Technical Field

[0001] The utility model relates to the technical field of truss floor decking plates, in particular to a truss floor decking plate which is easy to disassemble and assemble. Background Art

[0002] The production process of truss floor decking is much more optimized than that of traditional floor decking, eliminating a large number of high-altitude operations, saving labor costs and time costs, greatly improving work efficiency in the same period of time, and modern machinery and equipment also ensure product quality and reduce the probability of rework and inferior quality. Therefore, floor decking manufacturers have increased their investment in steel truss floor decking in recent years, and strictly control the details in every link of production, processing, installation and construction;

[0003] The utility model patent with the announcement number CN215594548U discloses a steel truss floor deck that is easy to disassemble and assemble. By setting the plug block in the slide groove and the slot on the installation block to be plugged in, the bottom plate and the steel truss can be conveniently installed and fixed, and no other connecting parts are required for connection, which effectively avoids the deformation of other connecting parts under stress during construction, resulting in reduced efficiency of bottom plate disassembly, improves the disassembly efficiency of the bottom plate, and avoids damage to the bottom plate and poured concrete during the separation process, which affects subsequent use, and extends the service life of the bottom plate;
