A drilling platform constructed from columns of box support members. Each column has one or more spreader support brackets extending toward another spreader support bracket on an opposite column. Outwardly flaring locking arms rise from the spreader support brackets. A locking aperture is contained in the flared portion of each locking arm. The mouth of the aperture is preferably at about a thirty degree angle to its base so that the mouth is generally facing up. Spreader beams connect the columns. Each spreader beam has a locking pin at each end. The spreader beams are lowered onto the support arms of each column. As they are lowered, the locking pins are aligned to engage the locking apertures and thereby secure the spreader beams to the columns. Once the spreader beams are in place, a work platform can be built on top of the columns and spreader beams.
