In a formwork system frames are mounted between horizontal supports. The
support means on
the frames are offset relative to the horizontal axis so that the inversion of
the frames enables
the level of the upper surface thereof to be adjusted. Thus the same
components can be used
to make a formwork for fine finish concrete or standard finish. In an
alternative embodiment the
support means on the horizontal support is offset so that the adjustment can
be effected by
reversing the support.

A multi-story concrete building is constructed concurrently, that is, the
steps for constructing the
same are carried out simultaneously on different respective stories. To
achieve this end, vertical
formwork members for forming the columns and bearing walls for one story are
erected. Then
decking formwork is erected for forming a concrete slab to serve as the floor
for the next story
thereabove. Formwork spacers are affixed to the tops of the vertical formwork
members and
these spacers provide mounts, extending through the thickness of the slab to
be formed, for
mounting the vertical formwork members for the next story. The vertical
formwork members for
the next story are then erected. Fresh concrete is poured into at least the
vertical fromwork
members and is permitted to cure and solidify into the vertical support
members for that story.
Other formwork members are erected above the next story while concrete is
concurrently
poured and formwork is stripped on different respective stories. The form
spacers can, e.g., be
channel members or, alternatively, closed-end angle members.

An internally threaded insert anchor for use in poured concrete floors having
metal decking or
wood form is described which provides setal deck or wood form, prior to the
concrete being
poured. Once locked into the concrete floor, the threaded insert anchor
provides easy
attachment for the support rods that carry the racks of utility, piping and
ceiling grid systems for
the building. Each threaded insert anchor is capable of accepting two
different size rods or bolts
with different thread cuts. The internal threaded apertures are protected from
concrete intrusion
during the pour by the plastic or metal sleeve. Moreover, the anchors are
designed so that
subsequent spraying of the ceiling with fire retardant or insulation foam will
not penetrate into
the threaded apertures, so as to prevent subsequent entry of the support rods.
While these concrete forms may be suitable for the purposes for which they
were designed,
they would not be as suitable for the purposes of the present invention, as
hereinafter
described.

SUMMARY OF THE PRESENT INVENTION
A primary object of the present invention is to provide a concrete forming
device that can be
easily assembled and disassembled utilizing interconnected pipe columns and
that are vertically
connected end-to-end via specially customized couplings in conjunction with
shims or collars.
Another object of the present invention is to provide a concrete forming
device that allows for
the entire layout of a multi-story buildings ceiling and floor forms to be
constructed at once and
allowing concrete to be poured from the ceiling down in one continuous pour if
desired.

Yet another object of the present invention is to provide concrete forming
device having pipe
columns that are interconnected by utilizing an intermediate base coupling
with mating threaded
members.
Still yet another object of the present invention is to provide a concrete
forming device that
utilizes collars or shims with and associated base coupling to aid in removing
base couplings
during disassembly of the device after poured concrete has dried.
Another object of the present invention is to provide a concrete forming
device having form
slabs with supporting brackets for producing a continuous planer surface for
forming ceilings
and floors out of concrete in a single pour from the top.
Additional objects of the present invention will appear as the description
proceeds.
The present invention comprises a pipe column having a threaded cavity on one
end and a
smooth bore cavity on the other with brackets positioned approximate its top
portion for
supporting form slabs horizontally. Also provided is a coupling for mating one
pipe column to
another with the coupling comprising a short length of pipe column having male
portions on
opposing ends with one having threads while the other is smooth and pin-like
with each
mateable to a respective pipe column cavity.
Also provided are spacers comprising a multi-part collar or shims positionable
between the
coupling threaded end and pipe column threaded end providing means for easily
disassembling
the formwork after use by removing the collar or shims enabling the coupling
to be threaded
9
CA 02803395 2013-01-22
further into the pipe column until the coupling pin end is free of its seated
positioned within the
pipe column.
To expand floors desired to an "x" and "z" surface area, columns are raised in
a side by side
manner so that they align adjacent to the sides of the upheld form slabs.
Additionally the present invention provides a builder the ability to erect a
buildings floor and
ceiling forms quickly and all at once so that pouring of concrete can start
from the top if desired
as a single continuous pour.
The present invention overcomes the shortcomings of the prior art by providing
a means for
creating entire concrete forms for constructing the ceiling and floors of
multistory buildings
utilizing a plurality of pipe columns and supported form slabs that are
erected to a desired height
and in horizontal alignment. Additionally the present invention provides for
the ability to pour
concrete in one continuous pour from the top and easy disassembly and removal
of the device
after said poured concrete has dried.
The foregoing and other objects and advantages will appear from the
description to follow. In
the description reference is made to the accompanying drawing, which forms a
part hereof, and
in which is shown by way of illustration specific embodiments in which the
invention may be
practiced. These embodiments will be described in sufficient detail to enable

embodiments may be utilized
and that structural changes may be made without departing from the scope of
the invention. In
the accompanying drawing, like reference characters designate the same or

throughout the several views.
The following detailed description is, therefore, not to be taken in a
limiting sense, and the
