Attachment Sheath for Formwork Wall Guardrail Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guardrail installation methods require prior installation of sheaths on structures, necessitating manual intervention and extending construction time, especially when vertical walls are involved without a horizontal concrete structure.
Innovation Solution
Integration of a grip sleeve with a rectilinear structure and cooperation interface into the formwork wall structure, allowing for direct attachment of guardrails to vertical walls, using a binder layer and strategically positioned support points for stability and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sheaths are manually installed on structures before guardrail assembly, then guardrails can be securely positioned, but construction time increases and manual intervention is required
Solution Approach 1:
The sheathes are pre-installed into the formwork during the concrete pouring process, so that by the time the formwork is removed, the sheathes are already in position and ready to receive guardrail posts. This preliminary action eliminates the need for separate manual installation of sheathes after formwork removal, thereby reducing construction time while maintaining secure guardrail positioning.
2Ease of manufacture
If sheaths are integrated into horizontal concrete slabs, then manual installation is eliminated, but this solution cannot be applied to vertical walls without horizontal concrete structures
Solution Approach 1:
The invention adapts the sheath integration concept to work with both horizontal concrete slabs and vertical formwork walls. By designing the sheathes to be embedded directly into the formwork structure itself, the solution becomes universally applicable to different construction scenarios (horizontal and vertical), eliminating the limitation of only working with horizontal concrete structures.
3Manufacturing precision
If dedicated workforce is allocated for sheath installation, then proper positioning is ensured, but labor requirements and intervention time increase
Solution Approach 1:
The formwork structure itself serves the dual function of both supporting the concrete pour and providing the mounting substrate for the sheathes. Workers installing the formwork automatically perform the sheath installation as part of the formwork assembly process, eliminating the need for a separate dedicated workforce for sheath installation while maintaining proper positioning accuracy.
