I had a couple of builders at home who remodeled from two bedrooms into one larger room, the wall between was load-bearing and was relieved with steel posts 70x70 and HEB-beam 160.
One of the posts is in the exterior wall, the other post is in the interior wall.
No issues with that.
The posts have at the bottom a steel plate 170x130x10 mm onto which the posts are welded. The base of the post is attached to the top of the crawl space concrete beam. Thus, everything is secured and anchored to the foundation beam.
Built according to the construction drawing.
All good so far, but it turns out that the steel base and post literally suck up cold (today 11.0 degrees) from the crawl space. The two posts are built-in, but I removed the wallboard at the exterior post because I was going to run a couple of electrical pipes and junction boxes there. I then discovered that behind the post towards the exterior wall's insulation it was very wet along the entire post. The post had been covered only two to three weeks.
Insulating around the post base is impossible due to the concrete beam and the tight fit between the concrete beam and the post base which cannot be changed.
The first thing you think of is wrapping a heating cable from the floor space around the entire post and upwards. This should then be controlled with sensors and thermostat and connected to a residual current device and 230V. Everything should then be built in without the slightest control of the heating cable.
As a small electrician, I don't think you are allowed to lay heating cable near the inner wall just like that. It probably has to be preceded by conduit pipes, etc., and then you lose the close fitting that is needed. And how do I know this will prevent future condensation? There may also be cable problems.
It can be added that a window is to be installed right next to the steel post.
Please, help me come up with a good solution to this, the construction has stalled and time is passing. I have checked around the forum but find nothing similar to this.
Sending a couple of pictures.
Post against exterior wall, built-in post interior wall, post base in the floor, post base on concrete beam in foundation.
Unfortunately having trouble uploading pictures, will try another time.
EDIT 1
Now the pictures work!
Hi Örnis... it's been a few years now since your post... wondering if you came up with a good solution for the beam? We are building new with a similar solution and want to avoid problems with condensation and cold drafts... all tips are welcome.
