Angled Bracket Drop Netting for Debris Containment and Worker Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drop netting systems for multi-floor construction lack effective debris containment and worker access, as they often fail to provide sufficient clearance from the edge of slabs, leading to inefficient debris management and restricted worker mobility.
Innovation Solution
A drop netting system comprising a series of angled brackets around the perimeter of slabs, including terminal, corner, and add-on brackets, which suspend a net away from the edge, allowing for debris containment while maintaining worker access, with modular design for adaptability to various building shapes and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If drop netting is installed close to the edge of slabs, then debris containment is improved, but worker access is restricted
Solution Approach 1:
The netting system transitions from a two-dimensional plane attached directly to the slab edge to a three-dimensional configuration by suspending the netting below the slab surface using vertical suspenders. This vertical dimensionality allows the netting to be positioned away from the edge while maintaining debris containment effectiveness, thereby providing workers with access space at the slab edge.
Solution Approach 2:
Vertical suspenders act as intermediary elements between the slab and the netting. These suspenders hold the netting at a distance from the slab edge, serving as a mediator that maintains debris containment while creating clearance for worker movement and equipment operation at the edge.
2Ease of operation
If drop netting is suspended away from the edge, then worker access is improved, but debris containment effectiveness is reduced
Solution Approach 1:
By utilizing the vertical dimension through suspenders, the netting can be positioned away from the edge for worker access while extending horizontally to maintain debris containment coverage. The vertical suspension creates a three-dimensional containment zone that remains effective despite the horizontal distance from the edge.
3Adaptability or versatility
If a modular bracket system is used, then adaptability to various building configurations is improved, but device complexity increases
Solution Approach 1:
The bracket system is divided into modular components including corner brackets, mid-side brackets, and adjustable suspenders that can be independently configured. This segmentation allows the system to be adapted to various building shapes and sizes by selectively assembling different bracket configurations without requiring a completely custom design for each project.
Solution Approach 2:
The bracket system incorporates adjustable and reconfigurable elements that can be dynamically adapted to different building configurations. The modular design allows brackets to be positioned, angled, and connected in various arrangements depending on the specific building geometry, providing versatility while maintaining a standardized component library.

AI summary
A drop netting system configured to installation on a building slab such as a balcony to protect against falling debris, overspray, concrete, and the like. The system includes plurality of spaced apart brackets disposed around the perimeter of the slab so as to form an array of attachment points for a drop net to be attached to and suspended from the brackets. The brackets extend outward from the edge of the slab and are each optionally angled slightly upward from the surface of the slab. A drop net is secured to the distal end of each bracket and suspended therefrom such that the drop net is spaced away from the edge of the slab to permit construction workers to have access of the slab edge in order to carry out construction work. The drop netting system can be installed on adjacent floors to encase the space between the floors.
