Aluminum Embedded on the Concrete (Window) 3

[juniorfacadeengr]

Hi,

I hope somebody can help me. I'm a junior facade engineer and I'm wondering if this design is feasible? The aluminum is embedded on the concrete and there won't be any mechanical fixing. The window is 1200mmHx850mmW in size.

Thank you in advance!

Definitely not recommended.
1. You typically want to avoid embedding aluminum in concrete due to corrosion concerns.
2. The alignment will never be correct.
3. You'll never get the concrete to consolidate properly inside that profile.
4. Contractors will hate you.
5. No adjustment possible after casting.

I really appreciate your advise. But just wondering does it have any structural concerns?

never place aluminum into concrete
Consolidation issues
Construct ability issues

Yes, those are all structural concerns. I.e., the window will probably fall out and smash someone due to reasons #1 and #3.

Mechanical attachment is pretty much the only way to go.

If you are a junior engineer, there should be someone watching over you. Ask them. (I'm surprised a window manufacturer even makes a window frame like this.) One of the basic rules of concrete is that you should never embed aluminum in concrete, especially if the concrete is exposed to the elements (i.e., water and freeze/thaw, carbonation, etc. The concrete will spall, water will get into the building, and everyone will get sued.

As everyone else said - bad idea.

honestly it just looks like a drafting error
cant imagine anything else
or an equally junior CAD draftsman just making things up
