Firestop Platform for Corrugated Sheet Metal Penetrations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming through-penetrations in corrugated sheet metal formworks with alternating valley and peak regions are difficult to implement and limit positioning flexibility, potentially compromising the structural integrity of the formwork.
Innovation Solution
A pre-installation system comprising a platform, block-out component, and lead-sleeve is used to create a concrete-free area, allowing for flexible and efficient formation of through-penetrations by coupling the platform to the sheet metal, pouring concrete around it, and then using a cutting tool to remove sections of the sheet metal after it has solidified.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If through-penetrations are formed by drilling holes through poured concrete after concrete has been formed, then through-penetrations can be created, but the structural integrity of the formwork is compromised and positioning flexibility is limited
Solution Approach 1:
The platform is installed on the formwork before concrete is poured, creating a predetermined location for the through-penetration. This preliminary positioning allows the formwork to maintain its structural integrity during concrete pouring, while still enabling easy creation of through-penetrations afterward by removing the platform and forming openings at the pre-positioned locations.
2Adaptability or versatility
If through-penetrations are formed by positioning forming devices before concrete is poured, then positioning flexibility is improved, but the complexity of implementation increases
Solution Approach 1:
The system is divided into separate functional components: a platform that provides positioning flexibility, a block-out component that prevents concrete intrusion, and a lead-sleeve that guides the cutting tool. This segmentation allows each component to perform its specific function independently, simplifying the overall implementation while maintaining positioning flexibility through the platform's ability to be positioned at various locations.
3Ease of manufacture
If space retainers are mounted in the formwork to provide concrete-free space, then through-penetrations can be created, but positioning flexibility through the formwork is limited
Solution Approach 1:
The platform serves multiple functions: it positions the through-penetration location, supports the block-out component to prevent concrete intrusion, and provides a mounting surface for the lead-sleeve. This multi-functionality eliminates the need for separate space retainers, thereby maintaining ease of creating through-penetrations while significantly improving positioning flexibility as the platform can be positioned anywhere on the formwork.

AI summary
A method includes coupling a platform to a sheet metal having alternating peaks and Valleys. The platform includes a block-out component configured to conform to a valley of the sheet metal. The method further includes coupling a lead-sleeve to a mounting region of the platform. The method further includes pouring concrete around the platform and lead-sleeve, where the block-out component blocks a flow of the concrete from below the platform. The method also includes inserting a cutting tool through the lead-sleeve to remove one or more portions of the sheet metal to form a through-penetration.
