Integrated Platform Joist System for Rapid Deck Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern joist systems in construction require substantial time to erect and are dependent on skilled labor, limiting efficiency and availability.
Innovation Solution
An integrated platform joist system with web and deck portions that are integrally formed, allowing for nested engagement and secure fastening, providing increased structural rigidity and flexibility in alignment, and can be manufactured from lightweight materials like galvanized steel or composite materials for ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional joist systems are used with separate web and deck portions requiring multiple fastening means, then structural support is provided, but assembly time increases and labor skill dependency increases
Solution Approach 1:
The web portion and deck portion are integrally formed as a single unit, eliminating the need for separate fastening operations between these components. This merging reduces assembly time and simplifies the fastening process while maintaining structural integrity.
Solution Approach 2:
The integrated joist system provides multiple functions within a single component: structural support, lateral bracing, and deck attachment. The universal design reduces the number of separate fastening means required while achieving multiple structural objectives simultaneously.
2Stability of the object's composition
If traditional joist systems require lateral bracing to resist twisting, then structural stability is improved, but device complexity and assembly time increase
Solution Approach 1:
The lateral bracing function is merged into the integral connection between web and deck portions. The monolithic structure provides inherent resistance to twisting and lateral forces without requiring separate bridging components, thereby maintaining stability while reducing complexity.
3Strength
If joists are manufactured from heavy materials like steel, then structural strength is improved, but ease of assembly and handling deteriorate
Solution Approach 1:
The joist system utilizes composite construction with the integral web and deck portions formed from compatible materials that provide high strength-to-weight ratio. This allows the joists to maintain structural strength while being lighter and easier to handle and assemble.
4Reliability
If multiple fastening means are used to secure sub-floor to joist, then structural reliability is improved, but assembly time and labor dependency increase
Solution Approach 1:
The integral formation of web and deck portions eliminates the need for multiple separate fastening operations. The unified structure provides inherent structural reliability while significantly reducing assembly time and labor requirements compared to systems requiring multiple discrete fastening steps.

AI summary
A deck assembly uses plurality of joists preferably formed from metal located side by side and each having a web portion and a deck portion integrally formed with the web portion. The deck portion extends laterally from the web portion and the joists are spaced from one another such that the deck portions from a continuous deck surface with the joists being connected to one another.
