Panelized Structural Decking With Integrated Joist Rollover Bracing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing structural decking systems require extensive cross-bracing and horizontal bracing between joists to resist rollover and wind uplift forces during installation, which is time-consuming and costly.
Innovation Solution
A panelized system that includes bracing members directly coupled to joists and decking panels, eliminating the need for cross-bracing and horizontal bracing, while providing equivalent uplift and rollover resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If cross-bracing and horizontal bracing are installed between joists to resist rollover and wind uplift forces, then structural stability is improved, but assembly time and material usage increase
Solution Approach 1:
The bracing members are pre-installed on the decking panels before the panels are installed on the building structure. This preliminary action eliminates the need for time-consuming field installation of cross-bracing and horizontal bracing between joists, while still providing the necessary structural stability against rollover and wind uplift forces
Solution Approach 2:
The invention extracts and eliminates the need for separate cross-bracing and horizontal bracing components by integrating the bracing function directly into the decking panel system through pre-installed bracing members that connect the decking panel to the joist, simplifying the overall structure and reducing assembly complexity
2Stability of the object's composition
If cross-bracing and horizontal bracing are installed between joists to resist rollover and wind uplift forces, then structural stability is improved, but material usage and cost increase
Solution Approach 1:
The invention merges the functions of the decking panel and the bracing elements into a single integrated assembly. The bracing members are directly attached to the decking panel, combining what were previously separate components (decking panels and cross-bracing/horizontal bracing) into one unified system that uses less material while maintaining structural stability
Solution Approach 2:
The invention extracts and eliminates the need for separate cross-bracing and horizontal bracing materials by incorporating the bracing function into pre-installed members on the decking panels, thereby reducing the total quantity of structural materials required while maintaining equivalent structural performance
3Device complexity
If bracing members are directly coupled to joists and decking panels, then assembly complexity is reduced, but structural integrity must be maintained
Solution Approach 1:
The bracing members are pre-installed on the decking panels in a controlled manufacturing environment, ensuring proper positioning and secure attachment before field installation. This preliminary action maintains structural integrity by ensuring correct installation while reducing assembly complexity in the field, as the bracing is already in place and requires no additional field installation steps

AI summary
A panelized system for structural decking systems. The panelized system has a plurality of joists operatively coupled together through one or more decking panels. In order to aid in resisting rollover (e.g., the joists rotating with respect to the decking panels and/or support members during installation) bracing members may be utilized. A bracing member may be operatively coupled to a joist (e.g., a lower chord of a joist, web, upper chord, or the like) and to the decking panel (e.g., location on the decking between two joists, such as the mid-point of decking between two joists, or the like). In this way, the joists may be supported directly to the decking instead of having to run cross-bracing (e.g., x-shaped, or the like) between each of the joists. Once the panelized system is assembled on the ground, the panelized system may be lifted into place and assembled to a building.
