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.

A prop head assembly is configured to be fixedly connected to a vertically-extending construction column, and also configured to support a horizontal construction beam assembly once the prop head assembly is fixedly connected to the vertically-extending construction column. The prop head assembly includes a first beam-locating feature and a second beam-locating feature. The first beam-locating feature is configured to selectively receive, at least in part, a beam-reference portion. The second beam-locating feature is also configured to receive the beam-reference portion once the beam-reference portion is inadvertently displaced away from the first beam-locating feature and from the vertically-extending construction column and toward the second beam-locating feature.

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.

The insulating concrete form system includes longitudinal and corner block assemblies each having a pair of side panels configured with tie receivers interacting with panel spacing ties to hold the side panels in an opposing manner and leading edges with an alternating arrangement of projections and recesses for interlocking with neighboring block assemblies. Each panel spacing tie includes a mid-support section interposing in between and connecting to a pair of end sections by a living hinge with each end section being configured with a flange member for placement within an opposing spatial wedge of the tie receiver, whereby the living hinge possesses the capability of allowing the side panels to move inwardly toward one another in a racked position to yield compactness of the longitudinal block assembly for economical transport. The corner block assembly also includes corner panel spacing ties to supplementally reinforce its structure to withstand hydrostatic blowout caused by poured concrete.

A connector assembly (400) for connecting a pair of formwork panels (200) with each other is disclosed. The connector assembly (400) includes a base component (402) having an arm, a first opening (602) formed on the arm, and a locking portion (406) formed at an end of the arm and adapted to be removably inserted in a second opening formed by alignment of respective slots (204) of the pair of formwork panels (200). The connector assembly (400) further includes a handle component (404) adapted to be partially disposed in the base component (402) through the first opening (602) formed on the arm. The handle component (404) is adapted to be operated to rotate the arm such that the locking portion (406) is rotated within the first opening (602) to partially lock the base component (402) in the first opening (602) for connecting the pair of formwork panels (200).
