Concrete fillable wall formwork assembly with interconnectable formwork elements

摘要

A formwork assembly is adapted to receive concrete to produce structures such as wall structures. The formwork includes PVC tubular form elements having recessed female engagement portions. The female engagement portions are adapted to receive respective male engagement portions. An octagonal form element has a female engagement portion positioned at each vertex between adjacent sides. A recessed female engagement portion is closed to the interior of the form element but open to the exterior of the form element. Thus, the form element includes a plurality of vertices open to the exterior. The form elements also include male engagement portions at an open side. Wall panels, corner panels, and joint connectors can also include male engagement portions. The male engagement portions and female engagement portions are adapted to mate to form a formwork arrangement having a substantially flat exterior wall. A formwork assembly can additionally include concrete flow apertures and insulation.

1. An apparatus comprising:
an elongated octagonal tubular form element,
wherein the tubular form element includes a tubular boundary,wherein the boundary bounds a longitudinal interior chamber,wherein the tubular form element includes at least one female engagement portion adapted to engagingly receive a male engagement portion,wherein the at least one female engagement portion extends into the interior chamber,wherein the tubular form element includes at least one male engagement portion extending outwardly of the boundary and an insert panel, wherein the panel has at least one substantially straight or flat surface,
wherein the panel has two ends and a male engagement portion at each end, andwherein each male engagement portion is adapted to engage a matching female engagement portion on the elongated tubular formwork form element whereby the engagement of the male engagement portions on the insert panel to matching female engagement portions forms a triangular closed area and whereby the engagement of the insert panel forms a substantially flat wall along elongated octagonal tubular form elements to which the insert panel is engaged.
