Anchor Bolt Setter Assembly for Accurate Pre-Pour Form Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for setting anchor bolts in concrete foundations, such as wet setting, are inefficient and not applicable for all types of concrete foundation forms, particularly failing to address the placement requirements for anchor bolts in concrete slabs and not meeting safety standards as per the International Building Code.
Innovation Solution
The Anchor Bolt Setter system, comprising a bolt cap and adapter mechanism, securely positions anchor bolts before concrete pouring by engaging with foundation forms, ensuring accurate placement and easy removal after concrete curing, using various adapters for different foundation types and allowing for precise positioning and secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wet setting method is used to place anchor bolts, then the process is simple and commonly used, but it fails to meet safety standards and is not applicable for all types of concrete foundation forms
Solution Approach 1:
The anchor bolt is positioned and secured in the bolt cap before the concrete is poured. The bolt cap with anchor bolt is pre-assembled and attached to the foundation form, ensuring proper positioning before the concrete sets, eliminating the need for wet setting after pouring.
Solution Approach 2:
The bolt cap serves as an intermediary device that holds the anchor bolt in the correct position and transfers it to the concrete foundation. The adapter acts as another intermediary that connects the bolt cap to the foundation form, enabling precise positioning and secure attachment during the concrete pouring process.
2Device complexity
If traditional anchor bolt setting methods are used, then the process is simple, but it lacks adaptability for different foundation forms and concrete slab requirements
Solution Approach 1:
The system employs multiple adapter types (first adapter for foundation forms, second adapter for concrete slabs, third adapter for vertical positioning) that can be selected based on the specific application. This modular approach with universal bolt cap design allows the same basic mechanism to adapt to different foundation forms and concrete pouring scenarios.
Solution Approach 2:
The anchor bolt setting system is divided into separate functional components: the bolt cap that holds the anchor bolt, the adapter that attaches to different foundation forms, and the locking mechanism. This segmentation allows each component to be optimized for its specific function while maintaining overall system versatility.
3Ease of operation
If anchor bolts are placed manually, then the process is flexible, but it is time-consuming and prone to positioning errors
Solution Approach 1:
The bolt cap is designed with self-aligning features and dimension marks that automatically guide the anchor bolt to the correct position. The adapter includes alignment features that self-adjust to the foundation form geometry, reducing the need for manual measurement and adjustment while ensuring accurate positioning.
Solution Approach 2:
The manual measurement and positioning process is replaced by pre-marked dimension indicators on the adapter and bolt cap. The mechanical alignment features and locking mechanisms automatically ensure correct positioning, eliminating the need for continuous manual measurement and adjustment during installation.
4Manufacturing precision
If anchor bolts are set before concrete pouring, then proper positioning is achieved, but the setting mechanism must be easily removable after curing
Solution Approach 1:
The locking mechanism transitions from a locked state during concrete pouring to an unlocked state for removal. The adapter is designed to be securely attached during the concrete setting process but can be easily released after curing, allowing the system to adapt its fixation strength based on the operational phase.
Solution Approach 2:
The adapter and bolt cap assembly is designed as a temporary setting mechanism that is discarded (removed) after serving its purpose of positioning the anchor bolt during concrete pouring. The anchor bolt itself is recovered and remains in the foundation, while the setting mechanism is removed and can be reused or discarded.

AI summary
An Anchor Bolt Setting (ABS) system has a bolt cap adapted to securely hold an anchor bolt vertically by an upper threaded end, with the anchor bolt suspended below the bolt cap, and an adapter having a first interface shaped to engage an edge of a foundation form for concrete, a substantially planar portion extending over the foundation form from the edge, and a second interface in the planar portion shaped to engage and suspend the bolt cap, with the anchor bolt suspended downward. The anchor bolt is threaded into the bolt cap, the adapter is engaged to the edge of the foundation form extending horizontally over the foundation form, the bolt cap with the anchor bolt engaged is engaged to the second interface of the adapter, presenting the anchor bolt downward into the foundation form, and uncured concrete is poured into the foundation form, enveloping the anchor bolt.
