Color-Coded Anchor Bolt Suspension for Concrete Form Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor bolt suspension systems in concrete form framing lack inspection convenience and form integrity, leading to increased labor costs and potential mistakes in anchor bolt placement and selection before concrete is poured.
Innovation Solution
A polymeric anchor bolt suspending structure with color-coded, rectangular segments and resilient split tube retainers that provide visual indications of bolt size and spacing, ensuring correct selection and positioning, while bracing the concrete form and shielding threads from cement, facilitating easy inspection and correct placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anchor bolt suspension systems are used, then anchor bolts can be positioned in concrete forms, but inspection convenience and form integrity are compromised
Solution Approach 1:
The patent applies color coding to the suspending structure components, where different colors indicate different anchor bolt sizes or positions. This allows inspectors to quickly verify correct bolt selection and placement at a glance, improving inspection convenience while maintaining form integrity through proper positioning.
Solution Approach 2:
The suspending structure is divided into multiple segments that can be independently positioned and secured to form walls. This segmentation allows for easier inspection of individual segments and their corresponding anchor bolts, while the assembled structure maintains the required form integrity throughout the concrete pouring process.
2Productivity
If anchor bolts are suspended without visual indications, then placement can be performed, but selection and inspection become difficult
Solution Approach 1:
Visual indicators in the form of color-coded segments or markers are integrated into the suspending structure. These color indicators correspond to specific anchor bolt sizes or positions, enabling workers to quickly identify correct bolt selections and positions during installation, thereby maintaining placement efficiency while eliminating the difficulty of bolt size identification.
3Ease of manufacture
If exposed threads are not protected, then anchor bolts can be installed, but threads may be coated by wet cement
Solution Approach 1:
The suspending structure itself serves as an intermediary protective element. The segments or retainers positioned on the form walls physically shield the exposed anchor bolt threads from contact with wet cement during the pouring process. This protection is achieved without complicating the installation process, as the protective function is integrated into the existing suspending structure.

AI summary
A self-checking anchor bolt suspension assembly includes an array of suspension segments each including equally sized openings distributed in a spaced relationship therein for engaging in suspension resilient tubular caps provided with annular tapered cavities communicating through annular apertures at the lower ends thereof. The aperture size and the cavity taper are selected so that the threaded shank of an anchor bolt of only a singular dimensional increment is receivable and resiliently grasped therein and the caps are each color coded in accordance with the shank size of the bolt. In this manner the color coding provides a quick visual assurance that only the properly sized anchor bolts are deployed for immersion into the poured concrete.
