Bailey truss and supporting structure
The invention relates to the technical field of bailey trusses, in particular to a bailey truss and a supporting structure, the bailey truss comprises an upper chord member, a lower chord member and a connecting assembly, the connecting assembly comprises a vertical web member, an inclined web member and a gusset plate, the upper chord member and the lower chord member are formed by combining two No.14 steel channels back to back, the vertical web member is welded to the inner side of the upper chord member and the inner side of the lower chord member through a rectangular pipe of 80 mm * 60 mm * 5 mm, and the gusset plate is welded to the outer side of the upper chord member and the inner side of the lower chord member. The diagonal web members are welded among the plurality of vertical web members, the diagonal web members are also 80 mm * 60 mm * 5 mm rectangular pipes, the size of the Bailey truss is larger than that of a domestic 321 type Bailey piece, under the same construction condition, the use amount of the Bailey truss is reduced, the construction period is shortened, the material leasing cost and the mounting and dismounting cost are reduced, meanwhile, the use amount of needed accessories such as Bailey pins and supporting frames is reduced, and the cost is reduced. The material strength of the Bailey trusses is larger than that of domestic 321 type Bailey pieces, the longitudinal and transverse distance between the spliced trusses is increased, the material consumption is reduced, the mounting, dismounting and hoisting times are reduced, the construction efficiency is improved, and the construction risk is reduced.
本发明涉及贝雷桁架技术领域，具体涉及一种贝雷桁架及支撑结构，包括上弦杆、下弦杆和连接组件，连接组件包括竖腹杆、斜腹杆和节点板，上弦杆和下弦杆由两根14号槽钢背靠背组合而成，竖腹杆由80mm×60mm×5mm的矩形管焊接在上弦杆、下弦杆内侧，多个竖腹杆之间焊接斜腹杆，斜腹杆也是80mm×60mm×5mm的矩形管，贝雷桁架尺寸均比国产321型贝雷片要大，在同等施工条件下，贝雷桁架的使用量将减少，进而缩短工期、材料租赁费用及安拆费用，同时其需要的配件，如贝雷销，支撑架等，都减少用量，贝雷桁架的材料强度比国产321型贝雷片要大，其拼接的桁架纵横间距增大，材料用量减少，安拆吊装次数减少，提升施工效率，降低施工风险。
