Movable Safety Net Support Frame for High-Rise Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current safety net installation methods on construction sites require frequent disassembly and reinstallation as buildings grow taller, leading to significant time and expense, as safety nets need to be completely removed and reinstalled on higher floors, which is inefficient and costly.
Innovation Solution
A safety net support apparatus with a frame and mounting brackets that can be fixed and moved upward through aligned channels, allowing the safety net to be easily raised to higher floors without full disassembly, using a winch and pulley system or crane for vertical movement, and locking mechanisms for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If safety nets are completely removed and reinstalled on higher floors as buildings grow taller, then safety net coverage can be maintained on all floors, but significant time and expense are consumed for repeated installation and removal
Solution Approach 1:
The safety net system is divided into multiple independent sections, each serving a specific floor or range of floors. These segmented sections can be independently adjusted in height along the building structure, allowing the net on lower floors to remain in place while upper sections are repositioned to cover newly constructed floors.
Solution Approach 2:
The safety net support structure incorporates adjustable and movable components that enable dynamic repositioning of net sections along the building's vertical structure. This dynamic capability allows the safety nets to adapt to the growing building height without complete removal, maintaining coverage while reducing installation/removal cycles.
2Reliability
If safety nets are completely removed and reinstalled on higher floors, then proper positioning on new floors is achieved, but significant expense is incurred for repeated installation work
Solution Approach 1:
The safety net system is divided into multiple independent sections, each serving a specific floor or range of floors. These segmented sections can be independently adjusted in height along the building structure, allowing the net on lower floors to remain in place while upper sections are repositioned to cover newly constructed floors.
Solution Approach 2:
The safety net support structure includes pre-configured mounting points and adjustment mechanisms that are prepared in advance on the building structure. This preliminary preparation enables quick repositioning of safety net sections to new floors without extensive on-site assembly work, improving installation efficiency.
3Reliability
If a fixed safety net structure is used for lower floors, then safety coverage is provided, but the structure cannot adapt to higher floors as the building grows
Solution Approach 1:
The safety net support structure incorporates adjustable and movable components that enable dynamic repositioning of net sections along the building's vertical structure. This dynamic capability allows the safety nets to adapt to the growing building height without complete removal, maintaining coverage while reducing installation/removal cycles.
Solution Approach 2:
The safety net support system is designed with universal mounting capabilities that can accommodate multiple floor levels. The same support structure and mounting mechanisms can serve both lower and upper floors, allowing a single adaptable system to provide safety coverage throughout the building's construction process.

AI summary
A support apparatus for a construction safety net. A frame is configured with a length sufficient to span at least two floors of a building under construction, and a width defined by parallel vertical support posts. Pairs of mounting brackets are affixed at or near the edges of adjacent exposed floors of the building. Each mounting bracket has a channel portion extending beyond the edge of the respective floor and aligned with the channel portions of mounting brackets affixed on adjacent floors. The vertical support posts of the frame are movable through the vertical channels and can be lifted up into the next pair of channel portions as additional floors are built out. A locking mechanism is used to secure the vertical support posts to the brackets.
