Spring-Loaded Clip for Steel Corner Bead Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing corner beads on structural steel for fireproofing are inefficient and prone to inaccuracy, requiring significant skill and time to achieve the correct thickness of fireproofing material, especially at corners where precise alignment is challenging.
Innovation Solution
A spring-loaded metal clip with notches is used to securely attach corner beads to structural steel members, providing precise positioning and easy installation by engaging the longitudinal wires of the corner bead into fixed notches, allowing for quick and accurate application of fireproofing material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adjustable legs (flanges) are used on V-shaped corner beads to regulate fireproofing thickness, then the corner bead can be adjusted to different positions, but the alignment with adjacent surfaces becomes difficult and requires great skill and substantial time
Solution Approach 1:
The patent applies preliminary action by providing pre-drilled holes at fixed positions on the corner bead that correspond to predetermined locations on the steel member. This allows the corner bead to be positioned accurately without requiring skillful adjustment of legs, as the positioning is already prepared in advance. The holes are located at specific distances from the vertex to ensure proper fireproofing thickness regulation.
Solution Approach 2:
The patent uses an intermediary approach by introducing a positioning system consisting of pre-drilled holes and corresponding anchors or fasteners. This intermediary positioning mechanism mediates between the corner bead and the steel member, providing accurate alignment without requiring the worker to skillfully adjust the adjustable legs. The intermediary holes guide the placement and ensure proper positioning.
2Manufacturing precision
If adjustable legs are used to establish correct fireproofing thickness, then the corner bead can be positioned accurately, but great skill and substantial time are required for installation
Solution Approach 1:
The pre-drilled holes at fixed positions on the corner bead represent preliminary action, where the positioning information is encoded into the component itself during manufacturing. This eliminates the time-consuming process of measuring and adjusting during installation, while maintaining precise fireproofing thickness through the predetermined hole locations.
Solution Approach 2:
The patent applies copying by transferring the positioning information from the steel member geometry to the corner bead through pre-drilled holes. The holes copy the required positioning data, allowing rapid installation without requiring skilled measurement and adjustment, thereby reducing installation time while maintaining precision.
3Reliability
If conventional corner bead installation methods are used, then the corner bead can be attached to the steel member, but the process is inefficient and prone to inaccuracy
Solution Approach 1:
The pre-drilled holes at predetermined positions represent preliminary action that ensures reliable and accurate attachment. The holes are positioned based on precise calculations to ensure proper fireproofing thickness, eliminating the inaccuracy associated with conventional methods while maintaining efficiency through simplified installation.
Solution Approach 2:
The patent applies parameter changes by fixing the position parameters of the attachment holes at predetermined distances from the vertex. This changes the installation process from one requiring skillful adjustment to one where the parameters are already optimized, improving both reliability and productivity simultaneously.
