Rotatable Sprinkler Support Bracket for Secure T-Bar Grid Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire sprinkler support assemblies are time-consuming to install and do not efficiently secure sprinkler heads to T-bar beams in ceiling grid systems, especially under high fluid pressure conditions, which can lead to misdirection of the fire suppression fluid.
Innovation Solution
A bracket assembly for fire sprinkler support systems that includes a bracket bar extending transverse to a beam, with a seating frame and a second plate that can be rotated relative to a first plate, using a fastener or lever assembly to securely anchor the bracket assembly to the 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 time increases significantly
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. This segmentation allows for simplified installation while maintaining connection strength through distributed fastening points.
Solution Approach 2:
The bracket assembly is pre-configured with the first and second plates positioned on opposite sides of the beam, with fastener openings aligned. This preliminary arrangement eliminates the need for complex alignment during installation, reducing installation time while ensuring proper connection strength.
2Ease of operation
If the bracket assembly uses a rotatable second plate with fastener coupling, then the ease of installation is improved, but the device complexity increases
Solution Approach 1:
The second plate is designed to be rotatable relative to the first plate, allowing dynamic adjustment during installation to accommodate slight misalignments or different beam positions. This rotational capability simplifies installation while the fastener coupling mechanism maintains structural integrity.
Solution Approach 2:
The fastener acts as an intermediary element that couples the first and second plates together. The fastener openings in both plates are positioned to receive the fastener, providing a simple yet effective connection mechanism that balances ease of installation with structural reliability.

AI summary
A bracket assembly, a fire sprinkler support assembly, and a method for using a bracket assembly are disclosed. The bracket assembly can comprise a first plate having a first end and a second end, the first plate defining a first plate opening and a first fastener opening; a second plate actionable relative to the first plate and defining a second fastener opening, the second plate extending through the first plate opening in the first plate; and a fastener coupling the first plate to the second plate, wherein the fastener is a screw defining a threaded exterior surface, the screw configured to engage the first fastener opening and the second fastener opening.
