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 opening in the pallet. A readily removable key bolt type clamp extends through each of the aligned openings for rigidly clamping the forms to the pallet. Each such clamp comprises a bolt with a slot in its shank and a wedge which is receivable in the slot for rigidly clamping the foundation part to the pallet. Washers are provided between the wedges and and the stiffener angle pieces. Between each pallet section a connecting strip is provided having openings which match openings in the underlying pallet sections. Key bolts, as described, are utilized to clamp the strips to the sections and thus the sections are rigidly interconnected in their desired level position.
