Modular Barricade Component with Reinforcement Truss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barricades are ineffective against vehicle-borne attacks due to weak structural components and fragile interconnections, which fail to halt vehicles carrying explosives.
Innovation Solution
A barricade component with an endless perimeter wall, reinforcement cage, and elongate trusses that extend between connecting lugs, along with a single connector pin for interconnecting multiple components, enhancing structural integrity and energy dissipation upon impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional barricade components are used, then the structure is simple and easy to manufacture, but the connection strength and ability to halt vehicles is insufficient
Solution Approach 1:
The barricade is divided into multiple modular components that can be interconnected. Each component has standardized connecting lugs that allow for assembly into larger barricade structures, maintaining ease of manufacture while improving overall strength through modular reinforcement elements.
Solution Approach 2:
The barricade component combines concrete with steel reinforcement bars and steel trusses to create a composite structure. The steel elements provide tensile strength and structural rigidity while the concrete provides compressive strength, resulting in a connection structure that can withstand vehicle impacts.
2Loss of energy
If traditional barricade components are used, then the manufacturing process is simple, but the energy dissipation capability upon impact is insufficient
Solution Approach 1:
Reinforcement bars and trusses are pre-installed within the concrete components during manufacturing. This preliminary placement of structural elements ensures that the energy dissipation capability is built into the component itself, rather than requiring complex post-assembly modifications.
Solution Approach 2:
The composite construction of concrete combined with steel reinforcement and truss elements creates a structure that dissipates impact energy through multiple mechanisms: concrete compression, steel yielding, and truss deformation. This approach achieves superior energy dissipation without significantly complicating the manufacturing process.
3Strength
If multiple connector elements are used for interconnection, then the connection strength is improved, but the device complexity and assembly difficulty increase
Solution Approach 1:
The connecting lugs are designed to integrate multiple functions into a single structural element. Each lug serves as both a structural reinforcement feature and a connection point for joining adjacent barricade components, eliminating the need for separate connector hardware and simplifying the overall assembly process.

AI summary
A barricade component comprises an endless perimeter wall defining a geometric shape in a front-to-back plane. At least two circumferentially spaced-apart connecting lugs are also provided on the perimeter wall which interconnect like or similar barricade components and these extend in an axial top-to-bottom direction. A reinforcement cage is within the perimeter wall and the lugs, and at least one elongate truss extends in a circumferential direction and an axial direction within the wall from one said lug to the other said lug. A method of interconnecting a plurality of said barricade components, and a method of forming such a barricade component are also provided.
