Facade Bracket Spring Tongue Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting brackets for facade systems face challenges in simplifying assembly, ensuring dimensional stability for heavy loads, and fulfilling both structural and design requirements, particularly when dealing with thick thermal insulation layers and heavy cladding materials like natural stone or glass.
Innovation Solution
A mounting bracket with a first leg for substrate attachment and a second leg featuring a spring tongue and a tab that forms a stop for precise positioning of holding profiles, along with a lug for guiding and clamping, is designed to simplify assembly and enhance dimensional stability. The bracket is manufactured from stainless steel to handle heavy loads and reduce thermal conductivity, allowing for thicker insulation layers and varied overhangs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the distance between the panel-shaped wall or ceiling cladding elements and the load-bearing structure increases to accommodate thick thermal insulation layers, then thermal insulation performance is improved, but the structural load and bending stress on the bracket increase
Solution Approach 1:
The bracket is divided into multiple functional parts: a first leg for substrate attachment, a second leg for holding profile attachment, and an integrally formed spring tongue for clamping. This segmentation allows each part to be optimized for its specific function, distributing the load effectively and enabling the bracket to span greater distances while maintaining strength.
Solution Approach 2:
The bracket is made from spring steel material, changing the material parameter to provide high elasticity and load-bearing capacity. This allows the bracket to maintain dimensional stability and resist bending stress even when spanning thick thermal insulation layers (10-20 cm), thus improving thermal insulation performance without sacrificing structural strength.
2Reliability
If a separate clamping tongue is used to fasten the support rail to the bracket, then the support rail can be securely attached, but the assembly process becomes more complex and requires additional work steps
Solution Approach 1:
The spring tongue is integrally formed with the second leg of the bracket as a single piece, eliminating the need for separate clamping tongue components and their associated attachment steps. This merging maintains secure fastening of the support rail while significantly simplifying the assembly process and reducing the number of parts.
Solution Approach 2:
The spring tongue serves multiple functions: it acts as a clamping element to secure the support rail, provides elastic compensation for positioning tolerances, and integrates with the second leg to form a unified fastening structure. This multi-functionality reduces overall device complexity while maintaining fastening reliability.
3Adaptability or versatility
If the bracket is designed to hold heavy facade elements like natural stone or glass, then the facade system can use premium materials, but the dimensional stability requirements and structural demands on the bracket increase
Solution Approach 1:
The bracket is made from spring steel material with optimized mechanical properties, changing the material parameters to provide high strength-to-weight ratio and exceptional dimensional stability. This enables the bracket to support heavy premium materials like natural stone and glass while maintaining its own dimensional stability under load.
Solution Approach 2:
The bracket structure is segmented into optimized zones: the first leg for stable substrate connection, the second leg for support rail attachment, and the spring tongue for elastic clamping. This segmentation allows each zone to be optimized for its specific mechanical demands, enabling the overall structure to maintain dimensional stability when supporting heavy facade materials.
