An adjustable truss for reinforcing a floor supported atop horizontal joists has a beam which underlies the floor and includes reinforcing members having spaced apart limbs which provide space for the accommodation of utility components such as wiring, pipes, and conduits. The support members are removable from the beam so as to enable any selected support to be uncoupled from the beam and recoupled thereto following movement of the support member in such manner as to enable the utility components to be accommodated in the space between the limbs. The support members are rockable in either of two opposite direction so as to enable the beam to be adjusted in such manner as to maintain bearing engagement with the underside of the floor.
