Composite Wall Structural Inserts Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current SIP composite walls face limitations in mechanical strength, particularly when constructing multiple floors, as they are weakly load-bearing and the joining process creates thermal bridges due to the use of chaining elements that interrupt the insulation layer.
Innovation Solution
Incorporating load-bearing structural inserts that extend into the insulation layer between the facing panels, which are designed to transfer loads and provide structural reinforcement without creating thermal bridges by maintaining insulation between the inserts and panels, allowing for the use of less dense insulation materials and enhancing the structural integrity of the composite wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If load-bearing structural inserts are integrated into the insulation layer to reinforce the wall, then the mechanical strength is improved, but thermal bridges are created between the facing panels
Solution Approach 1:
The patent introduces an intermediary material (insulating material or air gap) between the load-bearing structural insert and the facing panels. This intermediary breaks the direct thermal contact path while allowing the insert to maintain its load-bearing function, thus resolving the contradiction between mechanical strength reinforcement and thermal bridge prevention
Solution Approach 2:
The insulation layer is segmented into multiple zones: some regions contain the structural inserts for load-bearing, while other regions maintain continuous insulation material to prevent thermal bridges. This segmentation allows the system to simultaneously achieve both mechanical reinforcement and thermal insulation performance
2Object-affected harmful factors
If dense insulation material is used to prevent thermal bridges, then thermal insulation performance is improved, but the structural strength of the wall is reduced
Solution Approach 1:
The wall structure is divided into functional zones: the insulation layer provides thermal insulation, while separate load-bearing structural inserts provide mechanical strength. This segmentation allows each component to be optimized for its specific function without compromising the other
Solution Approach 2:
The patent employs a composite wall structure combining different materials with complementary properties: insulation materials for thermal performance, structural inserts for mechanical strength, and facing panels for surface protection. This composite approach resolves the contradiction by distributing functional requirements across multiple materials
3Strength
If facing panels with high structural strength are used, then the load-bearing capacity is improved, but the thermal insulation performance is reduced
Solution Approach 1:
The wall assembly is segmented into distinct functional layers: facing panels for structural support, insulation layer for thermal performance, and structural inserts for load-bearing reinforcement. This segmentation allows each layer to be optimized independently, resolving the contradiction between structural strength and thermal insulation
Solution Approach 2:
The structural inserts serve multiple functions simultaneously: they provide load-bearing capacity, connect the facing panels, and are surrounded by insulation material to maintain thermal performance. This multi-functionality resolves the contradiction by combining structural and thermal requirements in a single integrated solution

Function Achieved in This Case
This solution significantly enhances the mechanical strength of SIP composite walls, allowing for multi-floor construction while maintaining thermal insulation performance and reducing the risk of thermal bridges, thus improving the overall structural resistance and construction efficiency.
Implementation Method 1
As this or these inserts are trapped in the rigid or semi-rigid insulation layer, this insulation layer acts on the insert or inserts as a stiffener, by increasing the structural resistance of the insert or inserts within the composite wall, both in compression and in flexion
Implementation Method 2
part of the insulation layer is interposed between each panel of facing and the or each insert, at least the common part of this insert... no significant thermal bridge is created, horizontally, between the two facing panels by the insert(s) in the insulation layer

AI summary
The invention relates to a composite wall (100) comprising a rigid or semi-rigid insulating layer (113), inserted between two facing panels (111, 112) and at least one load-bearing structural insert (116), which extends lengthwise between the two opposite horizontal edges (100A, 100C) of the composite wall and which is arranged in the insulating layer. Along a first (100A) of the two opposite horizontal edges of the composite wall, the insulating layer forms, in the portion thereof facing a first (112) of the two facing panels, a projection (113.A1) that extends lengthwise along this first horizontal edge, whereas the portion thereof facing the second facing panel forms a first tying cavity (113A.2) that extends along the projection. Along the second horizontal edge (100C) of the composite wall, the insulating layer forms, in the portion thereof facing the first facing panel, a raised joining element (113C.1) matching the projection, which extends lengthwise along the second horizontal edge of the composite wall, whereas the portion thereof facing the second facing panel forms a second tying cavity (113C.2) that extends along the joining element. In addition, the or each load-bearing insert is provided, at each of the longitudinal ends thereof, with means (116A, 116B, 116C, 116D) for rigidly connecting same with another inserted tying cavity (131, 132), arranged in the first and second tying cavities, respectively.
