The disclosure presents a composite conduit formwork structure which includes a cylindrical outer casing adapted to bond with a cylindrical inner casing which are maintained at a fixed distance apart by a plurality of radial stanchions. The inner casing and outer casing form an interior void which is filled with concrete during manufacture. The outer casing and inner casing remain in place to protect the structure once completed. A novel method of assembly is also provided whereby radial stanchions are rotated between the outer casing and inner casing. All of the components in a preferred embodiment are formed of a fiberglass material.

Apparatuses and methods associated with creating a form to construct a concrete structure (e.g., a concrete building). In embodiments, an apparatus may comprise a number of forming system components, including but are not limited to a plurality of fixed or adjustable posts; a plurality of fixed or adjustable roof struts, a plurality of fixed or extensible frames; and/or a plurality of mounts. The fixed/adjustable posts, the fixed/adjustable roof struts, and the fixed/extensible frames are selectively and adjustably coupled together to create a form of selected dimensions to construct the concrete structure/building on site with reduced number of pours, e.g., a single pour. Other embodiments may be disclosed or claimed.

This invention relates to modular building construction apparatus and in particular to a mold having movable framework used to construct a basic building module where any miss-alignment at the junction of framework elements is enough to make the imperfection noticeable. If the imperfection is a ridge it will be readily apparent on the inside surface of the formed building module and it will not be disguised by painting over it. What is disclosed is a movable corner arrangement for a mold for forming at least one of the inner corner surfaces of a moldable building module. The inner mold for a moldable building module has an upper support panel for forming the ceiling surface of the building module and a plurality of movable side walls that depend from the upper support panel using flexible peripheral edge elements. The side walls have mold facing side wall surfaces movable to a position to form corresponding internal wall surfaces of the moldable building module. The movable side walls are movable inwards and away from their respective formed internal wall surfaces to release the formed building module from the inner mold. A movable corner arrangement is used to form the internal corners of the moldable building module located between adjacent movable side walls. The movable corner arrangement includes a corner post having at least one side wall abutment surface; a corner post support coupling adapted to adjust the vertical and sideways position of, and verticality of the corner post with respect to the desired position of adjacent movable side walls such that the mold facing surface of the corner post is flush with the mold facing surface of respective adjacent movable side walls during the molding process.

A concrete forming system combining the ease of erection and load carrying capabilities of scaffolding with a simplified erection system. Scaffold frames provide the vertical support and walers, supported by and spanning from scaffold frame to scaffold frame, provide the horizontal support. The wet concrete's hydrostatic pressure is placed on the walers, which transfer the load to the scaffold frames that act like trusses. The scaffold frames have at least two legs and are secured at their bottom to perform as a cantilever or, when the hydrostatic pressure is greater, they are secured at their bottoms and tops to perform as a truss fixed at both ends. As such, this forming system does not use form ties which results in an obstacle free form face and facilitates forms that simply hang from the walers.
