Claim 3

The apparatus of claim 1 wherein the vertical posts of the concrete form are constituted of tubular members with a plurality of lateral opening there through which pins can be passed to lock the posts and consequently the pour form at the desired elevation.

Claim 4

Apparatus for modular concrete constructions comprising, in combination, a concrete form detachably mounted upon a carriage, the concrete form including a frame assembly comprising a plurality of vertically oriented telescoping posts, suitable braces for maintaining said alignment of the posts, a concrete pour form ranging in shape from flat to highly contoured mounted atop the said telescoping posts, laterally oriented telescoping members perpendicularly supported atop the vertically oriented telescoping posts, beam forms, in positions adjacent and one on each side of the said concrete pour form, supported upon the laterally oriented telescoping members, the said beam forms being provided with removable panels which form bottom openings within which can be fitted various sizes and shapes of column tubular forms, locking means whereby the telescoping posts can be raised, lowered and locked to support the concrete pour form at a desired elevation, means whereby the lower extremities of the posts can be detachably engaged with the carriage for transport and positioning of the said concrete form, and wherein the lower extremities of the vertical posts terminate on a common plane and the extremities are provided with jacks by means of which minor adjustments can be made to raise and lower the concrete form, the carriage including a frame, a set comprising at least three wheels provided with pneumatic tires upon which the carriage can be rested and transported, whereby the concrete form can be engaged with the carriage for transport, set in place by the carriage and the pour form positioned for pouring concrete, the carriage then removed after deflation of the tires, such that concrete can then be poured upon the said concrete pour form to provide a floor, ceiling or roof, into the beam forms to provide beams and into the tubular vertical forms to provide supporting columns, and the carriage can be later reunited with the concrete form after the concrete has set, for removal of the concrete form to a new pour position.

Claim 5

Apparatus for modular concrete constructions comprising, in combination, a concrete form detachably mounted upon a carriage, the concrete form including a frame assembly comprising a plurality of vertically oriented telescoping posts, suitable braces for maintaining said alignment of the posts, a concrete pour form ranging in shape from flat to highly contoured mounted atop the said telescoping posts, laterally oriented telescoping members perpendicularly supported atop the vertically oriented telescoping posts, beam forms, in positions adjacent and one on each side of the said concrete pour form, supported upon the laterally oriented telescoping members, the said beam forms being provided with removable panels which form bottom openings within which can be fitted various sizes and shapes of column tubular forms, locking means whereby the telescoping posts can be raised, lowered and locked to support the concrete pour form at a desired elevation, means whereby the lower extremities of the posts can be detachably engaged with the carriage for transport and positioning of the said concrete form, and wherein the lower extremities of the vertical posts terminate on a common plane and the extremities are provided with jacks by means of which minor adjustments can be made to raise and lower the concrete form, the carriage including a frame, a set comprising at least three wheels provided with pneumatic tires upon which the carriage can be rested and transported, whereby the concrete form can be engaged with the carriage for transport, set in place by the carriage and the pour form positioned for pouring concrete, the carriage then removed after deflation of the tires, such that concrete can then be poured upon the said concrete pour form to provide a floor, ceiling or roof, into the beam forms to provide beams and into the tubular vertical forms to provide supporting columns, and the carriage can be later reunited with the concrete form after the concrete has set, for removal of the concrete form to a new pour position.

Claim 6

The apparatus of claim 3 wherein the top portion of the frame assembly of the concrete form additionally carries a plurality of gear boxes adjoined one to another through a rotatable shaft, the oppositely disposed laterally oriented tubular members which carry the beam forms are each provided with nuts affixed therein and shafts, having threads of opposite cast, operatively associated with the fixed nuts, and the rotatable shaft through the gear boxes are operatively connected together via appropriate linkage with the shafts having threads of opposite cast so that rotation in one direction of the shaft connecting the gear boxes will cause the beam forms to extend outwardly and rotation of the shaft in the other direction will cause the beam forms to retract.

Claim 7

The apparatus of claim 1 wherein each of the wheels of the set is mounted on a spindle perpendicularly mounted on an end of an eccentric member, the eccentric member is pivotally mounted on a channel member forming the frame of the carriage via a bolt provided with lateral openings which is passed through an opening through the opposite end of the eccentric member, a slotted collar is permanently affixed about the end of the bolt on the side of the channel member opposite that whereon the eccentric is locaTed, the slots of the collar substantially corresponding with the location of the lateral openings through the bolt so that a pin passed through both the lateral openings and slots will secure and lock the eccentric, and consequently the spindle, at different position levels upon the frame whereby the carriage can be elevated and lowered by repositioning and locking the eccentrics at different levels with alternate inflation and deflation of the tires.

Claim 8

The apparatus of claim 5 wherein four slots are located at 90* angles, one relative to the other, and the lateral openings through the bolt are aligned therewith, so that the levels of elevation correspond to 90* increments about the circumference of the path of travel of the eccentric which is rotatable about the bolt.

Claim 9

The apparatus of claim 5 wherein the bolt is fitted within a bushing which is passed through the channel member forming the carriage frame, and the end of the bolt is threaded and held in place by a threaded nut.

Claim 10

The apparatus of claim 5 wherein air console means are provided for simultaneous rapid inflation and deflation of the pneumatic tires of a set of wheels.

Claim 11

The apparatus of claim 1 wherein outer corners of channel members forming the frame of the carriage are fitted with upwardly projecting lugs and the inside portions at the lower extremities of the vertical posts forming the frame assembly of the concrete form are provided with tubular segments, providing male and female members which secure the concrete form to the carriage and forms a ready breakaway feature for separation of the concrete form and carriage after the former has been positioned and set as desired.

Claim 12

The apparatus of claim 3 wherein a beam form is provided with oppositely disposed paired removable panels, of U-shaped cross-section, each of which is provided with shaped cut-away edges and downwardly projecting surrounding walls which, when fitted and secured together with fastening means, form an opening with an enclosing downwardly projecting collar within which a column tubular form can be fitted, the upper edges of which pair of removable panels are shaped as tubular sections which can be held in place upon a beam by passage of a bar therethrough.

Claim 13

The apparatus of claim 3 wherein a beam form is supported by a shoring member formed of telescoping tubular members, the height of which can be adjusted by locking means which support the said shoring member at the desired elevation.
