Scaffolding products along with the development of the domestic construction industry grows and changes, scaffolding products are continually changing the current use of more frame scaffold, mobile scaffolding, ringlock scaffolding, cuplock scaffolding, etc. Each scaffold construction plan and requirements are different, here small make up with you analysis under the bowl of the scaffold construction plan and specifications.

1, the engineering general situation


This project is located in Qingdao city of hangzhou branch - anshan road, is hangzhou branch, Qingdao expressway project is an important part of Anshan road, is also the key to the whole expressway engineering and control engineering. Jiaozhou bay ring motorway Toll Gate bridge in the west, the east even liaoyang road, 32 across my section line viaduct, a total of eight league.


The engineering design of the speed of 60 km/h, bridge design load standard for city - A, earthquake-resistant standard is 6 degrees, according to the intensity of 7.The design reference period of 100 years.8 main girder scaffolding tube 24.5 meters, the main girder cross section for general cantilever structure, 2.75 meters on both sides of the cantilever.


Superstructure for prestressed concrete continuous box girder, a total of eight league 32 across 998 m (32 35 40 x 2 x 2 x 4 30 x 24), a total of 17615.40 m3 C55 concrete; Infrastructure for scaffolding tube pile foundation pile caps is round (end) pier, abutment one for U light abutment.


2, bowl timbering technology solutions


1) support structure design and stress check computation

And bowl support design and stress check calculate accurately a full framing the land mechanical book is checked. Support design should pass for approval, project technical officers and security officers and approved by the supervising agree.
