Corrugated Bridging Member for Steel Stud Torsional Bracing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Steel stud building wall systems face challenges in resisting lateral and torsional loads, particularly during fires when metal studs twist or bend, leading to loss of structural integrity and increased damage.
Innovation Solution
The use of channel-shaped bridging members with mounting sections and notches that interlock with the central web of steel studs, providing enhanced torsional rigidity and stability without the need for fasteners, allowing for quick installation and strong connections in various wall environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If channel-shaped bridging members are used to closely fit the openings in steel studs, then torque resistance is maximized, but some twisting can still occur and additional brackets with separate fasteners are needed to prevent shifting or bending
Solution Approach 1:
The patent combines the bridging member and bracket functions into a single integrated component. The bridging member includes integrated bracket portions at its ends that can be directly fastened to the studs, eliminating the need for separate bracket components and fasteners while maintaining both torque resistance and shift prevention capabilities
Solution Approach 2:
The bridging member is designed to perform multiple functions simultaneously: it provides torque resistance through its channel shape that closely fits the stud openings, prevents shifting or bending through integrated bracket portions, and allows for quick installation through self-contained fastening capabilities
2Ease of operation
If short bridging members with fixed lengths are used to span adjacent studs, then installation is simplified, but adaptability to various wall environments is limited
Solution Approach 1:
The bridging member is designed with adjustable length capabilities through telescoping sections that allow the member to be extended or retracted to match different stud spacings. This dynamic adjustment feature maintains installation simplicity while significantly improving adaptability to various wall environments and stud configurations
3Strength
If elongated bridging members with slots are used to mate with the central web of wall studs, then connection strength is improved, but installation time increases
Solution Approach 1:
The bridging member is pre-assembled with integrated bracket portions and fasteners attached during manufacturing. This preliminary preparation allows the member to be installed as a complete unit without requiring on-site assembly of multiple components, thereby maintaining strong connections while significantly reducing installation time

AI summary
A building connection between a plurality of vertical wall studs made with one or more bridging members to brace the wall studs. The one or more bridging members are formed with mounting sections that are received in openings of the wall studs and the mounting sections are bracketed by end sections where bridging members can overlap. The bridging members interface with the web of the wall studs to brace them.
