Bridge deck slab pre-tightening system and bridge deck slab pre-tightening construction method
The invention provides a bridge deck slab pre-tightening system and a bridge deck slab pre-tightening construction method.The bridge deck slab pre-tightening system comprises a steel cross beam, a bridge deck slab pre-tightening device and a bridge deck slab pre-tightening device, the outer sides of the bridge deck slabs located at the two ends of the steel cross beam abut against the check blocks located at the two ends of the steel cross beam, and the length direction of the bridge deck slabs is the same as the length direction of the steel cross beam; the pre-tightening jacks are arranged between the adjacent bridge deck slabs and used for applying pre-tightening force to the bridge deck slabs in the length direction of the bridge deck slabs so as to enable the bridge deck slabs to be compressed in the length direction, and when the pre-tightening force applied to the bridge deck slabs by the pre-tightening jacks reaches a target value, the pre-tightening jacks are used for pre-tightening the bridge deck slabs in the length direction of the bridge deck slabs. The jacking force is continuously kept so that the bridge deck slab can be kept in a pre-tightening state; and the two isolation templates are arranged on the two sides of the pre-tightening jack, so that an isolation space is formed, and the pre-tightening jack is isolated from the outside. The bridge deck slab pre-tightening system has good economical efficiency and safety.
本发明提供一种桥面板预紧系统及桥面板预紧施工方法，其中桥面板预紧系统，包括：钢横梁，两端设置有挡块；桥面板，位于所述钢横梁两端的桥面板的外侧均与位于所述钢横梁两端的所述挡块抵触，所述桥面板的长度方向与所述钢横梁的长度方向相同；预紧千斤顶，所述预紧千斤顶设置于相邻的所述桥面板之间，用于对桥面板施加沿其长度方向上的预紧力，以使得桥面板在长度方向上被压缩，当所述预紧千斤顶对所述桥面板施加的预紧力达到目标值时，持续保持顶力以使得所述桥面板保持预紧状态；隔离模板，两个所述隔离模板设置在所述预紧千斤顶的两侧，以形成一个隔离空间而将所述预紧千斤顶与外界隔离。上述桥面板预紧系统具有较好的经济性和安全性。
