Sliding Bracket Fastening for Cladding Panel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cladding panel fastening systems for building facades are labor-intensive and time-consuming, particularly when aligning or adjusting panels of different shapes, and may require bending or deformation, affecting the visual appearance.
Innovation Solution
A fastening system comprising a rail, a bracket, and a screw, where the rail and bracket have sliding engagement configurations, allowing for facile engagement and stable suspension of cladding panels with hanging bolts or slots, enabling efficient installation of panels of various shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If tongue and groove engagement of cladding panel edges with fasteners is used, then cladding panels can be fastened to building facade, but alignment and adjustment is time consuming and labor intensive
Solution Approach 1:
The fastening system incorporates adjustable brackets that can be dynamically positioned and repositioned during installation, allowing workers to adapt to different panel shapes and facade conditions without time-consuming realignment. The brackets feature movable components that enable quick adjustment to achieve proper engagement.
Solution Approach 2:
The system divides the fastening function into separate modular components: rails mounted on the facade, adjustable brackets that connect to rails, and cladding panels with hanging slots. This segmentation allows each component to be independently positioned and adjusted, significantly reducing alignment time during assembly.
2Stability of the object's composition
If cladding panels are bent or deformed for adjustment, then fit to surface may be improved, but visual appearance is affected
Solution Approach 1:
The adjustable bracket acts as an intermediary between the rigid cladding panel and the building facade surface. Instead of deforming the panel to achieve fit, the bracket's adjustable arms and positioning mechanisms accommodate variations in surface geometry, maintaining the panel's original shape and visual appearance while achieving proper fit.
3Ease of operation
If sliding engagement configuration is used between rail and bracket, then engagement is facile and efficient, but structural stability must be maintained
Solution Approach 1:
The sliding engagement features dynamic locking mechanisms that transition from a movable state during installation to a fixed state during service. The brackets can slide along the rails for easy positioning and adjustment, then engage locking features (such as pins, clips, or threaded fasteners) that secure the connection to maintain structural stability under load.
