Snap-To-Grid Sprinkler Bracket for T-Bar Torsion Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire sprinkler support assemblies are cumbersome to install and do not efficiently secure sprinkler heads to T-bar beams in ceiling grid systems, particularly under high fluid pressure conditions, which can lead to misdirection of the suppression fluid.
Innovation Solution
A bracket assembly comprising a first plate and a second plate, with a seating frame that straddles the beam, and a fastener that adjusts the distance between the plates to securely anchor the sprinkler support assembly to the T-bar beam, allowing for easy installation and secure positioning of the sprinkler head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fasteners (screws or bolts) are used to secure the bracket to the ceiling structure, then the connection strength is sufficient to withstand high fluid pressure, but the installation process becomes time-consuming and requires special tools
Solution Approach 1:
The bracket assembly is divided into multiple components: a first plate for attachment to the ceiling structure, a second plate for attachment to the bracket bar, and a seating frame with straddling members. This segmentation allows each component to be optimized independently and facilitates easier installation while maintaining connection strength through distributed fastening points.
Solution Approach 2:
The bracket assembly incorporates adjustable elements that allow dynamic adaptation during installation. The seating frame can be positioned at different locations along the bracket bar, and the straddling members can accommodate variations in beam dimensions, enabling quick adjustment without requiring precise pre-measurement or specialized tools.
2Ease of operation
If the bracket design is simplified for easier installation, then installation time is reduced, but the ability to resist side, rotational, and torsional forces under high pressure may be compromised
Solution Approach 1:
The bracket assembly merges multiple functional elements into a single integrated structure: the first plate provides ceiling attachment and force distribution, the seating frame with straddling members provides mechanical interlocking and rotational resistance, and the second plate provides bracket bar attachment. This combination achieves high strength against side, rotational, and torsional forces while maintaining ease of installation through a modular design that requires only basic fastening operations.

AI summary
A fire sprinkler support assembly includes a beam defining a first side and a second side; a bracket bar; and a bracket assembly coupled to an end of the bracket bar, the bracket assembly comprising: a first plate defining a first vertical section oriented substantially perpendicular to the bracket bar, the first plate having a first end coupled to the bracket bar and a second end coupled to the beam, the first plate defining a first plate opening; a second plate actionable relative to the first plate, the second plate extending through the first plate opening in the first plate; and a fastener coupling the first plate to the second plate and operable to adjust a distance between the first plate and the second plate.
