Abstract
An apparatus for building stem wall forms which can be easily deployed by a form laborer to set up stem wall forms at a building site. The apparatus is collapsible for easy deployment and removal from a stem wall form. The preferred embodiment is comprised of a collapsible rectangular center structure coupled to a board holder and a board support arranged in diagonal relation to each other. The board holder allows the apparatus to hang from a first form board and the board support allows a second form board to rest thereon. In use, the apparatus functions by holding opposing form boards of a stem wall form in a parallel relation to each other, so that the form boards can be staked and nailed into place. Once the form boards are staked in place, to create a stem wall form, the apparatus can be collapsed, and removed from the form to be reused again at another location.
