Method for installing anchor pullingplate on steel box girder
The invention discloses a method for installing an anchor pulling plate on a steel box girder, belongs to the field of cable-stayed bridge construction, and is characterized by comprising the following steps of: S1, making an auxiliary line and an anchor pulling plate system line which are parallel to the longitudinal axis of an anchor pipe on a web plate of the anchor pulling plate; S2, making asteel box girder system line matched with the anchor pulling plate on the steel box girder; S3, aligning the anchor pulling plate system line with the steel box girder system line, and positioning a longitudinal angle [alpha] by utilizing the auxiliary line; S4, positioning a transverse angle [delta]; and S5, rigidly fixing inclined struts, so that the anchor pulling plate is kept in a positioningstate, and meanwhile, welding and fixing the bottom plate of the anchor pulling plate to the top surface of the steel box girder. By the adoption of the installation method of the anchor pulling plate on the steel box girder, the anchor pulling plate and the steel box girder are manufactured in a split mode, transportation of the anchor pulling plate and the steel box girder can be facilitated, and over-height and over-limit transportation of a girder section is avoided; and after the steel box girder is installed, the anchor pulling plate is measured, positioned and installed on site, and the positioning precision of the anchor pulling plate can be ensured.
本发明公开了一种钢箱梁上的锚拉板安装方法，属于斜拉桥施工领域，其技术方案要点是，包括如下步骤：S1、在锚拉板腹板上作出平行于锚管纵向轴线的辅助线、锚拉板系统线；S2、在钢箱梁上作出与锚拉板匹配的钢箱梁系统线；S3、将锚拉板系统线与钢箱梁系统线对齐，并利用辅助线定位纵向角度α；S4、定位横向角度δ；S5、斜撑刚性固定，使得锚拉板保持定位状态，同时将锚拉板的底板与钢箱梁顶面焊接固定。采用该种钢箱梁上的锚拉板安装方法，将锚拉板与钢箱梁分体制作，能够便于锚拉板与钢箱梁的运输，避免了梁段运输超高、超限；在钢箱梁安装完成后，现场进行锚拉板测量定位及安装，可以确保锚拉板的定位精度。
