Abstract

The present invention relates to a mobile scaffold moving method and a moving device applied to the mobile scaffolding method for constructing the upper structure of the bridge by a span while moving the scaffold with a formwork without disassembly. Conventional mobile scaffolding has a structure in which the longitudinal and lateral movement of the scaffold is configured to move the scaffold in a sliding manner by supporting the supporting device of the sliding member type, and the sliding member for moving the scaffold in the longitudinal and transverse directions. Their configuration is difficult and difficult to process, and their own weight is heavy and manufacturing cost is high. In particular, longitudinal movement is carried out by a separate rope traction device, so the longitudinal movement speed is irregular and unstable, and simultaneous movement of front and rear scaffolds The interlocking control is very difficult, and the overall movement time is slow and the workmanship is increased.

The present invention provides a method for moving a mobile scaffold, comprising: a supporting means configured to support a lower portion of the scaffold in a rolling contact state, and a rotation capable of rotating a portion of the supporting means in a scaffold support device installed on each pier bracket. The scaffolding is carried out in the horizontal direction of the scaffold on the pier bracket by a moving cart comprising a longitudinal moving device having a driving means integrally and a rolling horizontal moving device for accommodating the longitudinal moving device. In the state supported by the supporting means, the transverse movement in the rolling method by the transverse movement device, and the longitudinal movement of the scaffold for the span movement is by rotating the rotary drive means provided in the longitudinal movement device directly to the scaffold The method of moving and moving the device for moving bridge scaffolds, which is characterized by the longitudinal movement of the rail and wheel system. It is characterized by the gongham.
