Immersed tube prefabricated opposite-pulling outer side formwork truss structure
An immersed tube prefabricated opposite-pulling outer side formwork truss structure comprises a truss body and a longitudinal connecting assembly, the truss body comprises a main body inner chord member, a main body outer chord member, a main body horizontal web member and a main body inclined web member, and the main body inner chord member is connected with two reinforcing rib plates in a welded mode; the upper side and the lower side of each reinforcing rib plate are connected with the inner ends of every two adjacent main body diagonal web members in a welded mode, each reinforcing rib plate is connected with the inner end of the corresponding main body horizontal web member in a welded mode, and the two reinforcing rib plates are connected with the steel pull rods. According to the embodiment of the invention, the steel pull rod is connected to the reinforcing rib plate mounted on the main body inner chord member, and the reinforcing rib plate is connected with the two main body diagonal web members and the main body horizontal web member, so that a force transmission path is shortened, and the web members are prevented from being pressed and unstable; the web members are connected to the two sides of the reinforcing rib plates serving as steel tie rod anchor points, the span is reduced, the local bending moment is reduced, the steel bar system conversion load generated by the top truss is borne by adopting a small-steel-amount side formwork truss structure, the concrete side pressure can also be borne, and the purpose of reducing the number of steel tie rods is achieved.
一种沉管预制对拉外侧模板桁架结构，包括桁架主体和纵向连接组件，桁架主体包括主体内弦杆、主体外弦杆、主体水平腹杆和主体斜腹杆，主体内弦杆均焊接连接有两个加强肋板，加强肋板的上下两侧分别焊接连接相邻两个主体斜腹杆的内端，加强肋板与对应的一个主体水平腹杆的内端焊接连接，两个加强肋板均连接钢拉杆。本发明实施例中将钢拉杆连接到主体内弦杆安装的加强肋板上，加强肋板连接两个主体斜腹杆以及一个主体水平腹杆，缩短了传力路径，避免腹杆受压失稳；作为钢拉杆锚点的加强肋板两侧连接腹杆，减小跨度，减小局部弯矩，采用小钢量，侧模桁架结构承担顶部桁架产生的钢筋体系转换荷载，又可以承受混凝土侧压力，达到减少钢拉杆个数的目的。
