Anchoring Sleeve for Thermal Insulation Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal insulation components face challenges in anchoring tensile reinforcement elements when there are space constraints, particularly with adjacent components having level differences, as traditional bent, stepped, or loop-shaped courses do not effectively reduce anchoring length, and headed bolts require precise on-site reinforcement placement.
Innovation Solution
The use of an anchoring sleeve made of concrete building material with a radial outward profile surrounding the tensile reinforcement element, which enlarges the lateral surface area for improved anchoring, allowing for reduced tensile reinforcement element length and effective anchoring in components with reduced horizontal space, and is designed to absorb stress and transfer forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If traditional bent, stepped, or loop-shaped tensile reinforcement elements are used, then they can extend into adjacent components with different height levels, but they do not effectively reduce anchoring length and require more horizontal space
Solution Approach 1:
The patent introduces an anchoring sleeve that extends in the vertical dimension (radially outward from the joint) to provide anchoring functionality. This vertical extension allows the tensile reinforcement element to be anchored without requiring extensive horizontal protrusion into adjacent components, thereby reducing the anchoring length in the horizontal direction while maintaining installation flexibility across different height levels.
2Length of moving object
If headed bolts with conical widenings are used, then anchoring length can be significantly reduced, but precise on-site reinforcement placement is required which is difficult to achieve
Solution Approach 1:
The anchoring sleeve is designed to automatically engage and anchor the tensile reinforcement element through its own structural features (radially outward projection and recess). The sleeve self-positions and self-anchors the reinforcement element without requiring precise pre-placement or complex installation procedures, thereby achieving reduced anchoring length while maintaining ease of installation.
3Strength
If the anchoring sleeve has a large outer diameter to increase lateral surface area for anchoring, then anchoring strength is improved, but the overall component size increases
Solution Approach 1:
The anchoring sleeve is nested around the tensile reinforcement element, with the sleeve's radially outward projection providing anchoring surfaces. This nested configuration allows the anchoring functionality to be integrated within the existing component geometry, increasing anchoring strength through the sleeve's lateral surface area without significantly increasing the overall external dimensions of the thermal insulation component.
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
This solution enables secure anchoring of tensile reinforcement elements with significantly reduced protrusion into adjacent components, facilitating installation in situations with level differences and enhancing thermal insulation by using concrete materials with lower thermal conductivity.
Implementation Method 1
the anchoring sleeve and the profile automatically have an outer lateral surface, the area of which is significantly larger than the lateral surface of the tensile reinforcement element. It is not difficult to see that such an enlargement of the lateral surface leads to a correspondingly significant improvement in the anchoring of the anchoring element in the adjacent component.
Implementation Method 2
the insulating body is responsible for thermally insulating the two components while leaving a joint
