体トラス。 The vertical and horizontal lower chord members 1 and 2 are intersected and interconnected to form a grid, and the vertical and horizontal lower chord members 1 and 2 extend alternately and in the same direction in both the vertical and horizontal directions. The vertical and horizontal upper chord members 3 and 4 are arranged on the inside and are connected to each other, and the lower chord member 1 and the upper chord member 3 are arranged on the inner side and are interposed in order between and connected to them. It consists of a flat and zigzag-shaped continuous diagonal member 5, and the lower chord member 1 and upper chord member 3 located inside have vertical portions 1a and 3a, and when viewed from the side,
The lower connecting portion 6 of the diagonal members 5 is formed in a substantially inverted trapezoidal shape, and the upper connecting portion 7 is formed in a substantially trapezoidal shape. At the same time, the substantially trapezoidal connecting portions 7 of adjacent diagonal members 5 are overlapped with each other via the vertical portions 3a of the upper chord members 3, and both front and rear ends of the connecting portions 6 and 7 are twisted to form a twisted portion 8. , 9 is formed.
