What is Overview about Movable Scaffolding System?
MSS(Movable Scafflding System) is a kind of construction equipment for cast-in-place concrete girder by use of self formwork and loading bearing longitudinal girder. The technology was originated in west Europe in 1950s, introduced into Japan and America in 1970s and now prevails all over the world as one main way to construct bridge.

What are Construction Precautions for MSS660 Movable Scaffolding System?
Movable scaffolding system
1 Walkway for steel box girder of formwork at two sides is reinforced concrete walkway which not only bears load from workers, but also work as weights, 22t at each side, counterweights are set uniformly along 36m steel box girder
What are Quality Warranty Measures for MSS660 Movable Scaffolding System?
Quality warranty check for MSS660 movable scaffolding system ensures the normal working of equipment after leaving factory, thus provide a guarantee for buyer”s convenience and save maintenance cost for sellers in the future, save unnecessary troubles for both buyers and sellers.
What is Construction Period Analysis for MSS660 Movable Scaffolding System?
Before we begin to use movable scaffolding system, we should keep in mind the construction period to construct one span girder, so that the construction? process can be ensured.
HZQ50-160t
Construction period analysis for MSS660 movable scaffolding system is as followings:
1. Install reinforcing steel bar of bottom and web plate, lay pre-stressing hole and put in pre-stressed tendon. (1.5 days)
2. Install scattered internal formwork ?????(1 day)
3. Install reinforcing steel bar of top plate?? (1day)
4. Pour and maintain concrete (internal formwork loosing is included to reduce friction loss for pre-stressing tension)? ?????????????????(4 days)
5. Stretch-draw pre-stressed tendon. ???????(0.5 days)
6. Drop formwork to remove the connection between bottom formwork truss girder and bottom formwork connection bolts at the part of bridge axis (bottom formwork centre joint). Move laterally to separate the formwork, move longitudinally to cross piers, move laterally to close the formwork, lay bottom die and end die at pier top. (1.5 days)
10 days in total. Usually it is more appropriate to construct one span for 10 days in the normal construction, first span installation and commissioning could be finished in 1 month, the first two spans concrete girders can be arranged to produce according to the schedule 15 days per span because workers are not familiar with the condition.
How to Install and Check Structure of MSS660 Movable Scaffolding System?
Installation steps:
1. Install support frame, main girder, guide beam
MSS660 movable scaffolding system
1.1 Set up installation support. Level field between 14# abutment and J1 pier according to Installation Steps Drawing, and set up installation support and temporary pier for steel box girders and guide beam connection parts. Support height should meet the demand that steel box girder bottom part should be 5cm higher than support roller top surface. Built by steel pipes in the worksite, the support should meet the needs of bearing capacity in the installation process and ensure enough bearing capacity settling volume ?1cm.
What are Construction Steps and Precautions for Movable Scaffolding System?
Movable scaffolding system
Construction steps and precautions
1. Construction steps
1.1 Movable scaffolding system main girder falls down, be divided, moves laterally
1.1.1 Remove suspender of rear anchoring device
1.1.2 Remove home-made bulk formwork at the top of pier;
1.1.3 Meanwhile steel box girder support jacks fall. The formwork separates from poured concrete girder, steel box girder is supported on support roller of longitudinal moving gearbox; remove formwork at centerline of MSS and connection bolts of cross girder. Check whether connection between formwork lateral moving device and left, right parts of formwork is been removed totally, little lateral moving divides MSS into two parts.
What are Functions of Main Structure of Movable Scaffolding System?
?Structures and main functions
Upstroke movable scaffolding system
General dimension in working condition length 70m, width 19m, height 12m, from upper to bottom part, ZZHZ movable scaffolding system is made up of support frame, support gearbox, front and rear guide beam, main girder and lateral connection part, bottom die, side die and rear anchoring beam, anti-typhoon device, hydraulic system and walkway (stairs, platform) and other parts. Realize functions of automatic jacking of hydraulic system, lateral moving and longitudinal moving to cross piers. The complete machine can meet two-way construction demands: moving forward and moving backward construction.
