Hollow slab girder bridge capable of preventing support from disengaging and construction method of hollow slab girder bridge
The invention discloses a hollow slab girder bridge capable of preventing supports from disengaging and a construction method of the hollow slab girder bridge. The two ends of all prefabricated hollow slabs of the same span are supported and connected to two prefabricated cover beams correspondingly, and each prefabricated cover beam is supported on two bridge piers through two supports correspondingly; embedded grouting sleeves are distributed at the two ends of the bottom face of the prefabricated hollow slab, hollow slab embedded hinge joint steel bars are distributed along the line of the side face where the hinge joint is located, and grouting holes and grout outlet holes used for grouting are distributed in the side faces near the embedded grouting sleeves. Bent cap pre-embedded hinge joint steel bars are distributed at the hinge joint position of the top face of the prefabricated bent cap, and pre-embedded sleeve steel bars are correspondingly distributed at the position of the pre-embedded grouting sleeve. The bottom faces of the prefabricated hollow slabs are supported on the top face of the prefabricated cover beam, the pre-embedded grouting sleeves are inserted into the corresponding pre-embedded sleeve steel bars and filled with grouting materials, the hollow slab pre-embedded hinge joint steel bars of the adjacent prefabricated hollow slabs are connected in hinge joints, and the hinge joints are filled with post-poured concrete. According to the invention, the support is prevented from disengaging, and the transverse overall rigidity and the shear bearing capacity of the hinge joint are improved.
本发明公开了一种防支座脱空的空心板梁桥及其施工方法，同跨所有的预制空心板在两端分别支撑连接在两片预制盖梁上，单片预制盖梁通过两个支座分别支撑在两个桥墩上；预制空心板的底面两端分布有预埋灌浆套筒、铰缝所在侧面沿线分布有空心板预埋铰缝钢筋、预埋灌浆套筒附近侧面分布有用于灌浆的压浆孔和出浆孔；预制盖梁顶面的铰缝位置分布有盖梁预埋铰缝钢筋、预埋灌浆套筒位置对应分布有预埋套筒钢筋；预制空心板底面支撑在预制盖梁顶面上，预埋灌浆套筒插放在对应预埋套筒钢筋上并通过灌浆料填充，相邻预制空心板的空心板预埋铰缝钢筋在铰缝内相互连接，铰缝通过后浇混凝土填充。本发明避免了支座脱空，提高了横向整体刚度和铰缝抗剪承载力。
