Precast Concrete Transport Anchor for Lateral Lifting Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport anchor systems for precast concrete parts result in high material loss and are inefficient for flat, thin-walled, and double-walled concrete parts, as they cannot be easily reused and are not suitable for lateral lifting due to deep anchoring, leading to increased handling difficulties and material waste.
Innovation Solution
A transport anchor system with a load-carrying device that can be screwed into the screw channel of the transport anchor, featuring a recess body that allows for precise placement and reuse, minimizing material loss by relocating the anchor point to the outside of the concrete part, enabling lateral lifting and reducing the weight of the transport anchor while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the transport anchor is deeply anchored in the precast concrete element to ensure structural integrity, then the anchoring strength is improved, but the lifting device cannot engage on the outside surface and material loss increases
Solution Approach 1:
The transport anchor system is divided into two separate components: a transport anchor that remains embedded in the concrete element and a load-bearing device that attaches to it. This segmentation allows the anchor to be deeply embedded for strength while the load-bearing device provides external engagement capability, resolving the contradiction between deep anchoring and external accessibility.
Solution Approach 2:
The load-bearing device acts as an intermediary between the embedded transport anchor and the external lifting device. It connects to the screw channel of the anchor internally while providing an external lifting eye or engagement point, enabling both deep anchoring and external lifting capability without compromising either function.
2Reliability
If the transport anchor is deeply embedded to prevent concrete from entering the screw channel, then the screw channel protection is improved, but the lifting device cannot engage on the outside of flat or thin-walled elements
Solution Approach 1:
By separating the transport anchor (embedded for protection) from the load-bearing device (external for engagement), the system maintains screw channel protection while enabling versatility for different element types including flat and thin-walled elements that require external lifting points.
Solution Approach 2:
The solution moves the engagement point from the internal screw channel to an external dimension via the load-bearing device with lifting eye. This dimensional transition allows lifting devices to engage externally even when the anchor is deeply embedded, enabling use with flat and thin-walled elements.
3Loss of substance
If the transport anchor is reused after concrete hardening, then material loss is reduced, but the anchor must be accessible for lifting tool engagement
Solution Approach 1:
The system separates the permanent embedded anchor from the reusable load-bearing device. The load-bearing device can be detached and reused with different anchors, while the anchor remains embedded for future use, optimizing both material utilization and operational flexibility.
Solution Approach 2:
The load-bearing device is designed to be detached and recovered for reuse with subsequent concrete elements, while the embedded transport anchor remains in place for future lifting operations. This selective recovery approach minimizes material loss while maintaining ease of operation.
4Productivity
If the transport anchor system is designed for lateral lifting of flat and thin-walled elements, then handling efficiency is improved, but the anchoring depth and structural integrity may be compromised
Solution Approach 1:
The load-bearing device serves as an intermediary that transfers lifting forces from external engagement points to the embedded transport anchor. This allows lateral lifting configuration for improved handling efficiency while the deep-embedded anchor maintains structural integrity by distributing loads throughout the concrete element.

Function Achieved in This Case
