Expansion Joint Profile With Tread Surface And Fire Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional expansion joint profile arrangements lack sufficient slip resistance, are prone to wear, and fail to provide adequate protection against moisture and corrosion, leading to increased risk of accidents and maintenance costs, especially in high-traffic areas and adverse weather conditions.
Innovation Solution
A joint profile arrangement featuring anchoring profiles with a tread surface, a bridging bar profile with fork- and tongue-shaped sections, and a longitudinal sleeve for moisture protection, combined with a fire protection insert and cushion insert for sound insulation, ensuring traction, durability, and protection against moisture and fire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional expansion joint profile arrangements are used to bridge joints, then the joint can be bridged, but the surface becomes smooth which increases slipping risk and reduces tread resistance
Solution Approach 1:
The patent applies local quality by providing a tread surface with specific surface characteristics (roughness, patterns, or textures) only on the walking surface of the joint profile, while keeping other parts of the profile smooth or differently finished. This localized surface treatment increases friction and reduces slipping risk without affecting the overall structural function of the joint bridge.
2Reliability
If conventional joint profiles are used, then the joint can be bridged, but the surface is prone to severe wear and abrasion
Solution Approach 1:
The patent employs composite materials by combining different material properties in the joint profile structure. The tread surface may use abrasion-resistant materials such as rubber, plastic, or treated metal surfaces, while the structural core uses appropriate structural materials. This composite approach ensures both structural integrity and surface durability against wear and abrasion.
3Reliability
If conventional expansion joint profiles are used, then the joint can be bridged, but protection against moisture and corrosion is insufficient
Solution Approach 1:
The patent introduces an intermediary protective layer or coating on the joint profile that acts as a barrier between the metal structure and the environment. This intermediary layer (such as protective coatings, cladding, or sealing layers) prevents direct contact between moisture and the structural material, thereby reducing corrosion risk while maintaining the joint bridging function.
4Reliability
If conventional joint profiles are used, then the joint can be bridged, but the structure is complex and requires multiple components for protection
Solution Approach 1:
The patent merges multiple protective functions into a single integrated joint profile structure. The tread surface, protective coating, and structural elements are combined into one unified component that performs both structural bridging and protective functions, reducing the need for separate protective elements and simplifying the overall structure.
