Concrete Anchor Holder With Offset Toe for Precise Form Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete anchor systems fail to securely anchor structures to foundations during construction, particularly in areas prone to natural disasters, and lack visibility for proper placement, necessitating removal before concrete hardening.
Innovation Solution
A concrete anchor holder with an 'L' shaped toe and nail holes, allowing upside-down use during pouring, and a window for visual alignment, ensuring secure anchoring without removal and enabling accurate placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anchor holders are used during concrete pouring, then the anchors can be positioned on the foundation, but the holders must be removed before the concrete hardens
Solution Approach 1:
The holder is designed to be inverted during concrete pouring, with the cup portion embedded in the concrete and the flange remaining exposed. This inversion allows the holder to serve its anchoring function permanently without requiring removal, resolving the contradiction between reliable positioning and the complexity of removal.
Solution Approach 2:
The holder's own structural components (cup and flange) serve dual purposes: the cup embeds in concrete to provide anchoring, while the flange remains exposed to secure the anchor. The holder serves itself by using its inverted configuration to simultaneously achieve both concrete embedding and anchor retention without external intervention or removal.
2Manufacturing precision
If anchor holders are positioned during concrete pouring, then anchors can be secured to the foundation, but visibility for accurate placement is insufficient
Solution Approach 1:
The holder is made from brightly colored plastic material that provides high visual contrast against the concrete and surrounding environment. This color property enables workers to easily detect and align the holder during concrete pouring, achieving accurate anchor placement without requiring additional marking or visibility enhancement measures.
3Reliability
If the anchor holder is embedded in concrete, then the anchor can be retained on the foundation, but the holder cannot be adjusted or repositioned
Solution Approach 1:
The holder is positioned and aligned with visible accuracy during concrete pouring before the concrete hardens. The bright color and clear geometric features enable preliminary positioning adjustments to be made while the concrete is still fluid, ensuring correct placement before the holder becomes permanently fixed in the hardened concrete.

AI summary
Improvements in a concrete anchor holder that has an “L” shaped toe that comes down from where an anchor is placed. The toe allows for an offset from the anchor holder to position the anchor a required distance from the batter boards into the area of the foundation where the cement will be poured. The toe includes a plurality of nail holes being level with each other allow for this hanger to be used upside down in an offset condition to suspend the anchor in the foundation/footing above or below the foundation framing boards. The holder includes a window that allows a visual inspection to the form board to allow the user the ability to see where they have marked their hardware prior to the hanging process.
