Threaded Rod Locking Housing for No-Rotation Ceiling Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Installers face challenges in assembling pre-fabricated sub-assemblies on ceilings and structures without rotating threaded rods, as conventional methods require disassembly to engage rods with internal threads, leading to inefficiencies in installation labor.
Innovation Solution
A device with a housing that slidably receives a threaded rod, featuring biased plungers and a tapered portion to secure the rod within the housing, allowing for easy insertion and locking without rotation, using an anchor and bracket to embed the housing in concrete, enabling securement of the rod post-concrete pouring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional beam clamps, anchor bolts, and strut nuts are used to secure threaded rods, then the threaded rods can be engaged with internal threads, but the threaded rods must be rotated into the internal threads requiring disassembly of pre-fabricated sub-assemblies
Solution Approach 1:
Instead of rotating the threaded rod into internal threads as in conventional devices, this invention inverts the approach by having the threaded rod slide linearly into a housing that contains biased plungers which engage the rod's external threads. This eliminates the need for rotation and allows direct insertion of pre-fabricated sub-assemblies, significantly reducing installation labor time while maintaining ease of assembly.
2Productivity
If pre-fabricated sub-assemblies with threaded rods are used, then installation labor savings are maximized, but the threaded rods cannot be assembled without rotating unless the sub-assemblies are disassembled
Solution Approach 1:
The invention inverts the conventional assembly approach by designing a device where the threaded rod inserts linearly without rotation. The biased plungers automatically engage the rod's external threads during linear insertion, enabling pre-fabricated sub-assemblies to be assembled directly in the field without disassembly, thereby maximizing installation efficiency while maintaining ease of operation.
Solution Approach 2:
The biased plungers are designed to automatically engage the threaded rod during linear insertion without requiring manual intervention for threading. The spring bias ensures the plungers move outward to engage the rod's external threads as it is inserted, making the assembly process self-service and eliminating the need for rotation or disassembly of pre-fabricated components.
3Reliability
If threaded rods are rotated into internal threads using conventional methods, then secure connection is achieved, but the process requires disassembly of pre-fabricated sub-assemblies leading to installation inefficiencies
Solution Approach 1:
The invention inverts the connection method by having the threaded rod slide linearly into a housing with biased plungers that engage the rod's external threads, rather than rotating the rod into internal threads. This maintains connection security through positive engagement of the plungers with the rod while eliminating the need for disassembly and rotation, thereby improving installation labor savings and productivity.
Solution Approach 2:
The biased plunger mechanism automatically engages the threaded rod during linear insertion, providing secure connection without requiring manual threading operations. The spring bias ensures reliable engagement of the plungers with the rod's external threads, maintaining connection security while enabling quick assembly of pre-fabricated sub-assemblies without disassembly, thus improving installation productivity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates quick and efficient assembly of threaded rods by allowing securement without rod rotation, enhancing labor savings and ease of assembly in trapeze and anchor bolt applications, while maintaining adjustability and secure locking.
Implementation Method 1
A biasing member can be arranged between the housing flange and the bracket to bias the housing away from the bracket and the anchor
Implementation Method 2
Aa tapered portion within the securement portion can be configured to urge the plungers toward the threaded rod when the threaded rod is loaded in a withdrawal direction
