Light Gauge Steel Deck Frame With Integral Attachment Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deck framing systems using treated lumber are often cumbersome and inefficient in assembly, and light gauge steel alternatives require complex attachment methods that complicate fabrication and assembly.
Innovation Solution
A deck framing system utilizing light gauge steel components with integral tabs on perimeter support members for simplified assembly, where tabs on the joist support walls and web walls facilitate secure attachment of floor support joists, allowing for efficient formation and assembly of the deck frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional treated lumber is used for deck framing, then assembly is straightforward with traditional techniques, but the system is cumbersome and inefficient
Solution Approach 1:
The patent combines the perimeter support member and floor support joist into a single integrated light gauge steel component. The joist is formed with a continuous profile that includes both the horizontal floor support portion and the vertical perimeter support portion, eliminating the need for separate members and complex joinery while improving assembly efficiency
2Strength
If light gauge steel is used for deck framing, then structural strength and durability are improved, but attachment methods become complex and fabrication is complicated
Solution Approach 1:
The light gauge steel joist is pre-formed during manufacturing with integrated attachment features including tabs, slots, and holes positioned at specific locations. These attachment features are incorporated into the continuous profile during the forming process, simplifying both fabrication and subsequent assembly while maintaining structural strength
3Adaptability or versatility
If multiple separate components are used for deck framing, then adaptability and load distribution are improved, but assembly time and complexity increase
Solution Approach 1:
The patent merges multiple functional components into a single continuous light gauge steel joist that provides both floor support and perimeter support functions. The integrated design maintains load distribution capabilities while significantly reducing the number of parts to be assembled and the time required for assembly

AI summary
A deck frame includes at least one perimeter support member that has a joist support wall, and a web wall extending perpendicularly from the joist support wall. A plurality of first attachment tabs extend from the web wall and are disposed spaced apart along the length of the at least one perimeter support member. A plurality of second attachment tabs extend from the web wall and are disposed spaced apart along the length of the at least one perimeter support member. Each one of a plurality of joists has a first lateral wall and a second lateral wall disposed opposite the first lateral wall. One of the plurality of first attachment tabs is configured to be secured to the first lateral wall, and one of the plurality of second attachment tabs is configure to be secured to the second lateral wall of each one of the plurality of joists.
