Insulating Layer Screw Anchor for Facade Substructure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facade substructure systems for attaching cladding elements to building walls are complex to assemble and require visible fastening components, which are not aesthetically pleasing and may compromise the integrity of the insulating layer.
Innovation Solution
A surface cladding substructure unit comprising an insulating layer screw anchor with a support bolt, washer, helical structure, and stiffening section, which allows for secure fastening of cladding elements to both the insulating layer and the substructure, enabling easy assembly and versatile use without visible fastening, using an insulating layer screw anchor that can be manually assembled and adjusted for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-part facade substructures with vertical and horizontal profile supports are used, then the facade elements can be reliably supported, but the assembly process becomes multi-stage and complex
Solution Approach 1:
The patent combines multiple support functions into a single integrated anchor element that simultaneously provides vertical support, horizontal positioning, and secure fastening capabilities, eliminating the need for separate vertical and horizontal profile supports
Solution Approach 2:
The anchor element serves multiple functions: it anchors to the insulating layer, provides a mounting surface for facade elements, enables adjustable positioning, and ensures secure fastening, replacing the need for multiple specialized components
2Reliability
If conventional fastening screws are used to attach components to masonry, then the attachment is secure, but the fastening screw is visible from the outside which is aesthetically displeasing
Solution Approach 1:
The patent extracts the fastening function from visible surface-mounted screws and relocates it to hidden anchor elements embedded within the insulating layer, eliminating visible fastening components while maintaining secure attachment
Solution Approach 2:
The insulating layer serves as an intermediary medium that houses the anchor elements, allowing secure fastening to occur hidden within the insulation rather than requiring visible external fasteners
3Reliability
If conventional facade substructures are used, then facade elements can be attached, but the assembly process requires multiple stages and is time-consuming
Solution Approach 1:
The patent segments the fastening system into a pre-fabricated modular anchor element that can be independently manufactured and then quickly installed as a single unit, eliminating the need for multi-stage assembly of separate profile components
Solution Approach 2:
The anchor elements are pre-assembled with integrated fastening components and positioning features before installation, allowing for rapid deployment during the facade assembly process without requiring multiple construction stages
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies the assembly process, provides stable anchoring, and allows for adjustable ventilation zones, enhancing the structural integrity and thermal separation while avoiding material destruction and thermal bridging, thus ensuring reliable and cost-effective attachment of facade elements.
Implementation Method 1
The helical structure preferably has a coarse structure with great depth in order to ensure a good hold in an insulating material
Implementation Method 2
the penetrations are suitable for providing an adhesive connection with a facade element, in that an adhesive compound on the upper side partially penetrates through the penetrations
