Hat Profile Beam With Passage Openings For Sealed Ventilation Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation duct networks in prestressed concrete ceilings face challenges in simplifying the connection of ventilation ducts between ceiling elements and the rest of the network, particularly in ensuring secure and sealed connections.
Innovation Solution
The proposed solution involves using connecting elements such as sleeves or pipe sections with seals and U-shaped flanges to connect passage openings in the hat profile support, allowing for flexible and sealed connections between ventilation ducts and ceiling elements, which can be adapted to accommodate different diameters and include additional seals for closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional core drillings or cut-outs are used to create ventilation ducts in prestressed concrete slabs, then ventilation ducts can be connected to the rest of the network, but the connection process becomes complex and requires additional manufacturing steps
Solution Approach 1:
The passage openings are pre-formed in the hat profile support during manufacturing, eliminating the need for core drillings or cut-outs during construction. This preliminary preparation simplifies the subsequent connection process by providing ready-to-connect interfaces with integrated sealing surfaces and U-shaped flanges.
Solution Approach 2:
Connecting elements serve as intermediaries between the ventilation ducts and the hat profile support. These connecting elements feature U-shaped flanges that interface with the passage openings, providing a standardized connection mechanism that simplifies the overall assembly process.
2Adaptability or versatility
If passage openings are created in the hat profile support for connecting ventilation ducts, then connection flexibility is improved, but ensuring secure and sealed connections becomes more challenging
Solution Approach 1:
The sealing function is merged into the connection structure itself. The U-shaped flange of the connecting element integrates with the passage opening to form a unified connection interface, eliminating the need for separate sealing components and ensuring reliable sealing through the inherent geometry of the combined structure.
Solution Approach 2:
Sealing rings or gaskets are used as flexible elements within the connection interface. These flexible sealing components adapt to the geometry of the passage openings and U-shaped flanges, ensuring reliable sealing while accommodating manufacturing tolerances and providing flexibility in the connection.
3Reliability
If U-shaped flanges are added to surround passage openings for better connection, then connection security is improved, but the device complexity increases
Solution Approach 1:
The U-shaped flange structure serves multiple functions simultaneously: it provides mechanical support for the connection, creates a sealing surface, and offers a standardized interface for attaching ventilation ducts. This multi-functionality reduces the need for additional components and simplifies the overall connection system despite the enhanced security requirements.

AI summary
The invention relates to a hat profile beam, comprising at least one support flange for ceilings and/or ceiling elements having air-conducting channels. In order to simplify the connection of the ventilation channels in the ceilings and the ceiling elements to the rest of the ventilation network, passages are provided in the longitudinal side of the hat profile beam above the support flange. Said passages can be connected to the channels arranged in the ceilings and/or ceiling elements.
