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 troughs 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 concerete 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: 9
Claim 1
Independent Claim
254 words
A concrete pour form support for use in pouring of vaulted type roofs which is mounted on a transportable type carriage for moving as a unit from one job site to another, which concrete form support can be detached from the carriage, removed for further service and later reunited with the carriage for removal to a new pour position, the combination comprising a horizontal frame assembly wherein is included a plurality of parallelly aligned, horizontally oriented beams, which lie in a common plane, a plurality of vertically oriented posts affixed upon each of the said beams, each post being extended downwardly for attachment to the carriage, a plurality of parallel sets of aligned tubular posts, the number of tubular posts in a set being substantially equal, the posts of each set radiating outwardly from substantially the center of the parallelly aligned, horizontally oriented beams constituting the horizontal frame assembly, a plurality of cross-bars corresponding in number with the number of tubular posts in a set which radiate outwardly from a beam located in the horizontal frame assembly, each cross-bar containing a plurality of downwardly projected, perpendicularly attached members which provide a telescoping fit with the tubular posts of the parallel sets of aligned tubular posts so that the said cross-bars can be adjusted inwardly or outwardly with regard to the aligned tubular posts to provide a surface which can be covered and rendered suitable for pouring thereon vaulted type concrete roof structures ranging in length of span and in contour from circular to elliptical.
Claim 2
Dependent Claim
254 words
A concrete pour form support for use in pouring of vaulted type roofs which is mounted on a transportable type carriage for moving as a unit from one job site to another, which concrete form support can be detached from the carriage, removed for further service and later reunited with the carriage for removal to a new pour position, the combination comprising a horizontal frame assembly wherein is included a plurality of parallelly aligned, horizontally oriented beams, which lie in a common plane, a plurality of vertically oriented posts affixed upon each of the said beams, each post being extended downwardly for attachment to the carriage, a plurality of parallel sets of aligned tubular posts, the number of tubular posts in a set being substantially equal, the posts of each set radiating outwardly from substantially the center of the parallelly aligned, horizontally oriented beams constituting the horizontal frame assembly, a plurality of cross-bars corresponding in number with the number of tubular posts in a set which radiate outwardly from a beam located in the horizontal frame assembly, each cross-bar containing a plurality of downwardly projected, perpendicularly attached members which provide a telescoping fit with the tubular posts of the parallel sets of aligned tubular posts so that the said cross-bars can be adjusted inwardly or outwardly with regard to the aligned tubular posts to provide a surface which can be covered and rendered suitable for pouring thereon vaulted type concrete roof structures ranging in length of span and in contour from circular to elliptical.
Claim 3
Dependent Claim
52 words
The apparatus of claim 1 wherein the aligned tubular posts affixed upon the horizontal frame assembly, and the downwardly projected, perpendicular members of the cross-bars are telescoping members, and locking means are provided whereby the individual cross-bars can be raised, lowered and locked to vary the contour of the concrete pour form.
Claim 4
Dependent Claim
45 words
The apparatus of claim 2 wherein the aligned tubular posts and the downwardly projected, perpendicular members of the cross-bars are each provided with a plurality of lateral openings through which pins can be passed to lock the concrete pour form support at the desired location.
Claim 5
Dependent Claim
46 words
The apparatus of claim 1 wherein the cross-bars which are mounted upon said parallel sets of aligned tubular posts are tubular, and contain a telescoping tubular member mounted thereon which can be adjusted inwardly or outwardly thereon to vary the width of the concrete pour form.
Claim 6
Dependent Claim
81 words
The apparatus of claim 1 wherein the horizontal frame assembly of the concrete pour form support includes three of the horizontally oriented beams, secured one to another by suitable braces, at the center of each beam is provided a bank of eleven aligned tubular posts located in a common plane and separated from one another by a 15° angle, and there is provided eleven cross-bars one for extension across three parallelly aligned members of the parallel sets of aligned tubular posts.
Claim 7
Dependent Claim
47 words
The apparatus of claim 5 wherein each of the cross-bars is tubular, and tubular beams are carried by each of the cross-bars and telescoped therewith such that said tubular beams can be adjusted inwardly or outwardly thereon to vary the width of the concrete pour form support.
Claim 8
Dependent Claim
41 words
The apparatus of claim 5 wherein the three horizontally oriented beams which form the horizontal frame assembly each carry a plurality of vertically oriented posts of tubular design, each extended vertically downwardly for attachment to tubular posts located on the carriage.
Claim 9
Dependent Claim
22 words
The apparatus of claim 5 wherein each of the aligned tubular posts are joined together at the specified angle by suitable braces.
