ᐅ The crossbeam is supported on only one side.

Hello everyone,

We have taken over a house built in 1978. Above the kitchen, there is a small storage room where an old heat pump used to be installed. The opening in the ceiling is now relatively large, and a crossbeam of the composite concrete slab seems to rest on only one wall with about 15cm (6 inches) of bearing length (at least that’s what I assume). I could not identify a second support.

Is this a structural concern? And what measures would be necessary here?

I have attached a photo.

It has lasted since 1978, over 50 years. What do you want to pick at? It will be as it is meant to be.

Without knowing the full context of the situation, it is naturally very difficult to make a relevant statement about the structural stability. The main beams of the hollow-core slab have obviously been cut and are only supported on one side, which is completely illogical from a structural engineering perspective. An architect or structural engineer should examine the construction before you proceed with renovations based on a “keep going – it has held for ... years” approach.

The house may have been built in 1978, but the near-collapse is hardly proven to have been stable since then. Unfortunately, the only thing visible in the picture is that it is not as it should be. Siemens air hooks only work reliably over time under very specific conditions: bought on a full moon from Wolpertinger virgins in Schilda and set with homeopathic remedies. That is the accepted rule of hope.
