Center Beam Connection Assembly for Excavation Shoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large excavation sites face challenges with existing shoring systems due to the high cost and inefficiency of materials required for adequate support against cave-ins, as traditional methods like sheet piling are expensive and require extensive material usage.
Innovation Solution
A center beam connection assembly that securely connects a removable center shoring beam to main I-beams using end-caps, reinforcing bars, and spacer bars with hooks and apertures, allowing for temporary, reusable, and additional reinforcement in large excavation sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sheet piling is driven extremely deeply into the ground to provide sufficient support against cave-ins, then the shoring system provides adequate safety and support, but the cost and quantity of material required becomes extremely expensive
Solution Approach 1:
The shoring system is divided into modular components: corner connections, main I-beams, and removable center beams that can be independently configured. This segmentation allows the system to provide adequate support with less total material by optimizing the placement and function of each component rather than using uniform deep sheet piling throughout.
Solution Approach 2:
The center beam is designed to be removable and reusable. After the excavation work is completed, the center beam can be removed and reused in future projects, reducing the need for continuous material consumption and lowering overall project costs while maintaining safety during the excavation period.
2Reliability
If traditional sheet piling methods are used to shore up excavation walls, then adequate protection against cave-ins is provided, but the system is not cost-effective for large excavation sites
Solution Approach 1:
The shoring system transitions from a static, permanent sheet piling structure to a dynamic, adaptable system where center beams can be added or removed based on the specific needs of the excavation site and project timeline, allowing for cost-effective deployment on large sites.
Solution Approach 2:
The system allows changing the configuration parameters of the shoring structure by adding removable center beams between corner connections, enabling the same basic framework to adapt to different site conditions and scale requirements without proportionally increasing material costs.
3Ease of repair
If a removable center beam system is added to existing shoring systems, then reusability and cost-effectiveness are improved, but the device complexity increases
Solution Approach 1:
End caps serve as intermediary components that simplify the connection between the center beam and the existing shoring system. These end caps with integrated connection mechanisms act as mediators, making the overall system easier to assemble and disassemble despite the added complexity of the removable beam component.

AI summary
A center beam connection assembly for temporary shoring includes a pair of end-caps adapted to fit over respective ends of a center shoring beam. Arms extending from each end-cap engage a web of a main shoring beam in a excavation site shoring system. The end-caps may be used alone, or in combination with reinforcing and spacer bars. Reinforcing bars include first and second hooks adapted to connect to a main shoring beam and a center shoring beam, respectively. When utilized, each spacer bar is connected to at least one tab on an end-cap and at least one tab on a reinforcing bar via connecting pins. In this manner, one or more center shoring beams can span an excavation hole to provide removable, reusable and temporary support for a shoring system.
