Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-climbing perimetric protection systems for construction are not reliable, easy to handle, or cost-effective, particularly when used in conjunction with self-climbing formwork systems for tall buildings, as they often require complex crane operations and are not adaptable to varying building geometries.
Innovation Solution
A self-climbing perimetric protection system comprising modular masts with U-shaped channel irons, anchored by a guiding head with mobile claws and a bearing rocker, allowing vertical movement and horizontal force transmission, with adaptable configurations for rigid or articulated masts to suit different building geometries, and a self-climbing device with hydraulic cylinders for independent hoisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If perimetric protection systems are made self-climbing to enable independent lifting, then safety is improved by eliminating the need for workers in dangerous positions and productivity is improved by freeing up crane capacity, but device complexity increases due to the need for integrated hoisting mechanisms
Solution Approach 1:
The perimetric protection system is equipped with self-climbing capabilities through integrated hoisting mechanisms that enable the protection structure to lift itself independently. The system includes hoisting devices with winches or motors mounted on the protection structure, which can autonomously raise the protection along the building framework without requiring external crane assistance or worker intervention in dangerous positions.
Solution Approach 2:
The perimetric protection system is divided into modular sections or panels that can be independently assembled and hoisted. Each module contains its own support elements, protection panels, and hoisting mechanisms, allowing for staged installation and independent operation of each segment, thereby reducing overall system complexity while maintaining safety.

3Device complexity
If traditional perimetric protection systems are used requiring crane hoisting, then device complexity is reduced, but productivity deteriorates due to crane occupancy time and safety deteriorates due to workers in dangerous positions

Implementation Method 1
a bearing rocker with a front part adjacent to the mast, an intermediate part traversed by a horizontal rotation shaft and a rear part, the bearing rocker being rotational in a vertical plane between a working position in which said front part supports a support element and a release position in which it is distanced from the mast to allow at least one of the support elements to pass during the hoisting process
