Embed Façade Attachment Channels for Flush Concrete Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facade attachment systems for building structures face challenges in providing a secure and uniform method for mounting facade elements to concrete structures, particularly in ensuring a flush and stable integration with exterior surfaces while allowing for easy installation and removal of facade panels.
Innovation Solution
The embed facade system employs inner and outer channels configured to receive fasteners, coupled to concrete reinforcement elements, allowing for embedding in concrete structures and enabling secure attachment of facade elements with exposed channels for easy access and installation, using methods that involve temporary concrete forms and specific fastening mechanisms like T-bolts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If facade elements are mounted using traditional bracket systems or window sills, then the facade can be attached to the building structure, but the integration with exterior surfaces is not flush and uniform
Solution Approach 1:
The attachment system is embedded into the concrete structure during the pouring process itself, before the facade elements are installed. The channels are formed and positioned in advance within the wet concrete, ensuring they will be flush with the cured surface. This preliminary embedding action eliminates the need for post-concrete attachment modifications and achieves perfect flush integration.
Solution Approach 2:
Concrete acts as the intermediary medium that integrates the attachment system with the building structure. The channels are embedded in the concrete, which then becomes part of both the structural element and the mounting substrate. This intermediary approach unifies the attachment system with the exterior surface, achieving flush integration while simplifying the overall structure.
2Reliability
If facade elements are permanently fixed to the structure, then structural stability is achieved, but ease of installation and removal is reduced
Solution Approach 1:
The attachment system is divided into two distinct segments: the embedded channel portion that provides structural anchoring, and the removable fastener portion that allows easy installation and removal of facade elements. The channel remains permanently embedded in the concrete for reliable attachment, while the fasteners can be easily inserted and removed without damaging the structural integration.
Solution Approach 2:
The system transitions from a static permanent fixation approach to a dynamic system where the fasteners can be easily inserted and removed. The embedded channels provide stable structural anchoring, while the removable fasteners enable the facade elements to be dynamically installed and removed, combining security with operational flexibility.
3Stability of the object's composition
If channels are completely embedded in concrete, then structural integration is achieved, but access for fastener installation is lost
Solution Approach 1:
The channels have different qualities at different locations: the majority of the channel length is embedded in the concrete for structural integration and stability, while the ends of the channels remain exposed at the concrete surface. This local differentiation allows the embedded portion to provide anchoring strength while the exposed portions provide access for fastener installation and removal.

AI summary
An embed facade attachment system comprises an inner channel and an outer channel. The inner channel is configured to receive one or more fasteners between an upper retaining flange and a lower retaining flange. The outer channel is defined between an upper outward flange and a lower outward flange and configured to receive one or more fasteners. One of the inner channel and the outer channel is coupled to a concrete reinforcement element and another of the inner channel and the outer channel is removably coupled to a facade element by the one or more fasteners. The facade attachment is embedded in concrete with at least the inner channel or the outer channel exposed to a surface of the concrete to allow coupling of the facade element.
