Composite heat-insulating superimposed sheet

The invention belongs to the technical field of constructional engineering and discloses a composite heat-insulating superimposed sheet integrated with a concrete body structure. The sheet is characterized in that interface agent protective layers are arranged on both sides of a polystyrene board, bidirectional high-strength steel wires which are inserted obliquely are distributed inside the polystyrene board, and a single side of the polystyrene board is covered by and welded with a steel wire mesh, accordingly, a heat-insulating plate with the whole welding steel wire frame is formed, wherein obliquely-inserted steel wires penetrate through the polystyrene board. The steel wire mesh is wrapped in a light composite concrete layer, the light composite concrete layer is combined with an extruded sheet through an interface agent to form the heat-insulating plate, an anchor bolt hole is arranged on the heat-insulating plate, a counter bored hole is arranged on the light composite concrete layer corresponding to
