Insulation Brick with Partitioned Channels for Fire Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermal insulation composite systems for buildings face issues such as high maintenance costs due to algae growth, low mechanical strength, risk of fire, and difficulty in attaching fixtures, with vertical perforated bricks offering improved fire resistance but still risking fire spread due to the 'chimney effect' of their design.
Innovation Solution
A slotted brick design with horizontally aligned filling channels and a receptacle for a holding device, preventing vertical fire spread and allowing for direct attachment to a load-bearing wall, enhancing fire protection and installation efficiency while maintaining good insulating properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If vertical perforated bricks with large filling channels are used for thermal insulation, then good insulating properties are achieved, but fire can spread vertically due to the chimney effect
Solution Approach 1:
The filling channel is divided into multiple separate channels (first filling channel and second filling channel) that are arranged parallel to each other and separated by a partition wall. This segmentation prevents the formation of a continuous vertical pathway for fire spread, eliminating the chimney effect while maintaining thermal insulation performance through the distributed insulation material in each channel.
Solution Approach 2:
A partition wall is introduced as an intermediary element that divides the filling channel into separate sections. This partition wall acts as a fire barrier that interrupts vertical fire spread pathways while allowing the insulation material to maintain its thermal insulation function in each separated channel.
2Loss of energy
If thermal insulation composite systems with foamed plastics are used, then good insulating properties are achieved, but fire resistance is poor and toxic fumes are produced
Solution Approach 1:
The invention changes the physical configuration parameter of the filling channel from a single large vertical channel to multiple smaller parallel channels separated by partition walls. This parameter change maintains the insulation volume and thermal performance while fundamentally altering the fire behavior by preventing continuous vertical combustion pathways and reducing toxic fume accumulation.
3Strength
If curtain-type rear-ventilated facades with slotted bricks are used, then mechanical strength is improved, but insulating effect is limited and cold air flows like a chimney
Solution Approach 1:
The invention transitions from the conventional horizontal slot orientation to a vertical orientation of the filling channels, but divides them into multiple parallel channels separated by partition walls. This dimensional reconfiguration maintains the structural integrity provided by the slotted brick design while improving insulation effectiveness by preventing chimney-like cold air flow through the partitioned channels.

AI summary
The invention relates to an insulation brick (1) with two outer longitudinal webs and two outer transverse webs and at least one filling channel filled with insulating material. Said insulating brick is configured as a horizontal coring brick, through which the filling channel extends parallel to the horizontal joint surface of the brick. In addition, an accommodation (8) is formed on said brick for a holding device (33). The invention further relates to a multi-layered wall (30) comprising a supporting wall element (31) and at least one additional brick wall layer (32) for insulation, being arranged internally and/or externally on the supporting wall element (31) and fastened to same, wherein the brick wall layer (32) is formed from a plurality of insulating bricks (1) according to the invention. The insulating bricks (1) are individually suspended alongside each other in rows on the supporting wall element (31) by means of holding devices (33) in such a way that the filling channels of said insulating bricks are aligned substantially to each other, wherein a plurality of rows of the insulating bricks (1) lie on top of one another and so form the brick wall layer (32). In this manner, fire protection on a multi-layered wall can be substantially improved.
