Guard Rail Base With Cast-In Insert For Stable Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guard rail bases are difficult to position, prone to displacement, and costly to fabricate, making them undesirable for perimeter installations such as roofs.
Innovation Solution
A novel guard rail base design featuring an insert with a plate, tubes, handles, and an anchor, which allows for secure placement using a transporter, and a method involving pouring castable material into a form with the insert, inverting the form to embed the base, and sliding out a rod for removal, enabling easy handling and secure attachment of panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional guard rail bases are used, then they can provide basic structural support, but they are difficult to position and relatively easy to be pushed when fixed to panels
Solution Approach 1:
The base is divided into an upper base and a lower base that can be assembled together. The upper base contains positioning features that engage with corresponding features in the lower base, allowing for easy alignment and assembly while providing stable support that resists pushing forces.
Solution Approach 2:
The base includes pre-formed positioning elements and engagement features that are built into the structure during manufacturing. These preliminary features enable straightforward positioning and secure attachment without requiring complex adjustment or additional components during installation.
2Ease of manufacture
If traditional guard rail bases are used, then they can provide structural support, but they are relatively expensive to fabricate
Solution Approach 1:
Dividing the base into upper and lower sections allows for simplified manufacturing of each component using standard fabrication processes. This segmentation reduces overall fabrication complexity and cost while maintaining the structural integrity needed for guard rail support applications.
Solution Approach 2:
The base structure concentrates material and reinforcement only where structurally necessary - particularly in the engagement regions and load-bearing areas. This localized quality approach reduces overall material usage and fabrication cost while preserving essential strength and support capabilities.

AI summary
The top surface of an insert abuts with a form, with a tube extending into an aperture and sliding on a form post in the form. A rod inserted through the form, form post and tube holds the insert in place while castable material is poured in. The form is inverted with the guard rail base inside, the rod can be slid out of the form, and the form is removed. The handle is gripped by a claw on the obtuse angled chassis of a transporter. A handle on the chassis can be pushed to raise the guard rail base and to move the guard rail base on the surface by wheels. The guard rail base can be placed upon a pad having notches in its border.
