[0002] In general lattice column support systems, in order to ensure the slenderness ratio of the lattice columns, the concrete floor slab is generally cast together with the structural columns. In the later stage, when the lattice columns are breaking the upper layer of supporting concrete nodes and the trestle concrete nodes, large vibrations will occur, which can easily cause the floor slab to crack. Each time they are broken, the nodes need to be broken and re-cast or the nodes here need to be strengthened. The breaking and re-casting process is relatively complicated, so a prefabricated concrete slab is required to achieve rigid splitting of the two and realize rapid disassembly and assembly.

[0003] When the existing quick-release column-plate connection structure is used, the steel bar needs to be pulled out by rotating the steel bar with a wrench. The operation of removing the steel bar is too troublesome and takes too much time, which is not conducive to the use of the device. Utility Model Content
