The invention comprises a concrete form. The form comprises a first concrete forming panel having a first primary surface adapted for forming and contacting plastic concrete and a second primary surface opposite the first primary surface; a layer of insulating material contacting and substantially covering the second primary surface of the first concrete forming panel; and an insulating blanket adjacent the first concrete forming panel. A method of using the concrete form is also disclosed.

A method and an article of manufacture are disclosed for constructing, reinforcing, and repairing various structural elements such as columns, piles and the like using formworks that are reusable. The reusable articles of manufacture employed in the disclosed methods are or, if desired, may be permanently left in place. Same or similar methods and articles of manufacture may be employed to easily construct pipes of any desired diameter in a very short time.

A form for curable construction materials, comprising an elongated, substantially planar wall having a selected thickness, the wall having inner and outer surfaces, a flange region extending from the wall, the flange region having a flange substantially running the length of the wall, wherein a bore substantially running the length of the wall is formed adjacent the wall and the flange, the flange region further having first and second angled surfaces extending therefrom, wherein a channel extending to the bore is formed between the first and second angled surfaces, wherein one form may be assembled with other forms using pins inserted into respective bores to create a containment system for construction materials.

A collar assembly of or for a tower being formed by progressively higher concrete composition pours into reinforcement including formwork defined cavities, the assembly comprising or including; a higher subassembly adapted as a collar to selectively index to a zone of the tower being formed, a lower subassembly adapted as a collar to selectively index to a zone of the tower being formed, and a jacking arrangement whereby (I), when the lower subassembly is zone indexed and the higher subassembly is not, the higher subassembly can be raised relative to the lower subassembly and the zone to a fresh indexing height and (II), when the higher subassembly is zone indexed and the lower subassembly is not, the lower subassembly can be raised to a fresh indexing height.

Various implementations described herein are directed to a formwork system. In one implementation, the formwork system includes aluminum extrusions and aluminum castings. The aluminum castings and the aluminum extrusions can be assembled by being pressed and riveted together.

An apparatus for forming a concrete column is disclosed. The apparatus may include a first column form half and a second column form half, which may be designed to be fitted together. The apparatus may also include a fastening system having at least one brace and a plurality of straps to fasten the first column form half with the second column form half to form a full column form. The full column form may then be filled with a poured concrete mixture, which when hardened or cured, may be a concrete column used in any number of structural or design applications.

A tray-like modular building component adapted for filling with concrete after assembly with like components into a building frame, said tray-like modular building component comprising: a substantially rectangular frame with a pair of opposed sides and a pair of opposed ends defining an interior therebetween; a sheet mounted to said building frame and extending over said interior; a pair of beams, each mounted to said building frame along each said pair of sides respectively; and a pair of end plates, each mounted to said building frame along each said pair of ends respectively, wherein said sheet, said pair of beams and said pair of end plates together form an open-topped tray for receiving the concrete therein.
