Hi!
I'm in the process of building a house and have noticed that the builder has made too small an opening for the water meter cabinet in the load-bearing wall (15cm leca).
So now there is only an 18cm bearing on one side and about 1m on the other side.
Ideally, the beam would have been inserted into the 25cm wall and had plenty of bearing there, but that's not the case now. What are my options?
Finja recommends at least 25cm. The wall is bricked, rafters are attached in 45-degree lath, and concrete tiles are laid.
Is it possible to replace/move the beam?
Either you extend the support length with a steel or wooden construction, or you calculate it with the current conditions to see if it might work anyway.
Now there's no possibility to extend because that's where the water distribution cabinet is. Unfortunately, it's directly under the bathroom on the second floor, so the load is greater than normal. But if one were to place a 3m beam under the slope, so you get 25cm support on the thicker wall and support for the ceiling there? Then the beam that's there now would only support the lecan lying between the beams, wouldn't that work?
I don't know exactly how the lecablock manufacturers reason. Generally speaking, I think they want large bearing surfaces to compensate for the stone's limited compressive strength. I suspect that in your case, it might work well with just an 18 cm bearing surface, but in such situations, you should follow the manufacturer's instructions; otherwise, it will be difficult to make a claim. However, I find it hard to imagine that it couldn't be solved in some way. Can you upload a photo of the corner in question?
I'm more worried about the roof falling down than making a complaint.
That was before the blocks were knocked out. But it had been sawed. The whole beam is fixed and it's not easy to change that beam. Therefore, I was thinking if one could saw the edge and then chop off the top layer (3m) and then place a new beam with a bearing on the 25cm wall, it should support the weight from above, while the already embedded beam would only take 5 layers of leca.
