Concrete Wall Stabilizing Bracket and Aggregate Composite
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for stabilizing concrete basement walls against inward movement due to external forces, such as soil pressure, often require manual adjustment and do not effectively resist shear forces, leading to structural integrity issues and water infiltration.
Innovation Solution
A V-shaped support bracket with legs fastened to a floor joist and a plate extending into the concrete wall, along with an aggregate composite filled into wall voids, to resist inward forces and prevent movement, while allowing water to flow through.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wall reinforcement methods are used, then structural support is provided, but manual adjustment is required and forces are not maintained when soil contracts
Solution Approach 1:
The device uses a spring mechanism that automatically adjusts and maintains force against the wall without requiring manual intervention. The spring expands and contracts self-adjustingly in response to wall movement and soil pressure changes, eliminating the need for periodic manual tightening or adjustment.
Solution Approach 2:
The reinforcement system transitions from a static structure to a dynamic one where the spring continuously adapts its force output. The spring mechanism provides variable force that automatically responds to changing conditions such as soil contraction or expansion, maintaining optimal pressure against the wall throughout seasonal and environmental changes.
2Strength
If conventional reinforcement methods are used, then wall support is provided, but shear forces at the base are not effectively resisted
Solution Approach 1:
The device adds a vertical dimension to wall reinforcement by extending a leg down to the wall base and providing downward force. This creates a moment arm that generates both horizontal support force and vertical downward pressure at the base, effectively resisting shear forces that conventional horizontal-only reinforcement cannot address.
Solution Approach 2:
The downward-extending leg pre-positions force application at the wall base where shear forces are most critical. By establishing this force path in advance through the spring mechanism's continuous pressure, the system proactively prevents shear failure before it occurs rather than reacting to damage after it happens.
3Strength
If solid concrete filling is used in wall voids, then structural strength is increased, but water infiltration is not prevented
Solution Approach 1:
The invention replaces solid concrete filling with a porous aggregate composite material that maintains structural strength while allowing water to flow through it. The porous structure provides mechanical support to the wall blocks while simultaneously enabling water to pass through the voids without causing hydrostatic pressure buildup or infiltration damage.
Solution Approach 2:
The system converts the previously harmful effect of water accumulation in voids into a beneficial drainage function. By filling voids with permeable aggregate rather than solid concrete, the design allows water to flow through the wall structure harmlessly, transforming the voids from potential failure points into active drainage pathways that protect the wall.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides sustained resistance to inward forces, reduces manual adjustment needs, and enhances structural integrity by increasing friction and shear resistance, while maintaining water permeability.
Implementation Method 1
increases the friction that resists inward movement of the joist
Implementation Method 2
an aggregate composite is deposited within voids conventionally formed in at least about the lowest two courses of blocks
Implementation Method 3
The aggregate composite is highly water-permeable, thereby allowing water to flow through the composite
Implementation Method 4
allowing water to flow through and downwardly out of the wall
Implementation Method 5
the support bracket, and, thereby, the joist is forced horizontally away from the wall
Implementation Method 6
the moment arm causes a rotational force to be applied to the joist

AI summary
Concrete wall supports that reduce or eliminate wall movement due to exterior horizontal forces. One support is a bracket mounted to a floor joist with a plate extending below the top of the wall and two legs extending from the plate and attaching to the joist. One leg is above the concrete wall on one horizontal side of the plate, and the other leg is on the opposite side of the plate. Another support has a plate that extends below the top of the wall with two legs on opposite sides of the joist above the wall. A leg attaches to the lower edge of the joist. A support against shear forces includes a highly water permeable aggregate composite disposed in the voids of the wall, with a supportive strip that is enclosed in the aggregate composite and extends out of the voids to the face of the wall.
