Cutting opening in concrete joist floor system - Structural ...
I have a project where a small hole or two maybe 24"x24" need to be cut in a concrete slab. This is a one way concrete joist floor pan joists from the 920& 39;s. I know these types of slabs are usually quite thin maybe 2.5" and minimally reinforced with 3 bars because the spans are so short usually only a couple of feet between joists .【Get Price】

How to Cut Concrete with a Concrete Saw – The Family Handyman
The downside to dry-cutting masonry is the tornado of fine dust it creates. If you cut concrete indoors seal off the area with plastic and duct tape. Seal all duct openings as well. Wet-cutting diamond blades can have either teeth or a smooth continuous perimeter. Water not only helps cool and lubri e the blade but also keeps the dust down.【Get Price】
STRUCTURE magazine Creating an Opening in Existing Floors
A one-way slab is considered when an aspect ratio of at least two is realized. A one-way slab will function like a beam in the short direction continuously spanning over supports such as T-beams or walls. However continuity will be interrupted at the proposed opening and the slab’s required design moments at adjacent spans will be increased.【Get Price】
