Abstract

One-sided, insulated formwork used in the construction of walls from pourable building material, such as concrete, including an insulating panel connectable to a removable panel by a connecting structure, which may include a permanent reinforcement embedded in the insulating panel. The connecting structure may have a tie removably attachable to the reinforcement, or the reinforcement and tie may constitute a monolithic structure. The tie may be asymmetric in shape to facilitate distribution of loads across the insulating panel, detachment of the removable panel, and enhance the structural integrity of the finished wall.

Claims (10)

1. An asymmetric tie member for connecting and maintaining first and second panels of a formwork for making walls in a fixed, spaced relationship during the wall building process, the first and second panels each having respective inner and outer panel surfaces and a top and bottom, said asymmetric tie having a first end, second end and a length defined as the distance between the first and second ends, the length corresponding, approximately, to a wall thickness described by the space between the first and second panel inner wall surfaces when the first and second panels are connected by said asymmetric tie member, said asymmetric tie member comprising:

a first portion located proximate the first end, said first portion being connectable to the first panel and being located adjacent to the first panel inner wall surface when said asymmetric tie member is connected to the first panel;

a second portion located proximate the second end, said second portion being connectable to the second panel, said second portion having a height substantially less than the height of said first portion; and an intermediate portion extending between said first and second portions;
wherein said asymmetric tie member resists outwardly directed forces applied to the inner panel surfaces.
2. The asymmetric tie member of claim 1, wherein said first portion is releasably engageable with the first panel.
3. The asymmetric tie member of claim 1, wherein said second portion is adapted for releasable engagement with the second panel.
4. The asymmetric tie member of claim 1, 2 or 3, wherein said intermediate portion tapers from said first portion to said second portion.
5. The asymmetric tie member of claim 1, 2, 3, or 4, wherein said asymmetric tie member is triangular in shape.
6. The asymmetric tie member of any one of claims 1 to 5, wherein the first panel is an insulating panel and the second panel is a removable panel.
7. The asymmetric tie member of claim 6, wherein the removable panel is made from a non-insulating material.
8. The asymmetric tie member of claim 6, wherein the removable panel is made from an insulating material.
9. The asymmetric tie member of claim 6, 7 or 8, wherein a space for receiving pourable building material is defined by the distance between the inner wall surfaces of the insulating panel and the removable panel, wherein said asymmetric tie first and second portions are located between the inner wall surfaces.
10. The asymmetric tie member of any one of claims 1 to 9 in combination with first and second dissimilar panels of formwork.
