Structurally integrated accessible floor system

摘要

A floor system for a building includes prefabricated grid sections attached to framing members of the building and a plurality of panels mounted to the grid to form a structurally integrated floor. The panels are removable to provide access to space below the floor that would otherwise be inaccessible in a conventional floor. A subfloor deck below the floor separates one building story from another and encloses the space between the floor and the deck, which can be used for temporary and permanent installations including, for example, pipes for water, laboratory gases, and compressed air, and power, telephone, and data cables; and as a plenum for HVAC. Either or both of the floor and the subfloor deck can be attached to the building frame to function as a diaphragm. The floor system replaces conventional permanent structural floors and raised accessible flooring systems.

1. A floor section, comprising:
a plurality of grid members lying spaced-apart and parallel to a first horizontal axis, each of the plurality of grid members including:
first and second cold-formed steel beams lying parallel to each other and coupled together, the first and second beams forming a flat uppermost surface; anda flat plate lying in a horizontal plane and located over the flat uppermost surface formed by the first and second beams coupled together, the flat plate having a plurality of threaded apertures configured to receive respective fasteners; and a plurality of subfloor rails lying parallel to a second axis, perpendicular to the first axis, the plurality of subfloor rails being located below and rigidly and directly coupled to surfaces of the plurality of grid members, providing support for the plurality of grid members.
