Slip Form Assembly Segmentation for Concrete Wall Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction systems for concrete structures, such as tilt-up panels and vertical form systems, are costly and sensitive to weather, making them inefficient for constructing small to midsize structures, and require high lifting capacity and additional work platforms, which increases costs and downtime.
Innovation Solution
A slip form assembly system comprising a lifting pole with inner and outer forms that are slidably coupled and moveable along the pole, allowing for independent lifting and simultaneous pouring, molding, and casting of concrete walls, reducing the load on lifting mechanisms and enabling continuous construction processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If tilt-up panels are used for constructing concrete walls, then construction speed is improved, but construction cost increases and weather sensitivity worsens
Solution Approach 1:
The construction system divides the wall into multiple segments that can be formed independently using separate slip form assemblies. Each assembly can operate autonomously, allowing parallel construction of different wall sections, which maintains high productivity while reducing overall cost through modular, scalable deployment
2Strength
If vertical form systems are used for pouring concrete walls, then wall strength is improved, but lifting capacity requirements increase and device complexity worsens
Solution Approach 1:
The form system is segmented into multiple independent slip form assemblies, each capable of supporting its own concrete load. This distributes the lifting capacity requirements across multiple smaller units rather than requiring one large complex system, while maintaining wall strength through proper reinforcement integration
Solution Approach 2:
The slip form assemblies are designed to be dynamically adjustable and movable along the completed wall sections. This allows the forms to slide upward as concrete hardens, providing continuous support during the critical strength-gaining period while simplifying the overall system through reusable, repositionable components
3Productivity
If multiple slip form assemblies are used for simultaneous pouring, then productivity is improved, but coordination complexity increases
Solution Approach 1:
All slip form assemblies use standardized, interchangeable components and follow uniform operational procedures. This universality allows multiple assemblies to operate simultaneously with minimal coordination overhead, as each unit is a replica of the others and can be managed through the same control protocols

AI summary
A slip form assembly includes a lifting pole extending in a longitudinal direction and an inner form slidably coupled to the lifting pole and extending in a lengthwise direction perpendicular to the longitudinal direction between a first end and a second end. The first end is configured for end-to-end contact with an adjacent end of an adjacent inner form. An outer form is slidably coupled to the lifting pole opposite the inner form and defines a cavity for casting a portion of a wall therebetween. The outer form extends parallel to the inner form between a first end and a second end. The first end of the outer form is configured for end-to-end contact with an adjacent end of an adjacent outer form. The inner form and outer form are moveable along the lifting pole longitudinally relative to the respective ends of the adjacent inner form and outer form.
