[0002] In building engineering structures, the connection method between prefabricated steel beams and floor slabs is crucial and directly related to space utilization, construction progress and project cost. Most prefabricated beam-slab connection methods are to place the slabs on top of the beams in different ways to complete the construction of the floor system, but this reduces the space utilization rate to a certain extent. Making the floor slab flush with the upper surface of the steel beam can improve the space utilization rate, but it requires on-site formwork and concrete pouring during construction, which slows down the construction progress.
