In addition, the strengthening structure can improve the stability of the connection between the two sets of bottom plates.

[0014] 2. When the truss floor deck is in use, first, align the mounting threaded hole on the bottom wall of the mounting block with the mounting threaded hole on the top of the first base plate, then, sleeve the mounting gasket on the side wall of the mounting bolt, and then rotate the mounting bolt to insert it into the inside of the mounting threaded hole, then, the mounting block can be fixedly installed on the top of the first base plate, so that the main assembly can be installed and fixed on the top of the first base plate, and then, the plug-in plate and the plug-in slot are plugged and fixed, and multiple groups of clamping blocks are clamped and fixed with multiple groups of clamping slots, so that the first base plate and the second base plate can be preliminarily connected, and then, after the threaded holes on the side walls of the two groups of fastening side plates are closely aligned, the fastening bolts are inserted into the inside of the fastening side plates through the fastening threaded holes, and then the nuts and one end of the fastening bolts are assembled and fixed, so that the stability of the connection between the two groups of base plates can be improved, and then the assembly and installation of the two groups of base plates can be completed;

[0015] 3. Furthermore, a steel structure truss floor deck structure body can be formed by the first base plate, the mounting block, the mounting frame and the corrugated steel bars. Furthermore, by providing multiple groups of corrugated steel bars, cracking of concrete after pouring can be avoided. At the same time, by the mutual snap-fitting between the snap-fitting blocks, the snap-fitting holes, the plug-in plates and the plug-in slots, the connection gap between the two groups of base plates can be reduced, thereby effectively avoiding the falling of cement.
