Middle plate filling core shear-resistant reinforcing device for existing hollow plate girder bridge and construction method of middle plate filling core shear-resistant reinforcing device
The invention relates to an existing hollow plate girder bridge middle plate filling core shear-resistant reinforcing device and a construction method, and is characterized in that the device comprises a notch which is chiseled in the top of a bridge hollow plate and is communicated with a cavity of the bridge hollow plate, and a plurality of shear inclined ribs are arranged in the notch in the transverse width direction of the notch at intervals; the shear inclined ribs are bound together with a steel bar frame exposed out of the bridge hollow slab through digging, the two longitudinal ends of the notch are fixedly provided with blocking plates to block a cavity of the bridge hollow slab, and concrete is poured into a cavity formed by the two blocking plates and the notch. The shear capacity of the existing hollow slab girder bridge can be conveniently and effectively improved, meanwhile, the stress form of an original bridge is not changed as much as possible, and the bearing capacity of the existing hollow slab girder bridge is enhanced.
本发明涉及一种既有空心板梁桥中板填芯抗剪加固装置及施工方法，其特征在于：包括凿设于桥梁空心板顶部且与其空腔相通的槽口，所述槽口内沿其横向宽度方向间隔设置有若干受剪斜筋，该受剪斜筋均与桥梁空心板内经开凿露出的钢筋框架绑扎在一起，所述槽口纵向两端均固设有堵板以封堵桥梁空心板空腔，并于两堵板与槽口组成的腔室内浇筑有混凝土，该装置结构简单，能够便捷有效地提高既有空心板梁桥的抗剪能力，同时尽可能不改变原桥的受力形式，增强既有空心板桥梁的承载能力。
