Abstract A support member for use in a support system wherein the support member is positioned under a beam of a structure is shown. The support member includes a planar base and a bottom member operatively coupled to the planar base. The bottom member has a vertically extending portion defining a thrust bearing member receiving cavity. A raised locking boss is attached to the planar base and is positioned adjacent the vertically extending portion within the thrust bearing member receiving cavity. A support member which has a planar support plate is passed through the vertically extending portion of the bottom member into mating position with the raised locking boss to lock the same in position and to prohibit rotation thereof about an axis passing perpendicular to the plane of the planar support plate. The support member includes a vertically extending support shaft which is affixed to the planar support plate and includes first coacting surface located around the periphery thereof. A thrust bearing member has a collar and outer lip having an opening extending axially therethrough with the interior thereof formed with a second coacting surface which is capable of coacting with the first coacting surface. An elongated sleeve member, which supports a top member, is in affixed to the collar. The thrust bearing member is brought into contact with the vertically extending support shaft such that said first coacting surface and the second coacting surface coact with each other and are responsive to a rotational force applied therebetween to vary the distance between the planar support plate and the thrust bearing member.
A support member for use in a support system for a building structure having a foundation formed of a plurality of spaced, parallel support beams wherein the support member is adapted to be positioned under one of said beams, the support member comprising: a planar base having a preselected cross-sectional area; a bottom member fixed to the planar base, the bottom member having an upwardly extending hollow cylindrical portion of a predetermined inside diameter and having an open top end; a top member including a stabilizing plate and having a cylindrical extended lower portion of a second predetermined inside diameter, said top member including gripping means adapted to be fixedly attached to said stabilizing plate and to one of said beams; an intermediate member interposed between the base and the top member, the intermediate member having a cylindrical top portion sized for nesting engagement within the lower extended portion of the top member and having a cylindrical bottom portion sized for nesting engagement within the upwardly extended portion of the bottom member, the intermediate member comprising two elongate members, threadably interconnected so that rotational movement of the elongate members relative to each other adjusts the overall length of the intermediate member, thereby allowing adjustment of the intermediate member independently of the bottom member.
