Facade Insulation Mounting Rail System with Tension Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction industry faces challenges in efficiently and cost-effectively fastening thermal insulation panels to building exteriors due to increasing weight and density requirements, which lead to higher costs and installation complexities, as existing solutions are either unsuitable for lighter panels or inadequate for supporting heavier ones.
Innovation Solution
A facade insulation system that uses a combination of thermal insulation panels with different densities and a mounting rail system with spacers and tension brackets to securely attach panels to the building wall, allowing for flexible adaptation to insulation needs and minimizing weight while maintaining effective thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If thermal insulation panels are made thicker to improve energy saving, then thermal insulation performance is improved, but weight increases
Solution Approach 1:
The thermal insulation system is divided into multiple panels that can be assembled together. Each panel maintains optimal thickness for insulation performance while the modular design allows achieving total insulation requirements through combination, controlling individual panel weights
Solution Approach 2:
The system uses composite construction with thermal insulation panels combined with a mounting rail system. The rails provide structural support to distribute loads, enabling use of lighter insulation materials that would otherwise be insufficient for the required insulation thickness
2Strength
If thermal insulation panels are made denser to enable direct plastering, then surface strength is improved, but weight increases
Solution Approach 1:
The mounting rails provide localized structural support at specific points (mounting locations) rather than requiring the entire panel to be dense. The rails bear the mechanical loads, allowing the insulation panel material itself to be lighter while still providing adequate surface for plastering
3Reliability
If more dowels are used to fasten heavier thermal insulation boards, then fastening reliability is improved, but cost and installation effort increase
Solution Approach 1:
Mounting rails serve as intermediary elements between the thermal insulation panels and the building wall. The rails concentrate fastening points and provide a rigid framework that distributes panel weights, reducing the number of dowels needed compared to direct panel-to-wall fastening
Solution Approach 2:
The mounting rails extend in the spatial dimension perpendicular to the wall surface, creating a three-dimensional mounting structure. This allows panels to be supported at multiple points along the rail length, improving fastening efficiency with fewer dowels per panel
