ABSTRACT:
A concrete lintel form includes a pair of elongate side members for installation in opposing face-to-face relation spanning a structure opening, such as a window or door opening, for fabrication of concrete beams or composite concrete masonry beams. Each form member comprises a generally vertical sidewall having inwardly projecting top and bottom legs running the substantially the entire length of the member. The top legs function to support masonry block stacked on top of the form to allow for the construction of a composite cast in place beam. The bottom legs function to support a bottom form that may be inserted after masonry has been stacked and secured with mortar, thereby allowing the workers to leave an opening that allows mortar droppings to fall through and not collect in the form. Each form member includes at least one outwardly projecting stiffener running substantially the entire length of the member between the top and bottom. The stiffener functions to resist outward expansion of the form as concrete is placed therein thereby minimizing bracing requirements.
