May one plug a window on Shabbat with a board or similar object that is not tied, if one had it in mind from erev Shabbat?

ShabbatBuilding (Boneh)

Synopsis

The Mechaber rules that a window plug (pakak ha-chalon) may be used to close a window even if not tied, provided one had it in mind from erev Shabbat, since this is considered adding to an existing ohel arai rather than building. The Biur Halacha notes a dispute whether mere intention suffices or whether the plug must have the status of a kli.
