[0002] Fabricated building is the building which is made of building components and accessories (such as floor, wallboard, stairs, balcony, etc.) processed in the factory, transported to the construction site, and assembled and installed on site by reliable connection. In order to reduce the structure weight and save steel, a large number of new lightweight prefabricated building wallboards and prefabricated floors appear on the market, which puts forward new problems for the reliability of wallboard installation and the integrity of floor installation. In terms of ensuring the integrity of prefabricated floor installation, the conventional method is to set a concrete cast-in-place strip between the prefabricated floor panels, set a tie steel along the joint, set a reinforced concrete cast-in-place layer on the panel surface, and set a shear connector on the panel side. These structural measures have problems such as more wet work on site, large amount of steel binding or inconvenient installation, which affects the construction period and is not conducive to cost reduction and efficiency improvement.
