rolling. Accessories include vertical hangers, longitudinal connectors and planar connectors. The vertical hanger of the big keel is installed at the lower end of the boom to hang the big keel, and the vertical hanger of the middle keel is installed on the big keel to hang the middle keel.

The small keel vertical hanger is installed on the big keel for hanging the small keel. Each longitudinal connector is used to extend the large, medium and small keels respectively. Plane connectors are used for right-angle connection of keels. The cover panel is installed under the small keel and can be made of paper gypsum board, decorative gypsum board, calcium-plastic board, mineral wool board, asbestos cement board, etc.

1, V-type hanging keel light steel keel

V-shaped hanging keel, also known as card keel, is the national patent number of decorative materials (main dragon-ZL 00263956.4; Dragon -ZL 0437+0). In terms of design and manufacture, the traditional ceiling keel is broken.

Moreover, high-quality snowflake board is used as raw material, which has strong fireproof, antirust and anti-aging properties, and all functions have passed the national inspection (GB11981-2001), so it is convenient to construct and has outstanding effect, and is widely used in modern decoration engineering.

The two side walls of the V-shaped groove are symmetrically and orderly provided with anchor hooks, which can form an English or metric combination with the auxiliary keel. The connection between the main keel and the auxiliary keel needs to be locked with 8 cm screws to make it more firm and durable.

2. Light steel keel of partition wall

Light steel keel is widely used in luxury villas, high-end hotels, office buildings and shopping malls. It is durable and corrosion-resistant, and it is also widely welcomed by the construction unit and construction unit in price, which reduces the concern about quality during construction.

And frequent maintenance caused by material quality problems in the use process, which greatly reduces the engineering construction cost and various troubles caused by maintenance in the use process.
