Click-Fit Brick Slip Cladding With Prefabricated Rail Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cladding systems, particularly brick slip systems, face challenges such as increased onsite assembly time due to small panel sizes, the need for numerous mounting points, and the use of adhesives that can fail or release toxins, along with insufficient cavities between panels and labor-intensive mechanical fixing of horizontal rails.
Innovation Solution
A cladding assembly with prefabricated receiving and securing means for horizontal rails on upright support members, allowing for easy installation without additional mechanical fixings, using flexible transverse rails that adjust between configurations to fit into aligned openings or slots in the upright members, and engaging with brick slips for a secure fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brick slips are individually attached to panels using adhesives, then the cladding provides a brick-like appearance, but the adhesives can fail over time and release toxins during fire
Solution Approach 1:
The patent removes the adhesive component entirely from the cladding system. Instead of using adhesive to attach brick slips to panels, the system uses a mechanical retention mechanism where brick slips are held in place by a framework of vertical studs and horizontal rails that engage with the slips through recesses and protrusions.
Solution Approach 2:
The patent introduces a mechanical framework (studs and rails) as an intermediary between the brick slips and the building structure. This framework serves as the mediating mechanism that secures the brick slips without requiring adhesive, thereby eliminating the harmful effects of adhesive failure and toxin release.
2Shape
If small brick slip panels (approximately 0.5 m2) are used, then the cladding provides a brick-like appearance, but the number of mounting points increases and installation time increases
Solution Approach 1:
The patent divides the cladding system into modular components: vertical studs, horizontal rails, and brick slip panels. This segmentation allows for standardized, pre-fabricated units that can be quickly assembled on-site, reducing installation time despite the small size of individual panels.
Solution Approach 2:
The framework of vertical studs and horizontal rails is assembled on-site before the brick slips are attached. This preliminary assembly creates a ready-made structure that speeds up the subsequent attachment of brick slips, as the retention mechanism is already in place.
3Strength
If horizontal rails are mechanically fixed to vertical studs, then the rails are securely attached, but the assembly process consumes huge amounts of time
Solution Approach 1:
The horizontal rails are designed with features that enable self-securing to the vertical studs without requiring additional mechanical fixings. The rails engage with the studs through pre-formed connections that automatically secure the rails in place during assembly, eliminating the need for time-consuming separate fastening operations.
Solution Approach 2:
The patent combines the attachment function into the rail-stud connection itself. The horizontal rails are integrated with the vertical studs through a unified connection mechanism that provides both structural support and secure attachment in a single operation, rather than requiring separate attachment steps.
4Strength
If traditional mounting arrangements are used, then the cladding panels are secured to the building structure, but the cavity between the panel and building structure is insufficient (less than 50 mm)
Solution Approach 1:
The patent uses flexible horizontal rails that can adjust between different configurations. These rails are designed to be adaptable, allowing them to accommodate varying distances between the vertical studs and the brick slip panels, thereby ensuring the required 50 mm cavity depth can be maintained while still providing secure attachment.
