Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for in situ production of sandwich walls with concrete walls separated by a thermal insulation panel face challenges such as lifting of the insulating panel during concrete pouring and difficulty in maintaining and adjusting structural reinforcement for enhanced mechanical strength.
Innovation Solution
A tooling system comprising a positioning system with a dagger and lock mechanism, allowing for the adjustment and securement of reinforcement relative to the insulating panel, ensuring it remains in place during concrete pouring, and adaptable to various reinforcement sizes and positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If positioning systems with rods passing through the insulating panel are used to hold the panel during concrete pouring, then the insulating panel is maintained in position, but the reinforcement cannot be held in position or adjusted beforehand
Solution Approach 1:
The positioning system is designed to perform multiple functions: it positions the insulating panel during concrete pouring and simultaneously holds the reinforcement in position. The rod passing through the insulating panel includes features that can engage with both the panel and the reinforcement, making the system versatile for integrating both components without requiring separate positioning mechanisms.
Solution Approach 2:
The function of positioning the insulating panel and holding the reinforcement is merged into a single integrated positioning system. The rod that passes through the insulating panel also incorporates elements to secure the reinforcement, combining what were previously separate functions into one unified device that addresses both requirements simultaneously.
2Reliability
If assembly devices are arranged outside the wall to hold formwork in position, then the formwork is maintained during pouring, but the devices must be removed after concrete solidifies while positioning systems remain trapped in the wall
Solution Approach 1:
The positioning system is divided into two distinct parts with different fates: assembly devices that are removed after concrete solidification and positioning systems that remain trapped in the wall. The assembly devices include features for easy removal after serving their purpose, while the positioning systems are designed to be retained within the concrete structure, eliminating the need to remove all components.
Solution Approach 2:
The assembly devices are designed to be discarded after their temporary function of holding formwork during pouring is complete, while the positioning systems are recovered and retained within the concrete structure to serve as embedded anchors or positioning elements for the finished wall assembly.
3Shape
If a stop assembly is used between the insulating panel and reinforcement, then the components are separated, but effective maintenance of the reinforcement is not allowed
Solution Approach 1:
The positioning system provides dynamic adjustment capability for the reinforcement position. The rod passing through the insulating panel includes adjustable features that allow the reinforcement to be positioned at different locations along the rod length, enabling both initial positioning and subsequent maintenance or adjustment of the reinforcement position as needed.
Solution Approach 2:
The rod serving as the positioning system acts as an intermediary between the insulating panel and the reinforcement. It maintains separation between these components while providing a mechanism for positioning and maintaining the reinforcement, eliminating the need for a rigid stop assembly that would prevent adjustment or maintenance.
4Manufacturing precision
If positioning systems are designed to hold specific reinforcement sizes, then precise positioning is achieved, but the system cannot adapt to reinforcements of varied sizes
Solution Approach 1:
The positioning system is designed with universal features that allow it to accommodate reinforcements of various sizes while maintaining precise positioning. The rod and associated components can engage with different reinforcement dimensions through adjustable or scalable engagement features, making the system versatile for different reinforcement specifications without sacrificing positioning accuracy.

AI summary
The invention relates to a tool for the construction of a wall (1) with two concrete wall sections (2, 3), between which at least one insulating panel (4) is entrapped. This tool comprises at least one system (8) for positioning the insulating panel (4) that is composed, on the one hand, of a dagger (10) having a stem (12) provided with a bearing stop (13) and, on the other hand, of a lock (11) provided with a counter-stop (16). The lock is provided with at least two notches (17) for receiving a first reinforcement (51), said notches being arranged locally on the circumference of the positioning system, extending set back from the first end of the stem, being delimited on either side by retaining stops spaced apart so as to retain the first reinforcement (51) in position, defining a housing with a profile converging in an opposite direction to their opening, and arranged along the length of the positioning system (8) so as to be able to adjust the position of the first reinforcement (51) along the length of the positioning system (8).
