Underfloor heating - "floating" pipes - or not on the floor?

Hello experts,

in our new building, the underfloor heating pipes have now been laid. However, in some places (especially in the corners) the pipes are suspended in the air... The pipes are under tension and are lifting the installed Flipfix panels.

In our case, the distribution of the underfloor heating for the ground floor is located in the basement, meaning all the pipes run through a shaft to the basement. Here the pipes rise extremely high and are under tension... Is this okay???
At the corners, I believe that the screed presses everything down. At the shaft leading to the distribution (the pipes all have to turn 90 degrees downward), it is almost impossible to push everything down with force.

Is it allowed for a gap to remain here?? Is this professional?
Or how can the pipes be fixed to the floor?

Regards, Christian

The screed will not press down your pipe. It "runs" underneath and stays there. It's clear.

Probably, an angled piece per pipe should have been installed at the transition from the shaft. I wouldn't press anything there. Read through the datasheet of the hose used, it will mention something about the minimum bending radius. From what you describe, I estimate that it is not being observed. In that case, I would order a work stoppage.

Smallest bending radius 5 x d according to DIN 4726

and what does that mean?

That means that if you form a circle from the pipe, this circle must be ten times as large as the diameter of the pipe. Such a circle now has a certain curvature. If you no longer form a whole circle but only bend the pipe around a curve, the pipe in the curve must not be more strongly curved than in your circle. Get an expert as soon as possible; to my ears, that does not sound good at all.

Photo? Enough staples attached?

As long as the bending radius is correct, the appropriate spots can be secured accordingly.

But actually, it only depends on the properly sized opening, so that the pipes can be cleanly routed to the next floor...
