ABSTRACT:
An elevated column base for supporting a wood column subjected to high mechanical loads and protecting the column lowermost portion from rot and other deterioration due to exposure to a tropical environment. The column base includes a stanchion, a diaphragm, and a cap, each monolithically molded from a thermoplastic. A first embodiment of the stanchion adapted for a 6.times.6 or 8.times.8 column includes a solid base portion with a cavity which is filled with concrete and plugged with the diaphragm. The stanchion has two pairs of side walls attached to the base portion. Opposed gussets attached to the upper portions of one pair stiffen the side walls against transverse loads. Most of the load carried by the wood column is borne by the concrete and by two horizontal bolts. The diaphragm acts to spread the load force to the base portion and side walls. The load on the diaphragm acts to create a seal against moisture entering the cavity. A second embodiment of the stanchion adapted for a 4.times.4 column does not include gussets. The cap has four lateral faces fitting closely over the stanchion side walls, and a top face with a square aperture formed by four flexible web portions pressing against the wood column. After the column lowermost portion is secured within the stanchion by the bolts, the cap is slid downwardly until the ends of slots in the lateral faces contact the bolts. Each cap bottom corner edge and trough then bound an aperture through which water collected above the diaphragm can drain.
