Angled Sprinkler Support Assembly for T-Bar Grid Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire sprinkler support assemblies face challenges in securely mounting to ceiling grid systems, particularly in grid-type ceilings where limited space between tiles and inner structures lead to weak points at bends, prone to failure under high fluid pressure.
Innovation Solution
A snap-to-grid angled bracket assembly with a seating frame and angled plates that extend from an upper wall, allowing for secure coupling to a T-bar beam with high clearance for ceiling tile installation, enabling faster and tool-less installation by snapping onto the beam and securing with fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If leg brackets are offset with respect to the support member of the ceiling grid to address limited space, then the sprinkler head can be positioned correctly, but a weak point is created at the bend in the leg which is prone to failure
Solution Approach 1:
The bracket is divided into multiple segments: a horizontal portion that attaches to the ceiling grid beam, a vertical portion that provides the offset positioning, and a sprinkler head support portion. This segmentation allows each part to perform its function optimally while distributing stress away from critical bend points.
Solution Approach 2:
The bracket design transitions from a simple L-shaped offset to a three-dimensional structure with the horizontal portion extending perpendicular to the beam, the vertical portion providing offset, and the support portion holding the sprinkler. This multi-dimensional approach creates clearance for ceiling tiles without concentrating stress at a single bend point.
2Reliability
If conventional fasteners are used to secure the sprinkler support assembly to the ceiling structure, then the sprinkler can be firmly attached, but the installation process becomes time-consuming and requires special tools
Solution Approach 1:
The bracket assembly is designed to be self-aligning and self-securing. The horizontal portion slides onto the ceiling grid beam and is retained by the bracket's geometry, allowing installation without special tools or complex fastening procedures while maintaining secure attachment.
Solution Approach 2:
The bracket incorporates movable or adjustable components that allow the installer to quickly position and secure the assembly. The design transitions from a static, rigid fastening system to a dynamic installation process where the bracket can be easily positioned and then locked into place.
