Support band? (5)

I believe the answer is:

truss

I believe this is a double definition.

'support' is the first definition.
(trussing is a kind of supporting)

'band?' is the second definition.
(thesaurus)

(Other definitions for truss that I've seen before include "Medical support" , "Bind like a chicken" , "Padded device worn to support a hernia" , "Wing beam of a plane" , "Tie up tightly; frame" .)

I've seen this clue in The Times.
