The present invention relates to a self-supporting, prefabricated, folding form structure or mechanism to be used in the construction industry. It is based on various types of geometries, providing enhanced strength and stability for the concrete and other building material casting process. The object of this invention is a foldable, prefabricated, self-supporting form and does not require a structure. It is configured in a variety of geometric shapes and is based on structural elements that have internal casting chambers or ducts interconnected between each other through perforated holes. This is done by means of internal assembly channels or cavities forming casting chambers. The casting chambers are interconnected with each other, through holes drilled in the structural elements. This way the form features an assembly between its walls through cracks or assembly cuts, creating an architecture of superior engineering that provides higher resistance and stability.

Disclosed herein is a concrete form apparatus that can be utilized to establish a rigid perimeter within which concrete can be poured for curing. A first component of the concrete form apparatus can be composed of a flat rigid material that is rectangular in shape and includes perforations along the lengthwise dimension of the material such that, when the material is folded along the perforations, an internal cavity is formed. The second component of the concrete form apparatus can be composed of a material having dimensions sized in accordance with the internal cavity of the folded material such that the first component can be folded along the perforations in the manner described above to encapsulate the second component within the internal cavity. Adhesive layers can be applied to prevent the concrete form apparatus from separating, and layers of the concrete form apparatus can be coated with a waterproofing substance.

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.

A light-weight formwork having a small change in dimensions due to an environmental temperature. A foundation formwork includes a metal frame having a rectangular frame shape, and a resin faceplate attached to the metal frame and closing an opening of the metal frame. The metal frame includes a top plate having fitting notches and L-shaped bridged bodies. The resin faceplate includes protruding bodies fitted with the fitting notches and L-shaped slits into which the bridged bodies are fittingly inserted. The protruding bodies fit with the fitting notches and the bridged bodies are fittingly inserted into the slits, thereby the resin faceplate is attached to the metal frame. The attached resin faceplate closes an opening of the metal frame. The fitting notches and the bridged bodies suppress an expansion and contraction of the resin faceplate in a left and right direction.

A supporting structure of plastic construction for a formwork panel, comprising a supporting structure and a formwork skin which is positioned on the front side of the supporting structure and attached to the supporting structure, wherein the supporting structure has two longitudinal edge supports and two transverse edge supports,

characterized in that the supporting structure comprises a main body made of plastic, to which the two longitudinal edge supports and the two transverse edge supports belong, and, in the region of the front sides of the two longitudinal edge supports and/or of the two transverse edge supports, has an edge protection provided for protecting at least part of the edge of the formwork skin after attachment thereof to the supporting structure, wherein the edge protection is made of a material different from the material of said supports of the supporting structure and has a portion projecting forward from the respective said support; and/or

in that the supporting structure has a main body made of plastic, to which the two longitudinal edge supports and the two transverse edge supports belong, and, in the region of the front sides of the two longitudinal edge supports and/or of the two transverse edge supports, and/or in the region of the rear sides of the two longitudinal edge supports and/or of the two transverse edge supports, has a reinforcement made of a material different from the material of said supports of the supporting structure.
