Abstract

The invention discloses a fold line type single-layered cylindrical latticed shell structure. The fold line type single-layered cylindrical latticed shell structure comprises a plurality of first steel archs and a plurality of second steel archs, and is characterized in that the plane where the first steel archs are arranged is parallel to the plane where the second steel arch centers are arranged; the direction vertical to the plane where the first steel archs are arranged or the plane where the second steel archs are arranged is a length direction; the first steel archs and the second steel archs are alternatively arranged at equal distances along the length direction; the heights of the plurality of first steel archs are the same; the heights of the plurality of second steel archs are the same and are lower than the heights of the first steel archs; a plurality of reinforcing ribs are welded between each first steel arch and the adjacent second steel arch. The fold line type single-layered cylindrical latticed shell structure with high flexural rigidity and high stable carrying capacity is realized.

Description

technical field

[0001] The invention belongs to the field of space structure engineering, and in particular relates to a broken-line single-layer cylindrical reticulated shell structure, which is mainly used in structures requiring large space and long-span roofs such as gymnasiums, exhibition halls, and waiting halls. Background technique

[0002] The single-layer cylindrical reticulated shell structure is one of the most commonly used space grid structures at present. It has the advantages of beautiful appearance, few components, reasonable force, low steel consumption, and transparent vision.

[0003] The main forms of single-layer cylindrical reticulated shell structure are: single-slope type, Fopper type, double-slope type, joint square type, three-way grid type, and Pozi grid type. When the single-slope bar type single-layer cylindrical reticulated shell structure is manufactured, firstly, the arc length is divided along the curve, and the parallel longitudinal straigh...
