Steel truss girder end connecting process
The invention discloses a steel truss girder end connection process, which belongs to the technical field of steel bridge connection processes, and comprises the following steps that a male joint of a to-be-spliced beam section port is jacked and inserted into a female joint of a spliced beam section port, the female joint of the spliced beam section port is provided with a jacking counter-force plate, the jacking counter-force plate is connected with a tensioning jacking device, and the tensioning jacking device is connected with a tensioning device; the to-be-spliced beam section port male joint is jacked towards the spliced beam section port female joint through a tensioning jacking device; after the to-be-spliced beam section port male joint is initially jacked in, a plurality of locking base plates are filled between the to-be-spliced beam section port male joint and the to-be-spliced beam section port male joint; and the stiffening rib plate of the male connector of the port of the to-be-spliced beam section is welded with the jacking counter-force plate, the top and bottom webs of the male connector of the port of the to-be-spliced beam section are welded with the jacking counter-force plate, and the welt position of the locking base plate is welded. The durability and safety of the steel truss girder connecting interface can be improved, and the construction control precision of the main truss line shape is further improved.
本发明公开了一种钢桁梁端头连接工艺，钢桥连接工艺技术领域，包括以下步骤：将待拼梁段端口公接头顶进插入到已拼梁段端口母接头中，已拼梁段端口母接头设置有顶进反力板，顶进反力板连接有张拉顶进装置，待拼梁段端口公接头通过张拉顶进装置向已拼梁段端口母接头方向顶进；待拼梁段端口公接头初步顶入后，在待拼梁段端口公接头和待拼梁段端口公接头之间填入若干个锁定垫板；将待拼梁段端口公接头的加劲肋板与顶进反力板进行施焊，将待拼梁段端口公接头的顶底腹板与顶进反力板进行施焊，将锁定垫板的贴边位置进行施焊。本发明能提高钢桁梁连接接口的耐久性和安全性，进一步提升主桁线形的施工控制精度。
