OPENING AND CLOSING ROOF STRUCTURE

Japanese Patent JP3205629

B2

PURPOSE: To lighten a movable shed structure body by forming a shed arranged at least on the lowest stage of a pair of right and left divided roof structure bodies in a string beam structure where a cable is used as a lower chord, and upward bending deformation is given to a top chord.
CONSTITUTION: The movable shed structure body 1 of an opening and closing type roof structure is provided with a pair of right and left divided roof structure bodies 6, which are composed of a lower stage shed 7 and an upper stage shed 8. The shed 7 applies a space truss structure beam 9 as main component, and has a top chord 10, whose lower face is provided with a plurality of string beam sections 11, and the adjacent string beam sections 11 are connected by a connecting member 12. Next, the beam section is formed in a string beam structure where the upper end of a plurality of compression members 13 is joined to the member 10, and a cable 14 is stretched from one end of the member 10 to its other end through the lower end of the member 13, and tensile force is given to the cable 14 to give upward bending deformation to the member 10. Thus a rational equilibrium system using the cable 14 can be obtained to lighten the structure body 1.
