Abstract
Mold apparatus for the manufacture and molding of structural members such as I-beams and concrete girders which has a permanent pallet supported and maintained in a level condition by parallel beams affixed to a concrete base. The pallet is made up of a plurality of sections mounted on the beams and aligned and rigidly connected together. A pair of side forms are provided on the pallet which are readily removable and replaceable by other forms depending upon the particular structure being molded, each such form having a horizontal foundation part which extends to the edge of the pallet where a strip is welded to position the mold as desired on the pallet. The inner portion of the foundation part merges with a molding part extending upwardly in each form and terminating in an upper flange extending horizontally and outwardly at the top of the form. A plurality of vertical stiffener plates connect the various parts of each form to provide rigidity. Also a stiffener angle piece is affixed to each form along the juncture of the foundation and molding parts. A plurality of openings are provided in the foundation part through the stiffener angle piece which are aligned with a further ope…
