Question regarding basement wall

[Oskaris]

Have torn down studs inside the outer wall in the basement of our 70s house and then pipes/spacers appear according to the picture. Does anyone have any idea what it is? These are all over the wall, though a bit difficult to see in the picture.

In the sleeves are probably the remains of the reinforcement bar that went through the formwork. The purpose of the rods was to hold the form together during the casting process.
I have only seen smooth reinforcement bars, but perhaps there was a threaded variant given the design of the sleeve.

In the sleeves, there are probably the remains of the bistål that went through the mold. The task of the bars was to hold the mold together during the casting itself. I've only seen smooth bistål but maybe there was a threaded variant considering the design of the sleeve.

I looked at the pictures again and became very doubtful about my assumption. I can't quite make sense of the wall construction itself. It would be fun if someone knows...

Looks like insulation of the type Rockwoll Elefantmatta is there, if so, there are spacers to avoid compressing the insulation with the wall material when it is fastened in place.

Took some closer pictures and if you unscrew the casing, there's a spring the casing is screwed into, seems complicated😅

??? Fjäder. Can it be that the outer wall cladding should be able to move then. How was it attached from the beginning of your job. What does the wall consist of that the springs are attached to, or is there some kind of bracket that it's attached to, and the bracket in turn attached to the wall. You can cut out a piece 150X150 mm and lift it out, just put it back then.

??? Spring. Could it be that the outer wall cladding needs to be able to move then. How was it attached from the start of your job? What is the wall made of where the springs are attached, or is there a bracket that it sits in, and the bracket in turn is attached to the wall?

They appear to be cast in the concrete, was planning to cut them off and then either plaster or frame the wall, but now I'm unsure if they hold something on the other side which is actually underground so nothing should collapse 😅

Originally, it was cladding made of what I believe was Masonite and vertical studs attached to the semi-cast horizontal studs.
