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

L'invention concerne un ensemble coffrage pouvant recevoir du béton en vue de la fabrication de structures telles que des structures murales. Ce coffrage comprend des éléments de coffrage tubulaires en PVC comportant des parties de prise femelles évidées. Ces parties de prise femelles sont conçues pour recevoir des parties de prise mâles respectives. Un élément de coffrage octogonal comporte une partie de prise femelle située au niveau de chaque sommet entre des côtés adjacents. Une partie de prise femelle évidée est fermée sur l'intérieur de l'élément de coffrage mais ouverte sur l'extérieur de l'élément de coffrage. Ainsi, l'élément de coffrage comprend une pluralité de sommets ouverts sur l'extérieur. Ces éléments de coffrage comprennent également des parties de prise mâles au niveau d'un côté ouvert. Des panneaux muraux, des panneaux de coins et des raccords de jonction peuvent également comprendre des parties de prise mâles. Les parties de prise mâles et les parties de prise femelles sont conçues pour s'accoupler de manière à former un ensemble coffrage présentant une paroi extérieure sensiblement plate. Un ensemble coffrage peut en outre comprendre des ouvertures d'écoulement de béton et des éléments d'isolation.
