shoring jack distances supporting slab

shoring jack distances supporting slab

(OP)
I just wanna ask if there is a minimum or maximum distance of shoring jacks supporting the slab after the formworks has been removed?

RE: shoring jack distances supporting slab

You seem to be asking for a specific answer to a very general question. You'll probably need to give more detail of the slab thickness, time from pouring to form removal, etc. to get meaningful answers.

RE: shoring jack distances supporting slab

The shoring jack mfg. should have specifications on their product. For preliminary design or spacing requirements, then ofcourse you would consider other issues such as soil bearing capacity or condition of supporting soils, any other specific site load requirements.

RE: shoring jack distances supporting slab

There could have a rule of thumb by shoring contractors I'm not aware of, but as an engineer, you need to ensure the re-shore shall be setup in a manner that will prevent the slab to experience internal stresses due to construction activities prior to attain the specified compressive strength. Be conservative in estimating and designing such system.
