Senior rebar detailer Interview Questions and Answers

Spacer bars are used to maintain the correct spacing between rebar in concrete structures.

• Spacer bars are typically made of plastic, metal, or composite materials.

• They are placed at regular intervals along the length of the rebar to ensure proper spacing.

• Spacer bars help prevent rebar from touching each other or the formwork, which can lead to corrosion.

• Examples of spacer bars include plastic chairs, wheel spacers, and clip-on spacers.

Formsaver is used to connect rebar to formwork, while coupler is used to connect two rebars together.

• Formsaver is typically used in situations where the rebar needs to be connected to formwork, such as in concrete walls or columns.

• Couplers are used when two rebars need to be connected end-to-end, such as in long beams or slabs.

• Formsavers are often used for vertical applications, while couplers are more commonly used for horizontal applications.
