Embeddable Corbel Mount Layout for Heavy Beam Load Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corbel systems face issues with supporting heavy concrete beams, as the weight generates tensile and shear stresses and torque, causing the mount to bow outward due to inadequate anchoring and distribution of forces.
Innovation Solution
A mount with a plate featuring keyhole slots and a plurality of anchors, including a fifth anchor positioned within a convex quadrilateral defined by four peripheral anchors, enhances pull-out strength and load-bearing capacity by distributing forces effectively, thereby preventing distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If four peripheral anchors are used in the mount plate, then the structure is simple and easy to manufacture, but the load-bearing capacity is insufficient and the mount bows outward under heavy beam loads
Solution Approach 1:
The mounting plate is divided into multiple anchor points (five anchors instead of four), with the fifth anchor positioned at the center to segment the load distribution. This segmentation allows the mount to better resist torque and prevent bowing under heavy loads, directly resolving the strength deficiency of the four-anchor configuration.
Solution Approach 2:
The invention combines peripheral anchors with a central anchor to create a unified mounting system. The fifth central anchor merges with the four peripheral anchors to form a convex quadrilateral pattern that optimally distributes tensile and shear stresses, thereby increasing overall load-bearing capacity without creating redundant components.
2Stability of the object's composition
If anchors are positioned only at the periphery of the plate, then the manufacturing process is simple, but the force distribution is inadequate and torque causes plate distortion
Solution Approach 1:
The mounting plate transitions from uniform peripheral anchoring to non-uniform anchoring with a central fifth anchor. This local quality change concentrates anchoring strength where torque and tensile stresses are most severe, optimizing resistance to plate bowing and distortion while maintaining manufacturing simplicity.
Solution Approach 2:
The anchor configuration changes from symmetric peripheral-only placement to an asymmetric pattern including a central anchor within the convex quadrilateral. This asymmetric positioning better counteracts the asymmetric torque and shear forces generated by heavy beam loads, preventing plate distortion.

AI summary
A concrete embeddable mount for a ledge is provided having a plate with a plurality of keyhole slots therein, four anchors extending from the back of the plate, for embedding the mount in a precast concrete component, wherein the anchors define vertices of a convex quadrilateral, and a fifth anchor extending from the back of the plate, wherein the fifth anchor is positioned within the convex quadrilateral defined by the four anchors. The invention further includes a ledge having a back plate and a perpendicular base extending from the back plate, wherein the back plate has a plurality of rearward extending studs aligned to engage the keyhole slots in the mount plate. Together, the mount and the ledge create a corbel system.
