Abstract: A dual ratchet pawl jacking system, device, and method are presented for raising and/or lowering a platform bearing carriage along a vertical support. The ratchet pawls alternate supporting the weight of the carriage by engaging against a series of lugs on the vertical support. A first pawl is attached to the main frame of the carriage, and a second pawl is attached to a sub-carriage assembly that slides upward and downward within the carriage frame. A hydraulic jack applies a force upon the sub-carriage, causing the sub-carriage to move within the frame. The weight of the carriage is alternately borne by each pawl as the other pawl is relocated to a new lug. A pair of triggers is used to retract the first pawl and second pawl from the support. The triggers may be enabled to facilitate lowering the carriage, or disabled to facilitate raising the carriage.

Abstract: A casting tool for forming precast concrete wall sections. A base is disposed generally in a horizontal plane and has an upper surface. A pair of opposing sidewalls are disposed proximate the upper surface. Each of the sidewalls has a first position in which the sidewall is located substantially in a vertical plane. First and second opposing bulkheads are disposed proximate the upper surface, each having a respective first position in which the bulkhead is located substantially in a vertical plane. The bulkheads are arranged to abut the pair of opposing sidewalls so that the inner surfaces of the sidewalls, the bulkheads, and the upper surface of the base define a form for receiving concrete to make the precast concrete wall section. The first bulkhead is configured for movement so as to vary a first dimension of the form, and thus the dimension of the concrete wall section.

Abstract: A concrete form has a pair of opposed upstanding and spaced apart side panels. A space is defined between the side panels. Each side panel has a respective upper edge and a respective lower edge whereby a top opening is defined between the upper edges and a bottom opening is defined between the lower edges. At least one bottom soffit panel is coupled to the form and is movable between a first soffit position closing off the bottom opening and a second soffit position providing access to the space through the bottom opening. At least one transverse top beam is coupled to the form and is movable between a first top beam position across the top opening and a second top beam position providing access to the space through the top opening. A method of setting up the concrete form includes assembling the form, opening the top beam if closed, installing at least one steel reinforcing element within the forming space through the top opening, and closing and securing the top beam.

Abstract: 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.
