Double-layer steel structure bridge auxiliary truss trial splicing method
The invention discloses a double-layer steel structure bridge auxiliary truss trial splicing method, which belongs to the field of steel structure bridges, and is characterized by comprising the following steps of S1, building a jig frame; S2, assembling main truss pieces, and sequentially assembling upper chords, lower chords and web members till all main truss piece rod pieces of the round are assembled; S3, assembling the upper chord side longitudinal beams and the auxiliary truss inclined rods, and assembling the upper chord side longitudinal beams and the auxiliary truss inclined rods insequence till all sections of the round are assembled; and S4, performing hole group matched drilling, specifically, drilling upper chord edge longitudinal beam hole groups through auxiliary truss inclined rod hole groups in a matched mode, drilling upper chord edge main longitudinal beam stiffening plate hole groups and connecting plate hole groups through standard splicing plates in a matched mode, and completing drilling before trial splicing through a first hole method. By the adoption of the double-layer steel structure bridge auxiliary truss trial splicing method, the hole forming problem of the complex auxiliary truss inclined rod upper-layer and lower-layer bolt connecting portion is solved; and effective and accurate connection of the auxiliary truss inclined rods and accurate connection of transverse gradient and longitudinal ports of an upper-layer bridge deck structure are guaranteed.
本发明公开了一种双层钢结构桥梁副桁试拼方法，属于钢结构桥梁领域，其技术方案要点是，包括如下步骤：S1、搭设胎架；S2、主桁片拼装，依次拼装上弦杆、下弦杆、腹杆，直至本轮次主桁片杆件全部拼装完成；S3、上弦边纵梁、副桁斜杆拼装，依次拼装上弦边纵梁、副桁斜杆，直至本轮次所有节段拼装完成；S4、孔群配钻，利用副桁斜杆孔群配钻上弦边纵梁孔群，利用标准拼接板配钻上弦边主纵梁上加劲板孔群、连接板孔群均采用先孔法在试拼前完成钻孔。采用该种双层钢结构桥梁副桁试拼方法，解决了复杂的副桁斜杆上、下层螺栓连接部位的制孔问题；保证了副桁斜杆有效、准确地连接，以及上层桥面结构横向坡度、纵向端口精确连接。
