Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for coupling precast concrete panels and reinforcing bars are time-consuming and require precise alignment, often relying on grout and lengthy curing processes, which limits efficiency and flexibility in construction.
Innovation Solution
A reinforcing bar coupler assembly with a clamp ring and insert system that allows for variable placement and secure coupling of reinforcing bars, enabling easy alignment and attachment of precast panels without the need for exact alignment, using a threaded system and spring mechanism for clamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If grout and curing process are used to secure precast panels together, then the panels can be securely connected, but the construction time is significantly increased due to waiting for grout to cure
Solution Approach 1:
The invention extracts and eliminates the grout material and curing process from the panel connection system. Instead of using grout that requires curing time, the patent employs a mechanical coupling system with couplers that directly secure reinforcing bars, allowing immediate structural integrity without waiting for material curing.
Solution Approach 2:
The invention replaces the chemical/thermal curing process with a purely mechanical fastening system. The coupler assembly uses mechanical components (coupler body, locking mechanism, set screws) to secure reinforcing bars, substituting the time-consuming grout curing process with immediate mechanical engagement.
2Reliability
If precise alignment of reinforcing bars is required for panel coupling, then secure connection can be achieved, but the ease of operation and placement flexibility is reduced
Solution Approach 1:
The invention changes the tolerance parameters of the coupling system. The coupler body is designed with enlarged openings and adjustable locking mechanisms that accommodate variations in reinforcing bar position and orientation, allowing secure connection even when bars are not precisely aligned during panel placement.
Solution Approach 2:
The coupling system incorporates dynamic adjustment capabilities through movable locking components and adjustable set screws. This allows the coupler to adapt to varying bar positions and achieve secure mechanical engagement without requiring precise pre-alignment, enhancing operational flexibility during construction.

AI summary
A system and method for attaching precast panels and for coupling a plurality of reinforcing bars together. The system and method have a plurality of reinforcing bar coupler assemblies as shown to mechanically splice reinforcing bars of two precast panels or a plurality of reinforcing bars together to provide a permanent means of connecting the panels. Each of the reinforcing bar coupler assemblies have a first component, clamp ring, insert and second component and spring that are assembled and used to couple a plurality of reinforcing bars together. The reinforcing bar coupler assembly is precast into precast panels that are then adapted to be mounted and coupled together using the reinforcing bar coupler assemblies.
