Beam-to-beam top static load test method for prefabricated large-span composite beam

The invention relates to an inter-beam butting static load test method for a prefabricated large-span composite beam, which comprises the following steps of: stacking two prefabricated composite beams up and down at an interval, then connecting the two ends of the two composite beams up and down, and arranging a jacking mechanism between the two composite beams to jack the upper-layer composite beam so as to load concentrated force on the lower-layer beam to carry out a static load test. According to the invention, the two beams are stacked by using the existing prefabricated composite beams and hoisting equipment in a beam factory, concentrated force is loaded on the lower-layer beam for experiment through the opposite jacking effect of the jacking mechanism and the constraint effect of the beam end connecting structure, the experiment method is simple and reliable, and the experiment cost is low. 本发明涉及一种用于预制大跨度组合梁的梁间对顶静载试验方法，是将预制好的两片组合梁上下间隔叠放后将两片组合梁的两端上下连接，两片组合梁之间设置顶升机构将上层组合梁顶升实现将集中力加载于下层梁上进行静载试验。本发明利用梁厂内已有
