Lifting platform for square pier

By using standard flaps to cover the work gaps and 'well'-shaped support units to stabilize the lifting frame during slipform construction, the problems of workers stepping into empty spaces and the lifting frame shifting during slipform construction were solved, thus improving construction safety and efficiency.

AI Technical Summary

Technical Problem

In slipform construction, the gap between the operating platform and the formwork can cause workers to slip and fall, posing a safety hazard. Furthermore, existing technologies struggle to effectively control the verticality and offset of the lifting frame, impacting construction safety and efficiency.

Method used

A lifting platform suitable for square piers is adopted, including a lifting frame, ring beam and operating platform. The working gap is covered by a standard flap. The support unit is a 'well' shaped structure. The lifting frame is stabilized by telescopic drive and adjustment parts. The verticality of the template is ensured by the combination of reinforcement and horizontal connectors.

Benefits of technology

It effectively prevents workers from falling into the air, ensuring construction safety, maintaining the verticality of the lifting frame, reducing deviation, improving construction efficiency and safety, reducing formwork deformation, and shortening construction time.

Abstract

This invention relates to the field of lifting platforms, and discloses a lifting platform suitable for square piers. The platform includes a lifting frame, a ring beam, and an operating platform connected in sequence. The lifting frame comprises several lifting units and horizontally arranged elongated support units. The lower ends of the lifting units are pre-embedded in the already cast section of the pier. The lifting units and support units are connected, and the support units are connected to the ring beam. A walkway is provided between the ring beam and the pier, leaving an operating gap covered by the walkway. The walkway includes several standard flaps, each hinged at one end to the ring beam, allowing for controllable coverage of the operating gap.
