Climbing Formwork System with Hydraulic Track Columns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional construction methods for high-rise buildings, such as climbing formwork devices, face limitations in efficiently covering multiple floors and ensuring safety, as they often require external fulcrums and have restricted coverage, leading to inefficiencies and safety concerns during construction.
Innovation Solution
A construction equipment system comprising hanging pedestals, sleeve frames, hydraulic cylinders, upper and lower reversing boxes, and track columns, which allows for a suspended platform to lift formworks vertically and horizontally, integrating a hanger system and awning device, enabling simultaneous construction and protection from weather, with a 'two-in-one' design for simplified lifting and extended coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional climbing formwork devices are used with external fulcrums, then the structure can support formworks and climb together, but the external facade frame body only covers two and a half floors
Solution Approach 1:
The system divides the climbing function into separate components: the hanging pedestal remains fixed on the shear wall, while the track column and integrated platform can be lifted independently to different heights, allowing different sections to cover different floor ranges simultaneously
Solution Approach 2:
The system adds vertical dimension flexibility by allowing the track column to be lifted to different heights along the hanging pedestal, enabling the platform to cover multiple floors (five and a half floors) beyond the traditional two and a half floor limitation
2Area of stationary object
If traditional attached lifting scaffold is used, then the climbing frame can cover four and a half floors, but it cannot carry formwork to climb up
Solution Approach 1:
The system merges the formwork carrying function with the climbing function by integrating the formwork suspension system directly onto the track column and platform structure, allowing the same structure to both climb and carry formworks simultaneously
Solution Approach 2:
The integrated platform serves multiple functions: it acts as the climbing carrier, supports formworks for construction, provides an aerial work platform for operations, and enables material distribution, replacing the need for separate dedicated climbing frame and formwork systems
3Device complexity
If external wall external fulcrums are used for climbing formwork, then the structure is simple with small oil cylinder, but the lifting force is less than 20t within a stroke of 20 cm
Solution Approach 1:
The system uses hydraulic cylinders with substantially larger lifting capacity than traditional small oil cylinders, enabling the platform to lift heavy formworks and construction materials while maintaining structural simplicity through standardized hydraulic components
Solution Approach 2:
The system changes the stroke parameter of the hydraulic cylinder from the traditional 20 cm to a substantially larger stroke, enabling the platform to lift the integrated platform, formworks, and construction materials simultaneously with sufficient force and travel distance
4Productivity
If manual labor is used for construction operations, then flexibility is maintained, but construction period is extended and efficiency is reduced
Solution Approach 1:
The system enables self-service construction operations through the aerial work platform, which provides direct access to construction areas for material distribution and operations, reducing the need for manual material handling and extending working hours beyond traditional limitations
Solution Approach 2:
The system enables continuous construction operations by providing stable aerial access and material distribution capabilities that allow work to proceed without interruption, supporting extended operating hours including nighttime and weekend construction to shorten the overall construction period

AI summary
A construction building equipment includes hanging pedestals, sleeve frames, hydraulic cylinders, upper reversing boxes, lower reversing boxes and track columns. The multiple hanging pedestals are fixed on an outer side of a shear wall of an external wall. The sleeve frames and the track columns are clamped on the hanging pedestals. The sleeve frames are clamped on outer sides of the track columns. The lower reversing boxes are fixed at upper ends of the sleeve frames. The hydraulic cylinders are connected with the upper reversing boxes and the lower reversing boxes. Side surfaces of the track columns are provided with pane holes for cooperative climbing of the upper reversing boxes and the lower reversing boxes. Upper ends of the track columns are fixedly connected with a top platform. Hangers and formworks are suspended on the top platform through booms.
