Thermal Break with Breakable Profile for Insulating Floor Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for insulating floors with interjoists and thermal breaks are cumbersome and inefficient, particularly when dealing with false spans, as they require precise cutting and complex reconfiguration, leading to fragile and aesthetically unsatisfactory results, and do not effectively adapt to both normal and reduced center distance configurations.
Innovation Solution
The edge thermal breaker and insulating interjoist designs feature breakable parts with inclined faces and transverse ribs, allowing for adaptable fitting on both central parts and inclined longitudinal wings, enabling easy modification of the thermal breaker's profile to suit various span configurations without additional fasteners or connectors, ensuring precise positioning and mechanical retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If precise cutting and complex reconfiguration are performed to adapt interjoists to false spans, then the interjoist can fit the reduced center distance configuration, but the results become fragile and aesthetically unsatisfactory
Solution Approach 1:
The thermal breaker is divided into breakable parts that can be selectively removed. This segmentation allows the thermal breaker to adapt to different span configurations (normal or false spans) without requiring cutting or reconfiguration of the interjoist itself, thereby maintaining structural integrity while providing adaptability.
Solution Approach 2:
The breakable parts are designed to be easily extracted from the thermal breaker structure. By removing these specific portions, the thermal breaker adapts to reduced center distance configurations without compromising the interjoist's structural integrity, avoiding the fragility issues associated with traditional cutting methods.
2Ease of operation
If traditional thermal breakers are used on false spans, then installation is simplified, but the thermal breaker cannot be properly positioned on the inclined longitudinal wings
Solution Approach 1:
The thermal breaker is designed with dynamic characteristics through its breakable parts, allowing it to change its configuration from a complete structure to a modified structure. This dynamic adaptability enables proper positioning on inclined longitudinal wings in false spans while maintaining ease of installation through a standardized base design.
Solution Approach 2:
The physical parameters of the thermal breaker are changed by removing breakable parts, transforming it from a standard configuration to a modified configuration. This parameter change allows the thermal breaker to accommodate different span types without complicating the installation process, as the removal mechanism is designed to be simple.
3Adaptability or versatility
If the thermal breaker profile is modified to fit false spans, then adaptability improves, but additional fasteners or connectors are required
Solution Approach 1:
The thermal breaker's breakable parts are designed to be self-contained within the original structure, eliminating the need for external fasteners or connectors. The adaptation to different span configurations is achieved through internal modification of the thermal breaker itself, not by adding external components, thus avoiding increased device complexity.
4Manufacturing precision
If complex cuts are performed on interjoists, then precise fitting is achieved, but the number of operations increases and implementation becomes tedious
Solution Approach 1:
The breakable parts are pre-configured in the thermal breaker during manufacturing, with predetermined removal points and geometries. This preliminary preparation ensures that when installation occurs, the adaptation to different span configurations requires minimal on-site operations, thereby maintaining high fitting precision while improving installation efficiency.

AI summary
The present invention concerns a thermal break (10), the lower face (12) of which is at least delimited by a horizontal plane and comprises at least one face (162) inclined relative to said horizontal plane and configured to rest on an inclined longitudinal wing (212) of a case bay element (20) and engagement means (121, 122) arranged to mechanically link said thermal break (10) to said case bay element (20) provided with complementary engagement means (213, 214). Said inclined face (162) is provided on at least one breakable portion (16) formed in the thickness of the thermal break (10), making it possible to modify the profile of the lower face (12) of said thermal break in a simple and swift manner, such that it is suitable both for a normal case bay element arranged in a span with normal axial spacing and for a cut case bay element arranged in a span having areduced axial spacing or false axial spacing.
