Flush-Mount Anchor Bolt Assembly for Concrete Surface Finishing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor bolt systems protrude above the concrete slurry surface during installation, complicating finishing processes and requiring cumbersome lifting of construction elements during attachment.
Innovation Solution
An improved anchor bolt fastener assembly with a float design that allows the anchor bolt to be installed flush with the concrete slurry, featuring a threaded bore, inner receiving chamber, and outer slurry contact surface, enabling flush installation and simplified attachment of construction elements using specialized fastener studs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If anchor bolts are installed protruding above the concrete slurry surface, then the threaded portion is accessible for fastening construction elements, but the surface finishing process becomes complicated and time-consuming
Solution Approach 1:
The anchor bolt is divided into two functional segments: a submerged threaded portion for fastening and a protruding unthreaded portion for surface finishing. This segmentation allows the threaded portion to remain accessible while the protruding portion can be easily trimmed after curing, resolving the contradiction between fastening accessibility and surface finishing efficiency
Solution Approach 2:
The unthreaded portion of the anchor bolt acts as an intermediary element that extends above the slurry surface during installation to enable proper embedding and orientation, but is later removed or trimmed. This intermediary structure facilitates both the installation process and the subsequent surface finishing by providing a temporary guide that can be easily eliminated
2Stability of the object's composition
If anchor bolts protrude above the concrete slurry surface, then proper embedding and orientation are achieved, but construction elements must be lifted higher during attachment, increasing installation difficulty
Solution Approach 1:
The system transitions from a static protruding anchor bolt to a dynamic two-stage configuration: initially protruding to ensure proper embedding and orientation, then becoming flush with the surface after curing. This dynamic adjustment eliminates the need for high lifting while maintaining the stability benefits of proper embedding
Solution Approach 2:
The anchor bolt is preliminarily installed with a protruding unthreaded portion to ensure correct embedding and orientation during the concrete pouring process. This preliminary configuration guarantees proper positioning, and the protruding portion is later trimmed to eliminate lifting difficulties during the attachment phase
3Productivity
If anchor bolts are installed flush with the concrete slurry surface, then surface finishing is simplified, but the threaded portion must be fully submerged which complicates fastening access
Solution Approach 1:
The anchor bolt is segmented into a submerged threaded portion for fastening and a temporary protruding unthreaded portion for surface finishing. This segmentation allows the threaded portion to remain accessible for fastening operations while the protruding portion can be easily trimmed to achieve a flush surface, resolving the contradiction between surface finishing simplicity and fastening accessibility

AI summary
An anchor bolt fastener assembly with specialized connection capabilities and features for attaching building components to concrete slabs, walls, ceilings, and/or structural surfaces. Compression force can be established and maintained over time using a compression washer in combination with a specialized fastener stud that is designed to exploit the compression washer benefits. Methods of using exemplary embodiments include installing the anchor bolt fastener assembly relatively flush with the surface of the concrete slurry by direct insertion in the slurry using a specialized threaded anchor bolt float. Once the slurry hardens, the anchor bolt and anchor bolt float embedded in the concrete slurry cooperate with the specialized fastener stud to secure the building component to the concrete.
