Floor assembly

摘要

A method of assembling a floor by assembling a frame that has joist extending from at least one frame-edge channel fixed at a first edge of the frame to an opposing edge of the frame, each channel has an upright web. The frame edge-channel is fastened between a pair of columns to support the first edge of the frame. The opposing edge of the frame edge-channel member is supported whereby the each frame edge member is fixed to a reinforcing channel to form a composite beam spanning between the columns. The beam has an I shaped cross section in which the webs of each frame edge channel and reinforcing channel are substantially parallel and each composite beam and joist has the same depth and provides substantially parallel upper and lower faces for receiving the ceiling and floor liners respectively.
