Floor Member Retention Assembly for Wind Uplift Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed winds can lift paving slabs due to reduced static pressure, causing them to move upwards and become dislodged, especially in exposed conditions like balconies or terraces.
Innovation Solution
A floor member retention apparatus with a support surface and retention assembly that includes a tension member forming a tensile load path to secure the slabs, using threaded connections and adjustable components to prevent uplift.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If floor members are left unsupported to maintain simplicity, then device complexity is reduced, but wind lift causes them to move and dislodge
Solution Approach 1:
The retention apparatus is divided into separate functional components: a retention member engaged with the floor member, a tension member forming a load path, and a support structure. This segmentation allows each component to perform its specific function while maintaining overall system reliability without excessive complexity.
Solution Approach 2:
The retention member is pre-configured to engage with the floor member before wind lift can occur. The tension member is pre-installed to establish a load path that will actively resist uplift forces, preventing the floor member from moving in the first place rather than reacting after movement begins.
2Reliability
If retention members are added to prevent wind lift, then floor member stability is improved, but device complexity increases
Solution Approach 1:
The retention member serves multiple functions: it engages with the floor member to prevent movement, provides a attachment point for the tension member, and distributes retention forces. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while maintaining reliable retention.
Solution Approach 2:
The tension member acts as an intermediary element between the retention member and the support structure, creating a clear load path that transfers wind lift forces away from the floor member. This intermediary approach simplifies the overall retention mechanism by using a straightforward tensile force transmission rather than complex mechanical linkages.
3Adaptability or versatility
If tension members with threaded connections are used to adjust load paths, then adaptability is improved, but ease of manufacture decreases
Solution Approach 1:
The threaded connection in the tension member provides dynamic adjustability, allowing the load path to be modified by rotating the tension member axially. This dynamic adjustment capability enables adaptation to different loading conditions and floor member positions while using a standard threaded fastening mechanism that remains relatively simple to manufacture.
Solution Approach 2:
The axial position of the tension member can be changed by rotating it within the threaded connection, thereby adjusting the length and tension characteristics of the load path. This parameter change mechanism provides versatility in adapting to different structural configurations without requiring multiple custom-designed components.

AI summary
An exemplary embodiment of a floor member retention apparatus may include a floor member support for supporting a floor member, the floor member support includes a support surface. The floor retention member may further include a floor member being supported on the support surface of the floor member and a retention assembly including a retention member engaged with the floor member and a tension member configured to form a tensile load path between the retention member and the floor member support to restrict movement of the floor member away from the floor member support.
