Completed falsework: Decking and some formwork has been added. The illustrations are of modern pipe-column falsework, used to support the formwork for a post-tensioned reinforced concrete flyover connector for the eastern span replacement of the San Francisco-Oakland Bay Bridge. When the supports are complete, wood beams and plywood or reusable ...
Shoring is designed to prevent collapse where shielding is only designed to protect workers when collapses occur. Concrete-structure and stone-building shoring, in these cases also referred to as falsework, provides temporary support until the concrete becomes hard and achieves the desired strength to support loads.
It expanded rapidly in formwork and scaffolding under GKN ownership in the end of the 1980s. [2] In June 2000, GKN Kwikform merged with RMD (Rapid Metal Developments, established in 1948), the formwork and scaffolding unit of RM Douglas (part of Tilbury Douglas), to form RMD Kwikform. [3] [1] Tilbury Douglas renamed itself Interserve in 2001. [4]

Stretchers and headers are laid with alternating courses aligned to one another. American common bond is similar to the English bond but with one course of headers for every six stretcher courses. English cross bond has courses of stretchers and headers, but with the alternating stretcher courses offset by half a brick.
Scaffolding for rehabilitation in Madrid, Spain [1] Scaffolding for renovation on the Virgin Mary statue, Santiago de Chile, Chile.. Scaffolding, also called scaffold or staging, [2] is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other human-made structures.
Control of the flexibly formed beam cross section is key to achieving low-material use design. The basic assumption is that a sheet of flexible permeable fabric is held in a system of falsework before reinforcement and concrete are added. By varying the geometry of the fabric mould with distance along the beam, the optimised shape is created.
In the self-anchored suspension bridge, however, the cable must be anchored to the bridge deck, which has yet to be built and will not bear its own weight; ergo, falsework must be employed until the final method of suspension is possible. The cables apply strong axial forces onto the bridge girders, which may require strengthening.
