Pan

Definition

A pan is a form used to produce a cavity between joists in a one-way concrete joist system.

Purpose

Pans are used in concrete construction to create voids between joists, reducing the overall weight of the slab while maintaining structural integrity. This method is commonly used in building floors and roofs where a one-way joist system is specified.

Examples of Use

• Floor Systems: Used in multi-story buildings to construct floors with reduced weight.
• Roof Structures: Employed in the construction of flat roofs to create a lighter yet strong support system.
• Parking Garages: Implemented in the design of parking structures to efficiently support vehicular loads.

Related Terms

• Joist: A horizontal structural member used to support a floor or ceiling.
• Concrete Formwork: Temporary or permanent molds into which concrete is poured to form structural elements.
• One-Way Slab: A slab that is supported on two opposite sides and primarily carries load in one direction.

Notes

• Material: Pans can be made from various materials, including metal, plastic, or fiberglass, depending on the specific construction requirements.
• Reuse: Some pans are reusable, making them cost-effective for large construction projects.
