Large span enclosure

Abstract

Abstract PURPOSE: To facilitate regulation of bending of a frame by a method wherein the forward end of the extension end part of a large span frame body supported by columns and the base part of a column are coupled together with a tensile force by using a tension member. CONSTITUTION: A large span frame 1 is supported at columns 3, and the forward end of an extension end part 1a of the frame 1 and the base part of a column 3 are coupled together with a tensile force by using a tension member 5. The tensile force of the tension member 5 is regulated by the tension, in the direction of the upper end of the column 3, of the tension member 5 through a pulley 6. This constitution exerts a force in a down direction on the forward of the extension end part 1a and facilitates regulation of bending of the frame 1.
