Reusable Steel Hoarding System for Construction Sites
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hoarding systems for building sites are typically non-reusable, leading to significant waste and increased costs due to the use of timber posts, concrete foundations, and labor-intensive installation processes.
Innovation Solution
A reusable hoarding system utilizing steel posts and floor plates secured to concrete blocks, eliminating the need for excavation and concrete curing, with components designed for easy assembly, disassembly, and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If timber posts with concrete foundations are used, then the hoarding provides stable support and barrier function, but the system becomes non-reusable and generates significant waste
Solution Approach 1:
The patent implements a reusable hoarding system where steel posts and floor plates are designed to be recovered and reused across multiple building sites. The modular components are easily dismantled and transported, eliminating the need to discard timber posts and concrete foundations after single use, thus resolving the contradiction between structural reliability and waste generation
Solution Approach 2:
The patent replaces the traditional timber and concrete mechanical system with a steel-based modular system that uses reusable components. This substitution maintains structural stability while enabling recovery and reuse, directly addressing the waste problem associated with conventional disposable hoarding systems
2Reliability
If excavation and concrete pouring are required for post installation, then the hoarding achieves secure anchoring, but the installation time and process complexity increase
Solution Approach 1:
The patent employs pre-assembled modular units with floor plates and steel posts designed for rapid connection without requiring on-site excavation or concrete pouring. The components are prepared in advance with connection mechanisms that enable quick assembly, thereby reducing installation time while maintaining anchoring security through the designed connection systems
Solution Approach 2:
The patent extracts and eliminates the time-consuming excavation and concrete pouring steps from the installation process. By using a modular steel system with direct connection mechanisms, the invention removes these intermediate steps while still achieving secure anchoring, thus resolving the contradiction between reliability and installation time
3Reliability
If plywood panels are nailed to timber rails, then the panels are securely attached, but the panels suffer damage and cannot be reused
Solution Approach 1:
The patent uses steel posts with channels instead of timber rails, and secures panels through the channel structure rather than nailing. This composite approach using steel framing with panel insertion or clipping mechanisms attaches panels securely without causing damage, enabling panel reuse and resolving the contradiction between attachment security and panel integrity
4Ease of manufacture
If conventional timber hoarding is used, then initial installation is straightforward, but the system cannot be reused and requires scrap disposal
Solution Approach 1:
The patent divides the hoarding system into modular segmented components (floor plates, steel posts, panels) that can be easily assembled and disassembled. This segmentation maintains installation simplicity while enabling reuse and reconfiguration at different sites, resolving the contradiction between ease of manufacture and adaptability for reuse

AI summary
A re-usable hoarding system (1) comprises a plurality of spaced-apart, steel floor plates (2) securable, in a releasable manner, to a support structure (5); a corresponding plurality of steel posts (9), each adapted to be releasably secured at a lower end thereof to one of the floor plates (2), with at least one upright channel (13) provided by each post (9); and at least one self-supporting timber panel (15), of such width that upright edges (14) of the panel (15) are locatable in opposed channels (13) defined by two adjacent posts (9).
