Beam bridge composite structure of inverted-groove-shaped steel-concrete bridge deck slab and construction method thereof
The invention discloses a beam bridge composite structure of an inverted-groove-shaped steel-concrete bridge deck slab and a construction method thereof. The inverted-groove-shaped steel-concrete bridge deck slab beam bridge composite structure comprises two supporting structures, a hot-rolled H-shaped steel beam set, a plurality of bridge deck slabs and finish-rolled deformed steel bars, whereinthe hot-rolled H-shaped steel beam set is provided with a plurality of hot-rolled H-shaped steel beams, the hot-rolled H-shaped steel beams are transversely erected between the two supporting structures, and support seats are arranged between the hot-rolled H-shaped steel beams and the supporting structures; the bridge deck slabs are sequentially and flatly laid on the two adjacent hot-rolled H-shaped steel beams in the vertical direction of a connecting line of the two supporting structures to form a bridge deck; and the finish-rolled deformed steel bars penetrate through the preformed holesof the bridge deck in the vertical direction of the connecting line of the two supporting structures, and then the multiple bridge deck slabs are spliced. A common steel plate beam is replaced with the hot-rolled H-shaped steel beams, the hot-rolled H-shaped steel beams are wide in flange plate width, large in lateral rigidity, high in bending resistance, good in local stability, high in quality guarantee level and so on, and under the condition that the same bearing capacity is achieved, steel is saved by about 5%-10% compared with welded ''I''-shaped steel.
本发明公开了倒槽形的钢‑混凝土桥面板的梁桥组合结构及其施工方法，其中，倒槽形的钢‑混凝土桥面板的梁桥组合结构包括：两个支撑结构；热轧H型钢梁组，具有多根热轧H型钢梁，热轧H型钢横架在两个支撑结构之间，热轧H型钢和支撑结构之间设有支座；多块桥面板，桥面板依次沿两个支撑结构连线的垂直方向平铺在相邻两根热轧H型钢梁后形成桥面；以及精轧螺纹钢钢筋，沿两个支撑结构连线的垂直方向穿过桥面板的预留孔后，将多个桥面板拼接。采用热轧H型钢梁代替常用钢板梁，热轧H型钢梁具有翼缘板宽、侧向刚度大、抗弯能力强、局部稳定性好、质量保证水准高等优势，在具有相同承载能力的情况下，比焊接“工”字钢节省钢材大约5‑10％。
