Temporary Centering

Definition

Temporary centering is support used during the construction process for the support of a masonry arch or a concrete slab, which is not permanent.

Purpose

The primary purpose of temporary centering is to provide stability and support to structural elements such as arches or slabs until the construction materials have gained sufficient strength to support themselves. It ensures the correct shape and position of the structure during the curing or setting phase.

Examples of Use

1. Masonry Arches: Temporary centering is used to hold the stones or bricks in place until the keystone is set and the arch becomes self-supporting.
2. Concrete Slabs: During the pouring and setting of concrete slabs, temporary centering holds the formwork and the concrete in place until it hardens.

Related Terms

• Formwork: Temporary or permanent molds into which concrete or similar materials are poured.
• Scaffolding: Temporary structures used to support work crews and materials to aid in construction.
• Shoring: Temporary support to maintain stability during construction or repair of structures.

Notes

• Removal: Temporary centering must be carefully removed once the structure has achieved the necessary strength to prevent damage.
• Design: The design and construction of temporary centering must consider the load and stresses it will bear during the construction process.
