Climbing Formwork Elevator System for Upper Floor Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transporting personnel and material in a building under construction, especially when using a climbing formwork device, are inefficient and hinder construction work due to the need for frequent adjustments and the inability to reach uppermost regions effectively, leading to strenuous and time-consuming access via staircases and impractical material transport.
Innovation Solution
A method involving an elevator system with a mechanical platform that adjusts to increasing building height, combined with a secondary construction elevator installed in a separate or adjacent elevator shaft, allowing vertical transport to the climbing formwork platform, enabling convenient and time-saving movement of personnel and material without obstructing the climbing formwork device's operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an elevator system is installed in an elevator shaft that grows with the building height, then the elevator can serve lower floors during construction, but the top floor level reachable by the elevator may be up to 30m below the highest working level of the construction site
Solution Approach 1:
The transport system is divided into two independent elevator systems: a first elevator system in a first shaft for serving lower floors, and a second elevator system in a second shaft for serving uppermost floors. This segmentation allows each system to operate independently at its optimal level without interfering with the other, resolving the contradiction between adaptability to building height and ease of access to upper floors.
Solution Approach 2:
The first elevator system acts as an intermediary that transports personnel and material to an intermediate transfer floor, where they then transfer to the second elevator system for final delivery to the uppermost working levels. This intermediary approach enables the first system to adapt to building height while the second system provides direct access to upper floors.
2Adaptability or versatility
If a staircase is attached to the climbing formwork platform to bridge the vertical distance, then access to the climbing formwork platform becomes possible, but access becomes very strenuous and time-consuming for construction personnel and material transport becomes practically impossible
Solution Approach 1:
The manual mechanical system (staircase) is replaced with a motorized elevator system (second elevator system) that provides automated vertical transport. This substitution eliminates the strenuous manual climbing while enabling efficient material and personnel transport to the climbing formwork platform, simultaneously improving adaptability and productivity.
3Adaptability or versatility
If the mechanical platform and drive machine support and drive the elevator car and counterweight, then the elevator system can be adjusted to building height, but the mechanical platform and associated components take up a relatively large space above the highest car position
Solution Approach 1:
The elevator system is segmented into two separate systems in two separate shafts. The first elevator system handles the mechanical platform and drive machine for lower floor service, while the second elevator system serves uppermost floors. This segmentation distributes the space requirements and allows each system to be optimized for its specific operational range, reducing the overall space occupation problem.
4Device complexity
If the elevator system is adjusted only once more when the building has grown by the height of several floors, then the adjustment frequency is reduced, but the top floor level reachable by the elevator becomes temporarily up to 30m below the highest working level
Solution Approach 1:
The elevator service is segmented into two zones: lower floors served by the first elevator system and uppermost floors served by the second elevator system. This allows the first system to be adjusted less frequently while the second system continuously serves the uppermost working levels, eliminating the time delay that would otherwise occur during adjustment periods.
Solution Approach 2:
The second elevator system is preliminarily positioned to serve the uppermost floors before the first elevator system needs adjustment. This preliminary arrangement ensures that even when the first system is not adjusted frequently, personnel and material can still access the uppermost working levels through the second system, preventing time delays.

AI summary
A method and construction site device for vertical transportation during a building construction phase include a climbing formwork platform arranged in a currently uppermost region of the building for concreting at least part of the building core, an elevator car intermittently adjusted to a current building height in a first elevator shaft by hoisting a mechanical platform to a higher level and fixing it there, a construction elevator temporarily installed in a second elevator shaft and attached to the climbing formwork platform with a construction elevator car vertically movable in a construction elevator frame, and wherein people and/or material are transported to a floor associated with an access opening of the construction elevator by the elevator system and then are transported from this floor to a floor situated in the currently uppermost region of the building or to the climbing formwork platform by the construction elevator.
