Noise-Barrier Web With Elastic Mounts for Constraint-Free Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Attaching a web to noise barriers is challenging due to dynamic stimulation of neighboring posts by vehicles, causing tensile and compressive forces that make it difficult to install without play or constraints, especially in structures like overpass sound barriers where conventional accessibility is limited.
Innovation Solution
A bridge-like structure with brackets, outriggers, and a grating system using elastic support elements to compensate for the dynamic movements of uprights, allowing the web to be mounted without constraints, with damping elements to absorb and transfer loads effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the web is rigidly attached to the uprights, then the structural strength is improved, but the dynamic movements of neighboring uprights cause play and constraints in the installation
Solution Approach 1:
The patent applies dynamics by making the connection between the web and uprights movable rather than rigid. The web is attached to brackets that are mounted on the uprights, allowing the web to move independently with each upright. This dynamic connection accommodates the differential movements caused by passing vehicles while maintaining structural integrity through the bracket mounting system.
2Ease of operation
If the web is made movable to accommodate upright movements, then the ease of installation is improved, but the load transfer to uprights becomes less effective
Solution Approach 1:
The patent uses brackets as intermediary elements between the web and uprights. These brackets serve as mediators that connect the web to the uprights while allowing for movement. The brackets transfer loads from the web to the uprights through their mounting connection, effectively combining the benefits of movable installation with proper load transfer capability.
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
Enables constraint-free installation and stable mounting of the web on noise barriers, accommodating dynamic loads while ensuring electrical insulation and stability, even in complex structures like high retaining walls.
Implementation Method 1
the grating rests on the cantilevers via elastic support elements, allowing the web and the grating to easily compensate for the web's twists
Implementation Method 2
The second bearing has an elastic damping element

AI summary
A web for mounting on a partition wall, in particular a noise barrier (1) on railways or roads, has brackets (8) that are to be mounted on uprights (2) of the partition wall and have two superimposed bearings (18, 19) with which loads from the web (4) are transferred to the uprights (2). The web further has outriggers (5) arranged on the brackets (8), a grating (6) that rests on the outriggers (5), and a railing (7), the railing uprights (22) of which are fastened to the outriggers (5). Via a first bearing (18) of the bracket (8), on the one hand, vertical forces and, on the other hand, horizontal forces directed parallel to the longitudinal axis of the outriggers (5) are transmitted to the uprights (2). Via a second bearing (19) of the bracket (8), which has an elastic damping element (21), only compressive forces directed parallel to the longitudinal axis of the outriggers (5) are transmitted. The second bearing (19) is arranged below the first bearing (18).The grate (6) rests on the outriggers (5) via elastic support elements (25).
