Mounting collar for a ventilation element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Installing ventilation elements, such as fire dampers, in fire-resistant partition walls, especially suspended ceilings, is laborious and requires complex constructions, as existing ventilation elements designed for rigid walls are not suitable for light and thin partition walls.
Innovation Solution
A mounting collar made from fire-resistant and heat-insulating material, such as fibre-reinforced plaster, which surrounds the ventilation element and extends through a wall passage, providing necessary fire-resistant and heat-insulating properties, allowing for the use of standard ventilation elements and simplifying installation by supporting the collar within the partition wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standard ventilation elements designed for rigid walls are used in fire-resistant partition walls, then the ventilation function is achieved, but the installation becomes laborious and complex
Solution Approach 1:
The mounting collar acts as an intermediary component between the standard ventilation element and the fire-resistant partition wall. It provides a simplified interface that enables easy installation of standard ventilation elements in partition walls without requiring complex construction, while maintaining fire-resistant properties through its fire-resistant material composition and integration with the wall structure.
2Reliability
If ventilation elements are installed in suspended ceilings, then ventilation through the ceiling is achieved, but the securing arrangement must prevent fire penetration and prevent the element from falling
Solution Approach 1:
The mounting collar serves as a mediator that simultaneously addresses fire resistance and installation ease in suspended ceilings. It provides a secure mounting structure that prevents the ventilation element from falling while maintaining fire-resistant properties through its fire-resistant material and integration with the ceiling structure.
Solution Approach 2:
The mounting collar changes the physical parameters of the installation system by providing a rigid, fire-resistant structure that can be securely attached to suspended ceiling components. This allows standard ventilation elements to be mounted reliably in suspended ceilings without requiring complex adaptation, as the collar adapts to the ceiling structure and provides the necessary support and fire resistance.
3Object-affected harmful factors
If a mounting collar made of fire-resistant material is used, then fire penetration is prevented, but the collar must extend through the wall passage requiring proper positioning
Solution Approach 1:
The mounting collar is designed with preliminary positioning features that facilitate accurate installation in the wall passage before final securing. The collar's structure includes elements that guide its placement and ensure proper positioning, reducing the need for high precision during installation while maintaining fire-resistant integrity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mounting collar simplifies the installation of ventilation elements in fire-resistant partition walls by providing fire-resistant and heat-insulating properties, enabling the use of standard ventilation elements and ensuring effective fire penetration prevention, while maintaining air circulation and aesthetic appeal.
Implementation Method 1
the sleeve is substantially made from a fire-resistant and heat-insulating material, such as a material comprising plaster
Implementation Method 2
If the fire-resistant and heat-insulating material comprises plaster, the plaster will provide a cooling effect in case of fire due to the chemically bound water which is present in plaster
