Abstract
The invention is a formwork system and a method of using the formwork to construct rammed earth walls. The formwork comprises end panels which can be quickly assembled and disassembled to provide end stops to support side panels without the need for through-ties. The end panels comprise integral handholds for access to the full height of the formwork. The end panels are stackable, rotatable and interchangeable, such that one set of formwork may be used to create several different wall configurations. The finished wall contains an internal support structure and insulating core, without through-holes.
Claims91
A method of constructing a rammed earth structure having a desired height and length, comprising the steps of:
- providing first and second elongated end stop structures extending substantially said desired height;
- mounting said first and second end stop structures in opposed spaced relation to one another;
- mating said first and second end stop structures, thereby defining a cavity;
- inserting a first internal frame within said first end stop structure;
- inserting a second internal frame within said second end stop structure;
- said first and second internal frames being adapted to support an insulating core;
- inserting an insulating core into said cavity such that said insulating core is at least partially supported by said internal frames and extends into said end stops;
- and
- ramming earth into said cavity about said insulating core.

An end stop for use in formwork for constructing rammed earth structures, comprising:
- a first vertical elongated structure comprising a first end face-defining portion and a first brace structure;
- and
- a second vertical elongated structure comprising a second end face-defining structure and a second brace structure;
- said first and second vertical elongated structures being secured to each other.
(canceled)
An end panel for use in formwork for constructing an end face of a rammed earth structure, comprising a vertical elongated structure which comprises an assembly of:
- a partial end face-defining structure comprising a plurality of elongated flat frame members;
- and
- brace structure;
- said partial end-face defining structure defining half of the periphery of said end face.
A kit for constructing a formwork element for constructing rammed earth structures, said kit comprising a vertical elongated structure consisting of:
- a partial end face-defining structure;
- and
- a brace structure.
A formwork system for a rammed earth structure having a desired height and length, comprising:
- first and second elongated end stop structures extending substantially said desired height;
- said first and second end stop structures comprising a plurality of elongated flat frame members;
- said first and second end stop structures mountable in opposed spaced relation to one another;
- and
- a plurality of wall face-defining structures mountable in opposed spaced relation on said mounted first and second end stop structures, thereby defining a cavity.
