Ribbed Metal Decking for Structural Diaphragm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of installing composite decking in buildings is time-consuming and expensive due to the need for a contiguous metal sheet, concrete pouring, and mesh placement to form a structural diaphragm, which complicates the connection to structural elements and increases costs.
Innovation Solution
A standardized metal deck with a ribbed structure is used, allowing it to function as a floor or ceiling without concrete, reducing manufacturing costs and eliminating the need for repeated engineering designs, and can be manufactured using cold roll former machines, with options for concrete pouring for noise dampening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If composite decking is used with concrete and mesh structure, then structural integrity is improved, but manufacturing cost and installation time increase
Solution Approach 1:
The patent extracts and eliminates the concrete and mesh components from the composite decking system, replacing them with a self-supporting metal deck structure that has integrated ribs and flutes providing the necessary structural integrity without requiring additional materials or installation steps
Solution Approach 2:
The patent merges the structural support function into the metal deck itself by forming integrated ribs and flutes that provide rigidity and strength, combining what were previously separate components (metal deck, concrete, mesh) into a single unified structure
2Stability of the object's composition
If composite decking with concrete is used, then structural diaphragm is completed, but connection to structural elements becomes complex
Solution Approach 1:
The patent removes the concrete and mesh layer that complicated the connection process, leaving a simplified metal deck structure that can be directly connected to structural elements through its integrated ribs and flutes, reducing connection complexity while maintaining diaphragm stability
3Ease of manufacture
If standardized metal deck is used, then manufacturing cost is reduced, but sound insulation capability decreases
Solution Approach 1:
The patent applies local quality by creating elevated sections at specific locations on the metal deck that provide sound insulation where needed, while maintaining the standardized, cost-effective metal deck structure in other areas, thus balancing manufacturing efficiency with acoustic performance
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 standardized metal deck provides structural integrity without the expense and time of concrete pouring, simplifying installation and reducing costs, while allowing for noise dampening when concrete is applied, and can be easily integrated with other building components.
Implementation Method 1
the elevated section configured to provide sound insulation between the metal deck and a truss structure
Implementation Method 2
the ribbed section including a rib flute extending from a bottom surface of the metal deck

AI summary
In one implementation, a metal deck is provided that includes one or more deck components formed in a contiguous metal sheet. Each of the deck components includes one or more folded ribs formed along the length of the metal deck. Each of the one or more folded ribs are configured such that one or more trusses of a building may fit between the one or more folded ribs. The metal deck may be used to complete the structural diaphragm without using concrete.
