ABSTRACT:
A method for casting multiple floor beams including the steps of assembling a multiplicity of spaced pan form units where the space between adjacent pan units forms the side of a beam form. A bottom panel is positioned between adjacent pan units to form the bottom of the beam form. The pan units are then locked together on their underneath sides to form an integral pan deck. Reinforcing framework is added into the beam forms and the pan form units are then locked together on their top sides. Concrete is then cast into the beam forms to form beams of a first floor level after which the underneath sides of the pan form units are unlocked and the bottom panel removed. The integral pan unit is then raised by jack means to a second floor level. During the time that the integral pan deck is being raised or after it is raised, the bottom panel is repositioned and the panels are again locked together on their underneath sides. The assembly is then in position in which the steps may be repeated.
A form for multiple floor concrete construction which includes a plurality of spaced pan units where the units have sloping sides to form the sides of a beam form having negative draft. Removable bottom panels are provided to form the bottom of a pan unit. Locking means are provided on the top and underneath sides of the pan units by which the pan units may be locked together to form an integral pan deck. Jacking means are included to raise the integral pan deck from a first floor position to a second floor position.
