Foam Sheet Settlement Isolation in Building Connection Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial buildings on soft soil layers experience differential settlement between floors and pile foundations or walls due to uneven load distribution, leading to structural cracks and uneven floors, which can disrupt operations.
Innovation Solution
A connection structure using a weight-bearing column, concrete pile foundation, engineering piles, reinforced concrete plates, foam sheets, and cushion layers of plain concrete to absorb and isolate settlement, preventing stress and settlement transmission between floors, walls, and pile foundations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If floors are designed as passageways with natural foundations to save investment, then construction cost is reduced, but differential settlement occurs between floors and pile foundations leading to structural cracks and uneven floors
Solution Approach 1:
The patent introduces foam sheets as intermediary materials placed between the brick wall and concrete pile foundation, between the reinforced concrete plate and building wall, and between adjacent reinforced concrete plates. These foam sheets act as settlement isolation layers that allow differential movement without transmitting stress, preventing structural cracks while maintaining the cost-effective natural foundation design
Solution Approach 2:
The patent segments the connection between the floor structure and pile foundation by inserting foam sheets and cushion layers at multiple interfaces. This segmentation isolates the settlement zones, allowing each component to move independently without causing damage to the overall structure, thus resolving the contradiction between cost savings and structural reliability
2Reliability
If foam sheets and cushion layers are added to block settlement transmission, then structural reliability is improved, but device complexity increases
Solution Approach 1:
The patent uses thin foam sheets as flexible isolation layers between structural components. These thin film-like foam sheets effectively block settlement transmission while adding minimal structural complexity. The foam sheets conform to the interfaces they protect and provide settlement isolation without requiring complex mechanical structures
Solution Approach 2:
The patent changes the physical parameters of the connection interface by introducing compressible foam sheets and cushion layers. These materials change the stiffness and deformation characteristics of the connection, allowing settlement accommodation while maintaining structural integrity. This parameter change approach simplifies the overall connection design compared to rigid mechanical solutions
