Prefabricated Structure Rod Anchoring for Uplift Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for relocating or securing prefabricated structures like mobile homes are complex, labor-intensive, and can lead to instability or structural failure due to uneven force distribution, especially under extreme weather conditions, as they often require lifting the entire structure, which can cause damage.
Innovation Solution
A system involving a rod with an attachment point and a brace end is used, where the rod is passed through the structure's walls, with the attachment point extending from either the exterior floor or roof surface, allowing forces to be distributed at the exterior roof or floor surface, thereby preventing structural uplift and damage during relocation or securing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the entire structure is lifted by means of a crane or hydraulic jacks, then the structure can be relocated, but the structure may be damaged due to forces not designed to withstand such lifting
Solution Approach 1:
The invention divides the lifting force application into discrete segments by using multiple individual lifting devices (cranes or hydraulic jacks) positioned at specific locations along the structure. Each device independently supports a portion of the total weight, distributing the mechanical stress across multiple attachment points rather than concentrating it at a single location, thereby preventing structural damage during relocation
Solution Approach 2:
The invention applies local quality by positioning lifting devices at specific locations along the structure where the local structural capacity can best withstand the applied forces. The attachment points are strategically selected to match the structure's structural framework, ensuring that lifting forces are applied at locations with adequate local strength while maintaining overall balance and stability during the relocation process
2Reliability
If cable slings are looped underneath the structure to prevent wall lift-off, then the structure can be safely lifted, but the process becomes more complex and labor-intensive
Solution Approach 1:
The invention inverts the traditional approach by attaching lifting devices to the top or side of the structure rather than looping slings underneath. This reversal simplifies the lifting system by eliminating the need for complex under-structure sling configurations while still achieving reliable force distribution through strategically positioned attachment points that directly connect to the structural framework
3Force
If screw-anchors are used to secure the structure against wind forces, then the structure can be anchored to the ground, but the anchors may be pulled out when large forces are applied
Solution Approach 1:
The invention segments the anchoring system by using multiple individual anchors distributed at various locations around the structure's perimeter rather than relying on a single anchor point. This segmentation distributes the wind-induced forces across multiple anchor points, preventing any single anchor from experiencing forces exceeding its holding capacity and thereby maintaining reliable ground attachment under extreme weather conditions
4Reliability
If multiple anchors are distributed around the structure, then the force can be distributed evenly, but the complexity and labor intensity of the securing process increases
Solution Approach 1:
The invention applies universality by using standardized anchor components and attachment mechanisms that can be repeatedly installed at multiple locations around the structure using the same procedures and equipment. This multi-functional approach allows the same anchoring system design to be universally applied at each perimeter location, achieving even force distribution while maintaining operational simplicity through consistency and repeatability in the installation process

AI summary
The invention pertains to a method and system for moving or securing a mobile or prefabricated structure. The method involves the use of at least one rod having an attachment point and a brace end. The rod is run through the wall, with the attachment point extending from either the exterior roof or floor surface. A brace is coupled to the rod outside the structure, distributing force created by pulling on the attachment end. The attachment point can be coupled to a crane for lifting the structure or to a pile, such as a helical pile, anchored to the ground for securing the structure. A system that may include a prefabricated structure is provided including the rod having an attachment point and a brace. The rod may be a steel rod with a specific diameter and may include a threaded section or an eye hook as the attachment point.
