Abstract
Abstract Apparatus for modular concrete constructions. The apparatus comprises a carriage and a concrete form. It also comprises the combination of a concrete form detachably mounted on a portable carriage the former of which can be set in place and positioned for pouring. The carriage can then be detached from the concrete form, removed for further service and later reunited with the form for transport to a new pour position, as desired. The concrete form per se is comprised generally of a support structure atop which is provided a pour form. The pour form is constituted of a central span and, preferably, a pair of upwardly faced troughs located on opposite sides of the central span. The central span of the pour form can range from flat to highly contoured. The troughs are each provided with a plurality of bottom openings, these being formed between removable panels. In forming a module, wet concrete can be poured upon the central span of the pour form to form a roof, ceiling, or floor while a tubular member or column form can be fitted into the openings of the trough at the column locations and wet concrete can be poured therein and into the troughs to cast columns and beams for support of the roof, ceiling or floor. After the concrete has set the pour form can be lowered, the troughs freed by removal of the panels at the columns, and the beam forms moved inwardly. The carriage can then be removed to an adjacent location for further pouring.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
258 words
A concrete form for detachably mounting upon a transporting carriage comprising a frame assembly wherein is included a plurality of vertically oriented telescoping posts, and braces suitable for maintaining the vertical alignment of said posts, jacks located on the lower extremities of said vertical posts, which terminate on a common plane, said jacks permitting minor adjustment of the height of the vertical posts, means located on the lower extremity of said frame assembly for attachment to a means of transport, a concrete pour form, provided with a central span which ranges in shape from flat to highly contoured, mounted atop said telescoping posts, locking means whereby the telescoping posts can be raised, lowered and locked to support the concrete form at a desired elevation, beam forms, trough-like in shape and opening upwardly, mounted on the sides of said central span of said concrete pour form, carried by laterally oppositely disposed horizontally oriented telescoping tubular members mounted within the top portion of the frame assembly, a plurality of gear boxes mounted on the upper part of said frame assembly operatively geared one to another and to a rotatable shaft, gear means associated with said horizontally oriented telescoping tubular members which gear said members to said gear boxes and to said rotatable shaft such tHat rotation of said rotatable shaft in one direction will cause said telescoping tubular members to telescope outwardly and extend the beam forms, and rotation of said shaft in the other direction will cause said telescoping tubular members to telescope inwardly and retract the beam forms.
Claim 2
Dependent Claim
258 words
A concrete form for detachably mounting upon a transporting carriage comprising a frame assembly wherein is included a plurality of vertically oriented telescoping posts, and braces suitable for maintaining the vertical alignment of said posts, jacks located on the lower extremities of said vertical posts, which terminate on a common plane, said jacks permitting minor adjustment of the height of the vertical posts, means located on the lower extremity of said frame assembly for attachment to a means of transport, a concrete pour form, provided with a central span which ranges in shape from flat to highly contoured, mounted atop said telescoping posts, locking means whereby the telescoping posts can be raised, lowered and locked to support the concrete form at a desired elevation, beam forms, trough-like in shape and opening upwardly, mounted on the sides of said central span of said concrete pour form, carried by laterally oppositely disposed horizontally oriented telescoping tubular members mounted within the top portion of the frame assembly, a plurality of gear boxes mounted on the upper part of said frame assembly operatively geared one to another and to a rotatable shaft, gear means associated with said horizontally oriented telescoping tubular members which gear said members to said gear boxes and to said rotatable shaft such tHat rotation of said rotatable shaft in one direction will cause said telescoping tubular members to telescope outwardly and extend the beam forms, and rotation of said shaft in the other direction will cause said telescoping tubular members to telescope inwardly and retract the beam forms.
Claim 3
Dependent Claim
104 words
The apparatus of claim 1 wherein the gear means associated with said horizontally oriented telescoping tubular members comprise fixed nuts located within each of the outer members of the laterally oriented telescoping members and with shafts having threads of opposite cast located within each of the laterally oriented tubular members in association with the fixed nuts, and the rotatable shaft through the gear boxes are operatively connected together via appropriate linkage so that rotation of the shaft in one direction will cause the beam form to extend outwardly and rotation of the shaft in the other direction will cause the beam form to retract.
Claim 4
Dependent Claim
46 words
The apparatus of claim 1 wherein the locking means associated with the vertically oriented telescoping posts are comprised of a plurality of lateral openings within inner and outer telescoping posts through which pins can be passed upon alignment to lock the posts at the desired elevation.
Claim 5
Dependent Claim
180 words
The apparatus of claim 1 wherein the central span of the concrete pour form is constituted of a frame structure which carries parallel aligned horizontally oriented telescoping tubular posts, the terminal ends on each side of the pour form of which are U-shaped, faced upwardly and support trough-like members with a plurality of bottom openings formed by movable panels within which can be fitted tubular forms of various sizes and shapes, a plurality of the horizontal tubular telescoping posts inside each of which are axially mounted shafts having threads of opposite cast mounted within and in association with fixed nuts contained within adjacent pairs of telescoping posts, said horizontal tubular telescoping posts carrying gear boxes operatively associated, one with the other, by a common laterally disposed rotatable shaft, said common laterally disposed rotatable shaft being geared with each of said threaded shafts mounted within the horizontal telescoping members such that its rotation in one direction will cause the beam form to extend outwardly and rotation of the shaft in the other direction will cause the beam form to retract inwardly.
Claim 6
Dependent Claim
35 words
The apparatus of claim 4 wherein the bottom walls of the removable panels constituting the U-shaped pour form are provided with downwardly projecting wall segments which provide a collar for support of the tubular forms.
Claim 7
Dependent Claim
79 words
The apparatus of claim 1 wherein the beam forms are provided with bottom slotted removable panels which, when fitted together, leave bottom openings within which vertical concrete pour forms can be fitted such that wet concrete can be poured upon the central span of the concrete pour form to form a floor, ceiling or roof, into the beam forms to provide beams, and into vertical pour forms placed within the openings within the beam forms to provide supporting columns.
