ABSTRACT:
FIELD OF THE INVENTION
This invention relates to an insulated concrete form and, in particular, to a web for an insulated concrete form.
BACKGROUND OF THE INVENTION
Insulated concrete forms allow concrete foundations and walls to be poured and insulated at the same time. Each form comprises a pair of spaced foam panels separated by webs extending between the panels.
The webs are important in that they should be sturdy enough to provide a form that is stable and strong and yet does not interfere with the pouring of the concrete into the form.
It is accordingly an object of the present invention to provide a web for an insulated concrete form which satisfies the above requirements.
SUMMARY OF THE INVENTION
According to the invention there is provided a web for an insulated concrete form comprising a pair of opposed web elements and a pair of connectors for connecting the web elements together in spaced relationship, the web elements and the connectors being provided with mutually interengaging formations whereby the web elements and the connectors are rigidly held together in a plane.
Each web element may comprise a flat strip provided with a non-circular tube on one side forming said mutually interengaging formation on the web element for engaging with one of the connectors.
Each connector may comprise a steel bar and wherein said mutually interengaging formations on the connector comprise V-shaped or U-shaped hook formations at its opposite ends, respectively, for engaging with the non-circular tube on each of said opposed web elements.
Also according to the invention there is provided an insulated concrete form comprising a pair of opposing panels of a thermal insulating material which are connected together in spaced relationship by means of a plurality of the webs as described.
Further objects and advantages of the invention will become apparent from the description of preferred embodiments of the invention below.
