Frameless Fire Protection Glass Door with Intumescent Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire protection closures with frameless fire-resistant glazing solutions compromise on light passage and visual appeal due to the need for numerous frame parts, and while frameless solutions improve light passage, they still require wooden profiles for stability and fireproofing.
Innovation Solution
A fire protection closure with a glass door and pivotable, profile-free design featuring two parallel, spaced fireproof glass panes edge-bonded with a fire protection gel-filled space, where the edge bond is offset to form an abutting edge groove containing an intumescent strip with a sealing groove, eliminating the need for a door frame and maximizing light passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frame parts are used to ensure stability and fireproofing, then fire protection properties are improved, but light passage and visual appeal are reduced
Solution Approach 1:
The patent removes the frame structure entirely from the fire protection closure, extracting the disturbing element that blocked light while maintaining fire protection through alternative means (fire-resistant glass panes and intumescent seals)
Solution Approach 2:
The patent changes the material parameters by using fire-resistant glass panes with specific properties and intumescent sealing strips that expand under heat, providing fire protection without requiring visible frame structures
2Reliability
If frame parts are used to ensure stability and fireproofing, then fire protection properties are improved, but visual appeal is reduced
Solution Approach 1:
The patent removes the frame structure entirely from the fire protection closure, extracting the disturbing element that blocked light while maintaining fire protection through alternative means (fire-resistant glass panes and intumescent seals)
3Stability of the object's composition
If frame structures are used to hold fire-resistant panes, then structural stability is improved, but device complexity increases
Solution Approach 1:
The patent removes the frame structure entirely from the fire protection closure, extracting the disturbing element that blocked light while maintaining fire protection through alternative means (fire-resistant glass panes and intumescent seals)
Solution Approach 2:
The patent combines the fire-resistant glass panes directly with the wall opening reveal and lintel, merging the structural support function into the building structure itself rather than using separate frame components
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 solution achieves enhanced light passage and attractiveness with improved fire protection and smoke tightness, as the all-glass construction reduces visible frame elements, while the intumescent strip ensures reliable sealing during fires.
Implementation Method 1
the enclosed space between the fireproof glass panes is filled with a fire protection gel
Implementation Method 2
an intumescent strip is used, characterized in that in the intumescent strip at least one sealing groove is formed, in which a seal is inserted

AI summary
The fire protection closure (1) is inserted in a wall opening (2) connecting the two rooms with an embrasure (3) and a drop structure (4) and comprises a glass door (5) with a profile-free door leaf (6) that is movable in a direction and is made of a fire-resistant panel (7). The door leaf is adjoined to the embrasure of the wall opening on a longitudinal side in a frame-less manner.
