Shear-resistant reinforcing device for hinge joint steel plate of middle plate of existing hollow plate girder bridge and construction method
The invention relates to an existing hollow plate girder bridge middle plate hinge joint steel plate shear-resistant reinforcing device and a construction method, the existing hollow plate girder bridge middle plate hinge joint steel plate shear-resistant reinforcing device comprises a girder bridge composed of a plurality of hollow plates, hinge joints are formed between the adjacent hollow plates, reinforcing steel plates are embedded in the hinge joints, and the reinforcing steel plates are composed of channel steel and steel plates; the channel steel longitudinally and horizontally extends, the steel plate is vertically and fixedly connected to the lower end of the channel steel so as to be inserted and embedded into the hinge joint, the transversely adjacent hollow plates are fixedly connected with the reinforcing steel plate by filling a joint pouring material, and the longitudinally adjacent hollow steel plates are fixedly connected with the reinforcing steel plate through a continuous cast-in-place section; the hollow slab bridge structure is reasonable in structure and good in mechanical property, the steel plates and the channel steel are additionally arranged by fully utilizing the hinge joints between the hollow slabs and the space of the pavement layer, and therefore the shear resistance and bending resistance bearing capacity of the hollow slab bridge structure can be improved, and the transverse connecting capacity between the hollow slabs can be improved; in the old bridge reinforcing process, the modification cost is low, and the construction method is simple, convenient and practical.
本发明涉及既有空心板梁桥中板铰缝钢板抗剪加固装置及施工方法，包括由若干空心板组成的梁桥，相邻的空心板间均开设铰缝并于铰缝内插嵌有加固钢板，所述加固钢板均由槽钢与钢板组成，所述槽钢纵向水平延伸且钢板竖向固连在槽钢下端以插嵌入铰缝，横向相邻的空心板间经填充灌缝材料与加固钢板固连，纵向相邻的空心钢板间经连续现浇段与加固钢板固连；本发明结构合理、力学性能良好，充分利用空心板间铰缝及铺装层的空间增设钢板及槽钢，从而可以提高空心板桥梁结构的抗剪及抗弯承载能力，并能提高空心板间的横向连接能力，且本发明在旧桥的加固过程中改造成本低、施工方法简便实用。
