Truss Reinforcement Bracket Resisting Lateral Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for reinforcing roof trusses are inadequate in resisting horizontal or shear loads, such as those experienced during earthquakes or windstorms, as they do not provide substantial resistance to lateral forces.
Innovation Solution
An apparatus comprising a center socket and end sockets with braces that securely interlock adjacent trusses, transferring lateral loads through rigid elongate members to enhance the structural integrity and resistance to rotational forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If decking material is applied over trusses to provide additional rigidity, then resistance to forces altering spacing between trusses is improved, but resistance to lateral loads such as earthquakes or windstorms remains insufficient
Solution Approach 1:
The invention transitions from planar reinforcement (decking material applied horizontally over trusses) to three-dimensional reinforcement by adding vertical bracing elements that connect adjacent trusses at multiple levels. The bracket assembly extends vertically with braces positioned at different heights, creating a spatial framework that resists lateral loads through multi-dimensional structural interconnection.
Solution Approach 2:
The reinforcement system is divided into discrete modular components including individual brackets, braces, and fasteners that can be independently installed between adjacent trusses. Each bracket assembly acts as a separate reinforcement unit that can be applied systematically along the truss span, allowing progressive strengthening without requiring complete dismantling or complex integrated structures.
2Ease of manufacture
If conventional reinforcement methods are used, then ease of manufacture is maintained, but structural integrity against rotational forces is insufficient
Solution Approach 1:
The bracket assemblies are pre-configured with integrated fastening components and pre-positioned braces designed to engage with standard truss dimensions. The brackets include pre-formed flanges and attachment points that align with typical truss geometry, allowing workers to install the reinforcement system using conventional tools and procedures without requiring complex custom fabrication or specialized assembly techniques.
Solution Approach 2:
The reinforcement system combines multiple materials including metal brackets and braces for structural strength, wood or composite blocking for spacing maintenance, and fasteners for connection. This composite approach integrates materials with complementary properties to achieve enhanced resistance to rotational and lateral forces while maintaining compatibility with existing wood or metal truss structures.

AI summary
An apparatus for supporting a plurality of parallel spaced apart trusses comprises a center socket and first and second end sockets. The center socket is sized to receive a top edge of a first truss therein whereas the first and second end sockets are each sized to receive a bottom edge of adjacent second and third truss therein. The apparatus further comprises a first brace extending between the first end socket and the center socket and a second brace extending between the second end socket and the center socket. The base panel of the first and second end sockets define a first plane substantially parallel to the bottom edges of the plurality of trusses and the base panel of the center socket defines a second plane substantially parallel to the top edge of the plurality of trusses and second plane is angularly oriented relative to the first plane.
