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.

Dependent claims

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.
