一种预制预应力混凝土梁与钢混组合梁拼接桥及施工方法
一种预制预应力混凝土梁与钢混组合梁拼接桥及施工方法，拼接桥由预制混凝土箱梁/T梁与钢箱梁/工字钢截面钢混组合梁直接连接构成。施工方法为：在施工场地附近预制场内制作预制混凝土箱梁/T梁；在工厂制作钢箱梁/工字钢截面钢混组合梁；预先张拉预应力钢筋，将预制混凝土箱梁/T梁与钢箱梁/工字钢截面钢混组合梁对接，使高强螺栓插入螺栓孔并利用螺母固定；预应力钢筋穿过预应力钢筋孔并利用锚具固定；在钢混组合梁的端部钢板与锚固钢板之间利用后浇混凝土封装；对于采用精轧螺栓的形式，两梁对接时精轧螺栓会穿入螺栓穿装孔内，利用螺母固定并由混凝土封装；对于采用预应力锚索的形式，两梁对接后，将预应力锚索穿入后两端固定并由混凝土...

The invention discloses a prefabricated prestressed concrete beam and steel-concrete composite beam spliced bridge and a construction method. The spliced bridge is formed by directly connecting a prefabricated concrete box beam/T beam and a steel box beam/I-shaped steel section steel-concrete composite beam. The construction method comprises: manufacturing the precast concrete box girder/T girderin a precast yard near a construction site; manufacturing a steel box girder/I-shaped steel section reinforced concrete composite girder in a factory; pre-tensioning the prestressed reinforcements, butting the prefabricated concrete box girder/T-shaped girder with the steel box girder/I-shaped steel section reinforced c |
