Precast Concrete Connection Device with Integrated Load Receptacle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to provide a device and method for precast concrete parts that prevent thermal bridges while ensuring adequate reinforcement, particularly at transitions like balconies to ceilings, without spatial overlap between lifting anchors and thermal connection elements, allowing for efficient handling and lifting of precast concrete elements.
Innovation Solution
A device with a receptacle for a load handling device is integrated into the precast concrete part, allowing the load handling device to be attached despite protruding reinforcement elements, with the receptacle designed to be freely accessible and not overlapping with thermal connection elements, enabling easy handling and lifting while the thermal connection element can also introduce forces from the lifting anchor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transport anchors and thermal connection elements are separately integrated into precast concrete elements, then both lifting capability and thermal insulation are achieved, but spatial overlap occurs between these elements and reinforcement allowances collide
Solution Approach 1:
The patent combines the transport anchor and thermal connection element into a single integrated device. The connecting element serves dual purposes: as a thermal connection element surrounded by insulating material to prevent thermal bridges, and as a transport anchor with a receptacle for lifting devices. This merging eliminates spatial overlap between separate elements and their reinforcement allowances while achieving both lifting capability and thermal insulation functions simultaneously.
2Object-affected harmful factors
If thermal connection elements are integrated into precast concrete parts, then thermal bridges are prevented, but handling and lifting become difficult due to lack of accessible mounting points
Solution Approach 1:
The connecting element is designed with multi-functionality: it provides thermal insulation by being surrounded by insulating material to prevent thermal bridges, and simultaneously provides a mounting function with an accessible receptacle on its outer surface for attaching lifting devices. This allows the same element to fulfill both thermal protection and handling requirements without compromising either function.
3Reliability
If separate transport anchors and thermal connection elements are used, then lifting and thermal insulation functions are achieved, but reinforcement requirements increase due to overlapping reinforcement allowances
Solution Approach 1:
The patent merges the transport anchor and thermal connection element into one integrated device, which eliminates the need for separate reinforcement allowances for each element. The single device requires only one set of reinforcement embedded in the precast concrete, reducing the total quantity of reinforcement material while maintaining both lifting capability and thermal insulation functionality.
