May one reinsert a bench leg that has fallen off on Shabbat, or lean the side with the missing leg on another bench?

ShabbatBuilding (Boneh)

Synopsis

The Mechaber prohibits reinserting a dislodged bench leg. There is a stricter opinion that also prohibits leaning the damaged side on another bench. The Biur Halacha (citing the context of Siman 308) clarifies that normally-tight bench legs may not be inserted even loosely.
