Pivotable Guide Shoe for Self-Climbing Scaffold System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction systems for multi-storey buildings face inefficiencies in raising scaffolding units, particularly due to the need for additional vertical profiles and crane assistance, which increases complexity and cost.
Innovation Solution
A self-climbing system with a guide shoe that features pivotable guide jaws and rotatable mounting on wall shoes, allowing direct attachment of lifting drives to building brackets, reducing the need for additional profiles and enabling efficient lifting and repositioning of scaffolding units without external cranes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If additional vertical profiles and crane assistance are used to raise scaffolding units, then the scaffolding units can be raised to higher levels, but the system complexity and construction cost increase
Solution Approach 1:
The guide shoe enables the scaffolding unit to raise itself by engaging with brackets on the building structure. The lifting drive, integrated with the guide shoe, allows the scaffolding unit to climb vertically without requiring external crane assistance, thereby reducing system complexity while achieving greater heights
Solution Approach 2:
The guide shoe features a rotatable mounting on the wall shoe, allowing it to adapt its orientation dynamically. The guide jaws can pivot to engage with brackets at different positions and angles on the building structure, enabling flexible climbing motion without rigid structural constraints
2Length of moving object
If additional vertical profiles and brackets are used to support the climbing system, then the scaffolding unit can be raised higher, but the number of required components and installation complexity increase
Solution Approach 1:
The guide shoe serves multiple functions: it provides structural support for the lifting drive, engages with building brackets to enable vertical climbing, and allows rotational adaptation to different bracket positions. This multi-functionality eliminates the need for separate vertical profiles and reduces the total number of components required
Solution Approach 2:
The guide shoe combines the lifting mechanism, guiding function, and structural support into a single integrated component. By merging these functions, the system eliminates the need for additional vertical profiles and reduces the quantity of separate brackets and support elements required
3Stability of the object's composition
If the guide jaw is rigidly attached to the guide shoe, then the structure is more stable, but point loads and stress concentrations occur at attachment points
Solution Approach 1:
The guide jaw is pivotably attached to the guide shoe, allowing it to rotate and adapt to the orientation of the building brackets. This dynamic attachment distributes loads along the pivot axis rather than concentrating them at fixed points, maintaining structural stability while reducing stress concentrations

AI summary
A guide shoe (16) for a climbing system for use in the building sector comprises at least one guide shoe (86) which can be displaced in the horizontal direction and can be pivoted about a horizontal axis. A climbing system comprises: at least one such guide shoe; at least one scaffold unit which can be guided and/or suspended in at least one guide (16) on a structure; and at least one lifting drive which can be releasably fitted directly on discrete mounts (20) on the structure and which can be switched between a first operating mode in which the scaffold unit can be raised and a second operating mode in which the lifting drive can be raised.
