Construction Hanger Brace With Bonded Guide Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction hangers for concrete forms are often unrecoverable after concrete hardening, leading to high replacement costs, and they lack efficient load distribution mechanisms, which can result in premature failure of support members.
Innovation Solution
A construction hanger comprising a brace with a guide member bonded to a substantially flat metal plate, featuring an arm that engages beam profiles and a guide with an angled major axis, along with optional bearing plates for load distribution, allowing for secure attachment and load transfer to construction support members like I-beams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional welded hangers are used, then structural strength is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The hanger is divided into two separate components: a brace that engages the beam and a guide member that receives the hanger rod. These components are bonded together using adhesive instead of welding, simplifying manufacturing while maintaining structural integrity. The segmentation allows each component to be optimized independently for its specific function.
Solution Approach 2:
The patent replaces the welding process (thermal-mechanical system) with a bonding system using adhesive (chemical-mechanical system). This substitution eliminates the complexity of welding operations, equipment requirements, and skill demands while achieving comparable or superior joint strength through proper adhesive selection and application.
2Reliability
If hangers are designed for secure load bearing, then reliability improves, but ease of manufacture decreases
Solution Approach 1:
By segmenting the hanger into a brace and guide member, the design allows for simplified manufacturing of each component while maintaining overall reliability. The brace can be manufactured as a simple bent steel bar, and the guide member as a separate casting or formed piece, both of which are easier to produce than integrated welded designs.
Solution Approach 2:
Replacing welding with bonding simplifies the manufacturing process by eliminating complex welding procedures, reducing skill requirements, and enabling assembly line production. The bonding process can be automated more easily than welding, improving ease of manufacture while maintaining reliable load-bearing capacity through properly engineered adhesive joints.
3Volume of moving object
If hangers support forms from within form volume, then space utilization improves, but loss of substance increases due to unrecoverability
Solution Approach 1:
The hanger design enables dynamic reuse by allowing the guide member to be detached and repositioned for subsequent concrete placements. Unlike traditional fixed welded hangers, this design permits the hanger components to be recovered, inspected, and reused multiple times, reducing material loss and waste while maintaining efficient space utilization within the form volume.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a cost-effective, recoverable hanger system that effectively distributes loads, reducing the risk of support member failure and enabling efficient reuse, while ensuring secure attachment of form members to construction support elements.
Implementation Method 1
The guide member is bonded to the brace by means of welding, one or more fasteners, an interference fit, or other technique known to those having skill in the art.
