ABSTRACT:
A foundation pier for supporting a movable dwelling, such as a mobile home or commercial coach is provided. The pier provides enhanced seismic and wind force absorption properties over prior art piers. The invented pier includes a base plate having a threaded shaft affixed thereto. A plurality of webs are spatially positioned about the shaft at predetermined intervals. A support member has a first end threadably coupled to the shaft for adjusting the height of the pier. Couple members detachably couple to second end of the support member for attaching the pier to a support beam of the movable dwelling to prevent movement between the pier and the dwelling. A clamp member is affixed to the plurality of webs. The clamp member couples to the support member for preventing movement of the support member relative to the shaft and the clamp member. Environmental forces applied to the support member are transmitted from the clamp member and distributed through the plurality of webs to prevent the pier from collapsing.
