Frame Wall Connection Using Reinforcing Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame-wall connection arrangements require additional lightweight wall elements for support, which complicates the assembly process and does not provide sufficient stability due to thin cover layers and soft core layers in sandwich panels.
Innovation Solution
A frame-wall connection arrangement featuring a sandwich panel with metal cover layers and an insulating core layer, where a reinforcing profile with a U- or C-shape is used to enhance stability, allowing direct connection to a frame without additional wall elements, using a closing element and fastening means through the reinforcement profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If additional lightweight wall elements are used to provide support for the frame, then the frame gain sufficient stability, but the assembly process becomes more complicated and requires more components
Solution Approach 1:
The patent removes the additional lightweight wall elements (corner frames, counter frames, and associated fasteners) from the assembly process. By directly attaching the frame to the sandwich panel's cover layers, it extracts only the essential components needed for structural stability, eliminating unnecessary intermediate elements and simplifying the overall assembly process.
Solution Approach 2:
The patent merges the frame attachment function directly with the sandwich panel structure. Instead of using separate lightweight wall elements as intermediaries, the frame is directly connected to the cover layers of the sandwich panel, combining the support function with the existing wall structure and reducing the number of discrete components.
2Device complexity
If the sandwich panel is used directly without additional wall elements, then the assembly process is simplified, but the thin cover layers and soft core layer do not provide sufficient support for the frame
Solution Approach 1:
The patent applies local reinforcement by introducing a reinforcing profile at the specific location where the frame attaches to the sandwich panel. This reinforcing profile is positioned locally at the attachment points to provide concentrated support exactly where needed, rather than requiring overall thickening of the entire wall structure. The reinforcing profile creates a localized stiffening effect that enables direct frame attachment while maintaining the thin overall panel design.
3Stability of the object's composition
If the core layer bulk density is increased to improve stability, then the wall part gains more rigidity, but the fire protection properties may be compromised
Solution Approach 1:
The patent optimizes the core layer bulk density parameter to a specific range (60-120 kg/m³, preferably 80-90 kg/m³, particularly 85 kg/m³). This parameter change achieves the right balance between mechanical stability and fire protection performance. The optimized density provides sufficient rigidity for frame attachment while maintaining the insulating properties necessary for fire resistance, avoiding both excessive softness and overly dense construction that could compromise fire safety.

AI summary
The frame-wall connection assembly comprises a frame (2) and a wall section (1) to which the frame (2) is attached. The wall section (1) is a sandwich panel with at least two face layers (1a, 1b) and at least one intermediate core layer (1c). A reinforcing profile (4), preferably U- or C-shaped, encloses the narrow side of the wall section (1), which is preferably covered by a finishing element (3), or at least partially covers it, particularly in the area of the core layer. The frame (2) is arranged on the side of the reinforcing profile (4) facing away from the wall section (1).
