Suspended Concrete Frame with Anchor Bolt Templates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for constructing concrete footings are time- and labor-intensive due to the difficulty in achieving proper alignment and placement of anchor bolts, which slows down the construction process.
Innovation Solution
A frame system is suspended over an excavation, allowing anchor bolts to be cast in place as the footing is formed, with the frame system including templates for precise alignment and placement of anchor bolts before concrete is poured, enabling rapid and high-precision placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional methods are used for constructing concrete footings with manual placement of anchor bolts, then flexibility in construction approach is maintained, but construction time and labor intensity increase significantly
Solution Approach 1:
The frame system is assembled with templates and anchor bolts positioned in advance before being suspended over the excavation. This preliminary preparation eliminates the need for time-consuming on-site alignment and placement operations, directly addressing the productivity improvement while managing device complexity through standardized pre-assembly procedures
Solution Approach 2:
The frame system acts as an intermediary device that holds and positions multiple components (templates, anchor bolts, forms) in precise relationships. This intermediary structure enables rapid transfer of pre-positioned components to the final footing location, resolving the contradiction between construction speed and system complexity
2Manufacturing precision
If manual alignment and placement of anchor bolts is performed, then adaptability to various site conditions is maintained, but placement precision deteriorates
Solution Approach 1:
Templates are used as physical copies or patterns that replicate the precise geometric relationships and positions of anchor bolts. These templates are manufactured with high precision and transferred to the construction site through the frame system, ensuring consistent accurate placement without requiring complex manual measurement and alignment operations
Solution Approach 2:
The precise geometric relationships and positions of anchor bolts are predetermined and fixed in the templates during manufacturing. This preliminary establishment of precision eliminates the need for complex on-site operations while maintaining high placement accuracy, directly resolving the contradiction between precision and operational simplicity

AI summary
Systems and methods for constructing concrete foundations are provided which allow for rapid and high-precision placement and alignment of anchor bolts across large distances. A frame system is constructed outside of an excavation and then suspended, using supports, over an excavation. The frame system can include a frame having one or more templates for anchor bolts, a form suspended from the frame, and a mat and cage assembly tied to the frame. The frame system can be aligned in proper position and the anchor bolts placed in the frame system before the concrete is placed. In this way, the anchor bolts can be cast in place as the footing is placed.
