4 DEFINITIONS
4.1 Fixture Support (Carrier) 一 GeneralDescription
As covered in this Standard, a fxture support (carrier)is a device that is anchored to the floor and concealedin the building construction (i.e., pipe chase), designedto support off-the-floor plumbing fixtures (any sanitaryplumbing fixture,located adjacent to the wall，whichhas no visible contact with the floor in front of thewall) independent of the wall or partition. In additioncombination carriers for off-the-floor water closets in-clude waste fittings to convey fixture discharge to thesanitary drainage system.
4.2 Fixture Support (Carrier) – SpecificComponents
alignmenf truss: the structural member of a carrierdesigned to maintain proper spacing of other carriercomponents，usually the uprights. Sometimes calledtie rod”
anchor studs. the studs attached to the bearing platefor bottom anchoring of some types of fixtures.
bearing plate: a plate attached to the uprights withprovisions for bearing or anchor studs.
bearing studs: the studs attached to the bearing plateto hold the fixture off the wall.
concealed arm. the fixture support member that extends horizontally from the upper end of a lavatorycarrier upright and is concealed in the fixture
coupling: the component that compresses the fixturegasket and provides the conduit for waste between thefixture and carrier faceplate. Sometimes called “extension.
exposed arm: the fixture support member that extendshorizontally from the upper end of a lavatory (or sink)carrier upright, on which the fixture rests, and is fullyor partially exposed to view.
