Anchor Bolt Presetting Assembly for Precise Foundation Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing practice of 'wet setting' anchor bolts in concrete foundations is discouraged by the International Building Code and Structural Engineers Association, as it does not ensure precise placement and compliance with dimensional requirements, necessitating a method to preset anchor bolts before concrete curing.
Innovation Solution
The Anchor Bolt Setter (ABS) apparatus mechanism assembly, comprising a bolt holder, top plate, lock slider, bushings, and compression nuts, allows for the secure suspension and presetting of anchor bolts in various foundation forms before concrete pouring, ensuring compliance with IBC code requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If anchor bolts are wet set in concrete before curing, then the placement process is simpler and faster, but the placement precision and compliance with dimensional requirements deteriorate
Solution Approach 1:
The invention applies preliminary action by providing a presetting mechanism that positions anchor bolts at precise locations and orientations before concrete is poured. The mechanism includes adjustable arms with positioning pins that can be set to specific coordinates, and the anchor bolts are secured in place using clamps and locking mechanisms before the concrete curing process begins, thereby ensuring compliance with dimensional requirements while maintaining placement efficiency
2Manufacturing precision
If anchor bolts are preset using traditional methods, then placement precision is improved, but the complexity of the presetting mechanism increases
Solution Approach 1:
The presetting mechanism is divided into several independent modules: a base unit with coordinate markings, adjustable positioning arms that can be independently configured, clamping devices that can be attached at different locations, and locking mechanisms. Each module can be adjusted and positioned separately, allowing workers to set up the system for different anchor bolt configurations without requiring a completely different mechanism, thereby reducing overall complexity while maintaining precision
Solution Approach 2:
The mechanism is designed with universal components that can accommodate various anchor bolt sizes, spacing requirements, and foundation types. The positioning arms can be adjusted to different lengths and angles, the clamps can secure different bolt diameters, and the base unit can be positioned on different surface types, allowing a single mechanism to handle multiple presetting scenarios without requiring specialized equipment for each case

AI summary
An Anchor Bolt Setter (ABS) system comprises of several embodiments that work together to suspend an anchor bolt before the concrete is poured into any kind of foundation form regardless of whether or not the concrete is poured to the top of foundation forms. The method of the ABS system works by placing a top plate on the top of any type of foundation form followed by a lock slider for steel forms or nailed down for wood forms, and then the bolt holder is attached it the top plate with a bushing and compression nut that suspends the anchor bolt into place before the concrete is poured. When the concrete is not poured to the top of the foundation forms the wall plate is used and the bolt holder with the anchor bolt is attached to the wall plate thereby suspending the anchor bolt.
