Adjustable Pergola Wall Connection for Uneven Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof construction methods, such as pergolas and conservatories, face challenges in attaching wall connection supports to uneven building walls, requiring complex and costly shimming to ensure proper alignment and aesthetics, as existing solutions are either visible or inefficient.
Innovation Solution
The introduction of a compensating device within the wall connection support allows for adjustable positioning of the retaining rod relative to the holders, enabling the support rod to run in a straight line even when the retaining profile is curved, with holders and a suspension device allowing for linear and pivoting adjustments to accommodate uneven walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the wall connection support is attached directly to an uneven building wall, then the installation is simple, but the alignment and aesthetics deteriorate due to visible shimming and excessive bending
Solution Approach 1:
The wall connection support incorporates an adjustable mechanism that allows the retaining rod to be repositioned dynamically during installation. This enables the support structure to adapt to uneven wall surfaces without requiring complex shimming, thereby maintaining both installation simplicity and alignment precision.
Solution Approach 2:
The position of the retaining rod relative to the holders can be adjusted by changing the mounting parameters of the compensating device. This allows the straightness of the retaining rod to be maintained even when the retaining profile is curved due to wall unevenness, resolving the contradiction between simple installation and precise alignment.
2Manufacturing precision
If shimming is used to compensate for wall unevenness, then alignment precision improves, but device complexity and cost increase
Solution Approach 1:
The compensating device serves multiple functions: it provides alignment adjustment, maintains the straightness of the retaining rod, and accommodates wall unevenness. By integrating these functions into a single mechanism, the overall device complexity is reduced compared to using separate shimming components.
Solution Approach 2:
The adjustable mechanism allows for easy self-adjustment during installation without requiring complex external tools or procedures. The position of the retaining rod can be modified directly through the compensating device, enabling the system to self-correct for wall unevenness.
3Adaptability or versatility
If the retaining profile is curved to match the building wall, then adaptability improves, but the straightness of the retaining rod deteriorates
Solution Approach 1:
The wall connection support is divided into separate functional components: the retaining profile that contacts the curved wall, and the retaining rod that must remain straight. The compensating device acts as an intermediary that decouples these two requirements, allowing the profile to adapt to wall curvature while the rod maintains its straightness through adjustable positioning.

AI summary
A roof structure, particularly in the form of a pergola or glass roof, comprises a wall connection beam and at least one crossbeam, which are spaced apart from each other. Several longitudinal beams, spaced apart from each other, are provided, each bridging the gap between the wall connection beam and the crossbeam, with at least the wall connection beam being attachable to a supporting structure. The wall connection beam has a retaining profile that can be attached to the supporting structure, to which several spaced-apart brackets are attached, and a support rod is mounted. At least one of the longitudinal beams engages with and is supported by the support rod.It is provided that the holders each have a compensating device by means of which the position of the support rod relative to the respective holder can be adjusted at least with one component in the longitudinal direction of the longitudinal beams.
