Hello everyone,
We are currently in the final construction phase and have had a laundry chute installed retroactively in DN300 from the upper floor down to the basement. It passes through 3 levels (2 ceilings) and was concreted into each respective ceiling. The DN300 pipe was pushed through the 35cm (14 inch) wide utility shaft before the screed was applied.
I have read a lot online about clamps, decoupling, sound insulation, etc., and now I’m a bit unsure. Maybe you can help me:
Current situation:
DN300 pipe consisting of 3 segments of 1 meter (3.3 feet) each plus a branch (DN300/DN300) for the chute opening. These 3 pipe segments were concreted into 2 concrete ceilings (done by the developer).
Our idea now was to add 2 more 1-meter (3.3 feet) segments onto the branch on the upper floor to keep the option open for another chute opening in the attic later on. However, the question arises: how to fix these? Clamps would be difficult because the shaft is only lined with drywall and there is no masonry wall around the pipe. We could build some support on the attic floor / upper floor ceiling, but clamps might not work well there either.
I believe that with about 5 meters (16.4 feet) of DN300 pipe, the two concreted points are not enough. What do you think? We are talking about approximately 50-60 kg (110-132 lbs).
Also, the question is whether the developer decoupled the pipes? I suspect not, which I think could be a major problem.
I often read about using rock wool or sheep wool for insulation, but I’m not sure exactly where it should be applied—only before concreting (between concrete and pipe?), or around the entire run of the pipe?
Thank you all very much.
I’m really out of ideas.
