Solution Overview

Problem

Conventional support structures for corner constructions in construction projects face challenges in efficiently connecting and securing beams, leading to complex and potentially unsafe installations, especially when cantilevered or wrapping around corners.

Innovation Solution

A corner beam system with end clips and end caps that facilitate easy connection and secure attachment to other beams, featuring adjustable length, symmetrical design, and multiple attachment points to ensure stability and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional support structures use traditional beam connection methods for corner constructions, then structural strength can be maintained, but the installation complexity increases and safety may be compromised

Engineering Contradiction:

Improveease of installationVSAvoidinstallation complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The corner beam is divided into multiple modular segments that can be easily connected and disconnected. Each segment has standardized connection interfaces that simplify the assembly process, allowing workers to quickly assemble corner structures without complex procedures while maintaining structural integrity through standardized joint designs.

Inventive Principle:

Principle #1Segmentation

2Productivity

If conventional beam connection methods are used, then structural stability can be achieved, but the installation time increases

Engineering Contradiction:

Improveinstallation speedVSAvoidinstallation time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

Connection features such as slots, holes, and attachment points are pre-positioned and pre-configured on the corner beam segments during manufacturing. This preliminary preparation eliminates the need for complex field measurements and adjustments during installation, allowing workers to simply connect the pre-configured elements, thereby significantly reducing installation time while ensuring proper structural alignment.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If traditional corner beam systems are used, then structural support can be provided, but adjustment flexibility for misalignments is limited

Engineering Contradiction:

Improveadjustment flexibilityVSAvoidalignment tolerance

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The corner beam incorporates adjustable connection mechanisms with movable elements such as sliding slots and repositionable attachment points. These dynamic features allow the connection geometry to be adjusted in the field to accommodate misalignments and variations in construction tolerances, providing flexibility without requiring extremely precise manufacturing while still maintaining structural integrity.

AI summary

A corner beam for concrete formwork that connects to other beams (e.g., cantilevered beams) can include various elements. In some examples of this disclosure, the corner beam does not need additional underneath support. In examples, the corner beam simplifies corner constructions and contributes to easier and safer corner formwork installation. For example, the corner beam can include end clips with a post (or other type of hook) that inserts into a pocket of the other beams. In addition, the corner beam can include a trough that extends along the side and that can connect to one or more other supports beams.
