With the work area cleared and the local building codes consulted, you’re ready to start the installation process. How exactly is it done? Let’s dissect the process.
Installing
The first step in installing your adjustable steel column involves:
- Adjusting the screw of the mono posts to a length slightly shorter than the distance between the footer and the load-carrying beam at the installation location.
- Once the column is positioned vertically with the adjustment nut and screw on the footer, tighten the screw to wedge the post firmly in place.
- You can make additional adjustments as needed during construction to maintain the floor level.
After installation, it’s crucial to verify that the adjustable steel column is securely supporting the intended load without any signs of movement or instability. Ensure the top and bottom plates are secured as well.
Finally, the concrete locks post adjustment screws should be either encased in concrete or damaged to prevent post-installation tampering. It’s also important to confirm that the column is mechanically connected to the floor for stability and proper load transfer. With these steps, including the concrete locks post adjustment, you should have a sturdy and reliable adjustable steel column installed.
How can we guarantee its durability? Here are some maintenance tips.
Ensuring Durability: Maintenance Tips
To maintain the durability of adjustable steel columns, you must follow a few key steps. First and foremost, protecting them from moisture is crucial to prevent rust and corrosion. You can accomplish this by applying rust prevention paint, which effectively finishes the columns and protects them against corrosion.
Addressing water problems at their source is also crucial because steel that stays wet can corrode over time, even with a coating. Using a thin piece of flashing, like copper or zinc-plated steel, under the column’s base is another effective method to prevent water damage.
Routine Inspection and Cleaning
Regular inspections and cleaning are critical to maintaining the structural integrity of adjustable steel columns. You should check the columns for rust or deterioration regularly, especially at the base where corrosion is more likely to occur. Also, ensure that the columns are plumb, level, and the top and bottom plates are securely fastened.
If a column exhibits more than minor surface rust that cannot be easily removed, replacing the column is recommended. For an added layer of protection, you can apply a corrosion-resistant powder coating, which forms a durable surface once cured under heat.
What happens if you face problems with your adjustable steel columns? Here’s how to tackle them.
Addressing Common Issues
Authorities do not approve two-piece steel columns, or telescopic posts, for permanent support; they classify them as temporary or additional support.
