Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing keder roof systems face challenges in seamlessly integrating with standard scaffolding systems, leading to gaps and increased assembly complexity, limiting span size and load-bearing capacity.
Innovation Solution
A rigid corner construction with diagonal elements and connecting components that align with standard scaffolding dimensions, allowing seamless integration and assembly without gaps, using components like keder rail profiles and adapters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a corner construction with two perpendicular side rails and two perpendicular end rails is used, then the support structure achieves high stability and rigidity, but the complexity of the support structure increases
Solution Approach 1:
The patent combines the corner construction with the keder profile into a single integrated component. The corner construction is inserted into the recess of the keder profile, merging what would have been separate structural elements into one unified piece, thereby reducing overall structural complexity while maintaining stability.
Solution Approach 2:
The corner construction is nested within the recess of the keder profile. The vertical side rail and horizontal end rail form an L-shaped structure that fits into the corner recess, with the keder covering portion extending over the rails. This nesting arrangement consolidates multiple structural functions into a compact integrated form.
2Adaptability or versatility
If the keder roof hall is disassembled for transport, then the structure becomes more transportable, but the keder profile may become damaged during disassembly and assembly
Solution Approach 1:
The corner construction is pre-assembled as an integrated unit with the keder profile before installation. The vertical side rail, horizontal end rail, and keder covering portion are already connected in the correct configuration, eliminating the need for complex field assembly and reducing the risk of damage during disassembly and reassembly operations.
Solution Approach 2:
By merging the corner construction with the keder profile into a single integrated component, the patent reduces the number of separate parts that need to be handled during disassembly and assembly. This integration minimizes handling operations and potential damage points, thereby improving reliability during transport cycles.

AI summary
The invention relates to a flexurally rigid corner construction (10) for the support structure of a Keder roof hall for the connection of a roof lattice beam (60) in the lattice beam direction and for the connection of a system scaffolding (50.1) in the scaffolding or wall direction with a first truss field (12) extending in the scaffolding direction and a second truss field (14) extending in the lattice beam direction. The invention is characterized in that the second truss field (14) comprises an outer chord element (14.1) with a Keder profile and an inner chord element (14.2), and in that the distance of the outer chord element (14.1) and the inner chord element (14.2) corresponds to the distance of the top chord (60.1) with the Keder rail and the lower chord (60.2) of the roof lattice beam (60), and in that the first truss field (12) has two connecting elements (25.1, 25.2) on the lower side, the system distance of which corresponds to the specific width (SB) of a system scaffolding (50.1), in particular a Layher Allround Scaffolding system or a Layher SpeedyScaf system, or to a track rail construction.
