Bridge prestress construction device
The invention relates to the technical field of bridge construction, in particular to a bridge prestress construction device which comprises a suspension grouting support, a prestress tensioning device and an adjusting device. The suspension irrigation support comprises an upper pedestal and a lower pedestal, and the prestress tensioning device is connected with the upper pedestal and the lower pedestal. The adjusting device is arranged on one side of the suspension irrigation support, connected with the upper pedestal and the lower pedestal and used for adjusting the distance between the upper pedestal and the lower pedestal. A suspension grouting support and a prestress tensioning device are arranged, pre-tensioning method construction is adopted for vertical prestress, the problem caused by non-compact prestress mud jacking in a post-tensioning method is solved, and the construction technology is simpler compared with the post-tensioning method; and by arranging the adjusting device, the device can adapt to different construction section heights and is convenient to disassemble and assemble.
本公开涉及桥梁施工技术领域，尤其涉及一种桥梁预应力施工装置，包括悬灌支架、预应力张拉装置、调节装置；悬灌支架包括上台座和下台座，预应力张拉装置连接上台座和下台座；调节装置设置在悬灌支架的一侧，调节装置连接上台座和下台座，调节装置用于调节上台座与下台座的间距。通过设置悬灌支架、预应力张拉装置，竖向预应力采用先张法施工，解决了后张法预应力压浆不实带来的问题，施工工艺与后张法相比较也比较简单；而且通过设置调节装置，可以适应不同施工截面高度，拆装便捷。
