Insulated Ventilated Wall Structure Without Panel Perforation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulated wall construction techniques suffer from thermal and acoustic bridges due to the need for longitudinal profiles that perforate insulating panels, leading to increased construction time, cost, and vulnerability to atmospheric agents, and require complex installation steps.
Innovation Solution
A ventilated wall structure with spacer elements that directly attach to both load-bearing longitudinal profiles and wall supports, eliminating the need for longitudinal load distribution profiles, thereby maintaining panel integrity and reducing thermal and acoustic bridges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If longitudinal profiles are embedded in insulating panels to support brackets, then the wall structure can support finishing panels, but thermal and acoustic bridges are created and panel integrity is compromised
Solution Approach 1:
The patent introduces an intermediary bracket element that transfers loads from finishing panels to the wall support structure without requiring longitudinal profiles to penetrate the insulating panels. The bracket acts as a mediator between the cladding system and the wall, distributing mechanical loads to the support structure while leaving the insulation layer intact and continuous.
2Ease of operation
If longitudinal profiles are inserted into insulating panels, then brackets can be supported, but construction time and cost increase due to complex installation steps
Solution Approach 1:
The patent segments the load-bearing function from the insulating function by using separate components: the wall support structure provides mechanical support through brackets, while the insulating panels remain as continuous, unperforated elements. This segmentation allows each component to be optimized independently and installed more efficiently without the complexity of integrating longitudinal profiles into the panels.
3Strength
If insulating panels are hollowed out to join profiles, then the wall structure gains load-bearing capability, but thermal and acoustic bridges increase and insulation performance deteriorates
Solution Approach 1:
The patent extracts the load-bearing function from the insulating panels by removing the need for longitudinal profiles to be embedded in them. The support function is taken out and assigned to a separate wall support structure with brackets, allowing the insulating panels to remain intact and continuous, thereby eliminating thermal and acoustic bridges that would otherwise be created by perforations.
4Adaptability or versatility
If longitudinal profiles are used to support brackets, then the ventilated wall structure can be realised, but the surface continuity of insulating panels is interrupted and panel durability is reduced
Solution Approach 1:
The bracket serves as an intermediary element that enables the ventilated wall configuration without compromising panel integrity. It transfers the mechanical loads and structural requirements to the wall support system, allowing the insulating panels to maintain their continuous surface and structural integrity throughout their service life.
