Building Wall Connection Modules for Shear and Thermal Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall connection systems between building walls and floor or ceiling slabs inadequately absorb shear forces and fail to decouple deformation and force transmission, leading to uneven force distribution and potential wall expansion issues.
Innovation Solution
The use of molded blocks with distinct fixed and plain bearing modules, where fixed bearing modules absorb and transmit shear forces and maintain wall stability, while plain bearing modules allow longitudinal movement to compensate for thermal expansion, thereby distributing shear forces effectively and maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If identical connection elements are used throughout the wall, then manufacturing is simplified, but force distribution becomes uneven and wall expansion is restricted
Solution Approach 1:
The connection elements are segmented into two distinct types: fixed bearing modules and sliding bearing modules. This segmentation allows each module to perform a specific function - fixed modules provide stable force transmission while sliding modules accommodate thermal expansion. The wall connection system is divided into zones with different module types, creating a heterogeneous structure that improves both manufacturing clarity and structural reliability.
Solution Approach 2:
Different connection modules are assigned to different locations along the wall based on local requirements. Fixed bearing modules are placed where stable force transmission is needed, while sliding bearing modules are positioned where thermal expansion accommodation is critical. This local differentiation optimizes the performance of each section of the wall connection system.
2Force
If fixed bearing modules are used throughout, then force transmission is maximized, but wall movement due to thermal expansion is restricted
Solution Approach 1:
The connection system incorporates dynamic elements through sliding bearing modules that can move relative to the wall and floor/ceiling slab. This dynamic capability allows the system to adapt to thermal expansion while fixed bearing modules maintain force transmission. The combination creates a semi-dynamic system that balances stability and adaptability.
Solution Approach 2:
Sliding bearing modules act as intermediaries between the fixed bearing modules and the wall structure. These intermediate elements absorb the thermal expansion movements and prevent them from being transmitted to the fixed modules, thereby protecting the overall structure while maintaining force transmission capability through the fixed modules.
3Adaptability or versatility
If sliding bearing modules are used throughout, then thermal expansion is accommodated, but shear force transmission is insufficient
Solution Approach 1:
The connection system is segmented into fixed bearing modules for shear force transmission and sliding bearing modules for thermal expansion accommodation. This segmentation ensures that each function is performed by the appropriate module type, preventing the compromise that would occur if sliding modules were used throughout.
4Temperature
If compression elements are spaced at intervals in the insulating body, then thermal insulation is improved, but shear force transmission capability is limited
Solution Approach 1:
The connection system separates the compression elements into discrete modules (fixed and sliding bearing modules) that are spaced at intervals within the insulating body. This segmentation maintains thermal insulation by leaving gaps filled with insulating material while each module independently provides shear force transmission capability.
Solution Approach 2:
The connection system uses composite construction with bearing modules made of load-bearing materials (such as concrete or steel) embedded in an insulating material matrix. This composite structure allows the system to simultaneously achieve thermal insulation from the insulating material and shear force transmission from the bearing modules.
