System and method for improving overall rigidity of hollow slab girder bridge
The invention discloses a system and method for improving the overall rigidity of a hollow slab girder bridge, the hollow slab girder bridge comprises a plurality of hollow slab girders arranged side by side and a bridge deck pavement arranged on the surfaces of the hollow slab girders, hinge joints are arranged among the hollow slab girders, and the system comprises a profile steel grid, a plurality of anchoring blocks and a plurality of prestress connectors; the profile steel grid comprises cross beams and longitudinal beams which are fixedly connected transversely and longitudinally, and the profile steel grid is fixed on the lower surface of the hollow slab beam; the anchoring blocks are fixed between the hollow slab beams and located on the upper portions of the hinge joints. The prestress connector is arranged between the profile steel grid and the anchoring block, and the two ends of the prestress connector are fixedly connected with the profile steel grid and the anchoring block respectively. The transverse and longitudinal overall rigidity of the hollow slab girder bridge can be improved, the reinforcing effect is good, durability is high, the construction technology is simple, maintenance is easy, and cost is low.
本发明公开了一种空心板梁桥整体刚度提升系统及方法，所述空心板梁桥包括多根并排设置的空心板梁以及设于空心板梁表面的桥面铺装，所述空心板梁间设有铰缝，所述系统包括型钢网格、多个锚固块和多个预应力连接器；所述型钢网格包括横纵向固定连接的横梁和纵梁，所述型钢网格固定于空心板梁的下表面；所述锚固块固定于各空心板梁之间且位于铰缝上部；所述预应力连接器设于型钢网格和锚固块间，且两端分别与型钢网格和锚固块固定连接。本发明能够对空心板梁桥的横纵向进行整体刚度的提升，加固效果好，耐久性强，施工工艺简单，易于维护且成本低。
