Construction method for transversely moving and erecting steel plate composite beam
The invention discloses a construction method for transversely moving and erecting a steel plate composite beam. The method comprises the following steps of: firstly, erecting a temporary bracket forerecting a beam body, installing a slideway beam on a bracket cross beam, and installing a sliding groove in the slideway beam; arranging a sliding block in the sliding groove, fixing an adjustable screw rod to the sliding block through a steel pin, enabling the top of the adjustable screw rod to abut against the steel plate composite beam, and using a continuous jack fixed to the slideway beam topull a steel strand connected with the sliding block to achieve transverse movement of the composite beam; and after the transverse movement in place, finely adjusting the beam section through a three-way jack arranged on the bracket cross beam until the precision requirement is met, and continuously finishing the subsequent connection and installation of the steel plate composite beam. The construction method is safe, reliable and easy to install. The difficulties that in urban bridge construction, normal hoisting cannot be achieved due to the influence of high-voltage lines and the clearance influence of an existing viaduct are fully considered, and the construction method using the continuous jack and the steel strand to pull the sliding block to transversely move the composite beam isused to solve the problem that the clearance of hoisting operation is not enough.
本发明公开了一种钢板组合梁横移架设的施工方法，该方法包括以下步骤：首先搭设梁体架设的临时支架，在支架横梁上安装滑道梁，在滑道梁上安装滑槽；滑块置于滑槽内，滑块上用钢销固定可调节螺旋杆，可调节螺旋杆顶部与钢板组合梁顶紧，通过固定在滑道梁上的连续千斤顶拉动连接滑块的钢绞线实现组合梁横移；横移到位，通过安装在支架横梁上的三向千斤顶微调梁段直至满足精度要求，继续完成后续钢板组合梁连接安装。本施工方法安全可靠，安装简单。充分考虑到了城市桥梁建设中，受到高压线影响、既有高架桥的净空影响而无法正常吊装等困难，利用连续千斤顶和钢绞线牵引滑块进行组合梁横移的施工方法，解决受吊装作业净空不够的问题。
