Balcony Bracket with Tension and Compression Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balcony assembly methods are inefficient and resource-intensive, often requiring significant time and labor, and can cause thermal bridges and delays in construction due to the need for scaffolding and crane usage.
Innovation Solution
A system for balcony assembly that utilizes consoles and struts to support precast concrete balconies, with anchor points in the building wall that allow for flexible installation and adjustment, enabling balconies to be installed without scaffolding and allowing for non-destructive dismantling and reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If balconies are installed using traditional methods with scaffolding and cranes, then the balcony can be securely mounted on the building, but the construction process experiences significant delays and resource consumption increases
Solution Approach 1:
The balcony system is divided into separate modular components: brackets with support heads that can be independently mounted on the building, and balconies that can be separately manufactured and then attached to the brackets. This segmentation allows parallel installation of mounting structures and balconies, eliminating the need for sequential scaffolding and crane operations, thereby improving construction speed while maintaining secure mounting.
Solution Approach 2:
The brackets are pre-mounted on the building structure before the balconies are installed. This preliminary action creates ready-to-use attachment points that eliminate the need for later scaffolding setup and crane operations, significantly accelerating the construction process while ensuring reliable balcony mounting through pre-positioned support structures.
2Ease of operation
If balconies are installed floor by floor from the bottom up after scaffolding removal, then the installation can proceed without substructures, but the crane operating time increases and resource efficiency decreases
Solution Approach 1:
Multiple brackets are pre-mounted on the building structure at different floor levels before any balconies are installed. This preliminary action creates a network of ready-to-use attachment points throughout the building, allowing balconies to be quickly attached without requiring sequential floor-by-floor installation or extended crane operations, thereby reducing crane operating time while maintaining installation simplicity.
Solution Approach 2:
The system combines multiple brackets and support heads into an integrated mounting structure that can accommodate multiple balconies simultaneously. This merging of components allows several balconies to be installed in parallel using a single crane or even manually, significantly reducing total crane operating time and improving resource efficiency compared to installing each balcony sequentially.
3Device complexity
If balconies are connected directly to the building wall, then the structure is simple, but thermal bridges are created that dissipate building energy
Solution Approach 1:
The bracket system acts as an intermediary between the building structure and the balcony, providing attachment functionality while enabling the insertion of thermal insulation materials in the gap between the building wall and balcony. This intermediary structure maintains the simple connection concept while eliminating thermal bridges through the insulating gap, preventing energy dissipation without complicating the overall connection structure.
4Manufacturing precision
If balconies are made as prefabricated concrete elements, then manufacturing precision is improved, but the weight of the components increases
Solution Approach 1:
The system segments the balcony into a heavy prefabricated concrete balcony element and separate lightweight bracket components. The heavy balcony element can be manufactured with high precision in a controlled factory environment, while the brackets are smaller, lighter components that can be easily mounted on the building. This segmentation maintains manufacturing precision benefits while reducing the weight of components that need to be maneuvered during installation.
