Insulating Wall Crimped Hoisting Slings

Solution Overview

Problem

The existing manufacturing process for insulating walls with permanent formwork is inefficient due to the need to transport and store heavy structural reinforcements and connection means at remote stations, complicating the installation of insulating panels and increasing the difficulty of handling these components.

Innovation Solution

The process involves embedding connection means with slings in separate skins of the insulating wall, allowing for secure fastening and facilitating the connection to a handling machine, which can be done within the traditional production line or after removal, eliminating the need for remote installation and storage of structural reinforcements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If structural reinforcement and connection means are made and stored near the production line or fed via traditional conveying means, then the installation station can be located remote from the production line, but this constitutes a tedious task due to the weight and dimensions of the structural reinforcement and increases handling complexity

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the structural reinforcement with the formwork elements (skins) by integrating connection means directly into the formwork structure. The connection means are embedded in the concrete skins during casting, eliminating the need for separate handling and installation of structural reinforcements at remote stations. This integration resolves the contradiction by making the structure itself part of the formwork, thereby easing operation while reducing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connection means are prepared and positioned in advance during the concrete casting process. The slings and fastening means are installed in the formwork before concrete is poured, so that when the wall is completed, the connection means are already in place and ready for use. This preliminary action eliminates the need for subsequent handling and installation operations at remote stations.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If connection means are embedded in separate skins and fastened together with crimped slings, then secure connection between skins is achieved, but the manufacturing process becomes more complex

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The connection means utilize the concrete skins themselves as part of the fastening mechanism. The slings are embedded in the concrete and the concrete structure provides the anchoring function, eliminating the need for separate anchoring components. This self-service approach maintains reliable connection strength while simplifying the manufacturing process by reducing the number of distinct components that must be manufactured and assembled.

Inventive Principle:
Principle #25Self-service

3Productivity

If the manufacturing process uses traditional production line for conventional walls, then existing infrastructure can be utilized, but the process cannot accommodate insulating panels and requires additional remote installation steps

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The formwork system is designed to perform multiple functions: it serves as the mold for casting concrete skins, provides structural support during casting, and incorporates the connection means for assembling insulating walls. The skins themselves become both the formwork and the structural component of the final wall, eliminating the need for separate formwork removal and additional installation steps.

Inventive Principle:
Principle #6Universality (Multi-functionality)
