Definitions

  • the Movable Scaffolding System (MSS) for bridge construction may offer advantages over conventional construction (Conventional Scaffolding), including creating minimal disturbance to surroundings, providing a more concentrated work area for superstructure assembly, and possibly increased worker safety given the improved erection environment.
  • MSS Movable Scaffolding System
  • Movable Scaffolding Systems are conceived to be used in the construction of cast in-situ concrete bridges and they are travelling steel structures supporting the formwork that gives shape to the bridge.
  • the MSS is built to be backed off from the hardened concrete, moved to a new position, and precisely adjusted for concreting the next span.
  • the Movable Scaffolding System was developed in the mid 1970's. The system has since been further developed and has become a very popular system for constructing bridges worldwide. The ability to adapt the MSS to different cross sections allows the contractor to use the equipment for different projects elsewhere.
  • the MSS consists of a support structure spanning between two piers from which formwork is either supported or suspended.
  • the inner formwork (core form) is collapsible and can run on a rail system to allow easy relocation to the next span.
  • the system is designed so that the outer formwork can be opened sufficiently to allow it to pass around the bridge columns during the launching process. After launching the formwork is closed again and after setting to the correct alignment, placement of reinforcement can start.
  • the MSS can be divided into two types, namely, (i) underlane (or underslung) and (ii) overlane (or overhead).
  • the underlane type of MSS has two parallel girders. which supports the formwork.
  • the overlane type of MSS has one or two main girders from which the formwork is suspended.
  • type of bridge deck e.g. single cell, twin cell, double T
  • height of columns e.g. single cell, twin cell, double T
  • NRS is the first in the world to develop the Self-launching MSS (SL-MSS) in order to to solve the problems related to the difficulties in handling pier support brackets over water as well as on high piers.
  • This system is able to transfer forward and mount the pier support brackets without any need of an independent crane.
  • the SL-MSS has been successfully used in the construction of several major bridge projects worldwide and is widely sought after due to its cost and operational efficiency.
  • the existing problems related to current MSS include requirement of long cycle time, inability to deliverable whole rebar cage simultaneously or all at once, requirement of several block-outs in the superstructure, requirement of hanging bars passing through the superstructure deck to support the formwork, requirement of other equipments necessary for relocation of the supports and, last but not least, the complexity of its operation as well as the labor intensive work.
  • This invention provides the new MSS with the self-launching system used for cast-in-situ bridges which can offer many cost-saving advantages to the bridge construction project.
  • FIGS. 1-A and 1 -B show General Arrangement: Elevation and Plan
  • FIGS. 2-A and 2 -B show Section A at Hanger Truss: Rebar cage installation & Concrete positions
  • FIGS. 3-A and 3 -B show Section A at Hanger Truss: Launching position at typical pier & portal pier
  • FIGS. 4-A , 4 -B and 4 -C Section B at Rear Support Rebar cage installation, concreting and launching positions

  • FIGS. 6-A and 6 -B show Section C at Front support: Launching position at typical pier & portal pier
  • FIGS. 7-A and 7 -B show Section D at Middle launching support: Launching and relocating positions
  • FIGS. 8-A and 8 -B show Section E at Front launching support: Launching and relocating positions
  • FIGS. 9-A and 9 -B show Launching sequence: Stage 1 and 2
  • FIGS. 10-A and 10 -B show Launching sequence: Stage 3 and 4
  • the self-launching movable scaffolding system (SL-MSS) according to this invention comprises of
  • the assembling and erecting sequence of the said SL-MSS can be described as the following:
  • the launching sequence of the said SL-MSS comprises of the concreting and launching stages as the following:
  • Stage 1 (as shown in FIG. 9A )
  • Stage 2 (as shown in FIG. 9B )
  • Stage 3 (as shown in FIG. 10A )
  • Stage 4 (as shown FIG. 10B )
  • the dismantling process of the said SL-MSS can be described as the following; Process of this operation is depended on the actual condition at site and varied from job to job. A careful planning and drawings should be done before actual dismantling begins.
