Anti-seismic floor connecting assembly for modular building Technical Field This document relates to an earthquake-resistant floor connection assembly for a modular building. Background In the development process of the building industry, the traditional pouring type building has obvious defects. The construction process depends on a large amount of site construction, so that the construction period is long, and the time from the foundation construction to the completion of the main structure often needs months or even longer, so that the time cost is increased, the construction process is greatly influenced by natural factors such as weather and the like, and the condition of delay of construction period is easy to occur. Meanwhile, the structural strength of the traditional pouring type building depends on quality control of site construction to a great extent, such as proportioning of concrete, pouring process, maintenance conditions and the like, and once a certain link is in a problem, the structural strength possibly cannot reach the standard, and potential safety hazards exist. Along with the continuous promotion of building industrialization and green environmental protection concepts, prefabricated assembled buildings gradually become the development trend of the building industry. The prefabricated building is prefabricated in a factory, and then transported to the site for installation, so that the site construction time is greatly shortened, the construction efficiency is improved, and the quality of the building is better controlled. However, the design of the connections between prefabricated components is one of the key problems faced by prefabricated building. In engineering applications, it is often difficult and heavy to use conventional pre-embedding means for the connection of prefabricated panels, in particular lightweight panels such as aerated concrete panels, to other prefabricated panels or to body structures and peripheral components. The traditional pre-buried mode needs to accurately set the embedded part when the component is prefabricated, so that the requirement on the prefabrication process is extremely high, once deviation occurs, the embedded part is difficult to adjust during field installation, connection is unstable easily, and the structural stability and safety of the whole building are affected. Therefore, there is an urgent need for a simple, flexible, safe and reliable connection method to solve this problem.
