Insulated Concrete Form Holder for Foundation Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for positioning insulated concrete forms (ICF) on building footers are labor-intensive and prone to misalignment, leading to potential water leakage and increased construction time, as they require precise leveling and alignment, which is challenging due to the fluid state of concrete during placement.
Innovation Solution
The use of an insulated concrete form holder that integrates the first course of ICFs with the foundation, featuring a support surface and adjustable upright portions to secure the forms in place, ensuring they are level and aligned without the need for constant adjustment, and includes a bar support surface for reinforcing rebar, allowing for easier and faster construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional methods are used to position insulated concrete forms on building footers, then the forms can be placed on the footer, but the process is labor-intensive and prone to misalignment requiring constant adjustment
Solution Approach 1:
The holder is pre-installed on the footer with upright portions positioned at predetermined locations before the ICFs are placed. This preliminary positioning of the support structure eliminates the need for constant adjustment during ICF installation, as the forms simply need to be placed against the pre-positioned upright portions.
Solution Approach 2:
The holder acts as an intermediary device between the footer and the insulated concrete forms. It provides a stable, pre-positioned interface that facilitates easy alignment and positioning of the ICFs without requiring direct manual adjustment of the forms themselves.
2Manufacturing precision
If precise leveling and alignment are attempted manually during concrete pouring, then some alignment can be achieved, but the fluid state of concrete makes constant adjustment necessary
Solution Approach 1:
The upright portions of the holder are pre-positioned at exact predetermined locations before the concrete is poured. This advance positioning ensures precise alignment references are available before the ICFs are installed, eliminating the need to achieve alignment during the concrete pouring process when materials are in a fluid state.
Solution Approach 2:
The holder with its pre-positioned upright portions serves itself by providing built-in alignment references that automatically guide the correct positioning of the ICFs. The system self-regulates alignment without requiring external adjustment mechanisms or constant manual intervention during the pouring process.
3Reliability
If the first course of ICFs is integrated with the foundation, then water leakage is minimized and construction continuity is improved, but a specialized holder system is required
Solution Approach 1:
The holder system is segmented into a base portion that attaches to the footer and upright portions that extend upward. This segmentation allows the holder to provide specialized integration functionality at the critical footer-ICF interface without requiring the entire ICF system to be complex, maintaining simplicity elsewhere.
Solution Approach 2:
The holder serves multiple functions: it provides structural support for the first course of ICFs, ensures precise alignment through pre-positioned upright portions, facilitates integration with the foundation, and prevents water leakage at the interface. This multi-functionality achieves reliable integration without requiring multiple separate complex systems.

AI summary
An insulated concrete form holder is provided for holding insulated concrete forms that form the first course of a wall so that the first course of insulated concrete forms are formed integrally with the foundation of a building. The form holder has a support surface for supporting the form holder in a foundation form and a form support surface for contacting the bottom of the insulated concrete form and supporting the insulated concrete form thereon. The form support surface is positionable between the top and the bottom of the foundation form, said form support surface is spaced from the top of the foundation form a distance less than the height of the insulated concrete form so that the top of the insulated concrete form is positionable above the top of the foundation form. The form holder includes form support upright portions extending upwardly from the form support surface for contacting the sides of the insulated concrete form and restraining lateral movement of the insulated concrete form.
