Concrete Boss Anchor Thread Engagement via Tapered Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete anchors lack efficient mechanisms for transferring loads to concrete structures and providing reinforcement against forces like earthquakes and high winds, with existing solutions often increasing the thickness of the base section to achieve thread engagement, which can be cumbersome and inefficient.
Innovation Solution
The development of anchor bodies with boss openings and threaded rods, where the boss section is tapered and circular in cross-section, allowing for thread engagement without increasing the base section thickness, and the use of various anchor assemblies and stud rails with threaded openings to securely embed rods and plates within concrete structures.

Engineering Contradiction Analysis
1Length of moving object
If the base section thickness is increased to achieve thread engagement, then the thread engagement length is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The patent transitions from achieving thread engagement through increased base thickness (one-dimensional solution) to creating a boss opening that extends through the base section (three-dimensional solution). This allows threaded rods to engage with the concrete structure through the boss opening, providing sufficient thread engagement length without increasing the overall base thickness.
Solution Approach 2:
The anchor base is segmented into distinct functional portions: a base section for embedding in concrete, a boss section with openings for threaded rod engagement, and a flange section for load distribution. This segmentation allows the threaded rods to engage through the boss openings without requiring the entire base section to be thicker.
2Length of moving object
If the base section thickness is increased to achieve thread engagement, then the thread engagement length is improved, but the ease of operation and installation are reduced
Solution Approach 1:
The boss openings provide a direct pathway through the base section, allowing threaded rods to be installed from the top surface without requiring excessive base thickness. This dimensional approach simplifies installation while maintaining adequate thread engagement length within the concrete structure.
Solution Approach 2:
The boss openings are pre-formed in the base section during anchor fabrication, eliminating the need for现场 drilling or complex installation procedures. This preliminary preparation of engagement paths significantly ease of operation during installation.
3Strength
If the base section thickness is increased to achieve thread engagement, then the load transfer capability is improved, but the productivity and installation efficiency decrease
Solution Approach 1:
The boss openings create vertical engagement paths that allow threaded rods to achieve sufficient thread engagement length without increasing horizontal base thickness. This maintains load transfer capability through effective concrete-rod engagement while preserving installation efficiency.
Solution Approach 2:
The boss sections with openings are strategically positioned at locations requiring threaded rod engagement, concentrating the structural functionality where needed. This localized approach maintains load transfer capability at critical points without requiring uniform increases in base thickness throughout the entire anchor.

AI summary
An anchor assembly for being embedded in concrete includes a metal plate including an opening, the metal plate including a top surface and bottom surface; the opening including a wall extending from the top surface or the bottom surface; and a threaded rod operably attached to the metal plate.
