Antiperforation EPS Panel with Embedded Steel Box Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reinforced concrete products are prone to cracking under tensile stress and shear, necessitating reinforcement with steel elements to manage stress distribution, while existing building panels lack comprehensive anti-perforation and anti-breaking characteristics.
Innovation Solution
A prefabricated building panel composed of high-density sintered expanded polystyrene with embedded steel box-shaped structures, featuring alternating empty and full fields, provides enhanced resistance to perforation and breaking while maintaining lightness, similar to reinforced concrete structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If reinforced concrete is used to resist tensile stress and shear, then strength is improved, but weight increases
Solution Approach 1:
The patent combines sintered expanded polystyrene (providing lightness and compression resistance) with steel reinforcement elements (providing tensile and shear resistance) to create a composite building product that achieves the strength of reinforced concrete with significantly reduced weight
Solution Approach 2:
The steel reinforcement is strategically positioned in specific areas where tensile and shear stresses occur, rather than uniformly distributing material throughout the entire structure, optimizing strength while minimizing weight
2Ease of manufacture
If conventional building panels are used, then ease of manufacture is improved, but anti-perforation and anti-breaking characteristics are insufficient
Solution Approach 1:
The panel combines sintered expanded polystyrene with embedded steel elements (such as steel wires, meshes, or cage structures) to simultaneously achieve ease of manufacture through modular construction and superior anti-perforation and anti-breaking characteristics from the steel reinforcement
Solution Approach 2:
The steel reinforcement elements are embedded within the sintered expanded polystyrene matrix, with the steel components nested inside the polymeric mass, creating a integrated structure where the steel provides protective characteristics while the polystyrene provides structural bulk
3Strength
If steel reinforcement is added to sintered expanded polystyrene, then strength is improved, but device complexity increases
Solution Approach 1:
The steel reinforcement is divided into discrete elements (wires, meshes, or cage segments) that are independently positioned and then embedded in the sintered polystyrene, simplifying the assembly process and reducing manufacturing complexity while maintaining structural integrity

AI summary
An antiperforation building panel structure, particularly made of sintered expanded polystyrene (eps), includes a composite complex structure having embedded, in the sintered expanded polymeric mass, preferably of the high density type, a steel box-shaped structure with larger faces divided into first fields having larger openings therein and second fields having smaller fissures therein, the first and the second fields being arranged in positions that are inversely symmetric on the two faces, so that each first field on one face corresponds to a second field on the other face and vice versa.
