Concrete Anchor Rod Securement Device with Removable Headless Nails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for positioning and securing anchor rods in concrete structures are inefficient, requiring costly adjustments to framing structures, wasting materials, and being time-consuming, with exposed metallic elements needing subsequent removal or modification.
Innovation Solution
A securement device with a rod receiver and nail housing that allows for precise positioning and securement of anchor rods within concrete forms, featuring a headless nail that can be easily removed with the framing deck, leaving no exposed metallic elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional framing structures are used to position anchor rods, then anchor rods can be secured, but adjustment of location requires costly and time-consuming modification of the framing structure
Solution Approach 1:
The device separates the positioning function from the framing structure by using an independent adjustable mechanism. The anchor rod holder is segmented into adjustable components that can be repositioned without modifying the framing structure, enabling flexible location changes while maintaining structural integrity.
Solution Approach 2:
The device introduces dynamic adjustability through a mechanism that allows the anchor rod holder to be repositioned along the framing structure. This dynamic capability enables location changes without costly and time-consuming structural modifications, directly resolving the contradiction between adaptability and time loss.
2Ease of operation
If traditional securement devices are used, then anchor rods can be positioned, but exposed metallic elements require subsequent removal, cutting, or grinding
Solution Approach 1:
The device extracts the securement function from permanent metallic elements by using framing deck nails that are removed with the decking. The nail housing is designed to be temporarily attached during construction and then completely removed, taking the securement function with it and leaving no harmful exposed metallic elements in the concrete.
Solution Approach 2:
The device uses disposable nail housing components that are inexpensive and intended for single-use during construction. These components are easily removed with the framing decking, eliminating the need for costly subsequent removal, cutting, or grinding of permanent metallic securement elements.
3Manufacturing precision
If precise positioning of anchor rods is achieved, then accuracy is improved, but device complexity increases
Solution Approach 1:
The device achieves precise positioning through a universal adjustable mechanism that can accommodate various anchor rod locations without requiring complex custom-designed components. The same basic structure provides accurate positioning across multiple positions, reducing overall device complexity while maintaining high positioning accuracy.

AI summary
A securement device having a rod receiver attachable to the end of an anchor rod, the securement device having a headless nail slidably extendable from a first position within the device to a second position protruding outwardly from the end of the securement device opposite the rod receiver, and a method of positioning and securing an anchor rod attached to the securement device in a desired location on a concrete form deck within a rebar structure for a concrete formation, so that the headless nails may release from the securement device body when the deck is removed after the concrete sets, leaving an innocuous nail void in the concrete that may serve as a functional attachment recess.
