Continuous beam side pier beam section bracket balance cast-in-place construction method
The invention provides a continuous beam side pier beam section bracket balanced cast-in-place construction method. The continuous beam side pier beam section bracket balanced cast-in-place construction method comprises the following steps: (1) symmetrically installing side pier brackets, wherein the bracket longitudinal beams are I-shaped steel, three trusses of bracket longitudinal beams are arranged in the transverse direction of the bridge, a transverse connecting line is arranged between the horizontal longitudinal beams and the inclined struts, and the bracket longitudinal beam embeddedparts are provided with opposite-pull prestressed tendons; (2) completing bracket pre-pressing by a down-drawing method; (3) pulling down to finish first-stage bending moment balance weight; (4) completing beam section steel bar binding construction, completing bottom plate concrete pouring, completing second-stage bending moment balance weight, completing web concrete pouring, completing the third time of torque conversion counterweight, and completing roof concrete pouring. The construction method is safe and reliable in technology and simple and convenient in construction process, solves the problem that the construction of the side-pier side-span cast-in-place beam section is difficult to hoist due to site limitation under complex terrain construction conditions, reduces the construction cost of the high-pier side-span cast-in-place beam section, avoids erection of a large number of brackets, shortens the construction period and improves the work efficiency.
本发明提供一种连续梁边墩梁段托架平衡现浇施工方法，包括以下步骤：步骤(1).对称安装边墩托架；托架纵梁为工字钢，托架横桥向布置3榀，水平纵向和斜撑之间设置横向连接系，托架纵梁预埋件设置对拉预应力筋；步骤(2).下拉法完成托架预压；步骤(3).下拉完成第一级弯矩配重；步骤(4).完成梁段钢筋绑扎施工；完成底板混凝土浇筑；完成第二级弯矩配重；完成腹板混凝土浇筑；完成第三次变矩配重；完成顶板混凝土浇筑。本发明技术安全、可靠，施工流程简便，解决了边墩边跨现浇梁段施工在复杂地形施工条件下受场地限制吊装作业困难问题，降低了高墩边跨现浇梁段的施工成本，避免了大量的支架搭设，缩短了施工工期，提高了工效。
