Temporary structures support concrete and workers.
Formwork moulds concrete and must resist pressure of fresh concrete (up to ρgh), be stable and tolerance-accurate; scaffolding provides working platforms and temporary support. Design for loads, bracing and safe stripping times. Failures cause serious accidents.
Slab formwork stays until concrete reaches 70% of design strength.
Formwork and scaffolding hold concrete and workers in place during construction, and their failure is one of the most serious site hazards.
Temporary structures support concrete and workers.
Formwork and scaffolding hold concrete and workers in place during construction, and their failure is one of the most serious site hazards.
Only when the concrete has gained enough strength, as shown by test results or maturity data, and the engineer has approved it.
A temporary support, often a steel post, that holds up the formwork and the wet concrete until the slab can carry its own load.
Typical applications include designing the formwork for a slab pour to carry the wet concrete load, erecting scaffolding for a façade repair with safe access and planning the removal of props to avoid early loading of new concrete.
Study "Construction equipment" first (topic 104 of 112 in Civil & Structural). It covers the groundwork this topic builds on.
Falsework design. Tie and bracing. Striking criteria.
Slab formwork stays until concrete reaches 70% of design strength.
The next topic is "Construction safety", which builds directly on this one.
It is classed as Advanced in Civil & Structural (topic 105 of 112). It is an advanced topic. It assumes you are comfortable with the intermediate topics in Civil & Structural.
