US 2019/0376301 A1 · CONCRETE FORMING SYSTEM

Abstract

A self-climbing concrete wall form hoist for forming a concrete wall section atop a previously formed wall section has a wall mounting releasably secured to the previously formed wall section, a plurality of moveable vertical masts, an extendable cylinder inside each mast, and a platform alternatively supported on the masts, which in turn are supported alternatively on the upper and lower wall mountings. The apparatus cycles between a platform raising position when the masts and platform are supported on the upper wall mounting and a lower wall mounting raising position when the masts and platform are supported on the upper wall mounting. The extendable cylinders are extended to raise the mast and platform relative to the lower wall mounting when the masts are supported on the upper wall mounting, and the extendable cylinders are retracted when raising the lower wall mounting relative to the platform when the masts and platform are supported on the upper wall mounting. The self-climbing concrete wall form hoist can descend a wall by effectively reversing the steps required to complete wall climbing.

A self-climbing concrete wall form hoist for forming a concrete wall section atop a previously formed wall section, the hoist comprising:

(a) upper and lower wall mountings releasably securable to the previously formed wall section;
(b) at least one moveable vertical mast;
(c) an extendable cylinder moveably coupled with the at least one mast, the cylinder comprising:
(i) a retracted position wherein the cylinder is disposed within the at least one mast;
and
(ii) an extended position wherein the cylinder is extended from the at least one mast;
and
(d) a platform alternatively supported on the upper and lower wall mountings,
wherein the form hoist is cycleable between:
(i) a platform raising position wherein the extendable cylinder is supported on the lower wall mounting, wherein the extendable cylinder is extendable into the extended position, whereby the platform is raised in relation to the concrete wall section;

A self-climbing concrete wall form hoist comprising:

(a) at least two extendable masts, each of the at least two masts comprising:
(i) a mast body comprising an interior cavity;
(ii) an extendable cylinder moveably coupled to the mast body;
(iii) a retracted position wherein the extendable cylinder is disposed within the interior cavity;
and
(iv) an extended position wherein the extendable cylinder is extended a predetermined length out of the mast body;
(b) a lower removable attachment mechanism releasably attachable to a previously formed concrete wall section, wherein the lower removable attachment mechanism is fixedly coupled to the extendable cylinder;
(c) an upper removable attachment mechanism releasably attachable to the previously formed concrete wall section, wherein the upper removable attachment mechanism is fixedly coupled to the mast body;
(d) a platform moveably attached to the at least one extendable mast, wherein the platform is disposed above the lower and upper removable attachment mechanisms;
(e) a platform raising position, wherein the lower removable attachment mechanism is attached to the previously formed concrete wall section, wherein the at least one extendable mast is extendable into the extended position such that the platform is raised in relation to the concrete wall section;
(f) a lower removable attachment mechanism raising position, wherein the upper removable attachment mechanism is attached to the previously formed concrete wall section, wherein the extendable cylinder is retractable into the retracted position such that the lower removable attachment mechanism is raised in relation to the platform;
and
(g) a controller operably coupled to the at least two extendable masts, wherein the controller is configured to synchronize and control operation of the at least two extendable masts such that the controller causes the extendable cylinder of each of the at least two extendable masts to accelerate or decelerate to maintain a level alignment of the platform throughout movement between the extended and retracted positions.
