How to deal with light steel keel walls: comprehensive analysis of construction steps and precautions
As a common form of partition wall in modern decoration, light steel keel wall is widely used because of its advantages such as lightness, environmental protection, and fast construction. This article will combine the hot decoration topics on the Internet in the past 10 days to provide you with a detailed analysis of the construction process, common problems and solutions of light steel keels.
1. Light steel keel wall construction process
| steps | Operation content | Things to note |
|---|---|---|
| 1. Basic treatment | Clean the walls and level the base | Ensure the base layer is firm and free of hollows |
| 2. Spring line positioning | Stakeout according to design drawings | Use a laser level to ensure accuracy |
| 3. Install the keel along the ground | Fixed bottom support structure | Moisture-proof treatment is required |
| 4. Install vertical keel | Arrange according to 400-600mm spacing | Use special keel pliers to fix |
| 5. Install the cross brace keel | Increase structural stability | flush with vertical keel |
| 6. Board sealing operation | Install drywall or other veneer | Leave 3-5mm expansion gap |
2. Top 5 recent popular issues (data in the past 10 days)

3. Detailed explanation of key construction points
1. Sound insulation solution
Recent search data shows that sound insulation is the pain point that owners are most concerned about. It is recommended to fill the keel cavity with rock wool (density ≥80kg/m³) and install it with staggered joints of double-layer gypsum boards, which can increase the STC sound insulation to more than 50dB.
2. Measures to prevent cracking
According to the hot discussion on the decoration forum, it is recommended to: ① Use special caulking gypsum at the joints; ② Use L-shaped whole boards for cutting corners; ③ Reserve V-shaped grooves between boards; ④ Use anti-cracking bandages to treat joints.
3. Material Selection Guide
| Material type | Recommended specifications | market reference price |
|---|---|---|
| Light steel keel | 75 series partition wall keel | 8-12 yuan/meter |
| gypsum board | 12mm fireproof board | 35-50 yuan/piece |
| Connector | Galvanized self-tapping screws | 15-20 yuan/box |
4. Common Misunderstandings and Professional Suggestions
Misunderstanding 1: The wider the distance between keels, the more money you save.
In actual construction, a spacing exceeding 600mm will cause the decorative panel to deform. It is recommended that the standard spacing of 400mm should be adopted for residential spaces, and the spacing can be appropriately relaxed to 600mm for commercial spaces.
Misunderstanding 2: Ignore expansion joint treatment
Many recent renovation rights protection cases have shown that failure to leave expansion joints is the main cause of cracking. During construction, a 3-5mm gap needs to be left and treated with elastic caulking agent.
5. Reference for acceptance criteria
| Project | Qualification standards | Detection method |
|---|---|---|
| Verticality | ≤3mm/2m | Detection by ruler |
| Flatness | ≤2mm/2m | laser level |
| seam treatment | No visible cracks | Visual inspection |
6. New construction trends in 2023
According to industry data: ① The utilization rate of prefabricated light steel keel systems increased by 35% year-on-year; ② The proportion of BIM technology applied to keel layout reached 28%; ③ The market share of environmentally friendly light steel keels exceeded 40%. It is recommended that owners choose products with green building material certification.
Summary: The treatment of light steel keel walls requires standardized construction processes and attention to detail. Through reasonable material selection, standard construction technology and strict acceptance, a wall system that is both beautiful and practical can be created. It is recommended that the owner choose a qualified construction team and supervise the process.
