Manufacturing method of box-type bridge chord member
The invention discloses a manufacturing method of a box-type bridge chord member. The manufacturing method comprises the following steps: splicing and butting thick and thin plates of a box girder wall plate on a horizontal jig frame, marking and positioning the central lines of a node plate and a butting plate and the central line of a node of a connecting web member in advance, and assembling and welding a stiffener, a stiffening plate and the box girder wall plate; the transverse stiffening partition plates are mounted in the box body; the other box girder wall plate is installed; the top plate is hoisted, the top plate and the stiffening ribs are assembled and welded in advance, and penetration welds are formed between the stiffening ribs and the top plate; the transverse partition plates on the outer side of the box girder wall plate and the outer side of the box body are sequentially hung on the jig frame; the bottom plate unit is hung on a jig frame to be assembled and positioned; by means of the reasonable construction method, different welding modes are adopted for assembling and welding according to different installation positions of different components, the manufacturing quality of the whole box-type bridge chord member can be effectively improved, the stability of connection between the box-type bridge chord member and a bridge floor and between the box-type bridge chord member and a box-type end beam is guaranteed, and the construction efficiency is improved. And the supporting performance, the bearing performance and the later use safety are ensured.
本发明公开了一种箱型桥弦杆的制作方法包括箱梁壁板先在水平胎架上进行厚薄板的拼板对接，节点板、对接板中心线及连接腹杆节点中心线预先划线定位，并将加劲助和加劲板与箱梁壁板间进行组装焊接；安装箱体内部的横向加劲隔板；安装另一块箱梁壁板；吊装顶板，顶板预先与加劲肋进行组装焊接，加劲肋与顶板间为熔深焊缝；将箱梁壁板外侧箱体外侧横隔板依次吊上胎架；将底板单元吊上胎架进行组装定位；然后装焊第一支座和一组第二支座，本发明通过合理的施工方法，根据不同部件安装位置的不同采用不同的焊接方式进行装焊，能够有效的提高整个箱型桥弦杆的制作质量，保证其与桥面和箱型端梁连接的稳定性，保证其支撑性、承载性和后期使用的安全性。
