[0025] The utility model provides a technical solution: comprising a composite beam assembly 1, wherein a prefabricated plate assembly 2 is arranged at the top of the composite beam assembly 1, wherein the composite beam assembly 1 comprises a bottom plate 101, wherein a plurality of webs 102 are fixedly installed on the top surface of the bottom plate 101 from the front end to the rear end in sequence, wherein a plurality of mitered sockets 103 are opened on the top surfaces of the plurality of webs 102 in sequence from one side to the other side, wherein two vertical baffles 104 are fixedly installed on both sides of the top surfaces of the plurality of webs 102, wherein a group of L-shaped embedded baffles 106 are fixedly installed on the front side of the web 102 at the front end and the back side of the web 102 at the rear end, wherein a limit plate 107 is slidably inserted in each group of L-shaped embedded baffles 106;

[0026] The prefabricated panel assembly 2 includes a prefabricated panel body 201 , and a plurality of miter plug-ins 202 are fixedly installed on the bottom surface of the prefabricated panel body 201 from one side to the other side in sequence. The plurality of miter plug-ins 202 correspond to a plurality of miter sockets 103 one by one, and the miter plug-ins 202 are movably plugged into the miter sockets 103 .
