Pivotable Mobile Connecting Element for Integral Formwork Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing walls with integrated formwork face challenges in connecting two juxtaposed walls due to hindrances from connecting means, requiring specific tools and manual effort, and are limited to non-seismic zones, with potential for junction defects and loss of connecting devices.
Innovation Solution
A wall with integrated formwork featuring a movable element that rotates between retracted and deployed positions, allowing for easy connection and disconnection without the need for specific tools or openings, and enabling use in seismic zones by integrating the mobile element with the connecting means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile element is engaged in the internal volume of two juxtaposed walls to connect them, then the connection between walls is achieved, but the progression of the mobile element is hindered by the connecting means between the skins
Solution Approach 1:
The mobile element is designed to rotate between a retracted position (where it is contained within the wall's internal volume) and a deployed position (where it extends outward to connect with the adjacent wall). This dynamic transformation allows the mobile element to navigate around the connecting means during rotation, resolving the contradiction between achieving reliable connection and maintaining ease of operation.
2Ease of operation
If openings are provided in the wall to allow displacement of the mobile armature, then the mobile element can be positioned, but the wall requires subsequent sealing intervention and the displacement may be hampered by connecting means
Solution Approach 1:
The mobile element is pre-mounted on the connecting means in a retracted position during wall assembly. This preliminary positioning eliminates the need for subsequent openings and sealing operations, as the mobile element is already in place and can simply be rotated to its deployed position to connect with the adjacent wall.
3Reliability
If a staple device is used to connect two forms, then the junction between forms is achieved, but the device requires adjusted dimensioning, precise positioning, and considerable manual effort
Solution Approach 1:
The mobile element rotates into place to connect the two walls, eliminating the need for precise manual positioning and considerable effort required by staple devices. The rotational movement allows the mobile element to self-align and connect reliably without adjusted dimensioning or complex positioning procedures.
4Ease of manufacture
If a staple is hung on a means for connecting, then the connection is achieved, but a simple handling error can lead to detachment and loss of the staple
Solution Approach 1:
The mobile element is integrated with the connecting means through a rigid or fixed connection, eliminating the simple hanging arrangement of staples. This merging ensures that the mobile element cannot detach due to handling errors, while still allowing for reliable installation during wall assembly.
5Adaptability or versatility
If the mobile element is designed to extend laterally outside the wall in the deployed position, then the connection to adjacent wall is enabled, but the element occupies space within the internal volume when retracted
Solution Approach 1:
The mobile element dynamically transitions between a retracted position (contained within the wall's internal volume) and a deployed position (extending laterally to connect with the adjacent wall). This dynamic behavior allows the element to minimize space occupation during storage and transport while enabling full connection capability during operation.

AI summary
The wall (1) has a metallic movable element (6) movable between retracted and deployed positions. The element has a first portion extending inside an internal volume (4) of the wall, and a second portion that extends laterally and externally relative to the wall in deployed position of the element. The second portion extends partially inside another internal volume of the wall in the retracted position of the element. A mounting unit rotatably mounts the element on a connecting unit (5) i.e. U-shaped fastener, connecting skins (2, 3) of the wall, between the positions of the element. The movable element is chosen from a group comprising a rod, a bar, a U-shaped part and a frame.
