Abstract
A portable, rapidly erected fabric covered building-type structure has a plurality of articulated arch frames which may be hoisted from the ground to extend transversely in longitudinally spaced vertical planes. Spreaders rigidly connect the arch frames. Individual rectangular fabric sections extend transversely between corresponding adjacent pairs of the arch frames to provide an interior sheltered from the outside environment. The side edges of the fabric sections are connected to the rails of removable ladder-like mechanisms carried by the frames for tensioning the sections across their widths. The ends of the fabric sections are also pulled downwardly at the sides of the building by other mechanisms for tensioning the fabric sections lengthwise.
